I-5 Widening Project at Florence Avenue 


OE provided construction management and inspection services to the City of Santa Fe Springs for the I-5 Widening at Florence Avenue Phase I Project. Caltrans is currently widening the I-5 Freeway from the Los Angeles/Orange County line to the I-605 Freeway. The existing water mains south of Florence Avenue on both sides of the freeway were in conflict with the proposed sound wall foundations and residential street re-configurations. This project relocated the water mains by installing new 8 inch ductile iron pipes with encasements crossing sewer mains and recycled water lines. It also included installing a 16 inch casing under the freeway and over the top of a 27 inch Los Angeles County Sanitation District Trunk Sewer main. The project installed new valves, blow-offs, air-vacs, and water meter services. The roadway was reconstructed and curbs, gutters, and sidewalks were replaced. This project involved coordination with Caltrans and the cities of Downey and Norwalk to ensure compliance with the plans and specifications. The project required working closely with the utility contractor relocating Verizon conduits.
