The Surface of the Earth as a Material of Construction

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.
