Sometimes it pays to look twice at received ideas about what works and what doesn’t. By questioning some basic assumptions, we were able to provide cost-saving innovations on this HQ development in Aberdeen.
Three buildings are connected by an internal fully-glazed triple-height ‘street’. Comprising a total of seven wings, the buildings project out on either side of the street, so the overall structure is roughly star shaped on plan. Each three-storey building is steel framed and is clad in glazing and rendered panels. Two atria book-end the development, and a long span stair provides a visual focal point.
Precast concrete hollow-core floor panels are used throughout. Following detailed analysis of the interaction between the steel frame and concrete elements, we were able to prove that the steel joins were sufficiently robust to secure the panels, without the additional steel ties normally used to lock floor elements into place. This saved time in construction and reduced overall cost.
We applied a similar outside-the-box approach to the analysis of the atria facades, proving that smaller mullions could be used to support the glass panels.
