However, there are certain information items that Vulcan requires and certain limitations in the scope and use of these studies that contractors and owners alike should be made aware of.

All drivability and wave equation analyses are subject to the following disclaimer, which should be understood from the beginning:

THE CUSTOMER SHOULD RELY ON THESE ANALYSES ONLY AS A FIRST EVALUATION OF THE PROJECT. ANY OTHER USE OF THE DATA IS NOT ADVISED.

Users of the data should also understand that the reports are not sealed.
