I would like to begin by acknowledging the work of the National Investment Office in organising this event. Since its inaugural annual conference in January 2020, presciently titled “Infrastructure in an Era of Uncertainty, through InfraNet, the NIO has brought together policy-makers, delivery agents, external experts and senior academics to consider topics such as regional balance, housing, climate change, and promoting value-for-money in capital project appraisal. They have also engendered a new network for delivery professionals who have been enabled to hear and learn from each other, ensuring that excellence in infrastructure delivery is embedded across the public service.
