๐งฎ Metrics That Matter: ๐น Labor Productivity Ratio
Each edition, spotlight a key metric that affects jobsite performance or project health.
This weekโs focus: Labor Productivity Ratio (LPR)
๐ What is it?
LPR measures the efficiency of your crew by comparing earned labor hours (based on actual progress) to actual labor hours spent.
๐น Formula:Labor Productivity Ratio = Earned Hours รท Actual Hours
โ Why it matters:
A ratio above 1.0 means your team is ahead of schedule or more productive than planned.
A ratio below 1.0 indicates overruns and may signal delays or inefficiencies.
Tracking LPR helps identify high-performing teams, scope risks, and areas where workflow or manpower needs adjustment.
๐ ๏ธ Pro Tip:
Use LPR weekly for each crew or phase. Pair it with daily logs and earned value milestones to keep your project on track and your labor costs tight.
๐ Why It Matters
LPR > 1.0 โ You're ahead of schedule.
LPR = 1.0 โ You're on track.
LPR < 1.0 โ You're falling behind.
Itโs a quick way to check if your team is productive, where you're losing time, and how to fix it.
๐ ๏ธ Quick Tips
Use daily production logs to track earned hours.
Break LPR down by phase: rough-in, wire pull, fixtures, etc.
Pair it with delay notes โ material or RFI issues often explain dips.
๐งพ Simple Example
Task | Earned Hrs | Actual Hrs | LPR |
|---|---|---|---|
3/4" EMT Rough-In | 44 hrs | 40 hrs | 1.10 |
Feeder Pull | 20 hrs | 24 hrs | 0.83 |
๐ก Use LPR weekly to stay on track, coach your team, and forecast smarter.
