Big Ben Engineering Tackles Major Orange County Sewer Infrastructure Upgrade
Featured on the cover of the 2026 Underground Construction issue of CalContractor Magazine, Big Ben Engineering took on the Orange County Sanitation District's (OC San) $25 million Taft Branch Improvements project in the City of Orange. The project involved replacing and expanding aging sewer infrastructure to improve system capacity and reliability.
With excavations reaching depths of up to 20 feet, Big Ben Engineering utilized trench shields and other shoring systems supplied by Trench Shoring Company. The extensive work required careful coordination of sewer bypass operations, traffic management and underground construction while maintaining uninterrupted service.
The project presented significant challenges, including working along heavily traveled streets, coordinating with multiple agencies and utility owners, and maintaining sewer service throughout construction. Big Ben Engineering's careful planning and experienced crews helped bring this critical infrastructure upgrade through its major construction phase.
As Project Manager Cesar Miranda explains, “Trench Shoring Company has always been extremely professional and responsive whenever we need something.”
