Access to the school, particularly the interior of the building will need to be carefully coordinated with Michael (Tony) Franco.

Port Orange Elementary School Repair & Coat Roof – Bldgs. 1 and 2 Pre-Bid Meeting Minutes July 20, 2021 A/R/C Project No. 20049.00.00 Page 2

b. The contractor is able to work 7-days a week as they deem necessary, some

night/early morning work will be allowed. Application of finished roof system is limited to daylight hours due to safety and application quality concerns. The school staff and the facilities department will make whatever arrangements are reasonable and necessary for access to the facility. Access to the interior of the building must be limited to hours when no students or staff is present.

c. All workers on-site will be required to be registered with Volusia County Schools, and have company issued identification shirts or badges. This issue was further defined by Tony Franco, the on-site superintendent will be responsible for the daily log in regards to the workers on-site each weekday.

d. The Instructions to Bidders, and the General Requirements contains detailed instructions as to the overall project and the bidding requirements. The bidders should examine these sections carefully. When completing the subcontractor list, write “N/A” next to any category of subcontractor not used, or write in your own company if the work is self-performed. There is no Bid Bond or Performance and Payment Bond required for this project.

e. The contract for construction will be based on the “Owner-Contractor Agreement”,

AIA Document A101-2017, a copy of which have been included in the project manual for the bidders’ reference.

f. The successful bidder will need to be pre-qualified with the school district prior to

bid submission, this may be accomplished by contacting Erika Cortez with VCS to determine eligibility and procedure at 386-947-8786. If not already pre-qualified and current with VCS, this will not be possible prior to the Bid submission date for this project.

g. The School District has the option to utilize an Owner Direct Purchase program for the roofing materials, although it is unlikely due to the size of the project. If utilized, it would be done according to the procedures defined within the general conditions included in the project manual.

h. Section 02025 is “Existing Conditions” (follows General Conditions and associated

attachments) and includes information gathered during our field investigation, including roof cut data for the roof areas designated for roof replacement. We have also included a link to a website with our field investigation photographs.

i. Section 01010 is a Summary of Work and includes a detailed description of the work involved with the roof replacement and repair work at this facility. This should be carefully reviewed by each bidder. 1. Existing gutters, leader heads and downspouts are to remain in place. Test

downspouts and spillways for proper operation. Clean and correct any drainage issues discovered.

2. Existing lightning protection system to be partially removed only when applying coating application and reinstalled. Re-attach the system where it has become detached from the roof system throughout.

3. Identify areas of water intrusion with damaged insulation / leaks - Cut membrane and remove wet rigid insulation down to structural deck. Field verify extent of damage and replace with new rigid insulation per unit price allowances, match

Port Orange Elementary School Repair & Coat Roof – Bldgs. 1 and 2 Pre-Bid Meeting Minutes July 20, 2021 A/R/C Project No. 20049.00.00 Page 3

existing thickness and slope. Replace modified membrane system with new and strip-in to existing per the unit price allowances.

4. Remove existing counterflashings along wall and chimney and rework base flashings per project details. Reinstall existing surface mounted counter-flashings per the project details, secure with new neoprene backed fasteners, and apply new sealant.

5. Cut back existing roof membrane at drip edge and apply new liquid flashing compound to seal membrane-to-metal connection per the project details.

6. All soil stack/ventilation stack flashing to have lead flashings replaced with new #4 lead flashing “boots”. Repair modified bitumen flashing at penetration per project details. Replace existing pest cover, secure with fasteners as required.

7. Prior to coating application, identify areas of standing water and feather in additional layers of modified bitumen membrane cap sheet to create positive drainage to perimeter edge.

8. Upon completion of all repairs at the existing modified bitumen roof and flashing system, power broom and vacuum existing roof surface to remove loose granules, then prepare surface and apply a reflective fluid applied silicone coating to all modified bitumen surfaces per the manufacturer’s directions and the project specifications.

a. Provide an alternate cost for the application of fluid applied polyurethane based coating in lieu of the silicone – see section 01023 Alternates.

9. Clean and restore site to pre-project conditions as directed by the Owner..

j. Within Section 01010, there is a project rain day form that needs to be filled out for the month. Rain days need to be verified and signed for by either an Owner’s Project Representative, or the Architect’s Representative. This rain day form should be submitted with the monthly payment application from the contractor in order to claim a time extension due to weather conditions within the current payment period. Retroactive requests for raindays for previous payment periods will not be considered. This form should also be used to document any days when work is restricted by the Owner, such as FCAT testing.

k. Also within Section 01010, there are both Interior and exterior inspection forms which should be filled out with the representative of the Owner. There should also be a digital video file produced and digital photographs taken; submit copies of all this data to the architect prior to start of construction. These measures are to document the interior and exterior conditions prior to the start of construction as protection for both the Owner and the contractor so conditions prior to construction can be verified at a later date.

l. There is currently one alternate prices requested for this project defined in section 01023, no voluntary alternates submitted by the bidders will be considered.

m. Section 01026 includes four (4) unit prices, which are oriented toward repairs of and

corrections to existing materials which may be discovered to be deteriorated or damaged, such as wood blocking, modified bitumen membrane, tapered insulation and edge metal. These unit prices are also defined within the bid form, base bid quantity allowances are included in the bid for these repairs and replacements.

