ARTICLE 4. EXAMINATION OF DOCUMENTS AND SITE The CONTRACTOR confirms that it has carefully examined the Site, as well as its surrounding territory. As a result, the CONTRACTOR acknowledges that it is fully informed regarding all existing conditions, both natural and manmade, as well as all such above grade, at grade and subsurface conditions that may in any way affect the Work to be done and labor and materials to be furnished for the proper completion of the Project, including, by way of example, the existence of poles, wires, pipes, ducts, conduits and other facilities and

The CONTRACTOR shall contribute to and cooperate with the development of the Project schedules and other efforts to achieve timely completion of the Work. The CONTRACTOR shall be required to provide information for the scheduling of the times and sequence of operations required in order for its Work to meet the CITY's overall schedule requirements and it shall continuously monitor the Project schedule so as to be fully familiar with the timing, phasing and sequence of operations of the Work and of any other work performed by others on the Project. The CONTRACTOR shall diligently execute the Work in accordance with the requirements of the Project schedule including any revisions thereto.

Notwithstanding the foregoing, if any of the Contract Documents are at variance with granting such time extension, then the provisions of such documents shall control.

In addition, the CONTRACTOR shall not only fulfill all of its obligations imposed by this Contract at its own cost and expense, but also work such overtime as may be necessary to make up for all time lost in the performance of the Work


and of the Project.

The cost and expense of such overtime and/or such other action, including all other consequential damages and expenses, shall be borne by the CONTRACTOR hereunder. ARTICLE 6. CONTINGENCIES, EXTRA WORK, AND CHANGES Whenever the CITY determines that, for any reason deemed to be in the best interests of the Project, the scope of Work or plans for the Project should be revised to provide for changes, deletions, contingencies, additional or extra work, it may issue a Change Order to the CONTRACTOR. Once the CITY has issued and signed a written Change Order in its standard form, the CONTRACTOR shall forthwith comply with the specifications of such Change Order. In such event, allowances for additions and/or deductions to the prices listed in the bid documents will be made commensurate with such changes in the scope or extent of the Work. Any such action by the CITY shall not constitute grounds for a claim by the CONTRACTOR for damages, loss of anticipated profits, or for costs resulting from any variations between the approximate quantities and quality of Work contemplated in the bid documents and as built. All changes, additions or omissions in the Work ordered in writing by the CITY shall be deemed to be a part of the Work hereunder and shall be performed and furnished in strict accordance with all of the terms and provisions of the Contract Documents based on a negotiated cost for the Work and materials.

The obligations of CONTRACTOR's surety shall not be reduced, waived or adversely affected by the issuance of such Change Orders, additions or deductions and the CITY shall not be required to inform the surety of the same or to obtain the consent of the surety to such modifications. Payment for any unforeseen Work and/or changes shall be made as provided for in the Standard Specifications. ARTICLE 7.

procedures, in connection with the performance of the Work. CONTRACTOR further assumes responsibility for all actions and omissions of its agents, employees, subcontractors, suppliers and all of their respective agents, employees and any other person performing any part of the Work. ARTICLE 8. NO COLLUSION OR FRAUD The CONTRACTOR hereby agrees that all persons interested as principal or principals in the bid or proposal submitted by the CONTRACTOR for this Project are named therein; that this Contract has been secured without any connection with any person or persons other than those named; that this Contract was secured without collusion or fraud; and that neither any officer nor employee of the CITY, nor any member of the immediate family of any such person, has or will have a financial interest in the performance of this Contract, in the supplies, Work or business to which it relates, or in any portion of the profits thereof. ARTICLE 9. ESTIMATES AND PAYMENT As the Project progresses in accordance with the Contract and in a manner that is satisfactory to the CITY, the CITY hereby agrees to make payments to the CONTRACTOR, based upon the Contract Documents as follows: on or before the last day of each month the CONTRACTOR shall submit to the CITY, [in the form required by the CITY], a written Application For Payment showing the value of the Work installed to that date based on the quantity of work completed and the Contract unit prices, from which shall be deducted all previous payments and all charges for services, materials, equipment and other items chargeable to the CONTRACTOR. The balance of such Application must be approved by the CITY and should represent the value of Work done and material furnished in accordance with the terms and conditions of this Contract during the preceding month. The CONTRACTOR shall be paid ninety five (95%) percent of such amount. The five (5) percent retained shall be held by the CITY until final completion and acceptance of all Work covered by this Contract; compliance by the CONTRACTOR with all of its responsibilities hereunder including the provision of signed waivers of lien from CONTRACTOR, its subcontractors and suppliers; the posting of a twenty-five percent (25%) maintenance bond by the CONTRACTOR insuring the Project for a period of two (2) years from the date of final acceptance; and the making of all payments due all subcontractors and material suppliers in connection with the Project. Nothing herein shall modify or limit detailed payment provisions contained in the Contract Documents and approved by the Director. The CITY reserves the right to advance the date of any payment (including the final payment) under this Contract if, in its judgment, it becomes desirable to do so. The CONTRACTOR agrees that, if and when requested to do so by the


CITY, it shall furnish such information, evidence and substantiation as the CITY may require with respect to the nature and extent of all obligations incurred by the CONTRACTOR for or in connection with the Work, all payments made by the CONTRACTOR thereon, and the amounts remaining unpaid and the reasons therefor. The CONTRACTOR warrants that: (1) title to Work, materials and equipment covered by an Application for Payment will pass to the CITY either by incorporation in construction or upon receipt of any payment for the same by the CONTRACTOR, whichever occurs first; (2) Work, materials and equipment covered by Applications for Payment shall be free and clear of liens, claims, security interests or encumbrances; and (3) no Work, materials or equipment covered by an Application for Payment shall be acquired by the CONTRACTOR, or any other entity or person performing any Work at the Site or furnishing materials or equipment for the Project, subject to an agreement or arrangement under which any interest therein or an encumbrance thereon is retained by the seller of such or is otherwise imposed by the CONTRACTOR or such other entity or person. With each Application For Payment the CONTRACTOR shall certify to the CITY that the Work, for which payment is requested, has been fully completed in accordance with the Contract Documents; that all amounts owed to any subcontractor and subconsultant for Work or materials covered by all previous progress payments have been paid in full; and that the CONTRACTOR has no claim outstanding against the CITY related to this, or any previous progress payment, except any such claim as has been previously served by way of a detailed, verified statement upon the CITY prior to the filing of such Application For Payment. If requested to do so, the CONTRACTOR will file signed Waivers of Lien with each Application for Payment in a form satisfactory to the CITY. The CONTRACTOR's refusal to accept any payment as tendered shall constitute a waiver of any right to interest thereon. It is further agreed that so long as the CONTRACTOR fails to comply with any lawful or proper direction concerning the Work or material given by or on behalf of the Director, the CONTRACTOR shall not be entitled to have any estimate made for the purpose of payment. No such estimate shall be rendered until the CONTRACTOR fully and satisfactorily complies with all such directions. If any of the following occurs: (1) a claim or lien is made or filed with or against the CITY, the Project, or the Project funds by any person claiming that the CONTRACTOR or any subcontractor or other person under subcontract has failed to make payment for any labor, services, materials, equipment, taxes or other items or obligations furnished or incurred for or in connection with the Work; (2) there is evidence of such nonpayment or of any claim or lien for which, if established, the CITY might become liable and which is chargeable to the CONTRACTOR; (3) the CONTRACTOR or any subcontractor or other person under subcontract causes damage to the Work or to any other


work on the Project; (4) or if the CONTRACTOR fails to perform or is otherwise in default under any of the terms or provisions of this Contract, the CITY shall have the right to retain from any payment then due or thereafter to become due an amount which it deems sufficient to (i) satisfy, discharge and/or defend against any such claim or lien or any action which may be brought or judgment which may be recovered thereon, (ii) make good any such nonpayment, damage, failure or default, and (iii) compensate the CITY for and indemnify and hold it harmless against any and all actual or potential losses, liabilities, damages, costs and expenses, including legal fees and disbursements, which may be sustained or incurred in connection therewith. The CITY shall have the right to apply and charge against the CONTRACTOR so much of the amount retained as may be required for the foregoing purposes. If the amount is insufficient therefor, the CONTRACTOR shall be liable for the difference and promptly pay the same to the CITY. No person shall have any right or claim by reason of the CITY's failure or refusal to withhold monies. No interest shall be payable by the CITY on any amounts withheld under this provision. This provision is not intended to limit or in any way prejudice any other right of the CITY. No payment (final or otherwise) made under or in connection with this Contract shall be conclusive evidence of the proper performance of the Work or of this Contract, in whole or in part, and no such payment shall be construed to be an acceptance of defective, faulty or improper work or materials, nor shall it release the CONTRACTOR from any of its obligations under this Contract; nor shall entrance upon and use of the Site by the CITY constitute acceptance of the Work or any part thereof. ARTICLE 10. PAYMENT TO SUBCONTRACTORS AND SUPPLIERS The CONTRACTOR shall, within thirty (30) days after its receipt of payment from the CITY, pay all amounts due any supplier or subcontractor, whether for labor performed or materials furnished hereunder, when such labor or materials have been included in a requisition submitted by the CONTRACTOR and paid by the CITY. The CONTRACTOR shall include in each of its contracts and subcontracts hereunder a provision requiring each contractor or subcontractor to pay all amounts due any of its own subcontractors, (second tier subcontractors), whether for labor performed or materials furnished, within thirty (30) days after such contractor or subcontractor is paid by the CONTRACTOR an amount that includes payment for labor or materials furnished by such second tier subcontractor. The CITY shall have no obligation to pay directly or to be responsible in any way or under any circumstances for payment to a contractor, subcontractor, employee, agent or representative of the CONTRACTOR.


