Since GM Contracting's beginning in 1973, our focus was mainly the traditional open cut method of installing sewer and water for municipalities. In 1999 we became one of the first contractors in the country to purchase a directional-drilling machine specifically to do sewer and water work. We pride ourselves on being a leader in this exciting industry. GM Contracting is certified as a Disadvantaged Business Enterprise (DBE) and Targeted Group Business (TGB) contractor.
