Work measured and paid for under one pay item will not be paid for under any other pay item.

906.02 Determination of Quantities. The following measurements and calculations are used to determine contract quantities for payment.

For items that are measured by the linear foot, station, or mile measurements will be made along the centerline and parallel to the specified grade or foundation, unless otherwise Shown on the Drawings.

906.03 Units of Measurement. Payment will be by units defined and determined according to U.S. standard measure and by the following.

(A) Lump Sum (LS) The quantities that denote one complete unit of work as required by or described in the contract, including necessary materials, equipment, and labor to complete the job.

(B) Linear Foot (LF) Measurement of 12 inches along a reference line.

(C) Mile 5,280 Linear feet along a reference line.

(D) Cubic Yard (CY) The measurement computed by the average end area method from measurements made longitudinally along a centerline or reference line.

(E) Each (EA) One complete unit which may consist of one or more parts. The quantity is the actual number or units completed and accepted.

(F) Hour (H) Measurements will be for the actual number of hours performed by the contractor.

906.04 Methods of Measurement. One of the following methods of measurement for determining payment is Designated on the Schedule of Items for each Pay Item.

(A) Actual Quantities. (AQ) these quantities are determined from measurements of completed work.

(B) Lump Sum Quantities. (LSQ) these quantities denote one complete unit of work as required by or described in the contract, including necessary material, equipment, and labor to complete the job.

(C) Contract Quantities. (CQ) These quantities denote the final number or 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 and drawings. Changes in the number of units Designated in the Schedule of Items maybe authorized under the following:

1. As a result of changes in the work approved by the CO.

2. As a result of the CO determining that errors exist in the original design that cause a Pay Item quantity to change by 15 percent or more.

3. As a result of the contractor submitting to the CO a written request showing evidence of errors in the original design that cause a Pay Item quantity to change by 15 percent or more. 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.