No progress payment or partial or entire use or occupancy of the Project by the CITY shall constitute an acceptance of Work which does not comply with the Contract Documents. ARTICLE 11. FINAL PAYMENT Final payment and payment of any amounts retained shall not become due until the following conditions precedent have been met: (1) the CITY accepts the Project and approves of all the Work performed hereunder; (2) the CONTRACTOR submits the following documents satisfactory to the CITY (a) certification that all payrolls, bills for materials, labor and equipment, and all other indebtedness connected with the Project, for which the CITY or CITY's property might be liable, have been paid or otherwise satisfied and that there are no claims, obligations, or liens outstanding or unsatisfied for labor, services, materials, equipment or other items performed, furnished or incurred for or in connection with the Work; (b) written consent of surety, if any, to final payment; (c) a certificate that insurance required by the Contract Documents is to remain in force for the required period of time following completion of the Work; (d) a satisfactory two (2) year maintenance bond posted with the CITY insuring the Project for a period of two (2) years from the date of final completion; (e) all required manufacturers' certification that all products and materials have been properly installed and/or incorporated into the Project and issuance of all applicable manufacturers' warranties for same; (f) any other information and documentation establishing payment or satisfaction of all outstanding obligations, to the extent and in such form as may be designated by the CITY, such as, by way of example only, receipts, releases and waivers of liens, including the execution and delivery by the CONTRACTOR, in a form satisfactory to the CITY, of a general release running to and in favor of the CITY; (g) all required Certified Payrolls acceptable to the State of Connecticut Department of Labor; and (h) all Change Orders with sufficient backup/documentation acceptable to the CITY. Should any claim be made or other obligation arise after final payment is made, the CONTRACTOR shall refund to the CITY all expenses paid by the CITY to satisfy, discharge or defend against any such claim, obligation or lien or any action brought or recovered thereon and all costs and expenses, including legal fees and disbursements, incurred in connection therewith. If the CONTRACTOR cannot, for reasonable cause not of its own fault, furnish any such information or documentation required by the CITY, the CONTRACTOR may furnish a bond satisfactory to the CITY promising to indemnify the CITY against any Project related, outstanding obligation. If any lien remains unsatisfied after final payments are made by the CITY, the CONTRACTOR shall reimburse the CITY for moneys the CITY may be compelled to pay in discharging such lien, including all costs and reasonable attorneys' fees.


Final payment being tendered by the CITY shall constitute a waiver of claims by the CITY except those arising from:

A. unsettled liens;

B. faulty or defective Work or materials; C. failure of the Work or materials to comply with requirements of the Contract Documents; or D. terms of special warranties provided by the CONTRACTOR,its suppliers, or its subcontractors, or within the Contract Documents.

E. claims arising after the authorization of any payment.

Acceptance by the CONTRACTOR, or anyone claiming by or through it, of any interim or final payment hereunder shall constitute and operate as a release of the CITY from any and all claims of any liability or responsibility to the CONTRACTOR for anything done to, furnished for, relating to or in connection with the Project hereunder, and for any act, neglect, default on the part of the CITY or any of its officers, agents, or employees unless the CONTRACTOR serves a detailed and verified statement of claim upon the CITY prior to the acceptance of such payment. Such statement shall specify the items and details upon which the claim is based and any claim shall be limited to such items. The CONTRACTOR's refusal to accept the final payment as tendered shall constitute a waiver of any right to interest thereon. ARTICLE 12. FINAL ACCEPTANCE OF WORK When, in the opinion of the Director, the CONTRACTOR has fully performed all the required Work under this Contract and any Change Orders issued for the Project to the CONTRACTOR, the Director shall recommend the acceptance of the Work so completed. If the recommendation is accepted, the CITY shall thereupon notify the CONTRACTOR in writing of such acceptance, and copies of such acceptance shall be sent to other interested parties. However, the CITY has the right to reject the whole or any portion of the Work should it be found or known to be inconsistent with the terms of the Contract Documents or otherwise improper. All certifications upon which partial payments may have been made, being merely estimates, are subject to correction in the final determination or upon final payment. ARTICLE 13. SAFETY The CONTRACTOR agrees that it is responsible for preventing accidents and ensuring safety of all persons engaged in the Project or in the vicinity of the Work including members of the general public. The CONTRACTOR shall comply with all laws, ordinances, rules, regulations, codes, standards, orders, notices and requirements concerning safety


applicable to the Work, including, among others, the Federal Occupational Safety and Health Act of 1970, as amended, and all standards, rules, regulations and orders which have been or shall be adopted or issued thereunder, and with all safety standards established during the progress of the Work. The CONTRACTOR shall at all times provide sufficient, safe and proper facilities for the inspection of the Work by the CITY and its authorized representatives in the field, at shops or at any other place where materials or equipment for the Work are in the course of preparation, manufacture, treatment or storage. The CONTRACTOR shall, immediately upon receiving written notice from the CITY, stop any part of the Work which is deemed unsafe and proceed to take down all portions of the Work and remove all materials whether worked or unworked, that may be noted as unsound, defective or improper or as in any way failing to conform to this Contract or the Plans, Specifications or other Contract Documents. The CONTRACTOR, at its own cost and expense, shall replace the same with proper and satisfactory Work and materials and make good all Work damaged or destroyed by or as a result of such unsound, defective, improper or nonconforming Work or materials or by the taking down, removal or replacement thereof. The CONTRACTOR agrees that it shall not have nor make any claim for costs, damages, delays or extensions of time arising out of such stoppages. Should the CONTRACTOR neglect to take such corrective measures, the CITY may do so at the cost and expense of the CONTRACTOR and may deduct the cost thereof from any payments due or to become due to the CONTRACTOR. Notwithstanding the foregoing, CONTRACTOR shall at all times be responsible for ensuring the safety of all persons and property at the Site, regardless of any action or failure to act on the part of the CITY. Nothing set forth herein, nor any action or failure to act by the CITY, shall relieve the CONTRACTOR of its obligations and responsibilities with regard to safety and safeguarding of the Site and all persons and property thereon or adjacent thereto. ARTICLE 14. LABOR AND EMPLOYMENT REGULATIONS Pursuant to Connecticut General Statutes, Section 31-52a, the following provision shall be incorporated into this Contract and each subcontract hereunder insofar as this Contract or any such subcontract concerns a public works project, including, but not limited to, construction, remodeling or repairing of any public facility or structure (except public buildings covered by Section 31-52), site preparation or improvement, appurtenances or highways, or the preparation or improvement of any land or waterway on or in which a structure is situated or to be constructed:

In the employment of mechanics, laborers or workmen to perform the work specified herein, preference shall be given to residents of the State who are, and continuously for at least six (6) months prior to the date hereof have


been, residents of this State, and if no such person is available then to residents of other states. Nothing herein shall abrogate or supersede any provision regarding residence requirements in a collective bargaining agreement to which the CONTRACTOR is a party.

The CONTRACTOR shall include the foregoing provision in all subcontracts entered into pursuant to this Contract or related to this Project. Pursuant to Connecticut General Statutes, Section 31-53, the following provision shall be incorporated into this Contract and each subcontract hereunder for work relating to the construction of a public works project where the total cost of all work to be performed in connection with such project is Four Hundred Thousand Dollars ($400,000.00) or more, and each contract for work relating to the remodeling, refinishing, refurbishing, rehabilitation, alteration or repair of any public works project where the total cost of all work to be performed in connection with such project is One Hundred Thousand Dollars ($100,000.00) or more:

The wages paid on an hourly basis to any mechanic, laborer or workman employed upon the work herein contracted to be done and the amount of payment or contribution paid or payable on behalf of each such employee to any employee welfare fund described in Section 31-53(h) of the Connecticut General Statutes, shall be at a rate equal to the rate customary or prevailing for the same work in the same trade or occupation in the CITY of Norwalk. Any contractor who is not obligated by agreement to make a payment or contribution on behalf of such employees to any such employee welfare fund shall pay to each employee as part of his wages the amount of payment or contribution for his classification on each pay day.

