SUI, GPR concrete scanning and service mapping across Chatswood, North Sydney and the Lower North Shore, supporting commercial fit-outs, basements and high-density sites. No job too small. No project too large. From small contractors to major infrastructure.
The Lower North Shore packs commercial towers, hospital precincts and apartment blocks onto sandstone ridges around Chatswood, St Leonards, Crows Nest and North Sydney. The Sydney Metro stations at Crows Nest and Victoria Cross have reshaped the streets above them, the Royal North Shore Hospital precinct carries one of the densest private service networks in Sydney, and the Pacific Highway corridor stacks Ausgrid feeders, Sydney Water mains, Jemena gas and carrier fibre in a narrow verge.
Sandstone is good news for radar and bad news for anyone who laid a pipe: services here often run shallow, follow rock rather than the plan, and were relocated during the Warringah Freeway and Western Harbour Tunnel works. A large share of our Lower North Shore work is concrete scanning in commercial fit-outs and basement car parks, alongside locates for the residential rebuilds in Willoughby, Lane Cove and Mosman.
The same accredited crew and AS 5488-2022 report across Lower North Shore 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 North Shore 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. Post-tension cable and conduit scanning before coring in office towers, hospital buildings and apartment car parks is daily work on the Lower North Shore, with no radiation and no shutdown.
Yes. Our crews hold the Transport for NSW accreditation and Rail Industry Worker cards needed near the Metro corridor, and we work under the permit conditions around the freeway and tunnel sites.
Ausgrid for electricity, Sydney Water for water and sewer, Jemena for gas, with Willoughby, North Sydney, Lane Cove and Mosman councils owning the stormwater and Transport for NSW the highway and rail corridors.
Our Lindfield office is a few kilometres up the Pacific Highway from Chatswood, so Lower North Shore sites are among the quickest for us to reach.
Send us the site and program. We come back with a same-day quote and deliverables to suit.
