Center, 1-800-STAKE-IT, between the hours of 7:00 a.m. and 4:30 p.m., Monday through Friday, for information relative to the location of buried utilities.

It shall be the responsibility of the contractor to contact the utility companies in order for them to determine if there is a need to brace, shore, support and protect their facilities during the construction of the project.

Utility locations shown on the project plans are approximate, and all utilities are not necessarily

SP-18

shown. The possibility of conflicts with existing utilities exists. If conflicting utilities interfere with the contractor's normal progress towards completion of the project, the Pima County

Department of Transportation may, at its option, authorize the contractor to relocate said conflicting utilities by force account in accordance with the provisions of subsection 109-5.02 of the Standard Specifications and these Special Provisions.

(7) The monthly report shall include a detailed predecessor/successor analysis showing the predecessors, successors, logic ties, and constraints for each activity scheduled.

These activities shall be ordered by event number or activity number from least to greatest.

(8) All Extra Work shall be shown on an updated Schedule.

The automated system software shall be Primavera or approved equal.

No measurement or direct payment will be made for Contractor costs relating to preparation and

SP-21

submission of schedules and reports and revisions thereto, the cost being considered as included in the prices paid for contract items.

Float time is not for the exclusive use or benefit of either the Department or the Contractor.

Extension of time for performance may be granted to the extent that equitable time adjustment for the activity affected exceeds the total float or where otherwise justified, impact on the contract completion can be shown.

Concurrence of the Contractor's schedules by the Engineer is not to be construed as relieving the

Contractor of its obligation to complete the work within the contract time; or as granting, rejecting, or in any other way acting on the Contractor's requests for adjustments to the date for completing contract work, or claims for additional compensation. Such requests shall be processed in strict compliance with other relevant provisions of the contract.

The Contractor shall participate in a review and evaluation of the proposed Part I, Preliminary

Schedule, and Part II, Schedule, and monthly updated schedule by the Engineer. Any revisions necessary as a result of their review shall be submitted for concurrence to the Engineer within 10 calendar days after the review. The accepted Part II, Schedule, shall then be used by the

Contractor for planning, organizing, executing, and directing the work and for reporting progress of work accomplished. The Contractor shall furnish to the Engineer for project use a copy of the

Part II, Schedule, and a monthly updated schedule on a compatible computer disk of a size and configuration designated by the Engineer.

The Engineer shall complete review of Part I, Preliminary Schedule, and Part II, Schedule, within 15 calendar days of the receipt of each. No monthly progress payment will be made until Part I has been accepted. Within the next 60 calendar days after concurrence with Part I, Part II will be submitted and reviewed. If Part II has not been accepted within these 60 calendar days, progress payment will be withheld until Part II has been concurred with by the Engineer.

Failure of the Contractor to comply with the monthly updated Schedule requirements specified herein will be grounds for the Engineer to withhold an additional 10 percent of the monthly progress payments, in addition to the normal retention, until the Contractor is in compliance.

Additional money withheld will be paid upon compliance to the Contractor in the next scheduled monthly estimate. If the monthly updated schedule is not received by the 10th working day of each month, but received prior to the 25th of the month, five percent will be withheld until the following estimate.

SECTION 109 - MEASUREMENT AND PAYMENT

109-1 MEASUREMENT OF QUANTITIES of the Standard Specifications is modified to add:

The term “Dollar” or its abbreviation “USD” (US Dollar) when included in the bidding schedule

SP-22

as a unit of measurement, shall mean an allowance for the payment of the work in conformance with the provisions of Subsection 109-5.01.

(109FUEL_ADJUST, 7/08/22)

SECTION 109 - MEASUREMENT AND PAYMENT

109-13 COMPENSATION FOR FUEL ADJUSTMENT is hereby added to the Standard Specifications:

109-13.01 Fuel Cost Adjustment.

(A) General. The Agency will adjust monthly progress payments up or down as appropriate for cost fluctuations in diesel fuel as determined in accordance with these Special Provisions.

A fuel cost adjustment will be made when fluctuations in the price of diesel fuel, in excess of 15 percent, occur throughout this contract. The Agency will not provide such adjustments for fluctuations in the price of diesel fuel of 15 percent or less.

No adjustments will be made for fluctuations in the price of fuels other than diesel.

(B) Determination of Compensation. The base index price of fuel will be determined by the

Agency from the selling prices of diesel fuel published by OPIS (Oil Price Information Service).

The base index price to be used will be the price for Diesel fuel No. 2, Ultra Low Sulfur, PAD 5, City of Tucson. The reported average value for the Tucson area will be used.

The base index price for each month will be the arithmetic average of the selling price for diesel fuel, as specified above, shown in the last four reports received prior to the last Wednesday of the month.

This price will be effective as of the last Wednesday of each month, and will be posted on the

Arizona Department of Transportation (ADOT) website on or shortly after the last Wednesday of the month at: https://azdot.gov/business/contracts-and-specifications/bituminous-and-fuel-price-adjustment

This price may also be obtained from Contracts and Specifications Services at (602) 712 - 7221.

This price will be deemed the "initial cost" for diesel fuel on projects for which bids are opened during the following month.

The current index price for diesel fuel in subsequent months will be the base index price, determined as specified above, for the current month. The amount of adjustment per gallon will be the net difference between the "initial cost," adjusted by 15 percent, and the current index price. The monthly adjustment will be determined by the Engineer and included in the payment

SP-23

estimate as a fuel adjustment. For fluctuations in excess of 15 percent, fuel cost adjustments will only be made for current price index increases greater than 1.15 times the "initial cost" or for decreases less than 0.85 times the "initial cost." No calculation will be made for fluctuations in the current index price of 15 percent or less when compared to the "initial cost."

The number of gallons of diesel fuel used per month will be considered to equal 1.5 percent of the dollar amount of work reported by the contractor for each month. Such dollar amount will not include incentives earned by the contractor for pavement smoothness, thickness, or strength for Portland cement concrete pavements; for pavement smoothness or quality lots for asphaltic concrete pavements; for any other revenue derived from quality incentives; or for revenue accrued in the previous month for bituminous material cost fluctuations or diesel fuel price adjustments.

A monthly adjustment, if applicable, will be made on this quantity, as shown below:

AC)-(CPx

IC

0.015(Q) S =

Where: S = Monetary amount of the adjustment (plus or minus) in dollars CP = Current index price in dollars per gallon

IC = “Initial cost" as determined above, dollars per gallon

AC = Adjusted "initial cost" (1.15 or 0.85 times IC) in dollars per gallon Q = Dollar amount of work completed for the month

If adjustments are made in the contract quantities, the contractor shall accept any fuel adjustment as full compensation for increases or decreases in the price of fuel regardless of the amounts of overrun or underrun.

The value calculated above (plus or minus) will be adjusted to include sales tax and other taxes as applicable.

No additional compensation will be made for any additional charges, costs, expenses, etc.,…
