Tower 2 Collins Square Project is Towering 2 The sky
The Walker Corporation’s latest Tower 2 Collins Square Project is a towering masterpiece. The building is part of the $2.58 billion Collins Square development in Victoria – one of the biggest commercial developments in Australia. Designed by award-winning architects and offering 38 storeys of office space with a construction value of $340M, this building makes an immediate impression.
The construction company (Brookfield Multiplex) engaged CoxGomyl (a leading manufacturer of building maintenance units or BMU’s) to provide a solution to access all facades of the building. An array of possible solutions was considered, with the shift in floor plan below Level 27 creating a step in on two of the four elevations and presenting a particular challenge. To access the areas below the step, the BMU cradle was required to reach in towards the building and under the step itself. For the areas not affected by the step-in the BMU features a dedicated built in glass-changing hoist. To facilitate changing glass in the areas below the step in, a monorail system at Level 27 was installed on the underside of the ceiling. A winch lifts a glass panel from the ground with support from the operators in the cradle and the panel is moved to the replacement location where the BMU operators install it. The BMU travels around the roof area on a steel twin track system, much like a railway track, which guides and stabilises the machine.
The distinguishing feature of the BMU’s is the cradle’s ‘Self-Approaching Mechanism’, known as a SAM Cradle. a scissor- type mechanism and stabilising counterweight gives the cradle the necessary range of movement to navigate the building. The operators initially descend the facade from roof level with the cradle in the collapsed position. Once they have passed the step in, the cradle system is “opened” effectively reaching in underneath the step and providing access to the facade below this step in.
CoxGomyl have developed a wide range of solutions to suit all building challenges and requirements, working with the architect and builder to find the right solution which is always project specific.
