Our professionals are experienced with the use of ground penetrating radar (GPR) systems, sub-meter global positioning systems (GPS), as well as vacuum and hydro-vacuum excavation methods to safely locate and identify buried utility infrastructure assets. Constantine’s team of SUE crews and engineers utilize a technologically advanced and knowledge-based approach to develop a realistic depiction and understanding of the underground utility infrastructure. These specialized services are then utilized to fully support the design and construction of new and maintenance-related projects of urban and rural sewer systems, to provide high quality evaluations of existing sanitary and storm sewer systems, to reduce constructability risk cost, and to assure the client’s existing infrastructure is protected.
