2. Mike Turner’s thoughts on issue for discussion at IWM 2003
Accuracy is good when comparisons are made with static tests
Not everyone agrees
Costs are 10 to 15% of a static test and will continue to gain favour

3. Based on recent micropile projects monitored by Applied Geotechnical (rock socketed/ overburden depths up to 20 m), elastic settlements have been greater than “theoretical predictions”
Care needed to ensure elastic deflections do not undermine serviceability of pile
