Client Departments-offices initially make a business case to the Department of Finance seeking sanction in principle to approach OPW with a request for accommodation for specific requirements. Efforts to identify a property solution, based on a detailed brief of requirements are then initiated. All options are fully explored, that is, the State portfolio, locally, on the market, the wider public service and advertisements are placed if necessary. A full technical evaluation of all potentially suitable options is completed, which can comprise reports from architects, engineers — structural, and mechanical and electrical, fire and security. Valuation reports are commissioned from either staff valuers or consultant valuers on suitable options. Planning advice and archaeology reports are also sought where appropriate. Title is checked by the Chief State Solicitor. On the basis of the relevant technical, valuation and other reports, a preferred option is identified. Sanction is then sought from the Department of Finance to proceed with the acquisition.
