Gold Coast City Council engaged Alder Constructions to conserve the 113 year old ex-railway bridge and associated civil infrastructure at Currumbin. The renewed bridge is wider than the existing bridge and the heritage of the existing structure was retained. Environmental considerations were a high priority.
In order to save costs for the Client, Alder Constructions designed and constructed a specially designed hydraulic scissor lift that was fixed to a floating barge. The lifting device was used to float and place some of the precast concrete deck units onto the bridge piers near the centre of the creek.
Some of the key components of this Project were:
- Upgrade and refurbishment of the existing bridge substructure components that include wrought iron girders, cross beams and cast iron columns.
- New bridge substructure components including precast concrete headstocks.
- Construction of new precast concrete deck, stainless steel barriers along the bridge including approaches, connecting paths, lighting and utility services.
Benefits to the local community included:
- Improved pedestrian and cycle facilities.
- Retention of local heritage.
- Improved safety.
