VR Design Reviews:
The Complete Guide to Eliminating Costly Engineering Errors Before Construction
Engineering projects have become increasingly complex. Modern industrial facilities involve thousands of interconnected components, multiple engineering disciplines, strict safety requirements, and aggressive project schedules. Yet many organizations still rely on 2D drawings, PDF markups, and screen-based model reviews to validate designs before construction begins.
The result is familiar. Design conflicts are discovered on-site instead of during engineering. Equipment becomes difficult to maintain. Pipe routes interfere with structural elements. Operators cannot safely access critical valves. Engineering Change Orders (ECOs), Requests for Information (RFIs), schedule delays, and expensive rework quickly follow.
VR design reviews provide a fundamentally different approach. Instead of interpreting drawings on a monitor, engineers can walk through a full-scale digital representation of the facility before a single piece of steel is fabricated or installed. Mechanical, electrical, civil, structural, process, operations, maintenance, BIM, and safety teams can review the same model together, identify issues early, and make informed decisions with greater confidence.
Research continues to demonstrate the value of immersive engineering. According to the National Institute of Standards and Technology (NIST), inadequate interoperability in the capital facilities industry contributes to billions of dollars in avoidable costs annually. Likewise, studies from Stanford University’s Center for Integrated Facility Engineering (CIFE) have shown that improving design coordination before construction significantly reduces costly field changes and improves project delivery outcomes.
For Engineering, Procurement, and Construction (EPC) firms, owner-operators, manufacturers, and industrial engineering teams, Virtual Reality (VR) Design Reviews have evolved from an innovation initiative into a practical engineering workflow that improves quality, reduces project risk, and accelerates decision-making.
This guide explains how VR design reviews work, why they matter, the engineering problems they solve, and how organizations can successfully integrate immersive design validation into modern engineering workflows.
What are VR Design Reviews?
VR design reviews are collaborative engineering sessions where teams review Building Information Modeling (BIM), Computer-Aided Design (CAD), or Digital Mock-Up (DMU) models inside an immersive Virtual Reality environment before construction or manufacturing begins.
Unlike traditional design reviews, VR enables stakeholders to experience the project at a true 1:1 scale. Engineers can move naturally through facilities, inspect equipment from multiple perspectives, evaluate spatial relationships, and validate constructability, operability, accessibility, and safety in ways that are difficult to achieve using conventional desktop applications.
Rather than replacing existing engineering software, VR Design Reviews extend the value of existing digital assets. Models created in applications such as Autodesk Revit, Navisworks, AVEVA E3D, Bentley OpenPlant, Hexagon Smart 3D, Siemens NX, CATIA, or SolidWorks can be brought into an immersive environment where multidisciplinary teams collaborate around a shared source of truth.
The objective is simple: identify engineering issues when they are still inexpensive to resolve.
Instead of discovering problems during construction or commissioning, project teams can resolve them during design, when modifications require only digital updates rather than field rework.
Why are VR Design Reviews becoming essential?
Several industry trends are driving wider adoption.
Industrial facilities are becoming more complex.
Projects involve larger multidisciplinary teams distributed across multiple offices and countries.
Owner expectations continue to increase while project schedules continue to shrink.
At the same time, the cost of late-stage engineering changes continues to rise.
Traditional review methods struggle to provide the spatial understanding required to evaluate these increasingly sophisticated projects. A piping layout that appears acceptable on a monitor may reveal severe maintenance access issues when experienced at full scale.
Virtual Reality bridges that gap between digital models and real-world understanding.
Why do traditional engineering design reviews miss costly errors?
Traditional design review processes have served engineering teams for decades. However, they were developed when projects were less complex and digital collaboration was far more limited.
Today’s industrial projects demand a higher level of visualization and multidisciplinary coordination than conventional review methods can consistently provide.
Several limitations contribute to late-stage engineering errors.
Limited spatial understanding
Even experienced engineers often need to mentally convert 2D drawings or monitor-based 3D models into real-world spaces.
This process becomes increasingly difficult as facilities grow in complexity.
Questions such as these are difficult to answer from a desktop view alone:
- Can maintenance personnel safely remove this pump?
- Is there enough clearance around the heat exchanger?
