LIBAL® Successes - Project requirements are loaded from the buildingSMART Data Dictionary

LIBAL® brings BIM usable into operation. Model based project requirements are loaded from the buildingSMART Data Dictionary and PDT's are provided with attributes which are to be developed by CRB and tested on the LIBAL system.

Current challenge

Manual entry of supplier data is time-consuming and error-prone.

BIM models look very good at first sight and usually have an information level of LOI350. For a sufficient BIM4FM with a LOI500, a large amount of information has to be captured during execution, which takes a lot of time to capture and control.

To generate information, individual objects are loaded from libraries into BIM projects or created in CAD. These objects must be supplemented by values that are transferred from Excel lists according to customer requirements. The planners implement the customer requirements accordingly by opening properties in their CAD systems in the form of property sets and their attributes.

To enter the data in the model, the supplier sends a data sheet by e-mail to the planner, who adds the information to the CAD system with Copy/Paste. This procedure is carried out manually and requires a very high degree of care on the part of the planner to record the data at the correct location.

For the correct grouping, the designation of the attribute, as well as the attribute type and its unit, each attribute must be coordinated with the building owners, so that the appropriate values can be transferred correctly into the target systems of the management.


Standardized Product Data Sheets (PDS) according to CRB templates, which are retrieved by buildingSMART Data Dictionary (bSDD) for the information request, automate the process for the provision of the information request by the building owners, the data transfer by the supplier, as well as the qualitative examination of the specialist planners.

On LIBAL the models are imported and the corresponding objects are the PDT/CRB specifications from the BsDD supplemented. The supplier is integrated directly into the model, in his scope of supply, where he can transmit the information. Testing and coordination takes place online at the object.

During execution, the suppliers are integrated into LIBAL in order to write the required project data into the PDT templates, so that the client receives a complete electronic product data sheet, which is transferred to management. Quality assurance is ensured with the model-based workflow management by checking the data and documents after receipt by the specialist planners.


Customer benefit

Data generates added value for the client if it can be used in subsequent management processes.

With LIBAL, building owners specify the requirements for data and documents that are required for the management of a property based on models, so that they receive them checked over the entire life cycle of planning, construction and operation. The clients save time and money in obtaining the relevant information they need for the optimal operation of their property.

The quality of the data structure is ensured by specifying standardized designations, types of attributes and their groupings within the product data template.

In model-based information management, the quality of the recorded values is increased by the supplier by ensuring the traceability of the data check by the specialist planner.


About buildingSMART Data Dictionary

The buildingSMART Data Dictionary (bSDD) is a library of object concepts and their attributes based on the IFD standard (ISO 12006-3). It is used to identify objects in the built environment and their specific properties language-independently, so that "door" in Iceland means the same as in India.

The bSDD is open and international so that architects, consultants, owners and operators on the one hand and product manufacturers and suppliers on the other can exchange product information from all over the world. When everyone speaks the same language, the construction process becomes more efficient.


About CRB Central Office for Construction Rationalization

The Swiss Centre for Building Rationalisation CRB is the competence centre for standards in the construction industry.

Together with numerous professional associations, CRB develops work equipment for the entire life cycle of a building - from planning through implementation to management. With their uniform systematics and language rules, they enable clear, unambiguous performance descriptions as well as efficient and transparent cost management.
