Project Overview

To create a lightweight curved roof spanning ±47.8 m, covering a 47.8 × 31.6 m courtyard, supported on tree columns. The atrium roof is 40m wide by 50m long in plan and comprises of a series of orthogonal primary and secondary 2D steel trusses. Each primary truss spans 50m in the east-west direction and is supported at 10m intervals by branching tr

Project Details
The majority of the steelwork was fabricated into 10m long sections at Tass Engineering's Factory. The truss internal tubes were laser cut by tube laser to ensure a perfect, clean fit. Once the individual roof components were fabricated, each of the four main roof quadrants were pre-assembled upside down at the workshop by means of purpose made jig
The existing building could not carry much load. As a result, the original design of a glass roof with a thrusting design was changed to lighter ETFE cladding with a non-thrusting design. The main columns are nearly 24m long. The columns had to be made by using 2 x 12m standard lengths to shop join and weld before sending to site. The full length of tube had to be placed on specially made supports with rubber wheels perfectly lined up to ensure the tube remained straight when rolling the pipe slowly while welding. Due to the size of the column Rissik street needed to be closed for the installation of these columns.
Benefits of Steel in this Application

We could create a lightweight long span structure, with a high degree of accuracy and limited onsite connections. This resulted in an elegant steel structure which enhances the heritage building.
