The computational heart of the exam: traverse computation and adjustment, area, curves both horizontal and vertical, earthwork, and construction staking.
What this subject area expects
Compute latitudes, departures, closure and precision, and adjust by the compass rule
Solve simple horizontal curves and parabolic vertical curves and stake them
Compute areas by coordinates, by DMD, and with curved boundaries
Calculate earthwork volumes by average end area and by the prismoidal formula
