From a knock-down rebuild to a new estate pad, each service has its own page with the detail.
Macquarie Park sits about 16 kilometres north-west of the city. You'll recognise it by Macquarie University, Macquarie Centre, Macquarie Park metro and Lane Cove River. It's ringed by North Ryde, Marsfield, East Ryde, Eastwood and Epping. What's changing: high-rise apartments and commercial towers around the metro.
Macquarie Park's housing near Macquarie University runs to office towers, the university and high-rise apartment precincts around the metro stations. Near Macquarie University, duplex and unit sites cluster near the centres. In Macquarie Park that's basement digs, site cuts and drainage and service trenches more often than not.
Macquarie Park sits on Shale over sandstone with deep fill in the business and university precincts, out toward Macquarie University. Toward Macquarie Centre the sandstone starts early, so Macquarie Park digs are planned around rock from day one and sawn on the lines. Around Marsfield, the clay is reactive, so fill goes in in compacted layers.
Macquarie Park is in City of Ryde, and around Macquarie University there's no flood or bushfire overlay, so it's a standard DA or CDC job. Machines come in to Macquarie Park off Epping Road or Lane Cove Road, and it's tight to get a truck down the inner streets.
Every job follows the same sequence, whether it's a single trench or a full site cut.
A trench can be a day, a basement can be weeks. Dates come with the quote, not after.

See the whole Ryde and Hornsby area →It depends on the volume of material, the ground (shale over sandstone with deep fill in the business and university precincts), access for the machine and how far spoil has to be carted. Every job gets a written quote after a site look, with the dig, cartage and cleanup spelled out, so you know what’s included before anything starts.
Usually, if the excavation is part of a build. Cut and fill beyond set limits, work near boundaries and anything on a lot with a flood, bushfire or heritage overlay needs approval as part of the DA or CDC. We work to the approved plans; check with your certifier before the dig is booked.
A trench, pool dig or single pad is a day or two; a knock-down site cut or a basement runs longer and depends on volume, ground and weather. Dates come with the quote, not after.
Yes. Shale over sandstone with deep fill in the business and university precincts. On the river slopes, in the gullies and across the Hornsby plateau, sandstone is usually within the first metre. It’s sawn at the boundaries and broken out, and it’s in the quote when the site look finds it.
That’s the most common ground in this region and it’s priced as two jobs: clay cut and compacted fill on the ridge side, saw and breaker where the block drops into rock. The site look finds where the change is so it’s in the quote from the start.
Yes. Basements in Macquarie Park go through shale into sandstone, are sawn at the boundaries and dug in stages to the shoring engineer’s sequence, with creek groundwater planned for from the geotech. Spoil is trucked on a schedule so the street stays clear.
Reactive clay. It swells in wet winters and shrinks in dry summers, and anything poured on loose or uncompacted fill moves with it. A pad cut and filled in compacted layers to the engineer’s spec is what stops the new slab doing the same thing.
Yes. One house down, the block stripped, and two pads cut and compacted to the engineer’s spec, with the basement dug if the design has one.
