Muskrat Falls, Labrador, Canada Construction work: Astaldi Canada Type of structure: Hydro power plant Facts: taking into account the most stringent environmental conditions, LEED certified for sustainable construction Construction time: 2014 – 2017
The 824-MW hydraulic power plant at Muskrat Falls in Canada consists of a turbine building with four turbines, three dam constructions, six spillway piers, dividing and supporting walls and northern and southern operating areas. It is the second-largest hydraulic power plant in Canada. Temperatures that fall to –40°C are not infrequent on site and represent a huge challenge for construction work. Doka provided a project-specific formwork solution and set new standards for the measurement of concrete strength with the innovative Concremote system.
Products used: Large-area formwork Top 50, Column formwork Top 50, Dam formwork D22, Load-bearing tower Staxo 100, Framed formwork Framax Xlife, Formwork planning, Formwork Instructor, pre-assembly, Concremote
Challenge: • temperatures as low as -40 °C and constantly changing weather conditions • due to project size – on-site storage and assembly of formwork on-site subject to restrictions • customized shape of outer turbine walls demand that concrete and steel joins seamlessly • working safely and quickly
Project solution: • individually adaptable formwork solutions for different weather conditions that were heated as needed. This made adherence to the construction schedule feasible. • use of only one load-bearing system on the site thanks to the universal usability of the Load-bearing tower Staxo 100. It is made for economical shoring of thin as well as 4 m thick floors of the powerhouse. • ladder systems such as stair towers and ladders built into the formwork solutions guarantee safe accessroutes. • Concrete strength measurement with Concremote is made for exact monitoring of hydration heat development. Stripping times, treatment times and the time for pre-stressing are derived online directly from the measured values. This allows a construction process that is safe and fast. • pre-assembled platforms and formwork panels supplied by Doka's Toronto branch resulted in accelerating the construction workflow and reducing on-site personnel costs • just-in-time deliveries permitted responding even to workflow changes with short notice • special formwork for outside walls of the turbines so that steel liner could be affixed without any problems
