Tolerances and Acceptable Measurements under the ADA - Webinar (Recorded)

ADA Standards are complex, understand the most compliant ways to utilize construction tolerances.

Dimensional tolerances as well as construction and manufacturing tolerances are included within the Americans with Disabilities Act (ADA) and its implementing regulations and standards. The tolerances are frequently misunderstood and misapplied. Knowing when and how the tolerances apply is critical for an accurate ADA evaluation of disabled access issues both on a particular site as well as in litigation. U.S. Department of Justice (DOJ) documents have provided some limited help in interpreting and applying tolerances under the ADA. Federal courts have recognized the significance of tolerances in the context of ADA access litigation and have criticized expert witness opinions for failure to consider construction tolerances. Understanding both dimensional tolerances as well as construction and manufacturing tolerances is critical to evaluating whether or not a particular component complies with the accessibility requirements of the ADA. In this topic, you will develop an understanding of dimensional tolerances, construction and manufacturing tolerances, as well as the express tolerances included in the ADA. The sources available to identify conventional industry tolerances will be reviewed. Measurement tools to be used and methods of measurement, as well as applying tolerances to measurements will also be reviewed.
