8D BIM Model in Urban Rehabilitation Projects: Enhanced Occupational Safety for Temporary Construction Works

Abstract

Building Information Modeling (BIM) is a relevant booster to the modernization of construction. The adoption of digital technologies positively contributes to more agile and integrated processes in all phases of the building life-cycle, namely with regard to project management activities. The implementation of BIM has been predominant in new building projects, but the current market cycle of the rehabilitation or refurbishing of existing buildings offers new opportunities of application to be explored. This paper explores such opportunities, namely with regard to the temporary construction works involved in urban rehabilitation projects with the preservation of the façades of the original buildings. It specifically addresses the impacts of the modeling efforts of steel frames and structures needed to temporarily support façades, after the demolition of the old buildings, and until the original façade is reintegrated into the structural elements of the new building. In a BIM context, an 8D model is created to explore BIM capabilities in enabling more efficient occupation safety and health coordination and management activities in building rehabilitation projects, namely in improving and validating the demolitions and construction methods and sequencing, the scheduling of construction works, and the mandatory occupational risk prevention documents for the construction site. The development of the research was supported on the use of the available BIM software: Revit, to model the façade and the temporary steel structural system; Microsoft Project, to schedule the construction works; Navisworks, to perform clash detection analyses and enable visual simulations for occupational risk, and its identification and mitigation. The study intends to contribute to the dissemination of BIM capabilities to improve occupation safety and health in construction, namely in rehabilitation projects involving temporary structures while contributing with innovative perspectives toward higher maturity in BIM implementation and use in the construction sector.

Digital Technologies in Urban Regeneration: A Systematic Literature Review from the Perspectives of Stakeholders, Scales, and Stages

“…Unlike the preparation stage, oriented toward identification and decision support, the interim stage emphasizes real-time optimization of construction execution, environmental monitoring, and construction scheduling. During implementation, the deep coupling of BIM with three-dimensional technology and Virtual Reality (VR) technology significantly enhances construction efficiency and worker collaboration capabilities, effectively mitigating spatial conflicts and rework risks during construction processes, and achieving shortened construction periods while ensuring construction quality [41,47,48]. In real-time environmental monitoring and construction scheduling, IoT technology and intelligent energy consumption monitoring systems play crucial roles.…”

Collaborative BIM-Based Construction Coordination Progress Modeling Using Extended Collaborative Process Modeling (exCPM)

“…On-site construction coordination can be varied and complex, from onetime to ongoing. Therefore, BIM-based construction coordination does not simply involve implementing nD BIM [9][10][11][12][13][14] or BIM-based clash detection and design validation [41,42].…”

“…Building information modeling (BIM) technology, which is expected to improve the management of construction projects, focuses on achieving the goals of traditional construction projects and related technologies, such as model authoring, using BIM S/W directly related to tangible project deliverables [4], 3D BIM model representation level (e.g., level of development (LOD)) [5], and information exchange, such as the information delivery manual and model view definitions (MVDs) [6][7][8]. Furthermore, 3D BIM is expanding into multidimensional (nD) BIM by fusing concepts, such as schedule, cost, sustainability, facility management, and safety [9][10][11][12][13][14]. However, the techniques suggested by these studies may conflict with existing processes or may not work well when introduced into traditional construction project management methodologies [15].…”
