BART Earthquake Safety Program Parking Structures Retrofit

This project involved concurrent and overlapping retrofits of the parking structures at the El Cerrito del Norte, Hayward, Walnut Creek, Pleasant Hill, Concord, and Daly City stations. The major elements of work included new micropiles, jet grouting of piers, enlarging footings and grade beams, new shear walls in existing structures, fiber-reinforced polymer wrapping, concrete anchors, and steel jacket wrapping of columns. All work was accomplished without closing the parking garages involved.

Services Provided: The Allen Group provided construction management services, including constructability review, readiness review, value engineering, bid analysis and procurement support, construction safety, project communications, document control, cost and schedule management, agency coordination, technical support, environmental monitoring, project reporting, and project closeout.
