Virtual models work as a platform for embedding and visualizing the lifecycle information of the projects. Virtual models are capable of storing information that can be used over the lifecycle of a facility are called building information models. These models can be produced and navigated using software such as Autodesk Revit, Bentley architecture, and Navisworks. These models contain a virtual representation of physical components and can serve as a platform for visualizing and monitoring the construction activities’ status. In the integration of CPSs, acquired information from wireless sensors is visualized in virtual models and occasionally stored in identical virtual components. Project stakeholders can inquire about the virtual components to access embedded information or to embed information. For example, designers can embed data and information (relating to design reviews or updates) into the virtual components, such that these are transmitted to the tags on the physical components and accessed on the construction job site and vice versa. The virtual models can also be a platform for remotely controlling the components of the physical world.
Modeling construction equipment in 4D simulation
Published in Jan Karlshøj, Raimar Scherer, eWork and eBusiness in Architecture, Engineering and Construction, 2018
Navisworks Manage (Autodesk, 2018) is 4D BIM software widely utilized in the construction industry. It supports the animation of path planning (relocation), equipment/workspace collision avoidance, and conflict reports. This tool can be used to identify, inspect, and report the following construction clashes in a 3D model: (1) clashes between a couple of equipment, (2) conflicts between equipment and workspaces. Figure 5 shows two pieces of equipment moving toward each other. Their movements caused conflicts between both equipment/equipment and workspace/equipment. The 3D model of a boom lift is downloaded from a website (Graydon, 2016) in STP format, before importing it into Synchro software to add workspaces. After both the equipment and the workspaces around them are prepared, the model is saved in FBX format and imported into Navisworks software. After creating the animation, a hard clash test is applied between two boom lifts and their workspaces.
From LiDAR data towards HBIM for energy analysis

Most of the processes carried out to generate HBIM consist of mapping architectural elements onto laser scan or photogrammetric survey data using BIM software such as Autodesk Revit and Navisworks, Bentley Architecture, Graphisoft ArchiCAD or Tekla (Fai et al., 2011; Brumana et al., 2013; Oreni et al., 2014). Point clouds and images are used as templates, and consequently, HBIMs are manually modelled by placing, positioning and extruding architectural elements. There is the need to streamline EBIM/HBIM reconstruction by using semi-automated and automated techniques (Tang et al., 2010). Intense efforts have been made in recent years to automate the EBIM reconstruction. Specialized software in the area of reverse engineering incorporates developed tools to allow the rapid generation of BIM components from point clouds. Nonetheless, these solutions are far away from automated or semi-automated (Volk, Stengel and Schultmann, 2014).
A BIM-based approach to automate the design and coordination process of mechanical, electrical, and plumbing systems
Published in HKIE Transactions, 2018
Building Information Modelling (BIM) is the digital representation of physical and functional characteristics of a facility [3]. With the advent of BIM technologies, the conventional MEP coordination process has been changed and improved with various potential coordination issues addressed. 3D BIM models enable engineers to visualise the size, location and routings of different building systems. BIM also allows smooth integration of MEP systems to the architectural and structural envelope. The spatial interferences can be quickly identified in the 3D environment, which cannot be easily identified for traditional 2D based coordination, reducing actual reworks onsite. In addition, some BIM software platforms like Autodesk Navisworks provide a comprehensive solution to conduct automated clash detection.
