FEDERAL BUILDING - Washington DC

 
 

Cynergy performed a design and build project for a branch of the Federal Government in Washington, DC at a contract value of $2.125 million. The existing building is over 100 years old, space was limited and security was tight. The project had to be approved by the National Capital Planning Commission (NCPC) and comply with the National Environmental Policy Act (NEPA), and DC air emissions requirements.

Principle features of the project were as follows;

  • Provide two 1000KW 480 volt diesel engine generators
  • Provide 480KV paralleling and distribution switchgear
  • Install two remote radiators with intake and discharge louvers
  • Install UL double-wall diesel base tanks with remote fill-port and fuel monitor/alarm systems
  • Provide remote exhaust silencers and piping insulated with a ceramic blanket and rock wool insulation
  • Install feeders in excess of 1000 feet to existing transfer switches throughout the facility
  • Provide new station service panels for the ancillary equipment
  • Installation of interior lighting, sprinklers, fire alarm and ventilation systems
  • Provide a sound attenuated room with doors
  • Painting of the floor, walls, doors, etc.
  • Provide new control systems and connect into the customer’s existing monitoring system
  • Provide new power wiring and accessories for the support equipment

The existing foundations had to be replaced so the new equipment had to be stored in a warehouse until the new foundations were ready. The rigging of the new generators in the hallways were challenging due to the traffic, height and width restrictions of the pathway. The exterior brick/concrete wall had to be saw cut and prepared for the louvers. Structural steel and support columns had to be installed to maintain the integrity of the existing exterior wall structure. A diesel fuel-port was installed recessed into the exterior wall which allows filling of the diesel tanks from the exterior. The louvers and fuel-port were painted to match the exterior wall color.

Miscellaneous installation items included; fuel day tank, batteries, remote radiator circuits and low voltage circuits to the parasitic equipment in support of the generator, control circuits, etc. Commissioning and field testing were a large component in the project. Third party testing was provided for all new equipment, generator and cables. Factory field services were provided for the generator and paralleling switchgear commissioning. Hands on training, classroom training and operation and maintenance manuals were provided for all operational systems.