In the event that the CITY determines that any mechanic, laborer or workman employed by the CONTRACTOR or any subcontractor directly on the Site for the Work contemplated hereunder has been or is being paid a rate of wages less than that required to be paid, as stated herein, the CITY may, by written notice to the CONTRACTOR, terminate the CONTRACTOR's right to proceed with the Work hereunder or such part of the Work for which there has been a failure to pay the required wages. In the event of such termination, the CITY may prosecute the Work to completion by contract or otherwise and the CONTRACTOR and its sureties shall be liable to the CITY for all costs incurred thereby in excess of the compensation to be paid under this Contract. ARTICLE 15. RIGHT TO SUSPEND WORK OR TERMINATE CONTRACT The CITY may at any time and for any reason terminate this Contract for convenience by written notice specifying the termination date,


which shall be not less than seven (7) days from the date such notice is given. In the event of such termination for convenience, the CONTRACTOR shall be paid an amount that shall compensate the CONTRACTOR for the portion of the Work satisfactorily performed prior to termination. Such amount shall be fixed by the CITY after consultation with the CONTRACTOR, and shall be subject to audit by the CITY's Comptroller. In the event the CITY determines that there has been a material breach by the CONTRACTOR of any of the terms of the Contract; the CONTRACTOR refuses or has failed to perform the Work or any part thereof in a timely, professional and diligent manner as will ensure its completion in accordance with the requirements hereof; the CITY determines that the Work hereunder is not being performed according to the Contract; the CONTRACTOR at any time refuses or neglects to supply a sufficient number of skilled workers or materials of the proper quality and quantity; the CONTRACTOR fails in any respect to prosecute the Work with promptness and diligence; the CONTACTOR causes by any act or omission the stoppage, delay, or damage to the Work of any other contractors or subcontractors on the Project; the CONTRACTOR fails in the performance of any of the terms and provisions of this Contract or of the other Contract Documents; there is filed by or against the CONTRACTOR a petition in bankruptcy or for an arrangement or reorganization; or the CONTRACTOR becomes insolvent or is adjudicated bankrupt or go into liquidation or dissolution, either voluntarily or involuntarily or under a court order, or makes a general assignment for the benefit of creditors, or otherwise acknowledges insolvency, the CITY has the right, power and authority to terminate this Contract for cause upon providing the CONTRACTOR three (3) days written notice. Said notice is provided for the purposes of allowing the CONTRACTOR the opportunity to wind down its operations and is not intended to provide the CONTRACTOR with the opportunity to cure. In the event the CITY terminates the Contract for cause, the City may proceed with the Project in such manner and by such process as it determines to be in the best interest of the Project. Furthermore, the CONTRACTOR shall not be entitled to receive any further payment under this Contract until the Work shall be wholly completed to the satisfaction of the CITY, as evidenced by written acceptance signed by the Director. Conversely, the CONTRACTOR shall be obligated to pay the CITY the cost of completing the Work to the satisfaction of the CITY and of performing and furnishing all labor, services, materials, equipment, and other items required therefor, but also all losses, damages, costs and expenses, (including legal fees and disbursements incurred in connection with reprocurement, in defending claims arising from such default and in seeking recovery of all such costs and expenses from the CONTRACTOR and/or its surety), and disbursements sustained, incurred or suffered by reason of or resulting from the CONTRACTOR's default. If such costs and expenses and other charges exceed the amount otherwise due the CONTRACTOR, such excess amount shall be charged to and promptly paid by the CONTRACTOR to the CITY. In computing the amounts chargeable to the CONTRACTOR, the CITY shall


not be held to a basis of the lowest prices for which the completion of the Project or any part thereof might have been accomplished, but the CONTRACTOR shall be liable for all sums actually paid or expenses actually incurred in affecting prompt completion of the Project hereunder. The rights described herein are in addition to any other rights and remedies provided by law. The CITY also shall have the right to suspend the CONTRACTOR’s performance under this Contract at any time and for any reason that the CITY deems in its best interest. Should the CITY reactivate the performance of the Project, in whole or in part, within one (1) year from the time of suspension, any fees paid to the CONTRACTOR pursuant to this Contract shall be applied as payment on the fees as set forth in the Contract at the time of reactivation, and payment for all remaining work shall be made in accordance with this Contract without adjustment. Should reactivation occur after a period of suspension exceeding one (1) year but not sooner, the CONTRACTOR and the CITY may renegotiate the Contract based upon current conditions or the CONTRACTOR or the CITY may unilaterally elect to terminate the Contract. Termination or suspension under this section shall not give rise to any claim against the CITY for damages or compensation in addition to that provided hereunder. ARTICLE 16. INTERPRETATION OF PLANS/SHOP DRAWINGS The Work shall be performed and furnished under the direction and to the satisfaction of the CITY and, where appropriate, its Architect or Engineer. The CONTRACTOR shall be responsible for identifying any ambiguity in, or difference in interpretation of the plans, specifications or other Contract Documents, or between or among any of them, and immediately submitting the issue to the CITY, which will transmit the same to the responsible professional designer (i.e., Professional Engineer or Architect) who shall resolve the same. Any decision in relation thereto shall be final and conclusive upon the parties. The CITY will furnish to the CONTRACTOR any additional information and Plans as may be prepared to further describe the Work and the CONTRACTOR shall conform to and abide by the same. Notwithstanding the dimensions on the Plans, Specifications and other Contract Documents it shall be the obligation and responsibility of the CONTRACTOR to take such measurements as will insure the proper matching and fitting of the Work covered by this Contract with contiguous work. The CONTRACTOR shall prepare and submit to the Director such shop drawings as may be necessary to describe completely the details and construction of the Work. Approval of such shop drawings shall not relieve the CONTRACTOR of its obligation to perform the Work according to the Plans, Specifications, the Special Conditions, Addenda and all other Contract Documents, nor of its responsibility for the proper


matching and fitting of the Work with contiguous work and the coordination of the Work with other work being performed on the Site, which obligation and responsibility shall continue until completion and acceptance of the Project. The CONTRACTOR's submission of a shop drawing shall constitute the CONTRACTOR's representation that it has reviewed the submission for accuracy and compliance with all Contract Documents and that, wherever engineering is required to be performed, same has been performed by a qualified and licensed engineer which shall have responsibility therefor. Should the proper and accurate performance of the Work hereunder depend upon the proper and accurate performance of other work not covered by this Contract, the CONTRACTOR shall carefully examine such other work, determine whether it is in fit, ready and suitable condition for the proper and accurate performance of the Work hereunder, use all means necessary to discover any defects in such other work, and before proceeding with the Work hereunder, report promptly any such improper conditions and defects to the CITY in writing and allow the CITY a reasonable time to have such improper conditions and defects remedied. ARTICLE 17. REJECTED WORK AND MATERIAL In the event the CITY finds that the materials furnished, the finished Project or the Work performed hereunder by the CONTRACTOR, for any reason, does not conform with the requirements of the Contract Documents including any performance and Project specifications and has resulted or will result in an inferior or unsatisfactory product, the materials or Work shall be removed and replaced or otherwise corrected, to the satisfaction of the CITY, by and at the expense of the CONTRACTOR. The CONTRACTOR agrees that it shall at once remove from the Site at its own expense all Work or material which may be rejected by the CITY and replace the same with Work or material satisfactory to the CITY. All Work shall be in a first class and satisfactory condition at the time of final acceptance. ARTICLE 18. LAWS, PERMITS, AND LICENSES The CONTRACTOR shall observe all Federal, State, and local laws and regulations and shall procure all necessary licenses and permits, pay all charges and fees, and give all notices necessary and incident to the due and lawful prosecution of the Work hereunder without any additional charge or expense to the CITY. CONTRACTOR shall be responsible for and shall correct, at its sole cost and expense, any violation thereof resulting from or in connection with the performance or failure to perform the Work.


The CONTRACTOR shall at any time upon demand furnish such proof as the CITY may require showing such compliance and the correction of such violations. The CONTRACTOR agrees to save harmless and indemnify the CITY, its officers and employees, from and against any and all loss, injury, claims, actions, proceedings, liability, damages, fines, penalties, costs and expenses, including legal fees and disbursements, caused or occasioned directly or indirectly by the CONTRACTOR's failure to comply with any of said laws, ordinances, rules, regulations, standards, orders, notices or requirements or to correct such violations thereof in connection with the performance of Work. ARTICLE 19. EQUAL EMPLOYMENT OPPORTUNITY The CONTRACTOR agrees and warrants that in the performance of this Contract it will not discriminate or permit discrimination in any manner prohibited by the laws of the United States or of the State of Connecticut against any person or group of persons on the grounds of race, color, religious creed, age, marital status, national origin, ancestry, gender, sexual orientation, mental retardation or physical disability, including, but not limited to, blindness, unless it is shown by the CONTRACTOR that such disability prevents performance of the work involved. The CONTRACTOR further agrees to take affirmative action to insure that applicants with job-related qualifications are fairly employed and that employees are treated in a fair and nondiscriminatory manner.

The CONTRACTOR agrees to provide the Commission on Human Rights and Opportunities with such information requested by the Commission concerning its employment practices and procedures. The CONTRACTOR will cause the foregoing provisions to be inserted in all subcontracts for any of the Work covered by this Contract so that such provisions will be binding upon each subcontractor. ARTICLE 20. SUCCESSORS AND ASSIGNS This Contract shall bind the successors, assigns and representatives of the parties hereto. Notwithstanding the foregoing, this Contract may not be assigned by the CONTRACTOR nor shall the CONTRACTOR's rights, title or interest herein or hereto be assigned, transferred, conveyed, sublet, or disposed of without the previous written consent of the Director. ARTICLE 21. RESPONSIBILITY FOR THE SITE At all times throughout the performance of this Contract and until final acceptance of the Work hereunder, the CONTRACTOR shall be in control of and responsible for the Site and for any loss or damage to the Work to be performed and furnished under this Contract, however caused. This shall include responsibility for loss of or damage to materials, tools, equipment, appliances or other personal property owned, rented or used by the CONTRACTOR or anyone employed by it in


