Practice objective / multiple choice question 22 from the 2020 Neco Model Questions Vol1 Geography examination.
An engineering geotechnical investigation shows a compressible clay layer \(5\) m thick with an initial void ratio of \(0.9\) and a compression index \(C_c = 0.35\). The effective vertical stress at the middle of the layer before loading is \(100\) kPa. A new building imposes an additional uniform pressure of \(150\) kPa on the ground surface. Assuming one‑dimensional primary consolidation, calculate the total primary settlement of the clay layer (in metres, to two decimal places).
