How overtime hours are identified and calculated in construction, and how company overtime rules work with attendance and payroll data.

Overtime is the hours a worker works beyond a defined threshold, paid at a higher rate. In construction, overtime is common, and getting it right matters because overtime hours multiply both the hours records and the pay calculations.

The first thing to understand is that overtime rules in Canada vary by province. Each province sets its own employment standards for daily and weekly overtime thresholds and overtime rates. What is overtime in one province may not be overtime in another, and the rules change over time.

Because the rules are provincial and changeable, this guide describes the concepts rather than prescribing specific numbers. A company should verify the current thresholds and rates that apply in its province with the official provincial employment standards source or a qualified professional.

The common pattern in Canadian overtime rules is a daily threshold and a weekly threshold. If a worker exceeds the daily threshold, the hours beyond it are overtime. If a worker exceeds the weekly threshold, the hours beyond it are also overtime. Some provinces also define special rules for double time beyond a higher threshold.

In FastBuild, overtime rules are configured at the company level in the company settings: the daily threshold, the weekly threshold, and the overtime rate multiplier. The same rules apply across every site, which keeps the calculation consistent.

Overtime hours are identified from the attendance record. Each work session has a start and end time, so daily hours are the sum of the sessions that day, and weekly hours are the sum across the week. When a daily total exceeds the daily threshold, the excess is overtime. When the weekly total exceeds the weekly threshold, the excess is overtime.

The calculation then applies the rate multiplier to the overtime hours: overtime pay is the overtime hours multiplied by the hourly rate multiplied by the multiplier. A multiplier of 1.5 is the common time-and-a-half pattern.

For payroll, the overtime hours appear in the pay period calculation alongside regular hours. The pay stub separates regular pay and overtime pay so the breakdown is visible.

Common mistakes in construction overtime include applying daily and weekly overtime inconsistently across sites, losing the weekly view because daily records are kept separately, and rounding hours in a way that quietly removes overtime. A single attendance record that preserves daily and weekly totals avoids all three.

The practical workflow is: set the company overtime rules once, let attendance produce the daily and weekly hours, review the overtime totals at the end of the week, and let the payroll calculation apply the rules to the pay period.
