The Department of Biodiversity, Conservation and Attractions (DBCA) requires a suitably qualified maritime engineering consultant to deliver structurally certified designs for the construction of replacement boardwalk structures over water bodies at the Thrombolites within Yalgorup National Park, Mandurah, and the Stromatolites at Hamelin Pool within the Hamelin Pool Marine Nature Reserve in Denham, south of Shark Bay.

Both structures have recently been assessed as requiring replacement due to storm damage or poor condition. Both sites, have environmental significance and the design and construction methodology of the replacement structures will need to consider these requirements along with restricted access for any plant and equipment. DBCA will provide relevant approvals and conditions to guide the design process.  

The delivery timeframes for each site vary due to funding constraints with the Thrombolites planned completion date of December 2025 and Stromatolites October 2026.

A briefing session will be held at .

A non-mandatory tender briefing to the Respondents is strongly encouraged and will be undertaken by appointment within the first two (2) weeks of this Request being advertised. To arrange your appointment, contact the below person:
