⚖️ Score blind — Step 3 of 5

You score anonymized proposals. Extreme scores are auto-pruned (>20% from median).

Acting Certified Evaluator

Target Anonymized Proposal

5 Standardized Sub-Criteria Rubrics (Total 0–10,000 bps)

1. Structural Durability & Engineering Rigor (0-2000 bps):

2. Environmental & Climate Resilience (0-2000 bps):

3. Project Timeline & Critical Path (0-2000 bps):

4. Personnel Accreditation & Track Record (0-2000 bps):

5. Quality Assurance & ISO Compliance (0-2000 bps):

Cumulative Technical Score: 90.00% (9,000 bps)

Olympic Trimmed Mean Filter >20% Pruned

The on-chain smart contract automatically drops maximum and minimum scores and permanently marks rogue evaluations deviating >20% from the median as is_outlier_flagged = true.

💰 Open prices & award — Step 4 of 5

Only qualified bids open. Best quality-price mix wins automatically.

Auto-math

Contractor Qualification & Unsealing Status

Advance through Technical Evaluation to unseal qualified financial quotations.

Solana On-Chain Award Formula:

S_composite = (S_tech × 0.70) + ((P_lowest / P_bidder) × 10,000 × 0.30)

The smart contract verifies that the winning contractor mathematically possesses the highest composite score. Submissions with higher pricing are proportionally penalized on the financial ratio.

Commercial Secrecy Defense Enforced
