Question

Your client wishes to purchase land that slopes down to a street at 20%. He wants to construct a 100 ft. by 100 ft. building with 40 ft. around the building (140 by 140 ft. total) on a relatively flat pad. He does not want to spend much money on engineering as requests that you develop the site using the IBC. Further, he wants his cut/fill transition site with cut slopes and fill slopes. The soil is considered loess (silt) from a soil map. Provide the following: a. How deep will the lot have to be considering the pad and slopes? Show a sketch. b. The frost zone is 2 ft. deep. What will be the presumptive allowable bearing pressure be for the foundations? c. What will the depth of the foundations be? Explain why (2 reasons). d. Do you think it is appropriate to use the presumptive allowable bearing pressure from the IBC or do you think a geotechnical investigation is required? Explain.

Explanation / Answer

slope is 20% and uniform

hence cut will be 20/100*(140/2) =14 ft with same slope

b)

if we considering typical unit weight of 110 lb/ft3 than approxmita allowable Bearing capacity will be 420 to 450 lb/ft2

c)

foundation should be below frost zone to avoid (1 stress reversial 2)excessive settelment

d)

soil investigation is always batter option
