Question
Answer

26.

There appears to be some confusion with the previous RFI’s, specifically numbers 4, 5, 19. The contractors had requested the piping drawings for the replacement of the chilled water and hot water piping systems, but the answer from the VA was to field verify.
Drawing(s) of the existing piping do not exist. Contractor must be in accordance with SOW Section II. D. 8 and Contractor must field verify sizes and dimensions. RFI 4, 5, and 19 responses remain as stated. The Pre-bid site walk through allowed the Contractor(s) time to field verify sizes and dimensions.

27.

Are we adding isolation valves to each line as we complete this work to allow future maintenance and possible total replacement with the need to drain the entire facility?
Replace SOW Section II.D. 1.i) with “Install new heating hot water and chilled water shut-off valves at all branch piping (within 12 inches) from main piping.”

28.

For the base bid, it states: Work includes but is not limited to, replacement of the chilled water and hot water piping systems, the steam to hot water heat exchanger piping system, and the condensate piping system of Building 4. All work shall meet code and be performed in accordance with the contract and any applicable drawings and specifications. The drawings that are provided only show locations for FCU’s, VFDs, and Electrical Panels. The contractor is needing a drawing to show how much piping and valve that will be replaced.
Drawing(s) of the existing piping do not exist. Contractor must be in accordance with SOW Section II. D. 8 and Contractor must field verify sizes and dimensions. See RFI 4, 5, and 19 responses. The Pre-bid site walk through allowed the Contractors(s) time to field verify sizes and dimensions.

29.

What is the Contractor required to furnish for record (aka as-built) drawings?

1.
