Road networks represent a significant asset to governments in Australia and New Zealand. In Queensland the state controlled road network consists of some 33 000 km of road which contains around 2850 bridges and many thousands of culverts. The replacement value of these bridges and culverts is around $3 billion. Analysis of life cycle costs, including costs of replacement, show that long life structures (300 years) are the most economical in almost all cases. Investigations by Carse (2003) have found that the majority of Queensland`s concrete bridges typically require maintenance at a life of 50 years, with probably only about 1% of these structures reaching a 100 year design life without significant maintenance. Along with this apparent lack of durability in bridge and transport infrastructure, Australian and New Zealand Road Authorities are becoming increasingly frustrated with issues relating to quality in the construction of bridges and other transport infrastructure. Recent major projects, and benchmark studies have highlighted significant problems with construction quality. Systems and people, along with appropriate technology are intrinsic to the achievement of quality and simple reliance on other parties QA systems will not ensure that a quality product is delivered. This is because there are a number of phases involved in a typical bridge construction contract and also multiple parties whose quality systems need to inter-relate during the construction period. An understanding of current and emerging materials technology is also critical in achieving long life durable structures. This report discusses the importance of quality and durability in the construction of bridge and other transport infrastructure. Issues essential to achieving specified quality in construction from an Owner or Road Authority`s perspective are discussed and the basis for a set of guidelines for achieving specified quality in construction is presented.