the performance of the Work, however caused. Accordingly, the CONTRACTOR shall, at its own cost and expense, (1) keep the Site free at all times from all waste materials, packaging materials and other rubbish accumulated in connection with the execution of its Work, (2) clean and remove from its own Work and from all contiguous work of others any soiling, staining, mortar, plaster, concrete or dirt caused by the execution of its Work and make good all defects resulting therefrom, (3) at the completion of its Work in each area, perform such cleaning as may be required to leave the area "broom clean", and (4) at the entire completion of its Work, remove all of its tools, equipment, scaffolds, shanties and surplus materials. Should the CONTRACTOR fail to perform any of the foregoing to the CITY's satisfaction, the CITY shall have the right to perform and complete such Work itself or through others and charge the cost thereof to the CONTRACTOR. ARTICLE 22. INSURANCE The CONTRACTOR agrees to obtain at its own cost and expense all insurance required by the attached Insurance Rider and to keep the same in continuous effect for a period of two (2) years following the date on which the Director indicates the termination of the CONTRACTOR's responsibilities hereunder. Before commencing the Project, the CONTRACTOR shall furnish the CITY's Corporation Counsel a certificate of insurance, and shall thereafter provide renewal certificates, as appropriate, evidencing such coverage written by a company or companies acceptable to the CITY. Each insurance certificate shall be endorsed to name the City of Norwalk as an additional insured party and shall provide that the insurance company providing coverage shall notify the CITY by certified mail at least thirty (30) days prior to the effective termination of or any change in the policy or policies coverage. No change in the coverage provided hereunder shall be made without the prior written approval of the Director. ARTICLE 23. INDEMNIFICATION The CONTRACTOR expressly agrees to at all times indemnify, defend and save harmless the CITY of Norwalk and its respective officers, agents and employees, on account of any and all demands; claims; damages; losses; litigation; financial costs and expenses, including counsel's fees; and compensation arising out of personal injuries (including death), any damage to property, real or personal, and any other loss, expense or aggrievement directly or indirectly arising out of, related to or connected with the Project and the Work to be performed hereunder by the CONTRACTOR, its employees, agents, subcontractors, material suppliers, or anyone directly or indirectly employed by any of them. The CONTRACTOR shall and does hereby assume and agree to pay for the defense of all such claims, demands, suits, proceedings and litigation. The provisions of this paragraph shall survive the expiration or early termination of this Contract; shall be separate and independent of any other provision or requirement of this


Contract; and shall not be limited by reason of any insurance coverage provided hereunder. The CITY may withhold from any payment due or to become due to the CONTRACTOR an amount sufficient in its judgment to protect and indemnify the CITY, its officers, agents, servants and employees from and against any and all such claims and liabilities described above. Nothing in this provision, or elsewhere in this Contract, shall be deemed to relieve the CONTRACTOR of its duty to defend the CITY or any Indemnified Party, as specified in this Contract, pending a determination of the respective liabilities of the CONTRACTOR, the CITY, or any Indemnified Party, by legal proceeding or agreement. In furtherance to but not in limitation of the indemnity provisions in this Contract, CONTRACTOR hereby expressly and specifically agrees that its obligation to indemnify, defend and save harmless as provided in this Contract shall not in any way be affected or diminished by any statutory or constitutional immunity it enjoys from suits by its own employees or from limitations of liability or recovery under workers' compensation laws. ARTICLE 24. SUBCONTRACTING AND ASSIGNMENTS The CONTRACTOR shall not subcontract any portion of the Work to be performed hereunder unless the prior written consent of the Director is given for both the Work to be subcontracted and the subcontractor to perform the same. In the event that the CITY approves of the hiring of subcontractors or subconsultants to pursue the Project, the CONTRACTOR agrees to cooperate as fully as possible with the CITY and any and all such subcontractors and subconsultants in the interests of the Project. The CONTRACTOR shall be as fully responsible to the CITY for the acts and omissions of its subcontractors and subconsultants as it is for the acts and omissions of its direct employees and shall require any subcontractor or subconsultant approved by the CITY to agree in a written contract to observe and be bound by all obligations and conditions of this Agreement to which CONTRACTOR is bound hereby including the requirements regarding insurance and indemnification. Each subcontract agreement shall preserve and protect the rights of the CITY and the Project Architect/Design Engineer, under the Contract Documents with respect to the Work to be performed by the subcontractor so that the subcontracting thereof will not prejudice such rights, and shall allow the subcontractor, unless specifically provided otherwise, the benefits of all rights, remedies and redress against the CONTRACTOR that the CONTRACTOR has against the CITY pursuant to the Contract Documents.


Nor shall CONTRACTOR assign, sell, transfer, delegate or encumber any rights, duties or obligations arising under this Contract including, but not limited to, any right to receive payments hereunder, without the prior written consent of the CITY in its sole discretion. The giving of any such consent to a particular assignment shall not dispense with the necessity of such consent to any further or other assignments. In the event CONTRACTOR assigns, sells, encumbers or otherwise transfers its rights to any monies due or to become due under this Contract as security for any loan, financing or other indebtedness (herein "Assignment"), notification to the CITY of such Assignment must be sent by certified mail, return receipt requested, and the Assignment shall not be effective as against the CITY until the CITY provides its written consent to such Assignment. CONTRACTOR agrees that any such Assignment shall not relieve the CONTRACTOR of any of its agreements, duties, responsibilities or obligations under this Contract and the other Contract Documents and shall not create a contractual relationship or a third party beneficiary relationship of any kind between the CITY and assignee or transferee. CONTRACTOR further agrees that all of the CITY's defenses and claims arising out of this Contract with respect to any Assignment are reserved unless expressly waived in writing by a duly authorized representative. CONTRACTOR hereby agrees to indemnify, defend and hold harmless the CITY from and against any and all loss, cost, expense or damages that the CITY has or may sustain or incur in connection with such Assignment. ARTICLE 25. WARRANTY The CONTRACTOR hereby warrants to the CITY that all of the Work shall be in conformance with the Plans, Specifications, and all Contract Documents and shall be of good quality and free from any faults and defects. The CONTRACTOR shall remove, replace and/or repair at its own expense and at the convenience of the CITY any portion of the Work, materials or equipment which, at any time up until two (2) years from the date of final acceptance of the Work hereunder, the Architect or the CITY shall condemn as unsound, defective or improper or as in any way failing to conform to this Contract or the plans, specifications or other Contract Documents, and the CONTRACTOR, at its own cost and expense, shall replace the same with proper and satisfactory Work, materials and/or equipment. Without limiting the generality of the foregoing, the CONTRACTOR warrants to the CITY that all materials and equipment furnished under this Contract will be of first class quality and new, unless otherwise required or permitted by the other Contract Documents; that the Work performed and materials used pursuant to this Contract will be free from any defects and that the Work will conform with the requirements of the Contract Documents. Work not conforming to such requirements,


not of the prescribed quality, or not capable of meeting the CITY's performance specifications, including substitutions not properly approved and authorized, shall be considered defective and must be removed and replaced by CONTRACTOR at its own cost and expense. All warranties contained in this Contract and in the Contract Documents shall be in addition to and not in limitation of all other warranties or remedies required and/or arising pursuant to applicable law. ARTICLE 26. NOTICE OF CLAIMS

Claims by either party must be in writing and sent within thirty (30) days following the occurrence of an event giving rise to the claim or within thirty (30) days after the claimant first acquires knowledge of or information concerning the claim, whichever occurs later to the extent that such knowledge or information could not have been reasonably obtained earlier. Claims must be made in writing and sent to the other party at the address(es) listed herein and shall describe the nature of the claim, the events or circumstances that gave rise to the claim with reasonable detail, and the amount thereof to the best of the claimant's information. ARTICLE 27. LIQUIDATED DAMAGES It is understood by the parties that timely completion of the Project is essential. Failure of the CONTRACTOR to complete the Project by the date stated herein will result in the CITY and the public incurring damages, additional costs and inconveniences that would be impossible or extremely difficult to accurately quantify at the time. Therefore, the parties agree that, if the CONTRACTOR fails to satisfactorily complete the Project hereunder within the time specified or within any extension of time that may have been allowed, there shall be deducted from any monies due or that may become due the CONTRACTOR, the sum of ONE HUNDRED DOLLARS ($500.00) for each and every calendar day, including Saturdays and legal holidays, that the Project remains incomplete in accordance with Article 5 of this Agreement. This sum shall not be imposed as a penalty, but as liquidated damages due the CITY from the CONTRACTOR by reason of the damages incurred, inconvenience and additional costs and expenses to the public together with other problems suffered as a result of any such delay thereby occasioned. ARTICLE 28. GENERAL PROVISIONS A. This Contract shall be deemed binding only to the extent that sufficient funds are available and appropriated to the CITY for payment in accordance with the terms hereof and no liability on account of this Contract shall be incurred by the CITY beyond such moneys as are properly made available and appropriated for the Project.


