Q1/ A five story office building are to be built in a deep, high quality fine-grained soil deposit. The bedrock has a depth of over 75 m. The foundation level will be located at a depth of 1 m below ground surface. At the foundation level, the unfactored uniformly distributed load (q) from the building structure is 70 kPa. The building will be 50 m wide and 85 m long. Estimate: (a) The required number, spacing and location of exploratory boreholes. (b) The required depth of the boreholes by a) Aop = 0.10 q and from Table 2, find the minimum depth.

Q1/ A five story office building are to be built in a deep, high quality fine-grained soil
deposit. The bedrock has a depth of over 75 m. The foundation level will be located at a
depth of 1 m below ground surface. At the foundation level, the unfactored uniformly
distributed load (q) from the building structure is 70 kPa. The building will be 50 m wide
and 85 m long. Estimate:
(a) The required number, spacing and location of exploratory boreholes.
(b) The required depth of the boreholes by a) AoD = 0.10 q and from Table 2, find the
minimum depth.
