Paper Documents into a PDF

Electronic Documents Requirement

  • We do not accept paper documents. Please submit electronic PDF documents.
  • We recommend creating plans and other documents electronically. It will be easier to edit them later if revisions or corrections need to be made.

Paper Documents

If you must use paper documents:

  • Each paper document should be scanned all at once into a single electronic PDF document.
  • This can be accomplished at home, by your contractor or engineer, or at a local copy shop.
