The BIM layer
Model import, three-dimensional visualization, selection, filtering, properties, sections and measurements support the spatial identification of elements.
Mobius BIM
Building and construction asset management
MOBIUS BIM
The building model, connected to inventory, maintenance and decision-making.
An extension of MOBIUS UEAM for operating buildings across their entire lifecycle. BIM — Building Information Modeling; FM — management of buildings and support services.
InventoryAn identity for each asset.
Spatial contextA coherent view of spaces and systems.
OperationA common history for works, documents, resources and costs.
01 · Positioning · Continuity with MOBIUS UEAM
A building is not just a model. It is a set of assets in operation.
MOBIUS BIM extends MOBIUS UEAM — Unified Electronic Asset Management — with an information and visual layer dedicated to buildings and constructions. The geometric model becomes the context for the technical inventory, documents, maintenance, interventions and costs.

MOBIUS BIM
The asset in the real building
Operation with coherent information
Operation with coherent information
The same operational core, complemented by the information representation of the construction.
BIM: information, not just geometry
BIM (Building Information Modeling) means the information modeling of constructions: a digital representation that associates properties, relationships and documents with geometry. In operation, its value lies in the verifiable link between the represented element and the real asset.
FM: managing the building in use
FM (Facility Management) refers to the management of buildings, spaces and support services. Applying BIM in this phase brings location, technical condition, responsibilities and works together in a common context.
Continuity with UEAM
The asset register, preventive plans, corrective works, dispatch, mobility and cost analysis remain the operational core in MOBIUS UEAM. The BIM extension adds spatial navigation, model properties and element–asset association.
Solution presentation: it describes the proposed extension of UEAM; the availability of BIM functions and integrations is established in the analysis and implementation stage.

The MOBIUS UEAM Core
Asset identity, classifications, plans, works, teams, documents, resources, costs and history are managed in the common operational model.
Controlled integration
MOBIUS BIM integrates open source libraries from the That Open Platform ecosystem, in particular That Open Engine and Fragments, for the BIM functions; asset registers and operating processes are provided by MOBIUS UEAM.
Workflows, rights and interfaces with the organization's systems are configured in the project; operational functions are not provided automatically by the visualization engine.
05 · Exploring the model & BIM + UEAM capabilities
See where the asset is. Understand which system it belongs to.
The BIM visualization proposed for the extension supports exploring the building directly in a web interface, alongside the operational register.
01 · IFC
Import and verification
IFC (Industry Foundation Classes) as an open exchange format: checking units, coordinates, levels, spaces, categories and duplicate objects.
02 · VISUALIZATION
Visualization and selection
Navigating the model directly in the web interface, selecting an element, highlighting it, consulting its properties and filtering by level, category or system.
03 · SECTIONS
Sections and isolation
Section planes and isolation of elements that make hidden installations, technical spaces and the relationships between components understandable, with saved views.
04 · MEASUREMENTS
Measurements and properties
Geometric tools for indicative measurements (distances and areas) within the limits of the available model; properties read directly from the model data.
05 · ASSET RECORD
A single asset record
The common point of operation, accessible from the inventory, by selecting the BIM element or by physical identification (QR/NFC) of the equipment.
06 · MAINTENANCE
Plans and works
Preventive plans and corrective works with operations, frequency, owner, competences, parts and documents associated with each asset class.
07 · DISPATCH
Interventions and BCF
From a located report to a traceable intervention, with the option of associating findings in BCF (BIM Collaboration Format).
08 · CONTROL
Portfolio, GIS and KPIs
Moving from the map (GIS) into the building (BIM), integration with BMS/meter systems and operational analysis by condition, risk, resources and costs.
Context, not a replacement for design: the extension is intended for operation. Automatic checking of all clashes, structural calculation or energy simulation are not assumed. Measurements from the model do not replace surveys and field checks.
03 · The construction inventory
From portfolio to room, system and equipment.
The inventory covers the building as an asset, its construction components and the equipment used in it. Spatial organization and membership of a technical system are two distinct but complementary relationships.

Portfolio
Properties and sites
02 →

Construction and annexes

04 →
Asset
Element, installation, equipment
05 ↔
Technical system
Relationships between assets in several spaces
Spatial structure
Portfolio → site → building → level → room or zone. An installation can span several levels; its location should not be confused with belonging to a single space.
Construction elements
Structure, roof, facades, windows and doors, partitions, floors and external works. Type, materials, condition, documents and maintenance works are tracked.
Installations and equipment
Heating, ventilation, air conditioning, electricity, water and sewerage, elevators, access, furniture and specific equipment. Safety systems are inventoried without replacing their dedicated functions.
Not every geometric object has to become a maintenance asset. The level of detail is chosen according to operational usefulness, criticality and the cost of keeping data up to date.
04 · Data preparation & 06 · The asset record
A usable model starts with data that can be verified. The element in the model and the object in the field share the same story.
Importing a model is not the same as handing over a complete inventory. Information for operation is checked, completed and correlated with reality in the field.
- IFC import and verification: units, coordinates, levels, spaces, categories, properties and duplicate objects checked before association.
- Stable identity: the BIM element is linked to the UEAM asset code through an explicit correspondence (IFC identifier + source model + version kept on re-export).
- Minimum set for operation: asset code, name, class, location, system, condition, criticality, owner, manufacturer and serial number, documents, warranty and maintenance plan.
- Buildings without a BIM model: the UEAM inventory can be built before the model from plans, documents and surveys; the BIM representation is added in stages for areas with operational value.
- Reconciliation on revision: added, removed or modified elements are reconciled before publication, with human verification and history kept.