- Can operators reach emergency shutoff valves?
- Will overhead piping interfere with lifting operations?
- Can two technicians work simultaneously in this confined space?
Virtual Reality allows reviewers to experience these situations naturally rather than imagining them.
Design reviews often occur in silos
Mechanical engineers review mechanical systems.
Electrical teams review electrical layouts.
Civil engineers validate structural components.
Operations teams may not participate until much later.
Each discipline performs valuable reviews, but critical issues often emerge where disciplines intersect.
VR Design Reviews encourage cross-functional collaboration by bringing every stakeholder into the same immersive environment at the same time.
This shared understanding significantly improves communication and speeds up decision-making.
Desktop reviews cannot replicate human experience
A facility may satisfy every engineering standard and still be difficult to operate safely.
Examples include:
- Valves positioned behind structural members
- Instruments hidden from operators
- Restricted escape routes
- Poor maintenance access
- Limited visibility around critical equipment
- Unsafe ladder placement
These issues become immediately obvious when experienced from a first-person perspective inside Virtual Reality.
Late issue discovery increases project costs
Every engineering organization understands the financial impact of finding problems after construction begins.
Late design changes may trigger:
- Engineering Change Orders (ECOs)
- Requests for Information (RFIs)
- Construction delays
- Additional procurement
- Material waste
- Schedule overruns
- Reduced productivity
- Increased project risk
The earlier issues are identified, the lower the cost of resolving them.
That principle makes early immersive design validation one of the highest-value applications of Industrial Extended Reality (XR).
How do VRVR design reviews work?
A successful VR design review is not simply a model walkthrough. It is a structured engineering process that integrates with existing CAD, BIM, and project management workflows. Although implementation varies between organizations, most industrial projects follow a similar sequence.

BIM To VR
Step 1. Aggregate engineering models
Engineering teams first combine models from multiple disciplines into a coordinated project environment.
These typically include:
- Structural models
- Mechanical systems
- Electrical layouts
- Process equipment
- Piping
- Instrumentation
- HVAC systems
- Architectural components
Maintaining a coordinated model ensures every stakeholder reviews the latest approved design information.
Step 2. Prepare the model for immersive review
Engineering models often contain millions of polygons and detailed metadata.
The project is optimized for virtual reality while preserving engineering accuracy, allowing reviewers to navigate complex industrial facilities smoothly without compromising critical design information.
Step 3. Conduct collaborative VR Design Reviews
Project stakeholders enter the virtual environment together.
Participants may include:
- Design engineers
- Project managers
- Operations personnel
- Maintenance teams
- Safety specialists
- Construction managers
- Owner representatives
Instead of reviewing screenshots, they evaluate the design as though they are physically inside the completed facility.
This immersive perspective improves communication because everyone observes the same conditions simultaneously.
Step 4. Capture engineering issues
As reviewers identify concerns, issues are documented, categorized, and assigned to the appropriate engineering discipline.
Examples include:
- Spatial conflicts
- Maintenance access limitations
- Safety observations
- Equipment clearance concerns
- Human factors
- Constructability challenges
- Operational improvements
The review becomes a structured engineering validation exercise rather than an informal discussion.
Step 5. Update the engineering model
Engineering teams resolve identified issues within their native CAD or BIM applications.
The updated model can then be reviewed again until stakeholders are confident that major engineering risks have been addressed before procurement or construction begins.
This iterative workflow creates a continuous feedback loop that improves design quality while reducing downstream project uncertainty.
What engineering errors can VR design reviews identify before construction?
The primary objective of a VR Design Review platform is to identify engineering issues while they still exist in the digital environment. At this stage, changes can be made quickly, reviewed collaboratively, and implemented before fabrication or construction begins.
Unlike traditional design reviews, virtual reality provides true spatial awareness. Teams are no longer interpreting drawings or rotating models on a monitor. They are evaluating the design from the perspective of the people who will build, operate, inspect, and maintain the facility.
This immersive approach helps uncover problems that are often difficult to identify using conventional review methods.
Spatial clashes and design coordination issues
Clash detection software has become a standard part of Building Information Modeling (BIM) workflows. However, not every conflict is automatically detected.
