Boiler Repair

General Description: Building 357, is located at 10215 Brubeck Rd. Fort Belvoir, VA 22060. The building is a testing lab with associate offices for the Research and Technologies Integration Directorate. The building was built in 1965, is a two-story building with large between floor utility spaces and a one-story penthouse level. The building has an area of approximately 101,660 square feet. Existing conditions: B357 is an aging building showing signs of deferred maintenance.

The two-story portion of the building is constructed with concrete masonry units with a brick veneer and has a low-slope gabled roof with a modified bitumen roof finish. The penthouse has a steel frame with insulated steel panel veneer and a low-slope gabled roof with a modified bitumen roof finish. An electrical and mechanical yard is at the south end of the east elevation. This project addresses the steam boiler problems, leaks, and improper function.

There are several obsolete systems (particularly heating) are still present. The steam boiler located outside mechanical room in the boiler room is inoperable. The steam boiler currently serves an HVAC load and a domestic hot water supply load. The intent of this project is to demolish the existing steam boiler and its associated equipment to replace it with 2 natural gas hydronic boilers that meet the HVAC load and provide a separate electric water heater to meet the domestic water supply.
