1. Collaboration BIM Curriculum 05

2. Topics  Internal Collaboration  Office Organization  Teamwork  Hotlinks  Complex Projects

3. Collaboration in the Office  Sharing and coordinating the work between the project team members is one of the most important task of the project leader and the CAD manager  Project sharing method should be adequate for the project team size and the office organization  Advanced BIM programs provide effective solutions for this problem

4. Office Organization: Small Office Principal(s) Project Leader 1 (Part Time CAD Manager) Project Architect 1 Project Architect 2 Draftsman 1 Draftsman 2 Project Leader 2 Project Architect 1 Project Architect 2 Draftsman 1 Draftsman 2 Office Administration Organization  Two independent project teams  Two projects run at the same time  One project team contains 4-5 people  Small to medium scale projects  No full time CAD manager Problems  No dedicated person to establish and maintain office CAD and IT standards  Lack of professional design and visualization teams

5. Office Organization: Large Office Principal(s) Project Director Project Leader Architects Draftsmen Project Leader Architects Draftsmen Project Leader Architects Draftsmen Project Leader Architects Draftsmen Design TeamVisualization TeamIT ManagerCAD Manager Office Administration Organization  4 project Teams  Three projects run parallel (one big project)  Two project teams are working on a big project under the supervision of a project director  One project team contains 5-10 people  Full time CAD and IT managers  Independent design and Visualization Team supports the project architects Problems  Very strict CAD and IT standards are required  Project sharing in big design teams is difficult  Continuous communication between the design team and the project teams is necessary

6. Internal Collaboration-BIM Advanced BIM applications allow the seamless sharing of the BIM data between the project team members. The two most common project sharing methods are:  Teamwork concept  Hotlinked file method

7. The Teamwork Concept The Graphisoft Teamwork concept provides an effective and integrated solution for sharing the BIM data between the project team members:  Central file contains the complete virtual building database  Team members work on local copies  Team members have dedicated workspaces  Team members send and receive changes regularly Local Copy 1Local Copy 2Local Copy 3 Central BIM File Workspace 3 Workspace 2 Workspace 1 Send & Receive Changes User 1User 3User 2

8. Evaluation of TeamWork Benefits  Effective Team members can work simultaneously on the same project  Secure No overlapping workspaces. Team members can’t modify or delete accidentally the other’s work  Organized Team members have dedicated roles and rights  Transparent Team members can check the actual status of the project at any time  Controllable Team leaders can revise the changes made by the project team Limitations  Team members can’t send or receive changes simultaneously  The CAD manager has to set up a schedule for sending and receiving times

9. Team Members’ Role  Administrator coordinates the team and first share the Teamwork file so that the team members can sign in to it  Team Leader is the person responsible for the project  Teammate is any team member working on any part of the shared project.  Mark-up only add corrections or highlight elements that need to be checked or modified by other Teammates  View Only is able to access the shared project through the network but not allowed to make changes

10. Workspace Definition Workspaces can be reserved using a variety of methods to allow maximum freedom for project sharing:  Stories  Layers  Selection Marquee  Drawings (sections, elevations etc.)

11. Send & Receive Changes Users must regularly send and receive changes to keep the Teamwork file and the local copies up to date.  Changes made by any team member are sent to the shared Team Project by choosing Send & Receive Changes command, or (optionally) when signing out.  Changes sent to the Team Project do not appear automatically in other Teammates’ copies. In order to see changes made by another Teammate, they too have to choose Receive Changes.

12. More Teamwork Functions Teamwork offers many additional services for architects:  Password protection when signing in to a project  Revision history  Optional comments about each change  Changes can be reviewed by the team leader before sending them to the central file

13. The Hotlinked Files Concept Project File Hotlink Module Module File Nested Module Hotlink Module Module File Hotlink Module Hotlink  Using hotlinked files allows you to insert the contents of external files (sources or modules) into the currently open master project file (host)  Whenever the content of a source/module file is changed, the modifications automatically appear in all instances of the hotlinked modules placed in the host file  Typical hotlink solutions are the hotlinked modules in Archicad and external references (xRefs) in AutoCAD

14. Evaluation of the Hotlinked File Method Benefits  Hotlinks can be used effectively to manage repetitive elements in a project (e.g. rooms in a hotel)  Hotlinked files can also refer to other hot-links. That is called a nested module.  Hotlinks can be used to subdivide a larger building into smaller, easier-to-handle logical parts Limitations  Owner of the host file doesn’t have automatic control over the content of the hotlinked files  Changes of the hotlinked file can cause conflicts in the host project  Moving or deleting the hotlinked file will break the hotlink in the host

15. Complex Projects Hotlink Module XREF (dwg) TeamWork File 01 Documenta tion File Hotlinks TeamWork File 02 XREF 3D Model File for Visualization Hotlinks Independent Details Pictures Hotlink Module  In case of big or complex projects a custom collaboration solution is needed that is adequate for the office organization and the type of the project  Combination of Teamwork files, with hotlinked modules and external references can be effective even in case of very complicated projects
