Section 109. — MEASUREMENT AND PAYMENT

109.06 Pricing of Adjustments. Add the following:

ASPHALT CEMENT PRICE ADJUSTMENT PROVISION

GENERAL The Asphalt Cement Price Adjustment Provision provides for a price adjustment in the form of a payment to the Contractor or a rebate to the Government for fluctuations in the cost of asphalt cement used in the performance of applicable construction work. The price adjustment provisions are applicable only to the asphalt cement, as defined in Subsection 702.01, and incorporated in the following eligible contract pay items:

• 40101 Superpave pavement

The price adjustment provisions are also applicable when the Government adds extra work to the eligible pay items already existing under the Contract.

The provision will remain in effect throughout the duration of the contract. Enactment of the Asphalt Cement Price Adjustment Provision will only be considered when the increase or

J-8 decrease in the price of asphalt cement as defined herein exceeds 10 percent.

The Asphalt Cement Price Adjustment Provision is intended to reduce but not eliminate the cost effects of price uncertainty to the Contractor and the Government for asphalt cement used in the construction of this contract. It provides for sharing by the Government in a portion of the Contractor’s risk, which could result from unusual price fluctuations. The provision is not intended to compensate the Contractor for normal day-to-day fluctuations and seasonal changes or to serve as a guarantee of full compensation for asphalt cement price fluctuations.

PRICE INDEXES The Government will generate a monthly performance price index for asphalt cement using price data obtained from Poten and Partners, Inc. (PPI), which publishes a weekly report (Asphalt Weekly Monitor) on high and low selling prices for states in five regions throughout the United States including the East Coast/Northeast, the Mid-Continent/Midwest, the Gulf Coast/Mid South, the Rocky Mountains and the West Coast/Northwest. Weekly high and low selling price data reported for PADD 3/ Pensacola will be averaged and used to establish a base price index, BPI, for this project and a monthly performance price index, MPPI, for the duration of the contract. These indexes are defined as follows:

• BASE PRICE INDEX The base price index, BPI, is the price index determined by the arithmetic average, as specified above, shown in the four weekly publications immediately preceding the bid opening. The BPI will be provided by the Government after contract award. It is as follows:

BASE PRICE INDEX (BPI) FOR ASPHALT CEMENT

PER SHORT TON (TON) (or PER METRIC TON) = $

• MONTHLY PERFORMANCE PRICE INDEX The monthly performance price index, MPPI, is the monthly price index at the time of performance of applicable work as determined by the arithmetic average, as specified above, shown in the four weekly publications issued prior to the last Wednesday of the month (i.e. the monthly performance price index during which asphalt cement is used in the performance of applicable construction work).

PRICE ADJUSTMENTS Price adjustments are calculated by the Government for average conditions and are not intended to reflect the Contractor’s actual purchase price. The ratio of the monthly performance price index and the base price index (MPPI/BPI) is calculated and used to determine price adjustments for eligible pay items as follows:

• No Price Adjustment – When the ratio MPPI/BPI falls within the range of 0.90 to 1.10, no price adjustment will be made for any asphalt cement used in construction work performed during the relevant month.

• Government Rebate – When the ratio MPPI/BPI is calculated to be less than 0.90, the

Government is due a rebate determined in accordance with the following formula:

Government Rebate = [0.90 – (MPPI/BPI)] (BPI) (Q)

J-9

• Contractor Payment – When the ratio MPPI/BPI is calculated to be greater than 1.10, the Contractor is due additional payment determined in accordance with the following formula:

Contractor Payment = [(MPPI/BPI) – 1.10] (BPI) (Q)

The following definitions are applicable to both the Government Rebate and the Contractor Payment formulas:

MPPI = Monthly Performance Price Index for the month during which asphalt cement is used in the performance of applicable construction work.

BPI = Base Price Index that is established immediately preceding the bid opening.

Q = Quantity in tons of asphalt cement for eligible pay items that were used on the project during the progress payment period. The quantity will be calculated using the asphalt content of the approved mix design and the following formula:

Q = Asphalt Concrete Pavement tons placed x (% Asphalt/100)

PRICE ADJUSTMENT COMPENSATION Monthly adjustments will be accrued. The final price adjustment will be paid, or rebated, after completion of all work for eligible pay items. The Contractor may request in writing a partial price adjustment payment once every 12 months, or when the unpaid accrued increase exceeds $10,000. The Government will take a rebate when the deductive accrual exceeds $10,000.

