It is well known that the adoption of an appropriate construction methodology is critical to quality outcomes for bored piles (drilled shafts). Many case studies have been published documenting quality issues that have arisen due to a range of causes involving ground conditions, ground support, drilling and cleaning techniques, groundwater, concrete properties and concreting methods, amongst other things. Despite the body of published information, pile defects remain common in practice. FSG’s managing director, Dr. Ben Collingwood has over 20 years’ experience in the Australian piling industry and has participated in many hundreds of projects involving bored piles in design, construction, testing, and independent expert roles. More than 70 professionals attended his presentation at Australian Geomechanics Society in Queensland. The intent of the presentation was to provide a consolidated review of typical industry practices and to highlight key areas in which construction quality can be enhanced.
