SIR,--I have been eagerly anticipating Mr. Andrews’s paper on the above subject, and your March issue to hand this morning has enabled me to read it with pleasure.
On the 15th January, 1934, the Building Acts Committee of the London County Council
made the following recommendation:-
WHEN a structural engineer designs a foundation, he requires to know the capacity of his subsoil, not only on the surface, or at the date of erection of the superstructure,
but throughout its depth and throughout the period of time during which his structure is expected to last. The properties of the materials he uses above ground and for his
footings are so well known and so standardised both in manufacture and use that few erectors and designers realise the amount of observation, experiment, and control of characteristics on which depends the knowledge that enables them to calculate the amount of steel needed for a floor beam or a bridge member, or the amount of concrete needed for a column.
