The project involves the reconstruction of the Zerker Road Bridge Abutment in Bakersfield, California, with work encompassing roadway and riverbed excavation, slurry cement backfill, placement of Class 2 aggregate base and hot mix asphalt Type A for repaving the bridge transition, and installation of rock slope protection with RSP fabric. Additional scope includes developing a water supply, implementing temporary traffic control, preparing a water pollution control program, relocating and reconstructing fences, installing a Midwest Guardrail System, painting traffic stripes, and protecting existing utility lines.

The contract is a firm fixed-price construction bid with a 90-working-day completion window from the commencement date, which begins 13 calendar days after contract execution, and work must start within 15 calendar days of that date.
