1. QUESTION: Can you provide full load amperage for the AHU-34 unit power feed locations?

VA RESPONSE: AHU-34 is fed from 2HNB (400A) shown below and is in Room 1241A. Room 1241A is located on the opposite side of the main entrance hallway, from the Purple Firm, and was the first electrical room on the site visit.

2. QUESTION: Referring to Print #ME-1

a. Coded notes #7 & #8 Can you provide full amperage for the (2) VFD drives?

VA RESPONSE: The project is delegated design. However, the anticipated sizing of the VFD’s would likely be based on the full load of the supply and exhaust fans plus spare capacity (20%) needed to achieve the performance perimeters for the two modes of service.

b. Can you provide location of room 1356?

VA RESPONSE: This is the electrical room in the basement below the Purple Firm and was shown at the end of the site visit. See ME-1 – Basement Level. Room numbers on the plans changed prior to activation.

d. Can you provide location of the METASYS panel?

VA RESPONSE: Room 1249a connects to METASYS and is within the Purple Firm.
