1.03 DETERMINATION OF QUANTITIES

A. The following measurements and calculations are used to determine contract quantities.

B. For individual construction items, longitudinal and lateral measurements for area computations will be made horizontally or corrected to horizontal measurement unless otherwise specified.

C. The average end area method will be used to compute volumes of excavation or embankment.
