Interior renovation
You upload the site survey and add your prices. You get the quote to send to your client and the DPGF framework for your subcontractors. Every quantity shows the calculation behind it and the measurement it comes from.
A site survey is uploaded. The system stops at the checkpoint, then delivers the seven finishing-works items, each quantity with its formula and source: the DPGF framework with an empty price column, and the quote priced with your rates.
The problem
Tuesday's site survey becomes the weekend's quote. Quantities are worked out by hand, item by item, and when the client disputes a line, all you have is your word. Whether you use your own crews or get subcontractors to price, the same work starts over on every job.
The survey goes into a spreadsheet, item by item. Nobody bills those hours, and a copying error only shows up on site.
Your client disputes a quantity. Without the formula and the measurement to hand, the negotiation is only about the total: you discuss a discount, not a line.
One groups plastering and painting, another splits them, the third forgets the skirting. The price gap no longer tells you anything about the scope gap.
Two files come out together, on every job.
The quote applies your unit prices to the calculated quantities, and every line says where its quantity comes from: that is what lets you answer when it is disputed. The DPGF framework — the standard French cost breakdown used to tender a job — carries the same lines with an empty price column: your subcontractors price an identical breakdown, and their offers become comparable. If you work with your own crews, it still comes out and you simply don't use it.
What goes in
A renovation job has no land to study: the building already exists. No zoning plan, no plot, nothing to process. What you provide, you already have: what you measured on site, and the prices you charge.
Your price list is entered only once: your unit prices are reused on every job, and you only touch them when they change. The same goes for your company details — SIRET number, ten-year liability insurance, consumer mediator, VAT.
And if you survey room by room — area, perimeter, height — the partition length is no longer estimated: it is measured. The quantities that depend on it move from “standard ratio” to “measured”. You type them in, or upload your survey sheet.
What comes out
First the DPGF framework: seven finishing-works items, on the example above. The price column goes out empty — it is for the contractors you consult to fill in. The quote comes out priced with your rates; it is described further down.
| Item | Description | Unit | Qty | Unit price | Confidence | Where the figure comes from |
|---|---|---|---|---|---|---|
| 01.1 | Removal of existing floor covering | m² | 80.00 | contractor | measured | area to treat = 80 m² · survey, page 2 |
| 01.2 | Removal of finishing-works debris | m³ | 4.00 | contractor | to check | 80 m² × 0.05 m³/m² · reference data — debris volume from stripping finishes, excluding structural demolition |
| 02.1 | Lining and plastering, walls and partitions | m² | 190.00 | contractor | standard ratio | 80 m² × 0.95 lm/m² × 2.50 m ceiling height · reference data — developed length of walls and partitions per floor area, typical partitioned dwelling |
| 03.1 | Floor covering, supply and installation | m² | 85.60 | contractor | standard ratio | 80 m² × 1.07 · reference data — offcuts and trimming on straight-laid covering |
| 03.2 | Skirting boards | lm | 76.00 | contractor | standard ratio | 80 m² × 0.95 lm/m² · reference data — developed length of walls and partitions |
| 04.1 | Painting of walls and partitions | m² | 190.00 | contractor | standard ratio | 80 m² × 0.95 lm/m² × 2.50 m ceiling height · reference data — developed length of walls and partitions |
| 04.2 | Ceiling painting | m² | 80.00 | contractor | measured | area to treat = 80 m² · survey, page 2 |
No total line in this file: adding m², m³ and linear metres means nothing, and as long as the price column is empty there is nothing to total.
It is a checking order. It tells you where to spend the five minutes you will give this take-off, rather than re-checking everything or trusting everything.
Of the seven items in this example, only one needs checking. That is more useful than a take-off that sounds equally sure of everything — and more honest.
The second file takes the same lines and applies your price list. It opens in Excel and is ready to send to your client.
What it doesn't cover
No electrical work, no plumbing.
These trades are counted in points — sockets, switches, supplies, drains — and their quantities can't be derived from an area. We don't produce them, and we would rather tell you before you open the file. If your job is mostly technical trades, this take-off won't help you.
A take-off is an order of magnitude, not a commitment.
It replaces neither your own pricing nor a joint survey by a quantity surveyor. It saves you the starting point, not the responsibility.
We never set a price, and we never will.
A quantity is calculated and proven; a price is decided and owned. We don't estimate, suggest or infer any price — no cost per square metre, no budget forecast. The quote applies the prices from your price list, the ones you wrote yourself: that is your margin, your risk and your trade. What we do there is a multiplication, and we show you the detail.
Privacy
Your projects are covered by agreements. We would rather tell you exactly what moves than promise you that nothing does.
Get started
Tip: start with a job you have already priced. You compare the take-off and quote you get with what you had worked out yourself.
Company name, email, password: one minute. Then you upload your survey, correct the sheet at the checkpoint, and download the take-off and the quote in Excel format.
