Choose AAegis when you need an enterprise airport twin that unifies BIM/CAD/GIS and live sensor data for operations, lifecycle management, and predictive maintenance. For BIM+IoT engineering workflows use Bentley iTwin; for maintenance tracking choose Oxmaint.
Best when you need engineering-grade BIM+GIS+IoT integration and an 'evergreen' real‑time model for predictive maintenance, pavement and airside management across operations.
Managing airport infrastructure requires unifying massive amounts of spatial, operational, and IoT data—from terminal facilities and baggage systems to active runways. Several prominent digital twin platforms and enterprise software solutions specialize in or actively power airport infrastructure deployments:
WillowTwin by Willow : Widely recognized for large-scale infrastructure deployments (such as at Dallas/Fort Worth International Airport), it integrates BIM (Building Information Modeling), GIS, and real-time operational data for terminals and airfields.
Bentley iTwin Platform : A heavy-hitter in infrastructure engineering, Bentley’s platform allows teams to incorporate engineering data into a living digital twin to monitor structural health, asset lifecycles, and facility changes.
Autodesk Tandem : Autodesk’s cloud-based digital twin platform connects facility asset data with BIM models specifically to help operations teams streamline handover, track performance, and reduce downtime.
Esri ArcGIS : Excellent for marrying GIS mapping with facility management, providing strong spatial context for massive airport footprints, runways, and surrounding landside/airside infrastructure.
AWS IoT TwinMaker : A flexible cloud tool by Amazon Web Services that lets you build digital twins of real-world systems by combining existing video, sensor data, and spatial records.
If you'd like, let me know:
Are you focusing more on landside/terminal infrastructure or airside assets (runways, gates, baggage systems)?
Do you already have existing BIM/GIS models , or are you starting from scratch?
I can help narrow down which platform fits your technical stack and project scope.
Yes. I found several credible options, but they fall into slightly different categories. If your priority is managing airport infrastructure and assets across the lifecycle, rather than just simulating passenger/airside operations, I’d put these on the shortlist:
Engineering/3D infrastructure twin combining BIM, GIS, reality models and operational data
Engineering, capital projects, facilities and asset lifecycle
dRofus dTwin
Very strong
BIM + FM + IoT + asset/operational data
Lifecycle management from design/handover through operations
Smart Spatial
Strong
High-fidelity 3D operational twin with live system/sensor feeds
Real-time airport operations and infrastructure monitoring
SAIM
Strong
CMMS/EAM + 3D digital twin + monitoring
Maintenance, inspections and asset management
AWS IoT TwinMaker
Flexible/platform
Build-your-own twin from IoT, BMS, BIM/3D and enterprise data
Airports wanting to build a highly customized cloud twin
1.
This is probably the closest match to a purpose-built airport infrastructure digital-twin foundation.
Esri explicitly positions ArcGIS as a foundation for airport “living digital twins.” It can represent airfield assets, terminals, buildings, utilities/underground infrastructure, landside transportation and support facilities, while connecting asset management, work orders, inspections and operational data.
A particularly compelling aspect is that there are real airport implementations. SFO, for example, has integrated GIS and IoT into an airport “Dynamic Twin” covering hundreds of thousands of assets; Esri also documents implementations at Pittsburgh, Miami, Denver and other airports.
Strong fit if you need:
Airport-wide asset registry
GIS + BIM integration
Facilities and infrastructure management
Utilities and underground assets
Airfield/runway infrastructure
Maintenance/work-order integration
Indoor terminal digital twins
Real-time IoT feeds
FAA/airfield GIS workflows
2.
Bentley is particularly interesting if your airport infrastructure program is heavily engineering/BIM/construction oriented.
Its airport offering connects engineering, GIS, reality models and operational information into a digital twin, covering terminals, concourses, runways, taxiways and aprons. It also supports 4D construction simulation, project delivery/handover and connected asset monitoring.