Many engineering challenges involve “soft clashes” where there is technically no collision, but the available space is insufficient for construction, maintenance, or safe operation.
For example:
- Pipework routed too close to electrical cable trays
- Structural steel limiting access to process equipment
- HVAC ducts reducing maintenance clearance
- Instrument panels obstructing operator movement
- Platforms interfering with equipment installation
Viewing these conditions at full scale enables engineering teams to assess whether the design works in practice, not just in theory.
Maintenance accessibility
A design may meet engineering specifications while still creating long-term maintenance challenges.
Maintenance engineers often discover that equipment cannot be removed without dismantling surrounding systems or creating unnecessary downtime.
VR design reviews allow maintenance teams to validate:
- Pump removal paths
- Motor replacement clearances
- Heat exchanger access
- Valve maintenance space
- Instrument servicing locations
- Filter replacement areas
- Crane and lifting paths
Including maintenance personnel early in the review process helps improve lifecycle performance while reducing future operational costs.
Operator visibility and ergonomics
Industrial facilities should be designed for the people who use them every day.
Operators need clear visibility of instruments, alarms, control panels, and surrounding equipment. They also need safe and comfortable access to routine operating tasks.
Inside a virtual reality training environment, operators can evaluate whether they can:
- Read gauges without obstruction
- Access emergency shutdown systems
- Reach manual valves comfortably
- Navigate safely through process areas
- Perform inspections without unnecessary hazards
Human-centered design becomes significantly easier when users can experience the facility before construction.
Constructability challenges
Some designs appear practical on paper but become difficult to construct in the field.
Construction teams can use VR to review:
- Equipment installation sequences
- Crane positioning
- Module transportation routes
- Scaffold requirements
- Material handling constraints
- Temporary access requirements
Identifying constructability issues during design reduces installation delays and minimizes costly field modifications.
Safety and compliance concerns
Safety reviews benefit significantly from immersive visualization.
Engineering teams can evaluate scenarios that are difficult to communicate using drawings alone.
Examples include:
- Emergency evacuation routes
- Confined space accessibility
- Fire equipment placement
- Lockout/Tagout (LOTO) access
- Fall protection requirements
- Safe working clearances
- Visibility around hazardous equipment
According to the Occupational Safety and Health Administration (OSHA), designing safer workplaces before construction is one of the most effective methods for reducing operational risk.
Virtual Reality supports this proactive approach by allowing stakeholders to validate safety during design rather than after installation.
Operational efficiency
Operations teams often identify improvements that designers may overlook.
Questions frequently raised during VR Design Reviews include:
- Is there enough space for two technicians to work simultaneously?
- Can forklifts safely navigate the layout?
- Are operator routes efficient?
- Will equipment interfere with production workflows?
- Is future expansion possible?
These discussions improve long-term operational efficiency while reducing costly redesigns after commissioning.
Why VR Design Reviews deliver value across the entire project lifecycle
Many organizations initially adopt Virtual Reality for design visualization. They soon discover that its value extends well beyond early engineering reviews.
From concept development to facility operations, immersive design validation supports better decisions throughout the project lifecycle.
Concept design
During conceptual engineering, teams evaluate multiple layout options before detailed design begins.
VR allows project stakeholders to understand space requirements, equipment arrangements, and workflow implications far more effectively than reviewing conceptual drawings.
This leads to faster alignment between engineering teams, project owners, and decision-makers.
Front-End Engineering Design (FEED)
Front-End Engineering Design (FEED) establishes the technical foundation for the project.
Errors introduced during this stage often become expensive to correct later.
VR Design Reviews help engineering teams validate:
- Overall plant layout
- Equipment positioning
- Process flow
- Access requirements
- Initial safety cdesign reviewsonsiderations
- Construction feasibility
Resolving these issues during FEED reduces downstream project risk.
Detailed engineering
As models become more detailed, coordination between disciplines becomes increasingly important.
Mechanical, structural, electrical, instrumentation, and process engineering teams can review the integrated model together rather than independently.
This collaborative approach improves communication while reducing design conflicts before procurement begins.
Procurement and fabrication
Once equipment has been ordered or fabricated, design flexibility decreases significantly.
