The hidden cost of paper timesheets in construction

What does a paper timesheet actually cost?

A paper timesheet costs the handling time it takes to turn handwriting into payroll, plus errors that do not appear on any bill. The sheet itself is cheap. The cost lands in the office and with the foremen, which is why it goes unmeasured.

The first three are real labor you pay for every week. The last three are exposure: they distort pay and job cost rather than add a line item. Keep them separate when you total them.

How much time does re-keying paper sheets take?

Re-keying takes however many minutes per sheet your office spends reading, entering and checking, multiplied by the number of sheets each week. The multiplier is what makes small per-sheet times add up: 25 workers means 25 sheets, every week, all year.

Time on the sheet itself varies a lot. A clean sheet with one job and clear times can take a couple of minutes. A sheet with crossed-out lines, three jobs and a note in the margin takes several. Time a handful of real sheets with a stopwatch rather than guessing, and use the average.

What do callbacks and foreman handling add?

Callbacks add time on both ends of the phone. When the office calls a foreman about a blank line, the office loses minutes finding the sheet and asking, and the foreman loses minutes on a call in the middle of running a crew, usually from memory days after the fact.

Foremen also spend time on sheets directly: handing them out, collecting them Friday, checking for gaps, and getting them to the office. That is skilled, higher-rate time. Count it at the foreman's loaded rate, not the office's.

Does rounding on paper cost you money or create risk?

Rounding can do either, because paper sheets usually round to whole or half hours and the direction depends on the person writing. Federal regulations accept rounding to the nearest 5 minutes, tenth or quarter hour, but only where it averages out so employees are paid for all the time they actually work (29 CFR 785.48).

Paper has no way to show whether your rounding averages out. If crews tend to write 6:30 for a 6:35 arrival and 2:30 for a 2:20 finish, the sheet pays 10 minutes that were not worked. If it runs the other way, you owe time that was worked. Either way you need a second record to know which. The worked example below treats rounding as an exposure to measure, not a savings.

What do timesheet disputes and storage cost?

A dispute costs the time two or three people spend reconstructing a day from a sheet that was written once and cannot be checked. The sheet is the whole record, so the argument is about what someone remembers.

Storage is smaller but real. The Department of Labor says payroll records are kept at least three years and time cards two (Fact Sheet 21). On paper that means boxes someone files, and someone later finds. State rules may be longer.

How do paper timesheets distort job costing?

They distort it by charging hours to whichever job was written first or last, so the labor on a job report reflects a recollection, not the work. The wage is the same either way. What is wrong is where the cost lands, which is why a job can look profitable on paper and lose money in the field.

This is the largest dollar exposure on paper and the hardest to see, because nothing is out of balance. Payroll ties out. The job cost report does not. See construction job costing for labor, and the calculator for unclear hours.

What does this look like in a worked example?

Take a 25-person contractor with four foremen on paper. Every number below is an assumption. Replace each one with your own, and treat the result as a template, not a benchmark.

How do you measure your own cost in one week?

Measure it with a stopwatch, a tally sheet and a second source of truth, for one pay period. You will need the three inputs the example above used, plus a check on rounding.

1. 1

   Time ten sheets

   Time how long it takes to read, enter and check each one, from a messy one to a clean one. Average them.

2. 2

   Tally callbacks

   Keep a mark every time the office calls a foreman about a sheet, with minutes on each side of the call.

3. 3

   Ask foremen for their handling time

   Have each foreman note the minutes spent collecting and checking sheets in one week.

4. 4

   Compare two weeks to a second record

   Match sheet start and end times against a gate log, a delivery ticket or a daily report for a sample of workers, and note the direction of any difference.

5. 5

   Sample job codes

   Pick three jobs and check where hours were charged against where the crew actually worked that week. Count the hours that differ.

• Rates used are loaded rates, not base wages. See how to calculate labor burden.
• Handling cost and exposure are totaled separately.
• The sample covers a normal week, not a short one.
• You have a date to do it again after any change.

When is paper still fine?

Paper is fine for a very small crew on a single site with a foreman who is always there and a weekly habit that never slips. Handling cost scales with sheets, so below five or six workers it is small. The exposure from rounding and job codes does not scale the same way, so check those even for a small crew.

If you are on paper and want a cleaner sheet, there is a construction timesheet template. If you are ready to move, how to switch from paper timesheets lays out the steps, and the construction time tracking guide compares the alternatives.

How ZeroBadge handles this

ZeroBadge removes the writing and the re-keying: the badge records the shift from power-on to power-off, every minute is classified on site, in transit or other and allocated to a jobsite, and weekly timesheets are built for review. The office still reviews exceptions and a manager still approves the week. See replace paper timesheets.
