Time and payroll

Choosing a time tracking method for construction crews

Updated November 4, 2026 · 4 min read

There is no single right way for crews to record time. A three-person remodeling crew, a 40-person site with a gate and a road crew moving every day need different things. What matters is that the method records exact hours, against the right job and code, and leaves a trail you can defend. This guide compares the options and covers the legal points that come with location and biometric data.

This is general information, not legal advice. Notice and consent rules vary by state and change often.

The options

Method	Works well when	Watch out for
Paper timecards	Very small crews, no devices	Filled in late, rounded, hard to read and to split by cost code
Foreman crew sheet (paper or app)	One person enters the crew's time; phones banned or crews small	Workers do not confirm their own hours; needs a sign-off to defend break claims
Individual mobile clock-in	Crews with phones, several sites	Personal-phone policy, data costs, notice laws, some workers less comfortable with apps
Kiosk or badge at the site trailer	Large sites with a gate	Hardware, power and signal; badges can be shared
Biometric clock (fingerprint or face)	Stopping one worker clocking in for another	Consent, notice and retention laws with heavy penalties in some states

Many contractors combine two: the foreman clocks the crew in on one phone, and workers who move between sites clock themselves.

Whatever the method, check these

Exact minutes, no rounding. It removes a whole class of wage claims. See What counts as hours worked.
Works without signal. Punches must be stored on the device with their real time and sent when signal returns. A method that fails in the basement will be worked around.
Job and cost code at the punch. Or allocated by the foreman the same day. See Tracking crew time by cost code.
Breaks recorded as taken. Especially in states with meal and rest period rules.
Corrections leave a trail. Every edit keeps the original punch, who changed it, when and why.

Location: GPS stamps and geofences

Location data helps answer "were they on site?" without a phone call. There are three levels, with rising privacy impact:

A location stamp at clock-in and clock-out. Records where the punch happened. Least intrusive and usually enough.
A geofence. Warns, or asks for a reason, when a punch is outside the job's boundary. Use it to flag punches for review rather than refuse them, and never to clock someone out automatically in a way that loses work time.
Continuous tracking during the shift. Raises the most notice and privacy questions, and is rarely needed for timekeeping.

Several states require written notice before employers use electronic monitoring or tracking. New Jersey requires written notice before using a tracking device on a vehicle an employee uses. New York requires notice of electronic monitoring at hiring, with an acknowledgment and a posted notice. Connecticut requires prior written notice of the types of monitoring. A safe practice everywhere: tell workers in writing what location data is collected and when (for example, only at clock events), and get an acknowledgment before you start.

Biometrics

Fingerprint and face clocks stop one worker clocking in for another, but they bring legal obligations. Illinois' Biometric Information Privacy Act requires written notice and a signed release before collecting biometric data, with damages of $1,000 per negligent and $5,000 per intentional or reckless violation, and has produced large class actions against employers using biometric time clocks. Illinois amended the law in 2024 to limit repeated claims, but exposure per worker remains. Colorado requires consent and a written biometric policy from July 2025, and Texas and Washington have their own notice and consent rules.

If you use biometrics, get legal advice first, choose a system with a documented retention and deletion policy, and collect written consent before the first scan. Often a photo at clock-in, which a supervisor can look at, gives enough assurance without biometric data.

An approval workflow that holds up

Daily: the foreman reviews the crew's hours, codes and breaks before leaving site.
At clock-out: each worker confirms their hours and whether they got their breaks. In states with break penalties this record is your evidence either way.
Weekly: the project manager or payroll approves the period before the payroll cutoff.
Missed punches: the worker asks for a correction, the supervisor approves it, and the request is kept.
After payroll runs: lock the period. Any later change is a dated adjustment, not an edit.

Moving crews off paper

Pilot with one willing foreman for two to four weeks before rolling out.
Run paper and the new method side by side for one pay period, so everyone can see the numbers agree.
Give notice and collect acknowledgments for location (and consent for biometrics) before go-live.
Decide on phones. Company devices or workers' own; some states, California among them, require employers to reimburse necessary business expenses, so check before relying on personal phones.
Train on site in ten minutes, and pay for the time.
Set a daily sign-off deadline and track late submissions before scaling up.
