  2. Building Information Modeling • Still the main goal is to generate drawings of the construction for various purposes • Each construction team member requires drawings • Can we use BIM/3D to improve the overall drawing creation workflow

  3. Contract docs Sketches & calcs A & D Advanced Large Sheet GA drawings Connection details Engineering GA drawings Cast Unit / Shop tickets Basic Basic Traditional Method/Workflow • Drawing information usually combined into very busy detail drawings. Sometimes 8-1/2” x 11” • Contained architecture, weld, plate, and other information all together • Many to do and track, very time consuming (200-300) drawings to track • Then must track thousands of reference calls to (marks/symbols) GA showing which detail drawing

  4. Contract docs Sketches & calcs A & D Advanced Large Sheet GA drawings Connection details Engineering With a model do we need GAs to do shop tickets? With a model do we need drawings for approvals? Do we need fabrication level of detail in these drawings? Lets simplify drawing for the correct audience! GA drawings Cast Unit / Shop tickets Basic Basic Traditional Method/Workflow

  5. Erector Fabricator Architect Engineer Team Member Drawings Key is all have slightly different uses Fabrication info for production & schedule Info for approvals (mainly connxs) how to weld & put building together Arch details How reveals line up

  6. Erector Fabricator Architect Engineer Team Member Drawings With 3D models does fabrication need so many details? We used to do them so that others could make shop drawings. Should we have less detail in them OR do them at different stage? Can engineering offices use models, shop drawings, or GA drawings to approve design or do we still need these traditional small detail drawings combing engineering, fabrication, architectural, and erection information? Erectors are concerned with welds and geometry fit dimensions, not so much studs and embed information, can there be a set of “connection” drawings that contains only the “erection” information? Can architects offices use models, shop drawings, or GA drawings for approvals?

  7. Connection drawings • Drawings to show placement of embed for sharing information to 3rd party. • To show how to weld, bolt, and erect pieces on the job site…”how to put the building together.” • These are done before reinforcing the model and before most shop drawings in stages as information is available.

  8. Current Connection Drawings… Current procedure: • Create views of component • Create new GA drawing of views • Edit drawing to add information • Move drawing later when connx. moves in model, re-edit drawing • Create hundreds of section and details symbols referring to where to find connx. drawing in project – for GA erection • Update/edit GA drawings to fix reference to changed connection in model (loop several times steps 3-6 typically, for many connxs) New procedure: • Tell TS to create connection Drawings.(selected, all, etc…) • Edit drawings as necessary

  9. Conclusion • Significant Productivity gains for projects • Reduction in errors • Automation of tedious, unpleasant task of creating and views that could move • Drawings at earlier stage to coordinate project has a lot of value

  10. Product - .NET development • Current procedure: • Create views of component • Create new GA drawing of views • Edit drawing to add information • Move drawing later when connx. Moves in model, re-edit drawing • Create hundreds of section and details symbols referring to where to find connx. Drawing in project – for GA erection • Update/edit GA drawings to fix reference to changed connection in model • (loop several times steps 3-6 typically, for many connx.s) Connection Drawings • Create Empty Drwg • Create Dummy GA Drwg • Cut Section in Dummy GA • Move section to empty drwg • Add views • Edit…

  11. Product - .NET development • Create Empty Drwg • Create Dummy GA Drwg • Cut Section in Dummy GA • Move section to empty drwg • Add views • Edit… • Push button • Edit…

  12. Product - .NET development

  13. Product - .NET development “The process of marking connections in the model,  keeping track of which connections have which marks, and naming the detail drawings for each connection correctly is rather tedious with lots of room for user error.  The tool that Charles has created makes this process much faster and far less prone to errors … I plan on making this tool part of our modeling/detailing process on projects moving forward.” - Jason Reffner, Newcrete “The new component manager tool is a great addition to Tekla, allowing precast users to easily manage and create connection drawings using localizations built into Tekla or their own custom settings.  This tool should help expedite the erection drawing process.” - Dave Foley, High
