Olympic Dam Feed Prep Area Filter Building Remediation
KAEFER was engaged by BHP to undertake a full structural refurbishment of the Feed Prep Area Filter Building, located in the Metallurgical Plant of Olympic Dam Mine.
The works included replacement of the wall cladding, replacement of the wall cladding support structure, replacement of the louvres and other itemised opportunistic structural repairs. KAEFER was responsible for procurement of steel channel, plate and fastenings, manufacture of fabrication packages and preparation and application of the protective coating system. The building was required to maintain full operations during works.
Our Scope
- Remediation of 116 structural defects
- Completion of 84 additional out of scope items

- Replacement of the standard rolled steel cladding support girts with enhanced 200 x 70 PFC cladding support, complete with trusses and sag supports
- Replacement of Colorbond cladding with Ampelite Wonderglas cladding on all 4 elevations
- KAEFER utilised a fully-engineered mono rail and hoist system on all four elevations of the building to enable our teams to access work fronts and undertake removal and replacement of the support system and cladding. This access system negated the need for cranage and elevated work platforms for our teams to access work areas.