No price adjustments will be made for work performed beyond the Government-approved Contract completion date.

The maximum allowable monthly and final price adjustment to the Contractor or rebate to the Government is limited to a (MPPI/BPI) ratio of 1.6 and 0.4, respectively.

109.08(b). Add the following:

Submit invoices by the 7th day after the closing date. Invoices received after the 16th day following the closing date will not be accepted for payment processing that month. Include late, unprocessed invoice submittals in the following month’s invoice.

154.04. Add the following:

On a weekly basis, submit a copy of all current Contractor test results and pay factor calculations based on those tests for items accepted under Subsection 106.05. When large quantities are produced, calculate pay factors as soon as possible. Use this information to make any necessary adjustments to operations to achieve acceptable pay factors. The Government may use the Contractor's test results to determine final pay factors for acceptance according to Subsection 154.05.

Section 155.—SCHEDULES FOR CONSTRUCTION CONTRACTS

155.02. Add the following after the third paragraph:

155.02A Weather Delays.

(a) Weather Delay Definitions.

(1) Reasonably Predictable Weather. The number of workdays that can expected to be lost in any month due to rainfall based on 10-year historical weather data.

(2) Rain Day. A potentially lost workday on which rainfall is equal to or greater than

0.10 inches

(3) Drying Day. A work day(s) immediately following a rainfall equal to or greater than

1.00 inch which is potentially lost because of wet ground conditions.

(4) Workday. A day not excluded from work by Section 108 of the Special Contract Requirements.

(5) Unusually Severe Weather. When the number of Actual Workdays Lost is greater than the calculated Total Lost Days for the month in question.

(b) Reasonably Predictable Weather. Determine Reasonably Predictable Weather for this contract by completing Table 155-1. Calculate data for Table 155-1 as follows:

(1) Using the last 10 years of historical weather data from the nearest NOAA weather data collection station, compute the average number of workdays lost (rain days plus drying days) for each month and the standard deviation from the average. Add the average number of workdays lost to the standard deviation.

J-12

(2) The Total number of Lost Days (Average Workdays Lost plus 1 Standard Deviation, rounded to whole days) will be considered normal for each month.

(3) Submit a completed Table 155-1 with the initial construction schedule.

(c) Unusually Severe Weather Under FAR Clause 52.249-10, Default (Fixed-Price Construction), the Contractor can request time for a delay due to Unusually Severe Weather.

The number of Actual Workdays Lost is calculated by first totaling the actual Rain Days plus the actual Drying Days occurring in the month in question. From this total, deduct any workdays meeting the following conditions:

(1) The Rain Day or Drying Day occurred on a non-work weekday such as a holiday.

(2) Rainfall occurred at a time when no weather dependent work was in progress or occurred during planned or unplanned shutdowns due to other circumstances such as equipment failure, strikes, material supplies, delays, etc.

(3) The Contractor was still working or able to work on weather dependent activities to the extent that less than 50 percent of the workday was lost due to weather.

If the net number of Actual Workdays Lost is greater than the Total Lost Days, then Unusually Severe Weather occurred during the month in question.

(d) Time Adjustments for Rain Delays. If the net number of Actual Workdays Lost to rain is less than the Total Lost Days for the month in question, no time adjustments will be made.

If the net number of Actual Workdays Lost is more, then an excusable time extension may be granted. The Contractor must submit a Weather Time Impact Analysis supporting any alleged delays due to Unusually Severe Weather.

(e) Delays Due To Other Weather Conditions. Delays due to other unusually severe weather conditions (snow, extreme cold or heat, hurricanes, high winds, etc.) must be supported with a Weather Time Impact Analysis using historical weather data.

155.02. Delete the last paragraph and substitute the following:

The Construction Contract Time shown on the construction schedule for contract completion or for any interim completion dates shall be the calendar dates established in the contract.

155.04. Add the following to the first paragraph:

For a computer-generated CPM, use Primavera software or software that is file-compatible with Primavera.

Measure the smoothness/roughness of the final paved surface course after final rolling, within 14 days of completing roadway paving, before placing a surface treatment, and according to the designated type below. In addition, construct all pavement surfaces to meet the requirements of (c) below.

