Building 10504, 1435 Metzger DR.

Joint Base San Antonio – Lackland, Texas

1.1 PROJECT SCOPE: The contractor shall furnish all supervision, labor, materials, tools, equipment, transportation, incidentals, and quality assurance required for the removal, disposal, and replacement of the existing gas-fired boiler system and associated components in Building 10504, JBSA- Lackland TX.

1.2 BACKGROUND. Building 10504 is a four-story dormitory facility built in 2006, located at Lackland. The gross square footage of the facility is approximately 165,841 square feet (SF). The facility’s HVAC system consists of 264 fan coil units (FCUs) that serve the dormitory rooms, along with four variable air volume (VAV) air handling units (AHUs) and 29 associated terminal units that provide heating and cooling to the building’s common areas.

Additionally, three outside air handling units (OAUs), each equipped with an energy recovery wheel, are located on the attic level and provide conditioned outside air to improve ventilation and indoor air quality. The HVAC system is supported by a 250-ton air-cooled chiller that supplies chilled water to the FCUs, AHUs, and OAUs. Heating is provided by a 4,500 MBH gas-fired boiler that distributes hot water throughout the building and must be replaced.

1.3 SCOPE OF WORK. The objective of this project is to replace the existing boiler system with a new, energy-efficient, code-compliant system that meets the long-term heating needs of the facility.
