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.

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 12 Southern California counties and is made up of contractors and affiliates with interests in sewer and water line, stormdrain, pipeline, underground utilities, trenching, excavating and grading, tunnels, street and highway construction, water and sewer treatment plants and related engineering construction.

Under the guidance of ECA’s board of directors operations staff includes Executive Director Ray M. Baca, Office Manager Sheila Voss, Administrative Assistant Paulina Gilles-Pantoja and Magazine Editor John Simpson.

ECA Membership Classifications

ECA Memberships are made up of two categories: 

  1. Contractors are signatory to the Master Labor Agreements covered by the ECA, or are independent.
  2. Affiliate Members manufacture, supply, service, and/or distribute materials or services used by contractors involved in the general and underground construction industries.

Government Affairs

As a basic element of its long range planning efforts, ECA maintains both a Political Action Committee and a Government Affairs Committee. These two bodies of the association work in conjunction with each other and strive constantly to ensure that public policy which could adversely affect construction is either blocked or modified.

They diligently work toward the goal of implementing favorable public policy so that members may enjoy a more successful and profitable business climate.


Additionally, ECA works closely with labor unions to provide the most direct individual representation of union contractors’ labor relations available. The ECA Labor Committee’s responsibility is to gather, evaluate, and disseminate labor information affecting contractor operations. The committee also negotiates Master Labor Agreements with the five basic crafts: Carpenters, Cement Masons, Construction Laborers, Operating Engineers, and Construction Teamsters.

Membership Meetings & DIG Award 

Monthly membership events, featuring industry experts, are the basic meeting grounds for members. The association also holds its golf tournaments for the benefit and enjoyment of members. The DIG Award, ECA’s most prestigious event, is presented annually to individuals of Dignity, Integrity & Generosity DIG in underground construction. This black tie affair presents a gathering of industry greats and recognizes recipients for their achievement. 

ECA Magazine

Keeping members informed on issues both within the association and the underground and general construction fields, ECA publishes its monthly magazine distributed industrywide to construction professionals.

Safety Forum 

ECA promotes worksite and job safety through informative presentations, webinars and member messages. ECA’s Safety Forum serves as a liaison with the various occupational safety and health agencies such as OSHA and Cal/OSHA.

APWA & Public Agencies

ECA members serve in the APWA (American Public Works Association) committee for the membership in improving and streamlining the Standard Specifications for Public Works Construction (known as the Green Book), plus all new specifications, materials, sewer and drain design, compaction requirements, and related regulations. 

It is the Association’s intention that once a contractor receives a contract, he will be able to work efficiently and, most important, cost effectively within the specifications required. The strong voice that ECA has earned within the construction industry has placed the association in a respected position. ECA provides constant input and represents member’s most important interests before agencies, legislative bodies and regulatory entities. Dedication and commitment to individual member needs have been key to ECA’s and its member’s success.
