MEASUREMENT AND PAYMENT

1. PART 1 - GENERAL

1.01 SUMMARY

A. 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, labor, materials, equipment, and incidentals necessary to successfully complete the project will be considered as included in the payment for items shown. This section defines the method of measurements and basis of payment for work items listed in the Schedule of Items.

B. Not all units and measurement methods may be used under this Contract.

1.02 DETERMINATION OF QUANTITIES

A. The following measurements and calculations shall be used to determine contract quantities for payment.

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

2. For items that are measured by the linear foot, such as pipe culverts, fencing, guardrail, piping, utilities, and underdrains, measurement shall be made parallel to the base of foundation upon which the structures are placed.

3. 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.

1.03 UNITS OF MEASUREMENT

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

1. Each (EA): One complete unit, which may consist of one or more parts.

2. Linear Foot (LF): Measurement of work along its length from point-to-point;

parallel to the base or foundation. Do not measure overlaps.

3. Lump Sum (LS): One complete unit, not directly measured. The bid amount is complete payment for all work described in the contract and necessary to complete the work for that item.

1.04 METHOD OF MEASUREMENT

A. One of the following methods of measurement for determining final payment is designated on the Schedule of Items for each pay item:

Rev. Date 2/2022 Union Creek Well Pump Replacement 01025 - 2/3 Measurement and Payment

1. ACTUAL QUANTITIES (AQ) - These quantities are determined from actual measurements of completed work.

2. DESIGNED QUANTITIES (DQ) - 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, 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:

a. As a result of changes in the work authorized by the CO.

b. As a result of the CO determining that errors exist in the original design that causes a pay item quantity to change by 15 percent or more.

c. 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.

3. 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 shall not be measured.
