Send one notice to trade contractors to access files, rather than dealing with email size and speed issues. Trade contractors can then review/download/print themselves as necessary. Send out Campaign Email blasts to the trades you want to invite, only a few simple clicks. Much easier than using Email or Fax and having to dig up email addresses and fax numbers.
As drawings and specs are revised, file revisions can be tracked and stored on Bid Intent. As an Estimator, you will be able to determine who viewed what files and at what time in case discrepancies in quoting arise. Find out who is bidding on what section/division to ensure you have full coverage for your quote; any missing pieces will be instantly identifiable and allow you to send out another Invitiation to Tender to gain better coverage.
