The coordination of the building components of educational facilities is discussed. The resulting components will be used for a wide range of building types in addition to schools and the recommendation should therefore be seen as part of a widespread move toward establishing a national British 'pool' of dimensionally related components. The two main objectives presented are--(1) to identify those characteristics which must be standardized if components are to be shared by many users, and establish these standards, and (2) to suggest conventions of assembly for these components. The discussions of the performance standards, and design and manufacture of components and the selection and assembly of components aid in explaining the application of coordinated building components to the construction process.
