Why Process Plants Are Adopting 1:1 Scale VR Design Reviews Before Turnarounds and Expansions
Why Process Plants Are Adopting 1:1 Scale VR Design Reviews Before Turnarounds and Expansions
Every turnaround or plant expansion is a race against time. Engineering teams have a limited window to execute complex work, minimize production losses, maintain safety, and bring facilities back online as planned. A single design oversight can lead to unexpected field modifications, schedule delays, additional contractor hours, and extended downtime that impacts millions of dollars in production.
This is why more process plants are adopting 1:1 scale Virtual Reality (VR) design reviews before construction, maintenance turnarounds, and brownfield expansions. Instead of reviewing three-dimensional (3D) models on a desktop monitor, engineers, operators, maintenance teams, contractors, and project stakeholders can walk through a full-scale virtual replica of the facility. They experience equipment layouts, piping, access routes, and maintenance clearances exactly as they will exist in the real plant.
The shift is not about replacing traditional engineering workflows. It is about making design reviews more effective by identifying issues while changes are still inexpensive. When multidisciplinary teams can validate constructability, maintainability, and operator access before fabrication begins, projects move into execution with greater confidence and significantly lower risk.
According to the National Institute of Standards and Technology (NIST), inadequate interoperability and inefficient information exchange continue to contribute to billions of dollars in avoidable costs across capital facility industries. Improving collaboration and early design validation directly addresses many of these inefficiencies.
For engineering, procurement, and construction (EPC) companies and owner-operators, immersive VR has evolved from a visualization tool into a practical decision-making platform that supports safer, faster, and more predictable project delivery.
What is a 1:1 scale VR design review?
A 1:1 scale VR design review is an immersive engineering review where a Building Information Modeling (BIM) model or Computer-Aided Design (CAD) model is experienced at its actual physical size using Virtual Reality.
Rather than rotating a model on a computer screen, project teams can walk through the plant, inspect equipment from different viewpoints, evaluate working spaces, and interact with the environment as if construction were already complete.
This changes how design decisions are made because people naturally understand space at full scale. Typical activities during a VR design review include:
- Reviewing piping layouts and equipment positioning
- Validating maintenance and service access
- Checking operator visibility and reachability
- Evaluating crane and lifting clearances
- Identifying clashes between disciplines
- Assessing emergency evacuation routes
- Reviewing construction sequencing
- Capturing design comments collaboratively
For complex industrial facilities such as refineries, chemical plants, pharmaceutical manufacturing facilities, power generation plants, and oil and gas assets, these reviews provide insights that are difficult to achieve using drawings or desktop-based model reviews alone.
Traditional design review | 1:1 scale VR design review |
Two-dimensional drawings and desktop models | Immersive full-scale environment |
Limited perception of space | True understanding of spatial relationships |
Discipline-specific reviews | Multi-disciplinary collaboration |
Difficult for non-design stakeholders | Easy for operations and maintenance teams to participate |
Issues often discovered during construction | Issues identified before fabrication and installation |
The value of VR is not that engineers can “see” the model. They already do that. The value lies in allowing every stakeholder to experience how the facility will function before physical work begins.
Why are process plants adopting VR before turnarounds?
A turnaround is one of the most expensive operational events in a process plant. Every additional hour of downtime affects production, contractor costs, equipment availability, and project budgets.
During these projects, engineering decisions made months earlier directly influence execution success.
Traditional review methods often struggle to answer practical questions such as:
- Can technicians safely remove this valve?
- Is there enough clearance to extract a heat exchanger bundle?
- Will temporary scaffolding block another work area?
- Can operators safely reach emergency shutoff systems?
- Is there sufficient access for lifting equipment?
- Will new piping interfere with existing infrastructure?
These questions are easier to answer when stakeholders experience the design at full scale.
Instead of discovering problems during installation, teams identify them while modifications still exist only in the digital model.
This proactive approach reduces uncertainty throughout the project lifecycle.
Finding design conflicts before they become field problems
Process plants are among the most spatially complex industrial environments. Multiple engineering disciplines contribute to the same facility, including structural, mechanical, piping, instrumentation, electrical, civil, and operations teams.
Even when every discipline produces accurate designs, conflicts can still occur because individual models do not always reveal how components interact in physical space.
An immersive review allows project teams to validate:
- Pipe routing
- Equipment spacing
- Structural interference
- Cable tray placement
- Maintenance access
- Safety clearances
- Operator movement paths
Research published by Stanford University’s Center for Integrated Facility Engineering (CIFE) has demonstrated that immersive Virtual Reality environments improve stakeholders’ ability to detect spatial issues compared with traditional desktop reviews, particularly for complex facility projects.
Detecting these issues during design can prevent costly Requests for Information (RFIs), field engineering changes, and construction rework later in the project.
How does VR improve turnaround planning?
Successful turnarounds depend on preparation rather than reaction.
Months before the shutdown begins, engineering teams finalize designs, procurement schedules, contractor planning, and work packages. If hidden design issues emerge during execution, the impact can cascade across the entire schedule.
Immersive VR enables project teams to validate much more than geometry.
They can evaluate how work will actually be performed inside the plant.
