502.19 Basis of Payment The accepted work done under structur al concrete, of the
classes and for the types of w ork required, will be paid for at the Contract unit price per cubic yard, or at the Contract l ump sum price, for the respecti ve Contract items involved. Payment for both the unit price and the lump sum price items wi ll be full compensation for furnishing and installing bridge drains, pier nose armor, water stops, expansion joint filler, PVC or plastic tube drains, asphalt roll roofing (roofing felt) , asphalt for painting or covering various type of joints, all required sandblasting, hig h-pressure water cleaning, bonding, curing and joint sealing and all incidentals necessary to complete the work satisfactorily. No direct payment will be made for concrete ad mixtures. No price adjustments will be made to the lump sum bid for the respective items that are bid lump sum, except when quantity changes are directed by the Department. It will be the responsibility of the Contractor to verify the estimated qu antities prior to submitting bid documents. Transverse saw cut grooving of concrete wearing surfaces will be paid for at the Contract lump sum price, which shall be payment for furnishing all materials, labor and equipment, including depth gauges and all incidentals, to satis factorily complete the work. Payment for structural concrete culvert connection shall inclu de drilling and grouting the dowels into the existing headwall and excavation. Reinforc ing will be paid for under Pay Item 503.12, Reinforcing Steel, Fabricated and Delivered an d Pay Item 503.13, Reinforcing Steel, Placing. Reinforcing steel, railings, stone curbing and any material th at may be required for bridge lighting systems, will be measured and paid for separate ly as provided in the appropriate sections. Implementation of the QCP and costs associated with acceptance test sampling shall be incidental to related items. All costs associated with obtaining, testing and evaluating dr illed core specimens for dispute resolution will not be pa id for directly, but will be c onsidered incidental to related items. Pay adjustments will be made only for cast-in-place concrete. Pay adjustments shall be computed on the actual final quantity for unit price items. Pay adjustments shall be computed on the estimated quantity for lump sum items, except w hen precast deck panels are used, or when quantity changes are directed by the Departme nt. When precast deck panels are used, the precast deck panel quantity, as computed f rom the Working Drawings, shall be deducted from the estimated lump sum quantity to deter mine the new estimated quantity that will be used to compute pay adjustments. When De partment-directed quantity changes are made, this quantity shall be added to, or subtracte d from, the estimated lump sum quantity to determine the new estimated quantity that will be used to compute pay adjustments. When precast deck panels are used and Department- directed quantity changes 5-54 are made under the same lump sum item, the combined quantity ch ange shall be added to, or subtracted from, the estimated lump sum quantity to determine t he new estimated lump sum quantity that will be used to compute pay adjustments. Pay adj ustments will be made according to the formula in Section 502.194. P, the unit value for pay adjustment purposes, is specified in Special Provision Section 502, Structural Concr ete (QC/QA Acceptance Methods). P values, as specifie d in Special Provision Section 502, reflect the price per cubic yard for all pay adjustment purposes. 502.191 Pay Adjustment for Compressive Strength, Methods A and B Pay factors (PF) for pay adjustments for compressive strength will be deter mined using the Quality Level Analysis as specified in Section 106. 502.192 Pay Adjustment for Permeability, Methods A and B Pay factors (PF) for pay adjustments for Permeability will be determined using the Q uality Level Analysis as specified in Section 106. Values less than 10 KOhm-cms for Class A concrete or 11 KOhm-c ms for Class LP concrete shall be subject to rejection and replacement, at no a dditional cost to the Department. 502.193 Pay Adjustment for Air Content, Methods A and B Pay f actors (PF) for pay adjustments for air content will be determined using the Qualit y Level Analysis as specified in Section 106. 502.194 Pay Adjustments for Compressive Strength, Permeability and Air Content, Methods A and B The Composite Pa y Factor (CPF) for each lot of concrete shall be computed as follows: CPF = [(Compressive Strength PF-1)(0.20)] + [(Air Content PF- 1)(0.40)] + [(Permeability PF-1)(0.40)] The pay adjustment for each lot of concrete shall be compute d as follows: Lot Pay Adjustment = P x CPF x Lot Size There will be no positive pay adjustments for Method B Concret e. 502.195 Pay Adjustment Method C When the Department determine s that Method C concrete which does not meet the specified limits may remain in place, payment will be reduced in accordance with Table 6. The quantity to which the pay reduction shall apply will be determined by the Resident.
