quantify the amount and certify the amount if required by FAR Clause 52.233-1 Disputes (Alternate I).

Include an explanation of the interpretation of contract terms, the contract clause under which the claim is made, supporting documentation, and adequate cost data to support the amount claimed.

103.03 Value Engineering. Follow the requirements of FAR Clause 52.248-3 Value Engineering - Construction.

Before undertaking significant expenditures, submit a written description of the value engineering change proposal (VECP) concept. Within 14 days the CO will inform the Contractor as to whether the concept appears to be viable or if the concept is unacceptable. If the CO indicates that the concept appears to be viable, prepare and submit the formal VECP proposal.

103.04 Contractor Records. Upon request, provide records related to the contract to the Government for up to 3 years after final payment or for longer periods as provided by law.

Include a provision in subcontracts at all tiers giving the Government the same rights as provided above with respect to the subcontractor's records.

103.05 Partnering. To facilitate this contract, the CO offers to participate in a formal partnership with the Contractor. This partnership draws on the strengths of each organization to identify and achieve reciprocal goals. Partnering strives to resolve problems in a timely, professional, and non-adversarial manner. If problems result in disputes, partnering encourages, but does not require, alternative dispute resolution instead of the formal claim process. The objective is effective and efficient contract performance to achieve a quality project within budget and on schedule.

Acceptance of this partnering offer by the Contractor is optional, and the partnership is bilateral.

If the partnering offer is accepted, mutually agree with the CO on the level of organizational involvement and the need for a professional to facilitate the partnering process. Engage the facilitator and other resources for key Contractor representatives and the CO to attend a partnership development and team-building workshop usually between the time of award and the Notice to Proceed. Hold additional progress meetings upon mutual agreement.

The direct cost of partnering facilities, professional facilitation, copying fees, and other miscellaneous costs directly related to partnering meetings will be shared by the Contractor and Government. Secure and pay for facilities, professional fees, and miscellaneous requirements. Submit invoices to the CO. The Government will reimburse the Contractor for 50 percent of the agreed costs incurred for the partnering process. The Government’s share will not exceed $5,000.

Each party is responsible for making and paying for its own travel, lodging, and meal arrangements. No time extension for the completion of the project will be made for the use of partnering.

Section 109. — MEASUREMENT AND PAYMENT

109.01 Measurement of Work. Take and record measurements and perform calculations to determine pay quantities for invoicing for work performed. Take or convert measurements of work according to U.S. Customary (Metric) measure.

Unless otherwise specified, measure when the work is in-place and complete according to the contract.

Measure the actual work performed, except do not measure work outside the design limits or other adjusted or specified limits (staked limits). Measure structures to the lines according to the plans or to approved lines adjusted to fit field conditions.

Take measurements as described in Subsection 109.02 unless otherwise modified by the Measurement Subsection of the Section controlling the work being performed. Measurement of quantities for payment for the individual pay items will be based on the contract price for each pay item according to Table 109- 1.

Table 109-1 Decimal Accuracy of Quantities for Payment

Contract Price

Decimal Accuracy of Quantities for Payment

< $1.00 0 decimal ≥ $1.00 to < $100.00 1 decimal

≥ $100.00 to < $1000.00 2 decimals ≥ $1000.00 3 decimals

Decimal precision for measurement is one decimal beyond accuracy of quantities for payment.

Remeasure quantities if it has been determined that a portion of the work is acceptable, but has not been completed to the lines, grades, and dimensions shown in the plans or established by the CO.

Submit measurement notes within 24 hours of completing work that is in-place and complete according to the contract. For on-going work, submit measurement notes daily. When work is not complete, identify the measurement as being an interim measurement. Submit the final measurement when the installation is completed. Measurement notes form the basis of the Government’s receiving report; see Subsection 109.08(d). For lump sum pay items, submit documentation to support invoiced progress payment on a monthly basis.

Use an acceptable format for measurement records. As a minimum, include the following information:

(a) Project number and name;

(b) Pay item number and description;

(c) Date the work was performed;

(d) Location of the work;

(e) Measured quantity;

(f) Calculations made to arrive at the quantity;

(g) Supporting sketches and details as needed to clearly define the work performed and the quantity measured;

(h) Names of persons measuring the work;

(i) Identification as to whether the measurement is interim or final; and

(j) Signed certification statement by the persons taking the measurements and performing the calculations, that the measurements and calculations are correct.

109.02 Measurement Terms and Definitions. Unless otherwise specified, the following terms are defined as follows:

(a) Acre (Hectare). 43,560 square feet (10,000 square meters). Make longitudinal and transverse measurements for area computations horizontally. Do not make deductions from the area computation for individual fixtures having an area of 500 square feet (50 square meters) or less.

