About Us

Our Mission


The Carpenters/Contractors Cooperation Committee (Quad C) is a non-profit organization established pursuant to the Federal Labor-Management Cooperation Act of 1978 (29 U.S.C Sect. 175a) and committed to quality development and quality construction jobs.


For over 30 years, the Quad C has collaborated with local, state and federal civil and criminal law enforcement agencies to crack down on unlawful business practices that hurt responsible contractors, workers and communities. The Quad C is also now authorized in California to file direct legal actions against general contractors when their subcontractors violate labor laws on private construction projects. This is a powerful enforcement tool to promote compliance, fairness and high-quality standards


The Quad C monitors hundreds of projects, ranging from public works, affordable housing to multi-family residential. From case filing through planning and entitlement, we actively participate in the development process. Once projects are in the construction phase, our team vigorously monitors projects to ensure compliance with the law.


Additionally, we are engaged in industry research and educational efforts, as well as in local and state policy and legislative affairs throughout the Southwest.
