Identification and Prioritization of Critical Risk Factors of Commercial and Recreational Complex Building Projects: A Delphi Study Using the TOPSIS Method

Abstract

Construction development of Commercial and Recreational Complex Building Projects (CRCBPs) is one of the community needs of many developing countries. Since the implementation of these projects is usually very costly, identifying and evaluating their Critical Risk Factors (CRFs) are of significant importance. Therefore, the current study aims to identify and prioritize CRFs of CRCBPs in the Iranian context. A descriptive-survey method was used in this research; the statistical population, selected based on the purposive sampling method, includes 30 construction experts with hands-on experience in CRCBPs. A questionnaire related to the risk identification stage was developed based on a detailed study of the research literature and also using the Delphi survey method; 82 various risks were finally identified. In order to confirm the opinions of experts in identifying the potential risks, Kendall’s coefficient of concordance was used. In the first stage of data analysis, qualitative evaluation was performed by calculating the severity of risk effect and determining the cumulative risk index, based on which 25 CRFs of CRCBPs were identified for more accurate evaluation. At this stage, the identified CRFs were evaluated based on multi-criteria decision-making techniques and using the TOPSIS technique. Results show that the ten CRFs of CRCBPs are external threats from international relations, exchange rate changes, bank interest rate fluctuations, traffic licenses, access to skilled labor, changes in regional regulations, the condition of adjacent buildings, fluctuations and changes in inflation, failure to select a suitable and qualified consultant, and employer’s previous experiences and records. Obviously, the current study’s results and findings can be considered by CRCBPs in both the private and public sectors for proper effective risk identification, evaluation, and mitigation.

Perceptions of Safety Climate in Construction Projects between Workers and Managers/Supervisors in the Developing Country of Iran

“…Risk refers to the exposure to a hazard (risk factor). Thus, safety is an antonym for risk and aims to eliminate the actual risks present at the worksite [19][20][21][22]. Safety also seeks to prevent the impact of agents that minimize the expected quality of the product or offset the result of the work, thus wasting the efforts made to realize something [23].…”

Identifying and Evaluating the Essential Factors Affecting the Incidence of Site Accidents Caused by Human Errors in Industrial Parks Construction Projects

“…Then, the SWARA method was used to prioritize the identified factors. In this study, the purposeful sampling method was used to select the respondents to the survey, which was conducted by other researchers for similar research questions [ 11 ]. According to the subject of the study, the statistical population includes 220 engineers and construction management specialists, insurance experts, and HSE experts of industrial park company.…”

“…Occupational accidents have killed more than 300,000 people and injured more than 300 million worldwide each year [ 10 ]. According to researchers, the cost of occupational accidents in the construction industry may be up to 15% of the total cost [ 11 ]. Workplace safety is a major concern in many countries.…”

Assessment Quality Risk Factors During the Construction Phase of the Biconsi Tower Project

“…Construction projects have always been exposed to various unforeseeable risks, particularly during the construction phase of office projects. The following table summarizes ten critical quality risk factors of the Biconsi Tower project in Vietnam based on a survey of research publications and in-depth expert interviews (Arumsari et al, 2018;Dehdasht et al, 2017;Do et al, 2017;El-Sayegh & Mansour, 2015;Eybpoosh et al, 2011;Gan et al, 2017;Hussain et al, 2019;Kassem et al, 2020;Likhitruangsilp & Ioannou, 2009Likhitruangsilp et al, 2016;Liu et al, 2017;Naderpour et al, 2019;Nguyen & Nguyen, 2020;Nguyen et al, 2021;Perrenoud et al, 2016;Rustom & Amer, 2006;Siraj & Fayek, 2019;Subramanyan et al, 2012;Tadayon et al, 2012;Tamošaitienė et al, 2021;Viswanathan et al, 2020;Xu et al, 2010;Zavadskas et al, 2010;Zeng et al, 2007;Zou & Zhang, 2009)…”
