Construction Time Theft Costs and How to Prevent It

A few unrecorded minutes per worker each day can add up to tens of thousands of dollars across a crew and a year. Time theft in construction means paying for time nobody worked, through buddy punching, padded hours, or breaks that run long without a clock-out. It’s a separate problem from stolen tools and materials, which usually get more attention.

This guide covers what time theft costs, how it shows up on jobsites, and why older tracking methods miss it. It also explains how GPS-verified clock-ins help, how to work out ROI, and how to roll them out. GPS clock-ins reduce the chances for time theft, but they aren’t a cure-all.

How Much Does Time Theft Cost Construction Companies?

Time theft is sometimes estimated at 1.5% to 5% of gross payroll. Treat this as a general planning estimate rather than a construction-specific finding, because reliable industry-specific measurements are limited.

How Time Theft Increases Construction Labor Costs

The cost shows up in more places than the paycheck:

  • Unworked hours: You pay for time when nobody was working, such as a 20-minute gap between a clock-in and the real start.
  • Extra overtime: A padded Monday can push a worker past 40 hours by Friday. You then pay the overtime rate for time that wasn’t worked.
  • Inflated phase costs: Padded hours spread across projects and job phases, so framing or drywall looks more expensive than it was.
  • Skewed bids: Wrong hours feed your job costing, and your next bid is built on those numbers.

How to Calculate Time Theft Costs per Worker and Job Site

To estimate time theft costs, calculate the value of the time lost per worker, then multiply it by the number of workers on the job site.

For the hourly wage, you can use USD 39.06, the June 2026 average hourly earnings for construction production and nonsupervisory workers, based on AGC and BLS data.

For example, if one worker loses 15 minutes a day over 250 working days, the annual cost is:

0.25 hours × USD 39.06 × 250 days = USD 2,441.25 per worker.

For a 20-person crew, that adds up to USD 48,825 per year at the same rate.

This estimate covers wages only. Payroll taxes, workers’ compensation, and other labor costs can increase the total. Use data from your own timesheet audits to estimate how much time your team loses and calculate a more accurate figure for each job site.

The Hidden Costs of Inaccurate Construction Time Records

Time records can serve as evidence in wage disputes and labor investigations. In fiscal year 2025, the Department of Labor’s (DOL) Wage and Hour Division recovered more than USD 259 million in back wages for nearly 177,000 workers, according to Construction Dive.

Under the Fair Labor Standards Act (FLSA), employees generally have two years to file a claim for unpaid wages, or three years for willful violations. They may also be entitled to liquidated damages equal to the unpaid wages.

Inaccurate records can also create problems in daily operations:

  • Payroll corrections: Office staff spend time fixing punches, tracking down missing information, and correcting pay.
  • Unreliable productivity data: Incomplete hours make it harder to compare crew performance and estimate labor needs for future projects.
  • Disputes: Workers, supervisors, and payroll staff may disagree about hours worked when records are incomplete.
  • Lower job profitability: Inaccurate labor costs distort project reports, making it harder to spot overruns and protect profit margins.

What Does Time Theft Look Like on Construction Sites?

Construction crews rarely follow the same routine from start to finish. Workers arrive at different times, move between job sites, collect materials, and sometimes rely on a foreman to record attendance. These conditions can make it easier to add unworked time to a timesheet or charge hours to the wrong project.

Buddy punching and clocking in for absent workers

A worker clocks in for a colleague who’s still on the road, or a foreman records attendance for the crew before everyone has arrived. On a large site, the discrepancy may go unnoticed until someone compares the time records with the daily attendance report. Repeated across a crew, these false punches can result in paying for hours nobody worked.

Early clock-ins and late clock-outs

A worker clocks in while still parking a truck or unloading tools, then starts work later. At the end of the shift, someone clocks out after packing up and leaving the site. These minutes can become costly when the same pattern repeats across a crew of 20 or 30 workers, especially on projects with tight labor budgets.

Extended breaks and unrecorded time away from the job

A worker leaves to collect supplies but doesn’t record the time away, or a lunch break runs longer than scheduled. If the timesheet shows continuous work, the project manager may charge those hours to the job even though the worker wasn’t on site. Employers should distinguish unauthorized time away from legitimate work errands and follow applicable rules on paid breaks and meal periods.

Inaccurate timesheets and manual time entry

A foreman reconstructs the crew’s hours at the end of the week, relying on memory instead of daily records. Start times get rounded, overtime is missed, or hours from different days are entered incorrectly. These mistakes may not be deliberate time theft, but they can still inflate labor costs and make payroll harder to verify.

Workers clocking in from the wrong jobsite

A worker assigned to one project clocks in at another site, or records time before reaching the assigned location. The hours may be charged to the wrong job, making one project’s labor costs look too high and another’s too low. Where sites have different pay rates, the mistake can also affect wages. Location records and job assignments can help supervisors check whether punches match the work performed.

