SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires openpyxl, and includes scripts (resource) and references (resource) components.

What problem does it solve?

Construction managers and engineers spend hours manually extracting data from multiple subcontractor bid PDFs to compare pricing, scope inclusions/exclusions, and contract terms, a process that is error-prone and delays buyout decisions. This skill automates end-to-end bid tabulation to produce consistent, review-ready comparison files.

Core Features & Use Cases

  • Full Bid Data Extraction: Captures all line items, alternates, qualifications, exclusions, and bidder details exactly as submitted, with no paraphrasing or data loss.
  • Formatted Excel Comparison Workbook: Generates a multi-tab spreadsheet with per-bidder detail tabs, cross-sheet formulas for automatic total calculations, a scope gap matrix to flag discrepancies, and a consolidated exclusions/qualifications view.
  • Use Case: For a drywall buyout with 12 subcontractor bids, use this skill to process all PDFs, automatically highlight the lowest and highest bids, flag scope gaps, and produce a single shareable file for engineer review.

Quick Start

Use the bid-tabulator skill to process all subcontractor bid PDFs for your current trade scope and generate a formatted bid comparison spreadsheet for review.
