Bill of Quantities (BOQ) Analysis with AI
A bill of quantities (BOQ), or Leistungsverzeichnis, is only as useful as it is complete. Missing quantities, vague specifications, and ambiguous positions are where budgets slip and change orders are born — and spotting them by reading hundreds of line items by hand is slow and error-prone.
Maxi.Build AI reads the whole document for you. Drop in a BOQ as a PDF, a GAEB file, or an Excel export, and the AI extracts every position, groups it by section, describes the scope, and hands you a structured critique of what to fix before a single supplier sees it.
Key features
- Reads PDF, GAEB, and Excel — structured GAEB files (X83) are parsed directly without OCR; scanned PDFs and spreadsheets are read with AI OCR, no template setup
- Line-item extraction grouped by section — every position with its quantity, unit, and section subheading, ready to review and edit
- Scope summary and per-section descriptions — a plain-language overview of what the BOQ covers, section by section
- Three-way critique — the AI returns suggestions (what to clarify or fix before sending), highlights (large or unusual positions worth attention), and pitfalls (contradictions, missing information, and likely change-order traps)
- Procurement-readiness analysis — an on-demand report that classifies the document (true BoQ vs. BOM vs. specification), identifies trade packages, lists missing information needed for accurate pricing, and recommends how to package it for suppliers
- Auto-drafted request for quotation — analyzing a BOQ automatically creates a draft RFQ from the extracted positions, so you go from document to sourcing in one step
How it works
- Upload the BOQ. Add your bill of quantities from the BOQ page as a PDF, GAEB X83, or Excel file. Structured GAEB skips OCR and goes straight to extraction.
- AI extracts and structures it. Every line item is pulled out and grouped under its section, with quantities and units normalized.
- Read the critique. Review the scope summary, the per-section descriptions, and the suggestions, highlights, and pitfalls the AI surfaced — fix the gaps while the document is still yours to change.
- Run the procurement-readiness analysis. For a deeper pass, generate the markdown analysis: document classification, trade packages, missing-information checklist, and recommended RFQ packages.
- Move to sourcing. A draft request for quotation is created automatically. From here you can generate an AI budget estimate or prepare and send the RFQ to suppliers.
Who it's for
BOQ analysis is built for procurement managers, estimators, and site managers at construction firms who receive bills of quantities they didn't write — and need to know, fast, whether a document is complete enough to price. The AI does the tedious line-by-line reading so you can catch the expensive gaps before they reach a supplier.
