An Integrated 5D Tool for Quantification of Construction Process Emissions and Accident Identification

Abstract

-The environmental and safety performance of construction sites are increasingly regarded as critical factors that need to be monitored for the successful completion of construction projects. Research has also repeatedly highlighted the need to minimise the carbon footprint of the construction process and enhance the capacity of the project team and on-site workers in detecting and avoiding potential construction site hazards. However, a multi-dimensional visualisation technology that would allow project teams to simulate potential carbon emissions from construction plant and equipment and to detect potentially 'dangerous' locations on a construction site is currently lacking. This paper illustrates an integrated 5D model that uses virtual prototyping technologies to quantify carbon emissions, simulate the pattern of emissions from the overall construction process and identify potential 'black spots' of site hazards at the planning stage. The proposed 5D BIM based pro-active construction management system (PCMS) can help to detect potential sources of danger to on-site workers and provides pro-active warnings to prevent fatal accidents caused by falling or being struck by moving objects. A public housing project developed by the Hong Kong Housing Authority is used as a case study to demonstrate the integration of the emission prediction visualisation and accident detection tool into the BIM. The proposed tool demonstrates the utilisation of BIM technology to promote pro-active carbon mitigation and safety performance strategies.

A financial decision making framework for construction projects based on 5D Building Information Modeling (BIM)

“…Contractors can optimize the schedule by integrating quantities of materials provided by the BIM model with the productivity rate of construction crews and predict the accurate project cost at different project time (Kala et al, 2010;Sattineni and Macdonald, 2014;Smith, 2014;Vicosoftware, 2007). Apart from cost and schedule estimation, 5D BIM can also facilitate specific aspects (Kim et al, 2014;Wong et al, 2014). For example, Wong et al (2014) utilized 5D BIM technology to promote pro-active carbon mitigation and improve on-site safety.…”

What do post-disaster reconstruction project success indicators look like? End-user’s perspectives

“…Tay et al (2017) informed of the safety and quality trends and applications of three-dimensional printing towards construction precision and sustainable buildings. These technologies are applicable in many areas of improvement, including, post-disaster reconstruction (Moles et al, 2014), worksite and building use optimisation (Small and Baqer, 2016;Chardon et al, 2016), decrease environmental issues, including carbon foot-print (Foroozanfar et al, 2017;Wong et al, 2014) and project constructability (Kifokeris and Xenidis, 2017). These emerging technologies compel the industry practitioners to embark on a personal development path towards improving competence.…”

A Vision of the Future Construction Industry of Hong Kong

“…With such system working on-site, the relative locations between workers and the danger zones can be detected real-time and thus generating warning signals to avoid accidents [19]. Other BIM-related studies, such as BIM-based system for estimation and planning of demolition and renovation construction waste linking to the Hong Kong government's waste charging scheme, distributed cloudbased social BIM framework which could support collaboration among project participants and information sharing, cloud computing integration with BIM technology in the construction, integrated 5D BIM for quantification of construction process emissions and accident identification, virtual prototyping framework for simulating construction process and so on, have also been developed or being studied in the local construction industry [20][21][22][23][24].…”
