QUESTIONS/ANSWERS

Q1. The Specs reference commissioning and commissioning agent but doesn’t specify who will hire the commissioning agent.

A1. VA will hire commissioning agent. HVAC contractor is not responsible for commissioning.

Q2. The drawings show roof curbs being installed. There are no specs for roof work. It is assumed the VA will do all roof patching at the time of the curb installation?

A2. Contractor is responsible for installing roof curb and associated roof insulation (insulation, flashing, sealing, etc.).

Q3. I had our sheet metal contractor reach out with a question on the stainless steel ductwork, I am not sure if you can answer question at this time? It is below in red. It states on spec section 23 31 00-4 (Pharmacy Hood, Exhaust and Associated Ductwork (18 gage) all welded stainless steel. I assume this is all the hatched ductwork on the drawings? There is 3 lab valves on drawing M104 that only serve exhaust air devices. Does this need to be all welded as well or can it be lighter gauge stainless and sealed up to the main? On the all welded construction can the longitudinal seams be welded and the transverse joint connections be vanstoned with steel angle bolted connections where welding the transverse joints is not feasible?

A3. Per VA HVAC Design Manual Nov 1, 2017 Section 3.10 Fume Hood Exhaust Systems, Sub-Section 3.10.4.2 Specific Requirements Paragraph (g): Welded stainless-steel ductwork is required for laboratory fume hood exhaust and biosafety cabinet exhaust systems. Flanged and sealed ductwork is not acceptable on hood exhaust system.
