Underground Utility Locates
Bateman Civil Survey Company has been responsible for locating and marking the underground utilities owned by the Directorate of Public Works at Ft. Stewart and Hunter Army Air Field since 10/01/2009. We receive our notification through the Georgia PUPS system, and are very familiar with this type of system and its’ requirements and expectations. Each project required the location of 4 types of utilities – water, gas, sewer and secondary electrical. The piping material for these utilities includes cast iron, steel, plastic and vitreous nonmetallic pipe. We have used electromagnetic equipment from Metrotech, Pipehorn, Subsite, and Radio Detection, as well as MALA Ground Penetrating Radar.

BCSC Dospiva has performed topographic, hydrographic, geophysical and underwater engineering inspection surveys for the LPG conversion of the Virgin Islands Water and Power Authority plants on St. Thomas and St. Croix for Vitol based in The Netherlands. BCSC has performed boundary and topographic surveys, utility locations, and water resource management for both projects including, soil erosion and sedimentation control plans, grading design, Stormwater Pollution Prevention Plans and assistance with local permitting. We have performed offshore surveys using an echosounder, sub bottom profiler, magnetometer, and sidescan sonar, for the areas around the fueling docks at both plants, as well as for a mooring location 5 miles offshore. We performed underwater engineering inspections of docks at both plants, including steel thickness measurements, videography and sample collection. We have also performed structure and roadway inspections pre-construction, to document existing conditions using videos and still frame photography.

BCSC Dospiva conducted a magnetometer survey, sidescan sonar, sub-bottom profiling and a single beam echosounder of the area for a proposed offshore windfarm. We provided these offshore survey services and delivered a report of survey for this project depicting underwater objects located by the survey, based on standards as set forth by the Bureau of Ocean Energy Management for Submission of Spatial Data for Site Characterization Surveys. We have also conducted boundary and topographic surveys on shore for the proposed beach manhole and landing site, as well as nearshore surveys in the shallow water depths. We have drawn up easement documents for the onshore route of the proposed electric line, and are currently waiting on regulatory agency review prior to beginning the preparation of construction documents.
