To assist in the avoidance or resolving of problems of inaccuracy or fit, the assessment of the likely achievement of specified tolerances, and the monitoring and controlling of work during construction to ensure compliance with specified accuracy.

This British Standard guide explains and gives 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:

  1. avoiding or resolving problems of inaccuracy or fit by assessing the dimensional needs of a design regarding tolerances, and then designing and specifying appropriately;
  2. assessing the likely achievement of tolerances specified for a particular project, and giving guidance on their realization;
  3. monitoring and controlling work during construction to ensure that it complies with specified accuracy.

Appendices give information relating to site surveys, examples of the calculation of tolerances, characteristic accuracy values, and data from the BRE survey (see the introduction).

NOTE The titles of the publications referred to in this standard are listed on the inside back cover.
