The OPW ensures the quality of the concrete blockwork used in all its building projects complies with the European standard for masonry blockwork. This requires that the manufacturer shall supply a certificate with each delivery of concrete blocks stating the date of manufacture and that the blocks comply with all the requirements of the standard. It includes a declaration of performance and a European certificate marking and is in accordance with the technical guidance documents. Where a building shows cracks that may be consistent with the presence of a deleterious material, an inspection is carried out by a suitably qualified engineer. Appropriate sampling and testing may be carried out as required on a case by case basis. There are no buildings under the responsibility of the OPW in Donegal that have been identified to have this issue, to the best of my knowledge.
