With this being an SDVOSB set aside limiting it to only the past three years will severely limit on qualified contractors that cannot submit a proposal. Will the Government please consider the Offeror’s experience in providing construction services as a Prime Contractor for projects completed or ongoing within five (5) years of the posting of the solicitation/RFP? |

42. Our office has reviewed the specifications of the project and noted the following Commissioning Requirements are in the specifications:
01 91 00 General Commissioning Requirements – On Page 14 of the General Commissioning Requirements is a section titled ‘1.7 Systems to be Commissioned’ and below it is a table that references other specification sections.
21 08 00 Commissioning of Fire Suppression Systems 23 08 00 Commissioning of HVAC Systems 26 08 00 Commissioning of Electrical Systems
On page 16, section 1.8.C states ‘The VA shall engage the CxA under a separate contract.’
We also have had inquiries from General Contractors requesting our price for commissioning.
We would appreciate an opportunity to give our proposal for this project and would appreciate any additional information or clarification you could offer.
A. Has the VA has already contracted someone to assist in the Cx process of this project? (or) B. will the Cx requirements be removed from the scope of work?
The VA will create a separate contract for commissioning.
The commissioning specs inform the general contractor of the 3rd party commissioning agents process for verifying that the system will perform according to the construction documents and the VA’s operational needs.
| 43. Regarding the (2) Pressure Powered Condensate pumps, 2-CP-1 and 2-CP-2. Please confirm the capacity requirements for the pumps. Pump 1 is scheduled 40 gpm (20,000lbs/hr) and Pump 2 for 20 gpm (10,000lbs/hr). Is this the total capacity for the duplex package or does each pump need to be rated for the entire load? |
| As part of the revisions, we made one of those pumps a triplex (3 pumps) and the other pump a quadraplex (4 pumps). In the triplex unit, 2 pumps run to maintain full capacity (each sized for half of the load), and the 3rd pump is backup, also sized for half the load. In the quadraplex unit, 3 pumps run to maintain full capacity (each sized for a third of the load) and the 4th pump is backup, also sized for a third of the load. See attached Revised Drawing M-601 rev 2. |
| 44. Does drawing MH104 show the location of all control valves that need to be replaced? |
