Working in Newcastle & Hunter

What the ground is like, and who owns what.

Newcastle sits on a coalfield. Much of the inner city and the suburbs towards Lake Macquarie are undermined by workings from the 1800s onward, the port and Honeysuckle precincts are reclaimed land over fill, and the city centre was rebuilt around the Newcastle light rail and the Hunter Street renewal. Voids, old mine shafts and the subsidence district rules change how a site can be founded, and the subsurface investigation has to find them before the geotechnical drilling is targeted.

The asset owners are different from Sydney: Ausgrid for electricity, Hunter Water for water and sewer, Jemena for gas, and Newcastle, Lake Macquarie, Maitland, Cessnock and Port Stephens councils for stormwater. The Hunter Expressway, the Newcastle Inner City Bypass and the Main North and coal rail lines are Transport for NSW and ARTC corridors. We cover the Hunter Valley to Singleton and Muswellbrook and Port Stephens to Nelson Bay from the same crew.

FAQ

Utility locating in Newcastle & Hunter: common questions.

Who supplies water and sewer in Newcastle?

Hunter Water, not Sydney Water. Its plans, drafting standard and access rules differ, and our utility surveys are delivered to its requirements across Newcastle, Lake Macquarie, Maitland, Cessnock and Port Stephens.

Can you find old mine workings and voids?

Ground penetrating radar and other geophysical methods map shallow voids, shafts and disturbed ground in the top few metres, which targets the deeper geotechnical investigation the Subsidence Advisory NSW process requires. Deep workings need drilling, and we say where.

Do you work in the Newcastle port and Honeysuckle precincts?

Yes. Reclaimed land there carries buried rail, old wharf structures and abandoned pipelines under the fill, and a subsurface investigation before design or piling is standard practice.

How far up the Hunter Valley do you travel?

Maitland, Cessnock, Singleton, Muswellbrook and the vineyards are regular work, as are Port Stephens and the Lake Macquarie suburbs, with same-week scheduling for most jobs.
