A number of our team members are currently seconded to the North Canterbury Transport Infrastructure Recovery (NCTIR) project, providing geotechnical services for the earthquake recovery works north of Kaikoura. Within NCTIR our people sit in the coastal structures design team and have played an important role in the reconstruction and realignment works of State Highway 1 (SH1). They are an integral part of the design team responsible for approximately 2.5 km of new seawalls that range from 3 to 10 m in height. The innovative seawall design comprises Mechanically Stabilised Earth Walls (MSEWs) with mass concrete block facing units. The mass concrete facing blocks were designed and produced in-house, specifically for the project and include a bespoke design for the connection between the blocks and the MSEW. Full scale field trials of the connection detail were undertaken to ensure all design assumptions were met, and to assess the stress-strain characteristics and performance of the connection. The analysis and design methodology employed for the seawalls was innovative, following a performance based design approach and was modelled utilising Finite Difference, Stress-Strain analysis techniques.

In the residential space, the team has continued to provide expert advice and support to our insurance Clients working through some tricky projects and legal cases, along with continued support to our range of existing clients including builders, main contractors and private homeowners.
