BART needs increased maintenance capacity as part of its Fleet of the Future program. The Hayward Maintenance Complex will ensure that the maintenance and repair capacity is sufficient to support the new railcar fleet for both the current system and system expansions.

The Hayward Maintenance Complex project consists of acquisition and improvement to four properties on the west side of the existing Hayward Yard for a larger primary repair shop, a new component repair shop, a vehicle overhaul shop, a new central parts warehouse, and a new maintenance and engineering repair shop. It also includes the construction of additional storage tracks for a maximum of 250 vehicles on undeveloped BART property on the east side of the Hayward Yard.

As a subconsultant to AECOM/TSE Joint Venture, OPAC performed structural design of a new 2-story office structure for the Central Warehouse replacement project at BART Hayward Maintenance Complex. The office building will be constructed inside a pre-engineered metal building envelop. The office building is designed as a structurally independent superstructure founded on the same mat foundation of the Central Warehouse building. The structural system for the office building consists of light-gauge metal stud walls and cold formed steel floor joists with steel shear walls and steel sheet floor diaphragms for its own lateral load support.