(a) Profile ride index (PRI). For type I or II pavement smoothness, furnish a California type profilograph and personnel to operate the profilograph. The CO will direct and observe its operation. Operate the profilograph in the “mode” such that the continuous plot produced can be reduced according to FLH T 504. Measure in the middle portion of each lane and exclude areas according to FLH T 504. Measure excluded areas according to (c) below.

Submit the trace to the CO.

A PRI will be calculated for each 0.1-mile lane of traveled way using a zero blanking-band.

The PRI will be determined according to FLH T 504. Bumps will be located using a 0.4-inch bump template.

(1) Type I pavement smoothness (PRI measurements for reconstructed and new roads). Measure the smoothness of the final paved surface course. The upper specification limit is 24 inches per mile for reconstructed and new roads. Defective areas are bumps in excess of 0.4 inches in 25 feet, 0.1-mile profile ride index greater than 28.5 inches per mile, or surfaces with a pay factor less than 0.75 as determined under Subsection 106.05.

(2) Type II pavement smoothness (PRI measurements for overlay, recycle with overlay, or milling with overlay projects). Before construction traffic, measure the smoothness of the existing surface. The existing surface is the original surface before overlaying, recycling, or milling. The existing profile ride index and standard deviation will be used to determine the upper specification limit.

For one-lift placement of the final surface:

USL1 = 0.71 * PRI0 + 0.39 * Sd0, but not less than 24 inches per mile

For two-lift placement of the final surface:

USL2 = 0.50 * PRI0 + 0.30 * Sd0, but not less than 24 inches per mile

Where:

USL1 = Upper specification limit for one lift rounded to the nearest whole number (inches per mile)

J-18

USL2 = Upper specification limit for two lifts rounded to the nearest whole number (inches per mile)

PRI0 = Existing surface profile ride index (inches per mile)

Sd0 = Existing surface profile standard deviation

Measure the smoothness of the final paved surface course. Defective areas are bumps in excess of 0.4 inches in 25 feet, 0.1-mile profile ride index greater than 1.5 times the calculated upper specification limit, or surfaces with a pay factor less than 0.75 as determined under Subsection 106.05.

(b) International Roughness Index (IRI). For type III, IV, V, or VI pavement roughness, furnish an inertial profiler conforming to AASHTO MP 11 and capable of meeting certification requirements of AASHTO PP 49. Provide a trained and qualified operator to operate the inertial profiler equipment. All equipment will be validated against a government profiler at the time of use. A cross correlation value will be determined for at least one random segment of at least 0.1-mile in length. Contractor and Government profilers will be cross correlated on the same day prior to the start of paving operations. Coordinate the profile verification date through the CO. At the preconstruction conference, provide the CO with a list of three or more possible dates in three or more different weeks that the profiler and operator will be available for cross correlation verification. The CO will determine the cross correlation segments. The minimum acceptable cross correlation value is 0.90.

Equipment failing to obtain a cross correlation value of at least 0.90 shall not be used.

Operate the inertial profiler in accordance with manufacturer’s recommendations and AASHTO PP 50. Provide a lead-in distance, after reaching the testing speed, of at least 150 feet. Furnish personnel to provide flagging operations as may be required.

For all pavement roughness types measure the pavement profile in both wheel paths and use an average IRI value. Immediately after obtaining the profile measurements provide the CO with an electronic file containing the profile data in an ERD format per AASHTO PP 50.

Analysis of the profile data will be made using the latest version of the Profile Viewer and Analysis (ProVAL) software. The most current version can be downloaded at http://www.roadprofile.com.

Areas of localized roughness will be identified using a report of continuous IRI with a base length of 25 feet. This will yield the IRI of every possible 25-foot segment. Any area for which the continuous report exceeds an IRI of 170 inches/mile will be considered a defective area requiring correction in accordance with Subsection 401.16(d).

A report of continuous IRI is defined as the roughness profile from “Profiles from Roughness”, TRR 1260, by M.W. Sayers. Its use for detection of localized roughness, as required here, is demonstrated in “Using a Ride Quality Index for Construction Smoothness Specifications”, TRR 1861, by M. Swan and S. Karamihas.

