Utility locating and non-destructive excavation across Hornsby and the Upper North Shore, from established residential streets to bushland-edge civil works. No job too small. No project too large. From small contractors to major infrastructure.
Hornsby and the Upper North Shore are our home ground: the LCG office is in Lindfield, a few stations down the North Shore line. The area is Hawkesbury sandstone with thin sandy soils, which is the best ground in Sydney for ground penetrating radar and the worst for trenching, so most services were laid shallow and many were moved around rock without the record being updated. Established streets from Wahroonga to Pymble carry century-old water and sewer lines beside new fibre.
Ausgrid supplies the electricity, Sydney Water the water and sewer, Jemena the gas and Hornsby Shire and Ku-ring-gai councils the stormwater, with the Pacific Highway and the North Shore rail line under Transport for NSW. The Hornsby Town Centre renewal, the hospital precinct and the steady run of knock-down rebuilds and second-storey additions on large blocks are the typical jobs, along with bushland-edge civil works where the sandstone comes to the surface.
The same accredited crew and AS 5488-2022 report across Hornsby & Upper 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 Northern Sydney 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.
Our office is in Lindfield, on the Pacific Highway between Hornsby and Chatswood, so Upper North Shore sites are usually a short mobilisation and can often be fitted in at short notice.
Yes. The sandstone and sandy soils are ideal for ground penetrating radar, which reads deep and clear here, so plastic pipes, conduits and old stormwater lines that EM cannot trace are usually found.
Ausgrid for electricity, Sydney Water for water and sewer, Jemena for gas, Telstra and NBN Co for communications and Hornsby Shire or Ku-ring-gai council for stormwater, with Transport for NSW assets along the Pacific Highway and the rail corridor.
Yes. A locate before a second storey, a pool or a granny flat on a North Shore block finds the sewer, stormwater and power lead-in that decide where the work can go, and LCG Architects can take the result into the design.
Send us the site and program. We come back with a same-day quote and deliverables to suit.
