01270, Measurement and Payment



This master should be used by designers working on Port of Portland construction projects and by designers working for PDX tenants (“Tenants”). Usage notes highlight a few specific editing choices, however the entire section should be evaluated and edited to fit specific project needs.

SECTION 012200 – UNIT PRICES

Spec Writer: If this is an RFP, edit out references to “bid.”

GENERAL

1. INCIDENTAL WORK

A. Consider work not listed, but necessary to complete the work, as incidental. Each bid item has incidental work associated with it. Some of the incidentals are identified. However, the list is not complete. This does not relieve the Contractor from the responsibility for completing the incidental work. Incidental work includes, but is not limited to, project meetings and seminars, compacting, grading, hauling, mixing, placing, shaping, and watering, as specified.

2. WEIGHING, WEIGH AND TRUCK MEASURE DELIVERY TICKETS

A. A ton is 2,000 pounds. Measure and compute weight to the nearest one-tenth (0.1) of a ton.

B. Weigh on certified public or private scales. The scales shall be of a capacity, kind, size and type suitable for the weighing to be done. Scales shall be tested, sealed, and certified by an acceptable certifying authority. The Port may order recertification of scales to ensure accuracy. Recertification shall be at no added cost to the Port.

C. Within one day after delivery, submit a weight delivery ticket to the inspector for each load. Payment will only be made for material accounted for on a delivery ticket. Delivery tickets shall state project name, product delivered, date and time weighed, name and signature of the weigh master, and name of the truck driver.

D. Where items are paid by truck measure, each haul unit shall be measured by the Port and the Contractor jointly to determine the truck volume. Give each haul unit a unique number which is clearly shown on the unit. Submit a delivery ticket to the inspector for each load. Payment will only be made for material accounted for on a delivery ticket. Delivery tickets shall state project name, product delivered, haul unit number, date and time of delivery, and the driver’s name and signature. Heap loads to the satisfaction of the inspector to assure that delivered volume is equal to the truck volume as measured by the Port and the Contractor.

Use E for barge measure only.

E. Weights of material delivered by barge shall be determined by draft of the loaded and empty barge. Furnish tables or hydrostatic curves for each barge used, established by a certified marine surveyor, from which weights may be calculated. Draft measurements will be taken by the Port.

Use 1.3 and 1.4 for hot-mix asphalt concrete (HMAC) bid items as applicable.

3. STATISTICAL ANALYSIS

A. The Port will divide the materials into lots and sublots, randomly sample and test them as required, and analyze the results statistically to determine whether the materials conform to the specifications.

B. All acceptance test results of lots and sublots will be analyzed collectively using the quality level analysis procedure described below. This procedure shall not be used for a lot with less than three sublots. Sampling of material for a lot that contains two or fewer sublots shall be increased to obtain at least three sublots. The Port has discretion to either accept or reject lots originating with two or fewer sublots, even after sampling is increased.

1. Lot: See definition in Section 321200.

2. Sublot: A sublot is a portion of a lot as defined in Section 321200.

3. Quality Level Analysis: Quality level analysis is a statistical procedure to determine, for each lot:

a. The percentage of each constituent of the materials meeting the specifications;

b. The pay factor for each constituent; and

c. The composite pay factor, when specified.

4. Pay Factor and Composite Pay Factor Computation: Procedures for determining the percent meeting the specifications, pay factors, and composite pay factor for a lot are as follows:

a. Compute lot arithmetic mean ([pic]) for each constituent:

|[pic] |Where ΣX = summation of sample test values, and |

| |n = total number of samples |

b. Compute standard deviation (sd) for each constituent:

|[pic] |Where ΣX2 = summation of the squares of each sample test value |

| |[pic] = square of the lot arithmetic mean |

| | |

c. Compute the upper quality index (QU) for each constituent:

|[pic] |Where upper specification limit (USL) is the target value plus allowable |

| |tolerance |

| | |

d. Compute the lower quality index (QL) for each constituent:

|[pic] |Where lower specification limit (LSL) is the target value minus allowable |

| |tolerance |

| | |

e. From Table 1, for each constituent, determine the percent within the upper specification limit (PU) which corresponds to a given QU. If USL is 100 percent or is not specified, PU will be 100.

f. From Table 1, for each constituent, determine the percent within the lower specification limit (PL) which corresponds to a given QL. If LSL is 0 or not specified, PL will be 100.

g. Compute the quality level, or total percent within specification limits (PT), for each constituent:

1) PT = (PU + PL) - 100

h. Using the PT above, determine the pay pactor (PF) from Table 2 for each constituent tested. A minimum PF of 1.00 will be used when all sublot test values are within the upper and lower specification limits, regardless of the calculated PF.

