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 1987–1988 Anfal Campaign during which the Iraqi Baath regime massacred some 180,000 Kurdish Iraqis, 5,000 of whom killed by chemical weapons in the town of Halabja, is considered one of the major traumas in modern Kurdish history. Yet a few decades later, the Kurds appear to have risen from their proverbial ashes, embarking against great odds on an ambitious state building project in northern Iraq. With this story of "trauma and redemption" as background, this paper considers the lessons learned from this Kurdish experiment; lessons drawn not only by the Kurds themselves, but by all those who willy-nilly accompanied them on this journey; the Iraqi state, the international community, and the United States.

The cost overrun in road construction projects in Iraq is one of the major problems that face the construction of new roads. To enable the concerned government agencies to predict the final cost of roads, the objective this paper suggested is to develop an early cost estimating model for road projects using a support vector machine based on (43) sets of bills of quantity collected in Baghdad city in Iraq. As cost estimates are required at the early stages of a project, consideration was given to the fact that the input data for the support vector machine model could be easily extracted from sketches or the project's scope definition. The data were collected from contracts awarded by the Mayoralty of Baghdad for completed projects between 2010-2013. Mathematical equations were constructed using the Support Vector Machine Algorithm (SMO) technique. An average of accuracy (AA) (99.65%) and coefficient of determination (R²) (97.63%) for the model was achieved by the created prediction equations. [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.

Construction projects are unique in nature. One of its most notable qualities is the length of time that may result in a change of circumstances, resulting in many risks as a result of the long implementation period and the several stages, beginning with the project foundation and ending with final delivery. This raises the level of uncertainty and the probability of risks, which has a negative influence on the economics of construction contracts. To manage risks in such projects, the researcher visited a number of sites in numerous governorates across Iraq after collecting papers and literature on the subject of risk management in construction projects. The researcher prepared unique forms displaying the probability of the risk arising and the magnitude of its effect after extracting a large number of them. After that, the forms were distributed to a group of specialists. Following a statistical analysis of the findings, the researcher came up with a set of conclusions and recommendations for managing risks in Iraqi building projects. [ABSTRACT FROM AUTHOR]
