WITNESSETH, That the Contractor and the Owner will execute this contract in five

(5) counterparts, each of which shall be deemed an original, for the considerations

hereinafter named, agree as follows:

ARTICLE I - THE WORK

It is agreed that the Contractor shall furnish all labor, materials, and equipment, and perform all of the work shown and called for on the Drawings and described in the Specifications entitled – City Project WWTP-14-001, WWTP – East Ash Lagoon Reconstruction Project, ITB-W-8904 prepared by the Waste Water Treatment Plant Facilities Engineer or designee, acting as, the Engineer, and shall comply with all provisions of the Contract Documents. The Contract Documents being defined to include the Contract, Bonds, Drawings, Advertisement, Instructions to Bidder, Proposal, Specifications, General Conditions, Supplemental Specifications and any supplements or amendments agreed to by both parties. ARTICLE II - THE TIME It is agreed that the Contractor shall, upon execution of this Contract, begin construction within 10 working days from the date of the written Notice to Proceed, and shall prosecute the work in such manner as to fully complete all work, including cleanup and restoration by July 3, 2014 for the East Ash Lagoon Reconstruction Project. The time of beginning, rate of progress and hours of completion are considered essential elements of the Contract. Section 241 and 242 of the General Conditions portion of this contract shall apply to issues of progress of work and time for completion.


C-2

It is agreed that if the Contractor shall be unavoidably delayed in beginning or fulfilling this Contract by reason of excessive storms or floods, or by Acts of Providence, or by general strikes, or by court injunction, or by stopping of the work by the Owner because of any emergency or public necessity, or by reason of alterations ordered by the Owner, the Contractor shall have no valid claim for damages on account of any cause or delay; but he shall in such case be entitled to such an extension of the above time limit herein, as the Engineer shall adjudge to be just and reasonable; provided, however that formal claim for such extension shall be made in writing by the Contractor within a week after the date upon which such alleged cause or delay shall have occurred. ARTICLE III - DIFFERING SITE CONDITIONS CLAUSE It is agreed that in all improvement contracts that exceed $75,000.00 if a surface or subsurface condition differs materially from those stated in this contract, the Contractor shall promptly notify the Owner in writing before disturbing the physical condition of the property. If after prompt inspection by the Owner, any materially different condition increasing or decreasing the cost or time needed to perform the contract is determined to exist, a written adjustment shall be made to modify the contract. The Contractor shall not be entitled to an adjustment if no notice of the materially differing condition is given in writing to the Owner, or if the Contractor has already received final payment under this contract. It is further agreed that if the Contractor does not agree with the Owner’s determination regarding the differing condition, at the Owner’s option, the Owner and the Contractor shall arbitrate the Contractor’s entitlement in accordance with the rules of the American Arbitration Association. ARTICLE IV - LIQUIDATED DAMAGES It is expressly covenanted and agreed that response time is and shall be considered of the essence of the Contract. In the event that the Contractor shall fail to perform the entire work agreed to by or at the times herein mentioned or referred to in Article II, or within some other certain date subsequent to this to which the time limit for the completion of the work may have been advanced under the provisions of Article II, the Contractor shall pay unto the Owner as and for liquidated damages and not as a penalty, the sum of $500.00 for each and every calendar day after the allotted number of calendar days that the work remains incomplete or inactive that the Contractor shall be in default. Said sum of $500.00 per day, in view of the difficulty of estimating such damages with exactness, is hereby expressly fixed and agreed upon as the damages which will be suffered by the Owner for reason of such defaults. It is also understood and agreed that the liquidated damages herein before mentioned are in lieu of the actual damages arising from such breaches of this Contract, which said sums the Owner shall have the right to deduct from any monies in his hands otherwise due or to become due to the Contractor or to sue for and recover compensation for damages for non-performance of this contract at the time stipulated herein and provided.


C-3

ARTICLE V – OWNER’S RIGHT TO COMPLETE It is agreed that if at any time the Contractor should abandon his work; or if he should be adjudged as bankrupt, or if his performance of this Contract is being unnecessarily or unreasonably delayed; or if he should make a general assignment for the benefit of his creditors; or if a receiver should be appointed on account of his insolvency; or if he should persistently or repeatedly fail to supply enough properly skilled workmen or sufficient materials for the work; or if he should habitually fail to make prompt payment to subcontractors or to pay promptly for materials and labor; or if he should persistently disregard laws or ordinances or the directions of the Engineer; or if he should willfully and repeatedly violate any of the substantial provisions of this Contract, then in such case the Owner, after giving the Contractor and his sureties written notice thereof, may order him to discontinue all work under this Contract, or any part thereof. Thereupon, the Contractor shall at once discontinue such work or such part thereof, and shall cease to have any right to the possession of the ground. The Owner shall have the right to finish the work, or part thereof, by contract or otherwise as he may elect, and for that purpose to take possession and make use of such materials, tools, building appliances and equipment as may be found upon the work, and to charge the cost and expense of such completion to the Contractor. The Contractor shall not be entitled to receive any further payment until the work is finished. If the unpaid balance of the Contract price shall exceed the expense of finishing the work, including compensation for additional managerial and administrative services, the amount of such excess shall be paid to the Contractor. It is expressly stipulated and agreed that from and after the date of the order to discontinue work, and until such work shall have been finally completed by the Owner, neither the Contractor nor any of his agents or employees shall remove or make any effort directly or indirectly to remove any of the above mentioned materials, tools, building appliances or equipment from the points at which they were located on the date of said order, except upon the written consent of the Owner to do so. It is further understood and agreed that the foregoing provisions of this article are without prejudice to any other right or remedy which the Owner may have under this Contract. ARTICLE VI - ASSIGNMENT OF CONTRACT It is agreed that the Contractor shall not assign or transfer this Contract or sublet any part of the work embraced in it, except with the written consent of the Owner to do so. It is further agreed that all parts of the work which may be performed by a subcontractor shall be done in conformity with and be subject to all the provisions of the Contract Documents exactly as if performed by the Contractor and his immediate employees and workmen. No subletting of the work shall in any way diminish or weaken the responsibility of the Contractor for all parts of the work or lessen his obligations and liabilities under this Contract.


C-4

It is likewise agreed that the Contractor shall not assign, either legally or equitably, any of the monies payable to him under this Contract, or his claim thereto, except with the written consent of the Owner. ARTICLE VII - THE CONTRACT SUM It is agreed that, in consideration of the faithful and entire performance by the Contractor of his obligations under this Contract, the Owner shall pay to him the sum not to exceed , determined by the measured quantities and the respective unit prices herein named at the time and in the manner hereinafter stipulated. Such an amount shall be modified by such sums for alterations as may have been determined under the provisions of the General Conditions herein, and diminished by such sums as the Owner may lawfully deduct and retain as liquidated damages under the provisions of Article III of this Contract. The Contractor shall submit written requests for monthly progress payments to the City’s designee by the 24th day of each month in accordance with Article VIII of the Contract. At about the close of each month the Engineer will make an estimate of the amount and value of the work which has been satisfactorily done under this Contract during that month, or since the date of the last preceding estimate. Such estimate shall not be required to be made by strict measurement or with exactness, but may be made either wholly or in part by appraisement or estimation or by a consideration of accounts for labor and materials, and it shall be sufficient if it is approximate only. Any error or inaccuracy which may occur in any such progress estimate may be allowed for or corrected in any subsequent estimate. It is agreed that before the Contractor shall demand partial or final estimates or payments he shall furnish to the Owner, if and when requested to do so, supported, if requested, by sworn statements, satisfactory evidence that all persons who have supplied labor, materials, or equipment for the work embraced under this contract have been fully paid for the same; and that in case such evidence be not furnished as aforesaid, such sums as the Owner may deem necessary to meet the lawful claims of such persons may be retained by the Owner from any monies that may be due or become due to the Contractor under this Contract until such liabilities shall be fully discharged and the evidence thereof be furnished to the Owner. Each month progress payment requested, including reasonable interest if requested in compliance with Public Act No. 524 of the Public Acts of 180, shall be paid within 1 of the following time periods whichever is later:


C-5

ARTICLE VII - THE CONTRACT SUM (Cont’d) a. Thirty days after the Engineer has certified to the owner that work is in place in

the portion of the facility covered by the applicable request for payment in accordance with the Contract Documents

b. Fifteen days after the Owner has received the funds with which to make the

progress payment from a department or agency of the Federal or State government, if any funds are to come from either of those sources.

