3 Eurocodes are the suite of European Standards covering structural design of civil engineering works, including highways structures. Eurocodes are the published and maintained structural design standards in the UK. UK National Standards that were in conflict with Eurocodes have been withdrawn. Scope and This document gives guidance, advice and the requirements of the Overseeing Organisation on the use of Eurocodes for the design of HIGHWAY structures (including any associated geotechnical works) and aspects of execution relevant to the Eurocodes shall be used for the design of new HIGHWAY structures (including geotechnical works) in concrete, steel, composite concrete and steel, masonry, timber and Eurocodes shall not be used for the structural assessment of existing HIGHWAY structures that were not designed to Eurocodes.

4 HIGHWAY structures designed to Eurocodes may be assessed using Eurocodes shall be used as the basis for the design of the following modification works: Strengthening or upgrading works design. Structural element replacement design. Component replacement design in conjunction with the relevant Harmonised Standards (hEN) or European Assessment Documents (EAD) for the component. Other modification Where strengthening or modification of the existing structure involves deriving the resistance, serviceability performance or durability of a section that comprises both new and existing materials acting together, the designer shall make a statement in the AIP to justify the use of Eurocodes in this situation.

5 Taking into account the properties of the existing materials and workmanship compared to those required by the relevant European Standards upon which the relevant Eurocodes Where modification works fall outside the scope of the relevant Eurocodes but where the use of Eurocodes are proposed, the designer shall make a statement in the AIP to justify the use of Where it is not possible to demonstrate the adequacy of a structural element using Eurocodes, assessment standards may be used to re-examine particular elements/load effects for which failure is determined. See also Clause Eurocodes shall be used in conjunction with any relevant Harmonised Standards (hEN) or European Assessment Documents (EAD) for the component for the design of proprietary structures, temporary structures and temporary The Application Rules given in the Eurocodes may not fully cover the design of special types of structures such as moveable bridges or bridges carrying both road and rail/light rail traffic.

6 For such structures additional design rules including values of partial factors, combination factors and values and configurations 1/2 November 2016 Chapter 1 IntroductionVolume 1 Section 3 Part 19 BD 100/16of actions shall be determined for the individual project, in accordance with the relevant Principles given in BS EN Eurocodes may be applied to the design of structures where materials used and / or the actions applied are outside the scope of Eurocodes. See also Clauses & Eurocodes shall not be used in combination with UK National Standards (Non-Eurocodes).
