AMETI Panmure Phase 1 Project involves construction of three bridges and a covered box in Auckland Volcanic Field consisting of a thin basalt cover underlain by tuff and Puketoka Formation alluvium. Kaawa Formation “bedrock” is at approximately 40 m depth. The Serviceability Limit State (SLS) has been found to be the critical state for the design of foundations across the site. This paper presents considerations of settlement effects on the bridge piles and shallow foundations. Settlement analysis using PLAXIS is discussed and is compared with monitoring results.
