Table 4.2.1.1 is based on the following assumptions:

The design is applicable to all seismic zones.
The maximum building width is 12.2 m.
The maximum building length is 24.4 m.
The maximum floor clear span is 6.1 m.
The maximum roof clear span is 12.2 m with supports at mid-point.
The maximum number of stories above grade is two (2).
The maximum number of stories below grade is one (1).
The roof slope from flat to maximum 1:1.
The roof dead load is 0.72 kPa.
The floor dead load is 1.2 kPa.
The floor live load is 1.92 kPa.
The snow load is 4.44 kPa.
The surcharge load is 2.4 kPa.
The loads include earth pressure and surcharge loads, plus gravity load. The gravity load assumes two (2) ICF storeys and a wood roof frame.
Below-grade walls are assumed to support a brick veneer with a maximum height of 7 320 mm, with an eccentricity of 220 mm for the 150-mm-thick wall system and 245 mm for the 200-mm-thick wall system.
The design earth pressure is 960 kg/m³ (equivalent fluid density).
All above-grade walls are assumed to be on top of the ICF foundation walls.
Openings in the foundation wall must be less than 1 220 mm in width, and the total openings in the wall must be less than 25% of the wall area.
When the length of the wall between windows is less than the average length of the windows, the wall is considered to be unsupported and additional engineering is required.
Reinforcing bars must be hard-grade deformed bars conforming to CSA G30.18-09, "Carbon Steel Bars for Concrete Reinforcement," Grade 400. The specified yield strength of reinforcement, f_y, is 400 MPa.
Wall designs that detail bends, placement, spacing, splicing, and protection of reinforcement must be in accordance with CSA A23.3-14, "Design of Concrete Structures."
The minimum concrete cover for vertical reinforcement is 35 mm from the inside face (tension face) of concrete.
The minimum concrete cover for horizontal reinforcement is 25 mm from the inside face of concrete.
Two 10M bars must be placed around all openings and extend 600 mm (24 in) beyond each side of the openings.
There shall be a minimum 28-day concrete yield strength of 20 MPa. Mix designs in accordance with the manufacturer's recommendations.
There shall be a minimum 4% to 7% concrete air entrainment when exposed to freeze/thaw cycles.
The concrete must be allowed to cure for a minimum of seven (7) days prior to backfilling.
Below-grade walls must be supported by the floor system at the top.
All materials and workmanship must conform to the requirements of the NBC 2015, including any Revisions and Errata that have been released as of the issue date of this table.

Table 4.2.1.2 is based on the following assumptions:

The design is applicable to seismic zones up to S_a(0.2) = 1.2 for Site Class C.
Applicable to a maximum wind pressure of q(1/50) = 1.2 kPa.
For allowable building dimensions and floor and roof clear spans, see Note (1) to Table 4.2.1.1.
For assumed loads, see Note (1) to Table 4.2.1.1.
For concrete and steel material properties, see Note (1) to Table 4.2.1.1.
Above-grade vertical reinforcement is to be placed in the middle third of the wall section.
Above-grade horizontal reinforcement is to be placed in the middle third of the wall section.
A minimum of two 10M bars should be placed around all openings and must extend at least 600 mm beyond each corner of the opening.

Notes:

Footnote 1

Tables 4.2.1.3(a) to 4.2.1.3(f) are based on the following assumptions:

The factored uniformly distributed load includes live and dead loads, not including the weight of the lintel.
The minimum height of the lintel is 210 mm for Tables 4.2.1.3(a) and (d); 419 mm for Tables 4.2.1.3(b) and (e); and 629 mm for Tables 4.2.1.3(c) and (f).
Stirrups are single-leg fabricated from 10M bars spaced at 100 mm on centre (o.c.) for Tables 4.2.1.3(a) and (d); 200 mm o.c. for Tables 4.2.1.3(b) and (e); and 300 mm o.c. for Tables 4.2.1.3(c) and (f).
Lintel reinforcing is located at the bottom of the lintel and projects 320 mm for 15M bars and 430 mm for 20M bars into the lintel support on each side.
The specified compressive strength of concrete, @ 28 days f'_c, is 20 MPa.
The specified yield strength of reinforcement, f_y, is 400 MPa.
A minimum of two (2) 10M bars must be placed around all openings and must extend at least 600 mm beyond each corner of the opening.