Engineering teams can validate constructability
Constructability reviews determine whether designs can be built safely and efficiently.
Within a virtual environment, engineers can verify:
- Installation sequences
- Material movement paths
- Equipment lifting strategies
- Temporary work areas
- Access for specialized tools
- Crane positioning
Potential constraints become visible before crews arrive on site.
Maintenance teams can verify maintainability
One of the biggest advantages of involving maintenance personnel early is that they understand how equipment behaves throughout its operational lifecycle.
During VR reviews, maintenance teams can assess whether there is adequate space to:
- Remove pumps
- Replace motors
- Service valves
- Inspect pressure vessels
- Access instrumentation
- Perform routine maintenance safely
These practical observations often uncover issues that engineering drawings alone cannot communicate effectively.
Instead of redesigning systems after installation, teams improve maintainability while the project remains in the design phase.
Operations teams contribute earlier
Operators possess valuable knowledge about plant workflows that is difficult to capture through documentation alone.
Walking through a full-scale digital plant allows them to identify operational concerns related to:
- Line of sight
- Control access
- Emergency response
- Human movement
- Equipment accessibility
- Safe operating procedures
Their feedback helps create facilities that are not only technically correct but also easier and safer to operate over the long term.
How does VR improve plant expansion planning?
Unlike greenfield projects, most process plant expansions happen in brownfield environments where new infrastructure must fit within an operating facility. Existing process equipment, structural steel, underground utilities, and active production areas leave very little room for error.
While Building Information Modeling (BIM) and Computer-Aided Design (CAD) provide accurate digital models, understanding how those designs perform in the real world is a different challenge. Engineers often discover conflicts only when construction begins or equipment arrives on site.
A 1:1 scale VR design review bridges that gap by allowing multidisciplinary teams to experience the expansion before fabrication starts.
Instead of asking whether a model is technically correct, stakeholders can ask whether it is practical to build, operate, and maintain.
Brownfield projects demand better spatial validation
Brownfield expansions introduce challenges that rarely exist in new facilities.
These include:
- Connecting new piping with existing process lines
- Installing equipment in congested areas
- Maintaining safe access during construction
- Protecting operating assets
- Planning temporary shutdown activities
- Coordinating multiple contractors simultaneously
An immersive walkthrough gives project teams confidence that every discipline is working toward the same objective before construction begins.
Engineering decisions become operational decisions
One of the biggest advantages of immersive reviews is that they involve people beyond the engineering department.
During a design review, participants can include:
- Process engineers
- Mechanical engineers
- Operations managers
- Maintenance supervisors
- Health, Safety, and Environment (HSE) specialists
- Construction managers
- Contractors
- Plant leadership
This collaborative approach helps eliminate assumptions that often appear when teams review drawings independently.
Instead of exchanging dozens of review comments through emails and markups, stakeholders discuss issues together while standing inside the same virtual environment.
The result is faster decision-making and fewer late-stage design revisions.
What design issues can a 1:1 scale VR review identify?
Every process plant has unique operational requirements, but several categories of issues appear repeatedly during immersive design reviews.
Equipment accessibility
An equipment layout may satisfy design standards while still making maintenance difficult.
A VR walkthrough allows teams to verify:
- Whether valves can be reached safely
- Pump removal paths
- Heat exchanger maintenance clearance
- Instrument accessibility
- Operator visibility
- Control panel reachability
Small improvements during design can eliminate years of operational inconvenience.
Human factors and ergonomics
Industrial facilities are designed for people as much as they are for equipment.
Virtual Reality helps evaluate:
- Walking paths
- Working posture
- Reach distance
- Operator comfort
- Visibility around equipment
- Safe movement during maintenance
This supports better human-centered engineering and reduces the likelihood of operational hazards.
Constructability risks
Construction teams can review whether installation activities are practical before work starts.
Examples include:
- Crane access limitations
- Pipe installation sequencing
- Temporary support requirements
- Material movement routes
- Equipment lifting constraints
- Scaffold placement
Addressing these issues early reduces the number of field modifications during execution.
Safety and emergency preparedness
Safety reviews become more realistic in an immersive environment.
Teams can validate:
- Emergency escape routes
- Fire equipment accessibility
- Isolation valve locations
- Safe working clearances
- Hazardous area access
- Maintenance safety procedures
These reviews complement established engineering practices or MEP trades such as Hazard Identification (HAZID), HVAC, and Hazard and Operability Study (HAZOP) by making design intent easier to understand across disciplines.
What is the business value of immersive VR design reviews?
The objective of a VR design review is not simply to create a better visualization.
Its purpose is to improve project outcomes.
Organizations investing in immersive engineering reviews typically focus on measurable business improvements across the project lifecycle.
These include:
- Fewer construction changes
- Reduced engineering rework
- Better multidisciplinary coordination
- Faster stakeholder approvals
- Improved maintenance planning
- Better operator readiness
- Lower project risk
- Greater confidence before procurement and fabrication
According to TechViz, citing industry findings reported by XR Today, immersive Virtual Reality can accelerate aspects of product design while improving collaboration between engineering teams. Although project outcomes vary, the consistent advantage comes from identifying issues earlier when they are significantly less expensive to resolve.
