“…This might be the result of confidentiality terms and conditions of the project contract. However, it is very important to reinforce SIAC research because safety investment positively impacts project performance with reduced accident cost, enhanced productivity and reputation (Zhang et al , 2021).…”

PurposeConstruction safety management (CSM) has been intensively researched in the last four decades but hitherto mostly aimed at understanding root causes of accidents, recommending preventive measures and evaluating their implications. However, a systematic effort to present a comprehensive picture of construction safety research is hardly witnessed. Therefore, the study aims to investigate construction safety research contributors, ontologies, themes, evolution, emerging trends and future directions using quantitative and qualitative content analysis.Design/methodology/approachA total of 877 journal articles were extracted using preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines and Scopus literature database and were analyzed using VOSviewer and Nvivo tools to present a comprehensive picture of the CSM body of knowledge.FindingsThe study observed rapid growth in construction safety research with contributions from various countries, organizations and researchers. This study identified 3 research levels, 8 project phases, 10 project types, 6 research instruments and 19 research data sources along with their usage in the research domain. Further, the study identified 13 emerging research themes, 4 emerging research trends and an observed paradigm shift from reactive to proactive CSM approach.Research limitations/implicationsThe comprehensive study on the emerging themes and findings on proactive CSM has strategic implications to practice to incorporate safety. The identified future directions can assist researchers in bridging the existing gaps and strengthening emerging research trends.Originality/valueThe study presents a comprehensive picture of the CSM body of knowledge using the content analysis approach that was absent in past literature and opened future research avenues.

“…On the other hand, Zhang (2018) highlighted the limitations of multi-criteria feasibility evaluations in High-Speed Rail projects in the US. Other research (Zhang et al, 2021;Boadu et al, 2020) identified the critical factors influencing the safety of Chinese subway construction projects that are directly related to construction projects feasibility. Fedorova (2019) indicated that feasibility and socio-economic studies of mega infrastructure projects such as rail and metro networks are crucial for sustainable planning of different construction activities of such projects.…”

Purpose This paper aimed to study the optimal way to implement and subsequently manage the new metropolitan lines in the Kuwait city as well as to justify them from a social and economic-financial viability standpoint and the most important aspects of transport infrastructure projects viability. The implementation of new modes of transport in an urban environment requires the study of several factors that allow their incorporation on the transport system in the most efficient method. These factors include reviewing the organization of the transport system. The concept of transport system organization, financing models and common trends was defined. Finally, the Public Transport Authority was created to define global objectives and establish specific policies to achieve them was suggested.Design/methodology/approach After the analysis of the “status quo” of transport systems organization, the financing and management schemes, both infrastructure projects and the provision of rail service were analysed. The characteristics of the PPP scheme (Public–Private Participation) contract, advantages and disadvantages, its structure, and the definition and share of risk (matrix of risk, rights and obligations of the parties) as a key element of the PPP contracts were defined. From this point onwards, the legal framework in force in Kuwait was analysed, particularly the administrative and commercial regulations applying to this project and the authors verified that the economic-financial viability analysis suggested before can be established under this framework.Findings For the viability of these alternatives, the authors developed a simulation economic-financial model that reflects Financial Statements for the “Society Vehicle Project” and are considered some minimum thresholds of profitability, both from the viewpoint of the partners sponsoring the project as from the standpoint of lenders, which make attractive participation of private initiative. Finally, there was a short socio-economic analysis to justify the project implementation from a social standpoint. It analyses and quantifies the reduction of operating expenses of other modes of transport, travelling times, accident rates, environmental pollution etc. All these factors affect the quality of life of the population of Kuwait and are the main reason to carry out this project. Several recommendations were raised that aimed at preparing the projects, bidding and selection of private partner and the articulation and implementation of projects.Originality/value This research contributes to the existing body of knowledge through setting the framework for metro projects in arid regions with the hottest temperature on Earth such as Kuwait where such projects are missing completely. This work will be very helpful to governments and municipalities in taking investment decisions. It sets the strategy for utilizing the best of decision-making theory, identifying the reliability advantages and finding the larger economic effects. This work identified, through the analysis of alternative management options generally used in underground and rail projects in different parts of the world, the most convenient alternative in developing countries. It also clearly showed, through the analysis carried out on governmental contributions, how to obtain economic viability for such types of projects. Finally, it helped drawing a roadmap for preparing the projects, bidding and selection of private partner and the articulation and implementation of projects in Kuwait and Gulf Cooperation Countries (GCC).

“…Therefore, the safety level of contractors and subcontractors could directly affect the PSL (Imriyas, 2009). Furthermore, Zhang et al (2020) identified contractor-related factors as a primary variable influencing safety in subway construction projects.…”

PurposeThis study aimed to explain how a framework could be developed for (1) the preliminary estimation of project safety level (PSL) in current projects, (2) the estimation of the maximum possible PSL using limited financial resources and (3) the estimation of the minimum financial resources required for reaching a specific PSL.Design/methodology/approachThe data of 95 steel structural building projects were collected via a questionnaire to evaluate the proposed framework for the Iranian construction industry. Based on unofficial local construction statistics and literature reviews, six safety influential factors (SIFs) were selected to which a cost could be assigned. The costs associated with various levels were also determined for each SIF through literature reviews and expert interviews. A multiple linear regression (MLR) model was developed as a predictive model to determine PSL for future projects based on the data of previous projects. Moreover, linear programming (LP) was applied to take modeling constraints and project conditions into account.FindingsThe results demonstrated the impacts of all the factors on PSL and the model's potential for the preliminary estimation of PSL using SIFs. The results also indicated that a higher PSL could be achieved by optimizing the allocation of financial resources to each SIF.Originality/valueThis study contributes to the existing body of knowledge by developing a step-by-step framework to identify an optimal safety cost allocation (OSCA) to achieve the maximum possible PSL using a limited safety budget and considering the data of similar projects. The main objective was to promote project safety, decrease construction site injuries and fatalities and help local construction industries exploit potential financial advantages.
