The first six floors consist of unitised facade panels, approximately 3m x 3m, the remaining upper floors consist of a Kawneer ‘stick’ curtain walling system. It had become clear early on, that there were several significant constraints with the concrete frame design, which was found to be incapable of directly supporting the external facade. NACWL worked closely with the design team, and Bouygues, to develop a solution that involved an additional steel carrier frame for the facade. On which the stone cladding could also be hung. The finished project is testimony to the innovative approach that NACWL were able to bring to the project, by working collaboratively with the other parties involved.
