sections and can be used to compare design sections with as-built
sections. The tunnel sections need to make a closed loop. The
report includes the end areas and volumes for each section. For the
comparison, the report includes the over cut and under cut end
areas and volumes. Over cut is area from the 2nd section file that
goes outside the 1st section file. Under cut is area from the 1st
section file that goes outside the 2nd section file.
