The USPS Oakland Processing & Distribution Center is a 1.2 million square-foot facility with a continuous mail processing operation. The Postal Service’s goal for this project was to upgrade the original 1960’s era electrical switchgear without impacting the critical mail processing operations in the building. The project scope included selective demolition, construction of a new structural steel-supported second floor mezzanine, the installation of two 2500/3325 KVA, AA/FA, 12.47 KV-480/277V, and double-ended unit substations. Additional highlights included running new 15 KV conduits and cables to connect to the existing metering switchgear in the basement, the installation of bus ducts from the four new substations to four new 480V switchboard panels, and the installation of emergency generator tap boxes. Construction required close coordination with Postal Service operations.

EPC Consultants provided the Construction Manager for the project.
