Tender to priced bill, in an afternoon.
Drop in tender documents. Get a structured bill, takeoff, and rate build-up in one workflow. Return your priced bill in the exact format the main contractor sent.
CEM I → CEM III/B blastfurnace cement
BS 8500-1:2023 permits CEM III/B for foundation, marine, piling per cl. 03 30 00 / 2.1.A. Verify chloride exposure class XC4 for your supplier's mix.
Height exceeds maximum
Partition height 3660mm exceeds spec max of 3400mm cl. 4
Deflection head vs fixed fixing
Spec requires deflection head cl. 5.1 but item states fixed head
Six steps from tender to submission
From receiving tender documents to returning your priced bill — same structure, your rates.
Upload
Drop tender docs — PDF, XLS, DWG, ZIP. Auto-classified & OCR'd in minutes.
Process
Spec profiling, embeddings, summaries. Files become searchable knowledge.
Import bill
4-step wizard: source → analyse → detect structure → create the bill.
Takeoff
Calibrated lines, areas, counts grouped by item and linked to rows.
Rates
Apply parametric assemblies with material/labour/plant decomposition. Spec Intelligence reviews every row.
Export
Excel out in the exact format the MC sent — your rates, with a kgCO₂e column per category if the MC asks.
Catches what humans miss. Before it costs you.
Cross-references every line item against your uploaded specs — flagging discrepancies, missing items, and scope gaps with estimated cost impact and a clause reference for every call-out.
- Discrepancies. Bill-vs-spec conflicts with clause references and the corrected value side-by-side.
- Missing items. Spec requirements with no matching bill line — caught before you submit, not after the award.
- Scope gaps. Work not covered by either document — testing, certification, performance demonstrations.
- Low-carbon swaps. Spec-compliant substitutions (CEM I→III/B, GGBS, FSC timber, recycled steel) with kgCO₂e + cost delta, factors cited to ÖKOBAUDAT, ICE, MPA Fact Sheets and manufacturer EPDs — defensible for EPBD whole-life carbon from 2028.
- CSI MasterFormat aware. PART 1 / 2 / 3 awareness keeps the right issues in the right scope.
- Clause-aware chunking. clause_ref, parent_section, csi_part — every quote is sourced.
70S50 Gypframe C-stud → FSC C24 KD timber stud
NBS K10 cl. 5.2 permits "metal or treated timber stud"; fire rating EI 30 maintained with 12.5mm Gyproc both faces. Verify acoustic performance Rw ≥ 45 dB for separating walls per Approved Document E.
Acoustic sealant to perimeter
Spec calls for intumescent acoustic sealant at floor/wall/soffit perimeters cl. 6.3 — no matching bill row.
Structural performance certification
No allowance for BS 5234-2 testing or L/240 deflection verification. Likely required under PC obligations.
Height exceeds maximum
Partition height 3660mm exceeds spec max of 3400mm cl. 4
Material × labour × plant — decomposed for you
AI decomposes each item into components with parametric quantities pulled from your assemblies. Review, adjust, and build rates in seconds — not hours.
- Suggested components. Spec + library matching surfaces the most likely components for each bill row.
- Parametric quantities. Quantity formulas read from your variables — one rate, every size.
- Live unit cost. Updates as you tweak — see the impact of every change before saving.
Drop in an Excel or PDF bill. Get a structured estimate.
Four steps: source, analyse, detect structure, create. The row-type classifier and AI post-processing handle trade detection, spec extraction, and embeddings — so your bill lands ready to price.
An assistant that's read every spec, drawing, and schedule
Streaming chat over project docs with confidence-gated agentic search. Cited answers, query decomposition, and a drawing-list retrieval tool — no hallucinations on the rate.
- Cited sources. Every answer links back to the exact spec clause or drawing.
- Confidence scoring. Know when the model is sure, and when to double-check.
- Across all formats. One question, all documents — PDF, DWG, XLS.
- Drawing list retrieval. "Show me partition heads on the GF" — the right sheets, citation-ready.
- Carbon factors, auto-linked on import. When you bring a price sheet in, each product is matched to an A1-A3 factor from the seed library — MPA Fact Sheet 18 (cement), CARES UK avg (rebar), BCSA (structural steel), ÖKOBAUDAT 2024-I (concrete, plasterboard, mineral wool, timber). Source and version stick to the product; drop in a manufacturer EPD and it overrides the generic factor, with the citation carried through to the bill you return to the MC.