i. Compute the weighted pay factor (WPF) for each constituent:

|WPF = (PF) x (fi) |Where fi = weighting factor listed in the specifications for each constituent |

| |tested. |

| | |

j. Compute the composite pay factor (CPF) for the lot and report the results to three decimal places.

|[pic] |Where Σ WPF = sum of the weighted pay factors for each constituent |

| |Σ fi = sum of the weighting factors listed in the specifications. |

4. STATISTICAL ACCEPTANCE SAMPLING AND TESTING

A. The Contractor shall sample and test materials for acceptance, as required by the contract documents. The Contractor may statistically evaluate test results for purposes of quality control or to predict a PF or CPF. The following apply:

1. Statistical Acceptance: The Port will perform statistical analysis in accordance with these specifications for acceptance and to determine a PF or CPF. The Port’s determination of the PF or CPF shall be controlling.

2. Pay Adjustments: As an incentive to produce quality materials, the Port’s acceptance will be based upon the following:

a. Specification Materials: Any constituent with a PF of 1.00 or greater, or any materials with a CPF of 1.0000 or greater, will be considered specification materials. A constituent with a PF greater than 1.00 or materials with a CPF greater than 1.0000 will be considered of superior quality and, when specified, may earn a PF adjustment greater than 1.00, up to a maximum of 1.05.

b. Nonspecification Materials: Any constituent with a PF less than 1.00, or any materials with a CPF less than 1.0000 will be considered nonspecification materials. When specified, a lot containing nonspecification materials may be accepted at a reduced price as described below.

3. Nonspecification Materials:

a. Lot-in-Progress: The Contractor shall shut down production when any of the following occurs:

1) The CPF for a lot-in-progress drops below 1.0000 and the Contractor is taking no corrective action;

2) The CPF is less than 0.7500; or

3) Any constituent test is continually out of specification limits, regardless of whether or not the CPF is below 0.7500.

b. The Contractor shall not resume production until the Port has determined that specification materials can be produced, and has given approval to resume.

1) For a lot with a CPF between 0.7500 and 1.0000, the Port will take one of the following actions:

a) Remain in Place: Allow materials to remain in place with an appropriate price reduction.

b) Corrective Work: Require corrective work, at the Contractor’s expense, with an appropriate price reduction.

2) For a lot with a CPF below 0.7500, the Port will take one or more of the following actions:

a) Remain in Place: Allow materials to remain in place with an appropriate price reduction that may range from 25 percent to 100 percent (no payment).

b) Corrective Work: Require corrective work, at the Contractor’s expense, with an appropriate price reduction that may range from zero (full payment) to 100 percent (no payment).

c) Remove and Replace: Require complete removal and replacement with specification materials. No payment will be made for the rejected materials, the cost of removal, or for the costs of sampling and testing.

Use only for long-duration projects with the consent of the PE/PM.

5. ASPHALT CEMENT AND FUEL PRICE ADJUSTMENTS

A. An escalation/de-escalation clause for price adjustments of asphalt cement and major fuel usage (over 100 gallons) will be in effect during the life of the contract. A monthly price adjustment (plus or minus) will be made for bid items containing asphalt cement and for fuel used in the production of a product or to haul or place materials for this contract.

B. Price adjustments will be determined in the following manner:

1. A Monthly Asphalt Cement Material Price (MACMP) established by the Oregon Department of Transportation (ODOT) will be used each month to adjust the cost of materials containing asphalt cement. If this index ceases to be available for any reason, the Port may select and use a substitute price source or index to establish the MACMP each month. The base price for asphalt cement shall be the MACMP published by ODOT at the beginning of the month in which the bid opening occurs.

2. A Monthly Fuel Price (MFP) will be established each month. The MFP for a given month will be the average weekly price obtained from the Oil Price Information Service (OPIS) weekly listing dated the first Monday of that month for No. 2 diesel fuel for Portland, OR. Price will be based solely on rack and resellers’ prices exclusive of freight, taxes, and special discounts. If the average weekly price is not posted by OPIS or is otherwise not available for the first Monday of the month, the Port may use the average weekly price posted immediately before or after the first Monday. If the average weekly prices cease to be available from OPIS for any reason, the Port may select and use a substitute price source or index to establish the MFP each month. The base price for diesel fuel shall be the MFP established for the month in which the bid opening occurs.

3. The Monthly Adjustment Factor (MAF) for the MACMP or MFP will be determined each month as follows:

a. If the MACMP or MFP is within 10 percent of the base, there will be no adjustment.

b. If the MACMP or MFP is more than 110 percent of the base, then:

1) MAF = (MACMP or MFP) – (1.10 x base)

c. If the MACMP or MFP is less than 90 percent of the base, then:

1) MAF = (MACMP or MFP) – (0.90 x base)

6. BID ITEMS

A. Payment constitutes total compensation for furnishing materials; for preparation of these materials; and for labor, equipment, tools and incidentals necessary to complete the work as specified and shown on the drawings. Measurement will not include unauthorized work performed beyond the design limits. Replace material removed without authorization at no added cost to the Port. The method of measurement and the basis of payment for bid items will be as follows.

