Question: You are the contractor for a dwelling where no geotechnical report has been prepared and presumptive load-bearing values are being used.

This requirement is triggered where the likely allowable bearing capacity is less than what value?

- B. 3,000 pounds per square foot
- C. 2,000 pounds per square foot
- D. 1,000 pounds per square foot
Correct Answer: A
Footnote b to IRC Table R401.4.1 states that where the building official determines that in-place soils with an allowable bearing capacity of less than 1,500 psf are likely to be present at the site, the allowable bearing capacity shall be determined by a soils investigation.
