The Commissioners of Public Works in Ireland (the Board of Commissioners) and their powers, duties and functions, as conferred on them by the Public Works (Ireland) Act 1831 and subsequent leglisation, are assigned to, and administered by, the Minister for Public Expenditure and Reform as the responsible head of the Board of Commissioners to Dáil Éireann. In that regard, the Office of Public Works, while a central Government Office, is a sub-office of the Department of Public Expenditure and Reform Office. The legal powers conferred on the Commissioners are exercisable only with the consent of the Minister for Public Expenditure and Reform.
