BIM Estimating
Quantities pulled from IFC and Revit models, checked against the drawings and then priced
A model carries quantities, but only as good as the modelling. Walls modelled as single elements, missing finishes and untagged items all need an estimator to interpret.
We take the quantities out of the model, compare them with the 2D drawings, measure by hand anything missing and send back a priced estimate along with a list of problems found in the model.

How We Prepare Your Estimate
Five steps from your drawings to a BIM number you can defend in a scope review.
-
01
Scope review
An estimator reads the architectural and engineering drawings and specification before touching a takeoff tool, and lists every assumption, exclusion and missing item as a query for you to confirm. Nothing is priced on a guess.
-
02
Digital measurement
Quantities are measured digitally in Bluebeam Revu, PlanSwift or On-Screen Takeoff, in metric: metric quantities. Each measurement sits on a named layer, so the marked-up PDF you receive is a visual audit trail.
-
03
Pricing
We price the quantities using current Australian supplier quotes, subcontract rates and published benchmarks such as Rawlinsons, adjusted for your postcode and state. If you give us your own rates or a preferred supplier schedule, we use those.
-
04
Senior QA review
Before anything is sent, a second estimator compares the takeoff with the drawings and verifies the measuring rules, deductions, wastage allowances and productivity assumptions.
-
05
Delivery
Excel and PDF files reach your inbox within one to two days for standard jobs. One round of changes is included, and we remain available for tender queries and scope questions after the tender.
Tooling
Software We Work In
You do not have to hold a licence for these tools. We do the measuring with them and hand over the results.
Bluebeam Revu
Measuring, marking and comparing drawings on screen.
PlanSwift
Takeoffs made from ready-built assemblies, with quantities you can export.
On-Screen Takeoff
Layer-based measuring on big commercial drawing sets.
Rawlinsons-benchmarked rates
Up-to-date Australian unit rates, compared with supplier and subcontractor quotes.
Microsoft Excel
The final file, set out to match your cost codes and trade sections.
If you use Buildsoft, CostX, Estimate One, Procore or your own template, let us know and we will prepare the file so it imports straight in.

Cost vs. Capacity
Why Builders Hand Bim Estimating to Us
A full-time estimator is a salary, super, software seats and training. A BIM takeoff from us is a per-project cost that only appears when you are actually tendering.
- No software licences. Takeoff and cost-data subscriptions cost thousands of dollars per user each year. With us, you use ours.
- Tender more, more selectively. Most builders do not lose jobs through bad pricing. They lose them because they run out of time to reach enough tenders before closing.
- Site time stays site time. Items get overlooked when estimating at 9pm after a long day on site.
- Independent accuracy check. Even builders with in-house estimators use us to sanity-check large or unfamiliar BIM scopes before they submit.
- Moves up and down with how busy you are. Five takeoffs in a busy month and none in a slow one. You never carry a fixed cost.

Sample Output
Sample Line Items
Every estimate has this much detail: quantities tied to elements and measured in metric, never lump sums.
| Item | Unit | Qty | Material | Labour | Total |
|---|---|---|---|---|---|
| Slabs | m³ | 620 | $ | $ | $ |
| Walls | m² | 3,100 | $ | $ | $ |
| Doors | No. | 120 | $ | $ | $ |
These example items show only the layout and units. They do not come from a client project.
FAQ
Common Questions
Which model formats do you use?
IFC and Revit.
Do you rely on the model alone?
No. We always compare the model with the 2D drawings.
Can you price model revisions?
Yes.
Do you give modelling feedback?
Yes.
Which states and territories do you cover?
Every one. Prices are set for your project postcode and state, so a job in Darwin and a job in Melbourne get their own unit costs instead of one national average.
What does it cost?
A fee is quoted per project, in AUD excluding GST, before any work starts. You approve it in writing first. There is no hourly billing and no invoice larger than the quote.
How fast is turnaround?
Standard scopes ship in 24 to 48 hours. Large packages take 48 to 72 hours. If you are against a closing time, say so when you upload and we will tell you honestly whether we can meet it.
Are my project details kept confidential?
Yes. We keep drawings, specifications and tender figures private, and if you prefer we will sign your NDA before we receive any documents.

Ready for Your Next Bim Tender?
Send your drawings along with a short note on what the job covers. A fee and delivery date come back the same working day, and the finished estimate follows within one to two days of your approval.
