What is a Wage Determination?
A wage determination is a document issued by the U.S. Department of Labor that sets required wage rates and fringe benefits for specific job classifications on prevailing wage projects. Understanding how to read it correctly ensures workers are paid properly and helps contractors avoid compliance risks.
How to read a wage determination correctly is one of the most important steps in Davis-Bacon compliance. It is one of the most misunderstood and most critical skills in prevailing wage compliance. Wage determinations control worker pay, fringe benefits, classifications, geographic coverage, and audit outcomes. For payroll teams, misreading even one section can result in underpayments, restitution, or withheld contract funds.
A wage determination must be read in full. Rates alone are not enough. Classifications, definitions, geography, modifiers, and footnotes all matter.
This quick guide walks through how to read a wage determination correctly, using the same technical details auditors and regulators rely on.
Key definitions you should know
Wage Determination – A document issued by the U.S. Department of Labor that sets minimum wage and fringe benefit requirements for laborers and mechanics on Davis-Bacon covered projects.
Classification – The type of work an employee performs on a project. Classifications are duty-based, not job-title-based.
Fringe Benefits – Hourly benefit amounts that must be paid in addition to base wages, either as bona fide benefits or cash.
Navigate the SAM.gov Search System
When searching for determinations on SAM.gov, follow these steps:
Compare older and newer revisions to understand rate changes
- Choose Your Search Type:
- DBA/I do not know the number – For construction-related work
- SCA/I do not know the number – For service contracts
- I do know the number – If you have the exact determination number
- I do not know the number – For general research
2. Filter Your Search:
- Enter the state, county, and work type
- For pre-2019 determinations, uncheck "Active Only" and enter the year in keywords
3. Review Revision History:
- Always check the "History" button first
- Match the revision date to your project's award date
How Do You Find the Correct Wage Determination?
1. Understand the wage determination number
Each wage determination includes an identifier with three components:
- State code
Two-character abbreviation such as GA for Georgia - Year
The year the determination was issued or revised - Four-digit identifier
A unique number for that determination, sometimes shortened
These components help confirm you are using the correct determination for the contract and award date.
2. Identify the construction type and definition
Davis-Bacon wage determinations fall into four construction categories:
- Building
Commercial buildings, schools, hospitals - Highway
Roads, streets, highways, runways - Heavy
Dams, water lines, sewer projects, dredging - Residential
Single-family homes, townhouses, apartments
Always read both:
- The construction type listed
- The definition of that construction type
east or west of the train station in Little Falls.
Some determinations list multiple construction types or restrict scope to specific work, such as dam construction only. Never assume coverage based on the category name alone.
3. Consider Service Contract Act differences
Unlike Davis-Bacon determinations, Service Contract Act determinations do not use construction categories. They list classifications by region only, and those classifications can be vague.
Definitions may be modified within the determination. Read carefully to confirm the work performed falls within scope.
4. Review geographic coverage and exclusions
Geographic scope is not always straightforward.
Key considerations:
- Some determinations apply statewide
- Others apply only to specific counties or cities
- Some classifications apply only to parts of a county
- Exclusions may apply to tribal lands or special zones
A county listed at the top does not guarantee all classifications apply countywide.
Example:
In Herkimer County, New York, classifications may differ east or west of the Little Falls railroad station. Mapping tools like Google Maps are often required to confirm coverage.
5. Interpret rate identifiers correctly
Each classification group begins with a rate identifier, such as:
- UAVG
Based on union averages where no single majority rate exists - SU
Based on a weighted survey average - No prefix
Based directly on a local union agreement
Rate identifiers explain how the rate was derived. They do not change how classifications are applied.
6. Account for area modifiers and specificity
Rates may vary based on:
- Geographic sub-areas
- Equipment size or capacity
- Distance or zone pay
- Specific work conditions
Power equipment operators are commonly grouped by numbered categories, each listing qualifying equipment. Accurate time tracking by equipment type is essential.
7. Find the correct classification
To identify the correct classification:
- Match classifications to actual work performed
- Start with the most specific classification
- Move to broader classifications only if no exact match exists
- Remember that some work, such as welding, inherits the classification of the primary task
Never assume classifications are consistent across different determinations, even within the same state.
8. Understand wage and fringe requirements
Each classification includes:
- A base hourly wage
- A fringe benefit amount
Fringes:
- Must be paid in addition to base wages
- May be benefits or cash
- May be expressed as fixed amounts or percentages
- Must be annualized, not limited to government work
Some classifications include additional fringe modifiers such as:
- Vacation accruals
- Holiday pay
- Tenure-based benefits
9. Review zone pay and holiday rules
Zone pay may apply for remote or difficult locations and is often based on distance measurements.
Holiday requirements may:
- Be explicitly listed in the determination
- Differ from federal holiday definitions
- Include state-specific holidays
Always check both the determination and applicable state law.
10. Wage Determination Classification Groups and Work Types
Many determinations use numbered groups instead of descriptive classifications:
- Accurate time tracking by specific equipment type is essential for compliance
- Power equipment operators are commonly organized by groups
- Each group contains detailed lists of qualifying equipment or tasks
What Are Common Wage Determination Mistakes?
Common mistakes when reading wage determinations include:
- Using the wrong determination for the project location
- Misclassifying workers based on job title instead of duties
- Ignoring fringe benefit requirements
- Skipping footnotes or special conditions
- Using outdated revisions
These errors can lead to underpayment, compliance violations, and costly back wages.
Practical tips for construction payroll teams
- Read the entire determination, including footnotes
- Never rely on rate tables alone
- Document duty-based classification decisions
- Track time by task and equipment
- Re-evaluate classifications when work changes
Final takeaways
- Wage determinations are technical documents, not summaries
- Classification accuracy is the foundation of compliance
- Geography, modifiers, and footnotes matter
- Each determination must be evaluated independently

Basic Wage Determination Q&A —
What is a Wage Determination?
A wage determination is a formal decision or ruling by a government authority that establishes the minimum wage rates and fringe benefits for various construction job classifications within a specific geographic area. These determinations are often applied to government-funded construction projects and are designed to ensure that workers receive fair compensation. The wage determination outlines the prevailing wage rates that contractors must pay to employees working on the project, taking into account the different job classifications and types of work involved. It serves as a guide for contractors to adhere to specific labor standards and helps prevent the exploitation of workers by setting minimum wage standards for the relevant industry and region.
What is a Wage Determination Number?
A wage determination number is a unique identifier assigned to a specific wage determination issued by a government agency. This number is used to differentiate and reference individual determinations, making it easier for contractors, employers, and other stakeholders to identify and apply the correct prevailing wage rates for a particular project.
The wage determination number typically includes information such as:
- State Code: A two-character code representing the state for which the determination is applicable (e.g., GA for Georgia).
- Year: The year in which the determination was revised or issued.
- Internal Identifier: A numerical or alphanumeric code used internally by the issuing agency for tracking and organizational purposes.
Contractors and employers refer to the wage determination number when determining the appropriate prevailing wage rates and classifications for specific job roles within a given project, ensuring compliance with prevailing wage laws and regulations.
