Kingsbridge Wind Power Project

 

AIL Builds Solid Foundation For Wind Power Project.

Expanding Canada's wind power capacity is a chief priority for EPCOR, a leading developer of non-regulated power plants in North America. But when it was given final regulatory approval to build a 40 MW wind-farm near Goderich, Ontario, the power development corporation needed the expertise to help it get the project off the ground, literally. The materials that form the bases of the massive individual windmills presented a number of engineering, manufacturing and logistical challenges. A narrow working window and the soil conditions of the site on the eastern shoreline of Lake Huron were significant factors. With its engineering expertise, dependable service and innovative products, AIL was a logical partner for McLean Taylor Construction Limited, the sub-contractor hired to lay the windmill foundations for EPCOR. There were also difficulties in both shipping the oversized loads by truck, as well as those of accessing the site through agricultural lands, and installation issues. AIL's specialists rose to the task.

 

 

Timeline.

From the time of order, it took just 45 days for all of the inner and outer rings to be manufactured and pre-assembled at AIL's plant in Ayr, Ontario. The inner rings were nested safely in the 4300 mm pipe during the 3.5 hour trip to the site by truck, where installation was completed upon arrival.

 

"AIL reacted quickly and efficiently to ensure the ever-changing schedule was met. Assembly of the large Bolt-A-Plate structures would typically take place on site, but AIL was able to assemble these at their plant, making it more efficient for the site personnel to install. This efficiency allowed us to accelerate our schedule."

The AIL Advantage.

The project was designed to be kept on track and on budget by engineering and manufacturing the inner and outer rings (17 of each) that formed the base of each wind turbine at the AIL plant in Ayr. The structures were then pre-assembled and shipped to the site, using trucks with escorts, due to the oversized loads. Access roads through farm lands were built in advance using AIL Corrugated Steel Pipe strong enough to support the weight of the loads. On site, the outer and inner rings were placed and concrete was poured between them. The lifting and placing of the 17 structures was particularly difficult since they had to be lifted into place vertically, but the installation was completed safely and successfully.
