JMT has provided subsurface utility locating and designating services for more than ten years in association with our survey services.  We recently enhanced our capabilities with a new VacMasters System 4000 truck, which permits us to complete all aspects of test hole excavations, including records research, air-vacuum test pits, utility designating and identification, and verification of underground utilities.  This forced air vacuum excavation system is minimally invasive and quickly provides detailed information vital to the design of projects.
