IFC4 Design Transfer & Reference Views are now bSI Final Standards

buildingSMART International has generated two more open sharable standards through its Standards Program. The development of these standards has followed a rigorous process and been endorsed by the International Standards Committee.

The purpose of the IFC4 Design Transfer View is to provide building information with support for editing of interconnected elements.

IFC4 Design Transfer View

Such applications enable inserting, deleting, moving, and modifying physical building elements and spaces. An example of a target scenario is an architect providing building design information to an engineer for a particular discipline, where geometric modifications may need to be made.

The main purpose of the IFC4 Reference View is to define a standardized subset of the IFC4 schema, a Model View Definition MVD, that is particularly suitable for all BIM work flows that are based on reference models where the exchange is mainly one-directional.

Open BIM | Trimble and Nemetschek Group Partner to Expand Adoption of Building Information Modeling Across Building Design, Construction and Operation

Companies Collaborate to Promote Openness and Interoperability Across their Solution Portfolios

SUNNYVALE, Calif., and MUNICH, May 4, 2015—Trimble (NASDAQ: TRMB) and the Nemetschek Group (XETRA: NEM), leaders in digital solutions for the Architecture, Engineering and Construction (AEC) markets, announced today that they have formed a strategic alliance to expand the deployment of Building Information Modeling (BIM) across the entire Design-Build-Operate (DBO) lifecycle of buildings. The alliance will emphasize collaborative approaches to design modeling and 5D construction management through data integration between a variety of the companies’ products.

The announcement was made today at the Lake Constance 5D-Conference 2015 held this week in Constance, Germany.

Trimble and Nemetschek will share their extensive global market and technology expertise and collaborate on initiatives to drive a paradigm change in the development and adoption of technologies for the AEC industry and building owners.

The companies intend to:

  • Transparently share data formats to support new solutions and promote workflow interoperability between selected products across the DBO lifecycle;
  • Tighten the connection of Virtual Design & Construction (VDC) solutions to real data from the field and real objects in the physical world;
  • Support interoperability and the longevity of project data for the entire project lifecycle;
  • Maintain their respective deep commitments to open standards and workflows for the benefit of the entire industry—rather than for any individual vendor.

Open, Connected and Interoperable via Trimble Connect

Trimble and Nemetschek plan to leverage the Trimble® Connect collaboration platform to integrate workflows and create close interoperability between selected Trimble solutions—including SketchUp, Tekla Structures, Vico Office, Trimble Prolog®, Trimble Field Link and MEPdesigner for SketchUp—and solutions in the Nemetschek portfolio, such as Allplan, ArchiCAD, DDS, Scia Engineer, Vectorworks and Nevaris.

Both companies are committed to open standards and workflows—a rapidly emerging approach to the collaborative design, construction and operation of buildings. With Nemetschek solutions supporting the Trimble Connect platform—a cloud-based collaboration environment that features an open environment for BIM-based AEC workflows—Trimble and Nemetschek are coordinating their efforts to offer best-of-breed solutions for customers.

“Across the DBO spectrum, customers want the freedom to choose the best tools for the job and the security of knowing those tools will work together. But too often they find that the data they need is not interoperable across their different software workflows,” said Bryn Fosburgh, vice president responsible for Trimble’s Construction Technology Divisions. “Our companies’ shared vision is to give users a choice, rather than dictate what they use. We’re pleased to partner with Nemetschek on these important initiatives.”

“Our customers already enjoy the benefits of workflow integration between most of our products. This collaboration allows us to provide an overarching strategic layer on top of everything we do,” said Patrik Heider, spokesman and Chief Financial & Operations Officer (CFOO) of the Nemetschek Group. “This will better enable us to provide our customers with end-to-end workflow solutions that cover the entire AEC life cycle in a fully transparent and ‘open’ way.”

Trimble and Nemetschek will provide updates on specific collaborative initiatives as the relationship progresses.

IFC4 coordination view project underway

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.

IFC4 coordination view

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.’
