SPECIAL MEETING AGENDA                                                              30 AUGUST 2021


      Stage 2
       -    Full road closure for an estimated 72hr period. Pedestrian traffic will continue to provide
            access during this period via the temporary pedestrian bridge.
       -    SGQ will demolish existing bridge, expose pre-built abutments, and install deck units
            and guardrails.
      Stage 3
       -    3 weeks expected (weather permitting) to complete final works, which will
            include asphalt, approach works and signage.
       -    Road closure is expected on working days between 8am-4pm. Pedestrians will still have
            access.
The abovementioned construction and communication approaches were requirements within the
tender specifications, which contractor SGQ will comply with.

5.     SP2 – Wahpunga Lane Bridge – access during construction
Weather permitting, Wahpunga Lane Bridge will have a relatively short construction duration of 12
weeks, due to the prescribed construction method using mostly prefabricated bolt-on components,
combined with a bored piling solution. During the temporary road closure, a detour will be available
along Sister Creek Road and Gympie Kin Kin Road. During construction, part of the Noosa Trail
along the bridge location will be temporarily closed off.

Finance
The current budget allocated to the 2 bridges is insufficient to cater for the tender award for both
bridge projects. Key reasons are:
      Unforeseen scope increase include resident access and disruption, site constraints and limited
       access to reach Tablelands Road Bridge B.
      Scour issue near Wahpunga Lane Bridge has been incorporated into the scope.
      A saturated market has resulted higher tender pricing than anticipated and higher than cost
       estimates based on previous project cost.
      Recent further increases in steel market pricing (post tender submission by suppliers)
The below tables summarise the updated project cost estimates. The total cost of the 2 bridges
replacements is now estimated at $4.1 million.
