RFIs 4-22-2026 - 757-21-101 Replace Roof Building 1A

1. Drawings call to move and put back radio frequency equipment. During work on these areas, is this equipment going to functioning? If so, What happens when we are moving it perform our work. When putting back, is positioning critical for receiving a signal? This should take someone from the VA to position as required. Will the VA be provide coordination with the required technicians?

The radio antennas can be moved and will still operate with no issues. The only item that the positioning is critical for receiving a signal is a small microwave receiver that is for the VA base radio system. If it gets moved it has to be set back up by the company. -VA provided answer.

2. General Note C states to remove and replace plastic drain basket strainers. Detail on AE142 show cast iron baskets. Is there a mix of plastic and cast basket strainers?

We respectfully request the design team to consider/approve PMMA (Polymethyl methacrylate) as a comparable chemistry to the PUMA (Polyurethane methacrylate) waterproofing as specified in specification section 071500 – fluid-applied waterproofing, concrete deck. The chemistries are very similar and applied in the same applications. Attached is a letter from SOPREMA (PMMA manufacturer) along with product/chemistry information for review.

The performance characteristics specified for this project were intended to minimize all odors at the facility. As the product submitted is only a slight deviation from the specification parameters in 071500, product may be proposed for use on-site at Roofs 5, 5A, and 5B, with the understanding that if odors from the product are noticeable during installation, the VA can request an alternative product meeting the specification characteristics provided in 071500 Part 2.1.
