Project Overview
The White City Overbridge forms a key part of Imperial College’s campus expansion, providing a vital connection between facilities.
The project required precise coordination to fabricate and install the 25-meter-long structure over a live railway line. Challenges included integrating utilities and managing minimal possession hours.
Our Approach
Carver Engineering Services worked closely with Careys and the project design team to ensure the overbridge met both structural and aesthetic requirements.
By leveraging our Doncaster-based fabrication facility, we completed over 60% of the work off-site, including trial erection and the application of protective coatings.
We employed modular construction techniques to minimise on-site activity and ensure efficient assembly. Utilities were pre-installed within the girder assemblies to streamline the process further. Our use of just-in-time deliveries reduced disruption to railway and local infrastructure operations.
Execution and Installation
The bridge comprises eight braced plate girders, soffit panels, and secondary steelwork. Each section was pre-assembled off-site to save time and ensure accuracy.
When it came time to install, we worked during scheduled possession hours, using craneage to position the girders quickly and precisely. Pre-installed utilities meant fewer follow-up activities on-site, streamlining the entire process. Every detail was carefully managed to ensure the installation went off without a hitch.
Once the overbridge was completed, the principal contractor for the project, Careys, began forming the concrete deck.
The outcome
The White City Overbridge was completed on schedule in May 2024, with a goal to open the bridge for both vehicles and pedestrians by winter 2024.
