The project incorporated an innovative design of a rolling scaffolding. This system is unique to this project, creating a temporary roof structure during roof replacement works. The current bespoke system is light enough to account for the building’s weight limitations and is completely mobile for all phases. The rolling scaffolding also allows for simple logistics management and quick adaptations that come with working in a live environment.
Roof replacement works were carried out, including slate replacement, glazing replacement, timber repairs, and safety-access walkways. DBR Leadwork carried out lead replacements and repairs, and flat roof covering replacement.
Lead patch repairs and replacements were carried out on the Mammals corridor roof. Lighting protection, fire systems, and safety walkways were added to the roof for further safety and longevity of the building by museum incumbents.
Terracotta cleaning and repairs and internal decorative schemes conservation have been undertaken by the DBR Conservation team. This included careful latex poultice cleaning of all terracotta elements and fully refurbished gallery ceiling using heritage paints. Historic internal oak flooring were repaired and refinished throughout the gallery wing. Cast iron floor grilles were repaired and refinished as well.
As this project was carried out in a live environment, careful cooperation is being taken by DBR teams and NHM stakeholders to ensure safety to all members of the team and visiting members of the public. Logistics planning, scaffold management, stakeholder engagement and open communication between parties are paramount to the success of this project.
