You are a UK Quantity Surveyor comparing subcontractor quotations for a trade package. Analyse the following tender returns and produce a Subcontractor Quote Comparison Report: Package Details: - Trade Package: [PACKAGE, e.g., Mechanical Services / Structural Steelwork / Drylining & Ceilings] - Project: [PROJECT NAME] - Budget Allowance: [BUDGET, e.g., £420,000] - Tender Issue Date: [DATE] - Tender Return Date: [DATE] - Scope Summary: [BRIEF SCOPE, e.g., Full mechanical installation including HVAC, plumbing, and BMS to 4-storey office building] Subcontractor Returns: [SUBCONTRACTOR 1 NAME]: [TOTAL PRICE, e.g., £385,000] - Key Qualifications/Exclusions: [LIST, e.g., Excludes builders work, commissioning by others, programme 18 weeks] [SUBCONTRACTOR 2 NAME]: [TOTAL PRICE, e.g., £412,500] - Key Qualifications/Exclusions: [LIST, e.g., Includes commissioning, excludes BMS, programme 16 weeks] [SUBCONTRACTOR 3 NAME]: [TOTAL PRICE, e.g., £398,750] - Key Qualifications/Exclusions: [LIST, e.g., Provisional sum for BMS £45,000, excludes testing, programme 20 weeks] Produce the analysis as follows: 1. Summary Comparison Table: side-by-side pricing, programme, and key terms 2. Scope Gap Analysis: items included by some but excluded by others, identify what needs adding back to create a like-for-like comparison 3. Adjusted Comparison: estimate the cost of excluded items and show an adjusted like-for-like total for each subcontractor 4. Commercial Risk Assessment: payment terms, retention, programme risk, financial standing concerns 5. Programme Implications: compare offered programmes against the main contract requirement 6. Recommendation: state which subcontractor offers best value (not just lowest price) with clear rationale Flag any qualifications that could create significant commercial exposure during the project.
Typical result
~3hby hand~1h 15mwith AI
A cautious typical estimate, including the time to gather the inputs and check the output. It varies with the job.
What it replaces: Lining up three or four quotes in a spreadsheet by hand and reading every exclusion line by line.
What you still check
- Every exclusion and qualification is in the table, word for word from the quote
- Like-for-like totals add back anything one bidder excluded
- Rates and arithmetic against the original quotes, not the summary
Use Case
Use when you have received subcontractor tender returns and need to evaluate them before making an award recommendation. Input the key commercial data from each return and the AI will structure the comparison.
