Utility companies need to know where their lines, facilities and properties are for fast maintenance and repair. Engineers rely on utility mapping for their designs and construction firms know that accurate utility location is important to the health and safety of everyone on site. TEC works with municipal agencies and private utilities to document the location of utilities and easements/right-of-ways by conducting as-built surveys, GIS data collection and detailed property research.  Our experience ranges from transmission lines upstate to the most crowded New York City streets.
