In relation to the concrete blocks, the relevant suite of harmonised standard facilitating specification of masonry units is the EN 771 (series). ‘I.S. EN 771-3:2011+A1:2015’ deals with aggregate concrete masonry units. In this regard, the National Standards Authority of Ireland (NSAI), has published additional guidance in the form of ‘S.R. 325:2013+A2:2018/AC:2019 Recommendations for the design of masonry structures in Ireland to Eurocode 6’ which sets out appropriate minimum performance levels for specific intended uses of, inter alia, EN 771(series) in Ireland.
In respect of aggregates for concrete, NSAI has published ‘S.R. 16:2016 Guidance on the use of I.S. EN 12620:2002+A1:2008 - Aggregates for concrete’ which outlines the precautions to be taken in the quarry to reduce the risk of harmful impurities in aggregate production, including the requirement for independent third party oversight of factory production control by a Notified Body (a designated body that carries out third-party tasks).
Specifically relating to product legislation, since 2013, the Construction Products Directive (CPD)- 89/106/EEC has been replaced by the Construction Products Regulation (EU) No 305/2011 (CPR). It sets out rules for the marketing of construction products in the EU. Where a construction product covered by a harmonised standard is being placed on the EU market, the CPR requires the manufacturer to draw up a ‘declaration of performance’ and affix a ‘CE’ marking to the product. In order to do so, manufacturers must test and declare the performance of their construction products using a common technical language prescribed in the harmonised standard.
The manufacturer is responsible for compliance with the Construction Products Regulation (CPR) and in particular for the Declaration of Performance/CE marking of the construction product he/she is placing on the market, having full knowledge of the raw material (as is legally required by the CPR via the relevant harmonised European Standards) and having regard to the end product’s suitability for use in construction works in accordance with the relevant Standard Recommendations published by the NSAI.
Under the European Union (Construction Products) Regulations 2013 (S.I. No.225 of 2013), each of the building control authorities have been designated as the principal market surveillance authorities for construction products that fall within the scope of the CPR, within their administrative areas. In addition, Dublin City Council has been appointed as a competent authority for the carrying out of market surveillance functions across the country and has created a Market Surveillance Unit within Dublin City Council-National Building Control Office, (DCC-NBCO). Building control authorities will liaise with DCC-NBCO national market surveillance unit to support compliance with the CPR and to determine appropriate action on enforcement matters, as they arise.
The National market surveillance programme 2021 provides specific details on the market surveillance of construction products and outlines a market surveillance campaign led by DCC-NBCO, which has recently commenced, to perform risk assessments of selected quarrying and pit operations, follow-up inspections, sampling and testing as appropriate to ensure compliance with the CPR.
