What should the geotechnical profession know about the changes in the Code?

The Code gives references to parties their functions and responsibilities to using the code. An example is the Classifier and Qualified Engineer. Reference is made to role of Engineering Geologists and Geotechnical Engineers.

To understand the responsibilities of the qualified engineers using the code, the objective of the Code is needed to be understood and its relevant contents. A review will be made of the Scope, Site Classification, example of a Site Investigation for a Classification, estimation of the Characteristic Surface Movement, excavations and filling, Site Investigation requirements, Design by Engineering Principles, requirements in Aggressive soils, Deep footings requiring Geotechnical Site Investigations, Driven Piles, Screw Piles and a Guide to Design of Footings for trees.