VR Design Reviews conducted before procurement help verify:
- Equipment orientation
- Maintenance clearances
- Connection accessibility
- Installation sequencing
- Space allocation
This reduces the likelihood of expensive engineering changes after manufacturing has started.
Construction planning
Construction teams can use immersive reviews to better understand installation sequences and identify logistical challenges before arriving on-site.
This supports:
- Improved schedule planning
- Better contractor coordination
- Reduced field uncertainty
- More efficient construction execution
Commissioning and operations
The value of immersive engineering does not end when construction is complete.
Digital models can continue supporting:
- Operator familiarization
- Maintenance planning
- Asset inspections
- Future modifications
- Brownfield expansions
Organizations increasingly view virtual reality as part of a broader digital engineering strategy rather than a standalone visualization tool.
Which industries benefit most from VR design reviews?
Although virtual reality has applications across many sectors, its greatest value is realized where engineering complexity, operational risk, and project costs are high.
Oil and gas
Oil and gas facilities contain dense process equipment, extensive piping networks, hazardous environments, and strict regulatory requirements. VR Design Reviews help engineering teams improve constructability, maintenance accessibility, and safety while reducing the risk of costly modifications during plant construction or turnarounds.
Process plants and chemical manufacturing
Chemical facilities or process plants require careful coordination between process equipment, utilities, instrumentation, and safety systems. Immersive design validation helps teams identify operational issues before installation while improving HAZOP (Hazard and Operability) discussions and multidisciplinary collaboration.
Power generation
Power plants, including thermal plants, involve large rotating equipment, complex piping systems, electrical infrastructure, and confined maintenance areas. VR enables engineering teams to verify equipment accessibility, lifting paths, and operational workflows before construction begins.
Mining and minerals processing
Mining projects often involve geographically distributed stakeholders and extremely large industrial assets. Virtual reality improves collaboration between engineering consultants, owner-operators, and construction teams by providing a shared understanding of the project before site work starts.
Shipbuilding and marine engineering
Shipbuilding requires precise coordination within highly constrained spaces. Engineering teams use VR design reviews to validate equipment layouts, maintenance access, crew movement, and installation planning before fabrication.
Automotive and advanced manufacturing
Manufacturers use immersive reviews to optimize production lines, robotic work cells, assembly processes, and factory layouts. The ability to evaluate manufacturing workflows before installation helps reduce commissioning time and supports more efficient production ramp-up.
Pharmaceutical and life sciences
Pharmaceutical facilities demand strict compliance, cleanroom validation, and precise equipment placement. VR supports better stakeholder collaboration while helping ensure operational requirements are addressed during design. Across these industries, the common objective remains the same: identify engineering risks before they become construction problems.
Rather than relying solely on drawings or desktop models, organizations are using immersive engineering workflows to improve collaboration, accelerate design decisions, and deliver higher-quality projects with greater confidence.
VR Design Reviews vs. traditional design reviews
Traditional design reviews have helped engineering teams deliver projects for decades. However, as industrial facilities become more complex, the limitations of reviewing drawings and desktop models become increasingly apparent.
Virtual reality does not replace engineering expertise. It enhances how engineering teams understand, validate, and communicate design intent before construction begins.
Traditional Design Reviews | VR Design Reviews |
Review 2D drawings or monitor-based 3D models | Experience the project at true 1:1 scale |
Individual discipline reviews | Collaborative multidisciplinary reviews |
Limited spatial understanding | Natural spatial awareness |
Design intent can be misinterpreted | Shared understanding among all stakeholders |
Issues often discovered during construction | Issues identified during engineering |
Multiple review meetings required | Faster decision-making with all stakeholders present |
Higher probability of rework | Reduced field changes and engineering risk |
The greatest advantage of VR is not visualization alone. It is the ability to improve engineering decisions before they become construction problems.
Best practices for successful VR Design Reviews
Technology alone does not guarantee successful outcomes. Organizations that achieve the greatest value from VR Design Reviews treat them as a structured engineering process rather than a visualization exercise.
Define review objectives before every session
Every review should have a clear purpose.
