Introduction
Transitional Arrangements
This document applies to works, or buildings in which material changes of use takes place, where the works or the change of use commence or take place, as the case may be, on or after 1 July 2013. Technical Guidance Document A - Structure, dated 1997 also ceases to have effect from that date.
The Guidance
The materials, methods of construction, standards and other specifications (including technical specifications) which are referred to in this document are those which are likely to be suitable for the purposes of the Regulations. Where works are carried out in accordance with the guidance in this Document, this will, prima facie, indicate compliance with Part A of the Second Schedule to the Building Regulations.
Existing Buildings
In the case of material alterations or changes of use of existing buildings, the adoption without modification of the guidance in this document may not, in all circumstances, be appropriate. In particular, the adherence to guidance, intended for application to new work may be unduly restrictive or impracticable.
Technical Specifications
Building Regulations are made for specific purposes, e.g. to provide, in relation to buildings, for the health, safety and welfare of persons, the conservation of energy and access for people with disabilities. Technical specifications (including harmonised European Standards, European Technical Approvals, National Standards and Agrément Certificates) are relevant to the extent that they relate to these considerations. Any reference to a technical specification is a reference to so much of the specification as is relevant in the context in which it arises. Technical specifications may also address other aspects not covered by the Regulations.
A reference to a technical specification is to the latest edition (including any amendments, supplements or addenda) current at the date of publication of this Technical Guidance Document. However, if this version of the technical specification is subsequently revised or updated by the issuing body, the new version may be used as a source of guidance provided that it continues to address the relevant requirements of the Regulations.
A list of other standards and publications that deal with matters relating to this Part of the Building Regulations is included at the end of this document. These standards and publications may be used as a source of further information but do not form part of the guidance.
Materials and Workmanship
Under Part D of the Second Schedule to the Building Regulations, building work to which the Regulations apply must be carried out with proper materials and in a workmanlike manner. Guidance in relation to compliance with Part D is contained in Technical Guidance Document D.
Interpretation
In this document, a reference to a section, sub- section, part, paragraph or diagram is, unless otherwise stated, a reference to a section, sub- section, part, paragraph or diagram, as the case may be, of this document.
