Project Overview:

SSWA was retained to complete a noise control study in support of a Site Plan Applications for a high-rise residential development in Mississauga. The study evaluated environmental noise from surrounding transportation corridors and nearby infrastructure, established mitigation requirements to ensure compliance with applicable noise guidelines, and identified practical design strategies to support a comfortable living environment for future residents.

Challenges

The site is influenced by multiple transportation noise sources, including nearby arterial roads and an active rail corridor, resulting in varying noise exposure across the development.

In addition, certain outdoor amenity areas were located in more exposed portions of the site, requiring careful consideration to maintain usability. The integration of mechanical equipment within the building design also required coordination to minimize potential noise impacts on both future residents and adjacent properties.

Approach

SSWA completed a comprehensive review of the surrounding noise environment, considering both existing and future conditions. The assessment focused on how nearby roadways, rail corridors, and adjacent developments could influence the site.

Our work included evaluating noise from major roads and rail lines in the area, reviewing the site layout and building design to understand exposure levels, and assessing outdoor amenity areas and building façades. The study also considered potential impacts from building mechanical systems and developed practical, coordinated mitigation strategies.

Results and Solutions

The study found that noise levels varied across the site depending on location and exposure to surrounding transportation sources. Some outdoor amenity areas required mitigation, while others naturally achieved appropriate sound levels.

Indoor noise considerations were also identified across the building, with a range of measures recommended to support comfortable living conditions. In addition, mechanical systems were reviewed to ensure they would not create adverse impacts on residents or neighbouring properties.

Overall, the assessment demonstrated that the development can be designed to achieve suitable noise conditions through a combination of planning, architectural, and engineering measures. 

SSWA developed a coordinated set of mitigation strategies tailored to the site, including the use of acoustic barriers to improve outdoor amenity areas where needed, as well as building design considerations to support indoor comfort. Recommendations were also provided for the design and placement of mechanical systems to manage on-site noise sources, along with standard warning clauses to inform future occupants. These measures were integrated with the overall site design and aligned with applicable guidelines, supporting a practical and implementable outcome.

Outcome

The study supported the advancement of the proposed development by demonstrating that noise impacts can be effectively managed through thoughtful design.

SSWA’s work provided clear direction for the project team, helping to streamline approvals and ensuring that future residents will benefit from a well-planned acoustic environment.
