Estimated versus measured capacity of CFA piles for Seaford Road bridges, Melbourne

This paper discusses the design of piles for a rail bridge in south east Melbourne which adopted a relatively conventional approach to estimating static axial pile capacity and compares it to construction stage validation. On site validation included assessment of pile installation data provided by the piling rigs on board computer. Some agreement between the interpreted ground profile and the data obtained from the piling rig outputs was observed. The results of fifteen dynamic pile tests and two sacrificial (non-working) pile tests are also presented. These tests demonstrated greater capacity than may be estimated through these conventional approaches. This presents opportunity to further refine pile design on subsequent stages of the project leading to a more robust and cost effective design.