Why Traditional Construction Time Tracking Fails to Prevent Time Theft

Traditional timekeeping methods leave gaps that are hard to spot on busy construction sites. Crews work across different locations, supervisors juggle several responsibilities, and records often depend on workers remembering to log their hours correctly. These gaps can make it difficult to verify attendance and catch time theft before it affects payroll.

  • Paper timesheets and manual punch corrections: Workers or foremen may fill in hours at the end of the day or week, relying on memory rather than records made at the time. Without a clear history of changes, it can be difficult to establish what was originally recorded and why an entry was corrected. 
  • Shared time clocks and PIN-based clock-ins: A worker can share a PIN with a colleague, allowing someone else to record their attendance. The system confirms that the correct code was entered, but not necessarily who used it. Facial recognition, such as the option available in our employee time clock software, adds a way to verify who is clocking in rather than relying on a shared code alone. Fareclock also supports PIN-only clock-ins when facial recognition is disabled. Administrators can configure PIN requirements based on their account settings. For setup instructions, see How to Use PIN-Only Clock In/Out.
  • Mobile time tracking without location verification: A mobile app makes it easier for workers to clock in from different locations, but without location checks, a punch may be recorded before the worker reaches the assigned site. This can leave supervisors unable to confirm whether the employee was where they were supposed to be.
  • Manual attendance checks across multiple sites: A superintendent may oversee several crews while managing deliveries, site issues, and schedule changes. Checking every arrival and departure personally is rarely practical. By the time a discrepancy comes to light, the supervisor may have to reconstruct the shift from incomplete records and memory. Tracking construction workers’ hours across multiple job sites requires a different approach than managing a single location.

How GPS-Verified Clock-Ins Help Prevent Construction Time Theft

GPS-verified clock-ins record a device’s location when a worker punches in. When combined with a geofence around a construction site, this helps employers check whether the punch was made within the permitted area.

  • Verify attendance at the correct construction site: Location data helps supervisors confirm that a clock-in occurred within the assigned site’s geofence, which is especially useful when crews move between projects.
  • Restrict clock-ins outside the jobsite boundary: Geofence settings can prevent workers from clocking in outside the permitted area, reducing the risk of punches being recorded from home or another location.
  • Flag unusual attendance patterns: Repeated punches from unexpected locations can alert supervisors to records that need further review. A location discrepancy isn’t proof of time theft, but it gives managers a reason to check the details.
  • Improve payroll and job costing records: Linking punches to the correct job helps companies track labor hours against the relevant project and cost codes. Fareclock supports job costing by job, phase, and cost code, helping contractors keep labor records organized across projects.

GPS has limits. It records where a device is when the punch occurs, but it doesn’t establish who is holding the phone or confirm that the worker continues working afterward. Combining location checks with identity verification, clear timekeeping rules, and regular reviews provides a stronger way to detect suspicious punches.

How to Calculate the ROI of GPS-Verified Construction Time Tracking

To estimate the return on investment (ROI), start with your current time theft costs, estimate how much of that cost a new system could prevent, and compare the potential savings with the cost of the software. Since actual results depend on the problems at your sites and how consistently the system is used, treat the recovery figures below as examples, not expected outcomes.

Step 1: Calculate current time theft costs.

Use this formula:

Time theft cost = Number of workers × Minutes lost per day ÷ 60 × Average hourly wage × Working days per year

For example, assume a contractor has 50 workers, each losing 15 minutes of paid time per day. Using an average hourly wage of USD 39.06 and 250 working days per year, the calculation is:

50 × 15 ÷ 60 × USD 39.06 × 250 = USD 122,062.50 per year.

The 15 minutes and 250 working days are assumptions, not measured results. Replace them with figures from your own time records and audits.

Step 2: Estimate potential labor cost savings.

The table shows how much of the estimated cost could be recovered at different rates. These are illustrative scenarios, not predictions of what GPS-verified clock-ins will save.

Illustrative recovery rate Potential annual savings
25% USD 30,515.63
50% USD 61,031.25
75% USD 91,546.88

GPS verification may help prevent punches from unauthorized locations, but it won’t eliminate every form of time theft. Your actual savings will depend on how much time is currently lost, which problems the system can address, and how consistently workers and supervisors follow the process.

Step 3: Compare savings with the cost of the system.

Subtract the annual software cost and other implementation expenses from the estimated labor cost savings.

Net annual benefit = Recovered labor costs − Annual software cost − Setup and training costs

Use a quote from your software provider and include the time required to train workers and supervisors. A payroll calculator can help you work out labor costs more precisely before running the comparison. To calculate ROI as a percentage, divide the net annual benefit by the total annual investment and multiply by 100.

How to Implement GPS Time Tracking on Construction Sites

A smooth rollout starts with clear rules, site-specific settings, and a simple process for handling exceptions. The steps for how to set up time tracking software for a construction company cover the full configuration process.

