Operation of the Bunbury Storm Surge Barrier and Security of Jetty Road Facility – Casuarina Boat Harbour

⁠⁠⁠Overview

The Department of Transport and Major Infrastructure (DTMI) is seeking a contractor to operate the Bunbury Storm Surge Barrier and provide security services at the Jetty Road Facility and Casuarina Boat Harbour.

About

DTMI works to provide safe, accessible, sustainable and efficient transport services that promote economic prosperity and enhance the lifestyle of all Western Australians.

The Bunbury Storm Surge Barrier is located at the western end of the Leschenault Inlet. The barrier was constructed in 1980 following flooding of the Bunbury townsite during cyclone Alby in 1978. The barrier is operated during periods of extreme high ocean water levels, isolating Leschenault Inlet from the Indian Ocean, with the aim of preventing ocean flooding of low-lying areas of Bunbury.

DTMI is also responsible for the management of the Jetty Road causeway and its associated infrastructure, including the public ablution facility and heritage Arrol crane, which is non-operational but heritage listed and therefore needs to be protected. This is located in close proximity to the barrier. Additionally, DTMI manages the new public toilet facilities at the Casuarina Harbour Boat Ramp and requires routine locking and unlocking of the public ablution facility.

Purpose

Whilst the Storm Surge Barrier has been designed to provide protection of Bunbury against ocean flooding, it is integrally linked to the drainage of Bunbury CBD. Careful consideration must be given to extended closure of the barrier due to the potential for backing up of the CBD drainage system and threat of flooding from rainfall runoff.

The scope includes:

• Operation of the Bunbury Storm Surge Barrier 24 hours a day, 7 days a week, in accordance with the Bunbury Storm Surge Barrier Operations Manual (April 2021) (Attachment 1)
