    Scope of this presentation

  • European Construction Industry8% of European GDPEmploys approx. 20 million peopleUses approx. 8 million tonnes of steel

    Construction ProductsFrom steel lintels to steel frames for houses, schools, hospitals, supermarkets, stadia, high-rise buildings, including bridges etc

    European Constructional Steelwork Industry

  • Steelwork Industry - Market

  • Steelwork Industry - Rolling

  • Steelwork Industry - Fabrication

  • Steelwork Industry - Erection

  • Steelwork Industry Construction Products

  • Steelwork Industry Potumna road bridge, Galway

    Potumna bridge, Galway, Ireland Orginally built in 1911 First bridge in Ireland to be CE Marked Swing bridge Machinery Directive

  • Steelwork Industry View of CE Marking

    Supports the introduction of mandatory CE Marking for Safety Critical Construction ProductsImproves the Quality and Professionalism of the Construction industrySteel products such as beams and bolts already CE Marked, fabricated steelwork will come into force later this yearSteel industry is currently investing in the systems and training needed for CE Marking

  • Safety Critical, Bespoke, Large structures, long life

    Safety Critical, BespokeIn the interest of Public safety must have FPC systemExceptions Farm buildings, Silos etc

    Where do you put the CE Mark?On the product where too bigOn the packaging what packagingOn the commercial documents H&S documents

    Differences with other products

  • Differences with other products cont.

    How long should the manufacturer retain documents?Supermarket design life 25 yrsOffice design life 60 yrsBridge design life 125 yrsManufacturer 10 yrs?

    Who should retain the documents?Owner for the life of the structure

  • Limited to:1. Mechanical resistance and stability

    Material propertiesTolerancesLoad bearing capacity

    2. Safety in case of fireGeneration and spread of fireFire resistance period

    3. Hygiene, health and the environmentEmission of dangerous substances

    7. Sustainability of natural resourcesRecyclabilityDurability

    Essential Characteristics

  • The vast majority of structural steelwork products are bespoke, one-off components installed by the manufacturerThese products are safety critical (Attestation Level 2+ (1))Public Safety requires the manufacturer to have a FPC system certified by a notified bodyThis degree of independent certification will be lost If public safety is critical for series manufactured products, it is equally important for bespoke products

    CE Marking Article 5 Derogation

  • Embodied energySteel section 0.73 tonnes CO2/Tonne steelSteel fabrication 0.30 tonnes CO2/Tonne steel

  • Re-using existing steel sectionsSection size (geometrical properties)Steel material properties largely unknownTesting required frequency to convince the marketProtective paint systemPaint system may contain banned substancesCan re-used steel be CE Marked?

    Cant CE Mark reclaimed steel sections (manufacturers standard doesnt apply, sections on the market before CPD in force)Can CE Mark fabricated steelwork (fabrication standard applies, new construction product)

    Sustainability Re-use & CE Marking

  • Sustainability Re-use

  • Steelwork Industry Policing of CE Marking

    Concern that some manufacturers will supply without CE MarkingConcern that authorities do not have sufficient resourcesIndustry willing to set up an anonymous whistle-blowing system Central register of CE Marking manufacturers required

  • Summary

    Key Points:The Steel Industry supports CE MarkingMandatory CE Marking of safety critical products needed for public safetyManufacturer to retain documents for 10yrsOwner to retain documents for the life of the productSustainability needs considerationPolicing need a central register of CE Marking manufacturers
