Specification of Permanent Wood Foundations for Housing and Small Buildings
Also Known As:
The CSA S406-16 (R2021) standard is the fourth edition of the standard. This edition has been revised to reflect changes in the National Building Code of Canada, 2015 and the 2014 edition of CSA O86, Engineering Design in Wood.
Significant changes in this edition include the modification of tables and figures to reflect new load combinations, the correction of terminology from preserved wood foundations to permanent wood foundations, the addition of more details to concrete footings supporting walls and columns, and the revision of requirements for high wind and seismic forces.
The scope of the standard applies to the selection of materials, fabrication, and installation of permanent wood foundations. It specifically provides details for buildings up to three storeys in height above the foundation and with a building area not exceeding 600 m2. The standard also allows for the optional use of wood sleeper, poured concrete slab, and suspended wood basement floor systems as components of the permanent wood foundation, as well as the use of permanent wood foundations enclosing crawl spaces.
The standard uses SI (metric) units as the standard, with values given in parentheses for informational purposes. It also notes that nails are commonly identified by their length in inches, while lumber sizes are expressed in terms of thickness x width, with metric values referring to standard dry dressed sizes and imperial values referring to nominal nondressed sizes in conformance with CSA O141.
