E. Hour (hr.): Measurement will be for the actual number of hours ordered and performed by the Contractor.

F. Pound (lb.): If sacked or packaged material is furnished, the net weight as packed by the manufacturer may be used.

G. Gallon (gal): 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.

H. Lump Sum (LS): 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.

No adjustment in contract unit price will be made for variations in quantity due to the differences in the specific gravity or moisture content.

Use net certified scale weights, or weights based on certified volumes.

1.07 Method of Measurement

One of the following methods of measurement for determining final payment is designated in the

Schedule of Items for each PAY ITEM.

A. Designed 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 designated in the Schedule of Items may be authorized under any of the following conditions:

1. Changes in the work authorized by the CO.

2. A determination by the CO that errors exist in the original design that cause a PAY ITEM quantity to change by 15 percent or more.

3. A written quantity of a PAY ITEM 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 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 measurement of completed work.
