How to Calculate Overtime Pay for Construction Workers

TL;DR:

Under federal law, overtime kicks in after 40 hours in a workweek at 1.5x the regular rate. But in construction, it’s rarely that simple. If a crew member worked two different jobs at different rates, you need a weighted average calculation. 

Several states, including California and Colorado, add daily overtime thresholds on top of the federal rule. And if you skip it, the DOL can pull back wages up to three years.

Overtime is one of those payroll line items that looks simple until you’re staring at a week where one guy worked 26 hours as a laborer and 22 as an operator, or a California crew hit 9 hours on a Tuesday. At that point, time and a half after 40 stops covering it.

This guide covers how to calculate overtime pay in every construction scenario you’re likely to hit: federal rules, state rules, multi-rate crews, salaried crew members, and what it costs you if you get it wrong. Good job management starts with knowing where the exposure is.

What is overtime pay, and which construction workers are entitled to it?

Overtime pay is the premium an employer owes a non-exempt employee for every hour worked beyond 40 in a single workweek. Under the Fair Labor Standards Act (FLSA), that premium is at least 1.5x the employee’s regular rate of pay. [DOL Fact Sheet #23, 2019]

Almost every construction trades worker (laborer, carpenter, electrician, plumber, ironworker, equipment operator) is non-exempt and entitled to overtime. Non-exempt means the FLSA applies to that worker, so overtime is mandatory, not optional.

Exempt vs. non-exempt in plain language

Exempt employees aren’t entitled to overtime. They typically earn a weekly salary above $684 and hold executive, administrative, professional, outside sales, or IT roles. Non-exempt employees must receive overtime for hours beyond 40. If a crew member earns less than $684 per week on a salary basis, or is paid hourly at any rate, they are non-exempt and overtime applies.

Misclassification is the single most common reason construction employers face DOL investigations. Getting this wrong exposes back wages going back two to three years, depending on whether the violation is deemed willful. A field supervisor earning $650 per week who has been paid a straight salary with no overtime is a live liability right now.

The FLSA’s overtime requirement can’t be waived by agreement between employer and employee — not even in writing. [DOL Fact Sheet #23, 2019] An announcement that overtime must be pre-authorized doesn’t eliminate the obligation to pay it for hours actually worked. If the work happened, the overtime is owed.

That obligation lands on whoever is running payroll. For many construction companies, that means one person manually checking hours every day, job by job, to catch overages before they compound.

I wanna emphasize this is done visually and by checking numbers. So here on Friday, he’s 12 hours overtime. Saturday, 12 hours overtime. So whoever’s doing this is looking at it every day, can’t afford to take a day off because they lose where they’re at.

How to calculate overtime pay: step-by-step with construction examples

Here’s how to calculate overtime pay in the three scenarios every construction payroll admin runs into. Each one comes from two sources of complexity: crew members who split a week across multiple pay rates, and state rules that add daily thresholds on top of the federal weekly one. The weighted overtime calculation is Scenario 3. Most payroll guides skip it entirely.

Scenario 1: Standard hourly worker

Step 1: Overtime rate = Hourly wage x 1.5

Example: $28/hr x 1.5 = $42.00 overtime rate

Step 2: Overtime hours = Total hours worked minus 40

Example: 47 hours worked minus 40 = 7 overtime hours

Step 3: Overtime pay = Overtime rate x Overtime hours

Example: $42.00 x 7 = $294.00

Step 4: Gross pay = (Regular rate x 40) + Overtime pay

Example: ($28 x 40) + $294 = $1,120 + $294 = $1,414.00 gross pay with overtime

Scenario 2: Salaried non-exempt worker

Salaried employee overtime works like hourly overtime, with one extra step. A salaried construction worker is non-exempt if their weekly salary is under $684, or if their primary duties are manual and physical rather than managerial. To calculate overtime pay, first establish the hourly equivalent.

Hourly rate = Weekly salary / Standard workweek hours

Example: $900/week / 40 hours = $22.50/hr

Overtime rate: $22.50 x 1.5 = $33.75/hr

For 46 hours worked: ($22.50 x 40) + ($33.75 x 6) = $900 + $202.50 = $1,102.50 total

Scenario 3: Multi-rate week (weighted average overtime)

This is the scenario most generic overtime calculators miss entirely. When a crew member works at two different rates in the same week, the regular rate for overtime purposes is the weighted average of those rates. [DOL Fact Sheet #23, 2019]

For payroll admins at companies with crews moving between jobs mid-week, this is a Friday afternoon problem every single week.

