Bothar have commenced the construction of the 1385m subsea crossing for the Gold Coast City Council in Queensland, Australia. The 2500mm OD reinforced concrete jacking carrier pipe will be utilised to convey a treated effluent discharge line to a reception shaft at South Stradbroke Island. The launch shaft is a 26m deep, 12.5m diameter secant piled construction and the reception shaft is a 7.5m diameter 26m deep pre-cast segmental sunk caisson. This sub sea crossing will be constructed underneath the seabed of an environmentally protected area of Moreton Bay, providing for its continuous use by the local community for boating, fishing and recreational activities.
