CCA is pleased to present PCL with the 2015 CCA Excellence in Innovation Award for its innovative thinking which resulted in an effective and cost-saving, yet simple, solution at the Heartland Foundation Substation 12S northeast of Edmonton, Alberta.
PCL’s Edmonton Buildings group worked with subcontractor Agra Foundations to install piles at the substation site. Silty, sandy layers of clay overlying plastic bedrock created optimal conditions for installing cast-in-place bored piles. However, the cold winter weather meant that the traditional method of installing a prefabricated hoarding box over each pile cap, with an indirect heater attached to the box, was less than practical. Instead, PCL used pop-up ice-fishing tents with propane heaters.
The savings associated with the ice-fishing tent innovation were realized in three areas: 1) tents compared to wooden hoarding boxes, 2) heating, and 3) other labour. Overall cost savings using the tent plan as opposed to traditional heating and hoarding was $415.45 per pile, or $166,180 with over 85 per cent of the savings having come from heating. The biggest difference in heating costs was in the amount of propane required by the more efficient sunflower heater housed in an ice-fishing tent, a structure designed to retain warmth.
