Y1DA--NRM-CONST Proj#632-22-900 Upgrade Boiler Plant

ding Services Piping Yes, confirmed for ASME B31.9 Building Services Piping. Work on pressure vessels, Fired and Un-fired, that would require a ASME U, S or R stamp is required to be performed by a contractor that holds a current ASME U, S and/or R stamp under the ASME certification program. 5. Will the mechanical installation contractor be required to hold an ASME U, S, H or R stamp? Yes, confirmed for ASME B31.9 Building Services Piping. Work on pressure vessels, Fired and Un-fired, that would require a ASME U, S or R stamp is required to be performed by a contractor that holds a current ASME U, S and/or R stamp under the ASME certification program. 6. Will hydrostatic testing be sufficient on all pipe welds or will x-ray be required? Some x-ray is required. Refer to spec section 23 21 11 Paragraph 3.3.H for non-destructive examination requirements. 7. Will chemical flushing of new piping systems be required prior to putting system in service? Some x-ray is required. Refer to spec section 23 21 11 Paragraph 3.3.H for non-destructive examination requirements. 8. Will water for hydrostatic testing of piping systems and boiler boil-out be provided by owner? Hydrostatic Testing: Yes � as noted in Section 01 00 00, Paragraph 1.17.F. Water is available at no cost to the Contractor. 9. Can discharge water from hydrostatic testing and boil-out be allowed to go into floor drains or do we need to provide a frac tank. Boiler chemically treated Boil-out Water can be discharged to the site sanitary system. It cannot discharge to the site storm water system. Untreated Hydrostatic test water and flushing water can be discharged to either the Site sanitary or the site storm water system. 10. If X-ray is required, what percentage of welds will require x-ray and who will be responsible for the cost of testing? Refer to spec section 23 21 11 Paragraph 3.3.H for non-destructive examination requirements. The independent testing agency shall be hired by the Contractor. 11. Will tie-in shutdowns need to be done during off hours? Depends on the where the shut-down occurs and the length of time. If the shut-down is required for the entire Facility, it�s generally done during after-hours or weekends. Shutdowns of steam service to Building 92, the VA nursing home may require the contractor to provide means of supplemental heating and/or domestic hot water if a shutdown is required for more than 4 hours. 12. Will building mechanical/boiler room be cleared of all stored debris prior to us entering those areas? The contractor shall provide two (2) forty-foot-long standard metal shipping container type storage containers (placement location onsite TBD) and wood dunnage starting from the installation of the project�s contractor provided temporary boilers installation period thru the end of the Project. The shipping containers shall be placed upon sufficient pressure treated timbers and planking to properly level and support the shipping containers and keep the contents securely above rainwater run-off. The shipping containers are to be in good condition with all gaskets in good condition to prevent water, insect and vermin infestation. Some of the equipment will need disassembly from existing piping, equipment and supports, which will be provided by the Contractor. VA boiler plant operators shall palletize, and plastic wrap the equipment/spare parts/valves/tooling with the assistance of the contractor. The Contractors assistance will include providing labor, pallets, banding and plastic wrap and fork truck services to relocate the palletized materials to the contractor provided shipping containers. At the end of the project, the contractor will again provide assistance to the VA in the form of sufficient labor and fork truck services to relocate the materials, equipment and tooling within the shipping containers into the newly renovated boiler plant or other area VA building. This work will be tracked as a unique series of work activities on the schedule. 13. Pipe Spec on dwg. MP702 references specification 22 31 11 for the soft water piping system. The specification calls for threaded galvanized up to 3�. The valves are called out as carbon steel threaded ball valves. Drawing MP304 shows these valves as flanged gates, please clarify. Are we to use threaded galvanized pipe with threaded flanges with flanged ball valves or gate valves. Or are we using threaded ball valves with nipples to thread flanges. Provide Schedule 80 stainless steel piping for soft cold-water system. Specification 223111 will be updated to reflect this change. Provide carbon steel threaded ball valves as currently noted in the specification. 14. Please provide company and contact info for the BMS contractor in the boiler plant. ABLE Company, Mr. Robert Mangiapia, Phone: 203-876-0636; Cell: 203-520-7693. 15. Can you please issue the pre-bid walk-thru sign in sheet? See attached 16. Please confirm estimated start date for the project. Date is tentatively schedule for August 29, 2025. 17. Can another site visit be scheduled prior to bid date? No. 18. Can the RFI deadline be extended an additional one week to allow sufficient time to review project documents? No. 19. Please also extend the bid date so we have sufficient time to review and prepare our bid after receipt of new RFI responses. RFPs from Offeror�s will be extended to July 14, 2025 by 2:00pm EST.

Please provide additional footing enlargement details at grid F-2 and F-3 where the column footing lies on the building perimeter foundation wall and column pier and how the enlargement must tie into the foundation wall and column piers. See Section 7, Sheet S501. Dowel into both strip or column footing and into pedestal or continuous wall footing @ 8"oc and install rebar + epoxy. New footing will be 2-'0" larger than existing column footing on all sides. 22. Are there As-built drawings of the existing building? See Keynote 18, Sheet C300. 23. Where are the Site Piping Supports located as shown on detail-4 in drawing SB101? See Keynote 18, Sheet C300. 24. There is documentation provided for the Buy American Act. In instances where products or equipment are manufactured elsewhere but assembled in America, does this comply? No. The BAA requires that products or equipment be manufactured in the U.S. to comply with procurement preferences. 25. Does every product (to a certain extent) must be manufactured in America? Yes. 26. What are the instances where a substitute is acceptable? Answered by CO. 27. Are we able to include substitutes in our proposal if certain American Made products have longer lead times than non-American products? No 28. Who is responsible for providing the hoist mentioned on S-501, detail #34. The hoist is contractor furnished and installed. The equipment schedule on AE411 sheet will be revised to reflect this. 29. Please clarify the extent of the slab replacement in the boiler room. See Keynote 03.13, Sheet SB101 and concrete hatch extents on Section 1, Sheet SB101. 30.
