The Deep Foundations Institute (DFI) and European Federation of Foundation Contractors have launched a survey of bored piling techniques in order to look at differences in techniques used in Europe and the US.
Analysis of the results is expected to be delivered at the DFI annual conference in Atlanta, US in October this year and it is hoped the results will highlight best practice.
According to DFI drilled shafts/bored pile best practices chair Alan Macnab, the survey deadline has been extended to try and get additional information from the European market. He said that the study, which can be undertaken anonymously, will look at design, construction, quality assurance and controls, contracting methods, and analysis/inspection tools.
The deadline for responses is 15 March. The online survey is hosted here: http://survey.constantcontact.com/survey/a07e8fsk2cthndezmrx/start
