Key challenges and Mackex Services solutions
A further challenge was encountered with the installation of conduits under the traffic platform at Guilford Train Station. The design required the installation of 4 x 150mm conduits in a crawl space. With the limited access this was identified as a safety risk working in such a confined space. To address this challenge, the Mackex Services project team developed an alternative methodology to first install 4 x 160PE pipes using a winch system, through which the cables were subsequently pulled.
This was successfully completed within the limited possession period with no issues. As a result of this successful project, Mackex Services was awarded further permanent works for Guilford, Minto and Ingleburn Substations.
