BS 5606-2022 pdf free download – Accuracy and tolerance in design and construction — Guide.
This British Standard gives guidance on and provides examples of principles that relate to accuracy and tolerance in design and construction activity for the built environment. It is intended to be a practical guide to assist designers and constructors in determining and managing the risks associated with accuracy and tolerance and taking steps to control them appropriately, which, if unmanaged, can be very significant to cost, time and quality. The fundamental objective is to provide awareness and advice on ways to avoid problems of inaccuracy or fit arising on-site.
The need for such advice on any particular project varies, depending on the character of the project and the materials and methods of construction.
This British Standard is designed to be relevant to all types of construction including the most sophisticated ones. Those concerned with an individual project can judge the extent to which each section is relevant to their needs.
This British Standard takes into account the growing importance of off-site construction [e.g. MMC (modern methods of construction)] and the changes in technology (e.g. digital measuring equipment) and processes [e.g. BIM (building information modelling)] since the last edition was issued. However, it also retains previous guidance where it provides essential insight and wisdom which might still be relevant today.
While this British Standard is not a guide to productivity in the construction industry, some of the impacts of accuracy and tolerance on productivity, which can be either potential improvements or lessons to be learnt, have been illustrated in Section 2 by practical examples for user understanding. These are not exhaustive but are intended to highlight how these impacts can be significant, either positive or negative, and that this standard can be used as an important part of the quality planning, management and execution of design and build activity for the built environment (buildings and infrastructure).
This British Standard is designed to support the creation and implementation of a project strategy for accuracy and tolerance and provide practical implementation guidance throughout the life cycle and is supported and supports other important standards and processes. It is intended to be applied to buildings and infrastructure works in design and construction 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 in construction specified for a particular project, and giving guidance on strategies to verify capabilities and mitigate challenges;
c) providing for monitoring and controlling work during construction to check that it is in accordance with specified dimensional tolerance and accuracy for surveys;
d) aiding digital design and engineering (on- and off-site) including the application of BIM for the built environment; and
e) understanding the importance of the accuracy of surveys undertaken pre, during and post construction works to measure existing features and as-built with the ability to support and verify the achievement of design tolerances and fit.

3 Terms and definitions
For the purposes of this British Standard, the terms and definitions given in BS 6100-11 and the following apply.
3.1 building information modelling (BIM)
processes, technologies and skill sets required for the management of information through the whole life cycle of a built asset, from initial design all the way through to construction, operations and maintenance and finally de-commissioning
NOTE BIM is achieved through the definition of information requirements for the organization, asset and project and use of digital technologies for modelling, collaboration and coordination of information and data across multiple disciplines and organizations, which in turn supports quality assurance workflows to enable informed decision making and verify client requirements achievement at each key stage in a project life cycle.BS 5606 pdf download.