History & costsPlans, work orders, parts, labor, services and confirmations. Replacing a piece of equipment keeps traceability between the retired asset and the new one.
Explicit link: asset code ↔ element identifier + source model + version. Missing properties are marked as missing, not filled in by assumption.
07 · Maintenance & 08 · Dispatch
Maintenance is a controlled process, not a color in the model. From a located report, a traceable intervention.
The model provides location and technical context. MOBIUS UEAM handles the planning, execution, resources and history of interventions, keeping accountability for each stage.
Preventive plan
Operations, frequency, owner, competences, parts and documents associated with each asset class. Deadlines derive from instructions, procedures and applicable obligations, not from BIM geometry.
Corrective work
A finding is assessed by criticality and impact. The work receives a priority, deadline and team. The model view helps with location and preparing access, without guaranteeing diagnosis of the fault.
Execution and confirmation
The team records operations, parts, consumption, duration, photos and the result. Technical confirmation and administrative closure are carried out according to the configured responsibilities.
Examples of classes
Pumps and ventilation units: functional checks; roofs and facades: condition inspections; boards and lighting: works according to procedures; furniture: inventory, repair and replacement.
01

04
Execution
Operations, parts, consumption, duration, result and cost.
05
Closure
Technical/administrative confirmation and history update.
BCF (BIM Collaboration Format) technical collaboration: a BCF finding can be linked to a report or work; importing it does not automatically create an approved work order. Highlighting assets with overdue works in the model is configured in the project based on validated operational data.
09 · Field and portfolio & 11 · Systems and consumption
From the map into the building. From the building to the asset. Measured data makes sense when it is linked to spaces and assets.
GIS (geographic information system) provides the external context of the portfolio; BIM provides the internal and technical context of each construction, and connecting to existing systems can add statuses, alarms and consumption.
Building portfolio and GIS context
The map brings together sites, buildings, external works and teams. The inventory makes it possible to compare condition, works and costs between properties without artificially standardizing their particularities.
Physical identification (QR / NFC) and the UEAM mobile app
The Android mobile component uses QR and NFC, providing access to the asset record, scanning, photos, findings and work confirmation. BIM visualization on mobile devices is sized and verified separately, according to model size and device.
Context for installations (BMS) and consumption analysis
The BMS can provide operating data through agreed interfaces, and meters and sensors are associated with assets, zones and technical systems. Electricity, heat or water consumption is tracked according to the available measurement points (geometry does not create real sub-metering).
From signal to work order, and functional limits
A validated alarm can trigger a report after checking the meaning, source and recurrence of events. The solution does not replace certified protection, automation or safety systems, and visualizing data does not imply controlling installations.
Location and measurement limits: navigating the model does not automatically provide precise indoor positioning. No percentage savings or native energy simulations are promised; results are established from real measurements and documented interventions.
10 · The lifecycle
Information has to survive the handover of the building.
MOBIUS BIM links design and construction information to day-to-day operation and to decisions on renovating, replacing or retiring assets.
01
Handover
As-built data and model · Verified inventory, documents and warranties.
02
Operation
Use and technical condition · Field checks and updates.
03
Maintenance
Plans and works · Resources, parts, costs and history.
04
Renovation
Assessment and investment options · Controlled model revision.
05
Retirement
Replacement or scrapping · Archive and continuity of operational memory.
Handover for operation
The model describing the as-built situation, the equipment list, documents, warranties, locations and responsibilities are checked. Information acceptance is not to be confused with the technical or legal acceptance of the construction.
Controlled updating
Changes of location, replacements and modifications to installations produce operational updates and, where necessary, model revisions. Publication takes place after the element–asset links are reconciled.
Renovation and decisions
The history of faults, costs, risk and downtime supports the prioritization of investments. Versions and documents keep the previous context; a new model must not erase the operational memory.
The building's technical book and mandatory documents continue to be managed according to the applicable requirements. The BIM model can organize and contextualize them, but does not replace them.
12 · Usage scenarios
The same asset logic, adapted to each construction.
The common model is suitable for individual buildings, campuses and distributed portfolios. Configuration takes into account use, criticality and responsibilities.
Administrative building
Installations, offices, technical spaces, furniture and external works. An air-conditioning fault is associated with the unit, the spaces served and the remedial work, if the relationships are documented.
School or campus
Teaching buildings, gym and sports grounds, furniture, teaching equipment, perimeter lighting and installations. Interventions are scheduled in line with the use of spaces and access rules.
Hospital or building with critical functions
Maintenance of installations is coordinated with the affected zones and services. Planning of access and shutdowns is approved by those responsible; the model does not on its own determine the continuity of services.
Related constructions and facilities
Car parks, warehouses, annexes, site networks and construction components of other properties. The BIM scope and model quality are checked for each type of construction; coverage of all types is not assumed.
The examples describe configuration scenarios, not projects already implemented. The specialized functions and integrations needed are confirmed for each client.
13 · Operational control
Decisions are based on the history of assets, not just on the 3D image.
Reports connect technical condition, works, costs and data quality. Filtering by building, level, system or asset class allows analysis at the appropriate scale.
Condition and risk
Assets with faults, repeated findings, critical components and zones with operational impact. Criticality criteria and risk assessment are approved by the organization.
Execution and resources
Preventive deadlines met, overdue works, reaction time, time to closure, tasks per team, parts and services used.
Cost per asset and property
Documented costs per asset, system, building and period. Budgets and investments are compared only using agreed data and accounting rules; the model does not automatically calculate asset value.
Quality of the BIM–UEAM inventory
The degree of completion of mandatory fields, assets linked to the model, unvalidated links, missing documents and unreconciled changes. The indicators specify the numerator, base and period.
A control dashboard can highlight the areas that need attention. Colors in the model reflect statuses calculated from operational data; they do not represent a technical expert assessment of the construction.
Concrete operational value · Comparison
What changes when the building model is linked to the UEAM operational register.
The difference between a 3D model kept in isolation in the design archive and a living record of the building, connected to maintenance, dispatch and decision-making.

