Excellence in Innovation Award – PCL PCL won the CCA Excellence in Innovation Award for Calgary’s Airport Trail Tunnel, a cast–in-place tunnel struc- ture housing six traffic and two LRT lanes. Starting the de- sign in April 2011, the tunnel was completed in October 2012. The project team was able to meet the schedule due to an innovative approach that maximized the flow rate of the concrete pour without exceeding the pressure limits of the formwork. The pressure exerted by the poured con- crete produces an electrical output signal that is received by the small face of the transducers mounted flush with the inside of the form at pre-determined points, and is transmitted to a portable instrument box that measured and recorded pressure data. The box then converts that signal and communicates the data to a visual display as well as a data log. Onsite personnel monitors the pres- sures as the concrete is being poured and communicates the information to the pouring crew. As pressures ap- proach the limits of the formwork design, crews can be in- formed and the pour-rate can be slowed accordingly. Conversely, the pouring crew can also be informed if the rate of pour can be increased without compromising the integrity of the formwork.
