United Airlines Wide Body Hangar Dulles Int’l Airport


Chesapeake Electrical Systems, Inc. provided the Electrical Contracting to build United Airlines Hangar for the new wide body 787 passenger jet, including approximately 21,700 sq. ft. of office space, 10,000 square feet of mechanical and metal shops and over 106,000 square feet of hangar bay area zoned Class 1 – Division 1 Hazardous location. The hangar bay area, over 100 feet in height, is lit with over 150 – 1000 watt metal halide fixtures and features 15 – 400 Hz service pits. Chesapeake Electrical systems worked closely in the beginning of the project with the electrical engineer of record and helped redesign major portions of the one line diagram, evolving the primary electrical service into a 4.0 MVA housed substation.

In effort to offer Archer Western Construction and United Airlines a complete, turn-key installation, Chesapeake Electrical Systems teamed with Global Communications and Evigilent Security to furnish and install all communications, both backbone and plant fiber, and an advanced access control security system along with collaborating with Siemens Fire Safety to furnish, install and integrate the complex dual fire suppression/ foam system which provides fire control/safety throughout the building.
