Plano Street Bridge Widening & Street Improvement Project

City of Porterville | 2013 -2015

VSCE provided construction management and resident engineering services for an $11M bridge widening and street improvement project for the City of Porterville.

The project was funded by federal funds administered by Caltrans Local Assistance and consists of widening the existing Plano Street Bridge from two lanes to four lanes and includes the reconstruction of the street approaches. The project is located in the southeastern portion of the City along South Plano Street, crossing over the Tule River. The existing bridge consists of a reinforced concrete tee girder superstructure supported by pier walls and is made up of sixteen spans with a total length of approximately 178.7 meters. The bridge widening consisted of a reinforced concrete tee girder superstructure supported on pier walls. The reinforced concrete piles support the pier walls and abutment walls. The pier walls and abutment walls of the bridge widening are supported by driven steel piles. VSCE was responsible for the full scope of construction management that included construction administration in accordance with Caltrans LAPM, quality assurance and inspection of field activities, management of project finances, control of project budget and schedule, resolution of day-to-day issues and coordination with the utility agencies, design team, City of Porterville, and the public. The Tule River had difficult piling conditions and a longer bridge. Two additional bridges were built, then connected to the old bridges on both sides.

BUDGET CONTROL: The project was completed with less than 8% in contract change orders and no outstanding claims. Significant enhancement change orders were owner initiated to improve the access to local business and rehabilitate the roadway to the bridge approaches.
