During the last several decades, behavior-based safety (BBS) has drawn a considerable amount of attention in construction industry. The focus BBS is on improving workers' behavior through feedback and increased self-awareness motivation. Among influencing factors behavior, social norm known to be powerful mechanism that regulates behavior. However, it unclear how norms are developed which process influence an individual worker's projects. Additionally, temporary contract-based nature...

Recently, formal approaches to interface management (IM) have been adopted in a number of large-scale engineering and construction (E&C) projects. However, understanding the role performance IM practices E&C projects is quite limited today. Given this circumstance, paper attempts understand effectiveness from perspective dealing with project complexity. To fulfill objective, data on complexity were collected 45 analyzed using quantitative analysis methods such as principal component linear...

Many researchers, as well industry practitioners, believe that offsite construction methods are associated with a lower level of worker safety risks than traditional onsite methods. This study aims to test such belief by comparing the list identified site supervisors for both and scenarios same building components. Specifically, Safe Work Method Statements (SWMS)—prejob hazard assessments required law in Australia—were collected from two projects where manufacturing has been used, they were...

Immersive virtual reality (VR)–based training has been widely proposed in different firms to improve the hazard recognition skills of their workforce and change unsafe behavior. However, little is known about impact VR-based on user’s behavior learning. With use structural equation modeling (SEM), this study investigated 60 participants, results supported mediating effect VR system features users’ acquisition knowledge, behavioral intention, satisfaction. The also indicated that were a...

Understanding the causal relationships between safety management system (SMS) factors and accident precursors helps construction organizations identify which require improvement upon observing an precursor. Previous research has not clearly distinguished SMS precursors. This background examines using empirical data. Specifically, five structural equation models (SEMs) were developed to map paths Each of SEMs what specific would have a significant influence on occurrence particular type These...

Although many construction organizations have recently adopted mobile information and communication technologies (ICT) such as smartphones tablets to support project management activities, it has not been clear what drives the adoption of ICT kinds real benefits are provided by use in context management. Against this background, present study aims empirically investigate main consequences how can ultimately affect productivity. An exploratory factor analysis based on survey data collected...

Safety training is an effective method to reduce safety issues. Immersive virtual reality (IVR) for has gained attention in high-risk industries, but the trade-off between realism and abstraction IVR-based not fully understood. This study investigated impact of scenario interaction fidelity on forklift training, focusing presence usability. Scenario varied Level Development (LOD) IVR model (high LOD vs. low LOD), while control interface (steering wheel pedals keyboard). A 2-by-2 experiment...

Workers' consistent attendance is an indispensable condition for successful construction projects, but many projects still suffer from the productivity loss originating workers' absenteeism. To deal with this problem, managers have mainly used formal controls (e.g., penalties) targeting those individuals who present excessive However, recent research papers on absenteeism testified to paramount role of social factors, such as norm, absence behavior. Despite increasing attention being paid...

The performance of a safety management system (SMS) is influenced by large number internal and external factors. Loss control these factors can create unsafe conditions, which eventually lead to worksite accidents. Identification prioritization crucial for optimal SMS performance. However, because the complex dynamic nature accident occurrence, identification critical precursors remains difficult in practice. This paper proposes use risk-rating approach understanding complexity between from...

Interface management (IM) is an emerging construction practice that industry finds necessary for megaprojects have become more complex and global. Defined as the appropriate of communications, relationships, deliverables among stakeholders, effective IM integral to project success. Yet, because it discipline, implementation has varied widely across industry. Furthermore, effect on performance still unclear. To address these gaps, institute (CII) chartered a research team, identify current...

Abstract Although offsite construction (OSC) has emerged as a promising solution to low productivity issues in the industry, knowledge for effective management of OSC projects is yet be explored and developed further. To enhance our understanding landscape current knowledge, this study identified reviewed 83 operation-level papers. By mapping papers on three dimensions (i.e. project type, phase, area), review sheds light areas addressed more frequently than other over time detailed manner....

This paper analyzed 19 precast concrete (PC) construction project cases from Korea using fuzzy-set qualitative comparative analysis to explore the relationship between conditions of PC projects, observable at an early stage and actual schedule delays. The following combinations leading delays were identified: (1) use multiple types components nonuse building information modeling (BIM) for management; (2) included in critical path, insufficient experience contractor BIM (3) nonresidential...

Because construction operations depend on labor activity, absenteeism a job site can damage project performance in many ways. Traditionally, managers have viewed as problem of individuals and not paid much attention to group-level phenomenon. As result, individually focused formal rule enforcement (e.g., issuing penalty) has been used reduce projects, but this approach often results the insufficient encouragement attendance motivation. To better manage workers' sites, another aspect that...

Construction workers’ attitudes and behaviors are one of the most important factors a construction project’s performance. As attention paid to impact social influences norms on worker behavior grows, agent-based modeling simulation (ABMS) emerges as research tool for studying group behavior. With ABMS, researchers can uncover underlying process emerging from individuals’ interactions in an organization. However, validating with real data is greatest challenge using ABMS organizational...

With the purpose of reducing amount construction and demolition (C&D) waste disposed to landfills, many countries municipalities have introduced increasingly stringent C&D disposal charges (CDWDC) but level CDWDC is often determined without a clear understanding its broad complex impacts. Against this background, paper aims propose system dynamics (SD) model that can help predict CDWDC’s environmental implications as well financial implications. Specifically, proposed explains causal...

Many construction accidents are caused by workers' unsafe behavior, and evidence suggests that individuals who not sensitive to risks accident-prone. Therefore, identifying workers with certain personal characteristics related habitual insensitive response safety potentially can help managers develop individualized training interventions. Although the methods which could identify those specific have been limited, wearable sensors provide an opportunity for monitor individual behavior without...
