The job
Deliver a replacement bridge over a railway to allow for electrification of the line. Existing plinths to be demolished and replaced.
Our involvement
Project management and delivery – a week ahead of schedule thanks to accurate planning and engagement with crane providers and bridge manufacturers.
The challenge
A live railway requiring a cessation of services to allow for both bridge removal and replacement.
Our solution
We created a set of RAMS risk assessment and method statements for the pre-design work on site, and another set of RAMS for the time the line had to be closed.
We invested two months in the pre-planning phase as we wanted to be as quick as possible once the new bridge was manufactured.
This reduced the time required on site and ensured disruption was kept to a minimum for rail passengers.
We also carefully planned out the crane access to the site.
Once the line had been closed and the new bridge manufactured ready for replacement, we had a two week window for total completion of our timeline:
- Removal of existing metal bridge by crane
- Demolishing of existing plinths and removal to a local waste site
- Creation of new plinths
- Obtaining concrete samples for laboratory testing to ascertain strength
- Testing in situ of the base template of bridge to ensure fit with the new bolt system
- Delivery and fixing of the new bridge
- Painting of bolts for increased protection
- Creation of quality assurance report and submission to National Rail
