a. For individual construction items, longitudinal and lateral measurements for area computations shall be made horizontally or corrected to horizontal measurement unless otherwise specified. Measurements for geotextiles, netting and erosion control blankets shall be along slope lines.

b. The average end area method shall be used to compute volumes of excavation or embankment. However, if in the judgment of the Contracting Officer (CO), the average end area method is impractical, measurement shall be made by volume in hauling vehicles or by other three dimensional methods.

c. Structures shall be measured according to neat lines shown on the drawings or as altered by the CO, in writing, to fit field conditions.

d. For items that are measured by the linear foot, such as pipe culverts, fencing, guardrail, and under drains, measurements shall be made parallel to the base or foundation upon which the structures are placed. Pipes shall be measured along center of invert.

e. For aggregates weighed for payment, the tonnage shall not be adjusted for moisture content, unless otherwise provided for.

f. For standard manufactured items--such as fence, wire, plates, rolled shapes, pipe conduits--identified by gauge, weight, section dimensions, and so forth, such identifications shall be considered the nominal weights or dimensions.

Unless controlled by tolerances in cited specifications, manufacturer's tolerances shall be accepted.

F. Units of Measurement:

1. Payment shall be by units defined and determined according the U.S. Standard measure and by the following:

2. Cubic Yard (CY): A measurement computed by one of the following methods:

a. Excavation, Embankment, or Borrow. The measurement computed by the average end area method from measurements made longitudinally along a centerline or reference line.

b. Material in Place or Stockpile. The measurement computed using the dimensions of the in-place material.

c. Material in the Delivery Vehicle. The measurement computed using measurements of material in the hauling vehicles at the point of delivery.

Vehicles shall be loaded to at least their water level capacity. Leveling of the loads may be required when vehicles arrive at the delivery point.

3. Each (EA): One complete unit, which may consist of one or more parts.

4. Linear Foot (LF): Measurement of work along its length from point-to-point;

parallel to the item being measured. Do not measure overlaps.
