Sunnyside Bridge (No 600) Replacement

⁠⁠⁠This design and construct documentation is for the replacement of the Sunnyside Bridge (no. 600) over Iron Creek on Nugent Road and realignment of approximately 450m of road. The bridge is located approximately 2km north-east of the junction of Nugent Road with the Arthur Highway. Sorell Council requires the replacement of the existing two lane timber bridge as it is near the end of its service life. The intention is to build the new bridge alongside the existing bridge on the upstream side to allow the existing bridge to remain in service during the construction and realign the road to provide improved road approaches as the current road approaches are very tight and not suitable for larger/heavy vehicles.

The scope of works under this Contract shall consist of all work necessary for the Design and Construction for the replacement of Sunnyside Bridge No. 600 and realignment of road approaches, including, but not limited to:
a) Undertake any further site investigation and/or additional survey work necessary to complete the project objectives and requirements.
b) Undertake any further hydrology and hydraulic assessments required for the design of the replacement bridge.
c) Carry out the design of the new two lane bridge to AS5100 design loads, including SM1600 vehicle loads, and the required design checks.
d) Carry out the design of approximately 450m of road realignment, in accordance with Austroads standards, including the necessary design checks.
e) All temporary works and associated design that may be required to carry out the construction activities.
f) Preparation, implementation and maintenance of all required temporary traffic management required to carry out and complete the construction activities.
g) All construction activities associated with the construction of the new bridge, including: foundations, abutments, piers, decks, fences, and guardrail transitions to approach rails.
h) All works associated with the approximate 450m of new road approaches on improved alignment including 35m of a new property access.
i) Complete removal and disposal of the existing bridge including the foundations to a level of at least 300mm below the existing ground or riverbed surface.
j) The removal and rehabilitation of the redundant road.
k) As constructed drawings and QA documentation in line with the requirements of the contract.
l) Any other works as required to fulfil the requirements of the project objectives and requirements.
m) Clean up of site including make good of any disturbed areas, and reinstatement of any damaged infrastructure.

Use of the existing bridge structure for the construction of the new bridge shall not be permitted at any time without the approval of the Superintendent.
