The Contractor will be reimbursed for the direct cost billed by the Police Department with no additional payments for overhead or profit. The Contractor shall provide invoices from the Police Department to the RE for reimbursement. An estimated amount to cover these reimbursements has been included in the proposal. It is the intent of the project that any improvements that disturb pedestrian traffic areas will be reconstructed immediately upon disturbance/demolition to minimize any disturbance to pedestrian sidewalks, access and crosswalks. Should any prolonged disturbance or delays be encountered during construction the contractor shall install Temporary Sidewalk as required or as directed by the engineer in areas of high pedestrian traffic. No separate or individual payment shall be made for Temporary Sidewalk. SECTION 160 – PRICE ADJUSTMENTS THE ENTIRE SECTION 160 IS CHANGED TO: 160.01 DESCRIPTION This Section describes the requirements for price adjustments for fuel and asphalt usage. 160.02 MATERIALS (Intentionally Blank) 160.03 PROCEDURE 160.03.02 Asphalt Price Adjustment The Department will make price adjustments for asphalt binder usage. The Department will calculate asphalt price adjustments based on the quantities of Items containing asphalt binder constructed. Each month may be divided into two periods. Period one includes the first day of the month through the fourteenth day of the month. Period two includes the fifteenth day of the month through the last day of the month. Work starting on the fourteenth day of the month and continuing past midnight into the fifteenth day of the month will be included in period one for any price adjustments. Work continuing through midnight of the last day of the month into the first day of the next month will be included in period two. THE THIRD PARAGRAPH IS CHANGED TO: The price used for both the Basic and Monthly Price Indexes will be determined based on the performance grade of asphalt binder in the approved mix design for the asphalt mixture. Price adjustments may result in an increased payment to the Contractor for increases in the price index and may result in a reduction in payment for decreases in the price index. The Department will calculate the asphalt price adjustment by the following formula: A = (MA −

ction in payment for decreases in the price index. The Department will calculate the asphalt price adjustment by the following formula: A = (MA − BA)  T Where: A= Asphalt Price Adjustment MA = Asphalt Price Index for work performed in the time period immediately before the estimate cutoff date. BA = Basic Asphalt Price Index T= Tons of New Asphalt Binder1 1. The Department will determine the weight of asphalt binder for price adjustment by multiplying the percentage of new asphalt binder in the approved job mix formula by the weight of the item containing asphalt binder. If a Hot Mix Asphalt Item has a payment unit other than ton, the Department will apply an appropriate conversion factor to determine the number of tons of asphalt binder used. For Tack Coat, Prime Coat, MICRO SURFACING EMULSION, SLURRY SEAL EMULSION, and FOG SEAL SURFACE TREATMENT, the Department will calculate the weight of asphalt as follows: HELEN AVE., LAWRENCE AVE., FLORENCE PL., AND LOWELL AVE., IMPROVEMENTS PROJECT Page 30 of 76
