What is driving I.S. EN 1090?

• All public contracts

• Engineers, Architects

• Building Contractors

• Building Control Amendment Regulations 2013

• Competitors

CPR and Steel Fabrication

• I.S. EN 1090-1 Execution of steel structures and aluminium structures-Part 1 Requirements for conformity assessment of structural components.

• Came into effect on 1st July 2014

• Factory production control requirements.

5 April 24, 2015

When does EN 1090-1 apply?

The product is covered by the scope of EN 1090-1:2009+A1:2011,

The product is a structural construction product within the meaning of the Construction Products Regulation which means:

the product is intended to be incorporated in a permanent manner in construction works (buildings or civil engineering works), and

the product has a structural function in relation to the construction work (i.e. its failure will affect the satisfaction of Basic Work Requirement 1.)

The product is not covered by a dedicated European product specification.

Execution Classes

• I.S. EN 1090-2: 2008 Sets out four execution classes.

1. EXC1 – e.g. Agricultural Buildings

2. EXC2 – e.g. Residential or Commercial Buildings

3. EXC3 – e.g. Bridges

4. EXC4 – e.g. Special Structures (long span bridges)

Customer specifies the execution class, if not specified then EXC2 shall be applied. (EN1090-2 cl. 4.1.2)

Structural Design

In the case where structural design is carried by the manufacturer and design characteristics are declared as part of CE Marking, the manufacturer needs to establish procedures to control and verify compliance with the design brief, for checking calculations and for ensuring the competence of individuals responsible for the design.
