Practice Tip PT.3 is re-issued to introduce new tools for use by members in compiling a building code data matrix and includes information on some improvements to the matrices.
Regulation 27 of the Architects Act requires that members must include building code compliance data in an application for building permit in accordance with original Practice Bulletin A.9 2004. PT.3 is an update of the original Practice Bulletin A.9. Appropriate practice in regard to communication of code related data when applying for a building permit includes a systematic approach to compilation and presentation of a summary of the project’s building code compliance data.
This practice tip provides a suggested means of organizing, summarizing and presenting critical building code compliance data that forms the basis for the design of the building.
The summary is not intended to be a comprehensive listing of all items in a building code review or analysis, but rather identifies key building code requirements to which the design complies.
Locating this summary information in a conspicuous place on one of the first sheets of the drawing set not only expedites the building official’s review of the application, but also informs others involved with the project (e.g. contractors, trades, consultants, etc.) about applicable code related issues. Although the information specifically refers to the Ontario Building Code, similar procedures can be used for projects governed by the National Building Code of Canada or any of the other provincial building codes.
New matrix tools have been developed using spreadsheet software (Microsoft Excel) for members' use.
The Excel matrix tool makes extensive use of drop-down lists to speed data entry and to make input more convenient and consistent.
The Microsoft Word based version of the matrices has been retained and updated for those who prefer to use that option.
A new matrix has been developed for Part 10 – Change of Use.
Additional basic information for a building has been included in the matrices for Part 10 and for Part 11.
Energy Compliance for Part 9 buildings is considerably expanded.
The templates are now separated into four individual matrices. One each for: Part 3, Part 9, Part 10, and Part 11 - in order to account for the differences in information included.
The area to include ULC design numbers for horizontal or supporting assembly ratings has been removed since typically several different ULC designations are required and the information is impractical to indicate properly except on the drawings.
The presentation of the Seismic Hazard Index has been simplified from the original introduction in PT.35.
Updates throughout the various matrix templates include the indication of the version of the building code, super-imposed occupancies, energy compliance and other minor adjustments.
In the Excel templates there is a Read Me First tab containing information about working with the Excel workbook. In the workbook there is additional information on supporting tabs to assist in interpolating the limiting distances and the seismic hazard index.
