One Call Systems International

One Call Systems International logo

One call systems process approximately 25 million underground utility locate requests each year in the United States, making them the first step in the damage prevention process. These organizations are much more than ticket processing centers; their staffs create and execute training and educational programs and implement new technologies that make the one call process more efficient for all stakeholders.

One call systems’ staffs provide a key link between national and local damage prevention efforts, which expands the reach of CGA and its programs.

Organized as the One Call Systems International (OCSI) Committee in CGA, OCSI offers a forum for one call system employees and board members to discuss trends from the other CGA committees on a local level. OCSI began as an independent organization in 1985, and elected to join CGA as a committee in 2003.
