Published award criteria (3)
- Technical: The award criteria for this procurement are defined at the ITN (Invitation to Negotiate) stage and are based on selecting the Most Advantageous Tender (MAT)-i.e. the best overall balance of quality and cost, not simply the lowest price. Overall Award Approach (MAT) • The contract is awarded to the bidder with the highest total combined score across: o Technical o Commercial (price/value for money) o Legal (terms & conditions) • Scores are weighted and aggregated to 100% to identify the winning bid. In practice: • Technical quality is usually the most significant driver. • Price/value is also critical and can be heavily weighted. • Legal compliance is smaller but can still materially impact the score. • Technical Award Criteria • Technical scoring evaluates how well the solution meets requirements and delivers value. It includes: • Core areas assessed: • Solution specification & functionality • Implementation & delivery model • Integration capability • Data & reporting • Security & compliance • User experience • Innovation & continuous improvement • Mobilisation / transition approach
- Commercial: Commercial scoring assesses value for money: • Bids are ranked from lowest price (most competitive) to highest • The lowest price gets full commercial marks • Other bids are scored relative to that lowest price
- Legal: Legal Award Criteria • Legal scoring (typically ~5%) evaluates: • Acceptance of terms and conditions • Impact of any derogations (exceptions) • Key factors: • Risk transfer to Thames Water • Commercial/legal balance • Acceptability of proposed changes • Severe or poorly justified deviations can: • Reduce score significantly • Potentially invalidate the bid if unacceptable
- Price carries 25 of 100 points: a 10% discount moves about 2.5 points. The method statement decides this lot, not the discount.
Price arithmetic assumes straight proportional scoring; the tender pack may use another formula.
