(Mn/DOT) Geotechnical
Investigation Information Interchange Internet Interface (GI5)
Mn/DOT
geotechnical summary information is available in MS Excel format. Logs are
available in Adobe PDF file format; log information may also available in the
DIGGS XML data exchange format. (For more information, visit www.diggsml.com)

Users should be aware that many
historic records (prior to 1993) are archived in the GIS system with approximated
coordinate locations of relatively low precision (+/- 233 ft. X,Y); although the
original recorded locations based on roadway stationing, are usually within 1.0
ft accuracy. Care should be taken in using historic data as ground conditions
may have been altered by construction activities or by other means after the
original site investigation. Please refer to the new user ‘known issues” sheet
for further information. Not all boring logs are presently available
electronically. For more information, to provide comments, or to report errors
or omissions in data please contact the Mn/DOT
Foundations Unit at: gi5-database.dot@state.mn.us
Disclaimer:
Information available in the Mn/DOT electronic geotechnical database is accurate to a

original investigation. This GIS interface and database system is provided as
an aid to geotechnical practitioners; it is not intended to replace
geotechnical investigations for future projects. Although significant effort
has been made to ensure the data included in the geotechnical database is
accurate, Mn/DOT does not provide any warranty with
