MEASUREMENT AND PAYMENT

Measurement of Work Methods of Measurement One of the following methods of measurement for determining final payment is DESIGNATED IN THE SCHEDULE OF ITEMS for each PAY ITEM (Section 01201):

a) Actual Quantities (AQ).

b) Design Quantities (DQ).

c) Lump Sum Quantities (LSQ).

Measurement Terms and Definitions

1. Acre (AC). 43,560 square feet. Make longitudinal and transverse measurements for area computations horizontally unless specified on the ground surface. Do not make deductions from the area computation for individual fixtures having an area of 500 square feet or less.

2. Actual Quantities (AQ). These quantities are determined from measurements of completed work.

3. Design quantity (DQ). The quantity to be paid is the quantity shown in the bid schedule. The design quantity will be adjusted for authorized changes that affect the quantity or for errors made in computing this quantity. If there is evidence that a quantity specified as a design quantity is incorrect, submit calculations, drawings, or other evidence indicating why the quantity is in error and request, in writing, that the quantity be adjusted. Design quantities will be adjusted only when there are errors in the original design of 15% or more. Changes in the number of units DESIGNATED IN THE SCHEDULE OF ITEMS may be authorized under any of the following conditions:

a) Changes in the work authorized by the Contracting Officer.

b) A determination by the Contracting Officer that errors exist in the original design that cause a PAY ITEM quantity to change by 15 percent or more.

c) A written request submitted to the Contracting Officer showing evidence of errors in the original design that cause the 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.

4. Cubic yard (CY).

a) Cubic yard in place. Measure solid volumes by a method approved by the Contracting Officer or by the average end area method as follows:

(a) Take cross-sections of the original ground and use with design or staked templates or take other comparable measurements to determine the end areas. Do not measure work outside of the established lines or slopes.

(b) If any portion of the work is acceptable but is not completed to the established lines and slopes, retake 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.

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

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 on 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 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 current leveled load volume is 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 purposes if the conversion factors are mutually agreed to in writing.

c) Cubic yard in the structure. Measure according to the lines of the structure as shown on the plans except as altered by the Contracting Officer to fit field conditions. Make no deduction for the volume occupied by reinforcing steel, anchors, weep holes, piling, or pipes less than 8 inches in diameter.

d) Cubic yard by metering. Use an approved metering system.

5. Each (EA). One entire unit. The quantity is the actual number of units completed and accepted.

6. Hour. Measure the actual number of hours ordered by the Contracting Officer and performed by the contractor.

7. Linear foot. As applicable, measure the work along its length from end-to-end; parallel to the base or foundation; along the top; along the front face; or along the invert. Do not measure overlaps.

8. Mile. 5,280 linear feet. Measure horizontally along the centerline of each roadway, approach road, or ramp.

9. Lump sum quantity (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. Do not measure directly. The bid amount is complete payment for all work described.

10. Station. 100 linear feet. Measure horizontally along centerline or reference line of each roadway, approach road, or ramp.

Weighing Procedures and Devices

Batch masses may be acceptable for determination of pay quantities when an approved automatic weighing, cycling, and monitoring system is included as part of the batching equipment.

When a weighing device is determined to indicate less than true mass, no additional payment will be made for material previously weighed and recorded. When a weighing device is determined to indicate more than true mass, all material received after the last previously correct weighing accuracy test will be reduced by the percentage of error in excess of 0.5 percent.

When material is proportioned or measured and paid for by mass, provide one of the following:

(a) Commercial weighing system. Use permanently-installed and certified commercial scales.

(b) Invoices. If bulk material is shipped by truck or rail and is not passed through a mixing plant, furnish a supplier's invoice with net mass or volume converted to mass. Periodic check weighing may be required.