B. The relationship of the CONTRACTOR to the CITY is that of an independent CONTRACTOR. The CONTRACTOR covenants and agrees that it will conduct itself consistent with such status; that it will neither hold itself nor any of its employees or agents out as nor claim to be an officer, agent, or employee of the CITY by reason hereof; and that it will not, neither for itself nor on behalf of any of its employees, agents, or subcontractors, by reason hereof, make any claim, demand or application to or for any right or privilege applicable to an officer or employee of the CITY, including, but not limited to, workers' compensation coverage, unemployment insurance benefits, social security coverage, or retirement membership or credit. C. The CONTRACTOR hereby certifies that neither it nor its principals are presently debarred, suspended, proposed for debarment, declared ineligible, or voluntarily excluded from participation in this transaction by any federal or state department or agency. Should the CONTRACTOR be unable to certify the above statement, it shall attach a certified statement explaining such to this Contract. The CONTRACTOR further agrees to include the foregoing certification in any subcontract or purchase order which it may enter into in furtherance of the Work contemplated hereunder. D. No member of the governing body of the CITY, and no other officer, employee, or agent of the CITY, shall have any personal interest, direct or indirect, in this Contract, except as permitted by the Code of Ethics of the City of Norwalk; and the CONTRACTOR covenants that no person having such interest shall be employed in the performance of this Contract. E. This Contract shall be construed in accordance with the laws of the State of Connecticut, and any action at law in connection herewith shall be brought in the Superior Court of the State of Connecticut, Judicial District Stamford/Norwalk. F. The CONTRACTOR shall comply with all applicable laws, ordinances and codes of any governmental body having jurisdiction over any matter related to this Agreement or the services to be performed hereunder, and shall commit no trespass on any private property in performing any of the Work embraced herein. G. This Contract incorporates all the understandings of the parties hereto, supersedes any and all agreements and negotiations reached and all commitments made by the parties prior to the execution of this Contract, whether oral or written, and shall not be released, amended or modified in any way unless by a written instrument signed by the parties hereto.


H. If any provision of this Contract is held invalid, the balance of the provisions of this Contract shall not be affected thereby if the balance of the provisions of this Contract would then continue to conform to the requirements of applicable laws. I. Each and every provision and clause required by law to be inserted in this Contract shall be deemed to be inserted herein and the Contract shall be read and enforced as though such provisions and clauses were included herein. If, through mistake or otherwise, any such provision is not inserted or is not correctly inserted, then upon the written consent of the parties, this Contract shall forthwith be physically amended to make such insertion. J. All notices of any nature referred to in this Contract shall be in writing and sent by registered or certified mail, postage prepaid, to the respective addresses set forth below or to such other addresses as the respective parties hereto may designate in writing: To the City: ___________________ ___________________ City Hall, P. O. Box 5125

To the Contractor: ____________________ ____________________ ____________________ K. The CONTRACTOR represents to the CITY as follows:

That the CONTRACTOR is a legally existing corporation under the laws of its respective states of incorporation and has not previously filed, nor is presently contemplating filing, nor has received notice of a petition of, nor contemplates receiving notice of a petition of, bankruptcy, liquidation, receivership or any other action for the protection of creditors or debtors;

That the CONTRACTOR has the financial resources to perform this Contract and that it is not the subject of any litigation or action, pending or threatened, regarding this Contract or which, if resulting in an adverse decision, would affect its ability to perform its duties under this Contract;

Automobile Liability: With respect to each owned, non-owned, or hired vehicles the Contractor shall carry Automobile Liability insurance providing One Million Dollars ($1,000,000.00) coverage per accident for bodily injury and property damage.

Work performed by the subcontractors. All Certificates of Insurance shall be provided to the City's Corporation Counsel as required herein. Aggregate Limits: Any aggregate limits must be declared to and be approved by the City. It is agreed that the Contractor shall notify the City whenever fifty percent (50%) of the aggregate limits are eroded during the required coverage period.

3.0 Procedure 3.1 Examination

A. Verify that the surfaces and site conditions are ready to receive work.

B. Verify that the deck is supported and secured.

C. Verify that the deck is clean and smooth, free of depressions, waves, or projections, and properly sloped to drains, valleys, eaves, scuppers or gutters.

D. Verify that the deck surfaces are dry and free of ice or snow.

E. Verify that all roof openings or penetrations through the roof are solidly set, and

that all flashings are tapered. 3.2 Substrate Preparation

A. Precast Concrete Decks 1. Precast concrete decks manufactured with solid planks constructed of steel

reinforced Portland cement and solid aggregate. 2. Contractor must determine the fitness of deck for direct membrane

application. 3. If the deck is wet, it must be allowed to dry. 4. Inform Architect of any deformed/deteriorated panel. 5. Joints must be filled with a masonry grout to correct imperfections between

slabs and feathered to provide a slope not greater than 1/4 “ per foot (2.1 cm/m), for non-insulated assemblies or 1/8” per foot (1.0 cm/m) for insulated assemblies

6. Any depression must be filled with masonry grout and any cracks greater than 1/8” (3 mm) width treated in accordance with the deck manufacturer’s recommendations.

7. If joints cannot be grouted and finished smooth, then a leveling course of lightweight insulating concrete (minimum 2” (5.1 cm) thickness) must be applied. Do not seal joints between the slabs; leave open to permit venting and drying of roof fill from below.

8. When applying roofing or insulation directly to the deck with asphalt, prime with asphalt/concrete primer, ASTM D41, at a rate of 1 gal/square (.4 L/m2) and allow the primer to dry prior to the application of the roofing system. Hold back bitumen at the joints approximately 4”(10.2 cm) to prevent bitumen drippage.

3.3 Installation - General

A. Install roofing system according to all current application requirements in

addition to those listed in this section.

B. When the slope of the roof is ½” per foot or greater, install all plies parallel with the slope of the roof, and install intermediate wood nailers as required for the specific roof slope. Plies must extend over ridges and nailed on 6” centers.

TS-13

C. Start the application of membrane plies at the low point of the roof or at the drains, so that the flow of water is over or parallel to, but never against the laps.

3.4 Air/Vapor Barrier

A. General:

1. Attachments listed below are minimum requirements. Consult the current FM Guide for listings of Factory Mutual approved attachments.

2. All laps, joints, penetrations and projections shall be properly sealed at the vapor retarder level to ensure that it performs as designed.

3. Insulation shall be installed immediately following the application of the vapor retarder to avoid the potential for punctures caused by construction traffic and prolonged exposure to the elements.

4. While specified herein, a Vapor Retarder / Temporary Roof is an optional component of the roof system. Without the Manufacturer’s Contractor Services approval specific to this project, no vapor barrier or temporary roof shall be covered under the terms and conditions of the warranty expressed herein.

5. When a SBS modified bitumen sheet is used as a vapor retarder or temp roof, and insulation is to be torched down, the installed sheet shall be lightly heated with a torch to burn off any polypropylene or polyethylene parting agent that remains.

B. Structural Concrete Deck:

1. Prime the deck with asphalt primer (ASTM D 41) applied at the rate of 1 gal/square (0.41 L/m²).

2. Starting at the low point of the roof, install one ply of vapor barrier as per manufacturer’s requirements.

3.5 Insulation - General

A. Do not apply roof insulation or roofing until all other work trades have completed jobs that require them to traverse the deck on foot or with equipment. A vapor retarder coated lightly with asphalt may be applied to protect the inside of the structure prior to the insulation and final roofing installation. Before the application of the insulation, any damage or deterioration to the vapor retarder must be repaired.

B. Do not install wet, damaged or warped insulation boards.

C. Install insulation boards with staggered board joints in one direction (unless

taping joint). D. Install insulation boards snug. Gaps between board joints must not exceed ¼” (6

mm). All gaps in excess of ¼” (6 mm) must be filled with like insulation material.

E. Wood nailers must be 3-1/2” (8.9 cm) minimum width or 1” (25 mm) wider than metal flange. They shall be of equal thickness as the insulation with a minimum 1” (25 mm) thickness. All nailers must be securely fastened to the deck.

TS-14

F. Do not kick insulation boards into place.

G. Miter and fill the edges of the insulation boards at ridges, valleys and other

changes in plane to prevent open joints or irregular surfaces. Avoid breaking or crushing of the insulation at the corners.

H. Do not install insulation over old lightweight insulating concrete decks without

the use of a vapor retarder. Insulation should not be installed over new lightweight insulating concrete.

I. Cant strips must be installed at the intersection of the roof and all walls,

parapets, curbs, or transitions approaching 90°, to be flashed. They shall be approximately 4” (10.2 cm) in horizontal and 4” (10.2 cm) in vertical dimension. The face of the cant shall have an incline of not more than 45 degrees with the roof.

J. Roof tape, if required over insulation joints, must be laid evenly, smoothly and

embedded in a uniform coating of hot steep asphalt with 4” (10.2 cm) end laps. Care must be taken to assure smooth application of tape, and full embedment of the tape in the asphalt.

K. Do not install any more insulation than will be completely waterproofed each

day.

3.6 Installation of Rigid Insulation w/CR-20 Polyurethane Adhesive

A. Application Temperature:

All surfaces to be bonded must be clean, dry and free from dirt, dust, oil, loose paint, wax or grease, etc. The temperature of the adhesive should be between 70°-95°F (21°-35°C) and the surfaces being bonded should be at 40°F (4°C) or above. Temperatures outside this range may affect bonding range, dispensability and performance of the product.

B. Suggested Equipment:

3MTM 2-Component Spray Polyurethane Foam Applicator and Hose Assembly.

C. Equipment Set Up:

There are two cylinder tanks per system. The system is comprised of an “A” cylinder that is RED and a “B” cylinder that is BLUE. These two cylinders must have matching fill dates to be used together. The cylinders can only be used in the upright position (Never open the valves unless the cylinders are upright). The lids on the boxes are designed to shield the cylinders from direct sunlight and keep the product from getting too hot. For this reason, the box lid should remain closed during use.

TS-15

1) Using the wrench included in the nozzle pack, connect the RED striped hose to the “A” cylinder. 2) Connect the BLACK striped hose to the “B” cylinder. 3) Slowly open the cylinder valves and inspect the connections for any leaks. Tighten if needed. Fully open the valves. 4) Activate the trigger, dispensing into a proper waste receptacle, until all the air is released from the hoses and a good stream of both chemicals is visible through the applicator orifices. 5) Clean residue from the output tips. 6) Attach the mixing nozzle to the applicator. Insert the bottom tab of the nozzle into the bottom slot of the applicator gun. Secure the top latch by pushing towards the back of the applicator until it “snaps” into the locked position.

