Project Summary

As part of the overall development, Grankraft was also awarded a contract for the architectural metalwork for the 5-star Marriott Hotel which has over 300 rooms and is directly linked to the convention centre for which Grankraft has also fabricated and installed the skylight of the connecting passageway. The main items of this scope were the twisted, perforated aluminium fins with a PPC finish which act as shading structures and are the prominent feature of the hotel’s entrance area and guest rooms. Overall, hundreds of pieces have been fabricated, each having more than 300 perforations, with a radius of 15mm which were cut using a water jet. The 4mm thick plates are 3m long and were cold-formed by bending the aluminium panels on a rolling machine. A very strict quality control procedure was followed to ensure the consistency of the finish and geometry.
