JFSD230068 REPAIR HVAC SYSTEM HYDRANT FUELING B658

Added Questions and Answers. 6 Feb 25 The Architect-Engineer (A-E) shall perform field reconnaissance, studies, site investigations, and a preliminary design meeting with the users, including travel and work required to obtain engineering information and design data to produce contract documents for this project. The Base Civil Engineering Project Manager will assist in scheduling design meetings.

Building 658 is a 3800 sq ft hydrant fueling facility for jet fuel and includes significant fuels piping fed from the nearby outdoor storage tanks. Most of the space in the facility is a fuels piping bay. There is also a small control room and bathroom in the facility. The heating in building 658 is inadequate to maintain heat in the fuel bay. The bay is currently heated by 4 hydronic unit heaters, supported by a 400 MBH boiler which also supplies heat to the rest of the facility.

The fuels piping bay eye wash station does not have sufficient accessible hot water. Current domestic hot water is supplied by a small on demand electric hot water heater, which appears to be inadequate. The fuel coming from these outdoor storage tanks cools the space when operations commence during winter months, providing additional heat load.

The small control room and bathroom are not included as part of this project, though the heat load from the air handler and bathroom in this area will have to be considered for boiler sizing. Historical drawings for this facility have been lost. Site investigation and measurements will be critical to the success of this project.
