• European Technical Assessments
• Assessment and Verification of Constancy

• Degree of 3rd Party Certification
• Notified bodies
• Declaration of Performance (DoP)

Construction Products Regulation
Seven Basic Requirements for Construction Works
1) Mechanical resistance and stability (No collapse, large deformations, damage to other parts, robustness)
2) Safety in case of fire (reasonable period, limited spread of fire and smoke, safe means of rescue)
3) Hygiene, health and the environment (no toxic gas, no dangerous particles or gases in the air, no emissions of radiation, no pollution of water or soil, no faulty elimination of waste, no damp)
4) Safety in use (reduce slipping, falling, collision, burns etc.)
5) Protection against noise (kept to a level that will not threaten health)
6) Energy saving and heat retention (energy in use shall be low)
7) Sustainability
Construction Products Regulation
Harmonised Standards
Written by CEN
Based on a mandate from the EC
EN 1090-1 based on Mandate M/120
Give the performance characteristics required
for products to allow works to meet the ‘Basic
Requirements for Construction Works’.
Most harmonised standards based on the CPD
Harmonised standards are under review to be
aligned with the CPR

Article 15
‘An importer or distributor shall be considered a manufacturer for the purposes of this Regulation

Governing Principles
• Execution Class is a design issue.
• The choice should be made before the start of
fabrication
• Execution Class should be based on the following three
conditions:
– The required reliability
– The type of structure, component or details; and
– The type of loading
• EXC4 reserved for special structures
• Limits placed on EXC1
• If not specified EXC2 applies

No guidance on the scope of application of EXC1 is given
EXC1 not endorsed for general use
NA.2.27.3, Note 2:The use of EXC1 generally provides a lower level of assurance of attaining the design resistance values in BS EN 1993. If the proposed specification of EXC1 by a specified, either in full or in part, does not take this into account, its use might result in a higher probability of structural failure than is normally accepted for most structures in the UK.

CE Marking 30th June 2016
BS EN 1993-2 and its National Annex:
recommends that bridges should normally be treated as medium consequence structures -i.e. Consequences Class 2
Lower or higher consequences may be considered for individual structures
Generally EXC3
Consequences Class - Bridges
Consequences Class – Towers and masts
Reliability
Class
Description
3 Towers and masts where the economic or strategic consequences
of failure would be likely to be severe.
N.B. This is likely to include most towers and masts located where
their failure is likely to cause injury or loss of life.
2 All towers and masts that cannot be identified as Class 1 or 3.
N.B. This might include manned sites or sites adjacent to
roads/railways in open countryside, provided the consequences of
a failure, especially risk of injury, are likely to be small.
1 Towers and masts, the failure of which would not be likely to cause
injury to people, e.g. Towers and masts built on unmanned sites in
open countryside
Note. The choice of reliability class (and hence the partial factors in Table NA. 4) has to be as agreed
between the designer, the client and the competent authority. In assessing existing structures
interpolation between the reliability classes, and thus interpolation between the partial factors in Table
NA. 4 may be used.
Consequences Class – Chimneys
Reliability
Class
Description
3 Chimneys erected in strategic locations, such as nuclear power
plants or in densely populated urban locations. Major chimneys in
manned industrial sites where the economic and social
consequences of their failure would be very high.
2 All normal chimneys at industrial sites or other locations that
cannot be identified as Class 1 or Class 3.
1 Chimneys built in open countryside whose failure would not cause
injury. Chimneys less than 16m high on unmanned sites.
Consequences Class – Silos
Reliability
Class
Design situation
3 Ground supported silos or silos supported on a complete skirt
extending to the ground with capacity in excess of W3a tonnes.
Discretely supported silos with capacity in excess of W3b tones.
Silos with capacity in excess of W3c tonnes in which any of the
following situation occur:
a) Eccentric discharge
b) Local patch loading
c) Unsymmetrical filling
2 All silos covered by this standard and not placed in another class
1 Silos with capacity between W1a tonnes(1) and W1b tonnes
(1) Silos with capacity less than W1a tonnes are not covered by this standard
Consequences Class – Silos cont.
A higher Consequences Class may always be adopted than that
required
The choice of relevant Consequences Class shall be agreed
between the designer, the client and the relevant authority
Consequences Class 3 should be used for local and patch
loading, which refers to a stored solids loading case causing a
patch load which extends round less than half the circumference
of the silo, as define in BS EN 1991-4.
For Consequences Class 1, simplified provisions may be
adopted (see Annex A if BS EN 1993-4-1)
Consequences Class – Tanks
Consequences
Class
Description
3 Tanks storing liquids or liquefied gases with toxic or
explosive potential and large size tanks with flammable or
water-polluting liquids in urban areas. Emergency loading
should be taken into account for these structures where
necessary, see annex A.2.14 of BS EN 1993-4-2.
2 Medium size tanks with flammable or water-polluting liquids
in urban areas.
1 Agricultural or tanks containing water.
The choice of the relevant Consequences Class shall be agreed between
the designer, the client and the relevant authority.
Consequences Class - Pipelines
BS EN 1993-4-3 provide the following guidance on the
choice of reliability class:
‘The choice of minimum reliability should be agreed
between the designer, the client and the relevant authority.’
Other Structures
The National Annex to BS EN 1993-1-1 recommends that for structures where guidance on the selection of Consequences Class and Reliability Class is not given in BS EN 1993, it should be assumed that the design rules in BS EN 1993 are safe for Consequences Class and Reliability Class up to CC2 and RC2.
