Property portfolio management

Several buildings, one way of knowing them: a model for each building, at the level needed, and a shared data structure for spaces, areas, building services, documents and deadlines.

At a glance

B1P Group's property portfolio management brings a portfolio of buildings into BIM: a model for each building, at the level of detail needed, and a shared data structure that makes spaces, areas, building services, documents and deadlines comparable. It serves owners, funds, public bodies and operators who must decide on several buildings with consistent, up-to-date data, and it connects to the property and facility management systems they already use.

Definition

What is a digital property portfolio?

It is the set of models and data of all the buildings of an owner or an operator, organised with the same rules: the same classification of spaces and components, the same codes, the same documents linked to the same objects. For each building the level of model needed is chosen, from a record with areas and documents to the complete operation model.

The difference from the operation of a single asset lies in comparison: a portfolio is managed with consistent indicators, and the data only count if they are collected in the same way for every building.

Deliverables: A model per building at the agreed level, shared data structure and coding rules, register of documents and deadlines linked to the models, comparison dashboard, export to property and facility management systems, update procedures
Standards: ISO 19650-3 for the operational phase, UNI 11337, the information requirements of the owner or operator
Tools: Revit for the models, IFC and COBie for exchange, integration with the client's management platforms through their formats

Property portfolio management

Where do you start with many buildings?

With a census: which buildings, which documents exist for each, which decisions the portfolio must support. On this basis the priorities and the level of model for each building are set, because not every building needs the same detail.

For buildings without a model, the starting point is the existing documents with existing conditions modelling, or the survey carried out by the appointed surveyor with BIM modelling from survey data.

Property portfolio management

Why is a shared data structure needed?

Because without shared rules each building speaks a different language and comparisons do not hold. The data structure sets how spaces and components are classified, how areas are measured, which parameters are mandatory and how documents are coded; it applies to the models we deliver and to those that will come from others, through the owner's information requirements.

With consistent data, areas by use, occupancy, maintenance costs and consumption can be compared, building by building.

Property portfolio management

How are documents and deadlines kept under control?

By linking them to the objects of the model and to a single register: certifications, scheduled maintenance, periodic inspections, contracts. Every deadline refers to a building, a space or a component, and whoever manages it sees it in its context instead of in a separate list.

The next step, for the buildings that justify it, is the connection to operational data with the digital twin.

Levels

Which level for each building?

The levels of model in a portfolio, with what they include and the decisions they support.

Level	What it includes	For which decisions
Building record	General data, areas, documents and deadlines	Overview of the portfolio, priorities, obligations
Simplified model	Volumes, floors, spaces and uses	Use of space, value enhancement, due diligence
Asset information model	Maintainable components and building services with their data	Maintenance, service contracts, interventions

Frequently asked questions

Frequently asked questions on property portfolio management

Is a complete BIM model needed for every building?

No. The level is chosen building by building based on the decisions to be made: for many, a record with areas and documents is enough; the complete operation model is needed where there is maintenance to manage.

Can we keep using our own management software?

Yes. The portfolio connects to the client's property and facility management systems using their formats and open formats such as IFC and COBie: there is no need to change platform.

How many buildings is it worth starting with?

Even a few, if they are the ones on which decisions must be made. The shared rules are set at the start, so buildings added later join the portfolio without redoing the work.

Who keeps the data up to date over time?

The operator, with written procedures that are part of the delivery. B1P Group can support the updates and train the people who carry them out.

Do you have several buildings to know and manage with the same data?

Tell us how many there are, which documents you have and what you need to decide: we will propose the levels of model and the shared data structure.