• Insert the type(s) of HMAC (1-inch dense, 3/4-inch dense, 1/2-inch dense, 3/8-inch dense, 3/4-inch open, 1/2-inch open, 3/4-inch ATPB) in the second blank.

• Insert the words “in Leveling,” “in Temporary,” or “in Leveling and Temporary” in the third blank as applicable.

88. Level _____, _____ HMAC _____ – TON

A. The accepted quantities of hot-mix asphalt concrete (HMAC) will be measured by the ton. No deduction will be made for lime or any other additive used in the mixture.

BH. When reclaimed asphalt pavement (RAP) materials are used, measurement of the total asphalt quantity will be based on quality control tests averaged to the nearest 0.01 percent.

BI. Payment will be payment in full for furnishing and placing the materials and for providing all equipment, labor, and incidentals necessary to complete the work as specified.

Fill in specific gravity used for quantity calculation in blank below.

BJ. The estimated unit price quantities of HMAC were computed on the basis of aggregates having a specific gravity of _____. No price adjustments will be made for actual specific gravities.

BK. Unless otherwise indicated, no separate or additional payment will be made for the following:

1. Reconditioning existing roadway.

2. Leveling work.

3. Lime.

4. Quality control testing.

5. Anti-stripping additives.

Use on projects with pay factors. Define acceptable and corrective action options based on Articles 1.3 and 1.4 of this section.

BL. HMAC Price Adjustments: The composite pay factor (CPF), calculated according to these specifications, will be applied to the contract unit price for this bid item and to the applicable lot quantities. The CPF will be made available to the Contractor within 24 hours of receipt of the required quality control test results. If less than three samples are tested, the CPF will be computed as outlined in Section 321200 and this section. The maximum CPF for material represented by less than three samples will be 1.0.

BM. To accommodate the definition for “lot” in Section 321200, interpret the upper specification limit (USL) and the lower specification limit (LSL) to allow adjustments to a job mix formula (JMF) according to Section 321200 without changing lots. Include all material from the original JMF and revisions of that JMF in the statistical analysis unless a change in the lot is required by Section 321200. If JMF target values are modified according to Section 321200, the CPF will be calculated in the following manner:

1. The adjusted target value will be evaluated as zero with the USL and LSL representing the allowable tolerances of Section 321200. All sample test values for the changed constituents will be compared to the target for each sublot. The differences between the target values and sample test values are the adjusted sample test values for each sublot. These will be analyzed for determination of the pay factor (PF) for the constituent.

2. The PF for compaction will be:

|Type/Method |PF |Maximum PF |

|Normal Pavement | | |

| Control Strip Method |-- |1.00 |

| MAMD Method |-- |1.05 |

|Thin Pavement |1.00 |-- |

|Other Areas |1.00 |-- |

3. Use the following table to determine price adjustments in the CPF for constituents of HMAC:

|Gradation Constituents |Dense-Graded HMAC Type |

| |Weighting Factor (f) |

|All Aggregate Passing |1" |3/4" |1/2" |3/8" |

|1 1/2" |1 | | | |

|1" |1 |1 | | |

|3/4" |1 |1 |1 | |

|1/2" |1 |1 |1 |1 |

|3/8" |-- |-- |-- |1 |

|No. 4 |5 |5 |5 |5 |

|No. 8 |5 |5 |6 |6 |

|No. 30 |2 |3 |3 |3 |

|No. 200 |10 |10 |10 |10 |

|Other Constituents |

|Asphalt Content |26 |26 |26 |26 |

|Moisture Content |8 |8 |8 |8 |

|Compaction |40 |40 |40 |40 |

a. Those HMAC constituents statistically evaluated will be eligible for a maximum PF of 1.05 (see), unless otherwise specified.

b. When the CPF is greater than 1.000 for material used in leveling courses for HMAC, it will be reduced as follows:

1) Reduction in CPF = (CPF-1) x 0.5

c. If these specifications do not require measurement of a constituent, its individual PF will be considered 1.00 in calculating the CPF as follows:

1) A price adjustment will be determined by the following formulas:

|(CPF - 1) x [(JMF% ( 100 x Asphalt Unit Price) + (HMAC Unit Price)] x (LQ) = ____ |

| |

|Where JMF% is the asphalt cement percent from the JMF and LQ is the quantity of mixture in the lot. |

| |
