BRIDGE PROJECTS

When the Alberta Government decided to contract out routine repair and maintenance of bridges in 1996, Carmacks was ready to move in and made bridge activities a core business. Because of the specialized nature of the work requiring specific skills and abilities, Carmacks sought out ex-government employees with the training and experience specific to the business and employed them to provide these services.

FEATURED PROJECTS

October – November, 2009

The Special Areas is a rural municipality in Southeastern Alberta. Under the Special Areas Act, the Special Areas Board is responsible for the administration of approximately 2.6 million acres of public land within the area. These lands consist of 1.6 million acres of Crown land and one million acres of Tax Recovery land. The Special Areas Board leases these lands to local farmers and ranchers for grazing and cultivation purposes.

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.

June 2008 – June 2009

The Nigel Creek Bridge Rehabilitation Project involved numerous repair items including removal of the existing ACP wearing surface on the bridge deck and approach roadways, expansion deck joint replacement, drainage modifications, application of a waterproofing membrane, repaving with hot mix ACP, bridge rail repairs, approach guardrail replacement, clean and metalize bearings, partial and full depth concrete repairs to various bridge elements, and clean and seal concrete.

January – June, 2009

The general scope of work for this project was to replace the existing bridge while maintaining a single lane, two-way traffic during construction. The work involved the demolition of the existing structure and constructing a new three span SCC Composite bridge and roadwork.

February – September, 2010

The general scope of work for this project was to construct three new bridges on a new roadway alignment. The work involved driving piles, cast in-place concrete abutments, erection of precast pile caps & girders and cast in-place HPC concrete deck.

January to March, 2010

This project involved the replacement of a bridge carrying Hwy 201 over the Qu’Appelle River east of Regina. The existing bridge was a clear span concrete arch with suspended deck that was replaced by a three span precast girder bridge with ACP (asphalt concrete pavement) wearing surface on precast pile caps, steel pipe piles and treated timber backwalls.

November 2010 – January , 2011

Alberta Transportation tendered these two structures along with 29.123 km of grade construction. The bridges were constructed on a virgin alignment making access a challenge. Carmacks commenced construction of these bridges in November 2010 and substantial construction was completed by December 20, 2010. The bridges were constructed simultaneously in order to minimize mobilization costs and to advance the schedule.

November 2011 – April 2012

Carmacks bid and was awarded four contracts to construct five bridges. The general scope of work for these projects was to demolish and construct new bridges on the existing highway network.

September, 2011 – October, 2013

This project consisted of the installation of a temporary detour to accommodate traffic around the new bridge location and channel realignment. The existing three span major bridge and single span overpass were demolished while maintaining unrestricted traffic flow on Hwy. 55. Hwy 813 was realigned and 50th Street extended.
