TABLE OF CONTENTS During the planning phase of a geotechnical data management project, a survey must be conducted to determine the types of geological data available, the formats to be accounted for, and the possible exceptions. The checklist presented provides a starting point for the DBM when conducting surveys and interviews with end-users. A similar checklist should be developed for geophysical data where needed.
