How it works
A project you talk to. A run you approve.
The structural discipline of construction, from drawings to quantities. A project holds one structural drawing set and keeps its own record, apart from every other. Every step is quoted before it spends, pauses where you tell it to, and leaves files with the evidence behind every number, which you can reopen at any time.
The walk
- 01
Read the drawings
Read every sheet, schedule and note; everything else builds on this reading.
Quoted before it runs, from the size of your drawings; you pay for what it uses. Ask in your own words, or type /ingest.
- 02
Project brief
The building on one page: storeys, structural system, what it is made of.
Quoted before it runs, from the size of your drawings; you pay for what it uses. Ask in your own words, or type /brief.
- 03
Material takeoff
Concrete, rebar and formwork measured line by line, with the evidence; the whole set or one sheet on its own.
Quoted before it runs, from the size of your drawings; you pay for what it uses. Ask in your own words, or type /takeoff.
- 04
Bill of quantities
Your accepted take-off as a tender-coded bill, ready to price.
Uses no credits: no AI work in this step. Ask in your own words, or type /boq.
- 05
3D model
An IFC model of your accepted take-off, ready for Revit or any BIM viewer.
Quoted before it runs, from the size of your drawings; you pay for what it uses. Ask in your own words, or type /3d.
- 06
RFI
The open questions for the designer, each with its evidence and the assumption taken meanwhile.
Quoted before it runs, from the size of your drawings; you pay for what it uses. Ask in your own words, or type /rfi.
- 07
RFI strategy
The open questions sorted by what the tender needs first, packaged to send.
Quoted before it runs, from the size of your drawings; you pay for what it uses. Ask in your own words, or type /rfi-strategy.
- 08
Project map
A map of the building: every element, its level, its sheet and its schedule row, linked.
Quoted before it runs, from the size of your drawings; you pay for what it uses. Ask in your own words, or type /knowledge-graph.
One lifecycle, every step.
Quoted
The quote names how thorough the reading will be and why, the credit range, the ceiling, whether earlier work is reused and whether running it again charges again.
Approved
You approve. The ceiling is held from your credits and becomes the run's hard budget.
Working
The run keeps its own room. You see each stage, what it is doing in plain words and the credits used so far.
Waiting for you
Where you asked it to stop, the run pauses. You accept, correct or reject each item against its evidence, then continue.
Done
You are charged for what it used and the rest of the hold comes back. The files and the evidence behind every number are kept with the run, and the result records which release measured it.
Stopped
A run that hits a problem on our side keeps what it finished; you pay only for the work it did, never more than the hold, and the rest comes back. Say carry on and it picks up from where it stopped.
Rejected at a review
The work already done is charged, never more than the hold, and the rest comes back. What you rejected is not charged. Declining a quote holds nothing and costs nothing.
Stopped by you
Stop it before it spends and nothing is charged. Stop it once it has done AI work and that work is charged, never more than the hold, and the rest comes back.
Effort
How thorough a step is. Independent of where it stops for you.
Light
The quickest pass at a take-off or a model, for the fewest credits
Standard
Every sheet read once; schedules cross-checked
Highest quality
Every sheet, every schedule, every note; how every reading runs
Deepest
Our most thorough pass for take-offs and models; you pay for what it uses, up to the limit you set for the run
When it stops for you
Where the run pauses for your decision. Automatic still obeys the spending cap.
Automatic
Works through to the end within what you approved; what it flags is shown to you, and nothing waits for you
Pause on major flags
Stops for your decision when the reading hits a major flag
Step by step
Stops after every stage until you continue
Questions people ask first
- Can AI read construction drawings?
- Structural ones, yes, with limits. detumble reads AutoCAD DWG and DXF sets: sheets, layers, schedules and notes, and shows you the reading to confirm before anything is measured. The measuring is then repeatable arithmetic from the confirmed reading, and nothing advances without an engineer's acceptance.
- Does it read PDF drawings?
- DWG and DXF today, or a zip of either. A take-off needs DWG or DXF; PDF sets are on the roadmap.
- What happens when the drawings disagree?
- The conflict is kept as a query with the assumption taken and what closes it, never silently resolved. You choose which queries become formal RFIs.
- What does a run cost?
- Every paid run is quoted before it spends a credit and runs only when you approve. Credits are reserved, metered and settled on actual use; unused credits come back, and a run is only charged for the work it really did.
The law every run obeys
- Nothing advances without your acceptance; every number carries evidence.
- Credits are held, metered and charged for what was used, and the rest comes back. A run is only ever charged for the work it really did, never above what you approved: one that hits a problem on our side keeps what it finished and carries on from there when you say so, and nothing done is charged twice; a run that needs more credits pauses and asks.
- Every project is kept apart from every other: its drawings, its record and its history. Someone who is not a member cannot see that it exists.
- Every result records which release measured it, so it can be measured again the same way.
