The renovation of the E-Wing in Building 10 represents a conversion of 15 floors, totaling approx. 255,000 GSF comprised of former patient care, laboratory areas, and support space spread over 15 floors. The new spaces will include clinical program area, cGMP production facilities, research laboratory, lab support, teaching facilities, office space, and building support space for approximately 800 personnel in the clinical research programs, which incorporate specialty lab programs that support the Clinical Center’s Transfusion Medicine Program’s (DTM) patient and donor apheresis, and BSL-2 laboratories currently housed in the West Distal Wings for clinical research programs. CFR was brought onto this project after the design was completed to provide our plumbing and fire protection expertise. CFR is completing construction administration services in lieu of the Engineer of Record.

This project was a design-build project. CFR was the MEP Designer of Record for this project and worked as a sub-consultant under the Prime Architect. The project included MEP engineering and construction administration services for the design of a new building for the National Institute on Aging – Center for Alzheimer’s and Related Dementias (CARD) Temporary Research Facility. The new building is 24,000 square foot single-floor facility housing BSL-2 laboratories, other laboratories, support areas, a break room, breakout areas, huddle spaces, conference rooms, and open and private office spaces. Penthouses above the first floor were designed to house MEP equipment.
The lab spaces include four (4) tissue culture labs, two (2) optics labs, two (2)multi-flex labs, and one (1) open lab. Other spaces include lab equipment rooms, freezer room, and autoclave room.
The project won ENR 2023 MidAtlantic’s Best Project Award for Higher Education/Research.

This project included mechanical and electrical engineering design services for the design of a trailer mounted chiller, pumps and power system which will be used as a portable chiller plant for the Naval Surface Warfare Center IHD buildings. Design included a nominal 150-ton air-cooled chiller, pumps, VFDs, controllers, electrical panels, and a transformer. This system is used with water or Propylene Glycol solutions up to 40% PG. The design accommodated all components on the trailer in a way that facilitates access and removal of equipment as necessary and provides flexibility in the number of pumps used at any one time.
CFR designed the trailer mounted chiller in BIM 360 for precise construction from the design documents. The 3D BIM rendering can be compared to the finished product in the "MORE PHOTOS" link below.

This project was a design-bid-build project through CFR’s A/E IDIQ at NIST. The project included the replacement of the main electrical distribution equipment within Building 220 and Building 301. Eaton network transformers, CM-52 draw-out type network protectors, and switchgear were provided. Switchgear featured internal collector bus with electronically operated and metered circuit breakers integrated into the buildings’ existing Foreseer metering system. Addressable relay modules were provided to monitor high temperature sensors in network transformers, positions of network protectors, and position of main and tie breakers in switchgear for comprehensive monitoring of the equipment status.
In Building 220, three new 15kV fused load interrupter switches, three 1,000kVA, 13,800V:480/277V network transformers, busduct, and a Main-Tie-Main-Tie-Main-Tie network switchgear were designed to replace equipment within the penthouse. Detailed phasing of work reduced building outages and involved the provisions of dead break connectors in the basement to eliminate the need to access electrical manholes. The phasing plan permitted the building to operate on two of the three network transformers while new transformers were installed, tested, inspected, and re-energized to normal operations
In Building 301, three new 1,500kVA,13,800V:480/277V network transformers, busduct, and a Main-Tie-Main-Tie-Main-Tie network switchgear were provided. The network transformers and switchgear were closely engineered to upsize existing equipment providing additional capacity to the facility. Short circuit studies were performed to verify the design maintained the existing fault current conditions seen by downstream equipment.
Both facilities required careful planning of the phasing of work, equipment travel pathways, and coordination of site locations for crane picks to facilitate the removal of existing equipment in a safe and effective manner.

This project was a design-bid-build project through CFR’s A/E IDIQ at NIST. The project included replacement of multiple Custom Air Handling Units (AHUs) and Fans in two buildings: Building 101 and304. Within Building 101, there were (6) AHUs replaced, as well as (9) fans. Within Building 304, there were (7) AHUs replaced, as well as (23) fans.
In both buildings, custom AHUs were provided with steam heating and chilled water cooling, with zoned reheat. Steam traps were provided, as well as steam condensate piping. New controls sequences were designed, and components of existing controls were removed. The design included electrical power connections for all of the equipment listed above. The new power feeders were provided from existing electrical equipment. The design reviewed the existing electrical equipment to confirm the equipment was properly sized to serve the new mechanical equipment. The electrical design included new variable frequency drives for the AHUs and Fans. The equipment was provided with VFDs for increased energy efficiency and operational requirements.

Project include architecture, structural, mechanical, electrical, plumbing, and fire protection engineering design for to upgrade the interiors and replace the HVAC system of the Training Building as well as replace the roofing on the Battalion Maintenance Activity (BMA)building on the U.S. Army base in Fort AP Hill, Virginia.
Training Building: The major component of the scope was to replace all base building HVAC equipment serving the building. Design included replacement of all major pieces of equipment including three (3) new roof top air handling units (AHUs), new exhaust fans, new ductless split system, new DX split AHU. All new air inside the building was provided by new air terminal units with electric reheat. Design also included propane gas piping from existing propane tanks to the new RTUs as well as new power for all new mechanical equipment. For the high occupancy assembly training area, CFR designed the CO2 sensors and demand-controlled ventilation as required per code. There was also a task to complete the interior upgrades of the building started by another contractor. This included furnishing and installing gypsum board walls and ceilings, insulation, interior finishes, doors and door frames, door hardware, tiles (shower areas and vestibules) and installing previous items stored in a storage container within the building.
Battalion Maintenance Activity Building: Design included replacement the existing standing seam metal roof and all associated pieces including clips, trim, ridge vents, flashing, curbs around ducts, eaves, and facia. Gutters, downspouts, and insulation were also removed and replaced. One of the major challenges in the project was to meet the various code requirements as directed by industry standards and the US Army Corps of Engineers which is Authority Having Jurisdiction on the Army base.
