Y1 - 2019/// M1 - master TI - Explaining cost overrun in infrastructure projects UR - https://frw.studenttheses.ub.rug.nl/3126/ N2 - Cost overrun is common among infrastructure projects, and can be a result of different causes. There is a research gap in which configuration of conditions have an effect on cost overrun in public-private partnerships (PPPs). The conditions that will be used to analyze the outcome (cost overrun) are: (1) contract type; (2) type of stakeholder management; (3) proper risk allocation; (4) project size. The research method is a qualitative comparative analysis (QCA). The results indicate that D&C contracts in combination with an improper risk allocation and a relative small project size (between ?120 million and ?410 million) lead to cost overrun. The results also give a solution for cost underrun, consisting of two solution terms. The DBFM contract in combination with process management and a proper risk allocation, and a DBFM contract with a proper risk allocation and a large project size lead to cost underrun. ER -
