Structural Assessment of Protective Bollards for a Municipal Transit Facility- Toronto
Parsways completed a detailed structural assessment and capacity verification of concrete-filled steel protective bollards installed to safeguard above-ground diesel fuel tanks at a municipal transit facility.
The assessment evaluated as-built alignment variances, impact resistance, and overall serviceability in accordance with OBC Part 4 and CSA S16 structural standards.
1 | Project Overview
Location: Arrow Road Garage, Toronto, Ontario
Completion: 2024
Sector: Transportation / Industrial
Scope Highlights
-
Structural condition assessment and impact performance analysis
-
Finite Element Analysis (FEA) for bollards installed with eccentricity
-
Soil–structure interaction modeling
-
Field verification and sealed engineering report
2 | The Challenge
-
Addressing misaligned bollards resulting in non-uniform load transfer
-
Increased bending demand at the caisson–bollard interface
-
Need to confirm structural adequacy without requiring reinstallation
3 | Engineering Results
-
Modeled impact response using detailed FEA simulations
-
Verified soil–structure interaction and realistic boundary conditions
-
Confirmed all bollards meet required impact-resistance and code criteria
-
Delivered a sealed engineering report authorizing the installation to remain in service
