Delivery of a Dam – Value through Innovation
Chris Dann
Hinze Dam is located near Nerang in South-east Queensland and has been the primary source of water supply to the Gold Coast. The dam was initially constructed in the mid 1970’s and then raised in the mid 1980’s to increase the water supply due to the continued population growth in the area. In 2006, during the period of extreme drought, the Gold Coast City Council decided to once again modify the dam. The Hinze Dam Alliance had to meet three key project objectives: flood mitigation, water supply & compliance with new regulatory guidelines. The project is to be completed in December 2010.
Industry and governments continue the debate on the advantages and issues with various project delivery mechanisms, in particular the Alliance delivery model. Chris’ presentation will discuss specific examples of value delivered through the Hinze Dam Stage 3 Alliance model through innovative methods & design.

Next Generation of Unsealed Roads
George Vorobieff
Theatre, Zenith Centre Cnr Railway & McIntosh Sts, Chatswood
Low volume rural roads are typically unsealed roads and numerous Australian and international studies have been carried out to improve their durability and reduce dust. New products and equipment have been produced and tested, and unfortunately many of these new products are typical promoted by the so called ‘snake oil’ salesman. The goal of the salesman is to sell more product and that equates to more profit, but a holistic approach to the Shires long-term needs are never considered.
A new approach has to be taken where any unsealed road maintenance incorporates the opportunity to incrementally strengthen the pavement, reduce maintenance frequency, improve drainage and reduce the use of depleting quarried sources. At the same time rural communities need and expect safe mobility between homesteads and township, and whilst rural road users desire a sealed road, Shires have limited road funding to build and maintained sealed roads.
The next generation of unsealed roads is to look at an interim or staged approach to unsealed roads where the existing pavement and formation materials are enhanced through stabilisation using conventional binders rather than ‘snake oils’. New design methodologies are being developed based on recent research trials, and the presentation will cover the current results being collected at various trial sites.
