VA Dorn Columbia Sewer Line Replacement
CES Group Engineers provided Subsurface Utility Engineering (SUE) services for the design of a new sewer system at the VA Dorn Medical Center.
01 Project Scope:
The scope included Level B utility designating using electromagnetic locating, ground-penetrating radar, and inductive sweeps, along with Level A test hole excavations using vacuum trucks to expose and confirm utility locations. CES also conducted closed-circuit television (CCTV) inspections to assess pipe conditions and tie-in points. These efforts delivered accurate utility data for the design team, reducing risk and enabling conflict-free planning.
02 The Challenge:
The VA Dorn Medical Center’s mature facility infrastructure and active operations created a uniquely complex underground environment that required precision and adaptability. CES encountered a range of conductive and non-conductive utilities, prompting the use of multiple advanced locating methods to ensure accuracy. Work within the busy medical campus demanded thoughtful coordination and scheduling, with restricted access in certain areas to maintain safety and support uninterrupted care. These conditions underscored the importance of delivering dependable, high-confidence utility data to support the design team’s goals and meet strict federal standards.
03 The Result:
CES executed a multi-phased utility investigation strategy that combined advanced geophysical tools, precision test holes, and real-time field coordination. By delivering detailed and verifiable utility data, CES enabled the design team to avoid conflicts and streamline construction planning. The firm’s responsive approach, technical accuracy, and ability to operate within sensitive environments ensured minimal disruption and supported critical infrastructure upgrades for the VA.
