Virtual Design and Construction (VDC) is a process that utilises advanced technology to create digital representations of construction projects.
In the construction phase, VDC helps to increase efficiency and decrease risks because it facilitates better visualisation, collaboration, and coordination among project teams. VDC helps streamline project management by integrating various aspects such as 3D modelling, clash detection, scheduling, cost estimation, and more.
So, what is VDC, and how is it different from BIM? Continue reading to learn more about this topic.
Virtual design and construction is a process that combines digital models with traditional project planning and management techniques. Architects, engineers, and contractors use VDC models to visualise and plan building designs, processes, schedules, and budgets.
According to the Trimble Construction blog, VDC was developed in 2001 by researchers at Stanford University’s Center for Integrated Facility Engineering (CIFE). VDC uses new technologies such as drones, laser scanners, 3D modelling, and cameras to create a complete picture of a construction project during the pre-construction phase.
Before we get deeper into the VDC topics, you may need to learn about other aspects of construction project management, one of which is the model coordination process. To learn more, check out our article, “Model Coordination in BIM: What It Is and the Main Components“.
Benefits of Virtual Design and Construction
Virtual design and construction is a holistic approach to building design, construction, and management that uses advanced technology to improve the construction process. VDC has many benefits, including:
- Improved communication and collaboration: VDC can help reduce rework by ensuring that everyone is on the same page at every stage.
- Improved project estimates: VDC can help construction companies understand the quantity and cost of completing a project. It can also help improve preconstruction cost analysis and detailing for more accurate bids and estimates.
- Enhanced construction safety: VDC can help protect the safety of workers by identifying potential hazards before construction begins.
- Improved quality: VDC can help improve quality and visualization.
- Cost savings: VDC can help save time and money by offering a high degree of planning reliability, high printing speed, and low coordination effort.
What is the difference between BIM and VDC?
Building Image Modelling (BIM) technology and Virtual Design and Construction are fundamentally related. The only difference between the two is their intended purpose. According to Autodesk’s website, BIM technology generates a digital representation of a physical structure. VDC technology employs 3D BIM models and other data to digitally plan every aspect of a construction project, from cost estimation to scheduling and risk management.
Here is the key difference between those two:
- Focus: BIM focuses on creating a comprehensive digital representation of the building, while VDC focuses on using digital models to plan and optimize the construction process.
- Application: BIM is used throughout the entire life cycle of a project, while VDC is primarily used during the construction phase.
- Scope: BIM encompasses design, visualisation, simulation, and analysis, while VDC is more focused on construction planning, sequencing, and coordination.
Ultimately, building information modelling (BIM) and value-driven construction (VDC) are not interchangeable but rather serve different purposes in the building sector.

Implementation Challenges and Best Practices
Virtual Design and Construction implementation can provide numerous benefits to construction projects, but they also presentunique challenges. Technology adoption, data integration, interoperability, skill gaps, and initial costs are some of the challenges that must be addressed when implementing VDC.
With best practices in place, AEC firms can implement VDC and maximise its potential to improve project outcomes, increase efficiency, and reduce costs. Collaboration among project stakeholders, clear communication, and ongoing training are some of the best practices for VDC implementation.
While the challenges and best practices for VDC implementation vary by project, here are some key considerations that can help ensure successful VDC implementation in the AEC industry.
VDC Implementation Challenges
- Technology Adoption: Integrating new technologies and software tools into existing workflows can be challenging, requiring training and change management efforts.
- Data Integration: Ensuring seamless integration of data from various sources, disciplines, and project phases can be complex and may require standardised protocols and collaboration among stakeholders.
- Interoperability: Compatibility issues between different software and file formats used by various project stakeholders can hinder the smooth exchange of VDC data.
- Skill and Knowledge Gap: VDC requires specialised skills and knowledge, and organisations may face challenges in finding and retaining talent with expertise in this area.
- Cost: Implementing VDC technologies and processes may require substantial initial investment, which can be a barrier for some organisations.
VDC Implementation Best Practices
- Leadership and Commitment: Strong leadership support and commitment to VDC implementation from top management are crucial for overcoming challenges and driving successful adoption.
- Collaboration and Communication: Emphasise open communication and collaboration among project stakeholders to ensure a shared understanding of VDC processes and objectives.
- Training and Education: Provide comprehensive training and educational programs to upskill existing staff and ensure they are proficient in VDC technologies and methodologies.
- Standardisation: Establish standardised protocols and guidelines for data exchange, software usage, and VDC processes to improve interoperability and data integration.
- Pilot Projects: Implement VDC in smaller pilot projects to assess its effectiveness, identify challenges, and refine processes before scaling it to larger projects.
- Continuous Improvement: Encourage a culture of continuous improvement, where feedback from VDC implementation is used to refine processes and enhance future projects.
- Risk Management: Identify and address potential risks associated with VDC implementation, such as cybersecurity concerns and data privacy issues, to mitigate their impact.
VDC is only one part of the construction project management process. Another important aspect is to include the as-built documentation. Our article, “As-Built Documentation: What It Is, Components, and Methods“, will help you learn more about the concept and components from as-built documentation.
Conclusion
When it comes to building projects, virtual design and construction are game-changers. It can help save money, increase efficiency, ensure a successful outcome, and make the industry more sustainable in the long run. By embracing VDC, construction firms can improve project outcomes and stay ahead of technological advancements, giving them a competitive edge in a dynamic business environment.
