AbstractIn many developing economies construction investments account for almost half of all the other investments. Therefore the effects of cost overruns are not confined to the construction industry but are reflected in the state of the overall economy of a country. The research study was undertaken to investigate ยท the extent and causes of cost overruns in infrastructure projects in Sri Lanka. By conducting a survey of 19 infrastructure projects and 11 building projects it was found that during 1995 - 1998 the extent of cost overruns in infrastructure projects was significantly high in Sri Lanka. Road projects recorded cost overruns of 60% and water supply projects 44%. Comparing with studies done elsewhere on project cost overruns found that infrastructure projects presented very high cost overrun figures. In a bid to further analyse the causes of cost overruns phenomena in infrastructure projects another independent survey was conducted to determine the different views among senior executives in contracting and consulting companies involved in infrastructure projects. The significance level of contractors' and consultants' perspectives were rated on twelve causes for cost overruns identified from previous studies and author's own experience. It was found that both contractors and consultants agreed on "inadequate site investigations" as a significant cause for cost overruns. Hence sufficient time should be devoted on pre-contract planning to minimise cost overruns irrespective of political or other short-term considerations. Contractors claimed that most of the materials specified in infrastructure projects turned out to be very expensive and are not appropriate for use in the Sri Lankan context and cause very high construction costs. However very few consultants agreed to that and the few who agreed put the blame on foreign consultants for inappropriate specifications. Recommendations were focused on minimising the acute cost overrun problem in infrastructure projects and they were based on causes of cost overruns and construction contract types. A major recommendation was to improve coordination among all parties to the contract to minimise cost overruns. Complex infrastructure projects in Sri Lanka should therefore move away from traditional contract types to construction management and management contracting types to minimise cost overruns as they ensure proper coordination and contractor involvement from the design stage itself. Finally the study suggests that the Government should promote more private sector participation in infrastructure projects as they transfer the burden of cost overruns on to the developer and it resolves the acute cost overruns problem, due to commercial considerations of developers. The findings of the study should be of interest for most of the developing economies that are engaged in expanding the infrastructure of their countries.
