👷 Crew Productivity Calculator

Calculate crew productivity, daily output, and labor hours needed for construction tasks.

Quick Formula​

Daily Output​

Daily Output = Crew Size × Hours per Day × Productivity Rate

Labor Hours Needed​

Labor Hours = Total Work ÷ Daily Output

Crew Days Needed​

Crew Days = Labor Hours ÷ (Crew Size × Hours per Day)

Common Productivity Rates​

Concrete Work​

TaskRateUnit
Formwork15-25 sq ft/hrPer worker
Rebar100-200 lbs/hrPer worker
Pour/finish20-40 sq ft/hrPer worker

Framing​

TaskRateUnit

Roof framing30-60 sq ft/hrPer worker
Sheathing100-150 sq ft/hrPer worker

Common Calculations​

Example 1: Concrete Slab​

Work: 1,000 sq ft slab Crew: 3 workers Hours: 8 hours/day Productivity: 25 sq ft/hr per worker

Calculation:

  • Daily output: 3 × 8 × 25 = 600 sq ft/day
  • Days needed: 1,000 ÷ 600 = 1.67 days (2 days)

Example 2: Framing​

Work: 2,000 sq ft wall framing Crew: 4 workers Hours: 8 hours/day Productivity: 75 sq ft/hr per worker

Calculation:

  • Daily output: 4 × 8 × 75 = 2,400 sq ft/day
  • Days needed: 2,000 ÷ 2,400 = 0.83 days (under 1 day)
