The Waidamu Bridge project involved the design and build of a 14m single span replacement bridge on the existing alignment with a combination of T3 precast beams and in-situ concrete. Works involved construction of a temporary bailey bridge and road, demolition of the existing structure, around 160m of embankment and road approaches, along with associated service relocations and drainage work.

Access staging allowed a 55T crane plus other service equipment to construct abutments and place precast beams away from the existing damaged bridge. A T3 beam was adopted in lieu of a modular steel bridge, leading to cost savings and improved durability.

The local community was engaged throughout the project, including holding a traditional ‘Sevusevu’ prior to the works commencing. Improvements to neighbouring residents’ driveways and the local police station driveway using leftover concrete helped to upcycle waste material and provide material benefit to the community.
