Subsurface utility investigation across Wollongong, Shellharbour and the Illawarra. No job too small. No project too large. From small contractors to major infrastructure.
The Illawarra is a narrow coastal plain between the escarpment and the sea, with Wollongong, Port Kembla and the steelworks at its centre and Shellharbour, Kiama and the Southern Highlands around it. The industrial land around Port Kembla carries a century of private pipelines, rail sidings and tanks under fill, the University of Wollongong and the hospital run large private networks, and the coastal suburbs sit on sand over rock with a high water table.
Endeavour Energy supplies the electricity, Sydney Water the water and sewer across the Illawarra, Jemena the gas, and Wollongong, Shellharbour and Kiama councils the stormwater. Mount Ousley Road and the M1 Princes Motorway, the Albion Park Rail bypass and the South Coast rail line are Transport for NSW corridors, and the Mount Ousley interchange and the Shell Cove and Calderwood release areas are the current major works.
The same accredited crew and AS 5488-2022 report across Wollongong & Illawarra and NSW, whether it's a single locate or a tier-one program.
Detection, tracing and marking of underground services using electromagnetic and ground-penetrating radar, to the accuracy each site demands.
Engineering-grade utility survey and drafting to AS 5488-2022, delivering 12D/DWG models, BIM-ready 3D strings and GDA2020 deliverables.
Safe vacuum potholing to positively identify services and achieve the highest Quality Level (QL-A), without damaging the asset.
GPR concrete imaging before cutting, coring or drilling. Locates rebar, post-tension cables, conduits and voids. Radiation-free, no site shutdown.
Push-rod and crawler camera inspection, connectivity mapping and condition reporting for pipes up to 2 m in diameter.
USTs, concrete substructures, voids and rock seams, plus unmarked-grave, forensic and archaeological investigations.
Endeavour Energy for electricity, Sydney Water for water and sewer, Jemena for gas, Telstra and NBN Co for communications and Wollongong, Shellharbour or Kiama council for stormwater, with Transport for NSW owning the motorway and rail corridor assets.
Yes. Buried pipelines, old rail, tanks and foundations under the fill are mapped with radar, EM and survey and reported to AS 5488-2022 with coordinates for the environmental and demolition teams.
Yes. Both are Transport for NSW ground, and our accredited locators and surveyors work under the corridor and traffic control conditions, including night shifts.
Wollongong, Shellharbour, Kiama, the Southern Highlands and down to Nowra and the Shoalhaven are regular work, scheduled with the client for multi-site programs.