There is also a concrete Sydney Airport implementation: Sydney uses Bentley iTwin Experience and related Bentley technologies for its MAPS@SYD spatial platform. Bentley reports that the system provides access to above- and below-ground airport assets and has evolved toward a digital twin.
Strong fit if you need:
BIM/engineering-centric twin
Capital-project integration
As-built/reality capture
3D infrastructure
Construction-to-operations handover
Asset visualization and lifecycle information
3.
This one is worth investigating if your main objective is lifecycle asset information, particularly the transition from airport projects into operations.
dRofus specifically markets its dTwin for airports and describes connecting BIM, facilities management, IoT, asset and operational data. It also highlights asset/equipment lifecycle tracking and airport-specific security/governance requirements.
Importantly, dRofus cites Auckland Airport and Vienna Airport in its airport deployments.
This is more focused on the real-time operational twin side. Its airport platform brings together building systems such as HVAC, lighting, power and backup systems with passenger/vehicle flows and other operational data in a 3D environment. It also advertises live data ingestion, system/sensor integration, simulation and geospatial alarming.
I'd investigate this particularly if you're interested in an airport operations center / common operating picture rather than primarily an asset-information repository.
SAIM is more EAM/CMMS-oriented, with digital-twin/3D capabilities layered around maintenance, inspections, asset management and monitoring. Its aviation offering is specifically targeted at airports and other aviation organizations.
That makes it interesting if your starting point is maintenance and asset reliability, rather than BIM/GIS.
AWS takes a different approach: rather than selling you an airport-specific packaged application, AWS provides an architecture for building the twin on its cloud platform.
Its reference architecture combines BMS, baggage systems, passenger-flow sensors, cameras, predictive analytics, airport operational data and 3D models using services including IoT TwinMaker.
This is attractive if you have a strong internal technology team and want to build a highly customized airport twin, but it means more integration/implementation work than buying a specialized airport application.
How I'd narrow it down
For airport infrastructure management specifically, I'd investigate these three first:
1. Esri ArcGIS — if the twin needs to become the airport's enterprise spatial/asset system of record.
2. Bentley iTwin — if the airport is heavily invested in BIM, engineering, capital projects and 3D infrastructure information.
3. dRofus dTwin — if the primary challenge is maintaining reliable asset information from planning/design through handover and facilities operations.
There's actually an important architectural distinction here: Esri and Bentley are not necessarily mutually exclusive. A sophisticated airport can use GIS as the enterprise spatial layer, BIM/engineering platforms for detailed models, an EAM/CMMS for maintenance, and a digital-twin layer to connect them. SFO's architecture is an example of this sort of multi-system integration.
If you tell me whether you're looking at this from the perspective of (a) an airport owner/operator, (b) an infrastructure/engineering company, or (c) a software procurement/investment decision, I can narrow this to 5–7 vendors and produce a detailed feature/architecture/pricing/airport-customer comparison.
When managing airport infrastructure—ranging from active runways and terminal buildings to baggage handling and passenger flow—several enterprise digital twin platforms specialize in aviation and smart infrastructure ecosystems.
Top digital twin platforms used for airport infrastructure include:
WillowTwin by Willow : Widely deployed for major aviation hubs (such as Dallas/Fort Worth International Airport). It integrates BIM (Building Information Modeling), GIS (Geographic Information Systems), and real-time IoT sensor data into a centralized operational dashboard for terminals and airfields.
Bentley Systems iTwin : An infrastructure engineering digital twin platform that allows airports to incorporate engineering data, CAD, and reality modeling to monitor structural health, construction progress, and facility maintenance.
Esri ArcGIS : While fundamentally a GIS leader, Esri's geospatial digital twin capabilities are heavily leveraged by airports for spatial asset management, airside/landside mapping, and tracking environmental or surface operations.
AWS IoT TwinMaker : A flexible cloud-based framework by Amazon Web Services that helps build digital twins of real-world systems like baggage handling lines, HVAC, and power grids by connecting existing video feeds, IoT data, and historical records.
