Back Creek Bridge - Design and Construction

Tenders are invited for 2026/192 back creek bridge - design and construction
The city of boroondara (council) requires a suitably qualified and experienced contractor to carry out the following works in accordance with this request for tender (rft) and its attachments. council invites the tenderer to submit a tender for the provision of the works in a design and construct capacity for the back creek bridge project.
the back creek bridge (the project) involves the design and construction of a new pedestrian and cyclist bridge over back creek. the project also includes the potential construction of an accessible shared path to provide a continuous connection between denman avenue and somerset road in glen iris. the shared path will require a retaining wall along its alignment. the project supports council’s vision to improve community connectivity, encourage sustainable transport, and enhance safety and accessibility along the trail.
the back creek reserve in glen iris forms part of the broader back creek trail corridor that extends north-south through the city of boroondara. the corridor is a key element of council’s open space and active transport network, providing important links between residential areas, local streets, and key community destinations.
at a high level, the proposed works include:
• a shared pedestrian and cyclist bridge connecting the east and west of the back creek reserve;
• handrail, lighting and bollards to the bridge;
• shared path connection (optional item);
• retaining wall (optional items) and
• design of the works
key objectives of the back creek bridge project are to:
• deliver a safe, universally accessible bridge crossing for pedestrians and cyclists.
• minimise environmental and hydraulic impacts on back creek and surrounding vegetation.
• provide a robust, low-maintenance structure with a 100-year design life.
• integrate the new paths and retaining wall into existing footpaths and roads with minimal disruption.
a preliminary design has been developed by ghd and stantec for the works. with neither ghd nor stantec being engaged to complete any further design requirements under the contract. council is seeking to engage a contactor to carry out the design and construction of works.
the preliminary design for the bridge construction has been based on a steel system. tenderers’ submissions are to be based on a steel system in order to be considered conforming.
however, council is open to tenderers proposals for alternative bridge construction systems. tenderers may submit alternative design options for the bridge construction, together with the reasoning for the proposed alternative(s), such as cost savings, time savings, durability, and/or design life.
any proposal for an alternative bridge construction system will be deemed non-conforming; however, it may still be considered and accepted by council.
the contractor will be required to perform the work strictly in accordance with:
• the requirements of the contract; and
• applicable australian standards, building codes, industry standards, the requirements of any authority having jurisdiction over the work, occupational health and safety acts and regulations, and manufacturers recommendations and requirements.