Receiving Procedures

When the method of measurement requires weighing or volume measurement in the hauling vehicle, furnish a person to direct the spreading and distribution of material and to record the location and placement of the material on the project. During the placement, maintain a record of each delivery and document it in an acceptable manner. Include the following information as applicable:

(a) Project identification;

(b) Contract pay item number and description;

(c) Location where placed;

(d) Date;

(e) Load number;

(f) Truck identification;

(g) Time of arrival;

(h) Mass or volume; and

(i) Spread person's signature.

Use an approved format for the delivery record(s). Furnish the original record(s) and a written certification of the delivery of the material at the end of each shift.

Subsequent move-ins of equipment shall be treated the same as the initial move-in and will require notification.

2. All equipment shall be washed prior to mobilization to the Forest to minimize the introduction of foreign materials and fluids to the project site. All equipment shall be free of oil, hydraulic fluid, and diesel fuel leaks. To prevent invasion of noxious weeds or the spread of whirling disease spores, all equipment shall be power washed or cleaned to remove all dirt, plant parts and material prior to mobilization. Truck beds and dump boxes hauling to the project site shall also be cleaned prior to entering the Forest. It will be the contractor's responsibility to insure that adequate measures have been taken. Equipment shall be inspected by the Inspector prior to mobilizing to the Forest. Only construction equipment inspected by the Nez Perce Tribe or Forest Service will be allowed to operate within the project area.

3. Equipment shall be in a well-maintained condition to minimize the likelihood of a fluid leak. Any leaks or accumulations of grease would be corrected before entering the project area. If a fluid leak does occur, the project Inspector and COR shall be notified immediately, and all work ceased until the leak has been rectified. At all times during the construction phase, fluid spill containment equipment adequately sized for specific quantities of fuel shall be present on-site and ready for deployment should an accidental spill occur. Fuel spill kit shall include an oil-absorbing floating boom and absorbent pads. Contractor and Contractor’s representatives shall be knowledgeable on use of the spill containment equipment. The Contracting Officer reserves the right to refuse equipment that does not meet criteria.

4. Equipment that will be used in live water shall utilize hydraulic fluid that is non-toxic to salmonids. The following criteria should be met to determine if a hydraulic fluid is nontoxic to salmonids during acute exposure: (a) The test species used should be a salmonid (most often this will be rainbow trout, but occasionally Chinook salmon or coho salmon are tested); (b) The test duration should be 96 hours; (c) The test should be conducted using the water accommodated fraction (WAF) (the WAF is used in testing hydrophobic materials to provide a "worst case scenario" for exposure to aquatic organisms); and (d) The value of the LC50 should be >1000 mg/L. Several products on the market meet these specifications.

According to the guidance provided by the National Oceanic and Atmospheric Administration, the following products meet the required criteria:

There is the potential to find old mining refuse such as cables, culverts, and small garbage. This becomes the property of the Contractor and shall be removed from the site.

b) The Contractor may provide temporary restroom and cleanup facilities for Contractor’s employees and shall keep these areas clear of all refuse, rubbish, and debris that may accumulate from any source and shall keep them in a neat condition to the satisfaction of the Contracting Officer.

c) In the event that waste material, refuse, debris, and/or rubbish are not removed from the work by the Contractor, the Contracting Officer reserves the right to have the waste material, refuse, debris, and/or rubbish removed and the expense of the removal and disposal charged to the Contractor.

AIR POLLUTION CONTROL

The Contractor shall not discharge smoke, dust, and other contaminants into the atmosphere that violate the air pollution regulations for the area. The Contractor shall maintain construction vehicles and equipment in good repair. Exhaust emissions that are determined to be excessive by the Contracting Officer shall be repaired or replaced. If determined to be necessary by the Project Inspector, Contractor shall provide a water truck to manage project area dust.

NOISE CONTROL

The Contractor shall comply with all local controls and noise level rules, regulations, and ordinances which apply to any work performed pursuant to the Contract. If the requirements of this Section are more restrictive than those of the local regulations, the requirements of this Section shall govern.

