Including Star Rating Targets in the Tender Process
Including star-rating targets in the tender process raises the competitive bar among design teams. The open-ended ‘or better’ target invites designers to aspire to higher performance. A 4.5 star outcome can be given more weighting than a 3.5 star outcome for a very small percentage of the overall project costs.
Project evaluation criteria can therefore include the safety performance of a road in addition to traditional criteria like cost, time and quality. The star ratings and associated estimate of life-time crash costs associated with each design can provide an objective, evidence based, global standard that can be used in evaluation criteria. Refer to our simple tables below as a template for action.
For example tenderers could be ranked by their performance across all of the criteria and/or the costs of road trauma expected in their design could be included in the price evaluation. For example:
|Criteria||Tenderer 1||Tenderer 2||Tenderer 3|
|Safety Performance||2.8 Star||4.1 Star||3.7 Star|
|Safety Benefit (A)||$6 Million||$81 Million||$65 Million|
|Cost (B)||$112 Million||$125 Million||$123 Million|
|Total Cost (B – A)||$106 Million||$44 Million||$58 Million|
From a whole of government perspective, and for commissioning bodies making a long-term investment in roads and subsequent infrastructure maintenance, there is a powerful argument to pay for better and safer infrastructure at the outset instead of retrofitting at greater cost in coming years.
Safer roads will pay for themselves!
