The $250 million project was funded with local Measure A dollars, FTA Small Starts Funding, other federal and state monies.
The Leighton Solution.
The project required extensive track rehabilitation, constructing new track, constructing three Stations and expansion and system upgrades on the downtown Perris Multimodal Center. Associated construction includes grading and paving, bridges and drainage structures, upgrading 21 grade crossings, and relocating existing and installing new utilities.
Leighton was chosen to provide quality assurance (QA) geotechnical and materials testing and hazmat review and confirmation sampling. The project involved multiple agencies oversight including Caltrans, RCTC and local cities.
Our quick response to address unexpected construction related issues such as unstable cut slopes along various segments of the alignment and pumping subgrade soils at South Perris Station was critical to the project schedule. Leighton also provided source inspection services and reviewed the Quality Control Plan by the plant manufacturing the precast panels.
