Project Summary

Grankraft joined the project team at the main contract tender stage. The initial involvement was to review the Corten steel façade, which is one of the main features of the buildings design. Grankraft worked with Alumet, a Dutch anodising company, that provided double anodising in about 2000 aluminium panels with a copper-rust pattern.

The double anodisation achieves a unique pattern as it enables the combination of two colours within the finish to mimic the design intent of the weathered steel appearance but reducing the weight of the façade. The different colours on the panels are produced with the electrochemical deposition of metal salts in the pores of the anodising layer. The aluminium is durable, corrosion-resistant, UV resistant, and has a life expectancy of over 80 years, without losing gloss or colour.

Grankraft’s involvement started upon receiving an IFC package of information and developed the BIM models to allow for the coordination of the project and further construction. The complete involvement from start to completion was around 2 years. In that time, the 40,000m² of external metal and glass façade and 10,000m² parasol were engineered and built. All cladding panels were mechanically fixed and then weather proofed with a concealed silicon joint.
