Our home market is NSW — we know Sydney construction costs, Sydney subcontractor rates, Sydney council requirements and Sydney building code applications better than any interstate firm.

From a 25-storey residential tower in Western Sydney to a NSW Health hospital redevelopment in regional NSW — SNZ has estimated hydraulic packages at every scale, across every sector, in every corner of the state.

300+ projects estimated. 65+ five-star Google reviews. A perfect 5.0 rating. The numbers speak for themselves — but the real proof is in the projects we have delivered.

Why NSW contractors
choose SNZ.

Sydney and NSW contractors choose SNZ because we are local, we are specialist and we have a proven track record at every scale — from a boutique apartment development in the inner west to a 25-storey landmark tower in Western Sydney to a government hospital in regional NSW.

We know NSW construction. We know the rates, the supply chains, the council requirements and the compliance obligations that apply specifically in this state. That local knowledge is built into every estimate we produce.

Founded by civil engineer Shoaib Saeed with 15+ years of hands-on experience — SNZ brings a depth of technical knowledge that no generalist estimating firm can match.

Gran Central at Granville — 373 apartments, 25 storeys, 5-level basement — is one of our lead projects. Western Sydney construction is our home ground.