(b) Contract quantity. The quantity to be paid is the quantity listed in the bid schedule. The contract 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 contract 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.

(c) Cubic yard (Cubic meter).

(1) Cubic yard (Cubic meter) in-place. Measure solid volumes by a method approved by the CO or by the average end area method as follows:

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

CO;

(b) If a 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. Use the remeasurements to calculate new end areas; and

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

(2) Cubic yard (Cubic meter) in the hauling vehicle. Measure the cubic yard (cubic meter) 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 (cubic meters) for payment purposes if the conversion factors are mutually agreed to in writing.

(3) Cubic yard (Cubic meter) in the structure. Measure according to the lines of the structure as shown in the plans, except as altered by the CO to fit field conditions. Make no deduction for the volume occupied by reinforcing steel, anchors, weep holes, piling, or pipes less than 8 inches (200 millimeters) in diameter.

(4) Cubic yard (Cubic meter) by metering. Use an approved metering system.

(d) Day. A calendar day beginning and ending at midnight. Round portions of a day up to the full day.

(e) Each. One entire unit. Measure the actual number of units completed and accepted.

(f) Gallon (Liter). The quantity may be measured by the following methods:

(1) Measured volume container.

(2) Metered volume. Use an approved metering system.

(3) Commercially-packaged volumes.

(4) Measured by mass. Use an approved weighing device.

When asphalt material is measured by the gallon (liter), measure the volume at 60 °F (15 °C) or correct the volume to 60 °F (15 °C) using recognized standard correction factors.

(g) Hour. 60 minutes. Measure the actual number of hours ordered by the CO and performed by the Contractor. Round portions of an hour up to the next half hour. Measure time in excess of 40 hours per week at the same rate as the first 40 hours.

(h) Linear foot (Meter). 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.

(i) 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 pay item. The quantity is designated as "All". Estimated quantities of lump sum work shown in the contract are approximate.

(j) M-gallon. 1,000 gallons. Measure according to Subsection 109.02(f).

(k) Mile (Kilometer). 5,280 linear feet (1000 meters). Measure horizontally along the centerline of each roadway, approach road, or ramp.

(l) Month. A month as defined by the Gregorian calendar. Measure portions of a month by prorating based on the total days worked.

(m) Pound (Kilogram). Measure according to Subsection 109.03. If sacked or packaged material is furnished, the net weight as packed by the manufacturer may be used.

(n) Slurry unit. Approximately 1,000 gallons (4000 liters) of water plus the specified material. Four (ten) slurry units contain material to cover one acre (hectare). Measure according to Subsection 109.02(f).

(o) Square foot and Square yard (Square meter). 1 square yard equals 9 square feet. Measurements for area computations will be made horizontally or vertically to the surface being measured. No deductions from the area computation will be made for individual fixtures having area of 9 square feet (1 square meter) or less.

(p) Thousand board feet measure, MFBM. 1000 board feet. Measurement equal to 1,000 feet of wood that is 12 inches wide and 1 inch thick.

(q) Ton (Metric ton). 2,000 pounds avoirdupois (1000 kilograms). Measure according to Subsection 109.03.

No adjustment in a contract price will be made for variations in quantity due to differences in the specific gravity or moisture content.

Use net-certified scale masses or masses based on certified volumes in the case of rail shipments as a basis of measurement subject to correction when asphalt material is lost from the car or the distributor, wasted, or otherwise not incorporated in the work. When asphalt material is shipped by truck or transport, net-certified masses, subject to correction for loss or foaming, may be used for computing quantities.

When emulsified asphalt is converted from volume to mass, use a factor of 240 gallons per ton (1000 liters per metric ton) regardless of temperature.

When asphalt binder for asphalt concrete pavement is stored in tanks devoted exclusively to the project, base quantities on invoices. When asphalt binder for asphalt concrete pavement is not stored in tanks devoted exclusively to the project or when the validity of the quantity requested for payment is in question; base quantities on the asphalt content determined by testing.

(r) Week. A 7 day period beginning and ending at the same designated time. Measure portions of a week by prorating based on the total days worked.

109.03 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; 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, submit a supplier's invoice with net mass or volume converted to mass. Periodic check weighing may be required.

(c) Project weighing system. Furnish, erect, and maintain acceptable automatic digital scales. Provide scales that record mass at least to the nearest 100 pounds (50 kilograms). Maintain the scale accuracy to within 0.5 percent of the correct mass throughout the range of use.

Do not use spring balances.

