Abergeldie and Brisbane City Council worked collaboratively to deliver a complex, above-water infrastructure project. The Mariners Reach Riverwalk, a 440m superstructure built in 1907, required remediation to repair its degraded structure. Abergeldie successfully completed the partial demolition, reconstruction, and structural remediation of the boardwalk and pathway at Newstead along the Brisbane River, ensuring continued safe use.
The works included:
Mobilisation to site was delayed, with Council reconsidering the construction methodology, noise controls and temporary traffic management arrangements to address concerns of potential disturbance of amenities to residents in the vicinity of the works.
Once site possession was granted, our team completed a detailed survey of the site as a 3D scan. This process picked up the precise positions of the existing piles to inform specifications and dimensions for procurement of the FRP materials for the headstocks, joists, and decking. The 3D survey also captured the positions of the existing handrail and stanchions, which were superimposed onto the new design to document the precise positions of joists under each stanchion. This enabled the headstocks to be marked up accurately when they were set out on site.
Adding to the complexity was the location of the works. With the works occurring over/near water, strict safety and environmental controls were put in place.
Constructed in 1997, the former Riverwalk featured a timber deck with ground-level concrete paving, supported by timber and concrete piles with concrete headstocks. Continuous use over the years diminished its structural capacity, rendering it unsafe for public use.
The completed works strengthened and improved the structural integrity, revitalising the riverwalk for daily pedestrians, cyclists, and tourists.