Examples include:
- Constructability review
- Operability review
- Maintenance review
- Safety validation
- Client approval
- Equipment accessibility
- Installation sequencing
A focused review helps participants evaluate the right aspects of the design instead of attempting to review everything at once.
Include the right stakeholders
Some of the most valuable observations come from people who will eventually build, operate, or maintain the facility.
A multidisciplinary review should typically include:
- Mechanical engineers
- Structural engineers
- Electrical engineers
- Process engineers
- Instrumentation engineers
- Operations representatives
- Maintenance teams
- Construction managers
- Health, Safety, and Environment (HSE) specialists
- Client representatives
Bringing these perspectives together early reduces misunderstandings later in the project.
Review the latest approved model
An outdated model creates confusion and reduces confidence in the review process.
Organizations should establish a single source of truth for engineering data and ensure every participant reviews the same coordinated model.
Capture issues in real time
Every observation should be documented with:
- Location
- Description
- Priority
- Responsible discipline
- Required action
- Target completion date
This transforms a review session into an actionable engineering workflow.
Schedule reviews throughout the project
Waiting until detailed engineering is complete limits the value of Virtual Reality.
Instead, conduct reviews during key project milestones, including:
- Concept design
- Front-End Engineering Design (FEED)
- Detailed engineering
- Pre-fabrication
- Pre-construction
- Pre-commissioning
Continuous validation reduces project uncertainty and minimizes late-stage engineering changes.
Measuring the business value of VR Design Reviews
Engineering leaders are increasingly evaluating digital technologies based on measurable business outcomes rather than technical capabilities.
The return on investment from VR Design Reviews typically comes from preventing problems instead of correcting them.
Organizations commonly report improvements in areas such as:
- Reduced engineering rework
- Faster design approvals
- Improved multidisciplinary coordination
- Fewer Requests for Information (RFIs)
- Lower travel costs through remote collaboration
- Better stakeholder alignment
- More efficient maintenance planning
- Reduced construction delays
According to StartUs Insights, rework accounts for approximately 5% to 15% of total construction costs, with design and coordination issues being among the leading contributors. Reducing even a small percentage of this rework can represent substantial savings on large industrial projects.
Similarly, research published by Stanford Center for Integrated Facility Engineering (CIFE) has consistently demonstrated that improving coordination and collaboration during design contributes to better project performance, reduced waste, and improved schedule reliability.
While every project is unique, the underlying principle remains consistent:
The cost of identifying an engineering issue during design is significantly lower than discovering the same issue during construction or operations.
Why industrial engineering teams are adopting VR Design Reviews
Virtual Reality is no longer viewed as an emerging technology reserved for innovation teams.
It is becoming part of a broader digital engineering strategy that connects design, construction, and operations.
Organizations are adopting VR because it helps them:
- Improve engineering quality
- Strengthen collaboration across distributed teams
- Reduce project risk
- Validate complex facilities before construction
- Support digital transformation initiatives
- Enhance client engagement
- Improve operational readiness
- Increase confidence in engineering decisions
As artificial intelligence, digital twins, building information modeling (BIM), and immersive technologies continue to converge, VR design reviews will play an increasingly important role in modern industrial project delivery.

VR Design Reviews provide engineering teams with a more effective way to validate designs before these risks reach the jobsite.
By combining immersive visualization with multidisciplinary collaboration, organizations can identify issues earlier, improve constructability, enhance safety, and make better engineering decisions throughout the project lifecycle. As industrial facilities continue to grow in complexity, the ability to experience a project before it is built will become a standard engineering practice rather than a competitive advantage.
For organizations pursuing digital engineering, Industrial Extended Reality (XR), and Building Information Modeling (BIM)-driven project delivery, VR Design Reviews are not simply another visualization tool. They are a practical approach to reducing risk, improving quality, and delivering projects with greater confidence.
With platforms like Exxar, engineering teams can transform existing CAD and BIM data into collaborative, immersive experiences that help eliminate costly engineering errors before construction begins.

Mechanical, structural, electrical, instrumentation, and process engineering teams can review the integrated model together rather than independently.
This collaborative approach improves communication while reducing design conflicts before procurement begins.
Procurement and fabrication
Once equipment has been ordered or fabricated, design flexibility decreases significantly.
