Sanofi Pasteur, the vaccines division of Sanofi-Aventis Group, is the largest company in the world devoted entirely to human vaccines. The company currently has approximately 1500 employees at the Sanofi Pasteur Toronto campus. The campus sits on the original 44 acre site, which includes approximately 40 buildings with staff parking at the perimeter, creating a very pedestrian friendly walkable campus.

Over the years, infrastructure legacy issues have resulted in very limited space for new and current infrastructure. A typical internal roadway has a storm sewer, 2 sanitary sewers, a watermain, 1 to 2 concrete encased electrical banks, steam and condensate lines, gas main, fibre optics and many abandoned bits and pieces.

Burnside worked with the Sanofi Pasteur Engineering and Environmental Health and Safety groups to replace the old failing infrastructure and to provide the site with a clean bill of health. Over the span of 2 years, Burnside provided environmental, land development, water and wastewater and electrical and mechanical engineering, as well as field services to the firm.

Burnside discussed the possibility of a GIS based asset manager to assist them in forecasting infrastructure and budget needs (a solution initially developed for institutional and municipal purposes). Burnside provided a Stormwater Management Master Plan, a Functional Servicing Report and an Environmental Impact Statement (EIS) to retrofit the 20 ha site to current standards.

Project Specifics Included:

• Design and construction administration of a trunk storm sewer system
• 3 of the largest oil grit separators made
• 2000 m³ underground stormwater storage system that will allow for future construction staging above
• Sanitary sewer twinning for increased capacity
• Watermain upgrades for old sections
• Reconstruction of several internal roads
• Servicing design and construction administration
• External servicing of 4 new buildings on site
• Environmental assessment and characterization through a comprehensive Phase I and a number of Phase II Environmental Site Assessments

Burnside developed a remediation process for some legacy contamination issues on a small portion of the property and the replacement of 4 underground storage tanks (UST) with 2 new double-walled USTs and a large above ground diesel tank for back up fuel to their onsite emergency co-generator system.
