Subsurface utility investigation across the Eastern Suburbs, from Bondi and Randwick residential works to tight inner-city commercial and civil sites. No job too small. No project too large. From small contractors to major infrastructure.
The Eastern Suburbs sit on two grounds: the Botany sands aquifer that runs from Centennial Park through Randwick, Kensington and Maroubra to Botany Bay, and the sandstone headlands of Bondi, Bronte, Vaucluse and Watsons Bay. Sand gives ground penetrating radar its longest reach anywhere in Sydney, but the aquifer brings a water table that corrodes old services and makes trenching collapse-prone, so potholing by vacuum excavation is the safe way to prove a depth.
The CBD and South East light rail along Anzac Parade, the Randwick health and education precinct around Prince of Wales Hospital and UNSW, and the harbourside rebuilds in Rose Bay and Double Bay are the typical jobs. Ausgrid supplies the electricity, Sydney Water the water and sewer with its Bondi and Malabar ocean outfall systems, Jemena the gas and the Waverley, Randwick and Woollahra councils the stormwater.
The same accredited crew and AS 5488-2022 report across Eastern Suburbs 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.
LCG Architects, the group's residential design practice, works across the Eastern Suburbs on additions, dual occupancies and granny flats, and starts from the same locate and survey our crews deliver here, so the services are on the plans before the DA goes in.
Yes. The CBD and South East light rail corridor is Transport for NSW ground with its own access and permit rules, and our accredited crews work under them.
The sand holds a high water table and does not stand up when trenched, so open excavation near a service is risky. Vacuum excavation exposes the asset cleanly, and the hole is backfilled and compacted on the same visit.
Ausgrid for electricity, Sydney Water for water and sewer, Jemena for gas, Telstra and NBN Co for communications, and Waverley, Randwick or Woollahra council for stormwater, with the University of NSW and the hospital running their own private networks.
Yes. Concrete scanning before coring or cutting in apartment blocks, and non-invasive investigation of heritage structures, are regular jobs across the east.