He’s on 3 different jobs. After 40 hours, I have to put the hours of overtime in the overtime column because we’re billing off this spreadsheet, and we’re billing it overtime. So I have to be looking and go, oh, shoot. He’s at 40. Okay. At this time, let me see. So I’m gonna put 3 and a half hours on this day in overtime now for this phase code.

Weighted average overtime: worked example

Worker clocks 20 hours as a laborer at $26/hr and 28 hours as an equipment operator at $34/hr. Total: 48 hours, 8 overtime hours.

Step 1: Total straight-time earnings

(20 hrs x $26) + (28 hrs x $34) = $520 + $952 = $1,472

Step 2: Weighted average regular rate

$1,472 / 48 hrs = $30.67/hr

Step 3: Overtime premium (the additional 0.5x, since straight time is already paid for all 48 hours)

$30.67 x 0.5 = $15.34 overtime premium pay rate

Step 4: Total overtime premium

$15.34 x 8 OT hours = $122.72

Step 5: Gross pay for the week

$1,472 + $122.72 = $1,594.72

The regular rate of pay cannot be lower than the applicable minimum wage. [DOL Fact Sheet #56A, December 2019] Non-discretionary bonuses, such as production bonuses, safety bonuses, and attendance bonuses, must be included in the regular rate before calculating overtime. Discretionary bonuses are excluded.

AV Decking: $150,000+ recovered in six weeks

AV Decking ran payroll on project manager estimates that defaulted to 10 hours per day, regardless of actual hours worked, across 65 to 120 field employees on 25 to 40 active jobsites. Supervisors were guessing. The timesheet data feeding into overtime calculations was wrong before it ever reached payroll. 

After switching to Workyard GPS time tracking, every clock-in was verified at the jobsite. Within six weeks, AV Decking had recovered more than their full projected annual savings.

We’ve had at least a solid six weeks now with all of our guys fully on the app, and in six weeks, we actually over exceeded that $150,000 that we had originally estimated for an entire year.

Overtime pay quick-reference: common construction wages

BLS data from July 2024 shows average hourly earnings for construction production workers at $35.80. [Home Builders Institute, Fall 2024 Construction Labor Market Report, citing BLS CES data] The table below covers the $18 to $35 range, representing the majority of non-supervisory construction trades.

Hourly Rate	Regular Rate	1.5x Overtime Rate	2x Double Time
$18.00	$18.00	$27.00	$36.00
$20.00	$20.00	$30.00	$40.00
$21.00	$21.00	$31.50	$42.00
$22.00	$22.00	$33.00	$44.00
$22.50	$22.50	$33.75	$45.00
$23.50	$23.50	$35.25	$47.00
$24.00	$24.00	$36.00	$48.00
$25.00	$25.00	$37.50	$50.00
$27.00	$27.00	$40.50	$54.00
$28.00	$28.00	$42.00	$56.00
$30.00	$30.00	$45.00	$60.00
$32.00	$32.00	$48.00	$64.00
$35.00	$35.00	$52.50	$70.00

Note: Double time applies in California for hours over 12 in a day or hours worked on the 7th consecutive day of a workweek.

State overtime rules that matter for construction contractors

State overtime laws must be checked alongside federal law. Federal law sets the floor: overtime after 40 hours per workweek at 1.5x. Where state law is more protective than federal law, the state standard applies. Employers cannot choose the lesser requirement. [DOL Handy Reference Guide to the FLSA, current] 

For multi-state contractors, this means applying each state’s rules to the hours worked in that state. How to calculate overtime pay in California is a separate question from any other state, because California stacks three thresholds on top of the federal rule.