Port Orange Elementary School Repair & Coat Roof – Bldgs. 1 and 2 Pre-Bid Meeting Minutes July 20, 2021 A/R/C Project No. 20049.00.00 Page 4

n. These unit prices are intended for the replacement of deteriorated and/or damaged existing materials intended to remain. The installation of any materials designated as “NEW” within the project documents either by words, symbols, or graphically is not to be considered part of the unit price usage. The actual location of their use will in part be determined in the field based on actual conditions. Any use of these allowances must be approved by the Owner and/or Architect, as well as documented in daily reports and with photographs.

o. The requirements for application of payment are included within Section 01027.

The contractor is to utilize an AIA G702 Application for payment and an AIA G703 Continuation Sheet. At least one (1) each of those forms will be in “red type original”. Others may be copies. The continuation sheet shall reflect each discipline of the job and be broken down by labor and materials, per building to allow the contractor’s application for payment to be reviewed and approved quickly.

p. Signed and sealed documents have been submitted to the VCS Code Enforcement for their review, and all technical comments have been satisfied, the Contractor is responsible for submitting any additional information for permit, (such as licenses, insurance forms, product approval data, etc.), and obtaining the building permit. There is no cost associated with the issuance of the permit by VCS.

q. The contractor should be aware that VCS Code Enforcement will be actively

involved in the oversight of this project, they have specific inspections that must be made, and careful coordination with their requirements is necessary. They are on a 5 day work-week during the school year and a Monday – Thursday during the summer, but can perform weekend inspections if absolutely necessary with adequate notification on a case-by-case basis.

r. Within section 01010, several of the permitting submittal requirements for the

contractor are defined, such as license, insurance certificate, barricade / safety plan and Florida product approval documentation. It is the contractor’s responsibility during bidding to coordinate the products and manufacturers selected to provide a complete system from existing deck to the finished roof that has the appropriate approvals which is acceptable to the VCS Code Enforcement and can be permitted.

s. Volusia County Schools Code Enforcement will require the contractor submit a barricade plan, and it will need to be updated as the work progresses. Contractors will need to be aware that the cost will need to be reflected in their bids. It is typical to allow for the use of orange fencing for cordoning off work areas and the use of chain link for equipment and dangerous items.

t. The bidders are welcome to visit the project site after this pre-bid meeting or during the bid period. They were directed when on site they will need to notify the facility administration, “sign-in” when they arrive, and “sign-out” when they depart and provide evidence of compliance with the Jessica Lunsford Act.

5. Drawings are only available in a digital format and may be downloaded from the VCS

website via the internet free of charge as defined in the Advertisement to Bids. Any photographs taken by our office during our field investigation are available through an internet link to the website containing the photographs, which is the following:

Port Orange Elementary School Repair & Coat Roof – Bldgs. 1 and 2 Pre-Bid Meeting Minutes July 20, 2021 A/R/C Project No. 20049.00.00 Page 5

6. In regards to the issue of the storage and staging area, Tony Franco noted that available areas can be coordinated with him and the building administration. There are several areas that could be used for storage with proper coordination, which can be finalized at the pre-construction meeting.

7. A primary concern will be at all times to not impede any paths of emergency egress, nor

interfere with the activities of the facility when occupied. The contractor would be expected to take proper precautions.

8. The contractor will be required to repair any damage to the site and landscaping to restore

pre-project conditions upon completion of the work.

9. The Owner will allow incidental use of on-site 120 volt electricity and water by the Contractor, unless this privilege is abused, in which case the contractor will become responsible for their own electric and water supply. Temporary toilet facilities are also the responsibility of the contractor.

10. The general conditions state that no roofing work can be performed above occupied space;

the way this has been enforced is to perform demolition and installation of the waterproof underlayment over unoccupied space. Typically, when buildings have suspended ceilings, roofing work has been and will be allowed once the underlayment is in place. No loading of the roof or crane operations are to be performed over occupied spaces.

11. The areas and dimensions shown on the plans are the result of our fieldwork and

information provided by the original design documents; represent level footprint areas and dimensions, and do not account for slope. The contractor is reminded that General Roofing Note "1" on drawing B01 requires the bidders to perform their own fieldwork upon which to base their bids.

