A drawing brief that another team can work from.
A useful brief explains what is current, what must change and who can answer the questions. You do not need a polished presentation; you need a clear starting point.
1. Say what is happening at the plant.
Describe the upgrade, new equipment or documentation change. State the package boundary and the target issue date. Include the operational or shutdown constraint that makes that date important.
2. Identify the current information.
List the drawings, models, load lists and vendor documents you can provide. Record their revisions and mark which are current. If a scan, field mark-up or model may be incomplete, say so before it becomes an assumption in the drawing.
3. List the deliverables.
Use a drawing register. For each item, identify whether it is a new drawing, an update or a check. Include the native file format, PDF requirement, issue status and any related model or schedule.
4. Supply the project conventions.
Include the drafting standard, title blocks, equipment tags, symbols, layers and naming conventions. For a model package, include the BIM Execution Plan, coordinates, required content and exchange format.
5. Name the decision and review owners.
Who owns the design basis? Who answers technical queries? Who consolidates comments and accepts the issue? Identify calculations, site verification and statutory sign-off as separate responsibilities where they apply.
6. Agree how changes will move.
Set the review sequence, revision allowance and transmittal method. A changed design basis can affect several drawings; make sure the team can distinguish that from correcting a drafting error.
7. Define the handover.
List the native source files, PDFs, model exchanges, drawing register and revision information expected at completion. Agree the receiving team and acceptance criteria before the final issue.
Use the first conversation to find the gaps.
If you do not have every input, bring the list you do have. The point of scoping is to identify what can proceed, what needs a decision and what must be supplied before production.
Use the vendor checklist to compare proposals, or the BIM planning outline for a model package.
Put the scope on the table.
Tell us which documents need to change, which inputs are available and when your team needs to review them.