Install and maintain platform scales with the platform level with rigid bulkheads at each end. Make the platform of sufficient length to permit simultaneous weighing of all axle loads of the hauling vehicle. Coupled vehicles may be weighed separately or together according to Subsection 2.20, paragraph UR.3.3, Single-Draft Vehicle Weighing of NIST Handbook 44, Specifications, Tolerances, and Other Technical Requirements for Weighing and Measuring Devices.

Install and maintain belt-conveyor scales according to Subsection 2.21, Belt-Conveyor Scale Systems of NIST Handbook 44.

Before production on the project, after relocation, and at least once per year; have the weighing portion of the system checked and certified by the State Bureau of Weights and Measures or a private scale service certified by the Bureau of Weights and Measures. Seal the system to prevent tampering or other adjustment after certification.

Attach an automatic printer to the scale that is programmed or otherwise equipped to prevent manual override of all mass information. For weighed pay quantities, program the printer to provide the following information for each weighing:

(1) Project number and name;

(2) Pay item number and description;

(3) Date;

(4) Time;

(5) Ticket number;

(6) Haul unit number;

(7) Net mass in load at least to the nearest 100 pounds (50 kilograms);

(8) Subtotal net mass for each haul unit since the beginning of the shift; and

(9) Accumulated total net mass for all haul units since the beginning of the shift.

If a printer malfunctions or breaks down, the Contractor may manually weigh and record masses for up to 48 hours provided the method of weighing meets other contract requirements.

Furnish competent scale operators to operate the system.

When platform scales are used, weigh empty haul units at least twice per day.

Use an approved format for the mass records. Submit the original records and a written certification as to the accuracy of the masses at the end of each shift.

109.04 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 as applicable:

(a) Project number and name;

(b) 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 records. Submit the original records and a written certification of the delivery of the material at the end of each shift.

109.05 Scope of Payment. Payment for contract work is provided, either directly or indirectly, under the pay items listed in the bid schedule.

(a) Direct payment. Payment is provided directly under a pay item listed in the bid schedule when one of the following applies:

(1) The work is measured in the Measurement Subsection of the Section ordering the work and the bid schedule contains a pay item for the work from the Section ordering the work.

(2) The Measurement Subsection of the Section ordering the work, references another Section for measuring the work and the bid schedule contains a pay item for the work from the referenced Section.

(b) Indirect payment. Work for which direct payment is not provided is a subsidiary obligation of the Contractor. Payment for such work is indirectly included under other pay items listed in the bid schedule. This includes instances when the Section ordering the work references another Section for performing the work and the work is not referenced in the Measurement Subsection of the Section ordering the work.

Compensation provided by the pay items included in the bid schedule is full payment for performing contract work in a complete and acceptable manner. Risk, loss, damage, or expense arising out of the nature or prosecution of the work is included in the compensation provided by the pay items.

Work measured and paid for under one pay item will not be paid for under other pay items.

The quantities listed in the bid schedule are approximate unless designated as a contract quantity. Limit pay quantities to the quantities staked, ordered, or otherwise authorized before performing the work.

Payment will be made for the actual quantities of work performed and accepted or material furnished according to the contract. No payment will be made for work performed in excess of that staked, ordered, or otherwise authorized.

109.06 Pricing of Adjustments. Determine costs according to FAR Part 31 Contract Cost Principles and Procedures. Follow the requirements of FAR clauses providing for an equitable price adjustment.

If agreement on price and time cannot be reached, the CO may make a unilateral determination.

Submit cost or pricing data, as defined in FAR Subpart 2.1—Definitions, for the Contractor and each major subcontractor.

Submit with the cost or pricing data a written proposal for pricing the work according to Subsection 109.06(a)(1). See FAR Subpart 15.4—Contract Pricing and FAR Table 15-2— Instructions for Submitting Cost/Price Proposals when Certified Cost or Pricing Data are Required for guidance.

Certify cost or pricing data according to FAR Subpart 15.4, upon completion of negotiations.

(b) Post-work pricing. When a contract modification is not forward priced, it requires a change order and a supplemental agreement reflecting the resulting equitable adjustment. When negotiating the price of a contract modification after all or most of the work has been performed, submit the following:

(1) Direct costs.

(a) Material. Include invoices showing the cost of material delivered to the work.

(b) Labor. Show basic hourly wage rates, fringe benefits, applicable payroll costs (that is FICA, FUTA, worker's compensation, insurance, and tax levies), paid subsistence, and travel costs for each labor classification and foreman employed in the adjusted work.

(c) Equipment. Include a complete descriptive listing of equipment including make, model, and year of manufacture.
