Aladağ, H and Işık, Z (2019) Design and construction risks in BOT type mega transportation projects. Engineering, Construction and Architectural Management, 26(10), pp. 2223-2242. ISSN 0969-9988
Abstract
Purpose: In build-operate-transfer (BOT) transportation projects, design and construction phases are critical in terms of their effect on time and cost overruns. The purpose of this paper is to identify the role of risk factors affecting these phases and their significance level for BOT transportation projects. Design/methodology/approach: Design and construction risks were determined and then validated by focus group discussions. Afterwards, an illustrated case study was presented to better understand the effects of determined risks in a BOT mega transportation project. As the last step of the study, the fuzzy analytical hierarchy process method was used to prioritize risk factors. Findings: The prominent risk factors were found out as occupational accidents, integration between design and construction phases and excessive design variations. Research limitations/implications: Different kinds of BOT transportation projects in different countries might be executed very differently considering specific social, political, economic and other factors. However, the results of the study are important in terms of the specific lessons learned from the case study that can be used as a foundation for developing possible risk mitigation measures. Originality/value: Though the risk management of BOT projects has been investigated frequently in the literature, there is a knowledge gap in the quantitative evaluation of risk significance specific to design and construction risks. The prioritization of determined risks with an associated case from a mega transportation project will contribute to the BOT project practitioners about possible challenges in design and construction phases in BOT mega transportation projects.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
