The aim of any site investigation should be to reveal and quantify the ground conditions which will affect the feasibility, design and performance of the proposed engineering structure. The engineering geologist is largely concerned, therefore, with providing information to the engineer on:
(i) The nature of the materials present at the site (rock, soil and water),
(ii) The distribution of these various materials, in both plan and depth, and
(iii) The likely properties and behaviour of these materials under the set of conditions to be imposed by the construction of the proposed works.
