Butier Engineering

About Butier Engineering

For 50 years, Butier Engineering has served as the essential bridge between public infrastructure owners and construction contractors. We were founded on a simple principle: owners deserve a trusted advisor whose sole focus is protecting their investment. What sets us apart is what we don't do. We don't design. We don't build. We manage—with singular focus and zero conflicts of interest. This clarity of purpose has earned us the trust of special districts, municipalities, and public agencies throughout Southern California. Today, with 95% of our work in water and wastewater infrastructure, we bring unmatched construction management expertise to every project. From treatment plants to pipelines, reservoirs to pump stations, we've managed billions in critical infrastructure that serves communities across the region.
