The United Brotherhood of Carpenters is one of North America’s largest building-trades unions, with nearly a half-million members in the construction and wood-products industries. We are leveraging our 130-year history to prepare for tomorrow by training, educating, and representing the next generation of construction professionals. Our mission is to stand strong for our signatory contractors and help them succeed in today’s marketplace by supplying them with motivated, knowledgable crews that demonstrate skills, productivity, and a strong work ethic every day.

The International Union of Operating Engineers (IUOE) represents over 400,000 working people across the United States and Canada. Members of the IUOE are primarily operating engineers, who work as heavy equipment and crane operators, pipeliners, mechanics, and surveyors in the construction industry, and stationary engineers, who work in operations and maintenance in building and industrial complexes, as well as a number of job classifications in the petrochemical industry.

The United Association of Journeymen and Apprentices of the Plumbing and Pipe Fitting Industry of the United States, Canada (UA), affiliated with the national building trades, represents approximately 410,000+ plumbers, pipefitters, sprinkler fitters, service technicians and welders in local unions across North America. We also honor a federation agreement with both the Australian Plumbing Trades Employees Union (PTEU) and Irish Technical, Engineering Electrical Union (TEEU). The UA has been training qualified pipe tradesmen and women longer than anyone else in the industry. We provide the premier training programs available in the industry today, including five-year apprenticeship programs, extensive journeyman training, a comprehensive, five-year instructor training program, and numerous certification programs. We help our signatory contractors grow their market share by identifying new opportunities, providing support and connecting them to the safest, most skilled and most highly trained workforce in the industry.
