This paper addresses the nebulous value for money (VfM) concept and its widely-criticised use in justifying the adoption of Public-Private Partnerships (PPPs) for transport infrastructure projects. It draws on the theories of value and identifies that value is generated in the interaction of the supply side (i.e., governments - as project sponsors and part of infrastructure delivery partnerships) and the demand side (i.e., end-users). In this sense, ‘public’ participation in transport is highlighted in the proposed framework to demonstrate that it is the combination of ‘traditional’ and ‘public’ VfM that together create a more meaningful VfM concept. To underpin the application of the framework, a dynamic VfM assessment process is developed that can facilitate the appropriate selection of a procurement method and assess its VfM throughout the project lifecycle. Unlike current examples, the framework is designed for both PPPs and their alternatives (e.g., conventional public sector procurement) and aligns ex-ante and ex-post VfM assessment. The enhanced model creates an opportunity for governments to recognise public VfM in transport interventions, shift their mindset from singular to multi-dimensional evaluation, and start to actually accumulate and exploit experience from past projects. As such, the contribution of this paper is twofold: (1) drawing upon theories of value, it depicts the ontology of VfM and addresses a missing ingredient in VfM assessment; and (2) it develops a holistic framework for the public sector to re-calibrate their VfM assessment policy when procuring transport projects.
