Geological Consulting has supported Stantec on several New Zealand dam safety projects. They have provided desktop studies and site investigations; where a good understanding of the local geology, dam and foundation materials, instrumentation, and wider dam safety issues including flooding, internal erosion and seismicity has been required. They have consistently exceeded expectations in terms of technical delivery, programme, safety, and end-client satisfaction.

Project
Meander Dam – 20-year Dam Safety Review
Client: Tasmanian Irrigation
Location: Tasmania, Australia
Date: 2025
Geological Consulting was commissioned by Tasmanian Irrigation to conduct an independent technical review of the geological aspects of the Meander Dam Safety Review (DSR). Meander Dam was constructed between 2005 and 2007 and is located 5 km south of the township of Meander, on the Meander River. The dam is a 50 m-high Roller-Compacted Concrete (RCC) gravity dam with a reservoir capacity of 43,000 ML at Full Supply Level (FSL). The dam impounds Lake Huntsman, with water used for irrigation and hydroelectric generation. The dam has been assigned an Extreme Consequence Category (CC) for ‘Sunny Day’ and a High A for ‘Flood Failure’ in accordance with ANCOLD (2012).
