USDA Forest Service Project Specifications

July 2018 Building Decommissioning 012000 - Page 5 of 5

1.0 SUMMARY

A. The basis for measurement and payment for all work performed under this contract shall be as listed in the Schedule/“Quote Form.” Unless the work is specifically called out to be measured and paid for in the Quote Form, payment for such work shall be included in other applicable items of the Quote Form. There shall be no separate measurement and payment for any such work not specifically listed in the Quote Form.

B. The Contractor shall complete unit and total pricing for ALL items. If “optional” items are presented the “optional” item work shall be quoted as mutually exclusive (stand-alone) items. The Contracting Officer and the government reserves the right to award individual optional items, as funding becomes available.

C. The Mobilization item is intended to compensate the Contractor for operations including, but not limited to, those necessary for the movement of personnel, equipment, supplies, and incidentals to the project site; for payment of premiums for bonds and insurance for the project; and for any other work and operations which must be performed or costs that must be incurred incident to the initiation of meaningful work at the site and for which payment is not otherwise provided for under the contract.

D. Items listed in the Quote Form as lump sum shall be on a lump sum all required basis. No direct measurement will be made for lump sum quoted items. Quote items calling for unit prices show estimated quantities of work to be performed. These quantities, although shown with as much accuracy as possible, are approximate only and Contractors should verify or determine their own quantities for quoting. Payment to the contractor shall be made based on the awarded amount according to The Schedule.

E. The summation of all quote items under the Quote Form shall equal all work required by the drawings and Specifications regardless of whether individual items of work are described under quote item descriptions or not. Payment shall be made at the contract unit quote or lump sum prices listed in the Schedule. The prices listed therein shall be payment in full for all labor, tools, equipment, materials, etc., which are required for the project according to the Contract Documents, including all work and materials incidental thereto.

F. Payment for unit quote items and lump sum quote items only partially completed at the end of monthly pay periods shall be based on a percentage of work completed as determined by the Government. An example is the construction of pipelines where the unit quote price includes the excavation and backfill of the trenches, installation of pipe, trench compaction, flushing and testing, although the Contractor may have installed a certain length of pipeline, yet has not completed the testing and/or restoration work. The actual payment for that quote item will be reduced to reflect the actual amount of work completed.

G. Capping and abandoning of existing water lines and demolition of water fixtures not specifically called out in a pay item but shown on the drawings is incidental to the work and no separate pay item will be included for this work.

H. For pipelines, the following method will be used to determine partial payment for work not complete unless determined otherwise by the Government:

Installed

Flushing, Pressure and Leakage Testing And Disinfection of Pipeline when Required 15%

For valves, meters, and other similar work items, the following method will be used to determine partial payment for work not complete:

Installed

Installation of Work Item to Finished Grade and Final Restoration 25%

1.1 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 computations 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 excavation or embankment volumes, the average end area method shall be used to compute volumes. However, if in the judgment of the Contracting Officer (CO), the average end area method is impractical, measurement shall be made by three-dimensional methods.

3. For Structures, they shall be measured according to neat lines shown on the drawings or as altered by the CO, in writing, to fit field conditions.

4. For items that are measured by the linear foot, such as pipe, utilities, and underdrains, measurements shall be made parallel to the base or foundation upon which the structures are placed.

5. For standard manufactured items (such as wire, pipe) 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.

1.2 UNITS OF MEASUREMENT

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

1. Cubic Yard (CY): A measurement computed by one of the following methods:

a. Excavation, Embankment, or Borrow. The measurement computed by the average end area method from measurements made longitudinally along a centerline or reference line.

b. Material in Place or Stockpile. The measurement computed using the dimensions of the in-place material.

c. 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.

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

3. Gallons (GAL): The quantity shall be measured by any of the following methods:

a. Measured volume in container.

b. Metered volume by approved metering system.

c. Commercially package volume.

4. Hour (HR): Measurement will be for the actual number of hours (or fraction thereof) ordered by the Contracting Officer and performed by the contractor.

5. Linear Foot (LF): Measurement of work along its length from point-to-point; parallel to the base or foundation. Do not measure overlaps.

6. Lump Sum (LS): One complete unit.

7. Square Foot (SF): Measured on a plane parallel to the surface being measured.

8. Square Yard (SY): Measured on a plane parallel to the surface being measured.

1.3 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:

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

2. 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, 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, and cause 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.
