With the Brisbane River at its doorstep, the use of stainless steel throughout this project has delivered several key benefits in ensuring the longevity of public infrastructure in a marine environment. Structural durability, corrosion resistance and visual appeal are just some benefits that stainless steel has contributed to the precinct’s improvement and development.
Stainless steel was delivered in spades for various components of the project, with ASSDA Member and Accredited Fabricator Stainless Engineering Services engaged for the fabrication and installation services. Forty-two road bridge expansion joints were fabricated in their workshop using 15t of grade 2205, 10mm and 16mm stainless steel plate, with material supplied by ASSDA Member Stirling’s Performance Steels. The cantilever bridge deck was constructed in 40m long concrete sections, and the expansion joint fixings were countersunk and bolted insitu to deliver a continuous smooth surface.
Additionally, Stainless Engineering Services delivered 1.5km of stainless steel top rails for the Lores Bonney Riverwalk, Kingsford Smith Drive’s riverside promenade. The riverwalk meanders from Bretts Wharf to Cameron Rocks Reserve and the top rail was specified to follow the flow of the river, presenting several challenges in its fabrication and installation. Furthermore, the top rail was specified to be delivered in 10m lengths. It was TIG-welded on-site using grade 316 stainless steel 150x50x5mm rectangular hollow sections (RHS) with a 600-grit finish. Different methods were trialled to achieve the curve specified and conventional manual means were applied to bend the RHS in-between the posts.
Stainless Engineering Services fabricated the stainless steel spigots from 32mm plate to suspend and clamp the galvanised balustrade panels, as well as other various stainless steel components including planter boxes, rung ladders for sewer and drainage manhole access and cover plates at all expansion joints along the boardwalk.
Stainless steel tube was also used for 300m of pedestrian and bike rails at Cameron Rocks Reserve, with material supplied by ASSDA Members Australian Stainless Distributors and Midway Metals.