VR Design Reviews conducted before procurement help verify:
- Equipment orientation
- Maintenance clearances
- Connection accessibility
- Installation sequencing
- Space allocation
This reduces the likelihood of expensive engineering changes after manufacturing has started.
Construction planning
Construction teams can use immersive reviews to better understand installation sequences and identify logistical challenges before arriving on-site.
This supports:
- Improved schedule planning
- Better contractor coordination
- Reduced field uncertainty
- More efficient construction execution
Commissioning and operations
The value of immersive engineering does not end when construction is complete.
Digital models can continue supporting:
- Operator familiarization
- Maintenance planning
- Asset inspections
- Future modifications
- Brownfield expansions
Organizations increasingly view virtual reality as part of a broader digital engineering strategy rather than a standalone visualization tool.
Which industries benefit most from VR design reviews?
Although virtual reality has applications across many sectors, its greatest value is realized where engineering complexity, operational risk, and project costs are high.
Oil and gas
Oil and gas facilities contain dense process equipment, extensive piping networks, hazardous environments, and strict regulatory requirements. VR Design Reviews help engineering teams improve constructability, maintenance accessibility, and safety while reducing the risk of costly modifications during plant construction or turnarounds.
Process plants and chemical manufacturing
Chemical facilities or process plants require careful coordination between process equipment, utilities, instrumentation, and safety systems. Immersive design validation helps teams identify operational issues before installation while improving HAZOP (Hazard and Operability) discussions and multidisciplinary collaboration.
Power generation
Power plants, including thermal plants, involve large rotating equipment, complex piping systems, electrical infrastructure, and confined maintenance areas. VR enables engineering teams to verify equipment accessibility, lifting paths, and operational workflows before construction begins.
Mining and minerals processing
Mining projects often involve geographically distributed stakeholders and extremely large industrial assets. Virtual reality improves collaboration between engineering consultants, owner-operators, and construction teams by providing a shared understanding of the project before site work starts.
Shipbuilding and marine engineering
Shipbuilding requires precise coordination within highly constrained spaces. Engineering teams use VR design reviews to validate equipment layouts, maintenance access, crew movement, and installation planning before fabrication.
Automotive and advanced manufacturing
Manufacturers use immersive reviews to optimize production lines, robotic work cells, assembly processes, and factory layouts. The ability to evaluate manufacturing workflows before installation helps reduce commissioning time and supports more efficient production ramp-up.
Pharmaceutical and life sciences
Pharmaceutical facilities demand strict compliance, cleanroom validation, and precise equipment placement. VR supports better stakeholder collaboration while helping ensure operational requirements are addressed during design. Across these industries, the common objective remains the same: identify engineering risks before they become construction problems.
Rather than relying solely on drawings or desktop models, organizations are using immersive engineering workflows to improve collaboration, accelerate design decisions, and deliver higher-quality projects with greater confidence.
VR Design Reviews vs. traditional design reviews
Traditional design reviews have helped engineering teams deliver projects for decades. However, as industrial facilities become more complex, the limitations of reviewing drawings and desktop models become increasingly apparent.
Virtual reality does not replace engineering expertise. It enhances how engineering teams understand, validate, and communicate design intent before construction begins.
Traditional Design Reviews | VR Design Reviews |
Review 2D drawings or monitor-based 3D models | Experience the project at true 1:1 scale |
Individual discipline reviews | Collaborative multidisciplinary reviews |
Limited spatial understanding | Natural spatial awareness |
Design intent can be misinterpreted | Shared understanding among all stakeholders |
Issues often discovered during construction | Issues identified during engineering |
Multiple review meetings required | Faster decision-making with all stakeholders present |
Higher probability of rework | Reduced field changes and engineering risk |
The greatest advantage of VR is not visualization alone. It is the ability to improve engineering decisions before they become construction problems.
Best practices for successful VR Design Reviews
Technology alone does not guarantee successful outcomes. Organizations that achieve the greatest value from VR Design Reviews treat them as a structured engineering process rather than a visualization exercise.
Define review objectives before every session
Every review should have a clear purpose.
