You can take off a renovation with no drawings at all by importing a scaled A3 grid page into Wunderbuild and measuring against it. It takes about five minutes to set up, and from there the takeoff behaves exactly like one done over a real plan — areas, linear metres and spacing settings all work, and the measurements link straight back to your estimate items. This is a recap of our live training session from 29 October 2026, where Jacob worked through that technique along with two others builders ask about constantly: adding your own items and allowances to the Detailed Builders Template, and applying your own carpentry labour rates without breaking the template's price links.
Every construction software vendor has added "AI" to their marketing in the last 18 months. Most of it is overstated. Some of it is genuinely useful. And the gap between the marketing and the reality is wider than in any other category of construction technology right now. This article cuts through the noise. It maps the AI landscape into four distinct categories, explains what each actually does today (versus what marketing suggests), and recommends where Australian builders should and shouldn't be investing attention right now. The Four Categories of AI in Estimating When people say "AI in estimating," they mean wildly different things. The category matters more than the buzzword — each category has its own maturity, its own ROI profile, and its own pitfalls.
A builder we work with quoted a renovation at $480,000. The job ran over by $34,000. When we audited what went wrong, the answer wasn't bad pricing — every line item that was priced was priced accurately. The problem was that 11 line items weren't priced at all because they weren't in the scope of works. None of them were huge individually. Together they were a 7% margin loss the builder couldn't recover.
