The information sought is not readily available as the systems used to track projects though the various lifecycle stages do not record the variance between Basic Unit Costs (BUCs) and approved construction budgets. Compiling the data requested would involve delivery teams mainly reviewing every project approved over the last three years, and this is not a feasible use of Department resources.
While my Department issues BUCs, which apply to social housing construction projects, these BUCs are not applied as absolute ceilings or limits. Rather, they are key benchmarks for developing and costing scheme designs at capital appraisal stage. BUCs are updated by my Department annually, based on an analysis of returned data, construction trends, and inflation.
Proposals for social housing construction projects are assessed by my Department on a case-by-case basis having regard to value for money, compliance with design guidelines, the Capital Works Management Framework, Infrastructure Guidelines, procurement procedures and most economically advantageous tender evaluations, as well as overall suitability, before budgets are issued to local authorities. As such any project that exceeds the BUCs has been thoroughly appraised and my Department has satisfied itself that the cost of construction is justified and necessary.