An IRI value will be determined for each 0.1- mile of traveled way. Cattle guards, bridges, driveways, parking areas, and turning or passing lanes, side roads and ramps less than 350 http://www.roadprofile.com/�

J-19 feet in length will be excluded from the calculation of IRI and determination of localized roughness. Straightedge excluded areas according to Subsection 401.16(c).

(1) Type III pavement roughness (IRI measurements for reconstructed and new roads). Measure the roughness of the final paved surface course. Defective areas are 0.1-mile segments with IRI values greater than 95 inches per mile or areas of localized roughness.

The pay adjustment factor for each 0.1-mile segment will be determined from Table 401- 3.

Table 401-3 Type III Pavement Roughness

Greater than 95.0 Defective Area

PFIRI = Pay factor for roughness. (Rounded to three decimal places)

IRI = International Roughness Index. (Rounded to one decimal place)

(2) Type IV, V, and VI pavement roughness (IRI measurements for overlay, recycle with overlay, or milling with overlay projects). Measure the roughness of the existing surface no more than 30-days prior to the start of construction. The existing surface is the original surface before overlaying, recycling, or milling. The existing IRI will be used to determine the percent improvement for each 0.1-lane mile segment. Measure the roughness of the final paved surface course. Defective areas are areas of localized roughness, 0.1-lane mile segments having IRI values greater than the defective limits in Table 401-4, and surfaces with a pay factor less than 0.750 as determined under Subsection 401.19.

The pay factor for roughness will be determined for each 0.1-mile segment length according to the following formula:

PFIRI = -0.00625(IRI) + (0.00625(USL) + 1.0) ≤ 1.050

PFIRI = Pay factor for roughness (rounded to three decimal places)

IRI = International Roughness Index (rounded to one decimal place)

USL = Upper Specification Limit

The maximum pay factor for roughness for any 0.1-lane mile segment will be 1.050. For overlay, recycle with overlay and milling with overlay projects determine the percent improvement. The percent improvement in IRI for each 0.1-lane mile segment length will be determined according to the following formula:

Percent Improvement = [(Original IRI – Final IRI) / Original IRI] x 100

Round percent improvement to one decimal place for each 0.1-lane mile segment. If the percent improvement for a 0.1-lane mile segment is less than zero then the maximum pay factor for roughness will be 1.000. When only one lift of asphalt concrete pavement is placed, if the percent improvement for a 0.1-lane mile segment is 25.0 percent or greater then the minimum pay factor for roughness for that segment will be 1.000. When multiple lifts of asphalt concrete pavement is placed, if the percent improvement for a 0.1-lane mile segment is 35.0 percent or greater then the minimum pay factor for roughness for that segment will be 1.000. Round Percent Improvement to one decimal place.

(c) Type VII pavement smoothness/roughness (straightedge measurement). Use a 10-foot metal straight edge to measure at right angles and parallel to the centerline. Defective areas are surface deviations in excess of 1/4 inch in 10 feet between any two contacts of the straightedge with the surface.

(d) Defective area correction. Correct defective areas from (a), (b), and (c) above. Obtain approval for the proposed method of correction. If no corrections are allowed, then bumps as defined by Subsection 401.16(a) and areas of localized roughness as defined by Subsection 401.16(b) will be assessed an additional deduction of $200 per incident. For areas of localized roughness and bumps within 25-feet of each other longitudinally and in the same lane, only one deduction of $200 will be assessed. If corrections of the defective areas defined in Subsection 401.16(b) are not allowed, then the pay factor will be 0.750. No other adjustments or deductions will be made if corrections are not allowed.

J-21

Re-measure corrected areas according to the specified type of pavement smoothness/roughness. The smoothness/roughness value obtained will replace the original value obtained will replace the original.

401.19. Delete the last paragraph and substitute the following:

When the bid schedule contains a pay item for Superpave hot asphalt concrete pavement type III, IV, V, or VI pavement roughness, a separate adjustment will be made for pavement roughness according to the following formula:

A2 = 40,000(PFAVE – 1.000)(L)

A2 = Adjustment to contract payment in dollars for pavement roughness.

L = Total project length in lane miles of traveled way minus excluded areas. Measure the project length to 3 decimal places.

PFAVE = Average Pay Factor for determined according to Subsection 401.16(b) after completion of corrective work. The formula for PFAVE is as follows:
