Heads up: Alberta Municipal Affairs clarifies radon mitigation requirements
Standata bulletin 14-BCB-006 states these requirements need to be applied and understood with reference to Part 6 of the ABC 2014, which requires soil gas mitigation methods to be designed, constructed and installed by a registered engineering professional.
Part 9 of the ABC 2014 requires a rough-in to be installed for a subfloor depressurization system for soil gas mitigation. Part 6 of the ABC 2014 does not prescribe mitigation systems for construction, as the appropriate soil gas mitigation system is at the discretion of the registered engineering professional.
Only through testing after the building is constructed can there be a determination that soil gas mitigation is required, according to the ministry. www.municipalaffairs.gov.ab.ca
