Combining ArcGIS Indoors with Trimble Unity Maintain can be leveraged to manage vertical assets in facilities as well as the facilities themselves. This creates a synergy that is unrivalled by any other asset management solution.

ArcGIS Indoors & Trimble Unity Maintain: powerful facility management.

Today, I’d like to talk about ArcGIS Indoors and how it can be leveraged to manage vertical assets in facilities as well as the facilities themselves. When integrating ArcGIS Indoors with Trimble Unity Maintain, you create a synergy that is unrivalled by any other asset management solution. Let’s take a deeper dive into both systems and how they work together to change operations for good.

ArcGIS Indoors: a modern indoor GIS platform

ArcGIS Indoors transforms CAD/BIM plans into interactive, floor-aware maps which can support 2D/3D visualization and room-level detail. By integrating data on room usage, assets, occupancy and safety features, you can enhance your ability to manage a facility on a more holistic basis, as well as sharing information with the users of that space.

Furthermore, the platform supports space reservations (hoteling), wayfinding and cross-building/cross-floor navigation. This can modernize the workplace and campus experience for both workers and users alike, while factoring accessibility or large loads.

The latest updates have introduced multi-facility floor filtering which allows you to look at different floor layouts in different buildings from one interface. Recent improvements were applied to the editing tools for the desktop pros and a refreshed Indoors Mobile application with turn-by-turn navigation, 360-degree photo support, and even organizational branding.

Ultimately, ArcGIS Indoors serves as a flexible framework for custom workflows which enable organizations to extend their data model and build tailored apps for space planning, operations and smart-building initiatives.

Facility & asset management capabilities in ArcGIS Indoors

The problem that most organizations are facing is that their data is non-interoperable. That is to say that it exists in multiple formats that don’t (or can’t) speak to each other. For example, data may exist on paper, Excel spreadsheets or even in old legacy database systems such MS Access or other deprecated systems.

The US National Institute of Standards and Technology (NIST) has estimated that the cost of non-interoperable data can be as high as $0.32 per square foot in a facility. When tallied, this equates to $22 Billion CAD annually in annual efficiency losses. This means tens of thousands of dollars over multiple average sized facilities, and much more for larger scale facilities.

ArcGIS Indoors solves this problem by allowing facility management teams to track and manage indoor assets, visualize maintenance needs and support preventative maintenance through real-time data integration.

Centralized data management and visualization create a common operating picture for all staff and stakeholders. It is taking Geographical Information Systems (GIS) to an indoor environment where the lifecycle of CAD and BIM drawings are extended from just being design documents to fully living operational and maintenance datasets. After initial CAD/BIM drawings are completed, they stay that way. GIS evolves and can provide an additional dimension – time.

Trimble Unity Maintain: a GIS-centric asset management solution

Trimble Unity Maintain, a cloud-based, GIS-centric enterprise asset management platform, enables end-to-end lifecycle visibility while also addressing challenges such as data duplication, inefficient workflows, regulatory compliance and aging infrastructure by centralizing asset information and all maintenance activities.

Trimble Unity Field supports work order management, asset inspections, geospatial asset inventory, and field-to-office workflows. This approach democratizes your facility data, so it is in the hands of the people who interact with your assets daily. This reduces the need for updates from the GIS team as field workers can automatically update asset attributes by simply completing work activities from the field in the mobile app.

Unity Maintain also improves decision making with predictive analytics, asset risk assessment, work performance and tracking and strategic work planning.

The most powerful feature of Trimble Unity Maintain is its seamless integration with Esri ArcGIS, which means you get all the powerful mapping, location intelligence and spatial analysis to support infrastructure planning and maintenance backed with a single source of truth for the asset register, with no custom or proprietary methods requiring upkeep.

The synergy: ArcGIS Indoors + Trimble Unity Maintain

While ArcGIS Indoors provides the data and room-level spatial context, Unity Maintain manages the operations and maintenance lifecycle of the assets. One provides the data and the other tells you what you do with that data. Together: they provide a unified environment for both indoor and outdoor infrastructure operations from room to floor, to building and across the whole site or campus.

Trimble’s solutions natively integrate with ArcGIS workflows. This enables high-accuracy field data capture, real-time asset updates and seamless sharing across platforms. ArcGIS Indoor workflows are now more deeply supported in the Unity Field mobile application, including Facility ID and Level ID fields, floor-aware maps and auto-assignment of floor levels during work activity creation.

Together, the combined solutions allow organizations to:

Link indoor maps directly to asset records and work activities
Dispatch technicians with precise floor-level navigation & wayfinding
Track asset history and performance in a spatial context
Modernize operations through digital workflows while reducing data silos

Bringing in ArcGIS Indoors data is as simple as publishing floor-aware map services and consuming them directly in Unity Maintain. The Respond plugin has native built-in tools to interpret and display the floor-aware maps, and even 3D web scenes from ArcGIS.

Why this combination matters for public works managers & facilities owners

Organizations need a single operational picture for both their indoor and outdoor site assets to improve efficiency, safety and cost control. The combination of ArcGIS Indoors and Trimble Unity Maintain supports proactive maintenance, reduces downtime and strengthens community trust through transparent service delivery.

Both systems align with the industry shift toward smart buildings, digital twins and integrated asset lifecycle management.

Are your operations future-ready? They can be…today.
