Using different procurement models where they are best suited should ensure that government can maximise the benefits from infrastructure. This analytical framework is designed to develop insights into the merits and shortcomings of procurement models. It requires a robust evidence base of costs and benefits, and data is key to gaining a better understanding of infrastructure investment outcomes. Data collection has been best on privately financed projects. Analysis of costs and benefits of procurement models enables transparency and public accountability, so data for traditionally procured projects needs to continue to improve.

This document sets out the National Infrastructure Commission’s summary findings from the pilot application of the analytical framework for assessing procurement models set out in the National Infrastructure Assessment. The Commission collaborated with Highways England on the pilot, using data from five road projects delivered by private financing and traditional procurement. A separate Technical Annex presents the methodology and findings from the pilot of the analytical framework.
