Liberty Industrial was engaged to decommission and demolish the former Valspar Paint and Resin Manufacturing Facility. The scope of works included demolition to existing grade and removal of all equipment, building materials, structural steel and wiring of Paint/Resin manufacturing building, large tank farm, wastewater treatment plant and support buildings such as the dangerous goods store, maintenance workshop and waterbased technology plant. Structures to be retained included all building concrete foundations and slabs on the ground, retaining walls, pavement and roads at the site.
Robust solutions
- Live services such as the domestic and fire hydrant water supplies and the gas and electrical supply line were disconnected. The switchroom and two transformers were protected.
- Due to the flammable nature of the materials stored onsite, all tanks and process vessels were ventilated, cleaned in place and cut into manageable sections with a non-sparking cold-cutting process.
- The main 4 storey paint/resin building was demolished using the 48-tonne Volvo excavator with a 24m high reach arm and 5t shear attachment.
- All Asbestos-containing insulation in the electrical boards were removed safely.
- Environmental controls such as a rainwater division from the Paint/Resin building and firewater pond were implemented.
- Various scrap materials across the site were removed and recycled.
- Marine diving works were carried out to cut and remove the pump house located in the firewater pond.
- Concrete crushing of 7000t of demolished masonry material.
- Backfill of the caustic and wastewater pit, processing vessel pit, cooling tower pit and the former tank farm area void.
- A stabilisation wall made of soil nails, mesh and sprayed shotcrete was designed and constructed across the elevation to protect the exposed embankment on the northern and eastern elevations of the building.
Exceptional outcomes
Liberty Industrial completed the project to the agreed schedule and with zero incidents.
