Utility Mapping is an important part of the design phase for any project where excavation will occur. TEC provides underground utility markout services for the design of private and public projects. Our technicians will markout the utilities and locate them with survey grade equipment in the same site visit, reducing field time and costs. TEC provides documentation of utility markouts conducted by ourselves or by others utilizing our UAS or drone systems. With high resolution orthoimagery taken directly after a markout there is no question if something was marked out prior to excavation or not.