Similarly, research from the Construction Industry Institute (CII) has consistently shown that improving front-end planning and design quality contributes to stronger cost and schedule performance across capital projects.
For process plants, this translates into a straightforward principle.
The earlier a problem is identified, the lower the cost of correcting it.
How does VR complement Digital Twins, BIM, and CAD?
A common misconception is that Virtual Reality replaces existing engineering systems.
In reality, VR extends their value.
Engineering teams already invest heavily in:
- Computer-Aided Design (CAD)
- Building Information Modeling (BIM)
- Laser scanning
- Point cloud data
- Digital Twins
- Engineering data management platforms
Virtual Reality transforms these engineering assets into an interactive environment where project teams can review designs together.
Instead of examining isolated drawings or rotating models on a desktop screen, stakeholders experience the project from the perspective of the people who will eventually build, operate, and maintain it. This makes technical information easier to interpret while improving communication between engineering and operations.
For owner-operators managing multiple facilities across different locations, immersive collaboration also enables geographically distributed teams to participate in the same design review without requiring everyone to travel to the project site. As industrial projects become larger and more complex, this level of collaboration is becoming an operational advantage rather than a technological luxury.
Why leading engineering organizations are making immersive reviews part of project delivery
The role of Virtual Reality has changed significantly over the past decade. Early adoption focused primarily on visualization and client presentations. Today’s leading industrial organizations use immersive reviews much earlier in the project lifecycle.
They support activities such as:
- Front-End Engineering Design (FEED)
- Design validation
- Constructability reviews
- Operability assessments
- Maintainability evaluations
- Safety reviews
- Contractor coordination
- Executive design approvals
This shift reflects a broader change in engineering strategy.
Organizations are no longer adopting VR because it is innovative.
They are adopting it because it helps teams make better decisions before those decisions become expensive to change.
For process plants planning major turnarounds, revamps, debottlenecking projects, or capacity expansions, that capability can directly influence project certainty, operational readiness, and long-term asset performance.
Frequently asked questions about 1:1 scale VR design reviews
Both methods have their place, but they serve different purposes.
Desktop reviews are effective for developing and modifying designs. A 1:1 scale VR review helps teams understand how those designs will function in a real-world environment. Engineers, operators, maintenance personnel, and project managers can evaluate space, accessibility, visibility, and workflows in ways that are difficult to achieve on a traditional monitor.
Yes. Brownfield facilities often have limited space, aging infrastructure, and ongoing operations that increase project complexity. VR helps teams validate equipment placement, piping routes, maintenance access, and construction sequencing before work begins, reducing the likelihood of field conflicts.
No. VR complements existing engineering workflows.
Building Information Modeling (BIM) and Computer-Aided Design (CAD) remain the foundation for engineering design. VR provides an immersive environment where project stakeholders can review and validate those models together, improving communication and decision-making.
The greatest value comes before procurement, fabrication, and construction.
Many organizations incorporate immersive reviews during:
- Front-End Engineering Design (FEED)
- Detailed engineering
- Constructability reviews
- Hazard and Operability Study (HAZOP) workshops
- Design freeze milestones
- Turnaround planning
- Brownfield expansion projects
Early validation gives engineering teams more flexibility to resolve issues while design changes are still relatively inexpensive.
Industries managing complex industrial assets typically realize the greatest value, including:
- Oil and gas
- Chemical processing
- Petrochemicals
- Power generation
- Pharmaceutical manufacturing
- Mining and metals
- Water treatment
- Food and beverage manufacturing
- Engineering, Procurement, and Construction (EPC) projects
Any project involving dense layouts, multiple engineering disciplines, or high-cost shutdowns can benefit from immersive design validation.
Why immersive design reviews are becoming a standard engineering practice
Industrial projects continue to grow in scale and complexity. At the same time, organizations face increasing pressure to improve safety, reduce capital expenditure, shorten project schedules, and minimize operational disruptions.
Traditional design reviews remain an essential part of engineering. However, they often struggle to communicate how a facility will actually function once construction is complete. A 1:1 scale VR design review addresses this challenge by enabling project stakeholders to experience the facility before physical work begins.
Instead of reacting to problems in the field, teams can identify and resolve them during design.
This shift supports better engineering decisions throughout the project lifecycle by improving:
- Design quality
- Cross-functional collaboration
- Constructability
- Maintainability
- Operator readiness
- Safety planning
- Project certainty
As Digital Twins, laser scanning, and intelligent engineering platforms become more common across the process industry, immersive design reviews are increasingly becoming a natural extension of modern engineering workflows rather than a standalone technology.
Organizations that validate designs earlier are often better positioned to deliver projects with fewer surprises during construction and commissioning.

Every design decision made before a turnaround or expansion influences project cost, schedule, safety, and long-term operability. A 1:1 scale VR design review gives your engineering, operations, and maintenance teams the confidence to identify issues early, align stakeholders, and execute projects with fewer surprises.
See how Exxar helps industrial organizations transform CAD and BIM models into immersive engineering reviews that improve constructability, maintainability, and project collaboration.
