Best Rating in your town in estimating business
Winning a tender comes down to a price that’s low enough to get the job and high enough to make money on it. That only works if nothing gets missed. Our construction estimating services cover the main types of work builders and contractors bid on across Australia, from a single house to a large industrial build. Send us the plans and specs, tell us your closing date and we’ll price the job trade by trade. Your tender estimate comes back in 24 to 48 hours as an Excel or PDF file you can use straight in your submission.
Our residential estimating services cover new homes, townhouses, units, renovations and extensions. We measure every trade from your plans, price the materials and labour, and show allowances for anything the drawings leave open. You get a tender estimate that works whether you’re quoting a homeowner, bidding for a developer or pricing a job for another builder. A small renovation or a block of units, the numbers are laid out the same way, so they’re easy to check.
Our commercial estimating services cover offices, shops, schools, medical centres, hotels and fit-outs. Commercial jobs have a lot of trades and a lot of documents, so we break the tender estimation down trade by trade and flag anything that doesn’t match between the drawings and the specs. That makes it easier to compare against your sub quotes and catch gaps before the tender goes in.
Not every job needs a full tender. Our public bid estimating services help you price council, state and government bids, where the paperwork is strict and the deadline doesn’t move. We go through the documents, price the work and update the numbers when an addendum comes out, so you’re never pricing an old set. If you want a rough figure first, we also prepare a pre-tender estimate before the documents are finished.
Our industrial estimating services cover warehouses, factories, sheds, distribution centres and plant buildings. These jobs are heavy on slabs, steel and cladding, so we measure those items carefully and price the services around them. Our tender cost estimation lists the big cost items separately, so you can see what moves your price the most and where to sharpen it before you submit.
We provide construction estimating and material takeoff services for professionals across Australia’s construction industry.
Send us your project drawings, plans and specifications for review. We’ll assess the scope of work and the information provided to understand your tender estimating requirements.
We review your project requirements and provide a quotation based on the scope of work. You’ll know the proposed cost and service details before proceeding with your estimate.
Once you’re happy with the quotation, confirm the order so we can proceed. We’ll use the agreed scope and supplied documents to begin preparing your material takeoff.
Receive your completed material takeoff with quantities organised for easy review and tender preparation. The takeoff helps you assess material requirements and use the quantities when pricing your construction project.
Tender deadlines don’t move, so we don’t take long. Send us the plans and specs, and your tender estimate comes back within 24 to 48 hours, ready to use in your submission.
You get a clear breakdown of every trade, not one big number. That makes it easy to check against your sub quotes, spot gaps and change an allowance before you submit.
We price using current local material costs and labour rates, and we work to Australian plans and terms. The numbers fit the way jobs are actually bid and built here.
Your estimate arrives as an Excel or PDF file, laid out trade by trade. Copy it into your tender, send it to your client or hand it to your team without reformatting anything.



Price too low and you win the work, then pay for the gap yourself by the time the job is handed over.
Pad the price by mistake and you’re out of the running before the client looks at your quality.
Supervision, scaffold, waste removal and travel are easy to forget and hard to recover once the job starts.
When inclusions and exclusions aren’t clear, the client assumes extras are covered and you end up arguing over who pays.
Packages sent out on a poor scope come back with gaps between trades or two subs pricing the same work.
Surprise costs arrive mid-job, when your money is already tied up in labour and materials.

of Experience
We work out what a job will cost so you can put a price on your tender. You send the plans and specs, and we measure the work, price each trade and give you a clear estimate to use in your submission. It saves you the hours it takes to do it yourself when a closing date is close.
The difference between tendering and estimating comes down to this: estimating is working out what a job will cost, and tendering is submitting that price to win the work. Estimating and tendering for construction work go together, because a tender is only as good as the estimate behind it.
Our tender cost estimation covers quantities, materials, labour and allowances, set out trade by trade. We also list what’s included and excluded, so you can see where the price comes from and change anything you want before you submit.
It’s an early price, worked out before the full documents are ready. Builders use it to check a job is worth chasing or to give a client a budget figure. Once the final drawings and specs arrive, we can turn it into a full tender estimate.
Send the plans and specs, any addenda and your closing date. If the job has a bill of quantities, send that too. Not sure what’s needed? Send what you have, and we’ll tell you if anything is missing.
