Multifab Achieve CE Marking of Structural Steelwork

Contracts for fabricated structural steelwork to be delivered to site on or after 1st July 2014 must be CE certified. This certification includes the obligations of BS EN 1090-1 and BS EN 1090-2 on the steelwork contractor. It is therefore a legal requirement for all fabricated structural steelwork delivered to site to be CE marked.

BS EN 1090-1 requires that ALL structural material supplied conforms to BS EN 1090-2. The BCSA have developed a specific structural steel work specification for CE marking (NSSS V5 CE Marking Version) that incorporates the requirements of BS EN 1090-2. This requires that ALL Importers, Distributers, Manufacturers and Fabricators who change the original properties of a structural component are CE approved by an independent nominated body with a Factory Production Control System (FPC) and an ISO 9001 or equivalent quality system.

Changing the original properties includes but is not limited to, shot-blasting, painting, cutting, cold forming, drilling, flame cutting, bending, rolling, marking welding etc.

Our Obligations

In order to be able to CE Mark the fabricated structural steelwork that we produce, steelwork contractors are required to declare performance to the system 2+ level of assessment. This requires us to undertake:

Initial type-testing of the product

FPC, which will include:

  • Implementation of FPC system procedures
  • Appointment of a Responsible Welding Coordinator (RWC), if classified as execution class 2 and above
  • Implementation of welding quality management system (WQMS) procedures
  • Further testing of samples taken at the factory in accordance with the prescribed test plan

We must also be assessed by a notified body that will carry out:

  • Initial inspection of the manufacturing plant
  • Initial inspection of the FPC
  • Continuous surveillance, assessment and approval of the FPC, which will typically include: An annual audit to ensure continued competence to the declared Execution Class

The notified body will then issue a FPC certificate and Welding Certificate identifying the Execution Class that the steelwork contractor is approved to.

Execution Class (EXC)

BS EN 1090-2 introduces the concept of execution class. this enables Design Engineers to select the level of quality management suitable for the construction product and has a direct tie in with specified.

Execution Class System Level Type of Work Undertaken
EXC1 Elementary Quality System Farm Buildings
EXC2 Standard Quality System Buildings
EXC3 Comprehensive Quality System Bridges, Stadia etc
EXC4 Comprehensive Quality System Special Structures

Specification of an Execution Class (EXC for steel structures is a new concept within the steel construction industry. In BS EN 1090-2 these range from Execution Class 1 to Execution Class 4 (EXC1, EXC2, EXC3 and EXC4). The strictness of requirements increases from EXC1 to EXC4.

The choice of execution class is a design issue where each class is based on the criticality of a structure in terms of its service conditions and the consequence of its failure. However, whilst the designer is responsible for determining the required execution class, to enable CE Marking of its fabricated steelwork, a steelwork contractor must declare and demonstrate its capability to produce a structure that will conform to a specified execution class.

All material supplied with a CE mark be supplied to an Execution Class. The purchaser must specify the Execution Class required from the supplier.

The importance of a steelwork contractor declaring the correct Execution Class for its range of fabricated steelwork cannot be overstated, since this not only impacts on the stringency of the systems and competency of personnel used to implement and control its manufacturing operations but also the work to be tendered for. A steelwork contractor declaring conformance to a particular Execution Class can undertake work in a lower class but not to a higher class.

Multifab's Capability

Multifab have been accredited to Execution Class 2 (EXC2) and are currently implementing the necessary in-house charges to introduce the FPC & WQMS necessary to comply. Managing Director Franc D'Agnano stated "With our existing highly efficient in-house management systems already in place, the introduction of an FPC has been made a lot easier because of the level of recording and traceability that we already use. We now look forward to our further investments in Welder qualifications RWC training and plant improvements, reaping dividends for us as we look to broaden our involvement in the recovering UK construction sector."
