SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill automates construction quantity surveying from PDF construction plans, enabling rapid takeoffs, cost estimation, and professional reports while reducing manual effort and errors.

Core Features & Use Cases

  • PDF Plan Analysis: Processes site plans, floor plans, elevations, and details using Claude Vision to extract scale, dimensions, and annotations.
  • Quantity Extraction: Quantifies earthwork, concrete, steel, finishes, and more by CSI divisions.
  • Competitor Analysis: Scrapes leading takeoff solutions via Firecrawl to identify best practices.
  • Cost Estimation: Florida market unit costs and labor rates to produce detailed budgets.
  • Excel Reports: Multi-sheet workbooks with project summary, takeoff details, materials, and competitor insights.
  • Supabase Logging: Persist results for analytics.

Quick Start

Provide a basic instruction: "Upload a PDF plan to the takeoff workflow and specify project SPD-2025-003."

Frequently Asked Questions about construction-takeoff

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I extract quantities from PDF construction plans automatically?▼

PDF plan analysis uses Claude Vision to extract scale, dimensions, and annotations from site plans, floor plans, elevations, and details. The Skill quantifies materials by CSI MasterFormat divisions and generates itemized takeoffs, eliminating manual measurement and categorization.

Can I generate cost estimates from construction takeoffs?▼

Yes. After extracting quantities, the Skill applies Florida market unit costs and labor rates to produce detailed budgets. Results export to Excel with project summary, materials breakdown, and cost totals for stakeholder reporting.

Does this work with multi-page PDF plans?▼

Multi-page PDF support is built in. The Skill processes all pages within a single plan document, extracting and consolidating quantities across site plans, floor plans, elevations, and detail sheets into one comprehensive takeoff.

What file formats does the takeoff workflow output?▼

The Skill generates Excel-based multi-sheet workbooks containing project summary, takeoff details, materials lists, and competitor insights. Results also log to Supabase for historical analysis and tracking.

How do I track takeoff results over time?▼

Supabase logging persists all takeoff data and cost estimates, enabling historical analysis and comparison across projects. Store and query results to identify trends, benchmark costs, and audit past estimates.
