Shortly after World War I, President Woodrow Wilson, realizing the acute need for a national cooperative effort on the part of the construction industry, suggested an idea which has matured into a national organization consisting today of over 8,000 general contractors organized into 100 chapters throughout the fifty states and Puerto Rico - the Associated General Contractors of America (AGC).

1922
The MBA is proud to be recognized as one of the founding chapters of the AGC and a part of this huge family of builders boasting a combined annual volume in excess of $100 billion and providing employment to more than 3.5 million workers. Exposure to national construction trends and the availability of AGC resources and contacts help MBA members improve and expand their operations.

1961
The increasing complexity and sophistication of the construction industry created a need for specialized management and jobsite services. The Master Builders' Association incorporated an industry advancement fund into the collective bargaining agreements to further enhance the contractor's competitive stance in the market. This industry fund, called the Construction Advancement Program (CAP), provides professional services in the areas of safety, public relations, legislation, human relations, industry relations, education and apprenticeship.

1985
Promoting industry unity, the MBA expanded its membership to include respected subcontractor groups such as the Master Interior Contractors Association (MICA) and offered its administrative expertise to established organizations including the Tri-State Construction Users Council.

1998
Recognizing the mutual desire to maintain a competitive edge for members, the MBA negotiated an unprecedented 7- year agreement with the Carpenters, Cement Masons, Laborers and Operating Engineers. The Association launched several cooperative initiatives with the trades to promote the value of building with MBA contractors.

Representing Western Pennsylvania's commercial, industrial and institutional construction industry, the Master Builders' Association is the major voice of construction in the region. The combination of MBA services, its administration of CAP programs and national affiliation with the Associated General Contractors of America, assures architects, construction users and developers that MBA contractors provide the best value for the construction dollar.