Upon failure of the Owner to make a monthly progress payment, within the preceding time limits, the person designated by the Contractor to submit requests for progress payments may include reasonable interest on amounts past due in the next request for payment. No progress estimate made or certified by the Engineer and no partial payment made to the Contractor by the Owner shall be deemed or construed as an acceptance of any part of the work under this Contract. As soon as practicable after the satisfactory completion of all work covered by this Contract, the Engineer will make a final inspection of the work as a whole, and will make up a final estimate of the total amount due the Contractor under the terms of the Contract. Upon the acceptance of the completed work, the Owner will pay to the Contractor the entire amount of such final estimate, less the sums previously paid and less such sums as the Owner may deem to be necessary to meet the undischarged obligations of the Contractor, for labor, materials or equipment furnished for the work. The Contractor shall file with the Owner a sworn statement that all claims for amounts due for labor, materials and equipment furnished for this work have been paid in full, or he shall so file in lieu thereof, a sworn statement showing in detail the nature and amount of all unpaid claims for said labor, materials and equipment. ARTICLE VIII - ANTICIPATED CONDITIONS AND WORK BY OTHERS The Contractor further acknowledges that he is not entitled to any additional compensation by reason of conditions being different from those anticipated or by reason of his failing to fully acquaint himself with the site, the conditions, and the work now in place or on account of interference by the Owner or by any other Contractor’s activities which affect the work of this Contract. ARTICLE IX - MISCELLANEOUS The Contractor acknowledges that he has not received or relied upon any representations or warranties of any nature whatsoever from the City of Warren, its agents or employees, and that this Contract is entered into solely upon the Contractor’s own independent business judgment.

In the event of a conflict between a term in the General Conditions and other contract documents, the General Conditions terms shall be subordinate to the conflicting term. The contractor shall be responsible to comply with the provisions of all Contract Documents. 203. – PLANS AND INTENT General and detailed plans showing the nature and scope of the work are on file at the office of the City Engineer and are hereby made a part of this Contract, it being mutually understood and agreed that when taken together the plans and contract documents are complementary, and what is called for by any one shall be binding as if called for by all. The intent of the Contract Documents is to include in the contract price the cost of all labor and materials, water, fuel, tools, plant, equipment, light, transportation, and all other expenses as may be necessary for the proper execution and completion of the work. All items of work noted on the plans or in the specifications that are not specifically noted in the proposal as pay items, shall be considered as incidental to the construction of the project, and shall be constructed at no extra charge to the City. These contract drawings may be supplemented by other drawings furnished by the Contractor and approved by the Engineer during the progress of the work as he may deem to be necessary or expedient. All such supplementary contract drawings or instructions are intended to be consistent with the Contract Documents. Therefore, no extra charge will be allowed on a claim that particular supplemental contract drawings or instructions differed from the Contract Documents, incurring extra work, unless the Contractor has first brought the matter, in writing, to the Engineer’s attention for proper adjustment before starting on the work covered by such and has received from the Engineer an order in writing to so proceed. In addition to the set of drawings and specifications procured for bidding purposes, the Contractor shall be furnished with an additional five (5) sets of drawings and specifications upon receipt of the award of bid. Any additional sets of drawings or specifications required by the Contractor will be furnished at the cost of $20.00 per set.

The surety on each bond shall be a duly authorized surety company satisfactory to the City. 205. - MAINTENANCE AND GUARANTEE BOND The Contractor, upon Contractor’s execution of the Contract, as a condition precedent to final payment, shall execute a guarantee to the City warranting for a period of three (3) years from the date of final payment to keep in order and repair any defect in all the work done under this Contract, either by the Contractor or its subcontractors, or the material suppliers, that may develop during said period due to improper materials, defective equipment, workmanship, or arrangements, and any other work affected during the repair of such imperfections shall also be made good, all without expense to the City, and the Contractor shall execute to the City, the enclosed Maintenance and Guarantee Bond. When the specifications call for a guarantee period greater than three (3) years, the Contractor shall provide such longer guarantee period. 206. - ADDITIONAL OR SUBSTITUTE BOND If at any time the City, for a justifiable cause, shall become dissatisfied with any surety on a Performance or Payment Bond, the Contractor shall, within five (5) days after notice from the City so to do, substitute an acceptable bond on the required form and in the required amount signed by another surety that is approved by the City. The premiums on such bond shall be paid by the Contractor. No additional construction will be allowed and no further payments shall be deemed due or made until the new surety shall have furnished an acceptable bond to the City. 207. - NO WAIVER OF CONTRACT The acceptance of any work or any part of the work by the City, the issuance of an order, the execution of a certificate by the City for payment of money, the payment for any work or part of the work, granting an extension of time, providing a measurement or any possession taken by the City shall not operate as a waiver of any portion of the contract or any power herein reserved to the City, or any right to damage herein provided. Further, the waiver of any breach of contract shall not be held to be a waiver of any other breach or a subsequent breach of contract. 208. - ORAL AGREEMENT An oral order, objection, claim or notice by any party to the others shall not affect or modify any of the terms or obligations contained in any of the contract documents, and none of the provisions of the contract documents shall be held to be waived or modified by reason of any act whatsoever, other than by a definitely agreed waiver or modification thereof in writing.


209. - PROHIBITED INTERESTS No official of the City who is authorized in such capacity on behalf of the City to negotiate, make, accept or approve, or to take part in negotiating, making, accepting, or approving any architectural, engineering, inspection, construction or materials supply contract or any subcontract in connection with the construction of the project, shall become directly or indirectly interested personally in the Contract or in any part hereof.

Should the City be prevented or enjoined from proceeding with the work, or from authorizing its prosecution, or by reason of its inability to procure any lands or rights-of-way and/or easement for the said work, the Contractor shall not be entitled to make or assert any claim for damage by reason of said delay, or to withdraw from the Contract except by consent of the City; but time for completion of the work shall be extended in writing, to such time as the City determines will make up for the time lost by such delay. 211. - WORKING HOURS All construction shall not begin before sunup or at the earliest 7:30 a.m. and all construction shall cease at sundown or at the latest 7:30 p.m. The Contractor shall adhere to this schedule unless specifically authorized in writing by the City Engineer.

If any part of the Contractor’s work depends, for proper execution or results, upon the work of any other Contractor, the Contractor shall stay informed of the progress and inspect the work of the other Contractor to promptly report to the Engineer any lack of progress or defects in such work that render the Contractor’s work unsuitable for proper performance and results.

