What are the BIM standards in the EU?
Driven by the fast shifts towards digitalisation in the construction industry the EU has set up a programme to develop and define standards for BIM (Building Information Modelling) across all European countries.
The technical committee 442 was set up to take charge of the standardisation work regarding all information in the built environment.
As of October 2016 the buildingSMART International standards put forward by CEN/TC 442: IFD (ISO 12006-3:2007), IFC (ISO 16739:2013) and IDM (ISO 29481-2:2012) are officially adopted as EN standards. Find out more here.
What is the scope of CEN 442?
Standardization in the field of structured semantic life-cycle information for the built environment through specifying methodologies to define, describe, exchange and monitor, record and securely handle asset data, semantics and processes with links to geospatial and other external data.
Establishing a common technical language for all European actors
As members of the Work Group 4, Cobuilder have devoted great deal of our R&D efforts in contributing to the following initiatives:
Establish a common technical language for all European actors eg.
• Setting a common Data Dictionary framework
• Harmonization of product properties and classification tables

Next stop: The process
With the digital revolution in the construction industry, and especially with the introduction of BIM, it is of the highest important that the information is reliable and machine readable. A good process for collaboration between participants in construction projects and in asset management is pivotal to the efficient delivery and operation of facilities.
PPBIM (XP P07-150) is a French standard, published in December 2014, which provides a methodology to define and manage construction product properties for digital use. The principle is to connect every property to attributes such as the definition coming from a reference standard within a particular local context.
- The process creates a rigorous system of validation of all digital contents and defines how properties and property groups shall be established by users and experts in a dictionary, as well as how this content shall be mapped to other dictionaries.
- The objective is to allow quality information exchange between industry players for multiple uses such as the digital model, also for international trade and the needs for maintenance.
This standard is now accepted within CEN/TC 442 WG4 to be a New Work Item Proposal (NWIP). There are clear relations between the PPBIM process and the UK LEXiCON, with both initiatives describing the need for a process that enables creation, verification and maintenance of dictionary content by experts. In the last CEN/TC 442 WG4 meeting, UK officially supported the PPBIM process/standard through a common joint presentation for the members of WG4.
So that means that the view on having common European datasets for all industry players, in order to help them distribute their digital data towards all the different countries in Europe, is something that is now becoming real via the BIM standards and specifically the work that is done in CEN 442.
