Build a price breakdown with traceable quantities and visible incomplete items.
Prepare the documents
CCTP, dimensioned drawings or explicit measurements, item codes, supplied prices and identified options.
Name files with dates and revision IDs. Identify approved documents and templates. The pack supplies a method; project facts must come from your documents.
Organize the work with ChatGPT
Create one row per priced service linked to its CCTP article. Preserve unit, quantity, measurement method, unit price and status. The pack specifies DPGF, MÉTRÉS, SYNTHÈSE, SOURCES and À_CONFIRMER sheets. Separate options from base scope; missing data leaves an item incomplete.
A fictional example to test
Fictional example: item P01, 10 m² at €25/m² excluding tax; P02 has no quantity. The first total must be €250. The second stays blank and the summary flags an incomplete item, without applying an unspecified tax rate.
Review the deliverable
Test a complete row and a blank row. Check units, duplicates, CCTP references and formulas; partial subtotals must be identifiable.
Request the editable file, open it and compare it with sources before approval. File creation depends on tools available in your session. This pack uses French instructions and deliverables; the linked skill page explains importing it and includes a copyable request.
