Granite edifice becomes modern steel framed headquarters

The world’s second largest granite building, Marischal College, is undergoing a full scale conversion to provide a 21st century corporate headquarters for Aberdeen City Council.

The Grade A listed building, renowned as a city centre landmark, is being reconfigured to create 18,500m² of office workspace across four floors.

All of the historic facades have been retained and new steelwork is being inserted to form new floors in four wings around an internal quadrant.

ASD Westok has supplied cellular beams for all of the project’s floors, which have spans of 10m and 7m. The majority of the beams are 550mm deep with 300mm diameter openings at 450mm centres.

The project’s structural steel frame has now been completed and main contractor Sir Robert McAlpine has now commenced work on the new roof.
