The six countrywide national monument depots are authorised to order work or materials. At present three quotations are usually sought for works or supplies above an estimated cost of £500. Materials of a specialised nature are often required in relation to conservation works and the clerk of works in each depot may order such materials-services from individual contractors up to a value of £2,000. These procedures have proven satisfactory over a long period of time.
Audits of the stores management system at Dúchas depots are undertaken from time to time by this Department's internal audit unit, as part of annual audit programmes agreed within the Department. These systems are, of course, also subject to audit by the Office of the Comptroller and Auditor General.
