The American Society of Civil Engineers claim that corruption accounts for an estimated $340 billion of worldwide construction costs each year. Corruption (including bribery, embezzlement, kickbacks and fraud) in construction projects undermines the delivery of infrastructure services. Furthermore, corruption poses significant risks to construction and engineering companies themselves. What progress has been made, therefore, in reducing the risk of corruption to construction projects? It is the purpose of this paper to argue that with improved accountability, attention to ethics and cultural considerations, and reduced corruption, it is possible to construct, operate and maintain adequate quality and quantity of infrastructure on a more sustainable basis and thereby improve construction practice. This paper will demonstrate how accountability initiatives in construction projects, in developed and developing countries can be of benefit internationally to the public and private sector as well as Non Government Organisations and researchers in their efforts to reduce corruption in infrastructure services.
