PROJECT OWNER: Alberta Transportation
PROJECT LOCATION: Highway 36 over tributary to Iron Creek, South of Killam, AB
PROJECT SCHEDULE: August – September, 2009



The general scope of work for this project was to replace the existing single span bridge while maintaining a single lane, two-way traffic during construction. The work involved demolition of the existing structure and constructing a new 8.0 meter single span SL precast girder bridge with a waterproofing membrane and asphalt concrete wear surface by utilizing staged construction.

The work also consisted of designing, fabricating and installing precast concrete backwall and wingwall panels, the first of this type for an Alberta Transportation bridge project. This work involved completely dewatering the site in which Carmacks was successful in doing so even though a previous attempt by others was unsuccessful.

This site is located within a Ducks Unlimited Project which is considered to be an environmentally sensitive area. Carmacks successfully utilized methods to construct the works within these waters with no adverse effect or impact to the environment.

In addition to the original scope of work, Carmacks was given a substantial amount of additional work which was completed by September 30, well before the original contract completion date of October 15, 2009.

Alberta Transportation and their Consultant were very satisfied with the quality of workmanship and complemented Carmacks on being able to dewater the site in order to construct the works when others failed to do so.
