Purpose: The general aim of the study was to investigate the implementation of risk management in the construction industry in Libya. Theoretical framework: The role of risk management in project management in the construction industry in Libya is described in this paper. The study involved more than three hundred construction companies located in Tripoli and Benghazi as these are two main cities in Libya where construction was most active and involved big projects and large investment. Design/methodology/approach: Questionnaires which were designed based on cluster sampling were sent to respondents i.e., basically the company managers and 250 replies were obtained. Structured equation modelling was used to analysis the information by Smart-PLS program. The risk management processes defined by identification, assessment and monitoring which contributed to the project success was also related to the financial risk. Findings: The study found that risk management practices had substantial and favourable effects on the success of the project's execution. Further the awareness of quality management in terms of risks was most encouraging. Research, Practical & Social implications: The current findings of this research have shown that most studies focus on the effect of risk management practices as strong tool to improve the project performance. A productivity survey might give a better overview of risk management at other sectors as it concerns the actual output of the construction companies. Originality/value: The systematic literature review approach was hardly found in study of risk management and project performance. At the same time, the exploratory method was applied to synthesize previous studies on risk management and project performance in construction companies.

PurposeThe purpose of this paper is to provide insights into the environment, resources and surroundings factors to develop a system dynamic model of dynamic project scheduling that aids on-time project delivery by reducing the project delay for the road construction industry in New Zealand (NZ).Design/methodology/approachThis study adopted narrative inquiry methodology that involved semi-structured interviews (SSI)/expert opinion and systematic literature review (SLR) data to determine the environment, resources and surroundings factors to develop a system dynamic model of dynamic project scheduling that aids on-time project delivery by reducing the project delay for the road construction industry in NZ. The data were analysed by using descriptive analysis, Likert scale and thematic analysis techniques to understand the relationship of these factors to propose a system dynamic model.FindingsThis study concludes that weather, pandemic, material, geotechnical and disaster factors highly influence while other factors such as equipment shortage, breakdown, design error, labour and event had mixed impact on the dynamic scheduling (DS) that aids on-time project delivery. The proposed system dynamic model can enhance the understanding of factors affecting DS.Research limitations/implicationsSLR is limited to English literature. The limitations of an SSI and a small sample size are acknowledged.Practical implicationsThe proposed model can reduce the uncertainty and scheduling errors during the planning phase and aid in the lesser scheduling modification during the execution phase. In practice, this study will be helpful for road contractors to understand environment, surroundings and resource in-control and out-of-control factors, overcome road construction delays, reduce cost, aid in stakeholder management and sustainable development.Social implicationsThe inclusion of environment, resource and surroundings factors in force majeure clauses will bring an understanding between contracting parties and in turn reduce disputes and delays and help social causes such as on-time infrastructure delivery.Originality/valueFor the first time in a road construction, dynamic project scheduling model that collectively included and linked environment, resource, and surroundings factors to determine the in-control and out-of-control factors for an organisation is proposed. The novelty in the paper is provided by the inclusion of the events, disasters, and pandemics influence on DS in the NZ road construction industry for the first time.

Many road construction projects often go over budget. Take longer than expected. This research focuses on pinpointing the reasons, for delays and cost increases in road construction ventures in Libya. A survey was conducted with owners, consultants and contractors involved in road projects in Libya resulting in 163 completed questionnaires being analyzed. The study examined 55 factors identified through literature review. Improper planning emerged as the factor leading to project delays and cost overruns in road projects. Respondents ranked factors based on their impact with the top five issues being lack of experience with contracts, political instability, unrealistic contract durations and insufficient details and specifications. The insights gained from this study can aid all parties involved in construction projects to better handle delays and cost overruns. Researchers focusing on delay causes and cost escalations, in developing countries within the realm of road construction can also benefit from these findings.
