Standard Guide for Dimensional Coordination of Rectilinear Building Parts and Systems

1.1 This guide covers the application of dimensional coordination in building design and the fabrication of rectilinear building parts and systems. A minimum number of preferred dimensions are recommended to give a range of alternatives that should result in economies in design, detailing, production, and construction. Dimensional coordination should be used where benefits in documentation, fabrication, installation, and maintenance can be established, but is not intended to eliminate uncoordinated custom design.

1.2 Specifically, the guide covers:

1.2.1 Descriptions of terms used in dimensional coordination.

1.2.2 The basis for the dimensional coordination of building parts and systems in the design of buildings.

1.2.3 Preferred horizontal and vertical dimensions for building parts and for the coordination of systems.

1.3 This guide does not state preferred dimensions and sizes for building components, except for general principles.

1.4 Basic guidelines for dimensioning in modular drawing practice are given.

1.5 Where practicable, recommendations in international standards prepared by the International Organization for Standardization (ISO) have been taken into account.
