Here are some construction time-lapse videos from the Wivenhoe Dam upgrade which occured between 2003 and 2005. The main aim of the project was to flood proof the dam to protect the main spillway during a 1 in 100,000 year flood event along with the protection of ten critical bridges downstream. Another benefit was the temporary increase in flood storage. Other upgrades were the information centre on the western side of the dam wall, the entrance to Cormorant Bay and other legacy works in the region. Wivenhoe Dam has two purposes being to provide flood mitigation to protect Brisbane and is the main water store to South East Queensland. Additional info can be found here at Seqwater, Leighton Contractors and Wikipedia. All time-lapse was captured using a Canon PowerShot S45 tethered to a notebook. Shooting interval general varied from 5 - 7 seconds with the odd one at larger intervals. Here is a sample video with a few clips Earthworks Activities Various big boys toys were used during the excavation of the spillway chute including dozers, trucks, excavators, graders and a road profiling or milling machine. Downstream Chute Earthworks I shall include more over time.
