About Prime Estimation

Estimators Who Understand Building Costs

Better standards. Sharper estimates. A price you can trust.

We prepare construction estimates for anyone who needs a price for a tender: head contractors, subcontractors, developers and builders. Send us your drawings and we return itemised estimates and quantity takeoffs priced for your area, normally in one to two days.

We work for clients across Australia from our office in Gosnells, Western Australia. So far we have priced over 1,500 government, institutional, commercial and residential projects.

Why We Exist

Rushed Numbers Cost Good Builders Their Profit

For most builders, money is lost in the estimate and not in the building. A late-night takeoff done to meet a deadline, a national average used instead of a local price, or an exclusion nobody recorded can each cost you the job or the profit.

We started Prime Estimation to solve this. Builders can use us as their own estimating department when they need one, with experienced estimators, professional takeoff software and current cost data, and without paying for salaries, licences or overheads.

  • Measured, not guessed. Quantities are taken directly from your drawings and sorted into ASMM / ANZSMM trade sections.
  • Priced where you build. Material and labour prices are set for the project postcode each time.
  • Written down. Every estimate includes a page of assumptions and exclusions, which helps you explain your price when the scope is reviewed.
How We Work

How We Work on Every Estimate

These rules apply to every job, large or small.

A second set of eyes

Another estimator goes through each estimate, looking at the quantities, formulas and totals. When their numbers differ noticeably from the first, we recheck the whole thing.

Honest about accuracy

We tell you the accuracy range that matches your design stage, instead of promising a precision that your drawings cannot support.

Fixed fee, agreed first

Before we start, you know the price and the delivery date. There are no hourly charges, and the final invoice never goes above the quote.

Your format, not ours

You receive Excel and PDF files as standard, or we can fill in your own tender template so it fits straight into the way you work.

Confidential by default

We keep your drawings, prices and client details private, and we will sign an NDA before you send anything if you ask us to.

Straight answers on time

If we cannot make your deadline, we say so straight away rather than accept the work and deliver it late.

Our Team

Who Will Work on Your Estimate

Each project moves through people with their own set tasks, so the work does not depend on one person spotting every error.

Scope review

Starts by reading your plans and specifications, notes gaps and conflicts, and then gives you a set fee and delivery date.

Trade estimators

Estimators with site experience who measure and price their own specialist trades, such as concrete, building services and finishes.

Reviewing estimator

A different estimator who checks all quantities, formulas and totals before you get anything.

Your account estimator

Returning clients keep the same estimator, who gets to know your tender format, margins and preferences.

What We Bring

A Full Estimating Team Without the Extra Cost

Our measuring is done in PlanSwift, Bluebeam Revu and On-Screen Takeoff. Prices are based on Rawlinsons-style Australian cost guides, Australian supplier prices and our own regional data, updated against current supplier pricing.

You do not need to buy software, update cost data or pay an estimator during slow months. You pay for each project, and only when you have a tender to prepare.

Every sector

Government, institutional, commercial, industrial and housing work.

Full ASMM / ANZSMM

Every ASMM / ANZSMM trade section and NPWC / AIQS element.

State levies and awards

Award rates and state levies, such as long service leave, carried as separate lines.

Any file type

PDFs, DWG/CAD files, BIM models and clear scans of paper plans are all accepted.
