ADAAG Manual

MISCELLANEOUS INSTRUCTIONS AND DEFINITIONS

Graphic Conventions [3.1]

Dimensions in ADAAG and this manual are absolute unless noted as a maximum or minimum. ADAAG includes in text and figures the metric equivalent (in millimeters). ADAAG uses rounded-off ("soft") metric conversions in most cases; more precise ("hard") conversions may be incorporated in future revisions of the guidelines.

Dimensional Tolerances [3.2]

ADAAG recognizes conventional industry tolerances for field conditions. This applies to the field work, not the design work. Information on specific tolerances may be available from industry or trade organizations, code groups and building officials, and published references. Recommendation: It is good practice to avoid specifying precisely to the maximum or minimum where possible so that achieved dimensions fall within ADAAG requirements.
