M-01/DRAWING REVIEWSAMPLE

The tender drawings checked before you price, and the queries ready before the clarification deadline.

YOU SEND

The tender package: drawings, drawing register, specification and site investigation, with the date queries are due.

YOU GET

A tender clarification pack: a numbered tender query log in your format, the gaps and conflicts behind each query, the assumptions and exclusions to state in your tender, and key quantities.

  • 01Query logEvery question numbered and written ready to send, referenced to the sheet, revision and clause, in your query schedule format.
  • 02Gaps and conflictsSheets checked against each other, the drawing register and the specification: missing details, clashing dimensions, unstated grades, and notes that conflict with the specification, BS 8666 and the Eurocodes.
  • 03Assumptions and exclusionsWhere the drawings leave scope open, the basis to state in your tender, so the risk is priced or written down. Where the tender does not allow qualified bids, we turn them into queries instead.
  • 04Key quantitiesConcrete by element, reinforcement allowance by element, excavation and disposal, taken off the drawings so you can sense-check the scope before the full take-off.

We sign your NDA, or send ours, before any drawings change hands.

AI use in writing

Every deliverable states what AI did and who checked it.

Senior sign-off

Never used for training

Your drawings are used for your job only. They are never used to train AI models.

Before you send the drawings

Get your first review free

One package from a tender you're pricing now, such as substructure or drainage, up to 40 sheets: the query log, gaps and conflicts, assumptions and exclusions, and key quantities, within 3 working days of the complete package arriving, with a short call to go through them. Or send a tender you've already returned, and we'll check it blind so you can compare our quantities and queries with your own.

AI does the counting: reading each sheet, taking off the quantities, cross-checking the drawings and marking anything it can't settle. A senior engineer in the discipline resolves every marked item, checks the result and signs it off. Each deliverable states what AI did and who checked it.

The standard applies to RICS members and regulated firms. Arched is neither, so the duties sit with you, including due diligence before you use a third-party AI system and telling your client in writing when AI is used. We'll send you a short due-diligence note before you share any drawings: what our AI does on your package, how its output is checked and by whom, and how your files are handled. Every deliverable also states on its cover what AI did and who checked it.

Not yet. Our work is a check and a take-off for your estimators to use, and your team keeps responsibility for the price you submit. Our terms set out our liability, and we'll send them with the fee quote.

The one your tender specifies: NRM2 for building work, CESMM4 Revised for civil engineering and MMHW for highway works. Send your bill layout and we'll fill it.

A fixed fee per package, quoted within one working day of receiving the documents. Teams with a steady flow of tenders can take a monthly allowance instead. We don't charge by the hour.

Under NDA, signed before anything is sent. Your drawings are used for your job only and are never used to train AI models. Check your tender's confidentiality terms first: if sharing needs the client's consent, tell us and we'll give you a short description of our handling to send them.
