Joint Base Andrews


CSIE was selected by the Department of the Navy to perform all necessary design, engineering, implementation, and construction management of the planned upgrade to the medium voltage electrical distribution system at Andrews Air Force base. The Project scope included the design and construction of medium voltage cable replacement in the flight line areas, replacement of medium voltage overhead distribution with medium voltage underground distribution throughout the command, support buildings, hanger, and residential areas. Electrical design and engineering included short circuit calculations, relay coordination, specification of the medium voltage vacuum circuit breakers and switchgear, electrical cable installation methods and procedures, extensive underground duct bank and manhole system. The project also included the design and construction of a new 2,400 sq. ft. electrical switching facility and the demolition of the existing weatherproof switch enclosure. All work took place while maintaining normal base operations.

CSIE managed the Construction Phase of the project from its on-site trailer with a full-time Project Superintendent, Project Construction Manager, and Project QA/QC Manager. CSIE developed and submitted for approval the required Environmental Protection Plan, Safety Plan and QA/QC Plan prior to the implementation of any construction. The construction management of the project adhered to the U.S. Army Corps of Engineers requirements such as FAR 52.236.5 and 52-236-21 pertaining to Submittals and the Army Corps of Engineers Safety Manual EM385 and OSHA Standards 29 CFR Part 1926.
