Engineered access and weather protection for the restoration of a historic landmark
The restoration of the Category A listed Rothesay Pavilion on the Isle of Bute required a complex temporary access and weather protection solution. With 21 flat roofs at different levels, limited structural capacity and an exposed seafront location, the historic building placed particularly high demands on the design and engineering of the temporary works.
Scope
Built in 1938 and designed by architect James Andrew Carrick, Rothesay Pavilion is a prominent example of International Modernist architecture. As part of the extensive refurbishment of the historic building, principal contractor Robertson Central West Limited appointed Brand Access Solutions, formerly Lyndon SGB, to provide temporary works access, scaffolding and weather protection.
The solution combined CUPLOK® system scaffolding and UniRoof temporary roofing with edge protection and hoists. Work commenced in July 2023.
Challenge
One of the main challenges was the complex roof geometry of the Pavilion. The main building comprises 21 flat roofs at different levels, requiring access and temporary weather protection across multiple areas of the structure.
At the same time, the existing building had limited capacity to accommodate the additional loads imposed by the scaffolding and temporary roofing. Internal support scaffolding was required for the temporary main roof structure, while the temporary works themselves had to be carefully engineered to avoid overloading the historic building.
The main central temporary roof had a span of approximately 29.4 m, complemented by two smaller temporary roofs extending from the central structure. The Pavilion’s exposed seafront location on the Firth of Clyde added another challenge, making reliable weather protection particularly important for the refurbishment works.
As the project progressed, changing conditions and requirements called for multiple new temporary works designs.
Performance
Brand Access Solutions developed and engineered the temporary works in-house, combining CUPLOK® system scaffolding with the UniRoof temporary roofing system to provide access and weather protection across the complex building.
The temporary over-roof enabled refurbishment works to continue in different weather conditions, while the scaffolding provided access to the various roof levels and elevations. Where required, internal scaffolding provided additional support for the temporary roof structure and the building itself.
Close coordination between the engineering and site teams allowed the temporary works design to be adapted as the project evolved. Multiple revised designs were developed to manage the imposed loads and prevent the existing structure from being overloaded.
Up to six scaffolding operatives constructed the main access system, with a team of ten working on the roofing sections. Early involvement by Brand Access Solutions supported the planning and coordination of the complex temporary works, with the company reporting that its works remained on time and on budget.