SITA Smart Airport / SITA Digital Flex : Focuses heavily on the operational, passenger-flow, and baggage side of the airport digital ecosystem, integrating airport management systems with predictive visual data.
OXmaint Digital Twin : Tailored specifically for infrastructure maintenance optimization, connecting BIM models and asset registers with predictive maintenance workflows.
To help narrow down the ideal platform, let me know:
Are you focusing more on airside infrastructure (runways, taxiways) or landside/terminals (gates, baggage, HVAC, retail spaces)?
Do you already have existing BIM models or GIS data mapped out?
Yes. I found several credible options, but they differ substantially in whether they are airport-specific products versus broader infrastructure platforms that have strong airport implementations.
IoT, predictive maintenance, asset monitoring and maintenance workflows
x-Spatial
Airport-specific services/platform approach
GIS/BIM/CAD integration, facilities and infrastructure asset management
1. Bentley Systems — iTwin
This is probably the closest match if you mean a true infrastructure digital-twin platform, rather than just an airport facilities-management system.
Bentley's airport offering covers terminals, concourses, runways, taxiways, aprons, utilities, roads and other airport infrastructure. Its iTwin platform can combine BIM/CAD, GIS, reality meshes, IoT/sensor information, schedules and enterprise data.
A particularly relevant reference is Sydney Airport, where Bentley describes using a map-based digital twin to manage assets ranging from terminals and car parks to individual doors and utility infrastructure.
ArcGIS is another particularly strong candidate if your priority is managing the airport as a geographic/asset system of record.
Esri explicitly positions ArcGIS as a foundation for airport digital twins, covering airside and landside assets, terminal/building infrastructure, utilities, ground transportation and support facilities. It can integrate asset-management/work-order systems and provide spatial views of maintenance, inspections and asset condition.
It also supports bringing BIM models into the real-world airport context and connecting real-time operational/asset data.
This is worth looking at if you want something specifically packaged around airport operations, rather than assembling a digital-twin stack yourself.
Desapex describes an airport twin that combines an as-built digital model, asset lifecycle/maintenance information, terminal and airside equipment, space/tenant management, passenger-flow information and energy performance.
OXmaint is positioning a newer platform specifically around airport infrastructure + predictive maintenance. Its stated architecture combines BIM/IFC, GIS and 3D asset models with IoT/SCADA/BACnet data and maintenance records.
I'd treat this as a platform worth evaluating alongside the larger established ecosystems rather than assuming equivalent market maturity.
What I'd investigate first
If your requirement is something like:
"One digital representation of the entire airport campus that engineering, facilities, maintenance and operations can use to understand assets, their location, condition and lifecycle."
I'd put Bentley iTwin and Esri ArcGIS at the top of the initial evaluation, with Desapex as the airport-specific alternative.
The distinction is important:
Bentley → strongest orientation toward engineering/BIM/infrastructure lifecycle + digital twin
Desapex → more directly packaged as an airport operational digital twin
OXmaint → particularly interesting for maintenance/IoT/predictive analytics
If you tell me whether you're looking for (a) an off-the-shelf airport operator platform, (b) a platform on which to build your own digital twin, or (c) software for a specific airport asset class such as terminals, runways, utilities or baggage systems, I can narrow this to 5–10 vendors and compare features, integrations, deployment model, likely pricing approach, and actual airport references.
Yes. There are several platforms that fit, but they fall into two different categories: airport infrastructure/asset-management twins and airport operational simulation twins.

My read
If by “managing airport infrastructure” you mean something like:
“I need a persistent digital representation of the entire airport campus, tied to BIM/GIS/asset IDs, facilities, utilities, maintenance, construction and sensor data.”
then Bentley iTwin and Esri ArcGIS are the two platforms I'd investigate first.
Bentley is particularly interesting if your organization has a substantial engineering/BIM/construction workflow. Its airport offering explicitly describes connecting engineering, GIS and operational data into a digital twin and extending that into asset maintenance and monitoring.
