Utility locating, concrete scanning and non-destructive excavation across the Sydney CBD, from tower basements and podiums to congested inner-city service corridors. No job too small. No project too large. From small contractors to major infrastructure.
The Sydney CBD footpath is the most congested ground in the country. Under a typical city verge sit Ausgrid high-voltage feeders and the CBD cable tunnels, Sydney Water trunk mains and brick oviform sewers from the 1800s, Jemena gas, the chilled water and district energy loops that serve the towers, Telstra and Optus duct banks, and the private fibre every carrier has pulled in over thirty years. Plans are layered rather than complete, and many pits are shared.
Access is the second constraint. Night works under City of Sydney and Transport for NSW permits, pedestrian management on George and Pitt streets, the light rail corridor through the centre of the city and the Sydney Metro stations at Martin Place, Barangaroo and Gadigal all bring their own conditions. We scan basements, podiums and car park slabs for tower fit-outs by day and locate in the street by night, with traffic control arranged as part of the job.
The same accredited crew and AS 5488-2022 report across Sydney CBD 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.
Depth and density. Services sit in stacked layers, metal lids and tram rails distort electromagnetic signals, and radar sees a crowd of reflections. We work in short sections, trace each service from its own pit and pothole where a design or an excavation needs certainty.
Yes. Our locators and surveyors hold the Transport for NSW accreditations and Rail Industry Worker cards for corridor work, and we manage the permits for the light rail alignment and the Metro station precincts.
Yes. Concrete scanning for post-tension cables, conduits and reinforcement in commercial towers is a large part of our CBD work, with no radiation and no exclusion zone, so the fit-out keeps running.
Yes. Most street work in the CBD runs at night under permit, and we provide crews, traffic control and 24/7 emergency call-outs.
