Standard Guide for Dimensional Coordination of Rectilinear Building Parts and Systems (Withdrawn 2011)
ABSTRACT
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. Dimensional coordination of buildings and rectilinear building parts is based on the application of three related concepts such as modular reference grids of lines or planes to define reference locations in space, controlling dimensions in the horizontal and vertical plane as means of controlling the location of major building elements and rectilinear building parts, and coordinating dimensions for building components to reduce variety of sizes and to promote a better fit within the controlling reference system therefore minimizing wasteful cutting or fitting on site. The reference system for dimensionally coordinated design may consist of: a standard modular grid of dimensions; a multimodular grid of two or three dimensions, which may use different modules in different directions; or, a selected set of reference planes or lines spaced at modular intervals but without the use of a regular grid. The reference system is used in design and detailing decisions to locate building parts that may or may not be shown on working drawings.
SCOPE
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.

INTRODUCTION
The concept of coordinating the dimensions of buildings and building parts with the dimensions of
manufactured components and assemblies by means of a common dimensional factor, or module, was
pioneered in the United States in the 1920s and 1930s. The terms “modular coordination” and
“dimensional coordination” were adopted for the use of the basic building module and preferred
dimensions in building design, production, and construction.
In 1939, the American Standards Association (now ANSI) organized project A62, a cooperative
study of dimensional coordination, resulting in the issue of a series of standards concerning the subject
between 1945 and 1971. Responsibility for the continuation of the work was transferred toASTM and
under the general supervision of Committee E06 on Performance of Building Constructions.
Subcommittee E06.62, Coordination of Dimensions for Building Materials and Systems, has the
specific task to develop standards in this field, including metric versions that use the international
building module of 100 mm.
In 1976, ASTM Committee E06 approved ANSI/ASTM E577 to set voluntary standards for the
dimensional coordination of rectilinear building parts and systems in either metric (SI) or inch-pound
units, using a basic incremental dimension (M) with the value 100 mm in SI units, or 4 in. in
inch-pound units.
Subcommittee E06.62 has now prepared companion standards in acceptable metric and inch-pound
units so that designers wishing to apply the principles of dimensional coordination can select
preferences in line with the measurement system used in their documentation. Except for the
dimensions ascribed to the basic building module and, therefore, its multiples, the companion
standards are identical in text.

2. Terminology
2.1 Definitions of Terms Specific to This Standard:
2.1.1 basic building module (basic module)—a unit dimen-
sion used as the standard increment in the dimensional coor-
dination of buildings and building parts.
2.1.1.1 Discussion—For dimensional coordination in metric
(SI) units, the basic building module has the internationally
agreed value of 100 mm; the basic building module is
designated by the symbol M; for example: 100 mm = 1 M;
1200 mm = 12 M. For dimensional coordination in inch-pound
units, the basic building module has the value of 4 in.; the basic
building module is designated by the symbol M; for example:
4 in. = M;48in.or4ft0in.=12 M.

including joints, or an item of building equipment. Rectilinear
