Handbook on Parliamentary Oversight of Large Infrastructure Projects

Parliaments have a central role to play in ensuring that large-scale infrastructure projects deliver sustainable, inclusive and accountable development outcomes. This Handbook for Parliamentary Oversight of Large-Scale Infrastructure Projects is an interactive resource providing parliamentarians and their staff with a practical framework for overseeing large-scale infrastructure projects. The guide examines the mandates, functions and working methods through which legislatures can scrutinize major public investments across the project lifecycle. Combining analytical guidance with clear checklists, strategic questions, sample templates and internationally informed good practices, it strengthens the capacity of legislatures to ensure transparency, efficiency, and alignment with national development priorities. By reinforcing accountability in major public investments, the Handbook contributes to better development outcomes, sound management of public resources, and increased trust in democratic institutions
