  • Office engineering

About:

This project replaced an existing bridge by installing an 84” reinforced concrete pipe culvert and headwalls below the bridge deck supported by 24” CIDH piles and backfilling with lean concrete around the culvert from the outside edge of the exterior girders up to the bottom of the existing reinforced concrete T-beam bridge deck. The existing reinforced concrete T-beam bridge deck and barriers remained in place and all improvements occurred within the footprint of the existing bridge and public right-of-way. The project also included a mitigation restoration area just downstream of the project site that consists of invasive plant removal and replanting with native riparian vegetation. The project is federally funded and required to follow Caltrans Local Assistance Procedure Manual to manage construction contract.

CPM provided construction management, construction inspection, scheduler review, public outreach, and office engineering.

PROJECT

Portola Road Bridge Rehabilitation Project

CLIENT

Town of Woodside

Services:
  • Construction management
  • Construction inspection
  • Scheduling
  • Office engineering

About:

The project replaced the existing 22’-wide bridge with a new 30’-wide bridge consisting of a prestressed, precast concrete bridge deck and three new abutments supported by 24” cast-in-drilled-hole piles. The new bridge includes a wide shoulder on the south side of the bridge that could be used for a multi-use path in the future. The construction plan was designed to occur in several stages to minimize the necessity for full road closure during construction. All work took place within the narrow 30’ public right-of-way at the project location. The project involved relocation of gas and water utilities by PG&E and Calwater, respectively. The design provided for those utilities to be on the new bridge; however, the connection and utility installation was done by those utilities in coordination with the Town’s bridge contractor.