Examples include:
- Constructability review
- Operability review
- Maintenance review
- Safety validation
- Client approval
- Equipment accessibility
- Installation sequencing
A focused review helps participants evaluate the right aspects of the design instead of attempting to review everything at once.
Include the right stakeholders
Some of the most valuable observations come from people who will eventually build, operate, or maintain the facility.
A multidisciplinary review should typically include:
- Mechanical engineers
- Structural engineers
- Electrical engineers
- Process engineers
- Instrumentation engineers
- Operations representatives
- Maintenance teams
- Construction managers
- Health, Safety, and Environment (HSE) specialists
- Client representatives
Bringing these perspectives together early reduces misunderstandings later in the project.
Review the latest approved model
An outdated model creates confusion and reduces confidence in the review process.
Organizations should establish a single source of truth for engineering data and ensure every participant reviews the same coordinated model.
Capture issues in real time
Every observation should be documented with:
- Location
- Description
- Priority
- Responsible discipline
- Required action
- Target completion date
This transforms a review session into an actionable engineering workflow.
Schedule reviews throughout the project
Waiting until detailed engineering is complete limits the value of Virtual Reality.
Instead, conduct reviews during key project milestones, including:
- Concept design
- Front-End Engineering Design (FEED)
- Detailed engineering
- Pre-fabrication
- Pre-construction
- Pre-commissioning
Continuous validation reduces project uncertainty and minimizes late-stage engineering changes.
Measuring the business value of VR Design Reviews
Engineering leaders are increasingly evaluating digital technologies based on measurable business outcomes rather than technical capabilities.
The return on investment from VR Design Reviews typically comes from preventing problems instead of correcting them.
Organizations commonly report improvements in areas such as:
- Reduced engineering rework
- Faster design approvals
- Improved multidisciplinary coordination
- Fewer Requests for Information (RFIs)
- Lower travel costs through remote collaboration
- Better stakeholder alignment
- More efficient maintenance planning
- Reduced construction delays
According to StartUs Insights, rework accounts for approximately 5% to 15% of total construction costs, with design and coordination issues being among the leading contributors. Reducing even a small percentage of this rework can represent substantial savings on large industrial projects.
Similarly, research published by Stanford Center for Integrated Facility Engineering (CIFE) has consistently demonstrated that improving coordination and collaboration during design contributes to better project performance, reduced waste, and improved schedule reliability.
While every project is unique, the underlying principle remains consistent:
The cost of identifying an engineering issue during design is significantly lower than discovering the same issue during construction or operations.
Why industrial engineering teams are adopting VR Design Reviews
Virtual Reality is no longer viewed as an emerging technology reserved for innovation teams.
It is becoming part of a broader digital engineering strategy that connects design, construction, and operations.
Organizations are adopting VR because it helps them:
- Improve engineering quality
- Strengthen collaboration across distributed teams
- Reduce project risk
- Validate complex facilities before construction
- Support digital transformation initiatives
- Enhance client engagement
- Improve operational readiness
- Increase confidence in engineering decisions
As artificial intelligence, digital twins, building information modeling (BIM), and immersive technologies continue to converge, VR design reviews will play an increasingly important role in modern industrial project delivery.

Conclusion
Engineering errors become exponentially more expensive as projects move from design to construction. Every unresolved clash, inaccessible valve, poorly positioned piece of equipment, or overlooked maintenance issue increases the likelihood of rework, delays, and additional project costs. VR Design Reviews provide engineering teams with a more effective way to validate designs before these risks reach the jobsite.
By combining immersive visualization with multidisciplinary collaboration, organizations can identify issues earlier, improve constructability, enhance safety, and make better engineering decisions throughout the project lifecycle. As industrial facilities continue to grow in complexity, the ability to experience a project before it is built will become a standard engineering practice rather than a competitive advantage.
For organizations pursuing digital engineering, Industrial Extended Reality (XR), and Building Information Modeling (BIM)-driven project delivery, VR Design Reviews are not simply another visualization tool. They are a practical approach to reducing risk, improving quality, and delivering projects with greater confidence.
With platforms like Exxar, engineering teams can transform existing CAD and BIM data into collaborative, immersive experiences that help eliminate costly engineering errors before construction begins.
