Cost-Effective Underground Solutions -- Representing Taggart Quality

Taggart Construction’s competence in underground construction stands heads above the competition -- and its five decades of successful projects prove it.

Transitway

The Region’s transitway is a centerpiece project which illustrates the firm’s versatility and skill. One large depressed section, in particular, required rock cuts seven metres deep. The undertaking also showcases the firm’s productive alliance with Doran Contractors, which built many transitway stations.

Sewers and Water Mains

In a typical challenge, Taggart Construction surmounted the difficulties and the risks of placing five pipes under the Rideau River during severe winter conditions. Working from barges, the firm excavated the trench and used divers to install a water main and sanitary sewers. The project was a huge success - completed safely and ahead of schedule while maintaining rigorous environmental standards.

Municipal Works

For the Acres Road pumping station, Taggart Construction employed a creative technique to deal with unstable soil below the water table - successfully eliminating the cost and risks of shoring. Sinking a succession of concrete rings to form caissons, the firm was able to construct a wet well with a depth and width of 20 metres - one of the largest in Canada.

Roads

In west Ottawa, Taggart Construction brought cost-efficient solutions to the complicated problems of building a road be for Highway 416 under railway tracks. Excavation in sensitive leda clay was accomplished after undertaking the installation of an extensive system of cement/bentonite cut-off walls and reinforced concrete diaphragm walls, supported by numerous rock anchor tie-backs, using tremie-placed concrete slurry wall techniques. Pre-stressed, pre-cast concrete panels provide an architectural finish to the completed retaining walls.
