Logan River Red Bridge Rehabilitation
As part of Logan City Council’s Panel of Preferred Providers for Civil Construction Services, ALLROADS was awarded the contract to undertake full scale remediation of the iconic 1930’s Red Bridge over the Logan River and adjacent to the M1 Pacific Motorway.
Works under the contract involved structural concrete repairs, concrete crack injection, structural steelwork re-coating, steel water main protective coating, bridge joint repairs and application of an anti-carbonation/waterproofing concrete coating system.
The majority of the works were undertaken over water inside of a large, fully encapsulated scaffold so that all waste, runoff and coating products were captured to ensure no adverse effects to the marine ecosystem of the Logan River below the bridge. Silt booms were used for works around the piers where the encapsulated scaffold was not possible due to tidal forces.
Upon the development of a scaffold design the existing dilapidated bridge was found to be unable to withstand the forces of potential high winds which required a wind management plan to be put in place including the establishment of a 24-hour weather monitoring station and on-call operatives to remove the scaffolding encapsulation in the event of high winds.
As the bridge was unable to be closed during the works so the scaffold design included a fully hoarded, illuminated tunnel which pedestrians and cyclists could use to pass over the bridge as usual.
One span of the bridge passed over an adjacent roadway requiring the development of a Traffic Management Plan and subsequent Council Permit for partial lane closures which was implemented safely to ensure minimal impact to road users.
Breakout, reinforcement preparation, and repairing of approximately 700 separate concrete repairs using hand applied and form-and-pour methods throughout seven deck spans and three bridge piers
Concrete preparation and application of 1,200m2 anti-carbonation coating
High pressure washing, sand-blasting and re-coating of structural steelwork of 3-span truss bridge using zinc-rich epoxy primers, two-component epoxy sealers and modified epoxy mid coats and coloured aliphatic acrylic polyurethane top coats.
