AI Budget Estimate from a Bill of Quantities
Before you send a bill of quantities to suppliers, you want a number: what should this cost? Building that budget by hand means digging through old contracts, past quotes, and half-remembered prices — and it goes stale the moment the next project starts.
Streckenheld AI builds the budget for you. From an analyzed bill of quantities it produces an internal offer — a priced estimate with one net unit price per position — sourced first from your own agreed prices and, where those run out, from current regional market prices. Every number comes with a note on where it came from.
Key features
- One priced line per position — quantity, unit, net unit price, line total, and a one-line source note for every item in the BOQ
- Prices from your own data first — the AI reads your framework contracts, previously received supplier offers, and past budgets before looking anywhere else
- Regional market fallback — where you have no internal price, it estimates current DACH/EU market prices, grounded with web search, and says so
- Transparent assumptions — a clear list of the price basis, date, region, and exclusions behind the estimate, plus a summary of which numbers came from history versus market
- Critique mode — if the BOQ already carries unit prices, the AI switches from estimating to reviewing: it validates each figure against history and market, flags outliers, and checks for missing accessories, transport, disposal, or scaffolding
- Editable line items — adjust any price, quantity, or description; add or soft-delete rows, with totals recalculated live
- Export as CSV, XLSX, or GAEB — download the final budget table for your ERP, a spreadsheet, or a priced GAEB (DA 84) file
How it works
- Start from an analyzed BOQ. Once your bill of quantities is analyzed, open the budget estimate panel.
- The AI agent works through the positions. It lists your available pricing sources — framework contracts, past offers, previous budgets — reads the relevant ones, and searches your recent estimates for similar work.
- It prices every line. Each position gets a net unit price with a source note; where no internal price exists, it uses a grounded market estimate.
- Review the assumptions and summary. Check the grand total, the per-section breakdown, and which prices came from your history versus the market — then edit any line you disagree with.
- Export or send. Download the budget as CSV, XLSX, or GAEB, or move on to sending the request for quotation to suppliers and compare their offers against this budget.
Who it's for
The budget estimate is for estimators, procurement leads, and commercial managers who need a defensible number early — to set a target, sanity-check a supplier quote, or decide whether a project is worth pursuing. It turns your accumulated pricing history and framework contracts into an instant, itemized budget instead of a spreadsheet you rebuild every time.
