DEFINITION OF CONTRACT ITEMS

AND

MEASUREMENT AND PAYMENT

PART 1 - GENERAL

1.1 SUMMARY

A. The intent of this section is to explain, in general; what is and what is not included in a contract item; the limits or cut-off points where one item ends and another begins; and method of measurements and basis of payment for work items listed in the Schedule of Items.

B. Work: Furnishing all labor, materials, equipment, and other incidentals necessary to successfully complete the project or any portion of it, and carrying out all duties and obligations imposed by the contract on the Contractor.

C. Payment: For each individual item listed here and in the Schedule of Items, payment shall be full compensation for all work related to the particular item in accordance with these specifications and as shown on the drawings.

D. Measurement and payment for contract work shall be made only for and under those pay items included in the Schedule of Items. All other work and materials shall be considered incidental or as included in the payment for items shown

1.2 DETERMINATION OF QUANTITIES

A. Quantity Measurements:

1. Make all measurements for computation of quantities for all work items except those specified for payment by Designed Quantity (DQ) or Lump Sum Quantity

(LSQ).

2. Compute the quantities for periodic progress payments. The Contracting Officer shall compute the quantities for the final payment based on measurements taken by the Contractor.

3. Contractor measurements are subject to verification.

4. Submit all field notes, calculation sheets, and other data used to determine quantities.

5. Certify in writing as to the accuracy of the measurements and computations submitted.

B. Use the following measurements and calculations to determine contract quantities.

1. For individual construction items:

SUPERVISOR’S OFFICE 010250-2

MEASUREMENT AND PAYMENT

a. Longitudinal and lateral measurements for area computations: Make horizontally or corrected to horizontal measurement unless otherwise specified.

b. Measurements for geotextiles, netting and erosion control blankets: Make along slope lines.

2. Use the average end area method to compute volumes of excavation or embankment. However, if in the judgment of the Contracting Officer (CO), the average end area method is impractical, make measurement by volume in hauling vehicles or by other three dimensional methods.

3. Structures: Measured according to neat lines shown on the drawings or as altered by the CO, in writing, to fit field conditions.

4. For items that are measured by the linear foot, such as pipe culverts, fencing, guardrail, and underdrains: Make measurements parallel to the base or foundation upon which the structures are placed. Measure pipes along center of invert.

5. For aggregates weighed for payment: Don not adjust tonnage for moisture content, unless otherwise specified or indicated.

6. 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.

1.3 UNITS OF MEASUREMENT

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

B. Lump Sum: Do not measure directly. The bid amount is complete payment for all work described in the contract and necessary to complete the work for that item.

C. Square Feet: Longitudinal and transverse measurements for area computations will be made horizontally. Do not make deductions from the area computation for individual items having an area of 1 square foot or less.

D. Acre: 43,560 square feet. Make longitudinal and transverse measurements for area computations horizontally. Do not make deductions from the area computation for individual exclusions having an area of 500 square feet or less.

E. Cubic Yard: A measurement computed by one of the following methods:

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

MEASUREMENT AND PAYMENT

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

3. 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.

F. Each: One complete unit, which may consist of one or more parts.

G. Linear Foot: Linear feet measured horizontally.

H. Square Yard: 9 square feet. Longitudinal and transverse measurements for area computations will be made horizontally. Do not make deductions from the area computation for individual fixtures having an area of 9 square feet or less.

I. Ton: 2000 pounds. No adjustment in contract price will be made for variations in quantity due to differences in the specific gravity or moisture content. Use net certified scale weights, or weights based on certified volumes.

1.4 EARTHWORK TOLERANCES

A. Where tolerances are shown in the contract, they are intended to define reasonably close conformity. Adjustments of horizontal or vertical alignment, within the tolerances specified in this contract, or shifts of balance points up to 100 feet shall be made by the contractor as necessary to produce the designed roadway sections and to balance earthwork. Such adjustments shall not be considered as "Changes".