He shall notify the Engineer immediately thereafter. Any claim for compensation by the Contractor due to such extra work shall be promptly submitted to the Engineer in writing for approval. Where the Contractor has not taken action but has notified the Engineer of an emergency threatening injury to persons or damage to the work or any adjoining property, he shall act as instructed or authorized by the Engineer.

One copy of such notice of claim shall be forwarded by the City to the surety on the Contractor’s Labor and Material Bond. However, any action of the City shall in no way act to relieve the surety on the Contractor’s Labor and Material Bond from any of its liability, nor shall it relieve any person, firm, or corporation from any responsibility to protect its interest in the manner prescribed by the above acts. 222. - LIENS Neither the final payment or any part of the retainage or interest earned on retainage shall become due until the Contractor shall deliver to the City a complete release of any and all claims or liens arising out of this contract, or in lieu of a release, receipts in full. In addition, the Contractor shall deliver to the City an affidavit that the releases and/or receipts include all the labor and material for which a claim or lien could be filed.


223. - PAYMENTS WITHELD In addition to the provisions of the paragraph entitled “250 - Estimates and Payments to Contractors”, of these General Conditions, the City may withhold, or on account of subsequently discovered evidence, nullify the whole or a part of any certificate for progress payment to such extent as may be necessary to protect itself from loss on account of:

The mention of any specific duty or liability of the Contractor in any part of the specifications shall not be construed as a limitation or restriction upon any general liability or duty imposed upon the Contractor by the specifications. 228. - CONTRACTOR’S SUPERVISION AND ORGANIZATION The work under this Contract shall be carried out under the personal supervision of the Contractor or its properly authorized representative, who shall be on the project at all times during the construction and who shall have full and responsible charge of work with power to receive orders and carry out instructions. Failure to have a properly authorized representative on the project at all times will be sufficient reason to halt construction on the project and may be deemed a breach of the Contract. The Contractor’s superintendent and/or any of his assistants shall be promptly replaced in the event he or they prove to be incompetent and/or unsatisfactory to the Engineer. The Contractor shall at all times be responsible for the conduct and discipline of his employees and/or any subcontractor or persons employed by subcontractors. All workmen must have sufficient knowledge, skill and experience to properly perform the work assigned to them. Any foreman or workmen employed by the Contractor or subcontractor, who, in the opinion of the Engineer, does not perform his work in a skilled manner, or appears to be incompetent or to act in a disorderly or intemperate manner, shall, at the written request of the Engineer, by discharged immediately and shall not be employed again in any portion of the work without the approval of the Engineer.


229. - NOTICE All notices required shall be given in writing by either personal delivery to the Contractor, or the authorized personal representative, certified or registered mail at the respective addresses of the parties as set forth or as designated hereafter in writing. Notice by mail shall be deemed given on the date of mailing, postage prepaid. NOTICE FOR CITY: NOTICE FOR:

James Van Havermaat, P.E. NAME OF CONTRACTOR City Engineer Contact Person City of Warren Title One City Square Contractor Address Suite 300 Warren, MI 48093-2390 (586) 759-9300 Phone: Fax: (586) 759-9318 FAX: Authorized Representative 230. - INFORMATION SUPPLIED BY THE CONTRACTOR The Contractor shall submit to the Engineer full information as to the materials, equipment, and arrangements which the Contractor proposes to furnish. This information shall be complete to the extent that the Engineer may intelligently judge if the proposed materials, equipment, and arrangements will meet the Contract requirements. Prior to the approval of materials, equipment, and arrangements by the Engineer based on the information submitted by the Contractor, any work done by the Contractor shall be at his own risk. The Contractor shall submit to the City a schedule of quantities and costs, progress schedules, payrolls, reports, estimates, records and other data as the City may request concerning work performed or to be performed under this Contract. The approval of information covering materials, equipment, and arrangements by the Engineer shall in no way release the Contractor from his responsibility for the proper design, installation, and performance of any material, equipment, or arrangement, or from his liability to replace same should it prove defective. 231. - CONSTRUCTION SCHEDULE Immediately after receiving notice of award of contract, and before the commencement of work, the Contractor shall prepare and submit to the Engineer a construction progress schedule showing in a clear, graphical manner, satisfactory to the Engineer, the proposed dates for the commencement, progress and completion of each of the various phases or divisions of work on each street or location in the project. The schedule shall be predicated on the completion of the work on or before the date of completion as stated in the proposal. Upon approval of the progress schedule it shall become a part of the contract documents. If during the course of the work, the time of completion is extended by change order or it becomes apparent that the progress schedule is unrealistic, it shall be revised and approved.


232. - SHOP DRAWINGS After checking and verifying all field measurements, the Contractor shall submit to the Engineer for approval five copies (or at the Engineer’s option, one reproducible copy) of all shop drawings, which shall have been checked and approved by the Contractor. The Contractor shall be responsible for their submission at the proper time so as to prevent delays and delivery of materials. A minimum of ten (10) calendar days shall be allowed for checking and processing shop drawings. The data shown on the shop drawings shall be complete with respect to the dimensions, design criteria, materials of construction and the like to enable the Engineer to review the information as required. All details shall show clearly the relations of the various parts to the main members and lines of the structure, and where correct fabrication of the work depends upon field measurements, such measurements shall be made and noted on the drawings before being submitted for approval. All submissions shall be referenced properly to indicate clearly the location, service, and function of each particular item. At the time of each submission, the Contractor shall, in writing, on each drawing call the Engineer’s attention to any deviation that the shop drawings may have from the requirements of the Contract documents. The Engineer shall check all shop drawings with reasonable promptness, but his checking and approval shall be only for conformance with the design concept of the project and for compliance with the information given in the contract documents. The approval of shop drawings shall not be construed as a complete check but will indicate only that the general method of construction and detailing is satisfactory. Approval of drawings will not relieve the Contractor of the responsibility for any error which may exist. The Contractor shall be responsible for the dimensions and design of adequate connections and details, and satisfactory construction. The Contractor shall make any corrections required by the Engineer and return the required number of corrected copies of shop drawings. The approval of a separate item as such will not indicate approval of the assembly in which the item functions. No work requiring a shop drawing shall proceed until the submission has been approved by the Engineer. The Engineer’s approval of shop drawings shall not relieve the Contractor from his responsibility for any deviations from the requirements of the contract documents, unless the Contractor has in writing on the drawing called the Engineer’s attention to the deviation at the time of submission and the Engineer has given written approval to the specific deviation, nor shall it relieve the Contractor from errors or omissions in the shop drawings.


