Construction Skills for Claude Code
Open-source skills that give Claude Code the working knowledge of a Project Engineer. Split drawings, parse specs, tabulate bids, generate subcontracts, and more — directly from your terminal or IDE.
Prerequisites
- Claude Code (CLI, VS Code extension, or JetBrains)
- Python 3.10+
- Your construction project documents (drawings, specs, bids, etc.)
Setup
1. Install the skills:
# Global install (available in all projects)
git clone https://github.com/dleerdefi/claude-code-construction ~/.claude/skills/construction
# Or per-project install
git clone https://github.com/dleerdefi/claude-code-construction .claude/skills/construction
2. Run setup (installs Python dependencies into an isolated venv):
cd ~/.claude/skills/construction # or .claude/skills/construction
./setup
3. Connect to your project. Add this line to your project's CLAUDE.md:
@~/.claude/skills/construction/.claude/skills/CLAUDE.md
If your project doesn't have a CLAUDE.md yet, run /init in Claude Code first.
4. Start using skills. Open Claude Code in your project folder and type:
/project-setup
This inventories your project files, classifies document types, and establishes context for the other skills.
Skills
| Command | What it does |
|---|---|
/project-setup | Inventory project files, classify documents, establish context |
/sheet-splitter | Split a bound drawing set PDF into individual sheet PDFs |
/spec-splitter | Split a bound project manual into individual spec section PDFs + text |
/schedule-extractor | Extract door, finish, window, or panel schedules to Excel |
/submittal-log-generator | Parse every spec section and generate a submittal register in Excel |
/bid-tabulator | Tabulate multiple subcontractor bids into a comparison spreadsheet |
/bid-evaluator | Evaluate tabulated bids — scope gaps, risk scoring, award recommendation |
/code-researcher | Research applicable building codes, standards, and jurisdiction requirements |
/subcontract-writer | Generate a scope-specific subcontract from your firm's template |
AgentCM (Optional)
If your project uses AgentCM, skills automatically read from pre-indexed structured data in the .construction/ directory for faster results. Skills work without AgentCM using Claude's built-in vision and PDF tools.
Output
Skills save structured results to a .construction/ directory in your project root. Excel files, split PDFs, and extracted text are written to your project folder. Each skill reports its output location when complete.
Architecture & Technical Details
See CM Skills SOP for the full technical breakdown — skill architecture, design philosophy, YAML front matter spec, and the evaluation framework.

Requirements
Python dependencies are installed automatically by ./setup into an isolated venv at ~/.construction-skills/venv/. No manual activation needed — all scripts run through bin/construction-python.
Packages: pdfplumber, pymupdf, openpyxl, Pillow, PyYAML
