The risk that an asset can be designed and built on-time, on-cost and to-specification. These risks should clearly be the responsibility of the Provider who should have the appropriate skills and experience to mitigate them. The public sector could mitigate these risks on its own projects by employing the same device as the Provider, i.e. the fixed-time, fixed-cost, fixed specification turnkey contract. However, historically it has not used this type of contract and public-sector procurement has a history of large capital-cost overruns.
