Building necessitates multi-disciplinary teams that typically do not collaborate until construction (VDC) begins and duties are assigned to another project.
VDC moves planning and decision-making to the start of the building process when it’s easier to decrease risk, analyze performance, and avoid cost and schedule overruns.
In its most basic form, virtual design and construction create the project digitally, ironing out the major issues and then constructing it more effectively in the physical world.

Why is virtual design and construction (VDC) used in construction?
In recent decades, construction methods have remained unchanged—paper documentation is still widely used. And spreadsheets are still used in far too many operations. According to the JB Knowledge ConTech Survey for 2021, spreadsheets are used in 45 per cent of project management workflows.
The spreadsheet is only as good as its programming, and mistakes may go undetected until they cause a problem. It’s challenging to restrict users’ rights while allowing them access to their required information. And if incorrect data is entered into a spreadsheet, it might be challenging to figure out when it was entered, who entered it, and why.
Overview of virtual design and construction
Researchers at Stanford University’s Center for Integrated Facility Engineering (CIFE) developed VDC in 2001. CIFE has been working to improve how the AEC industry organizes, conceptualizes, and executes design and construction since the late 1980s.
Projects are essentially built twice. Instead of wasting time, it helps you save it. “Measure twice, cut once” is an aphorism we’ve all heard. VDC applies this approach to the entire construction process rather than carpenter labour.
A framework for virtual data centres
The Building Construction companies in West London provide the most basic and understandable framework for understanding this process.
Construction teams generate virtualized construction models and timeframes to transform concepts, expectations, and performance goals into the most effective plan feasible.The following VDC models are available:
Concentrate on the asset, the teams who will define, design, build, and run it, and the process they will use.
They are integrated to share data, and dependencies to relevant models can be captured when a user makes a change.
Can forecast aspects of project performance and show how they connect to the project’s goals.
They are adaptable and interactive, ensuring that all project stakeholders access the required information.
Construction teams use product and process modelling software, organizational visualization software, and online communication tools to generate these models. Project teams can use these technologies to create photo-realistic representations of built spaces to increase stakeholder communication.
To perform collision detection and examine constructability, design teams can mix models of multiple building components, such as structural, architectural elements, and fire suppression systems.
- VDC words that are commonly used
- You may come across a lot of frequent terms while you research VDC:
- Modelling of Building Information (BIM)
The terms BIM and VDC are frequently used interchangeably, which is erroneous (more on that later). The technique of creating 3D models is known as BIM. Many VDC teams use BIM software to produce 3D models of the built asset.
The Data Environment as a Whole (CDE)
A shared data environment serves as the single source of truth for all project data. Models, contracts, reports, and estimations, among other things, are all stored in cloud-based software that users may access from any location. A CDE is critical for reducing data silos.
Design helped by computers (CAD)
The use of software to develop, edit, or analyze designs is known as computer-aided design. Since its inception in the late 1950s, computer-aided design (CAD) has reduced the need for manual drafting. It can be used to make two-dimensional or three-dimensional models. While VDC methods may or may not include BIM, CAD is essential for creating VDC models.
Foundation Classes in the Industry (IFC)
Industry foundation classes are CAD data exchange file formats that improve interoperability across various construction systems. IFC is an open standard developed by buildingSMART that supports vendor-agnostic capabilities across several construction technologies.
Virtual design and construction advantages
VDC provides wide-ranging benefits throughout the construction lifecycle by front-loading crucial decisions at the start of the project.
End-User And Worker Safety Has Improved
Designers are frequently entrusted with taking worker and end-user safety into account during the design process. However, preventing accidents is difficult when potential threats are unknown. VDC models’ realism and depth of information enable design teams to foresee dangers more correctly. Contractors can provide feedback on safety issues and use the information provided by the model to train and prepare their teams for hazards that cannot be avoided during the design phase, as VDC models are designed to be used by multi-disciplinary teams.
Collaboration with Non-Technical Experts
Many stakeholders require an understanding of design and construction intent but lack the knowledge to comprehend technical drawings and documents. With easy-to-understand visuals and animations, VDC allows government leaders, CEOs without specialized experience, and members of the general public to get an idea of what a project includes.
Risk Reduction
In the construction industry, risk mitigation is a never-ending uphill battle. Prior knowledge and risk management expertise frequently identify project hazards such as miscalculations, disagreements, and financial blunders. VDC enables construction teams to precisely predict each project’s possible hazards, reducing surprises and keeping schedules and timetables on track.
Planning for the Future
VDC can help project teams examine energy efficiency, carbon emissions, environmental implications, and more as the construction industry confronts sustainability. For instance, addressing embodied carbon—the greenhouse gases emitted during construction—is becoming increasingly important.
VDC can be used to examine multiple energy scenarios and plan for grid flexibility as renewable energy sources and onsite energy storage become increasingly common. Innovative materials can help minimize embodied carbon, but it’s also vital to consider how they affect the cost, labour, and equipment requirements, which can be done more precisely with VDC.
Construction teams can use simulations to see how adding or removing walls affects ventilation and occupant comfort for Construction companies in West London, decide whether to include space for future wiring or cabling and plan for future electric vehicle charging expansion.
