HISTORY OF BUILDING CODE IN ALBERTA
PAST, PRESENT, FUTURE…
Evolution of the code development system
Past - First edition of the NBC in 1941 , revised in 1953 and has subsequently
published new versions about every five years. The current NBC 2010 is the 13th
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 9th edition.
- First edition of the National Fire Code Fire Code in 1963
- 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)
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 1st 2015.

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)

Sentence (3).
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 9.18.
and 9.25. 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.

Treatment means the provision of
medical or other health-related
intervention to persons, where the
administration or lack of administration
of these interventions may render them

management to residents who require these
services because of cognitive, physical or
behavioural limitations.
Care Occupancy
Care Occupancy
Through care facility management refer
to services provided by the
organization that is responsible for the
