Design-Build Services - Boiler Modernization - Beltsville, Maryland

BACKGROUND: The boilers at NAL have far exceeded their service life. The original boilers have outlived their original functional provisions and the employees and staff would benefit from a modernization of the boilers to allow for improved heat and hot water function. REQUIREMENT: This requirement is a design-build effort to replace three (3) existing 5000 MBH Boilers with new high efficiency boilers. It will provide the final design to size the boilers, pumps, hydronic system, lay out the equipment and piping, replace the domestic water system, and eliminate the full height boiler stack. Work planned for this project includes installation of new boilers and appurtenant mechanical equipment, piping, accessories, capping of roof curbs, construction of new concrete equipment pads, and infill of opening in existing exterior concrete wall. The work will be completed while the laboratory remains open. The Bridging Documents will consist of a complete 50% design submission.
