Abstract

Hybrid infrastructure projects are defined as triads of on-site/coordination/off-site project dimensions. Interaction of uncertainties in such settings result in deviations from project objectives by causing time and cost overruns, safety issues, quality deficiencies, technical problems, and lack of client satisfaction. To address these, a holistic approach in identifying and analyzing risks in hybrid (multi-dimensional) projects is proposed. Towards this aim, three research hypotheses are developed and tested using data from seven projects in Melbourne, Perth and Adelaide, Australia. Practical implications of triadic risk analysis in hybrid infrastructure projects suggest executives and managers to put more emphasis on risks associated with coordination of on-site and off-site project dimensions. This approach significantly decreases the chance of deviations from project objectives.

6. Conclusions

Previous research has investigated uncertainty and its effect on objectives in infrastructure projects (Chan and Au, 2007; Espinoza, 2014). With increasing use of prefabrication, such projects are transitioning to a hybrid of site-built and off-site activities with significant coordination efforts (Li and Taylor, 2014). Therefore, an integrated risk management approach is required to model and analyze uncertainty in hybrid projects. Towards this aim, the current research developed and tested three hypotheses on dynamics of risk analysis in hybrid project settings. The findings show that risks associated with coordination of on-site and off-site project dimensions are believed to be the most significant contributors to deviations from project objectives. The findings are applicable and generalizable to many project settings with division of work and labor where substantial coordination/communication is required.
