WSDOT Pay Item [CUG]
In bridge construction projects, a Pay Item refers to a defined unit of work for which the contractor is compensated under the terms of the construction contract. Each Pay Item is associated with a specific type of work, a measurement unit, and a unit price.
Each Pay Item corresponds to a clearly defined work activity (e.g., “Pile Foundation Installation,” “Concrete Slab Casting,” “Pre-stressed Girder Erection”).
The quantity is measured in units such as cubic feet (ft³), pounds (lb), feet (ft), square feet (ft²), or per item (each).
The contractor is compensated based on the agreed unit price, multiplied by the actual quantity of work performed.
Pay Items are used to calculate the contractor’s payment through interim and final progress payments (e.g., interim certificates or progress billings).
General
Description: The description provides an explanation of the Pay Item. When creating a pay item, its definition may be established either by specifying the input parameters or by selecting a pay item that has been defined in the database object.
Quantity Items: The measurable quantities associated with each Pay Item, indicating the amount of work to be completed or that has been completed.
3D Object: A digital three-dimensional representation of a physical component within the project, such as beams, columns, decks, and other bridge elements that have been modeled in 3D.
Item Quantity Parameter: ‘Item Quantity’ refers to the measured or calculated amount of work performed for a specific Pay Item in construction projects.
Unit Price: The price assigned per unit for each work item.
Total Quantity: It represents the entire amount of work or material required for a specific Pay Item in a project.
Unit of Measure [L.F./S.F./C.F./C.Y./LB./TON/EACH/L.S./HR/EST./CALC/S.Y./ACRE/MI./GAL./CM/DAY/MGAL/MBM/UNIT/HUND/CRHR/PLS]: "Unit of Measure" refers to the standard unit used to quantify a specific work item or material in construction and engineering projects. It defines how the quantity of work performed or material used is measured.
Common Units of Measure and Their Meanings
L.F.
Linear Foot — length measured in feet along a line
S.F.
Square Foot — area measured in square feet
C.F.
Cubic Foot — volume measured in cubic feet
C.Y.
Cubic Yard — volume measured in cubic yards
LB.
Pound — unit of weight
TON
Ton — typically a short ton
EACH
Each — unit count representing individual items
L.S.
Lump Sum — total price for a complete job or item
HR
Hour — unit of time measured in hours
EST.
Estimate — estimated quantity or cost
CALC
Calculated — calculated quantity or cost
S.Y.
Square Yard — area measured in square yards
ACRE
Acre — unit of area
MI.
Mile — unit of distance
GAL.
Gallon — unit of liquid volume
CM
Centimeter — unit of length
DAY
Day — unit of time
MGAL
Thousand Gallons — 1,000 gallons
MBM
Thousand Board Feet — unit for lumber volume (1,000 board feet)
UNIT
Unit — general unit of measure
HUND
Hundred — quantity of 100 units
CRHR
Crew Hour — work hours of a crew
PLS
Please Confirm / Plus — depending on context, usually means “please confirm” or “plus”
Total Cost: It represents the total sum of all expenses associated with a specific work item, material, or service. This amount is typically calculated as the product of the unit price and the quantity (i.e., unit price × quantity). For example, in the pay item “Concrete pouring,” the total cost is determined by multiplying the volume of concrete used by the unit price per cubic yard or cubic meter. This value reflects the overall monetary cost of the work performed, materials utilized, and services provided within a project. It is a critical figure for budgeting, bidding, cost control, and progress payment processes.
Category: The pay item category is determined based on this parameter.
WSDOT
A WSDOT pay item refers to a specific work or material component in a Washington State Department of Transportation project for which payment is made, with unit prices and quantities defined to determine contractor compensation.
When a WSDOT pay item is imported from the database, the parameters described below are automatically set.
Standard Item Number: In WSDOT projects, each work or material element is designated as a pay item. Each pay item is assigned a Standard Item Number by WSDOT, which standardizes the type and unit of the work. This ensures consistency across projects and facilitates payment and reporting processes. In summary, a pay item represents the work performed, while the Standard Item Number specifies its official WSDOT definition.
Estimate Sequence Number: An Estimate Sequence Number is a unique identifier assigned to each payment estimate submitted by the contractor for work performed. It indicates the payment estimate period to which the payment corresponds.
Standard Item Section: In WSDOT projects, work items are organized into Standard Item Sections to ensure consistency and facilitate effective management. Each section encompasses a specific type of work, such as earthwork, concrete operations, or pavement construction. This structure standardizes project references, technical specifications, and payment procedures.
In summary, a Standard Item Section represents a categorized grouping of work items within a project.
Prequal Code: In WSDOT projects, a Prequalification Code indicates that a contractor or supplier is qualified to perform a specific type of work. For each pay item, the corresponding Prequalification Code verifies that the contractor has been pre-approved based on technical capability, financial stability, and relevant experience. The code varies according to the type of work and determines the tasks a contractor is authorized to perform.
Prequalification Codes and Their Corresponding Work Types
The table below provides examples of common Prequalification Codes used in WSDOT projects, along with the types of work they authorize contractors to perform:
A01
General Construction
B02
Asphalt Paving
C03
Concrete Work
D04
Electrical Systems
E05
Bridge Construction
F06
Drainage & Utilities
G07
Landscaping / Erosion Control
H08
Traffic Signals / Signing
Note: This table provides examples of standard codes. Each project may have its own specific code assignments.
Item Use Notes: Explanatory notes or instructions specify how, when, and under what conditions a pay item should be used. In short, they serve as guidelines to ensure the correct application of the pay item.
