The Spacer Company were approached by the Transcity Joint venture (ACCIONA, Ghella and BMD Constructions) to provide a safe and efficient method for installing conduit into the twin 4.6km road tunnels.
The Spacer Company provided over 100,000 of the Injection Moulded 100mm Conduit Spacers for this Brisbane Twin Tunnel project.
The project involved design and manufacture of almost 800 custom ‘modules’ comprising 8m long conduits and a frame system to dramatically increase installation speed.
In 2013 The Spacer Company commenced a project of designing and building banks of conduit modules for installation into twin 4.6km tunnels running from Toowong to Kelvin Grove in Queensland. This involved the installation of over 250,000m of conduit.
Conduits for both electrical and communication were required in banks throughout the tunnel. Using the Spacer Company pre-fabricated modules the contractor was able to dramatically speed up the installation of these conduits.
The modules reduced the contractors job to simply bolting the modules to the side wall of the tunnel using the custom mounting bracket and gluing the conduits together. Bondek was supplied, fitted to each module to act as formwork for the backfilling process securing and protecting the conduits.
