Part 9 Flashcards
To reinforce part 9 Code
What are the radon concentration limits for buildings in the designated areas of Elliot Lake, Faraday Township, and Hyman Township in Ontario?
Buildings must be designed and constructed so that:
The annual average concentration of radon-222 does not exceed 200 Bq/m³ of air, and The annual average concentration of the short-lived daughters of radon-222 does not exceed 0.02 working levels inside the building.
Additional Info (Optional Context):
This applies specifically to:
City of Elliot Lake (Territorial District of Algoma), Township of Faraday (County of Hastings), Geographic Township of Hyman (Territorial District of Sudbury).
What are the design and construction requirements for buildings located on flood plains according to Section 9.1.1.8.?
Buildings constructed on flood plains must:
Be designed and constructed in accordance with good engineering practice to withstand anticipated vertical and horizontal hydrostatic pressures acting on the structure, and Incorporate floodproofing measures to preserve the integrity of exits and means of egress during times of flooding.
What are the compliance requirements for site-assembled and factory-built buildings under Section 9.1.1.9.?
A manufactured building is deemed to comply with the Code if it meets:
CSA Z240.2.1, “Structural requirements for manufactured homes” (for buildings in sections not wider than 4.88 m), or
CSA A277, “Procedure for certification of prefabricated buildings, modules, and panels”
(Except as provided in Sentence (2) and Sentence 12.2.1.2.(2)).
The Code’s requirements apply to:
Building components designed and constructed outside the place of manufacture, and
Site installation of such buildings.

Under Sentence (4) of Section 9.3.1.1., what are the conditions for flat insulating concrete form (ICF) walls to comply with alternative concrete and reinforcing requirements?
Flat insulating concrete form (ICF) walls must:
Not exceed 2 storeys in building height, Have a maximum floor-to-floor height of 3 m, and Be part of light-frame construction buildings.
Flat insulating concrete form (ICF) walls must:
Not exceed 2 storeys in building height, Have a maximum floor-to-floor height of 3 m, and Be part of light-frame construction buildings.
The concrete and reinforcing must either:
Comply with Part 4, or
Meet the following:
Concrete conforms to CSA A23.1, "Concrete materials and methods of concrete construction," with a maximum aggregate size of 19 mm, and
Reinforcing conforms to CSA G30.18, "Carbon steel bars for concrete reinforcement," with specific requirements.
What are the specific requirements for reinforcing in flat insulating concrete form walls under Sentence (4) of Section 9.3.1.1., if not following Part 4?
The reinforcing must:
Conform to CSA G30.18, "Carbon steel bars for concrete reinforcement," Have a minimum specified yield strength of 400 MPa, and Be lapped a minimum of 450 mm for 10M bars and 650 mm for 15M bars. (See also Articles 9.15.4.5. and 9.20.17.2. to 9.20.17.4.)
What standard must cement meet according to Section 9.3.1 of the Code?
Cement must meet the requirements of CSA A3001, “Cementitious Materials for Use in Concrete.”
What are the requirements for concrete in contact with sulphate soil under Section 9.3.1.3.?
Concrete in contact with sulphate soil, which is deleterious to normal cement, must conform to Clause 4.1.1.6 of CSA A23.1, “Concrete materials and methods of concrete construction.”
What materials and characteristics must aggregates for concrete meet under Section 9.3.1.4.?
Aggregates must:
Consist of sand, gravel, crushed rock, crushed air-cooled blast furnace slag, expanded shale, or expanded clay, Conform to CSA A23.1, "Concrete materials and methods of concrete construction," and Be clean, well-graded, and free of injurious amounts of organic and other deleterious material.
What are the requirements for water used in concrete under Section 9.3.1.5.?
Water must be clean and free of injurious amounts of oil, organic matter, sediment, or any other deleterious material.
What are the minimum compressive strength requirements for unreinforced concrete after 28 days under Section 9.3.1.6.?
Except as provided elsewhere in Part 9, the compressive strength of unreinforced concrete after 28 days must be:
32 MPa for garage floors, carport floors, and all exterior flatwork, 20 MPa for interior floors (other than garages and carports), and 15 MPa for all other applications. (See also Article 9.12.4.1., Sentence 9.15.4.2.(1), and Article 9.18.6.1.)
