All other work, labor, materials, equipment, and incidentals necessary to successfully complete the project will be considered as included in the payment for items shown. This section defines the method of measurements and basis of payment for work items listed in the Schedule of Items.

When more than one class, size, type, thickness, etc. is specified in the Schedule of Items for any pay item, suffixes will be added to the item number to differentiate between the pay items.

DETERMINATION OF QUANTITIES

The following measurements and calculations shall be used to determine contract quantities for payment.

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.

For excavation or embankment volumes, the average end area method shall be used to compute volumes. 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.

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

For items that are measured by the linear foot, such as pipe culverts, fencing, guardrail, piping, utilities, and underdrains, measurements shall be made parallel to the base or foundation upon which the structures are placed.

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

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.

UNITS OF MEASUREMENT

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

50lb Bag: Measurement will be for the actual number of 50lb bags of standard bentonite grout.

94lb Bag: Measurement will be for the actual number of 94lb bags of standard cement or grout.

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

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

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

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.

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

Gallons (GAL): The quantity shall be measured by any of the following methods:

Measured volume in container.

Metered volume by approved metering system.

Commercially package volume.

Hour (HR): Measurement will be for the actual number of hours (or fraction thereof) ordered by the Contracting Officer and performed by the contractor.

Linear Foot (LF): Measurement of work along its length from point-to-point; parallel to the base or foundation. Do not measure overlaps.

Lump Sum (LS): One complete unit.

Pound (LB): For sacked or packaged material, measurement will be the net weight as packed by the manufacturer.

Square Foot (SF): Measured on a plane parallel to the surface being measured.

Square Yard (SY): Measured on a plane parallel to the surface being measured.

METHOD OF MEASUREMENT

One of the following methods of measurement for determining final payment is designated on the Schedule of Items for each pay item:

ACTUAL QUANTITIES (AQ) - These quantities are determined from actual measurements of completed work.

DESIGNED QUANTITIES (DQ) - These quantities denote the final number or units to be paid for under the terms of the contract.
