Under a design and construct contract with Marine & Civil, BG&E documented a new concrete deck for the pier head of the jetty, replacing the existing timber deck. The existing timber deck comprised hardwood timber rafts supported on steel beams forming part of the pier substructure. The hardwood used on the deck had gaps and was warped and unsuitable for access and as an operating platform.

The Australian Government had the following concerns with the existing decking: safety for personnel and public access; lack of availability of replacement hardwood in the event that the deck was lost in a cyclone.

After extensive consultation, the preferred alternative was to replace the existing timber decking with a deck constructed of concrete. The new deck was designed to maintain existing and future live loading conditions and provide safe access for future stakeholders.
