Whatever you are tendering, we have priced it before.
Four steps. Zero surprises.
Send us your drawings
PDF, DWG or Revit. We review everything before work begins and ask the right questions upfront. Nothing is assumed.
Detailed takeoff and pricing
Every pipe, fitting, fixture and labour item individually measured and priced in PlanSwift, from your specific drawings. Nothing averaged, no industry templates.
not estimated
Independent review
Every estimate is checked by a second estimator before it leaves our office. This is the step most estimating firms skip. We never do.
before it ships
Delivery in your format
Excel BOQ, PDF summary or a tender-ready breakdown, set out the way your submission requires. If you need to know how we arrived at any number, we will walk you through it.
not ours
Four things you will not get anywhere else.
Rates that move the day the market moves.
Most estimates run on rate books that update once a year. When conflict in the Middle East recently pushed material prices up sharply, the next estimate out of our office carried the revised rates the same day, not at the next quarterly update.
Why this matters →Illustrates a past market movement and how quickly we applied it. Not a live price feed.
Plumbing and hydraulics. Nothing else.
We are not a generalist firm that also prices plumbing. Every hour of our week is hydraulic scope, which is why we read it faster and price it more accurately than a firm splitting attention across twenty trades.
About the firm →Sit across the table from your estimator.
We are in Bankstown, Sydney. Bring your drawings and your printed estimate, have a coffee, and we will walk you through every line and where each dollar came from.
Come and see us →An AI estimate looks finished. That is what makes it dangerous.
On a recent high-rise in Southport, an AI hydraulic estimate came in around 40% below ours for the same drawings. A tool prices what is drawn and treats a simple job and a complex one the same way.
Why an AI estimate is a risk →Projects that prove the standard.
5.0 from 69 reviews. Real contractors, real tenders.
Worth every penny. SNZ estimated a large commercial hydraulic, civil and fire package in SA on a tight timeline. Their detailed estimate provided everything we needed to fill in the tender documents with ease.
The accuracy and detail were second to none. Everything was broken down and very clear to see pricing for each part of the job. Would certainly not hesitate to recommend SNZ.
Upfront pricing, great communication throughout, and the end result was a well mapped, high detail estimate. Will use again. Makes our admin time a lot more streamlined.
