Built on precision.
Trusted by the best.
SNZ Plumbing Estimating exists for one reason — to give plumbing contractors, developers and government agencies hydraulic estimates they can actually build a winning tender around. Not approximate. Not templated. Precise, verified and bankable. See the projects that prove it →

"Every estimate we produce has my name on it. That means it has to be right — not approximately right. Right."
Why SNZ exists —
and why it matters.
SNZ was founded on a simple observation: most plumbing estimates in Australia are produced by generalists — quantity surveyors or estimators who cover every trade. See the difference on a 25-storey residential tower where a single missed item costs hundreds of thousands. They have templates. They have averages. What they don't have is the deep hydraulic expertise to know when those averages are wrong — and they often are.
Shoaib Saeed founded SNZ to change that. With a civil engineering degree, 15+ years of hands-on construction and estimating experience across Australia, the Middle East and South Asia, SNZ was built to do one thing exceptionally well.
Today SNZ serves Tier 1 contractors, government agencies, major developers, architects and hydraulic engineers across seven states and territories and territories. Every estimate is produced from your actual drawings — not industry averages — and every number is independently verified before it leaves our office.
The result is an estimate you can actually bid on. Precise. Bankable. Trusted.
Shoaib graduates with a Bachelor of Civil Engineering and begins building hands-on experience across construction projects in Australia and internationally.
Years of project experience across the Middle East and South Asia — large scale infrastructure, commercial and residential hydraulic scopes — builds technical knowledge rare in Australian estimating.
SNZ Plumbing Estimating is established in Sydney with a single focus — hydraulic estimating done at the highest possible level. Sydney, Melbourne and Brisbane offices follow. See every project we have delivered.
SNZ has completed 300+ hydraulic estimates across every sector — including secure government and defence facilities where full project details are withheld at the client's request — high-rise residential, hospitals, government infrastructure, national retail and universities. 65+ five-star Google reviews and counting.
Three things we will
never compromise on.
These aren't marketing words. They're the standard every SNZ estimate is held to.
Every estimate is produced from your actual drawings using PlanSwift — not industry averages, not templated assumptions. Every line item is individually measured and priced. A second estimator reviews every estimate before it leaves our office. See the results →
When we commit to a turnaround time, we deliver on it. 72 hours for small to medium projects. Timeline confirmed upfront for large and complex scopes. We remain available throughout your entire bid.
65+ five-star Google reviews from real contractors who trusted us with their tenders. We price honestly, communicate clearly and never overpromise. When we say the numbers are right, they are right.

Shoaib Saeed —
Civil engineer. Estimating specialist.
Shoaib Saeed founded SNZ Plumbing Estimating after 15+ years in civil engineering and construction across Australia, the Middle East and South Asia. That breadth of international experience gives SNZ a perspective on hydraulic estimating that is simply not available from firms that have only ever worked in one market.
As a civil engineer by training, Shoaib understands how hydraulic systems interact with structural, civil and site constraints in ways that a pure estimator cannot. That technical depth shows in every estimate SNZ produces — in the line items that less experienced estimators miss, in the allowances that others underestimate, and in the overall accuracy that SNZ clients rely on.
"The reason clients keep coming back is simple — our numbers hold up on site. That's not something you can fake. It comes from doing the work properly, every single time."
