BIR aims for the successful implementation of BIM in Dutch construction. The members of the Council are the ambassadors of the organization, but BIR also produces various concrete products. BIR’s goals and activities are described in a programme plan that is updated annually.

Knowledge Leaflets 

To make BIM knowledge more widely available, BIR has produced several knowledge leaflets. These leaflets make it easier for you to find the information you need to use BIM in practice. The leaflets provide practical information on various matters related to the implementation of BIM, such as roles and competences, legal aspects and the BIM transition in organizations.

National Models for BIM Protocols and BIM Execution Plans

Effective work agreements are indispensable to be able to successfully apply BIM in construction projects. These agreements are often set down in BIM Protocols or BIM Execution Plans. There is a wide range of such protocols and implementation plans in circulation. However, the terms used are open to interpretation and it is unclear which information is superfluous and which is missing. To remove these ambiguities, the BIR BIM Protocol working group has developed two models: the “National BIM Protocol Model’ and the ‘National BIM Execution Plan Model’. The BIM Protocol Model can be used to establish project-specific contract provisions for BIM projects. The BIM Execution Plan Model is a template that project teams can use to establish BIM work agreements. The models also introduce a uniform conceptual framework that harmonizes with the developments in the countries around us and prepares for future European BIM standardization.

The national models can be downloaded from the BIM Loket website.

CB-NL Semantic Standard

The Dutch Concepts Library for the built environment (CB-NL) is a digital semantic library, a collection of language definitions for objects and spaces used to harmonize various existing standards, norms and object/product libraries. CB-NL has been developing a shared language to facilitate the exchange of construction information using open standards since 2013. This translation engine will play an increasingly significant role in translating, searching, comparing, enriching, simplifying and, most importantly, linking the information that is required to make construction projects more successful and more affordable. The further development of CB-NL is managed by BIM Loket and coordinated by the CB-NL Steering Committee:

COINS exchange standard

COINS is an open BIM standard for the exchange of digital information between various IT platforms and environments used in construction projects. The standard ensures that various types of information can be combined in a single database, such as functions, requirement and object trees, GIS data, 2D drawings, 3D models, IFC models and object-type libraries. The COINS standard was introduced in July 2010 and was followed by COINS 2.0 in 2016. Version 2.0 supports more open-source software with an API (the COINS Navigator). The COINS standard is being developed under the responsibility of BIR and is coordinated by BIM Loket:

SE model

BIR and the four-party committee (4P) launched a project in 2015 to identify the information requirements for Systems Engineering (SE). This is necessary to further integrate SE in BIM. 4P is known for its SE Guideline and consists of Prorail, Rijkswaterstaat, NLengineers, Bouwend Nederland, Vereniging van Waterbouwers and UNETO-VNI. It provides a platform for an SE dialogue between clients and contractors in the civil engineering industry. SE is a fast-growing field and the industry is working hard to translate the methodology into practical applications. The SE Guideline provides a joint framework with uniform concepts and processes. See for more information.

The SE-BIM working group was commissioned by BIR and 4P to develop an exchange model for SE (the SE Model). This is a major step towards the standardization and electronic exchange of SE data (including specifications and the related validations and verifications) between stakeholders in construction projects. The SE Model is primarily intended to be used in combination with the COINS 2.0 exchange standard, but it can also be used without COINS. The SE exchange standard is available online.


The Building Information Council cooperates with Dutch Universities of Applied Sciences to improve the integration of BIM in education and encourages them to share experiences. The BIR Programme Office functions as a sounding board to this end.

BIM Loket

BIR was the driving force behind the creation of BIM Loket. BIM Loket is a partnership between various knowledge organizations that manage open BIM standards. All BIM users (clients, designers, contractors, suppliers) can approach BIM Loket to ask for practical advice and support in the use of open BIM standards. BIM Loket manages a coherent collection of open BIM standards such as VISI, NLCS and COINS. These standards contribute to an open BIM process with more efficient communication, less loss of time and higher quality construction projects at lower costs. BIM Loket encourages the use of BIM in the Dutch construction industry and helps to make the transition to BIM as seamless as possible, both at home and abroad.
