“…Both include 3D visual representations of building elements, and construction schedules can be connected with model elements in both technology types, but elements in 4D CAD lack additional parametric information. Mallasi (2006) has used 4D CAD to identify and minimize workspace congestion between construction activities' execution space. In his research, he developed a methodology and a tool to assist planners with the assignment of activities' execution space, as well as identification and visualization of workspace congestion.…”

Abstract Construction industry is one of the most hazardous industries to work in. This problem is further exacerbated by the fact that safety performance improvement is stagnating. Information technologies (ITs) are however identified as one of the most promising methods of improving the performance of construction safety. The goal of this paper was therefore to present previous research in the application of innovative ITs to the field of construction health and safety (H&S), classified by their underlying technology and application, to identify research gaps, as well as to evaluate and describe the potential of their implementation into construction safety practice. To achieve the set goals, the research consisted of identifying and studying the existing research published in the leading journals in the field of construction H&S. The review identified 72 papers dealing with development or application of innovative ITs. The research had also identified several research gaps, which have a significant impact on the construction safety practice. These gaps focus on the construction phase, while neglecting earlier project phases; industry and project levels, while neglecting construction activity and task levels; building projects, while neglecting infrastructure projects and specific hazard types, while neglecting a universal approach. Focussing research effort on these gaps would benefit all construction safety stakeholders but mostly the prominent contractors and H&S professionals. Furthermore, recommendations for directing research focus on solving the identified issues are given in this paper.

“…Mallasi [41] Advantages of the rule-based 4D safety system on a project include abilities to identify working-at-height hazards according to the progress of the construction project; to discover different building components with the hazards at their own placements; to give safety measure advice; to integrate safety measures into the construction schedule; to enable people to reveal problems in the original design and schedule; and to support control of safety measures. Nevertheless, the limitation of this research using an automated approach is that a hard-coded algorithm is closed, and cannot make complex design decisions that need human creativity or knowledge to be involved in some circumstances.…”

As digital technologies become widely used in designing buildings and infrastructure, questions arise about their impacts on construction safety. This review explores relationships between construction safety and digital design practices with the aim of fostering and directing further research. It surveys state-of-the-art research on databases, virtual reality, geographic information systems, 4D CAD, building information modeling and sensing technologies, finding various digital tools for addressing safety issues in the construction phase, but few tools to support design for construction safety. It also considers a literature on safety critical, digital and design practices that raises a general concern about 'mindlessness' in the use of technologies, and has implications for the emerging research agenda around construction safety and digital design. Bringing these strands of literature together suggests new kinds of interventions, such as the development of tools and processes for using digital models to promote mindfulness through multi-party collaboration on safety.

“…Currently, there are two directions in dealing with spatial conflicts. The first direction is to create a schedule which eliminates all potential spatial congestions (Jongeling and Olofsson 2007;Zhang et al 2007;Elmahdi, Wu, and Bargstädt 2011); and the second direction is to adjust a schedule to minimize congestion (Mallasi 2006;Winch and North 2006;Bansal 2011). Application of a conflict-free method, which follows the first direction mentioned above, for lookahead planning may be not feasible.…”

In order to improve the flexibility and adaptability of an automated model to various different projects under different circumstances, various solutions should be generated as proposed results, instead of only one solution as in recent research. This paper therefore presents a method for generating a series of reasonably detailed schedules for mapping the workplaces of activities over time. This model incorporates Pareto-based optimization and simulation. The optimization engine takes on the role for generating and choosing good schedules. The simulators, on the other hand, are responsible for manipulating activities to resolve spatial conflicts, to respect the limits of crews and investigate the efficiency of solutions. A prototype implementation is afterwards developed and implemented in software based on Building Information Modeling, which enables the model to automatically retrieve the required geometric data. The output solutions are finally analyzed through an example to prove their feasibility and adaptability to various potential situations.
