Site work and paving for a playground / park / athletic field in Columbia, Tennessee. Completed plans call for site work for a playground / park / athletic field; and for paving for a playground / park / athletic field.

Achieve Substantial Completion of the Work on August 2, 2024. A Payment, Performance, Labor and Materials (PPLM) Bond in the amount of 100% of the contract sum, issued by a bonding company licensed to do business in the state of Tennessee and acceptable to the Owner. Bond is required of the successful bidder to guarantee faithful performance of work under the contract. In the event the successful Bidder to whom the contract is awarded fails to execute a satisfactory contract and PPLM bond and proof of insurance - then said bidder shall be eliminated and shall forfeit his 5% bid bond and be liable for any loss occasioned to the Owner because of such failure. Maury County reserves the right to accept or reject any and all bids to negotiate both prices and specifications. No bids shall be withdrawn for a period of 60 days subsequent to the opening of bids without the consent of Maury County. Document note: Bid documents shall be obtained electronically or in hard copy by Prime Bidders only (a prime bidder is a General Contractor who intends to bid on the entire site package and who purchases plans) via the Designer, in accordance with the Instructions to Bidders. Checks will be refunded in full to any and all Prime Bidders who return Contract Documents to Kline Swinney Associates in good condition within ten (10) days after the bid opening day. A. This Special Provision covers the method of price adjustment for bituminous materials. B. The normal bid items in the contract covering the bituminous material shall remain the same, but the contract unit bid prices for these items will be adjusted to compensate for increases and decreases in the Contractor's bituminous material cost in the following manner: 1. A, “Basic Bituminous Material Index” will be established by the Tennessee Department of Transportation prior to the time the bids are opened. This “Basic Bituminous Material Index" is the average of the current quotations on P.G. 64-22 from suppliers furnishing asphalt cement to Contractors in the State of Tennessee. These quotations are the cost per ton f. o. b supplier’s terminal. 2. The, “Basic Bituminous Material Index" for this project is the February 2023 Index. 3. The, “Monthly Bituminous Material Index" is also established on the first day of each month by the same method. The “Monthly Bituminous Adjustment Factor" is the difference (+/-) between the, “Basic Bituminous Material Index" and the, “Monthly Bituminous Material Index.” 4. The, “Monthly Bituminous Adjustment Factor" shall be applied to the contract unit price bid provided the increase of decrease differs 5% of more from the, “Basic Bituminous Material Index". The Engineer reserves the right to alter the quantities of material or modify the design if the change in prices warrants material or design substitution. If adjustments are made in quantities or design, the Contractor shall accept the unit price bid or the applicable monthly adjusted unit prices as full compensation for all work performed according to the provisions of Subsection 104.02 of the Standard Specifications. 5. The adjustment will be calculated in accordance with the following formula only when the percent change of price indexes is five or greater: PA = [lc - lb] x T Where: PA = Price Adjustment for Adjustment Month lb = Basic Bituminous Material Index Ic = Monthly Bituminous Material Index T = Tons bituminous material for Adjustment Month 6. Price adjustment will be applied to all asphalt cement, asphalt emulsion, or bituminous material used for paving on this project. 7. The quantity of virgin asphalt cement in tons subject to price adjustment in recycled mixes shall be the product of the total tons of each mix multiplied by the difference between: (1) the percent of asphalt cement specified for bidding purposes; and (2) the percent of asphalt cement obtained from the recycled asphaltic material used in each mix. No price adjustment under this special provision for increases and decreases in the Contractors cost for virgin asphalt cement in recycled mixes will be allowed for asphalt cement content in excess of the percent specified for bidding purposes, as all payment adjustments for asphalt cement in the mix design of recycled mixes in excess of the percent of asphalt cement specified for bidding purposes will be made in accordance with the Standard Specifications. 8. The price adjustment for increases and decreases in the Contractor's cost for virgin asphalt cement in recycled mixes will be calculated as follows when the percent change in price indexes is five or greater: PA = [lc - Ib] x [BA - RA] x Tm 100 Where: PA = Price Adjustment for Adjustment Month Ib = Basic Bituminous Material Index Ic = Monthly Bituminous Material Index BA = Percent asphalt specified for bidding purposes RA = Percent asphalt obtained from recycled asphaltic material used in each mix Tm = Tons asphalt mix for adjustment month 9. The above procedure for calculating price adjustments for recycled mixes is also applicable to mixes consisting of one hundred percent virgin material when the asphalt cement is not a separate bid item and the asphalt cement in each mix is established for bidding purposes. A totally virgin mix is a special case in which the percentage of asphalt obtained from recycled asphaltic material is zero (i.e., RA = 0). Removal and disposal of designated foundations, pavements, concrete, curbs, culverts, utilities and other structures. A. Preparing subgrade to receive a base or pavement. B. Placing and compacting base material.
