VDC in infrastructure projects

Virtual design and construction (VDC) is increasingly being used in infrastructure projects to improve efficiency, reduce costs, and minimize risks. Here are some of the ways in which VDC is typically undertaken for infrastructure projects:

1. Building Information Modeling (BIM): BIM is a 3D modeling software that enables design and construction teams to collaborate and share project data in a centralized location. BIM allows designers to create a virtual prototype of the project, which can be used to identify and address design conflicts before construction begins.

2. Virtual Reality (VR): VR technology can be used to create immersive experiences that allow designers and stakeholders to visualize and interact with the project in a virtual environment. VR can be particularly useful for reviewing and refining design details, such as lighting, materials, and finishes.

3. Augmented Reality (AR): AR technology can be used to overlay virtual design elements onto the real-world construction site, allowing contractors to visualize how the project will look once completed. AR can also be used for quality control and safety inspections.

4. Laser Scanning: Laser scanning can be used to capture precise measurements of the existing site conditions, which can then be used to create accurate 3D models. Laser scanning can save time and reduce errors during the design and construction phases.

According to a study by Dodge Data & Analytics, projects that use VDC technologies see an average cost savings of 5.5% during construction and 8.9% during the operation of the facility. Additionally, VDC projects are completed on schedule 48% more often than traditional projects.

data related to infrastructure projects and the use of virtual design and construction (VDC) technologies:

1. The Massachusetts Bay Transportation Authority (MBTA) used laser scanning and BIM technologies to complete a complex track reconstruction project on the Red Line subway system. The use of VDC technologies helped reduce the project timeline by 50% and resulted in $1.2 million in cost savings.

2. The California High-Speed Rail Authority (CHSRA) used BIM to design a 65-mile section of high-speed rail track, which included 1,200 structures and 32 bridges. The use of BIM helped reduce design errors and improved collaboration between designers, contractors, and stakeholders.

3. The Ohio Department of Transportation (ODOT) used laser scanning and BIM technologies to complete a bridge rehabilitation project on the I-90 Innerbelt Bridge. The use of VDC technologies helped reduce the project timeline by 25% and resulted in $4.4 million in cost savings.

4. The Port of Long Beach in California used laser scanning and BIM technologies to design a new intermodal rail yard. The use of VDC technologies helped reduce design errors and improved collaboration between the various project stakeholders.
