Electronic working-time record for construction companies
Short answer
A construction company can comply with the electronic working-time record from each person's phone, with the location confirmed only at the moment of recording. The law asks for recording each person's start and end times; it does not ask for a wall-mounted time clock.
How work is done at a construction company
A construction company employs bricklayers, skilled workers, site supervisors and administrative staff, with site workdays from Monday to Saturday, in locations that change. That brings three challenges for measuring working time:
- Each job lasts a few months and then moves to a new place.
- Site staff come and go in stages.
- Paper pay sheets get lost.
What the law asks of construction companies
Since the 2026 reform, the Federal Labor Law requires recording electronically the start and end time of each worker's workday (article 132, section XXXIV). Failing to do so is fined 250 to 5,000 UMA. The STPS will define who it applies to and what exceptions there will be. The details are in the reform guide.
Work peaks. Overtime has a weekly cap: 9 hours at double time in 2027, with a maximum of 4 per day on no more than 4 days, and never more than 12 total hours in a day.
Hourly or temporary staff. They have the same working-hour limits and must also be recorded.
Work outside the premises. The time a person is at the company's disposal is working time, even if they are not at your facilities.
How to record working time at a construction company
- Register your team and their shifts.
- Each person clocks in from their phone where their shift begins.
- The location is captured only when clocking in; there is no tracking during the day.
- You see in one place who has already started, who is missing and where they clocked in.
Example. Each job site is added as a location. When it ends, it is closed and the staff move to the next one without installing anything.
Calculate your overtime
How to do the math by hand
Take a salary of $400 per day on a day shift. The ordinary hour is worth 400 ÷ 8 = $50. In 2027, with 11 overtime hours in the week, the first 9 are paid at double time (9 × $100 = $900) and the remaining 2 at triple time (2 × $150 = $300). Total: $1,200.
Common mistakes at a construction company
- Keeping attendance from memory or in a notebook.
- Recording the clock-in and forgetting the clock-out.
- Covering peaks only with overtime, until exceeding the weekly cap.
- Not recording temporary staff because they only come in for one day.
- Asking staff who work offsite to stop by the office just to clock in.
What to check every day and every week
Every day.
- Who did not record their clock-in or clock-out.
- Records made in unexpected places.
- Departures later than planned.
Every week.
- Each person's overtime against the weekly cap.
- Days when someone came close to 12 hours.
- Rest days that were actually taken.
How much an overtime hour costs: example in pesos
Suppose a daily wage of $450 on a day shift. The ordinary hourly rate is $56.25. One overtime hour at double time costs $112.50 and one at triple time, $168.75. If a person works 9 overtime hours in a week in 2027, that is $1,012.50 extra.
It is an example to show the calculation, not a reference wage for the sector.

Frequently asked questions
Does a construction company need to buy a time clock?
No. The law requires an electronic record of working time, not a device. An app on a phone complies.
What options are there for recording working time?
An app on each person's phone, a shared tablet or a clock connected to a system. All three comply if they generate an electronic record per person, with a start and an end time.
Can I ask for more overtime in peak season?
The weekly cap is not extended for the season. It helps to plan relief staff.
Does temporary staff also clock in?
Yes. Their record is kept even if they work only one day.
What happens when the STPS publishes its rules?
They will specify who the record applies to and its exceptions. It is worth checking them as soon as they appear in the Official Gazette of the Federation.
