How to calculate

Enter the work quantity in the same units as the production rate (for example CY and CY/hour/person, or LF and LF/hour/person). Enter how many people are on the crew. The result is wall-clock hours and total man-hours.

Formula

Crew production = rate per person × crew size. Hours = quantity ÷ crew production. Man-hours = hours × crew size, which also equals quantity ÷ rate per person.

Common use cases

  • Trenching labor
  • Paving crew hours
  • Checking a production assumption
  • Man-hour budgets

Worked example

Example: 200 units, 5/hr/person, 4 people

  1. 1. Crew production

    5 × 4 = 20 units/hr

  2. 2. Hours

    200 ÷ 20 = 10 hr

FAQ

Does this include weather or mobilization?

No. It is quantity ÷ production only. Add weather, access, and setup on the schedule separately.

What production rate should I use?

Use a measured rate from a similar crew and condition, or a bid-item historical rate. Do not use a catalog rate if the site is tighter or wetter.
