GWJ 106.1 (07/12/2002)

106.03 Delete this subsection and add the following:

Units of

Measurement “Forest Service Specifications for Construction of Roads and Bridges (Revised August 1996) are based on Modern Metric units of measurement. The dimensions and units of measure SHOWN ON THE DRAWINGS and used to develop SPECIAL PROJECT SPECIFICATIONS for this contract, utilize U.S. Standard English units of measure. All measurements referenced in the August 1996 Forest Service Standard Specifications (EM-7720-100) shall be converted to U.S. Standard English units of measure. Appendix A – Engineering Conversion Factors and Appendix B – SI (Modern Metric) Conversion Factors, are included on pages 611 – 614 of the Standard Specification Appendices to assist with any required conversions.

Work required by the contract will be paid based on the PAY UNIT (U.S. Standard English measure) as DESIGNATED IN THE SCHEDULE OF ITEMS.

Under each Specification Section with PAY ITEMS of work DESIGNATED IN THE SCHEDULE OF ITEMS for measurement and payment under this contract, the last subsection “Payment - Basis”, shall have the following format:

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.

(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.

(3) 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 measurement 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.

(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) MFBM. 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 measured 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.

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

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