Thevenard Island Retirement Project – Deconstruction

The Project

AGC was engaged to carry out deconstruction works at the Thevenard Island facility in preparation for the site to be rehabilitated into a Nature Reserve.

Continuous Improvement Initiatives

• Machinery demolition was the preferred option of deconstruction on site to reduce risk of soft tissue injury, however there were numerous buildings that contained insulation material that easily became wind-blown debris when using the machine. Manual removal techniques were introduced prior to machine demolition to remove the easily wind-blown materials, while maintaining personnel safety.
• All the demolished material is shipped off island via barge where deck space is a premium. Trailer bolsters were procured to allow the stacking of pipe lengths on trailers directly, saving time on loading and maximizing trailer space.
• The AGC onsite team assisted the CVX project team in scoping and developing plans for additional works that could be performed by AGC without the requirement for manning up or bringing in additional equipment, using remaining budget from savings realized from the initial scopes.
