Civil construction support in Bunbury, Busselton and the South West.
You build it. We’ll prove every metre.
For civil contractors and land developers: we check quantities and services before you price, prepare variations and machine-control models while you build, and deliver the as-constructed records at handover.


A real drone survey measured against the issued design. Drag to see the cut and fill still to go.
Where we fit in your job.
Ten services, grouped by the stage your job is at. Bring us in for one, or for the whole run.
The pictures are real drone surveys with the issued design drawn over them: design strings cut to go fill to go
For developers: site and purchase review, town planning and subdivision coordination, pre-calc plans, tender, construction controls and handover. One team, one set of numbers.

PrimeCad is our own survey and design platform. It’s why we compare surfaces instead of marked-up PDFs, and why you get a record you can open instead of a file you have to chase.
- Surfaces, not drawingsExisting ground and design compared in 3D, with cut and fill measured across the whole surface.
- Every section on the sheetCross-sections and long sections cut from the model, not redrawn by hand.
- Your job in one placeQuantities, variations and revisions in a portal your team can open, instead of a thread of emails.

How we work.
Send what you have.
Drawings, models, site records, the tender package. We start from your files, at whatever stage the job is at.
We confirm scope, fee and turnaround.
Before any work starts you know what we will do, what it costs and when you will have it.
You get the checked result, with its workings.
Every figure comes with how we got it, so your team can check it and use it. Bring us in for one task or for ongoing support.

Questions.
What is civil construction support?
It is extra capacity for the project team on a civil job. We check quantities, measure drawing changes, prepare variation and progress records, build machine models, survey progress from the air and prepare as-constructed handover records, so your people can stay on the work.
Who is Project Prime for?
Civil contractors and land developers. Typically that means an estimator pricing a tender, a project manager chasing a variation or progress claim, or a developer working towards handover of a subdivision. If you are carrying the job and need another set of hands on the numbers, that is who we work for.
Where do you work?
We are based in Bunbury, Western Australia, and work across the South West: Bunbury, Busselton, Australind, Eaton, Capel, Dunsborough, Harvey, Collie and Margaret River. Much of the checking and preparation is done from the records you send, so the location of the job rarely limits what we can take on.
Can I engage you for one task, or do you only do ongoing work?
Either. Many clients start with a single task, such as a quantity check on one drawing set or a clash check on one design. Others agree ongoing support with defined capacity. We confirm the scope and fee before any work starts, and you decide whether to repeat it.
What software do you use?
We use PrimeCad, the survey and design platform we wrote ourselves, and a client project portal where results and records are shared. They are the tools we use on your job, not products we sell. We also work with the files and formats your team and designers already issue.
How do I get started?
Tell us about the job through the contact page or call (08) 9747 7377. Send what you have, such as drawings, a bill of quantities or a records list. We reply with the scope, fee and timing for you to approve, and work starts once those are agreed.
Send us the drawings.
Tell us what needs checking. We’ll confirm the scope, fee and turnaround before we start.
