Virtual Construction
Virtual Design and Construction (VDC) is an innovative concept in the construction industry that leverages digital technologies to coordinate and intelligently execute the design, planning, construction, and operation of projects. VDC goes beyond Building Information Modeling (BIM) and aims to integrate design, engineering, construction, and operation processes in a data-driven virtual environment.
🔹 Definition of VDC (Virtual Design and Construction)
In simple terms, VDC means:
Designing, planning, and managing the construction process in a digital environment before actual project execution.
This concept includes:
Building Information Modeling (BIM)
Construction planning (4D, 5D, and beyond)
Stakeholder coordination (owner, designer, contractor)
Simulation of technical, time, and financial performance before execution
🔹 Key Components of Virtual Design and Construction (VDC)
BIM (Building Information Modeling):
Creating an intelligent digital model of the project (architecture, structure, MEP)
The fundamental basis of VDC for information integration.
PPM (Project Production Management):
Managing project planning and control through data-driven approaches
ICE (Integrated Concurrent Engineering):
Simultaneous collaboration of teams in a shared digital environment for fast decision-making
Simulation:
Simulating execution processes, energy consumption, cost, time, etc. for pre-construction analysis
🔹 Benefits of Using VDC
| Benefit | Description |
|---|---|
| Error and rework reduction | Errors are identified before construction through simulations |
| Improved team coordination | All stakeholders collaborate on a unified digital model |
| Reduced project cost and time | More accurate decision-making and optimized planning |
| Higher construction quality | Through precise and consistent data |
| Performance analysis | Including energy, carbon, cost, maintenance, and safety |
🔹 Difference Between VDC and BIM
| Feature | BIM | VDC |
|---|---|---|
| Focus | 3D building information model | Management of the entire project lifecycle |
| Tools | Modeling software (Revit, Navisworks, etc.) | Combination of BIM + planning + concurrent collaboration |
| Goal | Creating a digital model | Decision-making, optimization, and successful execution |
🔹 Applications of VDC in Advanced Projects
Large-scale infrastructure projects (metro, highways, power plants)
Hospitals and airports
Government-funded or high-coordination construction projects
Green projects aimed at reducing energy consumption and carbon footprint
🔹 Conclusion
Virtual Design and Construction (VDC) is a digital transformation in the construction industry that integrates technology, data, and multidisciplinary collaboration to reduce risks, enhance efficiency, and enable the successful delivery of complex projects. In developed countries, it is recognized as the golden standard of construction management, and in Iran, it is entering large-scale infrastructure and government projects.
Questions?
Yes, the implementation of VDC in Iran is absolutely feasible, especially in large-scale governmental and infrastructure projects. The software infrastructure (such as Revit, Navisworks, Synchro, etc.) and the pool of skilled professionals in the country are steadily growing. Moreover, with organizations like the Plan and Budget Organization and institutions such as Tehran Municipality moving toward Building Information Modeling (BIM), the legal and operational framework for adopting VDC is also being established.
Currently, companies such as BayaBIM are actively developing VDC services in hospital, metro, and building projects, demonstrating that the localization of this technology is both achievable and beneficial.
Virtual Design and Construction (VDC) transforms project management. The main advantages are:
-
Cost Reduction: Through precise simulation and prevention of rework
-
Shorter Construction Time: By optimizing planning and coordination among teams
-
Improved Quality and Safety: By identifying risks and resolving conflicts before execution
-
Better Decision-Making: Using real data and project performance simulations
-
Energy, Carbon, and Cost Control: To achieve sustainability and economic goals
Globally, VDC has become the gold standard in advanced project management. Countries such as:
🇺🇸 USA: Companies like DPR Construction and Stanford CIFE are pioneers in VDC development.
🇸🇪 Sweden and Finland: Governments have mandated BIM/VDC implementation in public projects.
🇸🇬 Singapore: With the establishment of BCA and BIM legal requirements, digital construction has reached maturity.
Reports indicate that implementing VDC can:
Save up to 25% in costs
and up to 30% in project execution time.
Developing countries are also rapidly entering this space, and Iran, given its current infrastructure, has the potential for regional competitiveness.
🧩 Steps to Implement VDC in a Company:
1. Kick-off / Needs Assessment Meeting:
Attendees: Project Manager, Technical Team (BIM), Client, and Consultant
Objective: Define goals, constraints, expectations, and digital project requirements
2. Preparation of EIR (Employer’s Information Requirements):
This document serves as the client’s roadmap and defines:
What information is required?
At what Level of Detail (LOD)?
At which stages/times?
In which formats?
This document will form the basis for the entire BIM and VDC program.
3. Development of BIM/VDC Strategy:
Prepared by the consultant or BIM team
Includes:
Digital team structure (BIM Manager, Coordinator)
Tools and software to be used (Revit, Navisworks, Synchro, Power BI)
Information exchange framework (ISO 19650 or local standards)
4. Team Training and Empowerment:
Intensive courses for engineers and project managers
Training on software and collaborative processes (ICE, CDE, etc.)
5. Gradual Implementation of VDC in a Pilot Project:
Controlled execution in a single phase of a real project
Evaluation of results and issue resolution
💰 Estimated Cost of Implementing VDC in Companies
Costs depend on project size, contract type, and level of implementation. Approximate items include:
| Item | Estimated Cost (IRR) |
|---|---|
| Kick-off meeting and EIR preparation | According to professional association rates |
| BIM/VDC strategy design | According to professional association rates |
| Pilot implementation in a project | According to professional association rates |
| Continuous training and consulting | According to professional association rates |
✅ Note: Implementing VDC in a large project typically results in 10–20% savings in total construction costs, making these investments quickly recoverable.
