Health and safety training via immersive virtual reality (VR) in the construction sector is still limited to few early adopters despite the benefits it could provide in terms of training effectiveness. To foster its adoption, in this work, the authors address the lack of an organized asset of digital contents dedicated to the production of VR site scenarios that emerged as one of the most limiting factors for the implementation of building information modeling (BIM) and VR for construction workers’ safety training. To improve this critically time-consuming process, a dedicated site object library is proposed.

The development of the site object library for the production of BIM-based VR safety training experiences followed a four-step process: definition of the object list and categories from the analysis of heterogeneous knowledge sources – construction sectors’ regulations, case studies and site scenarios’ imagery; definition of the object requirements (e.g. information, graphics, sounds, animations and more); design of an object information sheet as a library implementation support tool; and library implementation and validation via collaborative VR sessions.

This work provides the definition of a structured library of construction site objects dedicated to the production of VR scenarios for safety training comprising 168 items, implemented and validated.

The research contributes to facilitate and standardize the time-consuming contents’ production and modeling process of site scenarios for VR safety training, addressing the lack of a dedicated site object library. Furthermore, the novel library framework could serve as a base for future extensions dedicated to other applications of VR site simulations (e.g. constructability analysis).

Building construction is considered a complex, dynamic and highly hazardous process, which embraces many factors that are potentially dangerous to workers. Many studies proved that the improvement of preventive and proactive measures – dynamically included in the building design, planning and construction – could reduce site accidents as well as increase the site productivity. In this context, process management models and information visualization techniques such as building information modeling (BIM) and virtual reality (VR) seem to be devoted to strongly contribute to the advancement of the current safety management practices. For these reasons, the presented contribution is based on the assumption that a more nuanced approach for construction worker's safety training is warranted and the authors propose a safety training protocol based on BIM-enabled VR activity simulations.

The methodology comprised a safety training protocol based on BIM-enabled VR activity simulations. The protocol addresses three methodological issues: (1) Planning in terms of training typologies and related health and safety contents to be implemented in the VR construction site scenarios; (2) Management regarding the solution to integrate BIM and game technologies to deliver VR training experiences; (3) Administration in terms of definition of standardized rules to define a safety training schedule in a given construction project.

This work contributes to provide a standardized protocol for a viable integration of BIM and VR technologies for construction safety training in real projects.

The VR training protocol was applied to a construction project based in Italy that served as case study for the development of the training sessions' contents and their implementation. This case demonstrated the feasibility of the protocol's implementation and pointed out the drawbacks and limitations on which further efforts need to be spent in order to take the proposed protocol from a prototypical stage to a maturity for its larger-scale adoption from the practitioners involved in construction safety training.

The research gives a contribution to reduce the currently existing knowledge gap regarding how BIM and VR can be simultaneously integrated in real projects for construction safety training by using standardized rules to be extensively reproduced in different construction projects. It uses a customized toolkit with a mobile smartphone solution to administer Safety Training Scenarios which increases its portability in construction site compared to PC-based VR solutions.

This paper aims to highlight the factors affecting health and safety (H&S) and the SMART Technologies (ST) used to mitigate them in the construction industry through a range of selected papers to encourage readers and potential audiences to consider the need for intelligent technologies to minimize the risks of injuries, illnesses and severe harm in the construction industry.

This paper adopts a double systematic literature review (SLR) to analyse studies investigating the factors affecting H&S and the ST in the construction industry using databases such as Google Scholar, Scopus, Science Direct and Emerald Insight publication.

The SLR identified “fatal or focus five factors” that include objects Fall from heights (FFH) and trapped between objects; Falls, Trips and slips (FTS); Machinery/Equipment Malfunction and Moving Equipment; Pollutants: Chemicals, Airborne Dust, Asbestos; and Electrocution. The ST includes Safety Boots/SMART Glasses/SMART Helmet/SMART Vests/SMART PPE/SMART Watch, Mobile Apps, Building Information Modelling (BIM), Virtual Reality/Augmented Reality (VR/AR), Drones/Unmanned Aerial Vehicles and Wearable Technology/Mobile Sensors help mitigate the risk posed by “Fatal five”. However, other factors within the scope of ST, such as Weather Conditions, Vibrations, Violence, Disease and illness, Fire and Explosion and Over Exertion, are yet to be adopted in the field.

SLR methodology limitations of not obtaining the most updated field knowledge are critical and are offset by choosing 72% of H&S and 92% of SM review literature post-2017. Limitations to capturing articles because of the restriction of database access: only English language search and journals that are not a part of the databases selected are acknowledged. However, key database search that recognizes rigorous peer-reviewed articles offset these limitations. The researcher’s Bias is acknowledged.

This paper unravels the construction H&S factors and their interlinks with ST, which would aid industry understanding and focus on mitigating associated risks. The paper highlights the Fatal five and trivial 15, which would help better understand the causes of the H&S risks. Further, the paper discusses ST’s connectivity, which would aid the organization’s overall H&S management. The practical and theoretical implications include a better understanding of all factors that affect H&S and ST available to help mitigate concerns. The operating managers could use the ST to reduce H&S risks at every construction process stage. This paper on H&S and ST and relationships can theorize that the construction industry is more likely to identify clear root causes of H&S and ST usage than previously. The theoretical implications include enhanced understanding for academics on H&S factors, ST and gaps in ST concerning H&S, which can be expanded to provide new insights into existing knowledge.

This paper highlights all factors affecting H&S and ST that help mitigate associated risks and identifies the “Fatal five” factors. The paper is the first to highlight the factors affecting H&S combined with ST in use and their interactions. The paper also identified factors within the ST scope that are yet to be explored.
