Investigation of the dispute factors and their effects on construction projects that are arising from Covid-19 Determination of the relations between the dispute factors and their effects using Structural Equation Modeling (SEM) method Identification of approaches that should be applied to reduce the effects of the disputes arising from Covid-19 in construction projectsFigure A. Results of Structural Equation Modeling AnalysisPurpose: The purpose of this study is to investigate the effects of Covid-19 on the construction projects in terms of contractual relations between the parties of construction projects.Theory and Methods: Within the scope of this study, data was collected from a total number of 173 construction projects that were carried out by Turkish construction companies. Then, collected data was analyzed by using Structural Equation Modeling (SEM) method to determinate the relations between the dispute factors and their effects that are arising from Covid-19 as a force majeure factor.Results: Results of the SEM analysis show that "dispute factors arising from contract and claims" affect "project-based dispute factors" whereas "project-based dispute factors" affect "dispute factors arising from financial factors". Key dispute factors to be cognizant of are "progress payments", "failure in claim notifications of contractors within the relevant period following the occurrence of pandemic in written form" and "failure in implementing quality monitoring and control processes due to lack of personnel" with the highest factor loadings in their clusters. Among the effects of dispute factors arising from Covid-19, impact on project duration (time extension) has emerged as the most prominent effect in comparison with cost overruns, termination and suspension of work, and appeal to court/arbitration.
Conclusion:Despite the unforeseen nature of the Covid-19 pandemic, contractors could still be contractually responsible for delays or cost overruns on their current projects in the long term. It is expected that both contractors and owners will be carefully reviewing contracts to identify where contractual rights and duties exist under the conditions caused by the virus' spread. It is recommended that parties review their contracts and take specific note of any force majeure provisions that prevent possible disputes arising from Covid-19. In this context, the results of the study are important in terms of revealing how construction companies are affected in the short term due to Covid-19, as well as in terms of revealing measures that should be considered by construction companies in order to reduce the effects of possible dispute factors that may arise from Covid-19 in their future contracts.
