Hello,
We typically only give out the base plans (floor plan, overall lighting plan, RCP, duct layout, structural grid, etc) upon request to sub-contractors for the sole purpose of assisting with shop drawings. We only do this upon request and we have them sign and return an indemnification form. Our indemnification form states in a legalese format that:
- use of this data is at the sole risk of the contractor and indemnifies the AE for any damages, fees, claims, etc that arise out of the use of this data
- electronic data cannot be controlled and therefore contractor is responsible for verifying the validity of the information and to follow the printed contract documents
- the AE assumes no responsibility for the submitted data as electronic files cannot be controlled once they leave the AE
There may be other provisions and putting it in legalese adds items.
I would recommend having the indemnification form and only giving the bare minimum of base plans the contractor actually needs to complete the work. Sending over your details, sections etc usually provides no benefit.
I would also recommend having a conversation with them regarding how they intend on using transmitted CAD files for building layout. You want to make sure that the contractor keeps the responsibility for laying out the building and not just rely upon your cad files which we all known may not be 100% accurate and could cause problems during layout. The contractor develops their own layout drawings.
Hope this helps

We are being asked by the general contractor to provide them with our full set of drawings in CAD format to allow them to use them for building layout, as built drawings etc.
On past projects we have, for a nominal fee, given them building templates that we take our name of and make them sign a disclaimer saying the drawings may not be the final CD,s and they use them at their own risk to allow them to do shop drawings etc.
I am just a little leery of giving them the entire set in a format. they can manipulate.
Just wondering what others are doing.
Thanks for your input!