12. The Bid date can not be extended, the bid date was established based on deadlines for the

school board meetings, and there is no flexibility for change without impacting the overall project schedule defined by the school district.

13. A sign-in sheet was passed around for each attendee to sign, a copy of which will attached to the Pre-Bid Meeting Minutes to be issued with the first project addendum. It is important that a valid email address be provided; notification of the project Addenda and meeting minutes being posted to the Internet website will be distributed by email only.

14. The final addendum for this project (if required), due to the bidding schedule, will be issued

by our office on Wednesday July 28, 2021 to address any remaining concerns. All addendums will be sent directly to the bidders via email by A/R/C Associates, it is suggested that all bidders check the VCS website up to the time of bid submittal for any additional information for this project.

15. Questions from the Bidders (and frequently asked questions): a. Is Tuesday, July 27 also the deadline for any substitution request submittal prior to

bidding, such as an alternate coating system? Answer: Yes, July 27 is the deadline for questions and substitution requests.

Port Orange Elementary School Repair & Coat Roof – Bldgs. 1 and 2 Pre-Bid Meeting Minutes July 20, 2021 A/R/C Project No. 20049.00.00 Page 6

b. If the existing lightning protection is partially removed and hen reinstalled, does it need to be recertified upon completion? Answer: Yes, we typically require a UL Letter of Findings.

c. Do portions of the lightning protection system need to be removed along the edge of the roof to perform the work specified? Answer: Yes, considering the membrane needs to be cut back 1” and liquid flashing compound applied.

d. Is correction of the areas of ponding water included into the scope of work and/or the

unit price allowances? Answer: Yes, the addition of additional plies of membrane or application of a cementitious filler (such as RoofSlope) should be included into the base bid scope of work, the application of a finished cap sheet over these areas would be applied under the unit price allowances.

e. Are the wrinkles in the valleys at the original building to be corrected? Would this work be under the base bid, or the unit price allowances? Answer: Yes, these wrinkles would be considered “defective” areas in the existing roof membrane and corrected under the unit price “B” allowances.

f. Are there any repairs being made to control the membrane movement / sagging being experienced due to the roof slope at several sections of the older roof area? Answer: Yes, we have defined the addition of fasteners and stress plates as “Specific Plan Note #5”, which is then covered with a strip of membrane. Although this appears to limited to part of a hip and transition, which may need to be clarified.

We believe the above accurately records the Pre-Bid meeting and briefly outlines the items of discussion. Unless contacted prior to 5:00 pm, Tuesday July 27, 2021, we will consider the above correct. These minutes, and any clarifications or revisions contained therein, are to be considered a part of the bidding documents for this project. Respectfully submitted, James W. Ripley, Vice President RA, NCARB, RRC, RWC, REWC, RBEC, RRO, REWO

PART 3 EXECUTION

3.1 INSTALLATION

A. Install in accordance with NFPA 780, UL 96A, and LPI-175.

B. Connect conductors using mechanical connectors and/or an exothermic welding process. Protect adjacent construction elements and finishes from damage.

C. Bond exterior metal bodies on building to lightning protection system and provide intermediate level interconnection loops 60 feet on center.

D. During installation, no penetration is permitted of the metal roofing system and/or flashing components by mechanical fasteners unless specifically detailed within the project documents; epoxy adhesive attachment of the base and anchor plates is required otherwise.

E. Where any part of the protection system is exposed to mechanical injury, it shall be protected by a nonconductive material. If metal pipe or tubing is used for protecting conductors, the conductor shall be electrically connected to the pipe or tubing at both ends. Conceal down conductors in PVC (Schedule 40) conduit.

F. Where necessary, connect copper equipment to aluminum surfaces using UL recognized bimetal transition fittings. Lead coating is not acceptable as a bimetal transition fitting.

G. Roof Conductors: A perimeter cable shall be installed around the entire main roof areas, and all penthouses. Each perimeter cable shall be connected to at least (2) down leads, providing a two-way path to ground for each air terminal. All center roof air terminals shall be interconnected with conductors to the outside perimeter cable. Conductors on the flat roof areas may be run exposed. Ground connections shall be made around the perimeter of each roof and to the main down conductor at a maximum distance of 100'-0" on center.

H. Down Conductors: Existing shall be used where properly tested and approved for UL labeling. New down conductors, if required, shall be concealed and installed in 1" PVC (Schedule 40) conduit. Each perimeter roof cable shall be connected to at least two down leads. The average distance between down leads shall not exceed 100' from upper roof to lower roof, or from roof to ground terminals. Irregularly shaped structures may require extra down conductors to provide a two-way path to ground from each air terminal.
