Associated Builders and Contractors San Diego protects free enterprise and contractors' rights to work and bid in a process that is competitive, fair and open. The organization's membership grants access to networks that'll help grow businesses. Aside from meetings with owners of businesses, membership also enables access to Jobsite123.com, a national database replete with names of contractors used by general contractors and owners who are searching for qualified workers for projects. Because the group strives to aid its members in delivering work that is safe, ethical and profitable, the organization offers apprenticeship training, which covers five trades -- electrical, plumping, pipefitting, electronic systems and sheet metal.
