Walz were engaged to complete the Structural, Mechanical and Piping construction scope for the main kiln bag filter replacement project, at Cement Australia’s Gladstone plant. The scope of works included the unloading and destuffing of all free issued materials, preassembly, and installation of 600T of structural steel and platework. Due to the short timeframe in which to complete the installation of the new bag filter during the site major shutdown, a methodology that included the preassembly of the new bag filter on temporary foundations and relocated using SPMTs was developed, to reduce the overall duration required during the shutdown to complete the installation and mechanical commissioning.  

Key highlights included: 

• Handling and unloading of 90+ containers and flat racks 
• Preassembly of 8-off 30T filter casings and installation using 150T Kobelco crawler crane 
• Erection of 170T of structural steel 
• Design and installation of 30T of falseworks, to enable the SPMT relocation 

SPMT relocation of the 450T new bag filter structure a distance of 60m 

Installation of 3,500x 10m long filter cages and bags