D. Adhesive Test Spray:

When spraying for the first time, or when starting a new kit, it is recommended to trigger the gun only 1/2 to 3/4 open, until the desired output and spray pattern is achieved. This controllable metering ability is a major advantage of the gun, allowing the user complete control of the flow rate and spray pattern that best fits the application. Apply several test shots on plastic or cardboard before beginning the job. Extremely Important - When spraying is stopped for more than 1 minute, the nozzle should be removed and replaced with a new nozzle. The chemical in the nozzle will begin to cure and will clog the nozzle when spraying has stopped for more than a few minutes. If the trigger is pulled while a clogged nozzle is on the gun, the chemical from the cylinders (which is under pressure!) will be blocked by the clogged nozzle and will cause a “back-up” of chemical into the hoses, which is called a crossover. The gun will no longer dispense chemicals in the right proportions and the CR-20 adhesive will not function properly. This situation can be easily avoided by simply changing nozzle when spraying is stopped for more than 1 minute.

E. Adhesive Application:

To dispense foam, point the applicator’s nozzle at the surface to be sprayed, holding it approximately 20 inches from the surface. Squeeze the trigger and move hand at a speed, which delivers the desired adhesive pattern.

The CR-20 insulation adhesive is applied in rows placed a maximum of 12" OC.

Insulation boards are to be placed immediately on the wet adhesive but not walked into place or compressed into the adhesive until the CR-20 has begun to thicken and started to develop its initial bond. The time involved in this process is contingent on the ambient as well as deck surface temperature. The chart below illustrates the approximate time required prior to walking in or adding ballast to the boards.

After the adhesive has attained its initial bond strength the boards can be “walked-in” and will be compressed to the deck or substrate exhibiting minimal slippage or movement. The boards should be exposed to minimum traffic for at least 10-20 minutes (depending on temperature) after they have been “walked-in-place” to avoid breaking the freshly formed bond.

NOTE: Membranes can be applied once the adhesive has achieved sufficient bond strength to the immediate-ate substrate to which it is adhered. It is recommended that the contractor inspect the installed insulation for proper adhesion and re-adhere any boards and/or corners that are not adequately attached.

NOTE: Boards that will not lay flat due to cupping, warping or crowning, or surface irregularities of the substrate, should have weights placed on the boards until the CR-20 has achieved adequate adhesion to hold the boards in place.

When spaying stops for breaks, lunch or overnight. Repeat the purging procedure in step # 2. VERY IMPORTANT: As the hoses are exposed to the heat of the sun, especially in the summer months, the pressure in the hoses will build up. Purging the hoses for a few seconds prior to spraying relieves the excess pressure and allows the chemical to flow in the proper proportions.

F. Equipment Storage and Re-Use:

1) Turn the cylinder tank valves off. 2) Do not store at temperatures above 100°F (38°C) or below 50°F (10°C). 3) The used nozzle should be left on the gun during storage. 4) Engage the trigger safety lock. 5) Close the supply valves on both “A” and “B” cylinders. Note: The dispensing gun is a disposable unit and is not designed for prolonged storage or continuous re-use. To help extend the storage life, it is recommended to dispense a minimal amount of foam from the gun at least once every seven days to ensure optimum flow of chemical through the hoses. Use of contents within 30 days of initial use is recommended. Make certain valves are in correct position when turning them on and when operating the unit.

G. Re-Use of Applicator Gun After Storage:

1) Before disengaging the trigger safety lock, remove the used nozzle. 2) Check the face of the gun to make sure the outlet ports are clear and the face of the gun is free from dirt, chemical or other debris. 3) If necessary, use a rag to remove any cured foam or chemical from the face of the gun. 4) See Equipment Set Up directions 4-6.

H. Disposal Procedures:

1) Do not puncture or incinerate cylinder tanks while under pressure. 2) After cylinders are empty, they must be vented. CAUTION: Tanks will still be under pressure. Eye protection and impervious gloves MUST be worn during the procedure. With tank valve in opposite position of use, slowly open the tank valve, point tank AWAY from face and allow excess chemical to drain into a lined trashcan and pressure to completely vent.

TS-17

CAUTION: Empty tank could contain potential vapor toxicity hazard. Provide adequate ventilation or respiratory protection (consult MSDS). 3) Once cylinder is empty and vented, carefully puncture the friable disc on the top of the cylinder. 4) DISPOSE OF EMPTY CYLINDERS AND EXCESS CHEMICAL ACCORDING TO APPLICABLE FEDERAL, STATE AND LOCAL REGULATIONS.

3.7 Installation of HD Gypsum Primed Roof Boards

A. Application:

Primed roof boards should not be subjected to abnormal or excessive loads or foot traffic, such as, but not limited to, use on plaza decks or under steel-wheeled equipment that may fracture or damage the panels. Provide suitable roofing system protection when required.

Primed roof board is the preferred substrate for torch application. However, the product must be dry prior to commencing installation of torch application.

• Ensure product is dry. Ensure proper torching technique.

• Limit the heat to the roof board. Maintain a majority of the torch flame directly on the roll.

• When torching to primed roof boards, field priming should not be required.

C. Installation:

1. Apply only as many primed roof boards as can be covered by a roof membrane system in the same day.

2. Primed roof boards of any thickness do not require gapping when used as a cover board.

3. Board edges and ends should be butted in typical installations. Gapping is only required for ¼” primed panels applied directly on a steel deck.

4. Follow procedures under 3.6 above to use same CR-20 polyurethane adhesive to install all gypsum roof boards.

C. Moisture Management:

1. Weather conditions, dew, leaks, application temperatures and techniques may cause adverse effects with roofing systems. All components used in roofing systems, including primed roof boards, must be protected from exposure to moisture before, during and after installation.

2. To ensure that the primed roof boards remain dry prior to installation, the materials must be properly handled upon receipt.

3. Remove the plastic packaging from all products immediately upon receipt of delivery. Failure to remove the plastic packaging may result in entrapment of condensation or moisture, which may cause application problems. This factory packaging is intended to provide temporary moisture protection during transit only and is not intended to provide protection during storage after delivery.

TS-18

4. All boards stored outside must be stored level and off the ground and protected by a breathable waterproof covering. Provide means for air circulation around and under stored bundles of roof boards. Use adequate supports to keep the bundles flat, level, and dry.

5. Moisture can cause blisters to form during hot mopping or torching to any substrate. Because roof boards are relatively dense, any excess moisture will typically vaporize and travel upward into the interface between the membrane and substrate rather than dissipating within the board. In fully adhered single ply or cold mastic bitumen systems, the evaporation of solvents may be restricted and may cause solvent blisters.

6. Care should also be taken during installation to avoid the accumulation of moisture in the system. Primed roof boards must be covered the same day as installed. Avoid application of roof boards during rain, heavy fog and any other conditions that may deposit moisture on the surface, and avoid the overuse of non-vented, direct-fired heaters during winter months. When roofing systems are installed on new poured concrete or lightweight concrete decks or when re-roofing over an existing concrete deck, a vapor barrier should be installed above the concrete to limit the migration of water from the concrete into the roof assembly.

7. Care must be taken after installation to avoid and properly manage leaks and other water accumulation. Moisture vapor movement by convection must be eliminated, and the flow of water by gravity through imperfections in the roof system must be controlled. After a leak has occurred, no condensation on the upper surface of the system should be tolerated, and the water introduced by the leak must be dissipated to the building interior in a minimum amount of time

3.8 Interply Sheets –

A. Three ply interply application: Install starter strips of 13 1/8” (33.3 cm), 26 1/4” (66.7 cm) and 39 3/8” (100.0 cm) widths and follow with a second full 39 3/8” (100.0 cm) width sheet with a maximum 11 1/8” (28.3 cm) exposure, applied shingle style. Lap felts 2615/16” (68.4cm) with a 127/16” (31.6 cm) exposure and lap 6”(15.2 cm) at ends. Stagger adjacent end laps a minimum of 18” (45.7 cm).

3.9 Ply / Cap Sheet -

A. The surface over which the membrane is to be installed must be clean, smooth, dry and prepared in accordance with article 3.02 “Substrate Preparation”. Do not apply membrane directly to a fresh asphalt glaze or flood coat, or over base plies with excessive asphalt mopping bleed out at laps.

B. For slopes 3/4 “ per foot (6.2 cm per meter) and over, membrane must be run

parallel to the roof slope and back nailed in accordance with manufacturer’s steep slope application requirements. On slopes less than 3/4” per foot (6.2 cm per meter), install cap sheet perpendicular to the slope.

TS-19

C. Never apply membrane by any method except welding with a propane torch or other equipment specifically designed for application of torchable modified bitumen.

D. The coiled membrane must be unrolled approximately 10 ft. (3 meters), and aligned. The propane torch flame is then applied uniformly across the exposed back surface of the membrane and lap areas until the compound reaches the proper application temperature and exhibits a slight sheen. A complete burn-off of release films where present on the underside of the rolls, membrane selvage edges or both surfaces is necessary. Avoid overheating which may result in damage to or improper adhesion of the membrane. (The flame should be moved from side to side in the shape of an “L”, applying about 75% of the heat to the membrane and 25% to the substrate or underlying plies including the lap area of the previously installed courses.) The membrane is slowly unrolled as heat is applied to ensure proper adhesion. When complete, re-roll the opposite end of the membrane and install in the same manner.

