Designed and installed temporary fire alarm systems to enable disabling the existing systems in their entirety. Coordinated construction with various commands within each facility.
Replace HVAC System NHB
Code-required modification and replacement of 8 air handling units (AHUs), 15 fans, 8 variable air volume (VAV) boxes, and 16 pumps on HVAC systems serving patient care areas and the emergency department. Extensive phasing, infection control, and outage coordination was required to maintain hospital operations.
Energy Conservation, Phase 3
Design-build energy conservation project consisting of a combination of lighting and lighting control strategies; HVAC optimization via use of VFDs and controls; water conservation measures; point-of-use hot water heating; thermal envelope upgrades; weatherization improvements; and infra-red heating in 36 different buildings.
Design-build replacement of an obsolete quartz halogen backlighting system with a new, energy-efficient LED system for the high-security Main Limited Area (MLA). Design work included engineering and photometrics. Provided new electrical infrastructure to support the four mile perimeter protection system. Phased construction to maintain perimeter protection throughout construction.
Phase II of a campus-wide conversion from centralized steam to building-specific, natural gas powered heat exchangers for hot water and heat generation. This phase involved decommissioning portions of the legacy high-pressure steam system and installating new, gas powered equipment for B6 and B61 and integration into the campus energy management control system.
Repair HVAC Periscope Shop
HVAC system upgrade to meet clean room standards. Scope included selective demolition of existing system; installation of new hot/chilled water generating equipment; air distribution ductwork; control systems; equipment support; electrical power and lighting; installation of a new splined panel ceiling and wall repairs; fire protection system revisions; and commissioning.
Repair Boiler Feedwater System
Phased replacement of three existing boiler feedwater pumps with 4-stage, horizontal, specialty pumps; provision of one spare pump; installation of 300 LF of new, seismically-restrained and insulated 8"Ø ductile iron pipe main and reconfigured header pipe main manifold; variable frequency drives and controls; and flow meters.
VA B100 4E MICU/CCU
Construction of a 12,000 SF Medical Intensive Care/Critical Care Unit in a vacated hospital wing. Facility consisted of 14 patient rooms, 4 isolation rooms, nursing stations, staff conference/break room, administrative offices, and support spaces. Improvements included new mechanical, medical gas, and electrical systems; interior partitions and finishes; service headwalls and booms; and patient lift systems.
B2050 Medical/Dental Clinic Renovation
31,750 SF renovation and 3,500 SF addition to a fully operational Medical/Dental clinic. Scope included total HVAC system replacement, repartitioning, interior finishes, and electrical improvements. Concrete and steel addition provided space for administrative offices and medical exam rooms. Extensive phasing and provision of temporary facilities to accommodate ongoing clinic operations.
Bldg 13 Energy Upgrades
Replaced a legacy chiller unit with a new 200-ton, oil-free frictionless magnetic bearing air-cooled centrifugal water chiller. Coordinated replacement to support the ongoing operations of the research faclities served by the chiller. Scope included piping reconfiguration, integration into the existing DDC system and sequence of operations, and miscellaneous interior improvements to support the work.
