AGC BIMForum: “BIM With Others”
What kind of BIM do you practice?“Lonely BIM” – use of tools for internal resultsLonely BIM – use of tools for internal results“Social BIM” – sharing of data with other constituents

Data exchanges in steel constructionWhat works:
Wireframes and gridsRelative geometry such as top of steel datumSome sizing if the designers modeled correctlySome sizing if the designers modeled correctlyQuantities

What doesn’t work:Material grades and sizes when approximation is used by a d i idesigner or engineerColumn rotation in data translationLack of curved geometry in SDNF formatg yEditing dimensions/text in lieu of real modelingAnecdotes of Revit to CIS/2 translation taking 24-30 hours

Insurance for IPD teams?Warning to designers using BIM: Means & Methods!
BIM MythsBIM requires a different project delivery method.When using BIM, you cannot tell who is responsible for what or who owns the model.When using BIM, anyone can change anyone else’s model.BIM blurs the distinction between design and construction.The architect is not in “responsible charge” of the design.You cannot have some information in the model and some only in 2D details.The model cannot be a contract document.Y t l th di i f th d lYou cannot rely on the dimensions of the model.The architect is subject to more lawsuits from contractors and subs because now there is direct privity of contract.
