Lab 229 is one of more than 40 laboratories in the Field Test Laboratory Building (FTLB) at NREL’s South Table Mountain campus in Golden, CO. As the prime consultant and mechanical engineer, 360 Engineering’s team provided NREL with Architectural and Engineering design services, and Construction Administration Services, for the replacement of 2 stainless steel electric steam boilers in lab 229.
The design team performed field evaluations of existing conditions based on lab use, equipment, and the lab’s functional layout. Removal of the existing utilities included steam piping, drain piping, and feed water piping to the existing boilers. Ceiling tiles were removed and replaced to remove and install new steam piping and new DI piping.
The mechanical engineers designed new steam piping from the new boilers to the existing autoclaves, new drain piping from the new boilers to the existing drains, and new feedwater piping from the main DI building water loop. Electrical design included disconnecting power feeds to the existing boilers and four control circuits and reconnection of power feeds to the new boilers and control circuits.
