Common Infra Model Requirements to be published in May

The special committee of the Building Information Foundation, buildingSMART Finland (bSF), will publish the Common Infra Model Requirements on May 5, 2015. They are based on R&D conducted as part of the Infra FINBIM work package of the RYM PRE program.

The need for Common Infra Model requirements arose due to the intention of the biggest infrastructure clients to start using BIM. The client and the service providers must have a common vision of what to model and how at different stages of projects.

The Common Infra Model Requirements to be published on the InfraBIM.fi website are meant to be used as general technical reference documents of procurement and infrastructure modeling instructions. The details and practical implementation of modeling can be agreed on case by case.

Interactive and practically oriented preparation

The modeling instructions were tested and piloted in several actual projects during the preparation phase. The participants were also involved in writing the instructions.

The instructions were prepared by the parties to the Infra FINBIM work package of the RYM PRE Program until the summer of 2014 and thereafter by the Infrastructure business group of buildingSMART Finland. The following parties were involved in the preparation: VR Track Oy, Destia Oy, Finnmap Infra Oy, Lemminkäinen Infra Oy, NCC Roads Oy, Pöyry Finland Oy, Ramboll Finland Oy, Sito Oy, Tekla Oyj, Terramare Oy, YIT Infrastructure Services, Vianova Systems Finland Oy, WSP Finland Oy, A-Insinöörit Oy, Building Information Ltd, and Finnish Transport Agency.

In addition, the preparation was supported by the city members of the development team: Helsinki, Espoo, Vantaa, Turku, Tampere, Lahti and Oulu. Feedback was also given by several infrastructure operators and organizations.

Updating is a continuous process

The instructions will be updated and complemented on the basis of received feedback. The instructions are managed by the Infrastructure Business Group of buildingSMART Finland and a steering committee comprised of financiers.

International standardization of BIM and related domestic experiences will also require updating of the instructions over the next few years. Moreover, BuildingSMART Finland will update the BIM instructions for the building construction sector. That, again, will be reflected in the infrastructure instructions to ensure that the BIM instructions for the entire construction sector are in line and equally usable, for instance, in urban development projects.

In the future, Common InfraBIM Requirements will be increasingly disseminated in electronic format. For example, a Wiki type publication format has been considered.

The publication of the Common InfraBIM Requirements will take place at Espoo Dipoli on Tuesday, May 5, 2015. Use the registration form on the buildingSMART Finland website (http://buildingsmart.fi/) for electronic registration for the event.
