How to Read a Wage Determination: The BEST Guide for Prevailing Wage Projects

Understanding a Federal Wage Determination

Why reading a wage determination correctly affects construction payroll and compliance

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.

Navigating the SAM.gov Search System

When searching for determinations on SAM.gov, follow these steps:

Compare older and newer revisions to understand rate changes

1. 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

Step-by-step: How to Read a 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:

1. The construction type listed
2. The definition of that construction type

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

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