E. A minimum 3/8” (10 mm) bitumen flow-out must be obtained at all seam areas.

Dry laps are not acceptable. To ensure the proper 3/8” (10mm) flow of bitumen at the seam areas, a roller may be used. Roller application should follow behind the torch no more than 4 ft. (1.2 m) nor less than 3 ft. (0.91 m) to be sure that the membrane will be at the proper temperature to produce proper flow. Hand rollers or “walking-in the seam” methods are also acceptable. Check all seams for full and uniform adhesion. Un-adhered seams must be lifted with a heated trowel and resealed by lightly torching the seam area.

F. Broadcast matching granules into the modified bitumen bleed out at seams while

hot to enhance the finished appearance of the membrane. G. All end laps must be staggered a minimum of 18” (45.7 cm) so that no adjacent

end laps coincide. If end laps fall in line or are not staggered the proper distance, a full width of membrane must be installed over the end laps. End laps, flashing sheets and other seams formed over granule surfaces require pre-heating of the top surface of the underlying granule surface membrane to a point where the granules just begin to sink into, and the modified bitumen compound comes up through the granules to ensure proper seam construction and adhesion.

H. All laps must be parallel or perpendicular to the slope of the roof such that the

flow of water is never against the lap. I. Interply and cap sheet application: Over the base sheet or approved substrate,

install 13 1/8” (33.3 cm), 26 1/4” (66.7 cm) and 39 3/8” (100.0 cm) width membrane starter plies and follow with a second full 39 3/8” (100.0 cm) width granule surfaced sheet applied shingle style. Lap plies 3” (7.62 cm) on sides and 6”(15.2 cm) at ends. Stagger adjacent end laps a minimum of 18” (45.7 cm).

TS-20

J. Membranes must not be applied during adverse weather or without precautionary measures in temperatures below 45ºF (7.2ºC). Contact Manufacturer’s Contractor Services for details.

3.10 Bituminous Base Flashings

A. Install base flashing as detailed over all cant strips, horizontal to vertical transitions, roof edges and roof penetrations. Flashings are to be secured in accordance with current manufacturer’s application guidelines.

B. Nailable curbs and walls must be covered with a layer of approved base sheet or

backer ply fastened 8” (20.3 cm) o.c. in all directions with approved fasteners. All vertical laps shall be 4” (10.2 cm). Base sheet or backer ply must extend out onto the field of the roof as shown on the applicable construction detail.

C. Prime all metal and masonry surfaces with asphalt primer, and allow adequate

drying time prior to adhering flashing plies. D. Backer plies installed over masonry or other non-nailable substrates must be cut

into manageable lengths to ensure adequate adhesion to the cant strip and vertical surfaces without excessive voids. All vertical laps shall be 4” (10.2 cm). Backer plies shall extend onto the field of the roof as shown on the applicable construction detail.

E. The finished ply of base flashing shall be run vertically to provide a selvage edge

that will aid in achieving proper adhesion at the 3” (7.6 cm) vertical laps. If the sheet is run horizontally, the vertical laps must be a minimum of 6” (15.2 cm) and the selvage edge must be removed from the sheet or fully covered by the counterflashing. The finished flashing ply must extend out onto the field of the roof as shown on the applicable construction detail, and must be extended a minimum of 4” (10.2 cm) beyond the edge of the prior flashing plies. The flashing must be soundly adhered to the parapet, cant area and roof surface to result in a minimum void, non-bridging construction.

F. Base flashing heights must be a minimum of 8” (20.3 cm) and a maximum of 24”

(61.0 cm) above the roofline. G. Corner membrane flashings, such as “bow ties” for outside corners and

“footballs” for inside corners or other membrane reinforcements are required to ensure that base flashing corners are sealed at cant areas. An alternate method of corner reinforcing is to install a smooth MB membrane reinforcement piece on the prepared corner substrate prior to final surfacing membrane. Refer to MB Flashing Details section of the Manufacturer’s Application and Specifications Manual.

TS-21

3.11 Roof Penetrations

A. Liquid Flashing Membrane B. Substrate Preparation

1. Prepare the surface using a grinder or other suitable methods. Remove rust, residual asphalt or any other surface contaminants.

2. Flashing material requires a clean, dry surface to assure adequate adhesion.

Where necessary clean the surface with isopropyl alcohol and allow it to flash off prior to the application of liquid flashing. Note: Do not use cleaning product such as mineral spirits or xylene, or any hydrocarbon solvent, as it will leave a film and impede adhesion of the liquid flashing.

C. Installation

1. To assure a neat installation, tape off the area to be flashed. 2. Measure any gaps. Fill any gaps ¼ inch (6 mm) to ½ inch (13 mm) with M-

Bond sealant prior to installation of liquid flashing base coat. Gaps under ¼ inch (6 mm) do not require the application of sealant. Gaps ½ inch (13 mm) and larger require a backer rod to keep the sealant in place. (Fig 2)

3. Remove cap from liquid flshing pouch and apply the application tip (enclosed). Install a base coat of liquid flashing in the taped off area to a 30 wet mil (0.762 mm) thickness using the enclosed notched trowel or a china bristle brush.

4. Embed precut pieces of flashing fabric into the base coat of liquid membrane, so that they extend a minimum of 4 inches (102 mm) on to the field membrane and 4 inches (102 mm) up the penetration. Use a china bristle brush or notched trowel to work the fabric into the base coat of liquid flashing so that it lies smooth and flat.

5. Install the second coat of liquid flashing to a thickness of 30 wet mils (0.762 mm), working the liquid flashing completely over the fabric and extending a minimum of 2 inches (51 mm) past the end of the fabric.

6. Complete the flashing by broadcasting granules immediately into the completed flashing. Once cured [approximately 24 hours at 70° F (21.1°C) and 50% humidity] the membrane may be coated with the finish coating.

7. If the opened pouch contains unused liquid flashing, it may be reused for up to 14 days if properly sealed. To properly seal the pouch, squeeze all excess air from the pouch and return the cap. Do not use if material does not flow freely from pouch or has cured particles.

8. Wet material may be cleaned up with isopropyl alcohol. Cured material may be abraded from the substrate.

TS-22

3.12 Sheet Metal

A. All metal edge details scheduled to be included in the Edge to Edge Coverage guarantee must be submitted and approved in writing by the manufacturer prior to project commencement

B. Metal should not be used as a component of base flashing. Because of the

high coefficient of expansion of sheet metals and the large temperature changes that can be experienced on a roof, sheet metal or exposed metal components must be isolated from the waterproofing components of the roofing and flashing system as efficiently as possible to prevent the metal from splitting the membranes.

C. All metal edge details scheduled to be included in the edge to edge warranty

coverage must be submitted and approved in writing by the manufacturer prior to project commencement.

D. When it is unavoidable to use metal in the roofing system (i.e., lead flange at

I. Metal termination bars shall be a minimum of 1/10” (3 mm) thick x 1” (25

mm) wide with preformed sealant edge lap. Bar should have 1/4” (6 mm) x 3/8” (10 mm) slotted holes on 4” (10.2 cm) centers to facilitate mechanical anchorage.

TS-23

Note: Termination bars are not suitable in all base flashing and wall

flashing conditions. Termination bars may only be used in conjunction with an appropriate counter-flashing extending a minimum of 4” (10.2 cm) below the termination bar.

J. Metal flanges for gravel stops, eave strips, and pitch pockets to be used in

conjunction with roofing shall be primed (both sides), set in modified trowel grade cold adhesive applied material for SBS roof systems. Flanges shall be a minimum of 3 1/2” (8.9 cm) wide for gravel stops or eave strips and 4” (10.2 cm) wide for projections and extensions through the roof. The gravel stop lip should be at least 3/4” (19 mm) high. Eave strip lips shall be at least 3/8” (10 mm) high. Provisions must be made for securing the skirt to the face of the wall. This may be a wood nailer strip for masonry and metal construction. In all cases, gravel stop and eave strip nailer should be fastened to the deck or deck system with adequate resistance against wind forces.

K. Conduits and piping such as electrical and gas lines must be set on wood

blocking or some other form of support. Wood blocking/supports must be set on pads constructed of an additional layer of roof membrane material.

3.13 Metal Roof Edge/Fascia - After the roof insulation board, the base sheet and the

interply are in place, fasten the continuous galvanized anchor cleat, 12" o.c, 6" o.c. at corners. Fasten the roof edge flange to wood nailer, fasteners staggered 6" o.c. and snap into continuous cleat. Install cap sheet on top of roof edge flange.

3.14 Walkways

A. Walkways for normal rooftop traffic may be constructed from two plies of modified bituminous membrane of the same type as the field of the roof. This type of walkway is not for sidewalk or patio-type use.

B. Construct walkways by solidly adhering a first ply of smooth surfaced

membrane to the field of the roof followed by a granule surfaced membrane to the surface of the first ply.

