Common arrangement of work sections for building works

The purpose of the Common Arrangement of Work Sections (CAWS) is to define an efficient and generally acceptable arrangement for specifications and bills of quantities for building projects. It consists of a set of detailed work section definitions, all within a classification framework of Groups and Sub-groups. The CAWS classification down to the level of work section titles forms one of the fifteen tables of the Uniclass classification scheme.

The detailed work section definitions form the largest and most important part of this document. Different titles often mean different things in different industry documents and to different groups of people. The detailed definitions are provided in order to reduce needless variations and conflicts between documents and even within the same document. In practice this means concentrating on the boundaries to ensure that gaps and overlaps between sections are eliminated.

CAWS includes about 360 work sections. They are derived from close observation of current practice, following the pattern of sub-contracting in the industry.

The primary factors which influence and define these work groupings are:

  • Responsibility for design and performance
  • Methods of working, related to sub-contract practice.

The 360 sections vary widely in their scope and nature, reflecting the large range of building materials, products, systems, specialists and sub-contractors which now exist.

Common arrangement of work sections for building works is available from RIBA Bookshops.
