- Detailed investigation of any available records, plans, and maps
- Thorough electronic search of the site for buried facilities
- Accurate mapping of all locatable subsurface utilities utilizing the latest in surveying technology combined with utility records research, resulting in precise horizontal and vertical coordinates of all structures
- Coordinates can be plotted and provided in ASCII, AutoCAD DWG, and MicroStation format
Subsurface Utility Locating
Excavating test holes to determine the exact horizontal and vertical location of existing utilities, a critical step to final design and early construction phases.
Advantages & Services Include:
- Test holes determine the exact horizontal and vertical location of existing utilities
- Non-destructive, vacuum excavation exposes the utility at all points of possible conflict
- Field staking of the exact location of the proposed features and possible utility conflicts
- Restoration of the test hole and marking of the location, utilizing established utility designating color codes and ASCE Standards of Practice
- Formal Test Hole Report and Inventory for all structures found
- Total station survey of test hole locations for CADD mapping
Ground Penetrating Radar (GPR)
Ground Penetrating Radar (GPR) involves the non-destructive location of subsurface targets prior to digging, trenching, or conducting site assessments.
Accumark offers full color CCTV inspection services for sewer/drain line pipes and empty electrical/telecommunication conduits as small as 2″. The system provides recorded color video data, and can electronically designate the horizontal location of the CCTV camera head by means of a built in Sonde.
