Trimble Buildings
Introducing: Trimble Buildings
Trimble DBO
• Aligns our technology and solutions to the markets
Engineering and Construction Segment
Latest additions • Manhattan software FM
• Gehry Technologies
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

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)
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
• …
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
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.

Partial models coexist

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…

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
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
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…
Are we educating for the past or for the future?
How can we get talented people interested in working in the AEC industry?
Flat pack Steel Delivery ready for assembly
Delivery to fabricator

21 BIM in fabrication Mick Hodgson
What's coming in BIM Fabrication ? Assembly
Robotic Welding
IFC the latest project now 27.6.2012
22 BIM in fabrication Mick Hodgson
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.

Also need for other semantic information
• Terrain models
• Cadastral information
• Zoning information
• Utilities
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
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

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
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.
