This document discusses OpenBIM, BIM, and geospatial integration and standardization. It covers Trimble's evolution across various industries and introduces their Buildings division. It defines BIM and discusses openBIM. It also discusses challenges with BIM adoption and modeling across phases. The document outlines a system architecture for BIM and why semantic data is important. It covers areas like augmented reality, robots, and how education needs to prepare people for the future of these technologies in AEC. Other topics include BIM in fabrication, infrastructure BIM, and challenges with indoor navigation.
![BIM, software, process, technology or what?
No practical consensus of what BIM is
Every presenter still today includes a what is BIM section
Most common perception of people in the industry is that
BIM is software.
Other often used: Process, Model, Populated Database
describing facility
My favorite: BIM is a Technology

- 6. BIM Graphics to objects and geometry 6 Drawings are graphics (appearance important) A BIM consists of objects that may contain geometry and/or attributes (structure important)
- 7. BIM – Structured data DRUM - Distributed information management Functional objects Physical objects Logical objects Abstract objects Objects describing building Objects describing process • Schedules • Resources • Costs • Quality assurance • Tasks • Work • Approvals • RFI:s • Submittals • …
- 8. openBIM definition openBIM means that BIM operations and BIM data is not tied to any specific tool, software or vendor. – Freedom to choose the tools best suited for the purpose. – Freedom to transfer data between tools. – Freedom to develop very purpose specific tools independent of any platform. Open standard data formats (IFC, CityGML, KML…) are used for communication

- 11. Ambiguous modeling, different phases 11.3.2015 11Leif Granholm Architectural Engineering Detailing
- 12. Reference model principle Application capable of presenting and using native objects and objects in foreign schemas (IFC)simulaneously Foreign information not bulk converted to native schema. 11.3.2015 12Leif Granholm Native objects IFC objects (retained in IFC format)

Structural steel detailing Structural site production MEP design MEP fabrication MEP production Partial models coexist throughout the Project
- 14. Paradigm shifts in Information Processing Information and Information Technology becoming a utility, everything in the cloud, user does not need to care where it comes from Information transforming from human readable documents to structured semantic data that can be processed automatically H2H, borders between humans coming down, countries, organizations, projects. Humans as the top of hierarchy, participating in several structures, Enterprise, Public organizations, Projects… 14
- 15. System and information architecture for BIM Three tier system architecure – Current native applications with native proprietary schemas for intelligent and parametric modelling optimized for the task and discipline at hand – Publishing platforms by all major BIM vendors, fed by the native applications, using IFC:ish schema. Most of information usage applications written against this tier. – Publishing platforms interoperate using IFC and Linked data 15
- 16. Why semantic data? Technology development enables automatic use of data – Robots (good example ping pong playing robot) – Augmented reality taken to next step by Google Tango project – Drones used for many purposes 16
- 17. Augmented reality & wearable computers… Kopin Golden-i Google Glasses use an automatic connection to the cloud to provide access to enormous amounts of information, data and applications…
- 19. Are we educating for the past or for the future? How can we get talented people interested in working in the AEC industry?
- 20. Fabrication BIM
- 21. Flat pack Steel Delivery ready for assembly Delivery to fabricator 27.6.2012 21BIM in fabrication Mick Hodgson
- 22. What's coming in BIM Fabrication ? Assembly Robotic Welding IFC the latest project now 27.6.2012 22BIM in fabrication Mick Hodgson
- 23. Using IFC for machine and ERP communication Current formats used are 2D (DSTV, dwg) Assembly automation using industrial robots is coming – 3D information required Project by AISC, Georgia Tech, Tekla, FICEP, Steel Projects and others to create MVD:s to be used in fabrication See http://www.aisc.org/BIMsteel.aspx for more info specially Automating Steel Fabrication section. 23
- 24. Also need for other semantic information • Terrain models • Cadastral information • Zoning information • Utilities
- 25. BIM – GeoSpatial integration very hot topic • Several standardization initiatives ongoing – ISO BIM-GIS Ad hoc group – OGC – buildingSMART MOU and joint project about alignments – Extending IFC for Infrastructure projects – InfraBIM • Roads, Railways, Bridges, Tunnels, Dams etc – Joint project to develop conceptual schema of alignments for InfraGML and IFC – Initiative to generate CityGML and IndoorGML from IFC • UK BIM Task Group – Very ambitious project by UK to use BIM technology in all public projects by 2016 • VCON project by Dutch and Swedish traffic authorities to use BIM for whole life cycle of reoads and railways
- 26. InfraGML and IFC buildingSMART and OGC cooperation Cooperation around BIM for Infrastructure – LandXML only existing standards but development weak – Autodesk and Bentley approached OGC to “take over” LandXML in 2012, bS openINFRA also interested – OGC started first Land Development DWG and then Land Development SWG to take on work – First task to create conceptual schema of LandXML in UML by reverse enginering, mostly by Paul Scarponcini from Bentley – Results from Frascati OGC meeting: -schema is too broken for compatible continuation -future with InfraGML and IFC for infrastructure in cooperation with bS, -scoping IFC for construction and GML for other purposes -name changed to Land and Infrastructure DWG/SWG 26
- 27. use case driven subset of LandXML functionality interoperability standard vs. negotiable template SDO support avoid possible legal issues enables OGC baseline consistency GML provides: – feature model – geometry support – coordinate reference systems – linear referencing – TIN support – compatibility with CityGML, TransXML LandXML InfraGML Proposal
- 28. Indoor Navigation Is going to be a huge issue for the BIM and GeoSpatial communities in the near future Situation absurd and unbalanced now, outdoor navigation ubiquitous globally but indoors, nothing ILA developing indoor positioning Data supply for this is going to be a big issue, volume >100 more than outdoor navigation, hundreds of thousands of data suppliers -> standard distributed information architecture and business model needed.
