Custom screed at Waikanae

The Brian Perry Civil team at the Waikanae water treatment plant is making strides in enhancing the facility's seismic resilience, including the construction of a water clarifier tank. Faced with the challenge of completing the concrete placement for the massive tank floor to strict level tolerances and the required finish within just six hours, concrete placing companies were hesitant to take on the task.

Project Engineer Jacob Walmsley and Supervisor Jethro Staite devised an innovative solution by customizing a vibrating screed to fit the size and complexity of their operation. Project Manager Daniel Doyle praised the team's ingenuity, noting that while vibrating screeds are common, their tailored version allowed the BPC site team to self-perform the work seamlessly.

This custom screed not only saved considerable time and labour but also eliminated the need for concrete workers to manually screed while standing in the pour. The team plans to apply these lessons learned to future large-diameter tank base pours.
