Elgin Street Renewal

Taggart Construction Limited

City of Ottawa


Urban Reconstruction

$6.5 Million

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.

Project Highlights

  • Installation of storm and sanitary pipe networks up to 1350mm in diameter at depths up to 7m
  • Protection and monitoring of existing watermains in extremely cold temperatures
  • Working within tight schedule requirements to meet incentive deadlines
  • Requirement to work around delicate and critical underground utilities (e.g. hydro, telecom)
  • Modifying and connecting to existing century old brick sewer networks
  • Navigating tight workspaces with overhead utilities
  • Ensuring the safety of our workers and the public in a busy area

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.
