3D GPR Survey Applications
3-D GPR surveys are useful throughout the lifetime of golf courses and athletic fields – for pre-design, construction, ongoing maintenance and operations, and renovation/rebuilding:
- Initial base mapping of a site subsurface - before golf course construction begins - to locate bed rock, utilities, underground drainage paths and other obstacles that can result in construction ‘surprises’ and cost overruns
- Establish a baseline of existing underground infrastructure and ‘as-built’ conditions where existing course records are incomplete or outdated
- Quality Assurance of the initial ‘as built’ course, greens, tees and critical drainage areas … and quality assurance for renovations and rebuilds
- View in great detail the location, flow and condition of underground drainage systems/pathways - before digging
- Mapping and assessment of greens and playing fields to determine subsurface characteristics in areas identified for remediation or renovation, including…
- Drainage systems (clean-outs, main line, branches and pipe junctions)
- Irrigation systems
- Soil/mix layer
- Drainage systems (clean-outs, main line, branches and pipe junctions)
- Locate subsurface areas with high water saturation compared to the surrounding vicinity
- Identify presence of voids and sinkholes and pinpoint their location in real time
- Pinpoint the location of leaks in irrigation systems and drainage pipes
- Maintain archival records of accurate, up-to-date ‘what is’ (vs. possible ‘as built’); note that survey data can be combined with GPS topography maps, if available.
Whatever the application, after the survey data is processed into 3-D images, you have a ‘mole’s eye view’ of everything below the turf. No other technology provides the level of detail and accuracy – all the benefits of digging … without a shovel.
