Project Duration:
60 days
Project Summary:
The National Institutes of Health (NIH) Twinbrook II project involved the comprehensive renovation and build-out of two decommissioned laboratory spaces, transforming them into fully functional Bio-Safety Level 2 (BSL-2) laboratories designed to support advanced biomedical research activities. The project required extensive demolition, reconfiguration of existing laboratory infrastructure, installation of specialized mechanical, electrical, plumbing, and life-safety systems, as well as the integration of laboratory-grade finishes and equipment necessary to meet stringent BSL-2 containment and operational requirements. A significant challenge of the project was that all construction activities were performed within an occupied and fully operational NIH laboratory facility. Careful planning, coordination, and phased execution were essential to minimize disruptions to ongoing research operations, maintain safety and security protocols, and ensure continuous facility functionality throughout the construction process. The successful completion of the project provided NIH with modernized laboratory environments that met current regulatory standards while supporting the agency's critical scientific mission.
Doyle Systems' Scope of Work:
Doyle Systems led the mechanical and plumbing scope for the conversion of two decommissioned NIH laboratory spaces into new Bio-Safety Level 2 laboratories. Work included demolition of existing piping and ductwork, installation of new HVAC and plumbing infrastructure, and the startup, refurbishment, and re-commissioning of two rooftop air handling units and two rooftop exhaust fans. The completed systems supported new exhaust ductwork, supplementary chilled water fan coil units, hot water duct coils, CO₂ and natural gas service, reverse osmosis water, compressed air, vacuum piping, 10 laboratory casework units, and 4 Bio-Safety cabinets.
