Price what is actually there
We quote from the drawings and a walk of the site. If there is limestone, a high water table or fill that has to leave, it is in the price before you sign it, not in a variation afterwards.
About
Coolderry Civil Pty Ltd is an Australian proprietary company working out of Perth's northern suburbs. We take on the earthworks, drainage and pavement scope that everything else on a site depends on.
Who we are
We are a Western Australian civil contractor. Our work sits at the front of the build programme — the clearing, the cut and fill, the pits and pipes, the road box and the pavement — and it is the part of a project that is hardest to fix once the next trade has covered it.
That shapes how we run a job. Levels are set out before machines start, drainage is proved before it is buried, and compaction is done to the specification rather than to the clock. It is unglamorous work, and doing it properly is the whole point.
We work directly for developers, head contractors, builders and local government project teams across the Perth metropolitan area, on scopes ranging from a single industrial pad to a staged subdivision road network.

How we work
None of this is complicated. It is just the difference between a civil package that closes out and one that comes back.
We quote from the drawings and a walk of the site. If there is limestone, a high water table or fill that has to leave, it is in the price before you sign it, not in a variation afterwards.
Layer thickness, compaction and pipe grades are done to the design and the relevant Australian Standards, and recorded as we go so the certifier is not guessing at handover.
Traffic management, exclusion zones, dust and sediment control are planned for the site rather than bolted on, and we obey the safety duties that apply to us under Western Australian work health and safety law.
You deal with the people running the job. When something on site changes, you hear about it that day and get an option, not a silence followed by a claim.
Who we work for
Most of our work comes through people who need a civil package delivered against a fixed programme.
Staged subdivision civil works, lot grading and road networks timed around titles and settlements.
Site cuts, sand pads, retaining and drainage delivered ahead of the slab and structural trades.
Hardstands, laydown yards, heavy-duty pavements, crossovers and truck access for operating sites.
Road upgrades, kerb and footpath renewal, drainage repairs and verge works in established suburbs.
The company
Coolderry Civil Pty Ltd is registered in Western Australia and holds the Australian Business Number and Australian Company Number shown here. Those details appear on every quote, invoice and page of this site so that anyone dealing with us can verify who they are contracting with.
