# Pay Item \[STG] ## Pay Item 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. ![image-20251020-121248.png](https://openbrim.atlassian.net/wiki/download/attachments/3141664855/image-20251020-121248.png?api=v2) **Quantity Items:** The measurable quantities associated with each Pay Item, indicating the amount of work to be completed or that has been completed. ![image-20251020-121836.png](https://openbrim.atlassian.net/wiki/download/attachments/3141664855/image-20251020-121836.png?api=v2) * **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.![image-20251020-122300.png](https://openbrim.atlassian.net/wiki/download/attachments/3141664855/image-20251020-122300.png?api=v2) * **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.![image-20251020-122409.png](https://openbrim.atlassian.net/wiki/download/attachments/3141664855/image-20251020-122409.png?api=v2) **Total Quantity:** It represents the **entire amount** of work or material required for a specific **Pay Item** in a project. ![image-20251020-122619.png](https://openbrim.atlassian.net/wiki/download/attachments/3141664855/image-20251020-122619.png?api=v2) **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. ![image-20251020-123123.png](https://openbrim.atlassian.net/wiki/download/attachments/3141664855/image-20251020-123123.png?api=v2) #### Common Units of Measure and Their Meanings | Abbreviation | Meaning | | ------------ | -------------------------------------------------------------------------------------- | | 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” | ![image-20251020-123303.png](https://openbrim.atlassian.net/wiki/download/attachments/3141664855/image-20251020-123303.png?api=v2) **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. ![image-20251020-123408.png](https://openbrim.atlassian.net/wiki/download/attachments/3141664855/image-20251020-123408.png?api=v2) **Category:** The pay item category is determined based on this parameter. ![image-20251020-123549.png](https://openbrim.atlassian.net/wiki/download/attachments/3141664855/image-20251020-123549.png?api=v2)