TS-27

3.23 Bonding Agent -

A. Surface Preparation -

1. All areas of repair MUST be not less than 1/8 inch in depth. Preparation work should be done by high pressure water blast, scabbler, or other appropriate mechanical means to obtain an exposed aggregate surface with a minimum surface profile of ∀1/16 inch (CSP)

2. Saturate surface with clean water. Substrate should be saturated surface dry (SSD) with no standing water during application

B. Mixing - Shake contents of both Component >A= and Component >B=. Empty entire contents of both Component >A= and Component >B= into a clean, dry mixing pail. Mix thoroughly for 30 seconds with a paddle on a low speed (400-600 rpm) drill. Slowly add the entire contents of Component >C= while continuing to mix for 3 minutes until blend is uniform and free of lumps. Mix only that quantity that can be applied within its pot life.

C. Application as a Bonding Agent - Apply by stiff-bristle brush or broom. Spray apply with Goldblatt Pattern Pistol or equal equipment. For best results, work the bonding slurry well into the substrate to ensure complete coverage of all surface irregularities. Apply the freshly mixed roof screed wet on wet, or up to the maximum recommended open time, onto the bonding slurry. Maximum recommended open time between application of Armatec 110 and roof screed/pitching mortar or concrete:

80°-95°F (26°-35°C) 6 hours 65°-79°F (18°-26°C) 12 hours 50°-64°F (10°-17°C) 16 hours 40°-49°F (4°-9°C) wet-on-wet

D. Limitations -

must be applied "wet on wet". 4) Substrate profile as specified is still required. 5) As with all cement based materials, avoid contact with

aluminum to prevent adverse chemical reaction and possible product failure. Insulate potential areas of contact by coating aluminum bars, rails, posts etc. with an appropriate epoxy such as Sikadur Hi-Mod 32.

FOR CONCRETE ROOF SCREED/PITCHING – 3.24 Concrete Roof Screed/Pitching -

Important Notes - Prior to application of flash patch mortar

1. All areas of work must have been pressure-washed 2. Bonding agent must has been applied as per directions given above

TS-28

A. Mixing Mortar - Pour approximately 7/8 of Component >A= into the

mixing container. Add Component >B= (powder) while mixing continuously. Mix mechanically with a low-speed drill (400- 600 rpm) and mixing paddle or mortar mixer. Add remaining Component >A= (liquid) to mix if a more loose consistency is desired. Mix to a uniform consistency, maximum 3 minutes. Thorough mixing and proper proportioning of the two components is necessary.

B. Mixing Concrete for Areas Up to 2" thick - Pour all of Component

>A= into mixing container. Add all of Component >B= while mixing, then introduce 3/8 inch coarse aggregate. Mix to uniform consistency, maximum 3 minutes. Addition rate is 20 lbs. per bag. The aggregate must be non-reactive (reference ASTMC1260, C227 and C289), clean, well graded, saturated surface dry, have low absorption and high density, and comply with ASTM C 33 size number 8. Do not use limestone aggregate.

C. Application & Finish – Flash patch mortar must be scrubbed into the

substrate, filling all pores and voids. Force material against edge of repair, working toward center. After filling repair, consolidate, then screed. Allow mortar or concrete to set to desired stiffness, then finish with sponge float for a smooth surface.

D. Curing - As per ACI recommendations for portland cement concrete,

curing is required. Moist cure with wet burlap and polyethylene, a fine mist of water or a water-based compatible curing compound. Curing compounds adversely affect the adhesion of following layers of mortar, leveling mortar or protective coatings. Moist curing should commence immediately after finishing. Protect newly applied material from direct sunlight, wind, rain and frost.

E. Limitations -

1) Application thickness – Min. Max. in one lift Neat: 1/8 A 1" Extended: 1" 4" 2) Minimum ambient and surface temperatures 45°F (7°C) and

rising at time of application. 3) Do not use solvent-based curing compound. 4) As with all cement based materials, avoid contact with

aluminum to prevent adverse chemical reaction and possible product failure. Insulate potential areas of contact by coating aluminum bars, rails, posts etc. with an appropriate epoxy such as Sikadur Hi-Mod 32.

3.5 Securement of Wood Nailers (As per FM Data Sheet 1-49)

A. General Criteria

1. Minimum thickness of the nailer must be thick enough that the top of the nailer is flush with the top of the membrane underlayment.

2. The width of the nailers must exceed the width of the metal flange of edgings, scuppers, etc.

3. Lumber must be treated with salt preservatives only. Treatment with wood preservatives such as, Creosote, Pentachlorophenol, Copper Naphthenate and Copper 8-quinolinolate will adversely affect the membrane when in direct contact and are, therefore, are unacceptable.

4. Secure attachment of durable stock must be accomplished.

§ Wood nailers that are anchored to steel, wood or masonry decking should not be less than 2" X 6" nominal (minimum1-1/2" X 5-1/2").

§ Wood nailers should be Douglas Fir, Southern Yellow Pine or of wood having similar decay resistant properties.

B. Attachment to Masonry Walls

1. When fastening to a masonry wall, a 1/2 inch diameter anchor bolt is placed 48 inches on center at an 8 inch minimum depth (12 inches minimum when masonry walls are composed of lightweight aggregate or cinder). Each anchor bolt is positioned (staggered if the wood nailer is wider than 6 inches) in a block core or air space and tightly filled with concrete to the depth of the bolt.

TS-53

Note: Plastic parts must not be used with masonry anchors.

FMG has specific requirements concerning filling of cores or voids in the top course of cinder blocks.

For example: Projects requiring 75-psf or 90-psf ratings - fill the entire top course. Projects requiring 60-psf ratings - fill only required where anchor bolts are positioned (48 inches on center in the field, 24 inches on center at roof corners).

2. At outside corners, the fastening density must be increased within the first 8 feet in each direction by positioning anchor bolts 24 inches on center.

3. An alternate method may be used by installing 3/8 inch diameter anchor bolts spaced 32 inches apart. For outside corners, bolts are fastened 16 inches apart, 8 feet from each side of the corner.

C. Attachment of Additional Wood Nailers

1. When additional wood nailers are required, they must be attached with galvanized nails or lag screws that penetrate into the bottom nailer at 1-1/4 inches using a staggered fastening pattern in two rows at 24 inches apart.

2. The increased fastening density within 8 feet from outside corners is still required.

3. Contractors is responsible for confirming that all new wood nailers are attached in compliance with the above criteria.

(f) An asbestos abatement project may also be considered complete if the volume of air drawn for each of the five samples collected within the work area is equal to or greater than 1,199 L. of air for a 25 mm. filter or equal to or greater than 2,799 L. of air for a 37 mm. filter, and the average concentration of asbestos as analyzed by the TEM method in Appendix A, of 40 CFR part 763 subpart E. For the five air samples does not exceed the filter background level, as defined in Appendix A, of 70 structures per square millimeter (70 s/mm (2)). If the average concentration of asbestos of the five air samples within the work area exceeds 70 s/mm (2), or if the volume of air in each of the samples is less than 1,199 L. of air for a 25 mm. filter or less than 2,799 L. of air for a 37 mm. filter, the project shall be considered complete only when the requirements of subsections 19a-332a-12 (e) and 19a-332a-12 (g) are met.

(g) Air samples for post abatement reoccupancy may be collected and analyzed by phase contrast microscopy (PCM) to confirm completion of an asbestos abatement project involving less than or equal to 1500 square feet or 500 linear feet of asbestos-containing material. The project shall be considered complete when the results of samples collected in the work area and analyzed by phase contrast microscopy using the most current National Institute for Occupational Safety and Health (NIOSH) method 7400, to show that the concentration of fibers for each of the five samples is less than or equal to a limit of quantitation for PCM (0.010 fibers per cubic centimeter (0.010 f/cm (3)) of air). (Effective December 27, 1990.)

19a-332a-14. Inspection of asbestos abatement projects (a) The Commissioner or authorized agent shall, after proper identification, have the right to

enter into any facility, or onto any property where asbestos abatement is planned or is being performed or has been performed in order to determine whether such asbestos abatement is being performed in a manner consistent with good safe practices and in accordance with these regulations.

(b) Entry into the facility or onto the property where asbestos abatement is being planned or performed shall be at reasonable times. (Effective August 5, 1988.)

19a-332a-15. Order to cease activity (a) Whenever the Commissioner has reason to believe on the basis of inspections or tests

that asbestos abatement is being performed in violation of these regulations or, in the judgment of the Commissioner, is endangering the public's health, the Commissioner may issue a written or printed cease activity order to any person who performs, supervises or controls such asbestos abatement. Such order shall specifically describe the nature of the violation or condition endangering the public's health.

(b) After receipt of a cease activity order, no person shall conduct asbestos abatement except in accordance with the provisions of the order.

(c) Compliance with the provisions of a cease activity order shall be determined by the Commissioner on the basis of re-inspection or additional tests as deemed necessary by the Commissioner.

(d) Within seven (7) business days of receipt of a written request of the person subject to a cease activity order, the Commissioner shall hold a hearing to provide the person subject to the order an opportunity to be heard and show that asbestos abatement is being performed in accordance with these regulations and/or without endangering the public health. The cease activity order shall remain in effect until seven days after said hearing, within which time the Commissioner shall determine whether said order should continue in effect. The cease activity order shall be revoked at the end of said seven day period if no decision is made by the Commissioner or if so ordered by the Commissioner. (Effective August 5, 1988; Amended December 27, 1990.)

19a-332a-16. Application by the attorney general to the court Whenever, in the judgment of the Commissioner, any person has engaged in or is about to engage in any acts or practices which constitute or will constitute a violation of these regulations, the Commissioner may request the Attorney General to make application to a court of appropriate jurisdiction for an order enjoining such acts or practices or for an order directing compliance with these regulations.
