14×7 rotation and other field rotations: how to quote them
Updated on 22/10/2026
In the field, the job doesn't stop when the crew rests. On a 14×7 rotation each position works 14 days and rests 7, so to cover a position every day you need relief staff. That relief gets paid, and if it isn't in your price, it comes out of your margin.
The rotation factor
Factor = (work days + rest days) ÷ work days
| Rotation | Factor | What it means |
|---|---|---|
| 6×1 | 1.17 | 17% more staff to cover the day off |
| 7×7 | 2.00 | Two people per position |
| 14×7 | 1.50 | One and a half people per position |
| 20×10 | 1.50 | Same as 14×7, with longer shifts |
| 21×7 | 1.33 | One third more staff |
Example: a 6-person crew on 14×7
- Positions covered on site: 6
- People on payroll: 6 × 1.5 = 9
- If the real cost per person is S/ 4,500 per month, the crew costs S/ 40,500 per month, not S/ 27,000
On top of that, add everything that is also multiplied per person-day: meals, lodging, transportation to the site, PPE, medical exams, and SCTR.
MIVA Cost automatically applies the rotation factor to labor and per-person-day costs when you choose the project's rotation.
Frequently asked questions
Does the factor also apply to per diem?
Yes, to everything paid per person: per diem, PPE, medical exams, travel to and from the site. Not to equipment or materials.
What if the client pays per day worked?
Then your daily rate must include the cost of relief staff: the monthly cost of the full crew divided by the days you actually bill.
