St. Elizabeth’s Campus
Balfour Beatty Construction
HGA (Peer Review)
The Central Utility Plant No 2 (CUP2) is a 33,000 sf design build expansion of the existing campus central utility plant serving the St. Elizabeth’s campus of the Department of Homeland Security. The expansion houses equipment to provide 9,100 tons of cooling, 49,500 MBH of hot water heating and 14 MW of stand-by electrical power from four indoor diesel-powered generators. Further complicating the project was that CUP2 was a three-story project built entirely underground.
The KDB team provided engineering, design, coordination, fabrication and installation for the building’s HVAC, mechanical piping and plumbing systems. Working very intently with HGA and Balfour Beatty during both the pre-award and design phases, to improve project efficiencies while reducing costs.
All of the project’s mechanical systems were designed and modeled using Revit, multi-trade coordinated using Navisworks and virtually fabricated using Revit Fabrication software. Additionally, a laser scan of critical parts of the existing central utility building was utilized in the Revit model to accurately coordinate points of interconnection with the existing utilities. Using this technology along with a fabrication quality Revit model allowed for large piping systems to be located and installed with a tolerance of ½” or less from virtual to real world measurement. Laser scanning of newly installed systems to provide the Owner with as-builts far beyond traditional standards.
