This chapter’s objective is to demonstrate how uncertainty is managed in the construction phase of road projects. Three aspects of uncertainty management in the construction phase are examined: people and organization, management process, and tools and techniques. The specific importance of the construction phase is based on the fast changes and complexity of this phase. A longitudinal study of seven Norwegian road projects is performed. The projects were all large in terms of cost, each with costs of more than $100 million. Researchers evaluated how uncertainty emerged during the construction phase and how major uncertainties were appraised step by step during construction. In addition, this study contributes to a new recognition of important factors, which influences risk and opportunity management in large road projects by introducing a suggested conceptual framework.

Uncertainties impact a project’s cost, time, and quality performance. The project’s front end is challenging for decision makers due to the high level of uncertainty. This paper identifies the most common uncertainties and their origin in the pre-project phase of large road projects. It also analyses the changes in these factors over 20 years. Document studies collected information about uncertainty factors identified in the early phase of 90 large road projects. The research strategy was explanatory, and data were collected from quality assurance reports from a population of large Norwegian road projects. The project cost varies between USD 30 million and over USD 2 billion. Then, 15-factor groups were established for categorising uncertainties. This study shows a rise in uncertainty factors with operational origins and a decrease in uncertainty factors with strategic and contextual origins over the last 20 yea...

Research on UM has mainly been aimed at uncertainty analyses in the front-end and managing uncertainty in the construction phase. In contrast, UM components in the design phase have received less attention. This research aims to improve knowledge about the key components of UM in the design phase of large road projects.Design/methodology/approachThis study adopted a literature review and case study. The literature review was used to identify relevant criteria for UM. These criteria helped to design the interview guide. Multiple case study research was conducted, and data were collected through document study and interviews with project stakeholders in two road projects. Each case's owners, contractors and consultants were interviewed individually.FindingsThe data analysis obtained helpful information on the involved parties, process and exploit tools and techniques during...

This paper develops a hybrid multiple criteria decision-making model using the fuzzy group analytical hierarchy process (FGAHP) and a modified elimination and choice expressing reality (ELECTRE). ELECTRE is modified to achieve a more appropriate ranking. This hybrid model facilitates the decision-making of managers in real-world cases of science and technology parks investment. Also, to keep AHP capable and efficient in evaluating the large number of alternatives, we analysed the number of pairwise comparisons in uncertain environment using imprecise linguistic criteria. A comprehensive numerical illustration is presented to emphasise the applicability and effectiveness of the proposed hybrid decision-making model.
