Seoul, November 2-8, 2002 German National
Activity Report

• Contents
• Market situation of AEC CAD-software
• AEC Research Program of the German Ministry for
  Education and Research
• Activities related to VDA
• Activities related to governmental authorities
• German Project ODABAU
• EC Project FunSTEP DIS
• EC project PRODAEC

Market situation of AEC CAD-software

• Little changes since Stockholm meeting
• Continued severe recession of construction
  industry for several years in a sequence no
  prospects for recovery
• Only construction companies mainly working abroad
  or providing a full service finance, design,
  construct and operate are successful
• Hard time for system vendors for the AEC
  industry, especially CAD-system vendors
• Dramatic losses of value at the stock exchange
  market (up to more than 95)
• Continue to produce losses
• Concentration on core business, for example CAD
  or building specification systems
• Increased tendency to cooperate
• Tendency to switch from national CAD systems to
  international CAD systems

AEC Program of the German Ministry for Education
and Research (1/2)

• 5 Years program with an overall volume of approx
  45 million US
• Covers all kinds of AEC research, not only IT in
  AEC
• Two STEP related projects
• Usually 50 funding
• Reduction in 2002 and following years due to
  budget problems of German Government

4
AEC Program of the German Ministry for Education
and Research (2/2)

• STEP related Project
• ODABAU Integrated design and construction using
  project web servers. Basically Web server for any
  kind of construction documents, CAD files will be
  stored in STEP-CDS format
• Budget 2 Million US,
• Original Duration January 2001 December 2002,
  was extended for 9 months to September 2003
• Web based document and drawing management has
  been set up
• New attempt to establish easy to use layering
  guidelines with the goal to share layer and to
  avoid to redraw existing information
• Training of small design offices has been done
• Intensive testing by construction company Ed.
  Zueblin and design offices
• Start of pilot project was delayed
• Parallel design (conventional and web) based to
  evaluate benefits of web based project management
• Final Goal Handbook for Web based project
  management including document management

STEP-CDS Acceptance and projects

• Acceptance
• Licenses now in all major car companies
• Two new CAD systems joining the initiative
• Four states of Germany adopting STEP-CDS
• Projects VDA related projects
• Extension of the DaimlerChrysler Factory in
  Tuscaloosa USA
• New BMW factory in Leipzig
• As built documentation of DaimlerChrysler Plant
  50 in Sindelfingen
• DaimlerChrysler factory Marienfelde, Berlin
• Refurbishment of Hall 4 and new communication
  centre of the AUDI factory in Ingolstadt
• Extension of the University of Hannover
• Skypeer tower (DEKA real estate, 60 Storeys, 450
  million investment) in Frankfurt
• STEP-CDS implementations enable more design
  offices to participate in design projects with
  their system. They are no longer forced to use
  the System of their client.

Development activities related to VDA

• General properties mechanism proposal discussed
  with Max Ungerer
• Draft proposal has already been incorporated into
  STEP-CDS, implementation is in place
• Review and Discussion of mechanisms to
  incorporate raster images (together with
  Seong-Sig Kim and Max Ungerer)
• Survey on 3D-CAD data exchange requirements
  (digital factory paradigm)
• Testing of existing AP214 implementations
• Actual 3D-CAD Factory environment (Huge amount of
  data, mixed results)
• Further testing of 18 small 3D Test cases, of
  increasing complexity
• Start of the development of a STEP based facility
  management system
• First goal space management

Some 3D test examples

AP225 based data exchange project (1/2)

• Basis STEP AP225 implementations in practical
  usage such as the exchange of 55 facilities of
  the city of Hamburg (3D building models)
  continues
• Change of CAD system from RIBCON to ALLPLAN
• Most demanding type of data exchange since client
  wants to use the data as if they were created in
  the new system
• Finally started in January 2002
• Mismatch between sending and receiving system
• Modern buildings almost no problems
• Client requires specific wall types in ALLPLAN,
  does not accept so called polygon walls
• New capability was incorporated in ALLPLAN
• Still some afterwork is required if old buildings
  (beginning of 20th century) with sculptured walls
  will be exchanged or
• Autonmatically surveyed walls were point in
  spaces were surveyed and the walls, openings etc.
  generated by software.

EC Project FunSTEP DIS

• Uses the Application Module approach
• Most of them in an advanced stage of development
  and extracted from AP214 (Automotive AP)
• Includes 5 modules to represent buildings,
  extracted from AP225
• Building components
• Building items
• Building structure
• Location in building
• Building shape
• In total approx. 20 building related entities
• Use of existing modules to represent geometry,
  non geometric attributes, classification etc.
• Can be used by other APs

13
EC Project Prodaec (1/2)

• Topic Thematic Network
• Work packages
• WP1 Management
• WP2 National Information Points
• WP3 Industrial Needs
• WP4 Standards
• WP5 Electronic Business
• Started February 2002
• Kick off meeting 18./19. February 2002
• First review meeting September 9th 2002,
  evaluation of current status

14
EC Project Prodaec (2/2)

• Evaluation of Harmonization
• IFC2X EXPRESS-G as colored wall paper (DWG),
  indicating the subset to be established as ISO
  PAS and entities where similar SC4 entities
  exist, mostly from STEP (WH)
• EXCEL Spreadsheet with all IFC2x entities as a
  basis for the assessment of harmonization issues
  (WH)
• Assessment of IFC2X platform geometry differences
  with STEP Part 42 and proposals for harmonization
  (WH)
• White paper of harmonization of IFC geometry
  where there is not direct equivalent in STEP part
  42, done by (RG)
• Comments to the Assessment (WH)
