Tender Ready Without the Late Nights

Tendering construction projects takes time you might not have if you are a small to medium builder also managing current projects. The tender documents arrive, the deadline is in four weeks, and you need accurate quantities, up-to-date rates and a defensible tender sum before you can submit.

We provide tender estimating support for Perth residential and commercial builders and contractors. Document review, RFI support, subcontractor packaging, quantity takeoff, rate build-up and tender summary: the whole process, or just the components where you need extra capacity.

What We Do on Your Tender

01
Tender Document Review
We read the specification, drawings, contract conditions and any special conditions. We flag ambiguities, conflicts between documents and items that are unclear before we start estimating.
02
RFI Preparation
Where documents are unclear or conflicting, we draft Requests for Information (RFIs) for your submission to the principal. A good RFI saves re-pricing after a clarification lands at 5pm on day 25 of a 28-day tender.
03
Subcontractor Packaging
We identify which trades need to be sub-let and prepare scope documents for each package. This gets you comparable quotes from multiple subbies rather than one figure you cannot challenge.
04
Quantity Takeoff
All quantities measured from calibrated drawings for the trades you need estimated. Colour-coded markup and structured spreadsheet produced.
05
Rate Build-Up
Labour, material and plant rates built up from current Perth market rates. Significant items are cross-checked against at least two sources.
06
Tender Summary
Summary sheet with trade breakdown, prime costs, contingency and margin presented in the format required by the tender documents.

What Is Tender Estimating?

Tender estimating is the process of producing an accurate cost estimate for a construction project specifically in response to a tender invitation. Unlike a budget estimate, a tender estimate carries a real financial commitment, it is the basis of a contract if you win. Perth tender estimating should include document review, quantity takeoff from calibrated drawings, a rate build-up from current WA market rates, and subcontractor pricing of specialist trades.

Reading the Documents Before You Price Them

Most tenders are lost or won before a single rate is applied. They are decided in the two hours somebody spends reading the documents properly and finding what is not in them.

We go through the set first, mark the conflicts and the gaps, and give you the RFI list while there is still time to send it. A late RFI is just a note in your file, an early one changes the price.

What We Look for First

Architectural and structural drawings that do not agree
Specification clauses that contradict the drawings
Scope sitting in the preliminaries that nobody has priced
Exclusions in the invitation that shift risk onto you
Provisional sums that are really open ended items
Site access, staging and working hour restrictions
Missing finishes schedules or superseded standards
Programme dates that do not match the scope of works

The Tender You Should Not Bid

Not every tender is worth the four weeks it will take you. Some are wired for an incumbent, some carry risk no margin covers, and some are simply the wrong size for your crew.

We will tell you when we think that is what we are looking at. It costs us the fee and it saves you a month of unpaid work, which is the trade we would rather make.

When it is worth bidding, you get the numbers, the RFI list and the subcontractor packages, and you get them with enough runway to actually chase the quotes.

Common Perth Tender Challenges

Tight tender deadlines: 21-28 days for a project that needs four weeks of estimating work
Incomplete or conflicting documents: architectural and structural drawings that do not agree
Volatile material prices: concrete, steel and timber prices have moved significantly in WA
Subcontractor availability: subbies that are too busy to quote or quote very late
Specification gaps: specification sheets that reference an obsolete standard or leave the finish undefined
Scope creep in negotiations: verbal understandings from site visits not reflected in documents

Go or No-Go: Honest Advice Before You Start

Not every tender is worth submitting. Some jobs have risk profiles that do not suit your business. Some contracts have conditions that transfer unreasonable risk to the head contractor. Some clients have a track record that makes the tender not worth the time.

We will tell you straight if a job does not look like a good fit before you spend four weeks pricing it. That is part of the service.

Common Questions

Straight answers on how we price tender and bid estimating in Perth. If yours is not here, send your plans and just ask.

As soon as the documents arrive, if possible. We need time to review documents, raise RFIs and wait for responses before pricing starts. Engaging us in the first week of a four-week tender gives us the best chance of producing an accurate number in time.

Yes. If you are a subcontractor responding to a head contractor's tender request, we can estimate your scope and produce a priced schedule you can submit directly.

We provide the estimating data in the format required. For government tenders with specific submission portals and complex compliance requirements, we recommend engaging a quantity surveyor for the final submission compliance check.

Addenda and clarification drawings are incorporated when they are received. If the change is significant, we advise on the impact before incorporating it so you can decide whether to continue with the revised scope.
