Correspondence. ‘ A Twenty-storey Office Block Founded on Soft Sand in Nigeria ’ by A. S. Grimes and W. G. Cantlay, Published in The Structural Engineer, February 1965

Mr. D. R. Narahari and Mr. V. S. Aggarwal (Central Building Research Institute, Roorkee, UP, India) writes:- ‘The authors’ Figs 11 and 12 show dissimilar features for the static and dynamic cone tests on the compacted soils. After about 13 ft the static cone results are at variance with the results of dynamic cone tests. The static cone value starts decreasing after about 13 to 15 ft. At 20 ft the value is nearly the same as in the uncompacted state.'
