Subsurface utility investigation across The Hills, Castle Hill, Baulkham Hills and Norwest, supporting metro-linked commercial and residential development. No job too small. No project too large. From small contractors to major infrastructure.
The Hills District changed shape when Sydney Metro Northwest opened, and the stations at Castle Hill, Norwest, Bella Vista, Kellyville, Rouse Hill and Tallawong are now the centre of high-density precincts replacing acreage and single-storey commercial. The Norwest business park has a dense private network of fibre and chilled water alongside the public services, and the Rouse Hill and North Kellyville release areas are still laying trunk mains.
The ground moves from Cumberland Plain clay in the west to Hawkesbury sandstone and shale on the ridges around Dural, Glenhaven and Castle Hill, so the locate method changes within a single job. Endeavour Energy supplies the electricity, Sydney Water the water and sewer, including large trunk mains through the growth centres, and Transport for NSW the Metro corridor and Windsor Road.
The same accredited crew and AS 5488-2022 report across The Hills District 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.
Yes. The station precincts at Castle Hill, Norwest, Bella Vista, Kellyville, Rouse Hill and Tallawong are busy development sites, and our locators and surveyors hold the Transport for NSW accreditation for work near the corridor.
Clay on the plain around Rouse Hill and Kellyville, moving to shale and sandstone around Castle Hill, Dural and Glenhaven. Radar reads well on the sandstone and poorly on the clay, so we plan the method street by street.
Endeavour Energy for electricity and Sydney Water for water and sewer, with Jemena gas in the established suburbs and The Hills Shire Council stormwater.
Yes. Rural lots around Dural, Kenthurst and Annangrove often have private water, septic and power runs with no plans at all, and a locate before building or fencing is the only reliable way to find them.
