General guidance and requirements for the 75% Geotechnical Report is provided here. Links to an external site.
Upload a pdf of your 75% report to Canvas and submit two (2) printed and bound copies of the geotechnical report at the beginning of class.
Examples of student geotechnical reports can be seen here Links to an external site. with the scored rubric shown here Links to an external site.. A second student geotechnical report can be found here Links to an external site. with the graded rubric shown here Links to an external site..
An additional example is provided here. Links to an external site.
A professional geotechnical report is shown here Links to an external site..
Reports, specifications, drawings typically go through a number of internal and external reviews before they are complete. Formal review at 30%, 60%, and 90% is common. Your team should conduct its own internal reviews before submitting this 75% review document.
The project may be modified during design, requiring revisions to this 75% Geotechnical report. Expect some modifications as a result.
In addition, comments and markups by the final review team (in this case your instructors) are likely and should be addressed by your team for the final submittal.
