Project Description

As part of the Transit Project Assessment Process (TPAP), Noise and Vibration Impact Assessments were undertaken as part of the Environmental Project Report (EPR) for three proposed SmartTrack stations – Lawrence-Kennedy, Finch-Kennedy, and Gerrard-Carlaw.

The purpose of these studies was to evaluate the construction and operations noise and vibration impacts of the proposed Lawrence-Kennedy, Finch-Kennedy and Gerrard-Carlaw SmartTrack stations. Noise sources included train pass-bys, train bells, break squealing, bus idling and pass-bys, and road traffic.

Noise modelling was undertaken by means of the US Department of Transportation Federal Transit Authority (FTA) methodology using CadnaA. Vibration modelling was undertaken using FTA methodology using an in-house spreadsheet developed for the purposes of this project. Furthermore, noise and vibration field measurements were undertaken to calibrate the noise and vibration models. Based on the studies, it was concluded that the noise and vibration impacts on nearby sensitive land uses were manageable through mitigation, which included noise barriers at key locations. Since then, the Ministry of the Environment, Conservation and Parks issued a Notice to Proceed in accordance with the EPR.

LEA engineers Tony Chiu and Felipe Vernaza completed work on the project while employed with a previous firm.
