Woods is a market leader when it comes to its underground surface locating (USL). We can locate and map underground infrastructure assets and services at scale anywhere in New Zealand.
This reduces risk, improves site safety, and helps you avoid costly surprises. At Woods, we use a combination of service plans, Electromagnetic Induction (EMI) tools, Ground Penetrating Radar (GPR), manhole lifters, and visual inspections to identify underground hazards and assets.
We can provide detailed and high-precision mapping in confined spaces, including manhole chambers, culverts, stormwater pipes and other underground cavities.
We are also able to locate subterranean utilities, assets, and hazards prior to excavation. This helps ensure the avoidance of costly mistakes before work commences.
We have market leading solutions, including:
3D Ground Penetrating Radar (3D-GPR) – vehicle towed
2D Ground Penetrating Radar (2D-GPR)
Electromagnetic Induction (EMI)
SLAM handheld / portable laser scanning
Towed 3D-GPR capture is ideal for projects involving large road corridor extents, as it enables data capture to be undertaken with no, or minimal, traffic management support, thereby saving significant time and costs.
For projects, where there is a mix of carriageway, footpath and berm USL required, Woods is able to prioritise carriageway capture, followed by more targeted berm and footpath capture activities. This enables clients to gain insights into the largest extent of the project area in the shortest timeframe and at the lowest per unit cost.
Woods will give you confidence in what’s below ground — so you can plan and build safely above it.
