Cerrudo Services provided design / build services for the physical plant / boiler room addition to Building 126 at the US Coast Guard Training Center.  The physical plant serves the seven buildings of the H Complex at the Training Center.  Cerrudo constructed the addition, and provided space heating, a steam boiler system and domestic hot water boiler systems with support equipment.  Three boiler/condensate systems, a diesel tank system and hot water tank system were demolished.  Demolition included all unused or abandoned piping, electrical conduit, switches, boxes and conductors.

The single-story 866 SF addition was constructed over a 6” thick concrete floor slab and foundation.  The metal-framed exterior walls were finished with stucco to match the existing building while the interior walls were finished with gypsum wallboard.  A built-up elastomeric roof system overlayed 1-1/2” rigid foam board insulation.  Aluminum painted seamless gutters and downspouts were installed.  Four exterior hollow metal louvered doors and frames were installed.  Work included a propane domestic hot water boiler system and storage tank, propane space heating hydronic boiler and propane steam boiler system in the mechanical building.  The condensate system was installed in the basement of the existing building.  Plumbing work included a stainless steel sink, new mop sink, floor drains and exterior hose bibbs.

Electrical work included new conductors, circuit breakers, switches and conduit back to power panel boards for all new equipment, lighting and receptacles.  The existing space heating pump motor starters were replaced.  A new panel board was installed.  Separate programmable central controllers for each new mechanical system were installed.  A new Class A fire alarm and detection system was installed and programmed.  The new fire alarm panel and devices were tied into the existing Siemens fire alarm system at the Fire Department Building.  The system included heat and smoke detectors, pull stations and light and horn annunciators.
