Pedestrian Bridge Structural Repairs
Restoring Safety to a Crumbling Bridge
When structural deterioration rendered a key pedestrian bridge at a new York state college unsafe for student use, immediate action was critical. Missing and damaged concrete, combined with severe deck cracking, posed significant risks to campus safety. A bold and innovative approach was required to restore the bridge’s integrity and ensure long-term reliability.
Experience always overcomes challenges
The proposed solution presented unique challenges, including:
Significant cracking and concrete damage had compromised the bridge’s load-bearing capacity, demanding a robust solution
The unsafe condition necessitated a quick yet durable fix to ensure safety without prolonged disruption.
Inspection and Preparation
CFES conducted thorough inspections and meticulously prepared the site to ensure the success of the repair:
Surface Preparation:
Damaged concrete was removed, and the substrate was cleaned and leveled.
Cracks in the deck were filled and sealed to prevent further deterioration.
Material Selection:
A Detailed structural engineering plan was developed for the reinforcement placement.
The team developed a tailored turnkey plan to maximize the repair’s effectiveness.
Innovative Repair Methods
CFES implemented state-of-the-art techniques to repair and reinforce the pedestrian bridge:
Carbon Fiber Application:
High-strength uni-directional carbon fiber fabric was applied to the underside of the deck, significantly enhancing its load-bearing capacity.
Anti-Slip Flooring Installation:
A specialized anti-slip flooring system was installed on the topside deck to improve safety for pedestrians.
Integrated Approach:
Repairs were completed efficiently, minimizing disruption and ensuring seamless integration with the existing structure.
Key Outcomes
Restored Structural Integrity: The bridge was reinforced to safely handle pedestrian traffic.
Enhanced Safety: The anti-slip flooring system reduced the risk of accidents.
Cost Savings: The repair solution was significantly more cost-effective than a full replacement, saving time and resources.
Extended Lifespan: The carbon fiber reinforcement and epoxy systems ensured long-term reliability and durability.
