(1) For the plan and the loading shown, determine the primary
consolidation settlement every 2 meters of the compressible layer
under the specified footing (seventh digit of your ID number, if O
analyze F12, use Westergaard if the digit is even, Boussinesq if it is
odd)
(2) Assuming that the primary consolidation settlement obtained
above will be completed in 4 years, estimate the secondary
consolidation settlement that would occur from 4 years to 15 years.
