Geotechnical Investigation and Design for Foundation Engineering Works
Dr Chris Haberfield
For years geotechnical practitioners have commented on the failure of clients to appreciate the value of good site investigation and the benefits of obtaining more detailed information. Some of the benefits of a good ground investigation coupled with appropriate experience, analysis and design in foundation engineering projects are potential savings in construction costs, potential for assessment of foundation alternatives and reduction of risk in ground works. The savings can be significant – of the order of hundreds of thousands if not millions of dollars for the larger projects. Why then do clients seek to “save” money with taking on the lowest price ground investigation?
This presentation provides a guide to both structural and geotechnical engineers about the various levels of ground investigation, analysis and design which are available and through the use of case histories, illustrates the significant benefits that higher levels of sophistication can bring to the project.
