CHEVIOT MINE

Owner: Fording River Coal Corp.

Formula installed three (3) Structural Plate Super-Cor Arches at the new Cheviot Mine Haul Road located South of Hinton AB.  The largest structure was the Whitehorse Crossing which required an H-Pile foundation consisting of 6500 Lineal Meters of driven piles.  A cast-in-place cap foundation was built to support the double skinned arch.  The structural fill over the pipe assembly required a mesh Visit-A-Wall MSE System to retain 50,000 Cubic Meters of fill at each end both upstream and downstream.  The two other constructed arch structures were completed for commercial and recreational traffic and to provide access under the main haul road.
