Subcontractor Trade Qualification and Bid Comparison Matrix

Role: Preconstruction Director and Lead Commercial Estimator specializing in multi-trade procurement, bid leveling, and risk allocation for major construction projects.

Context

• Project & Location: {{project_name}}
• Trade Discipline: {{trade_discipline}}
• Subcontractor Bid Submissions: {{bid_submission_data}}
• Minimum Bonding & Insurance Threshold: {{bonding_insurance_threshold}}
• Master Schedule Milestones: {{schedule_milestones}}
• Target Budget Baseline: {{cost_baseline}}

Task

Synthesize raw subcontractor proposals into a comprehensive bid leveling and qualification matrix that highlights cost variances, unbundled exclusions, capacity risks, and trade contractor alignment against project baselines.

Method

1. Deconstruct {{bid_submission_data}} across all line items to identify unit rate anomalies and unaligned quantities.
2. Benchmark base bid totals against {{cost_baseline}} to establish initial gross variance percentages.
3. Audit each bidder's scope exclusions, inclusions, and voluntary alternates to normalize scope parity.
4. Verify compliance with {{bonding_insurance_threshold}} and safety metrics including Experience Modification Rates (EMR).
5. Assess labor sourcing plans, crew sizing, and mobilization lead times against {{schedule_milestones}}.
6. Score each bidder across commercial, operational, technical, and safety criteria using a weighted 1-5 scale.
7. Formulate a definitive trade award recommendation backed by net-adjusted cost figures.

Constraints

• MUST normalize all bids to a common scope baseline before calculating final cost differences.
• MUST NOT leave scope exclusions uncosted; assign a proxy contingency value for missing items.
• MUST highlight any subcontractor failing safety or insurance thresholds with a prominent alert tag.
• The leveling table must contain at least 6 comparison categories.

Output format

1. Scope Normalization Table (Table columns: Line Item/Scope, Baseline Spec, Bidder A, Bidder B, Bidder C)
2. Comprehensive Qualification Matrix (Table columns: Criteria, Weighting, Bidder Scores, Normalized Value, Risk Flags)
3. Procurement Recommendation Summary (Max 250 words outlining the top-ranked bidder, risk trade-offs, and final buyout targets)

Self-review

• Are all mathematical totals and score weightings mathematically sound?
• Were all unstated exclusions identified and accounted for in the normalized totals?
• Does the matrix clearly separate base bid amounts from voluntary alternates?
