Frank Channel and Kakisa River Bridge Assessment

Both bridges are critical elements of the highway network in the Northwest Territories.

Associated Engineering conducted a close proximity inspection of both structures using a specialized inspection truck.  Prior to conducting  the inspections, a 3-D finite element model was created to evaluate the load rating based on CAN/CAS-S6-00 and identify any members that may be over-stressed or subject to high fatigue cycles.  This work was then used to optimize the ultrasonic integrity inspections of the truss members.

We prepared a report that provided a Life Cycle Cost summary of the retrofit and replacement options, including total costs to 2053, salvage value, and expected residual life.
