Benchmarking Cost Overruns in Transportation Infrastructure Investments
Abstract: Highway projects have historically experienced significant cost overruns, with front end implications for the sustainability of transportation investments. However, the criteria for assessing cost overruns continues to elicit diverse opinions and has become a debatable issue in the literature. Some studies allude to detailed design stage estimates, while others tag conceptual stage estimates, as the ideal benchmark for quantifying the project cost deviations. A survey of the literature, principally from …

Towards a Geo-Classification of the Niger Delta for Highway Investment Costing Applications
Abstract: The study carries out a quasi-experimentation, as a basis of devising a spatial quantitative concept, delineating distinct geologic settings which would have differing cost implications for highway infrastructure development in the Niger Delta region of Nigeria. Three broad conceptual geomorphic boundaries, for the categorisation of Niger Delta soils in engineering geologic costing application, were discerned within this conceptual lens. The study further statistically explores the synthesised geo-zonation for differences in …

Explaining the Cost Performance and Maturity of Transportation Infrastructure in the Developed and Developing World: One Size Fits All?
Abstract: AbstractScholarly text analysing the financial performance of highway projects are evident in the literature, most of which have opined that highway agencies record higher levels of cost overruns compared to other clients of construction and building works. Similar assertions are made about the relatively higher levels of cost overruns recorded on highway projects executed in the developing world. A scant number of seminal works have emerged in the literature, offering …
