Firth of Forth, Scotland, UK · 2002–2011 (10-year project) · £130m
The judgement call
Account-gated at launchThe project successfully ended the famous adage "painting the Forth Bridge" as a metaphor for a never-ending task, with the new paint system expected to last for decades. - Demonstrated the challenges and complexities of maintaining iconic, large-scale heritage railway infrastructure. - The use of encapsulation allowed for year-round working and improved environmental protection.
Key engineering challenges
Undertaking a massive repainting and restoration project on a Grade A listed (UNESCO World Heritage Site) structure while it remained operational. - Developing and implementing innovative scaffolding and encapsulation techniques to allow work in all weather conditions and contain paint debris. - Managing the logistics of a decade-long project with minimal disruption to rail services. - Preserving the historical integrity of the bridge while applying modern protective coatings.
