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.

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.

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.