Each internal combustion engine, used for any purpose related to this Contract, shall be enclosed and be equipped with a muffler of a type recommended by the manufacturer. No internal combustion engine shall be operated on the project without said muffler and enclosure.

STORMWATER AND EROSION CONTROL

1. A Stormwater Pollution Prevention Plan (SWPP) for construction activities has been prepared by the Forest Service. The Contractor shall submit for approval by the Contracting Officer updates and particular details to the Government’s SWPP 20 days prior to mobilizing to the site. Once the SWPP modifications are approved, the Contractor shall file for coverage under EPA's Construction General Permit using the “eNOI” system at least 14 calendar days prior to commencing earth-disturbing activities. Refer to http://water.epa.gov/polwaste/npdes/stormwater/EPA-Construction-General-Permit.cfm. The Contractor shall keep the SWPP on site; publicly post notice of permit coverage at the site; and shall follow all appropriate measures to implement the SWPP including:

a. Practices to prevent erosion and sedimentation associated with access roads, stream crossings, construction sites, borrow pit operations, haul roads, equipment and material storage sites, fueling operations and staging areas.

b. A spill containment and control plan with notification procedures, specific clean up and disposal instructions for different products, quick response containment and clean up measures that will be available on the site, proposed methods for disposal of spilled materials, and employee training for spill containment. A list of potential contaminants on the project site will be provided in the SWPP.

c. Practices to prevent construction debris from dropping into any stream or water body, and to remove any material that does drop with a minimum disturbance to the streambed and water quality.

2. Erosion control measures shall be in place prior to breaking ground. During construction, all erosion controls shall be inspected by the contractor daily to ensure they are working adequately.

a. If inspection shows that the erosion controls are ineffective, work crews will be mobilized immediately to make repairs, install replacements, or install additional controls as necessary.

b. Sediment must be removed from erosion controls once it has reached 1/3 of the exposed height of the control.

3. The Contractor shall not perform any excavation or earthwork of any type on the project until a written acceptance of the “Dewatering and Work Area Isolation Plan” and SWPP has been received and approved from the Contracting Officer and erosion control devices are on site. If in the opinion of the Contracting Officer, the plan does not sufficiently address the objectives (Section 02140); the Contractor shall revise the plan accordingly to the satisfaction of the Contracting Officer.

4. Contractor shall provide measures to prevent movement of soil into waterways or wetlands, e.g. filter bags, sediment traps or catch basins, vegetative strips, berms, jersey barriers, fiber blankets, bonded fiber matrices, geotextiles, mulches or compost, wattles and sediment fences, unless approved by the inspector.

a. Turbidity monitoring including personnel and equipment will be provided by the Forest Service.

b. If turbidity levels approach 50 NTUs over background levels 300 feet downstream of the point of discharge, the Contractor shall take measures to reduce turbidity before continuing.

5. Contractor shall provide measures to prevent stockpile erosion during rain events or when the stockpile site is not moved or reshaped for more than 48 hours, by surrounding piles with compost berms, covering piles with impervious materials or other equally effective methods.

6. Contractor shall provide measures to prevent construction vehicles from tracking sediment offsite or onto roadways where it is subject to washing into storm drains, waterways, or wetlands; including gravel access pads, wheel wash stations, or other equally effective methods.

7. Contractor shall not cross live water with heavy equipment.

MERCURY

If elemental mercury is found during project work, Contractor shall stop work in the immediate vicinity and make every reasonable effort to contain the material in such a manner that it will not reach surface or groundwater. The Contractor will contact the COR immediately.

SUBMITTALS

The Contractor shall submit for approval by the Contracting Officer updates and particular details to the Government prepared Stormwater Pollution Prevention Plan (SWPPP) as described in Section 01560.

Before starting work on the project, the Contractor shall submit, for acceptance by the Contracting Officer, a “Dewatering and Work Area Isolation Plan” that conforms to the provided…
