Most margin is lost before a single worker sets foot on site.
Buried BOQ discrepancies, scope gaps that slip past under pressure, and supplier quotes that don't survive contact with a real programme — these are the leaks that erode a project's commercial position quietly, before the bid is even submitted.
QuarryRook was built for estimators, quantity surveyors, and commercial managers who need to answer one question with confidence before bid day: what could make us lose money on this tender?
Three modules. One commercial view of your tender.
Each module interrogates a different layer of tender risk. Together they give your commercial team a full picture of margin exposure before bid submission.
Surface every hidden risk before bid day.
The risk register identifies, categorises, and scores potential cost threats across your tender documents. Each finding is classified by severity, linked to its source, and presented with a commercial impact assessment.
- Quantity discrepancy flags with source references
- Scope gap identification with contract clause mapping
- Ambiguous specification alerts
- Severity scoring: High / Medium / Low with financial exposure
| Ref | Risk Item | Severity | Exposure |
|---|---|---|---|
| R-001 | M&E spec conflict with BOQ qty | High | €28,400 |
| R-002 | Provisional sum undefined scope | High | €14,200 |
| R-003 | Subcontractor quote currency mismatch | Medium | €6,800 |
| R-004 | Drawing revision vs. BOQ discrepancy | Medium | €4,100 |
| R-005 | Liquidated damages clause ambiguity | Low | TBD |
| Item | Qty | Unit | Rate | Total | Flag |

Every line item interrogated for commercial risk.
QuarryRook reads your Bill of Quantities and benchmarks every line against project scope, drawing revisions, and supplier data. Anomalous quantities, mispriced items, and missing allowances are flagged before they become costly variations.
- Quantity verification against drawing take-offs
- Unit rate anomaly detection
- Missing or provisional sum identification
- Line-item risk flag with commercial impact
Forecast margin. Quantify what you stand to lose.
The Margin Intelligence module aggregates risk exposure across your tender and models the impact on your bid margin under conservative, mid-range, and downside scenarios. Submit with your eyes open.
- Gross margin forecast vs. identified risk exposure
- Scenario modelling: base / conservative / downside
- Supplier and subcontractor cost validation
- Go/no-go recommendation with supporting data

From tender documents to commercial intelligence in four steps.
QuarryRook is built around the workflow your commercial team already uses. There is no re-training, no new project-management process to adopt — just structured intelligence layered onto your existing tender cycle.
Create a tender
Enter the project name, contract value, and bid date. Attach your Bill of Quantities, drawings package, and any supplier or subcontractor quotes you have received. QuarryRook supports PDF, Excel, and CSV formats.
Typical upload: 2–4 documents · Formats: PDF, XLSX, CSV
Analysis runs automatically
QuarryRook's analysis engine reads your documents, cross-references quantities against drawings, benchmarks unit rates, and identifies scope gaps, ambiguous clauses, and price anomalies across the full tender package.

Review the intelligence report
Your commercial intelligence report presents every finding in priority order — highest-exposure risks first — with source references, severity classifications, and quantified financial impact where calculable. Every flag is traceable back to the document and clause that generated it.
Findings: Severity-ranked · Source-linked · Financially quantified
Submit with clarity
Decide how to handle each risk: price it in, qualify it out, or raise a pre-bid query. The margin forecast updates as you resolve findings, giving you a live view of your adjusted commercial position right up to bid submission.

Questions from commercial teams.
What file formats does QuarryRook accept?
QuarryRook accepts PDF, Excel (XLSX, XLS), and CSV files for Bills of Quantities, drawings schedules, and supplier quotes. You can upload multiple documents per tender and combine formats — for example, a PDF drawings package alongside an Excel BOQ.
How is QuarryRook different from an estimating tool like Causeway or CostX?
Estimating tools help you build your cost plan from scratch. QuarryRook analyses a tender package you already have and interrogates it for risk — quantity discrepancies, scope gaps, ambiguous clauses, and mispriced lines. It is a commercial intelligence layer that sits alongside your existing estimating workflow, not a replacement for it.
Who is QuarryRook designed for?
The primary users are estimators, quantity surveyors, and commercial managers at SME general contractors — typically businesses bidding on commercial, residential, and mixed-use projects. Managing directors and commercial directors use the dashboard for pipeline visibility and margin oversight across multiple live tenders.
How are risk severity levels determined?
QuarryRook classifies each risk finding as High, Medium, or Low based on a combination of factors: the financial exposure relative to contract value, the contractual certainty of the item, and the recoverability of the cost if the risk crystallises. High findings always include a recommended action and a financial impact estimate where the data supports one.
Is our tender data kept confidential?
Yes. Each account's tender data is isolated at the database level — other accounts cannot access your documents, findings, or margin data. Documents are stored encrypted at rest and in transit. Your tender data is not used to train any shared model or shared with any third party.
What happens if a document cannot be parsed?
If a document cannot be fully parsed — for example, a scanned PDF without machine-readable text — QuarryRook will flag the affected sections rather than silently skipping them. You will see exactly which elements were extracted and which required manual review, so you know the analysis is complete.

The tender you are about to submit
already contains risks you cannot see.
Commercial intelligence is not a luxury for large contractors. SME contractors lose money on tenders that look profitable on the surface. QuarryRook changes that.
