Section 1:
Issues Affecting Payments

Overview

Measure quantities in accordance with the contract as specified in Article 9.1, “Measurement of Quantities”
of the
Standard Specification
. Ensure that the Contractor completes work as provided in the contract and pay the Contractor according to the amount of work performed maintaining sufficient documentation to support all quantities paid.

Measurement of Quantities

Provide calculations for payments in the DWR remarks bubble. When measurements cannot be described as shown below, computer measurements or drawings for irregular areas will be acceptable as supporting documentation.
  • EXAMPLE:
    A section of riprap measures 100 FT by 3 FT and is 5 IN thick. Calculate the area and volume of the riprap.
    • Area = Length × Width = 100 FT × 3 FT = 300 SF
    • Area in SY = 300 SF ÷ 9 SF/SY = 33.33 SY
    • Depth = 5 IN x 1 FT/12 IN = 0.417 FT
    • Volume = Length × Width × Depth = 100 FT × 3 FT × 0.417 FT = 125 CF
    • Volume in CY = 125 CF ÷ 27 = 4.63 CY
  • EXAMPLE:
    A one-mile highway was striped with 4-in. white broken stripe. Calculate the quantity placed.
    • 1 MI = 5,280 FT
    • 1 broken stripe = 10 FT of stripe + 30 FT of spacing between stripes
    • 1 MI = 5,280 FT ÷ (10 FT + 30 FT) = 132 stripes per MI
    • 132 Stripes per MI x 10 FT of stripes = 1320 LF of stripes
Partial payments to an item of work can be made when agreed upon. Items such as embankment cannot truly be measured; therefore, payment can be made by percentage or by station range if earthwork tables are provided. Cast-in-place inlets are completed in multiple stages, so partial payments in the form of percentages can be made. Document reasons for partial payments in the payment portion of the DWR.

Plans Quantity Measurement

Measurement of actual quantities is not required if a pay item under “Measurement” states in part, “This is a plans quantity measurement Item.” The intent of plans quantity measurement items is to relieve Department personnel from performing quantity field measurements. Monthly estimates for plans quantity measurement items can be established by the quantities shown in the plans or with an established and agreed on payment formula such as a percentage of the total plan quantity installed.
Periodic field measurements and calculations can be performed to verify the required design plan dimensions but should not be used to establish quantities on plans quantity measurement items. Changes to plan quantity items is addressed in Article 9.2,
“Plans Quantity Measurement”,
 of the
Standard Specifications
.

Payments not to Exceed 10% of the Original Contract Amount

  • Item
     0100 Preparing Right of Way (ROW): total payment of this item will not exceed 10% of the original contact amount until Final Acceptance.
  • Item
     0502 Barricades, Signs, and Traffic Handling: total payment for this item will not exceed 10% of the total contract amount before Final Acceptance.

Payment of Items with Overweight Loads

Before paying for quantities over the legal weight limit, request copies of overweight permits from the Contractor. Overweight quantities may be paid if the permits are provided. Overweight quantities
cannot
 be paid if the load was transported on the designated Interstate system.

Quality Control (QC)/Quality Assurance (QA) Hot Mix Payments

Use the standard item and description codes to track the payment for QC/QA Hot Mix. Refer to the
SiteManager Contract Administration User Manual
for instructions
to add the standard item and description codes to the contract.

Road User Costs (RUC) Incentives and Disincentives

If not using the SiteManager milestone function, use the standard item and description codes to track the payment of incentives and disincentives on contracts with RUC. Refer to the
SiteManager Contract Administration User Manual
 for instructions to add these standard items to
the contract.

Force Account

Force account work is described under Chapter 7, Section 3, “Force Account and Interim Adjustments to the Contract”. Ensure
Form 316
, “Daily Report of Force Account Work”, is completed on a daily basis and signed by the Contractor. Collect the necessary documentation supporting the information on the form. Payment for force account work will be made on a created line item for that work.
