1 NOTICE OF FOR PROPOSAL AMENDMENT SOLICITATION NUMBER: 36C24123R0112 AMENDMENT NUMBER: 0001 DATE: August 31, 2023 PROJECT NUMBER: 405-23-001 PROJECT TITLE: Water Tank Painting and Repair LOCATION: VA Medical Center, White River Junction, VT 05009 REASON FOR AMENDMENT: Answer RFI Questions 1 thru 2 __________________________________________________________ AMENDMENT: 0001 Question 1 SOW states Contractor shall provide two temporary water storage tanks, each holding at least 6,000 gallons. Tanks shall be piped together and tied into the water service and distribution lines. The temporary water storage tanks shall be able to hold at least 70 PSI of water pressure Using tanks that are 6,000 gals and able to handle at least 70 psi of pressure is tall order. Those type of tanks are very expensive at that size. Is it possible to use static tanks with temporary pumps that could be triggered from the BMS? VA Response:   Yes, that would be fine. The tanks are intended to be used as a temporary tower. The 70 PSI will be maintained with the water pumps in building 2. The VA intends to have the water service flow through the tanks to keep the stored water fresh. The tanks will be wired into the BMS system at the water tower. The BMS is a Siemens Desigo Building Automation system. Question 2 SOW states Water tanks shall be wired into the Building Management System (BMS) to communicate with the two VFD water tower supply pumps in building 2 to maintain a full condition. The water tanks will serve as a temporary water tower, providing an emergency supply of water to the campus in case of any failure by the municipal water system. We are not quite clear on what is needed and how to integrate the tanks into the BMS. What needs to be integrated ? Is it the pressure and / or levels? VA Response:  A level indicator needs to be on the tanks to be sure they remain full.
