Event Summary: The Rainy River Tailings Management Area (TMA) in Northern Ontario is uniquely situated above highly plastic, normally consolidated glacial clay soils of variable thickness. Since 2022, SRK has assumed the Engineer of Record (EOR) role for the Rainy River TMA. This involves annual TMA dam raise design, on-site support for construction quality control/assurance, and dam performance monitoring during and post-construction. The TMA is of zoned material construction consisting of clay core dams with chimney and blanket filters and rockfill buttressing, constructed upwards of ~30m in height. The clay foundation soils govern the design and construction of the dams. The design of the TMA requires large upstream and downstream rockfill buttressing combined with extensive monitoring to ensure continued performance is maintained. Instrumentation within the TMA foundation is extensive, including piezometers, slope inclinometers, shape arrays, settlement plates and magnetic extensometers to monitor the site. Both significant displacements (both lateral and vertical) and excess pore water pressures are observed throughout the year in response to additional loading. Monitoring of the instrumentation is a constant effort shared by the owner and EOR. The successful construction and operation of the site has benefited from continuous improvements to the monitoring and reporting system, yearly field investigations, interrogation of the most-probable and unfavourable conditions through numerical modelling, and open communication between EOR and owner/site operations.