Esri is particularly interesting if the center of gravity is airport GIS, facilities, asset inventory, work orders and spatial operations. Esri describes ArcGIS as a foundation for “living digital twins” of airports and specifically covers airfield, terminal, utility, landside and other infrastructure assets.
One important distinction: Autonoma is more about simulating the airport and testing future scenarios than being the system of record for infrastructure assets.
If you're looking for a specific type of platform
I can narrow this considerably if your use case is one of these:
If you tell me which of these you need, I can produce a shortlist of 5–10 actual vendors with capabilities, integrations, deployment model, and example airports using them.
Leading digital twin platforms for airport infrastructure management includeBentley Systems iTwin, Willow Inc., Esri ArcGIS , and Autodesk Tandem . These platforms construct dynamic virtual replicas of physical runways, terminals, baggage systems, and MEP (mechanical, electrical, plumbing) networks to optimize operations.
Top Digital Twin Platforms for Airports
Bentley Systems iTwin : Excellent for large-scale civil infrastructure, integrating 3D/4D BIM (Building Information Modeling) models with engineering data to track structural health, runways, and taxiways.
Willow Inc. : Specializes in real-time operational intelligence, combining IoT sensor data with spatial data to manage smart buildings, energy performance, and equipment maintenance inside major hubs like DFW.
Esri ArcGIS : Focuses heavily on geospatial mapping, GIS data integration, and land-side/air-side asset management across massive airport acreage.
Autodesk Tandem : A cloud-based facility digital twin platform utilized for turning construction and BIM data into a live operational tool for facility and asset management teams.
Key Infrastructure Focus Areas
When deploying an airport digital twin, platforms are typically configured to target high-consequence systems:
Airfield Assets : Runways, taxiways, and precision airfield lighting.
If your focus is airport infrastructure management—terminals, airfield assets, utilities, BIM/GIS, construction projects, maintenance, and lifecycle information—I’d shortlist a few platforms rather than looking for a generic “digital twin” product.
Platforms worth evaluating
Platform
Best fit
Airport infrastructure capabilities
Bentley Systems iTwin / Bentley Infrastructure Cloud
Airport facilities, airfield assets, utilities, BIM integration, work orders, inspections, dashboards and living digital twins
Dassault Systèmes 3DEXPERIENCE / DELMIA
Simulation + operational virtual twin
Airport design, passenger/vehicle flows, maintenance, operational simulation, commissioning and optimization
Desapex Airport Operations Digital Twin
Airport-specific operational twin
As-built BIM plus gates, tenants, passenger-processing equipment, baggage systems, utilities and lifecycle/maintenance data
Bentley's iTwin Platform is particularly explicitly designed as an infrastructure digital-twin platform: it can combine BIM/CAD, GIS, reality capture, IoT/sensor and enterprise data, with APIs for building applications around the twin.
There is also unusually direct airport evidence for Bentley. Sydney Airport has used Bentley iTwin/OpenCities to develop MAPS@SYD, a unified spatial-data environment; Bentley reports that the system saves the spatial team roughly 65 resource-hours per week and is being developed toward a fuller digital twin. Bentley Bentley also documents airport use cases involving terminals, car parks, doors, utilities and other infrastructure assets.
Esri ArcGIS is compelling if your airport's system of record is fundamentally geospatial. Its airport offering combines BIM and GIS, asset/facility information, work orders, maintenance, inspections and operational data, and Esri explicitly positions this as the basis for airport digital twins.
Dassault Systèmes takes a somewhat different approach: its Airport Experience uses the 3DEXPERIENCE platform and virtual-twin technology to simulate airport design and flows, maintenance and operational readiness, rather than primarily being an infrastructure asset/GIS platform.
What I'd put in an airport RFP
I'd evaluate candidates against these capabilities:
BIM/CAD: Revit, IFC, Bentley, Civil 3D, etc.
GIS: indoor/outdoor mapping, coordinates, spatial relationships and underground utilities
Asset registry: unique IDs for buildings, gates, baggage systems, MEP, pavement, lighting, utilities, etc.
