Waiau Assessment

During the magnitude 7.8 earthquake in November 2016, the Waiau region sustained widespread land and infrastructure damage. One site which Davis Ogilvie has investigated suffered intense shaking, resulting in severe land cracking, soil movement and distress to the alternative construction dwelling on the site.

A conjoint structural and geotechnical inspection allowed a rapid and accurate assessment of the past and future performance of the building. Unfortunately the testing revealed unstable and low strength soils and the building had both settled and rotated. Recommendations were provided to redevelop on a stable area of the site whilst maintaining much of aesthetic appeal of the formed platform.
