• Williams Street Culvert

  • The small township of Dayboro, situated north-west of Brisbane, was established in the late 1800’s and is a popular tourist destination. The community has expanded over the years but the town centre still boasts historic stores including a butchers shop, post office, former bank building, and the Crown Hotel. However, the centre’s susceptibility to flash-flooding has caused serious impact on daily life for local residents and business owners alike.

    In a bid to find a solution to this issue, AllenCon was engaged by the local council to undertake the removal and replacement of existing drainage culverts in the town centre and therefore provide an answer to the problem.

  • The close proximity of local businesses to the work site required some unconventional staging with the upstream portion of the culverts being constructed first.  This method required extensive weather-proofing to the exposed excavation – the remaining road embankment – so that Williams Street would not be subjected to any erosion should there be a storm event during construction.

    The location of the works also necessitated significant traffic control measures that were implemented using single lane/traffic light controls with half of the works completed initially, and the remainder completed following the traffic switch.

  • In keeping with the look and feel of the historic township, the exposed concrete surfaces of the headwalls and wing walls were clad with recycled hardwood resulting in the appearance akin to an old timber bridge.

    With significant clearing and landscaping undertaken and the installation of new pedestrian paths the area remains an attractive stopping point for tourists and locals.

    The project was completed by AllenCon to the full satisfaction of the client and stakeholders alike.
