Virtual design and construction (VDC) is changing the construction industry. By integrating virtual modeling, design, and construction techniques, stakeholders can coordinate, visualize, and simulate construction projects before physical work begins. This, in turn, can enhance collaboration, minimize errors, and maximize project efficiency.
Hexagon’s Building Solutions, a leading provider of reality capture analysis solutions, offers a platform that automates the comparison of digital design models with on-site construction progress. This article will delve into VDC. We’ll start by outlining what VDC is and what VDC techniques are in construction. We’ll then touch on some strategies and tools construction managers can use to implement VDC. Lastly, we’ll cover how Building Solutions fits into the VDC process and how our capabilities can help make the construction process more efficient.
What Is Virtual Design and Construction?
Virtual design and construction (VDC) is a process that utilizes digital tools and technologies — including Building Information Modeling (BIM) — to enhance collaboration, communication, and coordination throughout the entire construction lifecycle.
Essentially, VDC integrates 3D modeling, data analytics, and project management techniques to optimize the lifecycle of a project, from pre-construction and project planning all the way through construction and facility management.
VDC starts during the preconstruction phase, where design teams create a 3D model of the project using BIM software. This allows for early clash detection, identification of design conflicts, and optimization of construction sequencing and logistics. In addition to using the 3D models in preconstruction, site logistics and work sequencing takes place leveraging reality capture technologies such as laser scanning and drones. This allows for the building information model to contain the most current as-built information about the site or location for planning purposes. The BIM is much more than just the 3D model.
During the construction phase, VDC techniques help improve project efficiency and reduce errors. 4D modeling adds the dimension of time to the BIM model, allowing stakeholders to visualize construction sequences and identify potential conflicts. Clash detection tools analyze the BIM model to detect clashes between different building elements, such as mechanical, electrical, and structural systems. This enables early problem resolution, reducing costly rework and delays. Building Solutions take this a step further in construction and run clash detection between the 3D BIM model and the as-built conditions as captured in laser scans, effectively clashing the model to the real world.
VDC also extends beyond construction completion. The virtual model created during the design and construction phases can be leveraged for facility management and maintenance. Since Building Solutions creates an updated as-built model of changes to the coordinated model along the course of construction, your deliverables upon project completion will be accurate and ready for operations. By incorporating data on building systems, equipment, and materials into the model, facility managers can use the digital twin produced as a valuable tool for asset management, space planning, and maintenance scheduling.
What VDC Techniques Apply to the Construction Industry?
The use of virtual design and construction has grown tremendously on construction sites. Below are a few of the most common VDC techniques currently being used by project teams:
- Building Information Modeling (BIM):Â BIM is a central component of VDC, enabling the creation of a digital model/representation of a building or infrastructure project. It includes geometric information, spatial relationships, quantities, and properties of various building components.
- Clash detection and coordination: VDC tools allow for clash detection, which identifies potential conflicts between different building systems or elements early in the design process, reducing rework and improving coordination. VDC’s clash detection tools can be particularly useful for mechanical, engineering, and plumbing (MEP) subcontractors.
- 4D and 5D modeling:Â VDC incorporates time (4D) and cost (5D) dimensions into the BIM model, enabling construction professionals to visualize the project’s schedule, simulate construction sequencing, and estimate costs accurately.
- Prefabrication and modular construction:Â VDC facilitates off-site construction by leveraging digital design models to precisely plan and prefabricate building components. This technique improves construction efficiency, reduces waste, and enhances quality control.
What Are the Best Tools to Maximize VDC?
The benefits of VDC are endless, especially if paired with other construction technologies. Below are some of the best tools that you can consider implementing into your building project to help get the most out of your VDC efforts.
- Collaboration platforms:Â Cloud-based platforms enable real-time collaboration, document management, and issue tracking among project stakeholders.
- Laser scanning & 360 Reality Capture:Â Laser scanning technology captures as-built conditions on-site and creates highly accurate point cloud data, which can be integrated with BIM models for clash detection and quality assurance. 360 photography and videos can track progress and provide access to a virtual version of the project, enabling more collaboration and enhancing safety through unnecessary or redundant site visits.
- Virtual reality (VR) and augmented reality (AR): VR and AR technologies offer immersive experiences that allow stakeholders to visualize building designs, identify potential issues, and make informed decisions during the design and construction phases. Virtual reality allows stakeholders to see a virtual model, while augmented reality adds to the virtual model. As PC Mag describes, “virtual reality replaces your vision, augmented reality adds to it.”
- Cloud computing:Â Cloud-based platforms like Microsoft Azure and Amazon Web Services provide scalable storage, computational power, and data-sharing capabilities for large-scale VDC projects.
- Automation and machine learning: AI-driven tools automate repetitive tasks, optimize workflows, and extract valuable insights from construction data, enhancing productivity and decision-making.
- Robotics:Â Robots exist now for laying out the linework from the 3D model directly onto the floor to build from within one-sixteenth of an inch. Drones capture autonomously from the sky and from the floor level and feed data into the real-time BIM models. These can be used in future analysis. In select instances, robots can be programmed to drill, weld, or install certain pieces of work as dictated by the BIM models.
