In the past we’ve been asked by Contractors and their subs to provide our cad files to them for use in generating shop drawings.
We typically allow this but require them to sign an indemnification form before sending them over.
We don’t see a problem with this but recently we’ve been asked by bidders, before the contract is even awarded, for our BIM models (Revit).
The concern with doing this is that the BIM models don’t necessarily include all the details and features of our design in the model itself since with Revit you develop the model only to a certain level of detail and then finish it off in the 2D drafting process.
So by giving them the model we are concerned that they will inadvertently depend solely on the model and miss things that are required in the actual contract documents. Apparently there are software products out there that do quantity take offs from the models.
Also, during bidding there is not a current set up contractual relationship between parties so that is concerning with respect to liability and the requirements on the bidders to follow due diligence.
Have you all experienced this type of request during bidding? What do you do about it?
