Repair Substation N, Bldg 536

Gilbane repairs electrical substation to support mission critical space launch missions.

Gilbane completely demolished and rebuilt the South Structure and subsequently re-energized it in less than 60 days while maintaining the North Structure at all times. In support of mission critical operations at Vandenberg AFB, Gilbane completed the removal and replacement of the existing Substation N including replacement of the subgrade concrete piles/piers and the replacement of the existing galvanized structural steel substation structures with new stainless steel structures.  The team installed 69kV Group Operated Air Break Switches, Lightning Arresters and 115kV Station Post Insulators. The existing 10 MVA transformers and existing primary circuit breakers remained in place.

Substation N is comprised of two separate structures and electrical components (North Structure and South Structure) that can operate either in parallel or independently.  They serve to support mission critical space launch missions.  As such it is of paramount importance to maintain one of the structures in a fully operational condition at all times.
