Challenges
The Cross Laminate Timber (CLT) Frame required detailed calculations of the loading of the Cladding package. Calculations also needed to allow also for the bracketry cantilever of the tiles, which project proud of the glazing.
The colour impact of the tiles is one of the highest impact features of the building, together with the overhanging roof and curved walls.
The Timber Frame required an Engineering Judgement on compliance with fire safety requirements.
Solutions
The combined load – of sub-grid, tiles, insulation and fire barriers – was engineered to the structural capacity of the CLT Frame. Pull-out tests were conducted on the proposed fixings before full installation.
A2O issued colour setting out drawings for the install team, for sign-off on developing the architect’s concept to full satisfaction.
A2O worked on fire compartmentalisation, with the architects, suppliers and fire engineers, to determine that the CLT and specified fire barriers would fully comply with fire safety requirements. The Engineering Judgment passed.
