Elgin Street Renewal

Taggart Construction partnered with AECON Group to provide a complete replacement of the existing underground sewer and water infrastructure along a 1.2km section of Ottawa’s historic Elgin Street. New sewer networks with diameters up to 1350mm and depths up to 7m were installed, including connections to existing brick sewers and replacement of existing sanitary and water services. The Elgin Street Renewal Project introduced many construction challenges such as contaminated soils, large amounts of above ground and below ground utilities, and regular pedestrian traffic. The nature of working in an urban environment brings unique challenges such as maintaining water and sewer service for all businesses and residences along the 1.2km construction corridor and ensuring that necessary outages were completed during off-peak hours to minimize impact.

The scope of work for this contract consisted of a full replacement of the existing combined sewers and watermain with new combined, storm, sanitary, and watermain networks. This also included new catch basins and trunk sewers to meet the growing demand of Ottawa’s downtown core. No surface works or landscaping were included in this contract.
