Pay Item - Numbering system and work description to remain the same.

Pay Unit - Pay unit(s) DESIGNATED IN THE SCHEDULE OF ITEMS have been changed from metric to the corresponding unit of U.S.

Standard English measure.

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

(a) Cubic Yard in Place. Measure solid volumes by the average end area method as follows:

(1) Measure cross sections of the original ground and use with design or staked templates, or take other comparable measurements to determine the end area. Do not measure work outside of the established lines or slopes.

96 SPS 106-1 (07/12/10)

(2) If any portion of the work is acceptable, but is not completed to the established lines and slopes, remeasure cross sections or comparable measurements of that portion of the work. Deduct any quantity outside the designated or staked limits. Use these measurements to calculate new end areas.

(1) Compute the quantity using the average end areas multiplied by the horizontal distance along a centerline or reference line between the end areas. Deduct any quantity outside the designed or staked limits.

Where it is impractical to measure material by the average end area method, other approved methods involving three-dimensional measurements may be used.

Measure liquid volumes in accordance with SPS Subsection 106.03(h).

(b) Cubic Yard in the Hauling Vehicle. Measure the cubic yard volume in the hauling vehicle using three-dimensional measurements at the point of delivery. Use vehicles bearing a legible identification mark with the body shaped so the actual contents may be readily and accurately determined. Before use, mutually agree in writing upon the volume of material to be hauled by each vehicle. Vehicles carrying less than the agreed volume may be rejected or accepted at the reduced volume.

Level selected loads. If leveling reveals that the vehicle was hauling less than the approved volume, reduce the quantity of all material received since the last leveled load by the same ratio as the ratio of the current leveled load volume to the agreed volume. Payment will not be made for material in excess of the agreed volume.

Material measured in the hauling vehicle may be weighed and converted to cubic yards for payment purpose if the conversion factors are mutually agreed to in writing.

Compute quantity by using measurements of material in the hauling vehicles at the point of delivery. Load vehicles to at least their water-level capacity. Leveling of the loads may be required when vehicles arrive at the delivery point.

(c) Cubic Yard Mile. A combination of linear and volumetric measurement meaning the movement of a cubic yard of material one(1) mile.

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

96 SPS 106-2 (07/12/10)

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

(f) Lump Sum. 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.

(g) MBF. One thousand feet board measure based on nominal widths, thickness, and extreme usable length of each piece of lumber or timber actually incorporated in the job. For glued laminate timber, 1,000 board feet based on actual width, thickness, and length of each piece actually incorporated in the job.

(h) Gallon. The quantity may be measured by any of the following methods:

a. Measured volume container.

b. Metered volume. Use an approved metering system.

c. Commercially packaged volumes.

(i) Station. One hundred linear feet measured horizontally.

(j) Station Yard. A combination of linear and volumetric measurement meaning the movement of a cubic yard of material one station.

(k) Square Yard. Measure on a plane parallel to the surface being measure or horizontal.

(l) Thousand Gallons Mile. A combination of linear and volumetric measurement meaning the movement of 1,000 gallons of material one(1) mile.

(h) Ton. Short ton consisting of 2,000 pounds. Use net certified scale weights based on certified volumes.

(m) Ton Mile. A combination of linear and weight measurement meaning the movement of one(1) ton of material one(1) mile.”

"(3) Description of the testing facilities and information on when and where each of the required materials tests will be performed.

(4) Random sampling and/or measurement plan prepared in accordance with requirements in Table 160."

(5) A log of all samples that are taken by the Contractor shall be maintained for the duration of the contract, and provided to the Contracting Officer upon request. Test results on all samples shall be given directly to the Contracting Officer within 8 hours of test completion."

160.03 Sampling, Testing, Inspection, and Measurement of Quantities Add the following:

"Minimum sampling and testing FREQUENCY is defined in Table 160.

Sampling and testing by the contractor shall meet the applicable AASHTO and ASTM Standards.”

96 SPS 160-1 (07/12/10)

TABLE 160

SAMPLING, TESTING AND MEASUREMENT REQUIREMENTS

A soil type is defined such that all soil in the represented volume shall have the same group symbol in the Unified Soil Classification system (ASTM D 2487) and the percent passing the No. 4 sieve shall not vary more than 10 percent between samples.

Wherever a AASHTO T99 or T180 moisture density curve is required, gradation data will be provided as shown below. The moisture density sample shall maintain the same percentage of coarse material (passing 50 mm and retained on a number 4 sieve) as in the original field sample. Field density testing of soil will normally require the use of AASHTO T224, Coarse Particle Correction.

Field Sample

Moisture Density Test Material

Percent plus 19 mm

Percent plus No. 4

Percent 19 mm to No. 4 sieve

Percent minus No. 4 sieve

Where random sample or random measurement is specified, it shall be a stratified statistically random sample. Random numbers are to be determined by ASTM D3665 Section 5.1 thru 5.7, or a computer generated random number program approved by the Contracting Officer. The sampling must be stratified to eliminate the possibility of sample points being "clustered". Stratification is calculated by dividing the total quantity for the applicable bid item by the sample FREQUENCY. This process divides the total project quantity of one lot into sublots. The random number is used to obtain a random sampling point within each sublot. The contractor may terminate a lot, and start a new lot when approved by the Contracting Officer. Once a lot is terminated it may not be combined with any other lot. If material within a sublot fails to meet specification requirement, the Contracting Officer may allow the contractor to rework the sublot materials and resample at a different randomly selected location.

Key to symbols used in table:

CT: Sampling and testing by contractor's personnel identified by name on the approved contractor's Q/C plan. Interim approval of personnel submitted will be based on specified training or experience requirements. Final approval will be based on observation of work performance on the project.

PE: Sampling and testing under the direction of and certification by a registered engineer retained by the contractor and specifically identified on the approved contractor's Q/C plan.

FS: Sampling, testing, measuring and/or data to be furnished by the Forest Service.

96 SPS 160-2 (07/12/10)

Note: The minimum FREQUENCY shown in this table is for contractor Quality Control sampling and testing. The contractor can run additional samples over the minimum number specified in the table. These additional samples can be taken in any manner, at any time desired by the contractor. Quality assurance sampling and testing by the Forest Service may be done at any time or location.