Reality capture: LiDAR, photogrammetry, drone imagery and point clouds
Asset lifecycle: condition, inspections, maintenance, warranties and replacement planning
Construction → operations handover: preserving the as-designed/as-built information
Real-time integration: BMS, IoT sensors, SCADA, baggage, passenger-flow and other operational systems
4D/5D: construction sequencing, schedule and cost
Scenario simulation: terminal expansion, utility changes, passenger flows and disruptions
Open APIs/data: ability to avoid creating another silo
Security and permissions: especially important for airside and critical infrastructure
Mobile/field workflows: technicians should be able to find and update assets in the field
Portfolio scale: ability to represent the entire airport campus rather than one building
A useful distinction is “3D model” vs. “operational digital twin.” For an airport, I'd want the latter: a persistent representation connecting BIM + GIS + asset information + real-world condition + operational systems, rather than simply a navigable 3D model. Research on airport asset-management architectures similarly identifies BIM-based lifecycle information integration as a foundation for an airport digital twin.
If you tell me whether you're an airport owner/operator, engineering consultant, or technology vendor—and roughly how large the airport is—I can narrow this to 3–5 platforms and compare their architecture, integrations, implementation approach, and likely fit for your use case.
Managing airport infrastructure through a digital twin requires a platform capable of unifying massive spatial datasets (BIM/CAD for terminals, GIS for airfields/landside) with real-time operational streams (IoT sensors, flight data, maintenance logs).
Leading enterprise platforms actively used or tailored for airport infrastructure management include:
Autodesk Tandem
Best for: Facility operations, asset lifecycle management, and connecting BIM (Revit/Civil 3D) data directly to operational insights.
Key Capabilities: Enables major hubs (like Denver International Airport) to aggregate hundreds of distinct mechanical, electrical, HVAC, and structural models into a single navigable, cloud-based digital twin. It doesn't replace your CMMS (Computerized Maintenance Management System) or IoT manager; instead, it acts as a central pane-of-glass to visualize asset health, track operational parameters, and streamline facility coordination . Learn more on Autodesk Tandem.
Bentley Systems (iTwin Experience / SYNCHRO)
Best for: Large-scale infrastructure engineering, 4D construction sequencing, and massive asset registries (terminals, car parks, and airfield utilities).
Key Capabilities: Used by heavy infrastructure environments like Sydney Airport to manage complex asset hierarchies (e.g., tracking tens of thousands of individual doors, tenancies, and spatial elements with unique IDs). Bentley's iTwin platform integrates GIS and reality modeling, while SYNCHRO 4D helps plan and simulate massive structural expansions or active airfield construction constraints. Explore solutions via Bentley Systems.
Esri ArcGIS (Geospatial Digital Twins)
Best for: Landside/airfield mapping, environmental monitoring, spatial analysis, and connecting GIS with IoT data streams.
Key Capabilities: Often acts as the geographic backbone for airports (integrated alongside tools like Microsoft Azure Digital Twins). It excels at mapping runways, perimeter security, pavement management, and geographic asset tracking where GPS and spatial context are paramount. Discover mapping capabilities on Esri ArcGIS.
Microsoft Azure Digital Twins + Partner Ecosystem
Best for: Custom, highly scalable enterprise IoT data integration.
Key Capabilities: Azure provides the underlying spatial graph engine used by system integrators and consultants (like Parsons) at major airports (such as DFW) to ingest live weather data, runway sensor metrics, and baggage system telemetry into a unified cloud backend. Check out the technical framework via Microsoft Azure Digital Twins.
To help narrow down the right platform, let me know:
Are you focusing more on terminal facilities (HVAC, baggage, interiors) or airfield/landside infrastructure (runways, GIS mapping, utilities)?
Do you need an out-of-the-box SaaS solution or a custom cloud integration that hooks into your existing enterprise software (like Maximo or Infor EAM)?
When managing airport infrastructure through a digital twin, platforms need to integrate spatial data (BIM/CAD/GIS) with real-time IoT, building management systems (BMS), and maintenance workflows (CMMS/EAM).
