Before you start
Legible dated plans, available sections, work scope and measurement conventions. Missing dimensions are not measurements.
Construction takeoffs with Claude: make plan quantities traceable →
1. Download the native pack
Keep the complete ZIP without extracting it. If already installed and enabled, skip to step 3.
Download the ZIP pack ↓2. Install and enable in Claude
In Customize > Skills, use + > Create skill > Upload a skill to import the ZIP, then enable it. Check code execution and file creation. Attaching Markdown to a chat does not install a skill.
3. Prepare the inputs
Identify the drawing version and zones. The pack sometimes defaults to 2.40 m: keep that assumption distinct from read dimensions and unpriced until approved.
4. Request the file and its assumptions
Request detailed takeoff and summary sheets. A zero marked “to confirm” means unknown, not no work. Leave pricing for the estimating step.
A request to try
Use my metre-btp skill on the attached drawings. Produce the .xlsx by room with units and drawing references. Do not turn illegible dimensions into measurements. If proposing a 2.40 m height, mark it as unapproved. Separate unknown quantities from the confirmed total and list further measurements needed. Do not add prices.
5. Check the result
- Trace each quantity and unit to its source.
- Check areas, counts and linear-to-area conversions.
- List unknown zeros and assumed heights before pricing.
