Foreword

This British Standard is published by BSI Standards Limited, under licence from The British Standards Institution.

This British Standard has been prepared by Committee B/549.

BS 5502‑22:2003+A1:2013 supersedes BS 5502‑22:2003, which is withdrawn.

Text introduced or altered by Amendment No. 1 is indicated in the text by tags . Minor editorial changes are not tagged.

BS 5502‑22:2003 was a full revision of the standard and incorporated the following principal changes. BS 5502 was restructured into the following broad subject areas:

— Part 0: Introduction;

— Parts 10 to 19: Reference information and legislation;

— Parts 20 to 39: General design;

— Parts 40 to 59: Livestock buildings;

— Parts 60 to 79: Crop buildings;

— Parts 80 to 99: Ancillary buildings.

More specifically, the general design series comprises:

— Part 20: Code of practice for general design considerations;

— Part 21: Code of practice for selection and use of construction materials;

— Part 22: Code of practice for design, construction and loading;

— Part 23: Code of practice for fire precautions;

— Part 25: Code of practice for services and facilities;

— Part 30: Code of practice for control of infestation;

— Part 31: Code of practice for the management of waste (storage and handling);

— Part 32: Guide to noise attenuation;

— Part 33: Guide to control of odour pollution.

A more detailed description of the new structure of BS 5502 is given in Part 0.

The object of introducing the structure was to allow subject areas to be broadly characterized, and related subject matter, whether in the form of recommendations, guidance or supporting data, to be rationalized and brought together If also allows sufficient flexibility 1o enable BS 5502 to be expanded and developed in a logical way in the future.

For the design and construction of, and the loadings for, agricultural buildings and structure, reference is to be made to the relevant material and loading codes of practice, some of the recommendations contained in these codes have been modified by this Part of BS 0552 for classified agricultural buildings and structure. This Part of BS 5502 also contains special provisions peculiar to agricultural buildings and structure that should be taken into account during their design.

It has been assumed in the drafting of this Part of BS 5502 that the execution of its provisions is entrusted to appropriately qualified and experienced people, for whose guidance it has been prepared.

This publication does not purport to include all the necessary provisions of a contract. Users are responsible for its correct application.

Compliance with a British Standard does not of itself confer immunity from legal obligations.