233. - GENERAL REQUIREMENTS OF MATERIALS AND WORKMANSHIP Whenever in any of the contract documents, an article, material or equipment is defined by describing a proprietary product, or by using the name of a manufacturer or vendor, the term “or approved equal” if not inserted, shall be implied. The specific article, material or equipment mentioned shall be understood as indicating the type, function, minimum standard of design, efficiency and quality desired and shall not be construed in such a manner as to exclude manufacturer’s products of comparable quality, design and efficiency. If materials or equipment of other makes or types than that specified by name are offered by the Contractor they will be given full consideration by the Engineer and the Engineer’s decision will be final as to whether the materials or equipment offered are equal to those specified. They shall not be purchased or installed without the Engineer’s written approval. Unless otherwise stipulated in the Specifications, all equipment materials, and articles incorporated in the work covered by this Contract are to be new and of the best grade of their respective kinds for the purpose. The contractor shall, if required, furnish such evidence as to kinds and quality of materials as the Engineer may require. The Contractor shall furnish suitable tools and building appliances and employ competent labor to perform the work to be done, and any labor or tools or appliances that shall not, in the judgment of the Engineer, be suitable or competent to produce this result may be ordered from the work by him, and such labor or tools or appliances shall be substituted therefore by the Contractor as will meet the approval of the Engineer. If not otherwise provided, material or work called for in the Contract shall be furnished and performed in accordance with well-known established practice and standards recognized by engineers and the trade. If any type of machinery, equipment, or tools are specifically needed to prosecute the work in an orderly, workmanlike manner, the Engineer may so direct the Contractor to procure same, before work is continued. 234. - CONTRACTOR’S TITLE TO MATERIALS No materials or supplies for the work shall be purchased by the Contractor or by any subcontractor subject to any chattel mortgage or under a conditional sale contract or other agreement by which an interest is retained by the seller. The Contractor warrants that he has good title to all materials and supplies used by him in the work, free from all liens, claims or encumbrances. 235. - TESTING AND SAMPLING Where called for in the specifications, samples of materials in the quantity named shall be submitted to the Engineer for approval. Where tests are required they shall be made at the expense of the Contractor, except as otherwise called for in the specifications, unless otherwise stipulated, the required tests may be made by the manufacturer and his certificate therefore submitted to the Engineer.


236. - ERRORS, CORRECTIONS & CHANGES IN DRAWINGS & SPECIFICATIONS The Contractor shall examine and check all drawings and specifications furnished by the City for dimensions, quantities, types of materials, and coordination with other parts of the work on this or related contracts. No structure, sewer pipe, water main, pavement or fixtures thereto shall be placed or constructed under conditions which may be expected to result in defective work. If the soil is not sufficiently stable to properly support structure, or if the Contractor wishes to question the materials prescribed, the Contractor shall stop work and immediately notify the Engineer. The Engineer shall review these conditions, and if he deems it necessary, the Engineer shall direct changes to be made in design or suggest changes in construction procedure before work is to continue. The Contractor shall not be allowed to take advantage of any error, omission or discrepancy, as full instructions will be furnished by the Engineer, and the Contractor shall carry out the instructions as if originally specified. In no case shall the Contractor proceed with the work in uncertainty, and any work done by the Contractor after the discovery of any error, omission, or discrepancy, until authorized, will be at the Contractor’s risk and responsibility. The work is to be made complete and to the satisfaction of the Engineer, notwithstanding any minor omissions in the specifications or plans. 237. - ESTIMATED QUANTITIES The quantities of the various classes of work to be done and materials to be furnished under this Contract, which have been estimated as stated elsewhere herein, are approximate and only for the purpose of comparing on a uniform basis the bids offered for the work under this Contract. The City or its agents are not to be held responsible should any of the estimated quantities be found incorrect during the construction of the work and the Contractor shall make no claim for anticipated profit, nor for loss of profit, because of a difference between the quantities of the various classes of work actually delivered, and the estimated quantities as herein stated. 238. - CHANGES IN WORK Under circumstances which, in the judgment of the Engineer, so necessitate, the Engineer shall have authority to require, by written order, changes in, additions to, or deductions from the work required by the Contract Documents; provided that if changes, additions or deductions are made, the general character of the work as a whole is not changed thereby. Adjustments in the Contract price, if any, because of any change, addition, or deduction in the work shall be determined as hereinafter provided, and any claim for extension of time for completion shall be adjusted at the time of ordering the change, addition, or deduction. No claims for changes, additions, deduction, adjustment of prices, or extensions of time for completion thereof, shall be made or allowed unless done pursuant to a written order from the City specifically authorizing the changes, additions, or deductions. Drawings without a written order shall not be considered such authority. Written notice of claims shall be made to the Engineer before the commencement of the work. Where the written order diminishes the quantity of work to be done, this shall not constitute a basis for a claim for damages or anticipated profits on the work that may be dispensed with. It is understood and agreed that in case any change in, addition to, or deduction from the work is required, the change shall in no way invalidate the Contract and shall not affect or discharge the bonds furnished by the Contractor.


The Contractor, without extra charge, shall make such slight alterations as may be necessary to make adjustable parts fit to fixed parts, leaving all complete and in proper shape when done. When, in the opinion of the Engineer, a change in the work is of such an urgent nature that the Contractor does not have time to prepare an itemized estimate of cost, the Contractor shall, upon receiving written notice, proceed with the work and the cost will be negotiated later by one of the methods provided in these General Conditions. 239. - BASIS FOR DETERMINING COST OF CHANGES IN THE WORK Adjustments, if any, in the Contract price by reason of change in the work shall be limited to the amount specified in the written order authorizing the change in the work. Adjustments shall be determined by one or more of the following methods, the City reserving the right to select the method or methods, at the time the written order is issued: a) An acceptable lump sum proposal: To facilitate checking and acceptance, the proposal

shall be itemized with quantities and prices given for the various items.

b) Unit Price: The unit price shall be the “Unit Price” in the Contract, or fixed by subsequent agreement between the Engineer and the Contractor.

c) On a cost-plus–limited-basis: Either a “Not-to-Exceed” or a “Specified Maximum Limit” of Cost applied as follows: Cost shall be the actual and necessary costs incurred by the Contractor by reasons of the change in the work for:

1) Labor costs shall be the amount shown on the Contractor’s payrolls with payroll taxes added when taxes can be shown to have been incurred. In no case shall the rates charged for labor exceed the rates paid by the Contractor for the same class of labor employed by him to perform work under the regular items of the Contract.

2) Material costs shall be the net price paid for material delivered to the site of the work. If any material previously required is omitted by the written order of the City after it has been delivered to or partially worked on by the Contractor and consequently will not retain its full value for other uses, the Contractor shall be allowed the actual cost of the omitted material less a fair market value of the material as determined by the City.

3) Equipment rental shall be the actual additional costs incurred for necessary equipment. Costs shall not be allowed in excess of usual rentals charged in the area for similar equipment of like size and condition; including the costs of necessary supplies and repairs for operating the equipment. All costs shall be computed using the monthly rental rate and for periods of less than 30 days the daily rate shall be computed as 1/30 of the monthly rate. No costs, however, shall be allowed for the use of equipment on the site in connection with other work unless its use incurs actual and additional costs to the Contractor. If equipment not on the site is required for the change in the work only, the cost of transporting such equipment to and from the site shall be allowed.

4) Insurance premiums shall be limited to those based on labor payroll and to types of insurance required by the Contract. The amount allowed shall be limited to the net costs incurred as determined from the labor payroll covering the work. The Contractor shall, upon request of the City, submit verification of the applicable insurance rates and premium computations.


Plus, as herein used, is defined as a percentage to be added to the items 1, 2, and 3 of “Cost” to cover superintendence, use of ordinary tools, bond, overhead expense and profit. The percentage shall not exceed 15% on work done entirely by the Contractor and shall not exceed an aggregate total of 20% on work done by a subcontractor. Specified Maximum Limit of Cost is the amount stated in the written order or the City authorizing the change in the work. The amount to be allowed the Contractor shall be the “Cost”, and “Plus” the percentage or the specified maximum, whichever is the lesser amount.

