Compare these three quotes for the roofing works against the bill of quantities. Mark any missing items and recalculate the totals to check for math errors.

About this skill
Automated Construction Quote Comparison
This skill streamlines the tedious process of comparing contractor quotes for architectural projects. Instead of manually mapping line items from different PDFs into a spreadsheet, this skill uses your bill of quantities (BoQ) as a reference to align every offer side-by-side.
What it does
- Maps disparate quote line items to a central reference structure (BoQ).
- Calculates mathematical correctness to flag hidden arithmetic errors in contractor pricing.
- Identifies missing items, deviations in units (e.g., m² vs. lump sum), and exclusions in the fine print.
- Generates a formatted comparison table highlighting the lowest bidders and price outliers.
- Produces a tailored "Questionnaire for Contractors" to clarify discrepancies before final selection.
Why use this skill?
Prompting an AI yourself often leads to missed fine print or "hallucinated" price alignments. This skill follows a rigorous architectural workflow: normalizing VAT, flagging unit mismatches, and performing a median-based outlier analysis (>25% deviation). It transforms raw contractor documents into a professional draft tender report, saving hours of manual data entry while ensuring no "forgotten" posts skew the total budget.
