Brownhill Creek, Whites Road Footbridge

Client: Department of Environment, Water and Natural Resources
Construction Period: 4 Weeks
Value: $215,000

Project Scope: Design and construction of a new 18m long clear single span pedestrian bridge adjacent the existing herniate road bridge at Whites Road Brownhill Creek, the project scope includes concept design consultation, detailed structural engineering design including steel girders and bearing piles, site preparation, steel fabrication, screw pile abutment construction, in-situ concrete pile caps, installation of the steel bridge structure and placement of FRP decking and balustrading.

A key project consideration was to integrate the bridge structure into the existing abutment space. Designing footings and pile caps to fit around the existing services and providing a deep screen to “mask” the large steel conduits carrying water, sewer and communications conduits across the bridge. 

Value added options: The bridge was constructed from cutting edge materials but made to have a “heritage” look befitting the area of the installation.
Problem Solving: Fabricating the bridge on site but not in-situ enable the existing road bridge to remain open for the majority of the construction period and also ensure a safe construction method was employed.


Ayr Avenue, Torrens Park - Bridge Replacement

Client: City of Mitcham
Construction Period: 32 Weeks
Value: $880,000

Project Scope: Camco was engaged by council to demolish the existing condemned bridge followed by the construction a new culvert bridge and road over Brownhill Creek at Ayr Avenue, Torrens Park. The project scope included; site clearing, tree removal, road pavement removal, demolition of the existing concrete bridge structure followed by construction of new in-situ concrete base slab, placement of new pre-cast culverts, construction of the in-situ headwalls, coordination of third party service providers who installed new gas main, water main and Telstra NBN infrastructure through the new road over the creek, construction of new stormwater side entry pits and pipes. Construction of erosion protection via gabion rock walls and rock lining. Construction of new concrete barrier and concrete posts with galvanized steel barriers, new kerbing, road pavement construction, footpath and landscaping.

Value Add: Camco was able to provide certified clean fill as back fill to replace creek rock that had been used on site to build the road originally 80 to 100 years ago.
Problem Solving: The roots of a significant tree were growing into the new footing location, Camco worked in conjunction with the design engineers to construct a suspended concrete outlet from the culverts, to avoid the root system.