Unclear reports, searches through old drawings and repeated site visits to identify which unit serves the affected area or where hidden installations run.
Unclear reports, searches through old drawings and repeated site visits to identify which unit serves the affected area or where hidden installations run.
Spatial and system context
Sections, isolation and filtering by level, category or system directly in the web interface; the dispatcher and the team see the location, relationships and documentation before the intervention.

3. Replacing equipment in the technical room
E.g. circulation pump, fan, electrical board
Loss of technical memory
The history of the replaced equipment stays isolated in old spreadsheets, and when the BIM model is re-exported the IFC identifiers can change, breaking the link with the work records.

Stable identity and traceability
The UEAM operational code keeps traceability between the retired asset and the new one, and controlled reconciliation on model revision keeps the complete history of parts and costs.

A controlled process in UEAM
Preventive plans start from applicable procedures and obligations; the team physically identifies the asset (QR/NFC) in the UEAM Android app and records operations, consumption and photos.

14 · Implementation
A well-chosen pilot before extending to the portfolio.
Implementation starts with the operational objectives and verification of data sources. The most detailed model is not automatically the most useful for maintenance.
Analysis and data conventions
The priority processes, asset classes, roles and sources are chosen. The mandatory fields, level of detail, codes, documents and the owner of each update are established.
Inventory and correlation
Data is taken over, the model is verified and the element–asset correspondence is built. The list of exceptions and assets without a model are handled explicitly, through field checks.
Operational pilot
A representative building or system goes through the complete flow: selection in the model, access to the record, report, assignment, execution, cost, closure and reading the result in the history.
Acceptance and extension
Import, performance on real devices, rights, workflows, documents and model revision are tested. Extension follows after training and acceptance of the pilot results.
Deliverables: a reconciled inventory, data conventions, validated models, configured workflows, operating documentation, training and acceptance criteria. The schedule is set after assessing the real data.

15 · Milestones and outcome
A living record of the building, connected to day-to-day work.
MOBIUS BIM applies the discipline of asset management to construction information: clear identity, understandable location, explicit responsibilities and verifiable history.
Abbreviations used in the solution
BIM— Building Information Modeling
FM— management of buildings and support services
UEAM— Unified Electronic Asset Management
IFC— open exchange format for models
BCF— exchange of issues and views associated with the model
GIS— geographic information system
QR— scannable two-dimensional code
NFC— near-field identification
BMS— building management system
Limits of use and validation through a pilot
The model must be maintained and checked against the field. The solution does not replace design, technical expertise, authorized inspections, mandatory documents or safety systems. New functions are validated through a pilot before operational use.
What is confirmed during the analysis and implementation of the solution?
The availability of BIM functions, integrations, accepted models, performance on real devices, rights and workflows. The solution presentation describes the proposed extension of UEAM, validated through a pilot before operational use.
How are IFC models and buildings without a BIM model managed?
IFC is the open exchange format. The asset code, element identifier, source and version are kept, and changes are reconciled with human verification. The UEAM inventory can be built before the model from plans, documents and surveys; automatic conversion of drawings into complete models is not assumed.
What is the technical basis of the BIM layer?
MOBIUS BIM integrates open source libraries from the That Open Platform ecosystem, in particular That Open Engine and Fragments, for the BIM functions. The MOBIUS UEAM Core provides the asset register and operating processes; the visualization engine does not automatically provide operational workflows.
