Guide to accuracy in building

Executive summary

Guidance and principles that relate to accuracy in building construction.


This British Standard guide explains and provides examples of principles that relate to accuracy in building construction.

It is intended to be applied to building rather than civil engineering works and aims to assist in the following:

a) avoiding or resolving problems of inaccuracy or fit by assessing the dimensional needs of a design regarding tolerances, and then designing and specifying appropriately;

b) assessing the likely achievement of tolerances specified for a particular project, and giving guidance on their realization; and

c) monitoring and controlling work during construction to ensure that it complies with

specified accuracy.

Appendices to this standard give information relating to site surveys, examples of the calculation of tolerances, characteristic accuracy values, and data from a BRE survey.

This standard is designed to be relevant to all building types including the most sophisticated ones. It is particularly applicable wherever components, made off site, are to be assembled on site with site constructed work, or where statutory maximum or minimum sizes are required.
