Provide copper flashing as specified. Spec 07 31 26-4 Snow guards. Who is the manufacturer and what style in copper? Snow guards were not specified for this project. Instead of using felt paper can we install ice and water on the deck instead of felt? It would be more watertight in the end. Yes.

Provide ice and water shield membrane directly to roof decking and as detailed on AS-100. RFI No 2 Section 04 01 00 Maintenance of Masonry describes work involving Repointing existing damaged masonry joints and Replacing existing damaged masonry units. It isn t shown anywhere else in the drawings or specifications the actual scope of this required work. Can you provide clarification to the locations and scope of masonry work required for this project?

Under section 02 82 13.19 Asbestos Floor Tile and Mastic Abatement is a full decontamination unit with shower required for this minimal interior abatement? Contractor to develop and implement a written Respiratory Protection Plan in compliance with OSHA requirements.

Is the VPIH responsible for all flooring and roofing Asbestos abatement visual and air clearance testing or is the contractor responsible for hiring a 3rd party Industrial hygienist for this? VA to provide. Section 02 82 33.13 mentions lead based paint removal but the drawings and specifications don t offer any clarification on this.

Is the contractor responsible for any lead testing or lead paint removal for this project or only the removal of lead lined copper flashing? Lead testing is not required but any paint encountered to be treated as lead paint removal. Would it be possible to have the scaffolding contractor arrive on site and start setting up scaffolding before full contractor mobilization to ensure work can begin and progress uninhibited after full contractor mobilization? Scaffolding is part of contractor mobilization.

The dormers are mentioned in both the specs and the drawings as possible-lead containing paint, but there seems to be no mention of restoring the dormers themselves other than the re-shingling. The dormers are not to be restored on this contract? Dormers to be painted. We saw this was asked in the previous RFI but we would request the VA to reconsider allowing weekend work of an exterior project of this magnitude and complexity.

Allowing the contractor to work when the weather is favorable increases the likelihood this project will get finished in 2024. Is there any roof for consideration of this request? VA will allow weekend work but must be arranged with the COR/ facility. Will the VA require the roofing contractor/ installer to be approved certified EcoStar applicator to install the EcoStar Sustainable Roofing System and offer the Gold Star 50-Year Limited Labor and Material Warranty?

Would the VA extend the due date two weeks? VA has extended bid to May 8th, 2024. RFI No 3 Scaffolding: It is assumed that scaffolding is safety measure required beneath the roof drip edge of each section being worked on. Please confirm. Yes this is correct. There will be additional requirements if contractors wish to move from scaffolding to roof.

Scaffolding will need to be erected on top of the flat roof portions of the building up to the roof edge on the north and south side of the main entrance. Are there any load bearing restrictions that need to be identified? The flat roof is EPDM. The contractor s intent is to lay down a protective barrier (i.e. ¾ plywood) on the roof surface and erect scaffolding on top on the protective barrier. Is this acceptable? There are load bearing restrictions.

Any damage to be prevented and repaired Is the contractor allowed to use concrete anchors into brick-and-mortar exterior to secure scaffolding to building? Upon completion all exterior surfaces to be like before. SHPO restrictions apply. Is the contractor allowed to employ the use of a Hydro Scaffolding type system? This system provides proper safety protection and provides labor crews a more efficient way to transfer tools, equipment, materials, and debris between the ground and the roof. Scaffolding methods are per contractor. Ensure systems meet safety requirements and of commercial quality and availability.

The use of Stainless steel: Plans call for use of stainless steel to be installed for cricket flashing as directed in drawing number AS-100.
