For the last few years, the OAA has made a package of 10 CSA standards, referenced in the Ontario Building Code (OBC), available to its members for free
. Architects should be aware that the selection of available standards is being changed. As of May 1, the following standards will no longer be available through the OAA program:
- A123.1/A123.5, Asphalt Shingles Made From Organic Felt and Surfaced With Mineral Granules / Asphalt Shingles Made From Glass Felt and Surfaced with Mineral Granules;
- A179-2014, Mortar and Grout for Unit Masonry;
- A23.1/A23.2-2014, Concrete Materials and Methods of Concrete Construction / Test Methods and Standard Practices for Concrete;
- A23.3-2014, Design of Concrete Structures; and
- O86-2014, Engineering Design in Wood.
In their place, architects using the OAA program will be able to access the following:
- S304.1-14, Design of Masonry Structures (includes Update No 1 );
- CAN/CSA-A165.1-04 and CAN/CSA-A165 Series-14-2014, Concrete Block Masonry Units (consists of A165.1, A165.2, and A165.3);
- S413-14, Parking Structures;
- CAN/CSA-O325-16 R.2016, Construction Sheathing; and
- CAN/CSA-F326-M91-2014, Residential Mechanical Ventilation Systems.
Access to these five standards continues:
- A371-2014, Masonry Construction for Buildings;
- A440.4-2007, Window, Door, and Skylight Installation;
- AAMA/WDMA/CSA 101/I.S.2/A440-2011, North American Fenestration Standard/Specification for Windows, Doors, and Skylights (NAFS);
- S478-1995, Guideline on Durability in Buildings; and
- B651-2012, Accessible Design for the Built Environment.
As before, members will have access to the latest versions of the standards as well as to the previous versions where available.
