Project Background
The Montevetro Tower Building is 67 metres high and, under Google’s instruction, required the construction of ‘pod’ type office units which, in essence, are based on lightweight partitioning systems with either a glazed or open front elevation. The original design for the ‘pods’ was based on a timber frame structure as there were specific acoustic requirements in terms of sound reduction.
The Challenge
Severe noise limits and limitations in terms of building access were imposed on the site as part of the project contract.
The Approach
Sound reduction performance was achieved through the use of our lightweight framing systems. Creating the framing systems involved installing structural box section steel posts from which could span horizontal ShaftWall systems incorporating Gyproc FireLine plasterboards. This was the only horizontal system available which had specific tested acoustic performance which could meet the required performance criteria to form the ‘lids’ of the pods. Our framing systems, in addition to having superior acoustic advantages, were also more flexible in terms of usage, and had an advantage in both time and labour savings.
Gyproc partitions incorporating two layers of Gyproc WallBoard to each side of a 70mm Gypframe stud were fixed to the underside of the supporting steel box section system to form the side and rear walls to the ‘pod’. The use of the Horizontal ShaftWall spanning between the structural box section enabled the suspension of a Gypframe CasoLine MF Ceiling system with Gyproc Rigitone ceiling boards for superior acoustic performance within the pods. The design of the pods, and the telephone booths, ensured that the required sound reduction performance was achieved with Gyproc plasterboards and Rigitone boards.