The Contractor shall keep complete, accurate, daily records of the net actual cost of changes in the work and shall present such information in such form and at such times as the City may direct. 240. - CLAIMS FOR EXTRA COST If the Contractor claims that any instructions, by drawings or otherwise, not covered by the provisions of paragraphs entitled, “238 - CHANGES IN WORK” and “239 - BASIS FOR DETERMINING COST OF CHANGES IN THE WORK”, in these general conditions, involve extra costs, he shall give the Engineer written notice thereof, within forth-eight (48) hours after receipt of such instructions and in any event, before proceeding to execute the work. Said notice shall state the amount of the extra cost involved and the reasons why, in the opinion of the Contractor, the instructions require performance beyond that required by the contract resulting in the extra cost. Within a reasonable time after receipt by him of the Contractor’s notice, the Engineer shall decide whether or not the instructions require performance beyond that required by the contract that would involve the extra cost. The decision of the Engineer shall be made in writing and shall be final. If the Engineer shall decide that the instructions do require performance not required by the contract, that would involve extra cost, the Engineer shall thereupon either:

a) Issue a written order as provided for in paragraph entitled, “Changes in the Work”, in these General Conditions, to cover such instructions and extra cost, or

b) Rescind or modify the instructions so as to eliminate the extra cost.

Failure to comply with the foregoing conditions shall be deemed a waiver by the Contractor of any claim whatsoever. 241. - PROGRESS OF THE WORK After execution of the contract and upon written notice by the Engineer, the Contractor shall immediately order materials and equipment and begin work on the project. The time allowed for completion of the work contemplated in this Contract shall be as stated in the proposal. The work shall be prosecuted regularly and uninterruptedly, unless the Engineer shall otherwise specifically direct, with such force and at such points as to insure its full completion within the time herein stated. The Contractor at all times shall have a minimum of one complete construction crew working on the project unless authorization is received from the City Engineer to deviate from this requirement


If, in the opinion of the Engineer, it is necessary or advisable that certain portions of the work be done immediately, the Contractor, upon written order, shall proceed with such work without delay. Should he fail to so proceed, the Engineer may cause such work to be done and the cost of the same will be deducted from any money due or to become due the Contractor under this Contract. 242. - TIME FOR COMPLETION AND LIQUIDATED DAMAGES It is hereby understood and mutually agreed between the Contractor and the City, that the date of beginning and the time for completion as specified in the Contract for the work to be done hereunder are ESSENTIAL CONDITIONS of this Contract; and that the work in this Contract shall be commenced on a date to be specified in the order to proceed. The prompt completion of the work to be performed under this contract is considered by the City to be essential to the welfare, health and safety of the City. In the event of the failure or neglect of the Contractor to construct to substantial completion within the time specified in the proposal, or as extended by the City, the Contractor and/or his surety shall pay to the City as compensation and liquidated damages and not as a penalty, the sums set up in the Instructions to Bidders. Substantial completion is considered to be the time at which the various sections of the project may be utilized for the purposes intended. The Contractor agrees that said work shall be prosecuted regularly, diligently, and uninterruptedly at such rate of progress as will insure full completion thereof within the time specified. If the Contractor shall neglect, fail or refuse to comply with this requirement, then the Contractor does hereby agree to pay to the City the amount specified in the Contract, not as a penalty but as liquidated damages for such breach of Contract as hereinafter set forth, for each and every calendar day that the Contractor shall be in default. It is expressly understood and agreed, by and between the Contractor and the City, that the time for the completion of the work described herein is a reasonable time for the completion of the same, taking into consideration the average climatic range and usual conditions prevailing in this locality. The amount of liquidated damages per day is fixed and agreed upon by and between the Contractor and the City because of the impracticability and extreme difficulty of fixing and ascertaining the actual damages the City would in such event sustain, and said amount is agreed to be the amount of damages which the City would sustain and said amount shall be retained from time to time by the City from current periodical estimates. It is further agreed that time is of the essence of each and every portion of this Contract and of the specifications wherein a definite and certain length of time is fixed for the performance of any act whatsoever; and where under the Contract an additional time is allowed for the completion of any work, the new time limit fixed by such extension shall be of the essence of this Contract. Provided, that the Contractor shall not be charged with liquidated damages or any excess cost when the delay in completion of the work is due to an unavoidable delay of the Contractor in the commencement, prosecution, or completion of this work resulting from:

a) Any act of omission by the City or his agents.

b) Injunctions or acts of omissions of public authorities in consequence of act or omissions of the City or its agents.


c) Reason of any cause of circumstance, weather conditions being specifically accepted, which the City or its agents may decide is absolutely and clearly beyond the control of the Contractor.

d) Strikes, riots, war, insurrection or acts of God.

e) Unusually severe weather.

f) Acts of another Contractor in the performance of a contract with the City.

g) Any delays of subcontractors or suppliers occasioned by any of the causes specified above.

Unavoidable delays for the above reasons may entitle the Contractor to an extension of time for completion of the work. The time of completion of such portion or portions of the work directly affected by such delay shall be extended by the City, in writing, for a period equal to the number of days lost by reason of the aforesaid causes. Any of the above extensions shall only be made if the Contractor presents his claim within seventy-two (72) hours after the occurrence of said delay. In the case of extra work or revision of the contract documents, it shall become the sole responsibility of the Contractor to present such relevant facts and data as will clearly show to the City that the alleged delays, as claimed, are unavoidable and substantial and could not have been reasonably anticipated or guarded against. If, in the opinion of the City, the delays claimed are not valid, or that it appears likely that the Contract will not be completed within the time as agreed, including such extensions as may be allowed, then the Contractor, upon written request from the City shall increase his forces and work such extra hours per day beyond eight (8) hours or on Saturdays as shall be necessary to complete the work within the specified time of completion. Permitting the Contractor to continue and finish the work, or any part of it, after the time affixed for its completion, or after the date to which the time for completion may have been extended shall in no way operate as a waiver on the part of the City or his agents of any of its rights under this Contract. 243. - INJUNCTIONS Should the City be prohibited or enjoined from proceeding with the work, or from authorizing its prosecution, either before or after its commencement, by reason of any litigation or otherwise, the Contractor shall not be entitled to any damages by reason of the delays thereby caused, except for the actual cost of protecting such work as he may have under way; or for the cost of removal and replacement of tools, plants, and materials as he may have delivered for the work, and such cost shall be approved by the City. The Contractor shall not be entitled to withdraw from this agreement until such delays aggregate one (1) year; but the time of completion shall be extended for such time as in the judgment of the City shall be equal to the aggregate delay.


