Project Description
This project involves the demolition of the existing bridge and construction of a new, Caltrans MASH-compliant bridge over Oak Creek, completed in 5 stages. Road 427 will remain open to one-way reversing traffic during Stage 1, aided by a temporary signal system, timed to coincide with the near by high school. The remaining stages will maintain two-way traffic and pedestrian access. Stage 2 includes relocating a County sewer line with new manholes and encasement across Oak Creek. The superstructure will consist of 13 precast, prestressed voided slabs with a 7-inch cast-in-place reinforced concrete topping slab. CCME will oversee field inspections, documentation, claims, and quality assurance, including source inspection and coordination with the County’s testing lab.

Services Provided
Services include but are not limited to: documentation of preconstruction conditions, weekly progress meetings and coordination, submittal management and review, RFI management, construction inspection, progress payment estimates, QA material testing oversight, change order negotiation and writing, and project closeout, including final acceptance.
