The main challenges and barriers facing the effective implementation of risk management (RM) practices in the construction industry have increased the ceiling of challenges associated with the implementation of construction projects during the COVID-19 era. The aim of this paper is to assess the level of significance of risk management implementation challenges and barriers (RMICB) and the level of efficacy of construction RM practices during COVID-19 by considering the case of Iraq. A multistage research methodology was adopted, including semistructured interviews with construction experts to identify the main RMICB and RM practices indicators; surveys to assess the identified RMICB and RM practices indicators; analytical hierarchy process–based and fuzzy-based models to quantify RMICB level of significance, and RM practices level of efficacy. Based on the adopted methodology, the authors identified a total of 34 RMICB grouped under four categories, namely analytical approach–related, behavior-related, management-related, and team-related RMICB. Moreover, the assessment of the current construction RM practices during the COVID-19 era indicated a low level of RM practices efficacy. This study significantly contributes to the body of knowledge by helping construction practitioners and researchers to better understand the RMICB that are hindering effective implementation of RM strategies for construction projects during the COVID-19 era. Furthermore, it provides valuable information to decision-makers regarding the current construction RM practices efficacy during extreme conditions. [ABSTRACT FROM AUTHOR]

The outbreak of COVID-19 has impacted construction markets worldwide due to supply chain disruptions, workforce restrictions, and legislative changes. However, construction markets in developing countries are perceived to be more vulnerable to the challenges associated with the pandemic. As such, the goal of this paper is to capture the impact of COVID-19 on construction projects in developing countries by considering the case of the Iraqi construction sector. A multistep research methodology was adopted by the authors, including (1) literature analysis and semistructured interviews with 40 industry experts to identify a comprehensive list of construction themes and factors affected by the pandemic; (2) survey data collection from 388 industry professionals to quantify the significance and influence of each identified factor; (3) Cronbach's alpha test to check the reliability of the survey; (4) fuzzy inference system to assess the impact of the pandemic on each construction theme and factor; and (5) Mann-Whitney U-test to examine the perceived impact by the public and private sectors. Results show that the pandemic has impacted a total of 16 construction factors grouped under four construction themes, including contractual implications, construction financial market, and supply chain operations, as well as safety and risk management, where the latter is the most impacted theme. The factors impacted the most by the pandemic are safety management measures, interpretation of the contract language, building materials prices, risk management practices, construction materials, construction labor, and construction subcontractors. Also, the findings of the fuzzy model show significant difference in the captured impact of the pandemic between the public and private sectors. This research contributes to the body of knowledge by providing a foothold foundation for researchers and decision makers to enhance investigating the effect of the pandemic with its deep uncertainties in relation to developing countries.
