The Engineering Contractors’ Association, ECA, since 1976 has served underground and heavy construction professionals in Southern California providing leadership and education on issues important to our member’s success. Working to enhance continued development ECA promotes a healthy construction environment through education of regulatory bodies from the contractor’s perspective and informing the industry on critical developments.

Our Mission

ECA’s mission champions the interest of its members acting as a collective influence in the construction industry in matters of labor relations, government relations, legislative interests and public relations. Membership in the ECA is drawn from 11 Southern California counties and is made up of contractors and affiliates with interests in sewer and water line, storm drain, pipeline, underground utilities, trenching, excavating and grading, tunnels, street and highway construction, water and sewer treatment plants and related engineering construction.

Brendan Slagle, President

One of the first duties of a new president of the Engineering Contractor’s Association is to make sure he introduces himself to members and others in the industry we work on issues, so here goes.

My name is Brendan Slagle. Like many engineers in ECA, I graduated from Cal Poly Pomona with a Bachelor of Science in Civil Engineering Technology in June 1988. By February 1990, I went to work for J.F. Shea where I am a construction manager today, 29 years later.

Over those years, the Engineering Contractors Association was the only group of its kind that I ever paid attention to and have served on the Board of Directors and as Vice President, trying to give back as good as I’ve got from ECA.
