buildingSMART International is launching a new specialist Room for developing and deploying open digital standards specifically for the Airport environment. The Asset Management department at Amsterdam’s Schiphol Airport is taking the lead in creating this with us.
The benefits to be derived are:
Unification of digital standards to enable more efficient working from the common supply chain.
Enable Asset management decisions based on cost, risk and performance for the entire lifecycle of airport facilities to be easier to make and more robust
Make innovative design and build solutions, reducing disruption at the Airport, easier to justify and re-purposing of the facilities easier to execute.
Enable economies of scale with the supply chain and maintenance suppliers. Currently each airport group is developing its own BIM standards and there is not a uniform data exchange format to approach the market for airport facilities (eg. APBB, LEPC, airfield lights, scanners etc.).
On 12 January, a new buildingSMART chapter was launched in Switzerland. Its host organisation, Bauen Digital Schweiz (Digital Construction Switzerland) is an industry wide group formed to lead digitization of the built asset owners, their construction and facility operation supply chains as well as organisations and associations linked to construction sector.
‘Following the creation of Bauen Digital Schweiz and the launch of buildingSMART Switzerland, we are moving into the next phase of implementation and development and ask our Swiss partners to play an active part in shaping these important changes,’ said Peter Scherer
‘The new chapter has the reach and the insight to allow it to become a major player in rolling out collaborative working based on open technology,’ said Chris Groome, business manager and company secretary who manages the chapter programme.

buildingSMART has worldwide reach and operates in countries through a network of country chapters. These chapters ensure local needs are understood, promote industry change and assist with deployment of new tools and working methods.
Benelux Chapter hosts buildingSMART International Standards Summit, April 11 – April 14 2016 | Rotterdam!
We are pleased to invite buildingSMART members and their guests to attend the buildingSMART International spring summit in Rotterdam, the Netherlands.
The summit is a special opportunity to meet with world leaders in the development and delivery of open sharable data. We expect all the buildingSMART Chapters from around the world to be represented, providing an opportunity for experts to share knowledge for further enhancement of buildingSMART’s openBIM processes and standards.
There will be plenary sessions giving information about the most recent standards, processes, tools and projects, as well as working sessions dealing with key themes.
The venue is De Doelen
The schedule for the event and registration details will be available shortly.
Over 160 people from 19 different nations gathered in London Watford for the buildingSMART International Standards Conference.
Key milestones achieved during the summit include:
The inaugural meeting of the Standards Committee (SC) took place
The Standards Process, launched in Toronto, was used throughout the summit
The Standards Committee Executive (SCE) agreed to put forward, S1004 IFC alignment 1.0 and S1001 Coordination MVDs for IFC4 (Design Transfer View) and S1002 (Reference View), for endorsement as bSI Final Standard
4 Initiation requests were received to create a bSI Standard Proposal
1 Development request to approve as bSI Candidate Standard
4 Deployment request to approve as bSI Final Standard
Room Charters continued to be developed ready for final issue in June
New model view definitions will speed uptake of IFC4
A project to create a model view definition for IFC4 launched on 1 January and is now half-way through its workplan. The development of this essential tool is being done by buildingSMART’s Model Support Group, led by Thomas Liebich, and work is expected to complete in August. The tool is key to unlocking the benefits of IFC4 and allowing end-users to achieve swift, open workflows.
‘The coordination view for IFC 2×3 was broadly acknowledged to have been very successful,’ says Thomas. ‘But now that we are moving on to a model view definition for IFC4, we have the opportunity to learn from past experiences.’
Why is the model coordination view needed? A model view definition (MVD) is a subset of the IFC standard. ‘Software solutions supporting IFC are always based on an MVD – a subset that meets the needs of one or more particular use cases,’ Thomas explains. ‘The coordination view is probably the most important tool for implementing IFC in commercial software products.’The main use case of the coordination view is to support the exchange of information between the separate models of the structural, architectural and building services disciplines. The architectural design mustn’t obstruct the structural elements and the building services mustn’t block either the structure or the architecture: for this reason, the clash detection support of IFC has long been valued. It is regularly cited as one of the greatest benefits of IFC. A number of other use cases are also covered in the MVD, including consistency control, building code checking, the coordination of voids and tighter integration of architectural, mechanical and structural design and detailing.
Swift and easier to use: the new coordination view. Coordination planning and clash detection represent one of the most important workflows today. The IFC 2×3 coordination view was widely implemented by software vendors who submitted their products for bS certification – and overall it commanded the confidence of the market. But end-users were in practice often frustrated because it did not distinguish between different workflows.
The many demands made of it meant that heavy computation was necessary and this in turn led to long loading times for import and export. For certain activities, the complex geometry inherent in the view, and the way it operated, made it cumbersome. It was providing a sledgehammer to crack a nut, or – as Thomas puts it – ‘it was shooting beyond the mark’. To resolve this problem, the Model Support Group decided to split the coordination view into two sub-views: the IFC4 reference view and the IFC design transfer or handover view. The goal of the reference view is to enable the swift, accurate exchange of information between disciplines for reference. As the definition of the project explains, the view must allow 100% correct explicit geometry and 100% correct attributes, properties and spatial structures, with rapid export and import times and no need for rework. The goal of the design transfer view – this is a working title – is to allow the BIM model to be handed over to the next stage of editing, which is likely to be a once-and-for-all adoption, with a modicum of rework and longer import/export times acceptable. Responsibility for the transferred model is likely to be taken over by the receiver. ‘While providing a generic solution, we are able to meet the separate needs of reference and transfer,’ says Thomas.
What next? The project, stage one of which is funded by the Norwegian National Office of Building Technology and Administration, is expected to complete in two phases in July and September. Software companies can then start to implement the view in their software products, with buildingSMART certification to IFC4 due to begin some time in 2015. ‘Results of our work will provide immediate benefits,’ concludes Thomas. ‘End users will be able to use open solutions for collaborative workflows, clients can require project information to be delivered in an open format and software vendors will be able give their customers design tools that work fast and efficiently.’
buildingSMART has released the version 1.0 of mvdXML – the new schema and method to publish official subsets of IFC to satisfy well defined data exchange requirements.
Model View Definitions (MSG) have been the method to publish the IFC implementation requirements to satisfy data exchange requirements since a long time. The most well known buildingSMART MVD is the IFC2x3 Coordination View 2.0, currently open for certification. Read more on the IFC Dev Blog here
