The first estimate said 120–140 square metres of panels. The drawing itself said 37.

That gap came from a real façade project, and it is the whole argument for this article. In façade contracting, the price of a tender rests on how well someone reads a drawing. Read it a little wrong and the quote is either too high to win or too low to make money.

How quotes usually get made

Every quote starts with a drawing from the client's designer. An estimator opens it, measures each panel, arch and cornice by hand, and types the quantities into a costing spreadsheet. The spreadsheet turns quantities into a price. Then someone retypes the result into a quotation for the client.

That process has three weak points. It takes days, so tenders queue up behind the one or two people who know the spreadsheet. Every retyping step is a chance to drop a line or shift a decimal. And measuring by eye is hard on modern façades: curved frontages, repeated arch families and panels split across several layers are easy to miss or double count.

What we built

We worked with a façade contractor and precast manufacturer that has factories and sites in two countries. Instead of asking the estimators to measure faster, we connected the drawing software directly to the company's business system.

  • One command inside the drawing. The drafter selects an elevation, or the whole drawing, and sends it. Nothing is exported by hand.
  • Exact geometry, not a picture. The program reads the drawing's own data: true areas including curves, lengths, panel blocks, dimensions and the material on each layer.
  • Take-off and panel numbers. Panels are numbered automatically, and a panel keeps its number every time the drawing is resent.
  • Priced with the estimators' own method. The quantities arrive in the business system as a draft quote, costed with the same method the estimators used in their workbooks.
  • Written back onto the drawing. The panel numbers and a panel schedule are drawn back into the file, so the drawing and the quote always describe the same panels.

Where people stay in charge

Automation here prepares work; it does not commit the company. Everything the bridge creates arrives as a draft. An engineer checks the quantities against the drawing, adjusts anything unusual and approves the price. If a drawing is ambiguous, the right answer is a question back to the designer, not a guess.

The drafting office has a part to play too. The program reads the layers the drafters use to separate materials, so a short, agreed drafting convention makes the take-off more reliable. On the first live drawing, reading those layers is exactly what corrected the 120–140 square metre estimate down to 37.

Security by design

Drafting PCs never hold a password to the business system. Each PC gets its own key that can do one thing only: submit a drawing. A key can be switched off in seconds if a PC is lost or someone leaves, and every submission is logged with the PC's name.

What changed

The estimators stopped measuring and retyping. A drawing becomes a priced draft quote in a fraction of the time it used to take, and the measuring is done from the drawing's own geometry rather than by eye. The estimators spend their time where judgement matters: checking unusual details, talking to designers and deciding the final price.

Is your team doing the same thing?

The pattern is not unique to façades. Any team that reads a document, copies numbers into a spreadsheet and retypes the result somewhere else is doing work a program can prepare for them. Start with one document type, keep a person approving the output, and measure the before and after on real jobs.