State	When Overtime Applies	Note for Construction
Federal (FLSA)	Over 40 hrs/week	Baseline for all states
California	Over 8 hrs/day; over 40 hrs/week; 7th consecutive day (2x after 12 hrs in a day)	Highest compliance risk for construction crews
Alaska	Over 8 hrs/day or over 40 hrs/week	Daily threshold, no double-time rule
Colorado	Over 40 hrs/week, 12 hrs/day, or 12 consecutive hrs	Long-shift rule catches extended construction days
Nevada	Over 40 hrs/week; over 8 hrs/day if worker earns below 1.5x state minimum wage	Wage threshold determines which rule applies
Minnesota	Over 48 hrs/week (unless FLSA applies)	FLSA supersedes for most construction employers
Kansas	Over 46 hrs/week (unless FLSA applies)	Same FLSA caveat
Washington	Double time possible on public works projects	Check prevailing wage requirements

California: highest-risk state for construction overtime compliance

California adds three overtime layers on top of the federal weekly threshold:

• 1.5x after 8 hours in a single day
• 1.5x for the first 8 hours on the 7th consecutive day of a workweek
• 2x for any hours over 12 in a single day, or any hours after 8 on the 7th consecutive day

A crew member who clocks a 13-hour day in California has triggered three different pay rates in one shift: straight time for hours 1 through 8, 1.5x for hours 9 through 12, and 2x for hour 13. A payroll admin running this manually has to catch all three every time.

Green Wall Tech: California compliance without the admin burden

Green Wall Tech needed a time tracking system that could satisfy California’s minute-by-minute compliance requirements without adding administrative burden on field crew. California law requires exact clock-in and clock-out times, job code attribution, and signed daily attestations. 

Doing that manually meant a payroll admin chasing corrections every week. Workyard’s GPS time clock let crew members clock in, select their job and cost code, and get to work in under 10 seconds, with every punch GPS-verified and timestamped.

California wants it down to the minute, right? It wants an exact clock in; it wants an exact clock out. So we needed a solution that would be easy enough for guys that want almost zero administrative responsibility whatsoever for them to be able to work to meet those kinds of standards. And Workyard was that kind of solution.

When a crew works across state lines in the same week

When a worker clocks hours in two different states during the same workweek, the employer must apply each state’s overtime rules to the hours worked in that state. You cannot average the rules across the week or apply the home-state rule to all hours.

For contractors whose crews regularly cross state lines, this isn’t an edge case. It’s a weekly payroll decision, and getting it wrong by defaulting to the home-state rule is the kind of mistake that shows up in a DOL audit years later.

In North Dakota, it’s 40 hours in a work week. We are right down the border, go across the river, and now we’re in Minnesota. Minnesota is 8 hours a day. So that’s the tricky part because when you cross over, you got that issue where you have to track a little differently.

Real-world example: a crew member clocks 4 days in Nevada and 2 days in California in the same week.

• Nevada days: no daily overtime threshold for workers earning above the state minimum wage trigger. Weekly overtime applies after 40 hours.
• California days: daily overtime applies regardless of total weekly hours. If the crew member clocked 10 hours on either California day, 2 of those hours are at 1.5x.
• You cannot apply Nevada’s rule to the California days.

Border-state pairs where this comes up regularly in construction: Nevada/California, Oregon/Washington, North Dakota/Minnesota, and Idaho/Oregon. If your crews cross these lines, your payroll process needs to track where hours were earned, not just total hours accumulated.

What happens if you don’t pay overtime: the real penalties

The DOL Wage and Hour Division recovered $259 million in back wages for nearly 177,000 workers in fiscal year 2025, an average of $1,465 per worker. [DOL WHD FY2025 Enforcement Data] 

Construction is consistently among the highest-violation industries targeted by WHD investigations. Knowing how to calculate overtime pay correctly is the first line of defense. The employer penalty for not paying overtime goes beyond back wages.

How DOL investigations start

A DOL Wage and Hour investigation most often begins with a current or former employee complaint. The WHD can examine all employment records going back up to two years for non-willful violations, or three years if the violation is deemed willful.

What you owe if found in violation

• Back wages: every unpaid overtime dollar for every affected worker during the lookback period.
• Liquidated damages: an equal amount on top of back wages, effectively doubling the total owed. Employers can avoid liquidated damages only by demonstrating good faith and reasonable grounds to believe they were in compliance.
• Civil money penalties: up to $1,000 per willful or repeat violation. [DOL Employment Law Guide: Minimum Wage and Overtime Pay, current]
• Criminal prosecution: willful violations can result in criminal charges, fines, and imprisonment.

