MEASUREMENT AND PAYMENT

PART I - GENERAL

1.1 Measurement and Payment - Measurement and payment for contract work will be made only for and under those pay items included in the SCHEDULE OF ITEMS. All other work and materials will be considered as included in the payment for items shown.

When more than one class, size, or thickness is specified in the SCHEDULE OF ITEMS for any pay item, suffixes will be added to the item number to differentiate between items to be bid.

1.2 Determination of Quantities - The following methods of measurement are used to determine contract quantities for payment.

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

Structures will be measured according to neat lines SHOWN ON THE DRAWINGS or as altered by the COR in writing to fit field conditions.

For standard manufactured items, such as fence, wire, plates, rolled shapes, pipe conduits, etc., identified by gauge, weight, section dimensions, etc., such identification shall be considered the nominal weights or dimensions. Unless controlled by tolerances in cited specifications, manufacturer's tolerances will be accepted.

1.3 Units of Measurement - Payment will be by units defined and determined according to U.S. Standard measure as follows:

A. Acre – Make longitudinal and transverse measurements for area computations horizontally.

B. 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.

2. Material in Place or Stockpile - The measurement computed with 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.

C. Cubic Yard Mile - A combination of linear and volumetric measurement meaning the movement of a cubic yard of material 1 mile.

D. Each - One complete unit, which may consist of one or more parts.

E. Gallon – The quantity may be measured by any of the following methods:

1. Measured volume container.

2. Metered volume. Use an approved metering system

3. Commercially packaged volumes.

F. Hour – Measurement will be for the actual number of hours ordered and performed by the Contractor.

G. Linear Foot – Measure from end to end, parallel to the base or foundation being measured, or horizontal.

H. MFBM - One thousand board feet measure based on nominal widths, thickness, and extreme usable length of each piece of lumber or timber actually incorporated in the job.

I. Mile – Measure horizontal along the centerline of each roadway, approach road, or ramp.

J. Pound – If sacked or packaged material is furnished, the net weight as packed by the manufacturer may be used.

K. Square Foot - Measure on a plane parallel to the surface being measured or horizontal.

L. Square Yard – Measure on a plane parallel to the surface being measured or horizontal.

M. Station - One hundred linear feet measured horizontally.

N. Station Yard - A combination of linear and volumetric measurement meaning the movement of a cubic yard of material one station.

O. Thousand Gallons Mile - A combination of linear and volumetric measurement meaning the movement of 1,000 gallons of material 1 mile.

P. Ton - Short ton consisting of 2,000 pounds.

Q. Ton Mile - A combination of linear and weight measurement meaning the movement of 1 ton of material 1 mile.

1.4 Methods of Measurement - One of the following methods of measurement for determining final payment is DESIGNATED on the SCHEDULE OF ITEMS for each pay item:

A. Contract Quantities (CQ) AND Design Quantities (DQ) - These quantities denote the final number of units to be paid for under the terms of the contract. They are based upon the original design data available prior to advertising the project.

Original design data include the preliminary survey information, design assumptions, calculations, drawings, and the presentation in the contract. Changes in the number of units SHOWN in the SCHEDULE OF ITEMS may be authorized under any of the following conditions:

1. As a result of changes in the work authorized by the Contracting Officer.

2. As a result of the Contracting Officer determining that errors exist in the original design data used to determine designed quantities that cause a pay item to change by more than 15 percent.

3. As a result of the Contractor submitting to the Contracting Officer a written request showing evidence of errors in the original design data used to determine design quantities that cause a pay item total to change by more than 15%. The evidence must be verifiable and consist of calculations, drawings, or other data that show how the designed quantity is believed to be in error.

B. Staked Quantities (SQ) - These quantities are determined from staked measurements prior to construction.

C. Actual Quantities (AQ) - These quantities are determined from measurements of completed work.

D. Vehicle Quantities (VQ) - These quantities are measured or weighed in hauling vehicles.

E. Lump Sum Quantities (LSQ) - These quantities denote one complete unit of work as required by or described in the contract, including necessary materials, equipment, and labor to complete the job. They will not be measured.