244. - USE OF COMPLETED PORTIONS OF THE WORK The City may, at any time during progress of the work after written notice to the Contractor, take over and place in service any completed portions of the work which are ready for service, although the entire work of the Contract is not fully completed, and notwithstanding the time for completion of the entire work or such portions may not have expired. The use of any portion of the work by the City under the provisions of this section, shall not constitute final acceptance of the work and shall not be construed as final acceptance of the work and shall not be construed to be a final estimate for such work. The date of final estimate shall be the date of final estimate for the entire project covered under this Contract. If such prior use increases the cost of or delays the work, the Contractor shall be entitled to such extra compensation, or extension of time, or both, as the Engineer may determine. 245. - CITY’S RIGHT TO PERFORM WORK If the Contractor should neglect to prosecute the work properly or fail to perform any provision of this Contract, the City, seven (7) days after written notice to the Contractor or sooner if the public health or safety is endangered, may, without prejudice to any other remedy he may have, make good such deficiencies and deduct the cost thereof from monies due the Contractor. 246. - CITY’S RIGHT TO TERMINATE CONTRACT If the Contractor should be adjudged bankrupt; or if a receiver should be appointed on account of his insolvency; or if he should abandon the work; or if he should persistently or repeatedly refuse or fail to supply enough properly skilled workmen or proper materials; or if he should fail to make prompt payment to subcontractors or suppliers or for labor; or persistently disregard laws, ordinances, or the instructions of the Engineer; or if he should fail to prosecute the work at a reasonable rate of progress; or otherwise be guilty of a substantial violation of any provision of the Contract, then the City, without prejudice to any other right or remedy, may serve written notice upon the Contractor and the Surety of its intention to terminate the Contract. The notices shall contain the reasons for such intention to terminate the Contract and, unless within seven (7) days after the serving of such notice upon the Contractor, such violation or delay shall cease and satisfactory arrangement of correction be made, the Contract, shall, upon the expiration of said seven (7) days, cease and terminate. In the event of any such termination, the City shall immediately serve notice thereof upon the Surety and the Contractor, and the Surety shall have the right to take over and perform the Contract; provided, however, that if the Surety does not commence performance thereof within seven (7) days from the date of the mailing to such Surety the notice of termination, the City may take over the work and prosecute the same to completion by contract or by force account at the expense of the Contractor. In such event, the City will take possession of the premises and will utilize in completing the work, such materials, appliances, tools, and plant as may be on the site of the work and necessary therefore. In such cases the Contractor shall not be entitled to receive any further payment until the work is finished. If the unpaid balance of the Contract price shall exceed the expense of finishing the work including compensation for additional managerial and administrative services, such excess shall be paid to the Contractor. If such expense shall exceed such unpaid balance, the Contractor shall pay the difference to the City. The expense incurred by the City as herein provided, and the damage incurred through the Contractor’s default, shall be certified by the Engineer.


247. - CONTRACTOR’S RIGHT TO STOP WORK OR TERMINATE CONTRACT If the work should be stopped under an order of any court, or other public authority for a period of three months, through no act or fault of the Contractor or of anyone employed by him or if payment is arbitrarily delayed for 60 days or more without reason as noted in the paragraph entitled “223 - Payment Withheld” of the General Conditions, then the Contractor may, upon seven days written notice to the City, stop work or terminate this Contract, and shall recover from the City payment for all work executed, as determined from the prices contained in the approved detailed estimate as computed by the Engineer, but no claim for extra compensation or damages shall be made or allowed because of such termination of the Contract except for any loss sustained upon any materials through no fault of his own. 248. - DISCRIMINATION The Contractor and any of the subcontractors shall not discriminate against any employee or applicant for employment in the performance of the Contract with respect to his or her hire, tenure, terms, conditions or privileges of employment or any matter directly or indirectly related to employment because of his race, color, religion, national origin, sex, height, weight, martial status and handicap that is unrelated to the individual’s ability to perform the duties of a particular job or position. Breach of this covenant may be regarded as a material breach of this Contract. The Contractor and the subcontractors shall not discriminate against any employee or applicant for employment in the performance of this Contract with respect to hire, tenure, terms, conditions or privileges of employment or any matter directly or indirectly related to employment because of age, except where based on a bonafide occupational qualification. 249. - DETAILED BREAKDOWN OF CONTRACT AMOUNT Where a Contract is awarded on a lump sum bid, the Contractor shall submit to the City for approval, a detailed estimate showing units, quantities, unit prices and amount of money for the several items entering into the work. The total in the detailed estimate shall equal the total amount of the Contract price. After approval, the detailed estimate shall become a part of the Contract. No payment or payments will be made to the Contractor until such detailed estimate is submitted. 250. - ESTIMATES AND PAYMENTS TO CONTRACTOR The Contractor shall submit written requests for monthly progress payments to the Engineer by the 24th of each month. At the close of each month, the Engineer will prepare a monthly progress estimate which will include all work that is in place and that has reached a stage eligible for payment as described in the “Basis of Payment" Section of the detailed Specifications for the type of work involved. A retainage of 10% will be withheld on all work included on a monthly progress payment until the total dollar value of the work included in the progress estimate reaches 50% of the dollar value of the total Contract. After the dollar value of the work included in the progress estimates exceeds 50% of the dollar value of the total Contract, additional retainage will not be withheld unless the Engineer


determines that the Contractor is not making satisfactory progress for any of the following reasons:

A. Defective work not remedied; B. Claims filed or reasonable evidence indicating probable filing of claims; C. Failure of the Contractor to make payments properly to a Subcontractor; D. A reasonable doubt that the contract can be completed for the balance then unpaid; E. Damage to another Contractor, to private property or to public property; F. Failure to diligently pursue the work.

If the Engineer determines that any of the preceding conditions exist, the retainage withheld will remain at 10% of the dollar value of all work, included in the progress estimates, that exceeds 50% of the dollar value of the total Contract. Retained funds shall be deposited, by the City, in an interest bearing account in a regulated financial institution in the State of Michigan which shall account for both retainage and interest on each Contract separately. The City is not required to deposit retained funds in an interest bearing account if the retained funds are to be provided under a State or Federal grant and the retained funds have not been paid to the City. The retainage and interest earned on retainage, less any deductions or losses as determined by Public Act No. 524 of the Public Acts of 1980, Section 125.1563, of the Michigan Compiled Laws, shall be released to the Contractor together with the final progress payment. At any time after the dollar value of the work included in the progress estimates reaches 94% of the dollar value of the total Contract, and upon the request of the original Contractor, the City shall release the retainage plus interest to the original Contractor, provided that the original Contractor provides to the City an irrevocable letter of credit in the amount of the retainage plus interest, issued by a bank authorized to do business in the State of Michigan, containing terms mutually acceptable to the Contractor and the City. If a dispute arises between the Contractor and the City as to the rights of the parties to retained funds and interest earned on retained funds, both parties agree as a part of this Contract to submit the dispute to the decision of an Agent in accordance with the following procedure, conditions and limitations: 1. The Contractor and the City shall designate an Agent who has background, training

and experience in the construction of the facilities similar to that which is the subject of the Contract as follows:

a. In an agreement reached within ten (10) days after a dispute arises. b. If an agreement cannot be reached within ten (10) days after a dispute arises, the

City shall designate an Agent who has background, training and experience in the construction of facilities similar to that which is the subject of the Contract and who is not an employee of the City.

2. The City may request dispute resolution by the Agent regarding the following:

a. At any time during the term of the Contract, to determine whether there has been a delay for reasons that were within the control of the Contractor, and the period of time that delay has been caused, continued, or aggravated by actions of the Contractor.


b. At any time after 94% of work under the Contract is in place and approved, whether there has been an unacceptable delay by the Contractor in performance of the remaining 6% of work under the Contract. The agent shall consider the terms of the Contract and the procedures normally followed in the industry and shall determine whether the delay was for failure to follow reasonable and prudent practices in the industry for completion of the project.

3. The Agent may request and shall receive all pertinent information from the parties and

shall provide an opportunity for an informal meeting to receive comments, documents, and other relevant information in order to resolve the dispute. The Agent shall determine the time, place, and procedure for the informal meeting. A written decision and reasons for the decision shall be given to the parties within fourteen (14) days after the meeting.

