The current NBC 2010 is the 13 th edition. - First edition of the ABC in 1974 revised in 1977 and has subsequently published new versions about every five years. The current ABC 2014 is the 9 th edition. - First edition of the National Fire Code Fire Code in The Associate Committees on the National Building and Fire Code, were replace in 1991 replaced by the Canadian Commission on Building and Fire Codes (CCBFC)

5 HISTORY OF BUILDING CODE IN ALBERTA The Present Changes to the Safety Codes Act The legislation brings about a n umber of key changes including:: **Timely adoption of codes and standards, Administration of the Safety Codes Act, Administrative penalties, and Municipal bylaw making authority **The Alberta Permit regulation amended March 31, 2015 and brought the 2014 ABC into force for May 1 st 2015.

36 Soil Gases Radon is a colourless, odourless, radioactive gas that occurs naturally as a result of the decay of radium known to enter dwelling units and buildings by infiltration into basements and crawl spaces. Health Canada estimates 1900 lung cancer death per year are related to radon. We spend more time indoors, including basements. Tighter buildings Some geographical areas are known for high risk of radon in the ground. Heath Canada reduced the Canadian action level from 800 Bq/m3 to 200 Bq/m3 (international standard)

Part 9 Buildings Subsection Soil Gas Control (2)(3) --Soil Gas Ingress (2)(c)iii & (3)(b)iii Subfloor Depressurization system (8) -- protection against depressurization-- Radon

40 Radon Providing for the Rough-in for a Subfloor Depressurization System a) a gas-permeable layer, an inlet and an outlet as described in Sentence (2), or b) clean granular material and a pipe as described in Sentence (3). Sentence (2) describes the criteria for subfloor depressurization systems using performance-oriented language, while Sentence (3) describes one particular acceptable solution using more prescriptive language.

41 Radon Providing for the Rough-in for a Subfloor Depressurization System b) clean granular material and a pipe as described in Sentence (3).

42 Radon The principal method of resisting the ingress of all soil gases, a resistance which is required for all buildings, is to seal the interface between the soil and the occupied space, so far as is reasonably practicable. Sections and contain requirements for air and soil gas barriers in assemblies in contact with ground, including those in crawl spaces. Providing control joints to reduce cracking of foundation walls and airtight covers for sump pits (see Section 9.14.) are other measures that can help achieve this objective.
