a. This question is unclear, what divisions are you talking about? Please send questions to Jeffrey.reed@va.gov

24. When the reference specifications are released, we request you allow an additional 14 business days to the proposal due and allow questions for an additional 7 business days. The additional days for questions will allow our subcontractors sufficient time to review their requirements in the specifications and ask questions which will ensure we provide you with your required product. The additional days for the submission date will allow us to prepare the most responsive, cost-effective proposal, based on the new specification requirements.

44. The completion period of 225 days for this project is too short considering the magnitude of work in both the design and construction. The site investigations, shop drawing drafting, controls engineering, AHU layout, AHU submittal, and submittal approvals will take approximately 90 days. Furthermore, the AHU lead time is approximately 100 days. Considering the above durations, the contractor will be left with only 35 days to install 12 AHUs which isn’t possible. Please consider lengthening the contract duration or issuing an administrative NTP and construction NTP or delay the NTP until the commencement of site construction.
