Modular Integrated Construction (MiC) is a rapid and sustainable solution for construction projects. However, it poses challenges in crane safety operations (CSO). This paper examines CSO in MiC, offering fresh perspectives and contributions. The research aims to identify patterns, knowledge gaps, and future directions in CSO within MiC. Scientometric and systematic review approaches are integrated to ensure a comprehensive analysis. CSO research is categorized into four primary problem-based categories: Crane-Related Fatalities, Accidents, and Hazards; Risk Analysis and Evaluation; Enhancing Lifting Process Efficiency and Crane Operator Safety; and Technological Solutions and Innovations. Each category is subdivided into methods-based subcategories. The paper provides insights into methodologies and global trends in CSO practices, facilitating safety improvements in MiC projects. It also outlines future research directions and practical recommendations for implementing strategies aligned with these directions. This paper serves as a catalyst for enhancing safety and implementing research findings in real-world MiC scenarios. [Display omitted] • MiC offers rapid, efficient construction but poses unique challenges, notably in CSO. • MiC's CSO research growth prompts pattern detection and gap analysis. • A mixed review method blends scientometrics and systematic reviews CSO in MiC. • Four problem-based categories: fatalities, risk, lifting, and technology. • The systematic review identifies five gaps and outlines future research opportunities.

Modular integrated construction (MiC) is evoking interest as a sustainable construction method leading towards industry 4.0. However, its complex supply chain and fragile logistic operations impede project performance. This paper, therefore, explores the critical influencing factors of MiC supply chain operations and studies their interrelationships. A systematic review is conducted across multiple supply chain research domains to identify relevant factors. These factors are evaluated using eigenvector and MICMAC analysis. Four themes of critical factors are determined using factor's interrelationships: dominating, symbiotic, external, and potential influencing factors. These themes demonstrate the influencing nature and mechanism of factors. As a result, most of the assembling-related factors are found to dominate and dynamically control the MiC supply chain performance. This paper also highlights potential factors that need further research attention, studies prevalent factors affecting the MiC supply chain and offers future research directions. [Display omitted] • General supply chain management, logistics management and construction supply chain domains are systematically reviewed. • Forty-three significant factors were ranked using eigenvector approach. • Critical factors are evaluated and categorized using MICMAC analysis. • Factors' relationships are analysed, and four themes of factors are determined. • Paper studies prevalent factors affecting MiC supply chain and highlights potential factors that need further research.

Off-site construction (OSC) is an innovative and sustainable construction method. One of its critical success factors is the proper management of its supply chain (SC). Recently, significant research attention has been focused on the modelling of OSC-SC to improve its performance and sustainability. However, the literature still lacks a comprehensive review of the modelling studies on off-site construction -supply chain management (OSC-SCM). Therefore, this research contributes by providing a comprehensive and up-to-date mapping and clustering of 309 journal articles on the modelling of OSC-SC to identify its trends and gaps, and hence, highlight future research opportunities. To achieve these objectives, a mixed review method, consisting of scientometric and systematic reviews, is used. The scientometric review identifies the most prolific journals, researchers, co-occurrence network of keywords, and their citation bursts. On the other hand, the systematic review classifies the articles based on OSC type and supply chain (SC) stage. At each SC stage, the articles are further classified based on problem settings and solution methods. The results show that production problems have received the most attention (i.e., by 28% of the included articles), followed by on-site construction (19%), design (13%), and logistics (7%) problems. However, researchers are more inclined to address problems at multiple SC stages (33%) due to the interrelationship between these stages. Besides, the systematic analysis shows that OSC-SC problems have been solved frequently by a variety of solution methods such as optimization (25%), simulation (13%) and building information modelling (BIM) (9.5%). However, researchers tend more to integrate multiple solution methods (35%) to address the complexities of OSC-SC problems. Finally, the included studies are classified based on the three sustainability dimensions. The results show that economic, environmental, and social sustainability dimensions have been considered in previous studies by 72%, 24%, and 4%, respectively. Therefore, the study identifies research gaps at each SC stage of each OSC type to incentivize future studies to consider more environmental and social sustainability factors in OSC-SC models. Since modular integrated construction (MiC) has the highest prefabrication level, this study provides future research directions for sustainable supply chain management (SCM) in MiC. The present research is an important reference guide that helps researchers and practitioners to understand different problem settings and their solution methods in OSC-SCM.