Top platforms and technology ecosystems specializing in or frequently deployed for airport infrastructure digital twins include:
Bentley Systems : Known for its iTwin Platform , Bentley specializes in infrastructure engineering and heavy civil/facility modeling. It allows airports to integrate reality modeling, GIS, and real-time sensor data for asset lifecycle management of terminals, runways, and baggage systems.
Autodesk : Utilizing Autodesk Tandem alongside integration with Esri GIS data, Autodesk provides a digital twin solution that turns BIM (Building Information Modeling) data into a live operational hub for facilities, tracking everything from utilities to structural components.
Siemens : Siemens offers comprehensive smart infrastructure and MindSphere/Industrial IoT capabilities tailored for airports. They focus heavily on merging building automation, power distribution, HVAC, and baggage tracking into a single operational "single source of truth".
Dassault Systèmes : Through their 3DEXPERIENCE platform and virtual twin experiences, they provide large-scale systems modeling that can simulate passenger flows, facility operations, and infrastructure stress testing.
Hexagon : Hexagon provides robust geospatial, reality-capture, and sensor integration platforms (such as HxDR ) that help airports create real-time monitoring environments for safety, security, and physical asset management.
SITA : While SITA is primarily known for passenger and baggage processing, their smart airport and operations control solutions increasingly incorporate digital twin interfaces to visualize passenger flow, gate allocation, and terminal bottlenecks alongside physical infrastructure.
To help narrow down which platform fits your specific requirements, tell me:
Are you focusing more on terminal facilities and building management or airside infrastructure (runways, taxiways, gates)?
Do you already have existing BIM/CAD models or GIS data ready to integrate?
Yes. If your focus is airport infrastructure management—terminals, airfield assets, utilities, BIM models, maintenance, construction projects, and operational data—there are several platforms worth evaluating.

Esri ArcGIS
Airport GIS + facilities/asset management

IT/network infrastructure within airports
Infrastructure inventory, dependencies, planning and digital-twin management
Bentley's iTwin is particularly interesting if you want an actual infrastructure digital-twin platform rather than simply a BIM viewer or airport GIS system. It can federate engineering/BIM data, GIS, reality-capture data, IoT and enterprise information into an infrastructure twin.
There is also direct airport precedent: Bentley describes Sydney Airport using iTwin Experience as a GIS/digital-twin environment for managing terminal and infrastructure assets, including thousands of individually identified assets.
Esri ArcGIS is another strong candidate if your airport's center of gravity is GIS and facilities management. Its airport solution explicitly supports bringing BIM into the airport's geographic context and using real-time asset/operations data for utilities, maintenance, services and work orders.
What I'd look for in an airport-specific platform
Rather than choosing based on the phrase "digital twin," I'd evaluate whether it can connect these layers:
BIM/as-built: Revit, IFC, CAD and engineering models
GIS: terminal, apron, runway, taxiway, roads and underground utilities
Asset registry: equipment, doors, elevators, HVAC, electrical, baggage, lighting, etc.
CMMS/EAM: maintenance history, inspections, work orders and asset lifecycle
Reality capture: laser scans, photogrammetry and drone imagery
IoT: energy, environmental, structural and equipment sensors
Construction: projects, 4D schedules, change management and handover
Airport operational systems: gates, baggage, passenger-processing equipment and other relevant systems
3D visualization: browser-based spatial search and asset drill-down
Open integration: APIs and connectors rather than locking the airport into one data format
Security/governance: particularly important for critical infrastructure
There is academic work specifically on BIM-based digital-twin architecture for airport asset management, emphasizing integration of airport asset lifecycle information across stakeholders rather than treating the twin as simply a 3D model.
If you tell me (1) airport size, (2) whether you're an airport owner/operator or a technology provider, and (3) your primary use case—facilities/asset management, construction, operations, or all of these, I can narrow this to 3–5 concrete platforms and compare their architecture, integrations, deployment model, and likely fit.