4. If the dispute resolution, by the Agent, results in a decision.

a. That there has been a delay as described in subsection 2.a. above, all interest earned on retained funds during the period of delay shall become the property of the City.

b. That there has been unacceptable delay as described in subsection 2.b. above, the

City may contract with a subsequent contractor to complete the remaining 6% of work under the Contract, and interest earned on retained funds shall become the property of the City. A subsequent contractor under this subsection shall be paid by the City from the following sources until each source is depleted, in the order listed below:

aa. The dollar value of the original contract, less the dollar value of funds already

paid to the original contractor and the dollar value of work in place for which the original contractor has not received payment.

bb. The dollar value of the original contract, less the dollar value of funds already

paid to the original contractor and the dollar value of work in place for which the original contractor has not received payment.

cc. Interest earned on retainage from the original contractor, or funds made

available under a letter of credit provided by this section.

5. If the City contracts with a subsequent contractor as provided in subsection 4.b. above, the final progress payment shall be payable to the original contractor within the time period specified in Section 2 (3) of Public Act 524 of the Public Acts of 1980, Section 125.1562 of Michigan Compiled Laws. The amount of the final progress payment to the original contractor shall not include interest earned on retained funds. The City may deduct from the final progress payment all expenses of contracting with the subsequent contractor. This section shall not impair the right of the City to bring an action or to otherwise enforce a performance bond to complete work under this Contract

PART 3 EXECUTION

3.1 EROSION PROTECTION-CROSSING DRAINS/STREAMS

A. In order to limit the length of time that the exposed area is subject to the elements and the subsequent conditions causing erosion, the contractor shall adhere to the following requirements. 1. The banks of drains will not be left unprotected for more than one day where

possible, but never more than seven days. Construction will not be allowed to continue at the expense of not providing stream bank protection. All spoils including organic and inorganic soils, vegetation and debris shall be placed above the ordinary high water mark, leveled and stabilized with sod and/or seed, fertilized and mulched, in such a manner as not to erode into any waterbody or wetland.

2. All disturbed drain banks will be finished with a slope not steeper than 2:1 (2 horizontal to 1 vertical) and in accordance with grading plans. Fill shall consist of inert materials which will not cause siltation nor contain soluble chemicals or organic matter which is biodegradable. All fill shall be contained in such a manner as not to erode into any watercourse. All raw banks shall be stabilized with sod, seed, fertilizer and mulch or riprapped as necessary to prevent erosion.

3. All raw soil will be either sodded or seeded, fertilized and mulched. On slopes greater than 10 percent, sod will be pegged for stability.

4. Deflection dikes consisting of gravel or other suitable material, reinforced by one row of sandbags, will be used to divert runoff from steep slopes adjacent to water courses, where contributing runoff could be great enough to cause slope erosion and resulting sedimentation at the ditch. Diversion berms, filter berms, diversion ditches or terracing may be appropriate.

5. Excavation shall stop some distance from ditches to leave a protective plug of 10 to 20 feet of unexcavated material at each bank. These plugs shall be left in place.

B. Any unforeseen situations that may be encountered during the course of construction, that may cause accelerated erosion and deposition of sediment into waterways and/or lakes, will be controlled by methods that may include sediment traps, sediment basins, or holding ponds. Any slope failures or development of gullies after construction has been completed will be corrected immediately.

3.2 EROSION PROTECTION-OPEN CUT CONSTRUCTION

A. In order to limit the length of time that the exposed area is subject to the elements and subsequent conditions causing erosion, the Contractor shall adhere to the following requirements. 1. Burlap Silt Traps (or equivalent) shall be placed between the frame and cover of all

manholes, catch basins, and gate wells in the construction area. The burlap shall be periodically replaced if silt buildup causes the trap to function improperly.

2. Underground piping and conduit construction, including installation of pipe, backfilling, surface restoration and removal of excess excavation shall be accomplished in one continuous operation. Backfilling, removal of excess excavated material and final or temporary stabilization (according to seasonal limitation) shall follow pipe laying and conduit construction by no more than 100 feet.

SOIL EROSION CONTROL CITY OF WARREN 02220 / 4 WWTP – EAST ASH LAGOON RECONSTRUCTION PROJECT



3. Excess excavated materials shall be removed from the job site. Excess excavated material shall be disposed of in accordance with Section 500 Concrete Paving. A soil erosion plan must be prepared by the Contractor for each fill area and it shall be approved by a proper authorized agency and implemented before starting filling operations.

3.3 APPLICATION OF PERMANENT STABILIZATION

A. Permanent stabilization shall be applied to all areas disturbed by the Contractor during completion of the work required by the Contract.

B. The stabilization shall be accomplished within 7 days of completion of the final earth change provided that change is made within the stated season for such stabilization.

C. If the final earth change is accomplished at a time outside of the stated seeding or sodding season, temporary stabilization shall be applied within 7 days of completion of the final earth change and shall be replaced with permanent stabilization as soon after the following April 20 as the ground is workable.

3.4 APPLICATION OF TEMPORARY STABILIZATION

A. Temporary stabilization shall be applied to areas where initial work has caused disturbance and the final earth change will not be completed immediately and to areas where the final earth change is completed between October 1 and April 20.

B. Temporary stabilization shall be applied to areas where the final earth change has been completed, including final grading and top soil placement, between the dates of October 1 and April 20. The disturbed areas shall have mulch placed and anchored as described in the following paragraphs. After April 20, areas to be seeded shall be seeded through the mulch. Mulch shall be added and anchored as necessary to replace that lost prior to April 20. Where sod is to be placed, the mulch will be removed or worked into the soil. If worked into the soil, the fertilizer application rate shall be increased by 25%.

C. Areas disturbed by construction activities but on which the final earth change has not been made shall be graded to provide positive drainage and shall be stabilized to prevent erosion.

D. Areas which receive an initial earth change during the period October 15 to April 1 and will not receive further work for any length of time within that season shall have mulch placed and anchored. If work is not anticipated in such areas prior to the following July 1, the area shall be seeded with temporary seeding on or shortly after April 1.

E. Areas which receive an initial earth change between April 1 and October 15 and on which no further work is anticipated within 3 months shall receive temporary seeding and mulch.

F. Areas which receive an initial earth change and on which further work is to be done within 3 months shall be graded to provide positive drainage and shall have mulch placed and anchored.




3.5 SEEDING FOR TEMPORARY AND PERMANENT STABILIZATION

A. Site Preparation 1. The seedbed immediately before seeding shall be firm but not so compact as to

prohibit the seed from securing adequate germination or root penetration. Topsoil shall be replaced after grading operations for permanent stabilization. No topsoil is required for temporary stabilization. Tillage implements shall be used as necessary to provide at least a 3 inch depth of firm but friable soil, free of large clods and stones and other debris. All seeding shall be protected by mulching. See Supplemental Specifications for details of permanent stabilization which include spreading topsoil, seeding, fertilizing, mulching, establishment and guarantee. Mulching work shall also be included in temporary stabilization.

B. Seeding Dates 1. Seed shall be applied from April 20 to October 1 for permanent stabilization and from

April 1 to October 15 for temporary stabilization and the seeded areas shall be kept moist for fourteen (14) days to insure growth. If the site is readied for seeding during non-seeding months, it shall be protected by mulching. The site can be seeded later through the mulch. Seeding shall not be done on frozen soil or if the soil is snow covered.

C. Seedings 1. Seed in a moist firm seedbed. Place seed from 1/4 to not over 1/2 inch in depth. See

Table No. 1 for seeding mixture.

