Document Description
Caltrans proposes to repair six (6) culverts via CIPP (Cured-in-Place-Pipe Liner) and repair headwalls via concrete spall repair in Imperial County on SR 111 at various locations from 0.9 miles south of Range Road to Range Road. This project will not require temporary construction easements, permits to enter, or permanent acquisitions. This project will include shoulder, lane, and/or ramp closures to allow sufficient space for the contractor to access the culvert end treatment (aka drainage inlet, etc.). No detours are required for this project. CIPP liner involves inserting a flexible liner into the upstream culvert end treatment, which is then pulled through to the downstream culvert end treatment. The CIPP liner is then inflated and cured to harden the liner. Headwall repair will be via concrete spall repair, which will consist of a superficial layer of concrete on the headwall to patch cracks or spalling. No construction equipment is required for the headwall repair. Work adjacent to the culvert end treatments will be limited to workers on foot with hand tools only. Equipment will be parked on the paved area and is limited to a vactor truck to clean the culverts, CCTV/Cure truck for video and curing of culvert, and service truck for unrolling liner. Access will occur on travelled way. Temporary impact areas will be limited to the culvert end treatments. All work will occur within Caltrans state right-of-way.
