 9.15.3.4. Basic Footing Widths and Areas 

This Article lists the minimum #footings #widths and areas based on anticipated loads. The footing sizes in NBC Table 9.15.3.4. are based on typical construction consisting of a roof, not more than three storeys, and centre bearing walls or beams. For this reason, NBC Clause 9.15.3.3.(1)(b) stipulates a maximum supported #joist span of 4.9 m (16 ft.).

The prescriptive requirements for #house footings are based on the limitations and assumptions depicted in Figure 9.15.-4, and are intended to deal with the majority of situations encountered.