  • Set up geofences around construction sites. Set a boundary for each site that accounts for normal GPS variation. Geo-mapping tools can help define and visualize these zones. Test on site because buildings and indoor areas can affect location accuracy.
  • Establish clear clock-in and clock-out rules. Explain where and when workers should punch in and out, how to report missed punches, and how breaks and travel time are recorded.
  • Explain location tracking policies to workers. Tell workers what data is collected, when tracking occurs, and how the information is used. Check local notice and privacy requirements before rollout.
  • Review exceptions and correct inaccurate punches. Give workers a way to report location errors or missed punches. Require manager approval for corrections and keep a record of changes.
  • Review time records and labor costs across projects. Check missing punches before payroll, then compare hours by job, phase, and cost code to catch discrepancies and keep labor costs accurate.
  • Review real-time attendance status. Use an attendance overview to check which workers are clocked in or out across job sites. This can help supervisors identify unexpected attendance records and follow up before payroll processing.

How Fareclock Helps Construction Companies Reduce Time Theft

On construction sites, a few questionable punches can add up across crews, shifts, and projects. Our construction time and attendance software helps contractors verify attendance, review time records, and track labor hours by job, so they have better information to manage labor costs.

  • Keep clock-ins within approved job sites: Set geofences around construction sites to restrict where workers can punch in and out. This helps prevent punches from unauthorized locations and makes it easier to check whether recorded attendance matches site assignments.
  • Verify who is clocking in: Fareclock’s facial recognition checks a worker’s face at clock-in, while liveness detection helps distinguish a real person from a photo or video. This adds a layer of protection against buddy punching, when one worker clocks in for another. Learn more about whether workers can clock in using a photograph, or read How to Maximize Successful Face Recognition.
  • Check worker locations when needed: GPS data associated with punches helps supervisors review where clock-ins occurred. On our Premium plan, live GPS tracking and breadcrumb history provide additional location information for managing mobile crews.
  • Keep labor hours tied to the right project: Fareclock tracks time by job, phase, and cost code, supporting job costing by project and phase. Geofence-based job selection can help workers record hours against the correct project, giving managers more reliable labor cost data.
  • Review time records before payroll: Managers can review and correct timecards, then prepare payroll reports and exports. Fareclock also identifies edited and manually added punches, making it easier to review changes and see the original recorded time.
  • Monitor real-time attendance with Roll Call Summary: Fareclock’s Roll Call Summary Console provides a quick overview of which workers are currently clocked IN or OUT, with details such as department, device, address, labels, and payroll ID. This helps supervisors review attendance across construction sites and identify records that may need further investigation.
  • Check attendance from mobile devices: Admins can access the Worker List on mobile and filter workers by clock-in/out status, department, organizational unit, or job. This gives supervisors real-time attendance visibility while moving between job sites, without needing to access the desktop console.

    With Fareclock, contractors can bring attendance verification, timecard review, real-time attendance monitoring, and job costing into one workflow instead of relying on paper records and manual checks across sites.

    FAQ

    How much does time theft cost a construction company?

    The cost depends on how many workers are affected, how much time is lost, and the average hourly wage. For example, 50 workers losing 15 minutes a day at USD 39.06 per hour would cost USD 122,062.50 over 250 working days, before additional labor costs. Use your own time records to estimate the impact.

    Can GPS clock-ins prevent buddy punching?

    GPS can help confirm that a punch was recorded at the correct jobsite, but it cannot verify who is holding the phone. Combining location checks with facial recognition can help reduce buddy punching by checking the worker’s identity at clock-in.

    Is GPS tracking accurate enough for construction timekeeping?

    GPS can be useful for outdoor jobsite checks, but accuracy varies with the device and surroundings. Buildings and indoor areas can cause larger location errors, so test geofences on site and review punches that fall near the boundary.

    Can GPS time tracking verify that workers are at the correct jobsite?

    Yes. A system that uses geofences can check whether a punch falls within the designated jobsite boundary. Fareclock can also use geofences to select the relevant job automatically. Location readings can be less reliable in basements or near tall buildings, so supervisors should review questionable punches.

    Is GPS time tracking legal for construction employees?

    It depends on the applicable laws and how tracking is used. Employers should check state and local notice and privacy requirements, explain what location data they collect, and avoid tracking workers outside working hours.

    What is the best way to prevent time theft on construction sites?

    Use several safeguards together: verify worker identity, restrict clock-ins to approved jobsite areas, review unusual punches, document timecard changes, and approve records before payroll. Clear policies and consistent enforcement help make these controls effective.

    Can Construction Supervisors Monitor Worker Attendance in Real Time?

    Yes. Time and attendance software can give supervisors a current view of which employees are clocked in or out. Fareclock’s Roll Call Summary Console provides this information along with worker details, while the mobile Worker List allows admins to filter attendance by status, department, organizational unit, or job. This helps supervisors monitor crews across multiple sites and review unexpected attendance records more quickly.
