The 308 Exhibition Street project required our team to create a solution for working on an almost finished building. Our team had to create a solution to access without tying into the building. Usually large, weighted beams at this height are specifically for a building demolition – where there is minimal concern for preserving the building’s integrity.
At 308 Exhibition Street Tower 2, there were four engineered heavy-duty trusses, which were fabricated in-house at our facility. Our team designed square hollow round section trusses, which were bolted and fabricated at approximately 15 metres in length. The trusses varied in width from 1.2 metres to 2.4 metres and in height from 1.5 metres to 1.8 metres and weighed 7 – 8 tonne.
Once in place on Tower 2, there were three scaffold support modules, between the trusses. These square hollow sections trusses were designed with the capacity to meet future project needs where there may be a requirement for spans tower to sit on the truss.
A unique challenge for Tower 2, of this project, was the location of the site tower crane. The placement created narrow access and required the engineers to find a solution to the obstruction of the crane grillages. To overcome this, our team designed a support leg, customized to the exact size required to span over the obstructing angles on the crane grillages, with the introduction of additional bracings.
Our Engineering, Design, and Operations team worked collaboratively, combining their diverse perspectives and expertise, to produce a comprehensive and effective solution that met all requirements of the project. These square hollow sections trusses were designed with the capacity to meet future project needs where there may be a requirement for spans tower to sit on the truss.
We’re reliable, we’re respectful and we take responsibility.