D. Irrigation 1. The Contractor shall apply water to the new seedings daily in order to insure that the

seed bed is moist enough to allow germination and growth of the seeds.

3.6 SOD FOR PERMANENT STABILIZATION

A. Site Preparation 1. Fill areas must be compacted enough to resist uneven settling. Cut areas must be

loosened if needed to permit grass root penetration. The entire surface to be sodded shall be free from large clods, stones, or other debris. Immediately before placing sod the soil surface shall be loosened to a depth of one inch and thoroughly dampened if not already moist.

2. See Supplemental Specifications Section for sodding details which include type of sod, fertilizing, sod laying, establishment and guarantee.

B. Sodding Dates 1. Sod shall be applied from May 1 until October 20 and properly irrigated. Frozen sod

shall not be placed nor shall any sod be placed on frozen soil. During periods when sod cannot be laid, temporary stabilization methods shall be applied.

C. Irrigation 1. The Contractor shall apply water to the new sod daily in order to insure that the sod is

moist enough to allow growth.

SECTION 02521

ALKALI-SILICA REACTIVITY (ASR) IN CONCRETE

PART 1 GENERAL

1.1 DESCRIPTION

A. The Contractor shall provide portland cement concrete mixtures for the project that are resistant to excessive expansion caused by alkali-silica reactivity (ASR).

B. The evaluation as to the resistance of submitted concrete mixtures to excessive expansion caused by ASR shall be by the Owner as described herein.


A. This Special Provision is supplemental to all other sections within the specifications of the Contract related to the construction of concrete items for the project.

1.3 SUBMITTALS

A. One week after the Owner awards this project the Contractor shall submit to the Owner all proposed concrete mix designs. These shall include the following: 1. Sources for all fine and coarse aggregates proposed to be used identified by their

MDOT A.S.I # as listed in the Qualified Products List from the current MDOT Materials Source Guide if applicable or by an identifiable name if not applicable.

A. The Engineer shall review the submitted information and testing data submitted with the proposed concrete mixtures and any information and/or any test results with respect to ASR the Engineer has on record for the proposed aggregates and/or proportionate combinations of cementitious materials and aggregates. 1. The criteria for approval of a proposed concrete mixture for resistance to excessive

expansion caused by ASR shall be as follows: a. If a proposed concrete mixture contains cement with an alkali level of less

than 0.60% expressed as equivalent sodium oxide (percent Na2O + 0.658 x percent K2O) the mixture shall be considered to be resistant to the potential for excessive expansion caused by ASR. 1) The determination of the alkali level of the proposed cement shall be

made from the mill test reports submitted per Section 1.03. b. If a proposed concrete mixture contains both fine and coarse aggregates for

which there is testing per ASTM C 1260 that shows that both the fine and course aggregates produce expansions of less than 0.10%, the fine or coarse aggregate used to construct the mortar bar shall be considered to be “innocuous” (per Appendix X1 of ASTM C-33). Concrete mixtures that include both fine and coarse aggregates considered to be innocuous shall be considered to be resistant to excessive expansion caused by ASR.

c. If a proposed concrete mixture for which there is previous testing per ASTM C 1567, shows the proposed combination of cementitious materials and aggregates produce expansions of less than 0.10% the mixture shall be considered to be resistant to excessive expansion caused by ASR.

d. If a proposed concrete mixture for which there is previous testing per ASTM C 1293 shows that both the fine and course aggregates meets the criteria of Appendix XI of ASTM C 1293 with respect to the non-reactivity of the aggregate, the mixtures shall be considered to be resistant to excessive expansion caused by ASR.

e. If, based on the Engineer’s evaluation, additional testing of the fine and / or coarse aggregates is needed to make the evaluations as discussed herein; the Owner shall perform such testing. 1) The Owner shall have access to all materials, including aggregate

pits, in order to obtain samples for such additional testing. 2) The Owner shall perform the following test using the fine and/or

coarse aggregates proposed for each concrete mixture: ASTM C 1260 – Standard Test Method for Potential Alkali Reactivity of Aggregates (Mortar – Bar Method).

3) All samples submitted for testing per ASTM C 1260 shall first be tested to establish conformance to the required material specification for gradation.

4) All samples submitted shall meet the required material specification for gradation prior to being submitted for testing per ASTM C1260.

2. If, based on the Engineer’s evaluation, the submitted concrete mixture does not meet any one of the criteria of 1.05A.1. the mixture shall be rejected or be mitigated by Methods 1. or 2. as follows: a. Method 1. Use of a cement with an alkali level of less than 0.60% expressed

as equivalent sodium oxide (percent Na2O + 0.658 x percent K2O). 1) The determination of the alkali level of the proposed cement shall be

made from the mill test reports submitted per Section 1.03. b. Method 2. Substitution of a portion of the cement with Ground Granulated

Blast Furnace Slag (GGBFS) Grade 100 or 120 (ASTM C 689). 1) For Method 2, the maximum substitution of cement with the GGBFS

permitted shall be 35% by weight of total cementitious material (cement plus GGBFS).

2) For Method 2, the effectiveness of the proposed cement–GGBFS combination to resist the potential for excessive expansion caused by ASR for each aggregate that is considered to be potentially reactive shall be demonstrated.

3) The effectiveness of the proposed cement–GGBFS combination shall be based on test mortar bars per ASTM C 1260 using each fine or coarse aggregate that has been considered to be potentially reactive and the proposed cement-GGBFS combination for the concrete mixture.

4) The criteria for evaluating the mitigation of a proposed concrete mixture with respect to ASR by Method 2. shall be as follows: a) If a mortar bar constructed of an aggregate that is considered

to be potentially reactive and the proposed cement-GGBFS combination produces an expansion of less than 0.10%, the aggregate and proposed cement-GGBFS combination shall be considered to be resistant to excessive expansion caused by ASR.

b) Concrete mixtures that include both fine and coarse aggregates considered to be resistant to excessive expansion caused by ASR by mitigation Method 2. as described herein shall be considered to have been adequately mitigated with respect to and resistant to excessive expansion caused by ASR.

c) If a mortar bar constructed of an aggregate that is considered to be potentially reactive and the proposed cement-GGBFS combination produces an expansion of 0.10% or greater, concrete mixtures containing these materials shall not be considered resistant to the potential for excessive expansion caused by ASR and the concrete mixture shall be rejected.

c. The contractor shall be responsible for all costs associated with the mitigation of a concrete mixture for ASR and any delay costs incurred from the Owner if, due to the mitigation method selected by the Contractor, it takes the Contractor beyond their completion dates.

B. If the Contractor intends to change suppliers or if the supplier intends to change concrete mixtures after the evaluation and/or Mortar-Bar tests are performed, the Contractor shall

ALKALI-SILICA REACTIVITY (ASR) IN CONCRETE CITY OF WARREN 02521 / 4 WWTP – EAST ASH LAGOON RECONSTRUCTION PROJECT


inform the Owner immediately, but not less than forty-five (45) days prior to concrete batching. 1. Upon notification, all concrete work will be postponed, without any additional costs

or extension of time allowed by the Owner, until evaluation of the new mixtures and testing of the new materials, if needed, have been completed.

C. The Owner will be testing the concrete that is delivered to the project site so as to insure that the approved mix design is being followed. 1. To assist the Owner in establishing that the approved mix design is being followed,

the supplier shall include on the delivery ticket for each batch of concrete delivered to the job, the identification and proportions of each material batched.
