The Portland Cement Association (PCA) is revising its standard called PCA100, Prescriptive Design of Exterior Concrete Walls for One- and Two-Family Dwellings. Provisions of PCA100 apply to the design and construction of concrete footings, foundation walls and above-grade walls, both load bearing and non-load bearing, intended primarily for use in detached one- and two-family dwellings. PCA100-2017 is based on the 2014 edition of the American Concrete Institute Building Code Requirements for Structural Concrete and the 2015 International Residential Code.

PCA’s American National Standards Institute approved procedures require that consensus standards like PCA100 be subject to public comment. The public review draft of PCA100-2017 is available and the comment period will close on November 2, 2017. Following the review period, the update committee will address comments. The updated standard is anticipated to be published by December 31, 2017.