A Guam construction company faced this directly: the DOL required the company to pay $86,000 in back wages to 75 workers for paying overtime at straight-time rates, plus an additional $23,000 in civil penalties for willful violations. The company also failed to maintain accurate records of hours worked — a separate FLSA violation on top of the wage penalties. [DOL WHD Enforcement News Release, 2020]

A common mistake that triggers willful-violation classification

Announcing that overtime requires pre-authorization doesn’t eliminate the obligation to pay it. If a crew member exceeds 40 hours without prior approval, the overtime is still owed. Employers who take the position that unauthorized overtime doesn’t need to be paid are converting a wage violation into a willful violation, which extends the lookback period from 2 years to 3 years and triggers higher penalties.

Records are as important as payments

The FLSA requires employers to keep accurate records of hours worked for all non-exempt employees. Contractors on public works projects face additional certified payroll requirements on top of the standard FLSA recordkeeping rules. 

A contractor with no reliable records can’t prove what was paid or when. In any dispute, the absence of records typically resolves in the crew member’s favor. The recordkeeping obligation is separate from the payment obligation.

What a defensible audit trail looks like in practice

A large interior finishing contractor with 50+ employees needed more than accurate payroll processing. They needed time records that could hold up in a DOL investigation: documentation of every hour worked, every change made to a time entry, and a clear chain of custody for every pay period. 

Manual timesheets couldn’t provide that. Workyard logs every punch, every edit, and every approval, with timestamps and user attribution on each change. That’s a defensible record for every employee, every week.

Workyard is one of the few [tools] that does everything that we would need it to do to be able to record time, view the changes to time, track the changes to time… Workyard already has the audit trail of all the changes.

How construction companies track overtime without doing it by hand

Getting accurate inputs is the hard part, not the math. Most payroll admins catching overtime errors after the fact aren’t working from the wrong formula — they’re working from wrong inputs: a project manager who submitted estimated hours, a crew member who forgot to clock out, a week where someone split time across three jobs and nobody set up the multi-rate split.

Workyard’s analysis of 280 contractor discovery calls found that nearly 1 in 3 construction businesses identify labor compliance, including overtime rules, union pay codes, and state wage laws, as a primary operational risk. Workyard is workforce management software especially built for construction businesses.

Get the inputs wrong and everything downstream is wrong: real-time labor costs are wrong, and the margin calculation at job closeout is wrong. 

Most off-the-shelf payroll tools require manual configuration to handle weighted average overtime or California daily OT rules — a setup most contractors never complete.

GPS-verified clock-ins fix the input problem

Workyard GPS time tracking requires crew members to clock in when they arrive at the jobsite and clock out when they leave. Workyard verifies each clock-in against the jobsite’s geofence. If a crew member is not on site, it flags the punch for supervisor review. The hours that feed into the overtime calculation are hours actually worked at the job location, not estimates, not defaults.

Automated overtime rules replace the manual calculation

Overtime rules are automatically applied to accumulated hours. For California contractors, daily overtime is calculated at the 8-hour threshold, double time at the 12-hour threshold, and the 7th-day rule without a payroll admin manually checking each day’s hours. 

For multi-state crews, state-specific rules are applied to hours by location. For multi-rate weeks, Workyard runs the weighted average calculation. The output that reaches payroll is already correct.

Payroll integration cuts the re-entry step

Workyard integrates directly with QuickBooks, ADP, Gusto, and other payroll platforms. Approved timesheet data exports to payroll without manual re-entry. The hours Workyard GPS-verified in the field are the hours that reach the paycheck, with no spreadsheet step in between where a figure can be transposed.

Allied Restoration: three months of clean payroll after switching

Workyard gave me a boost in confidence that I could identify issues and come up with a solution. I can now say that we haven’t had a payroll issue in 3 months.

Allied Restoration was adding headcount faster than their payroll process could keep up. Time tracking errors compounded each week: wrong clock-outs, missing job codes, hours landing on the wrong cost center. Every Friday meant a payroll admin chasing corrections instead of closing the books. 

After implementing Workyard, the errors stopped. Three months of clean payroll runs, saving $1,000 per month in admin overhead.
