A recent study by PMC evaluated 10 construction robots used in real-world projects, measuring improvements in safety, accuracy, cost and schedule. Robotic tools outperformed traditional methods across nearly all metrics, showing major reductions in rework, improved task precision and significant time savings—especially in repetitive or hazardous tasks like layout, welding and painting.
KEY DATA POINTS
- Accuracy improvement range:
- 20–90% (mean: 55%)
- Rework reduction:
- >50% across most robots
- Time savings:
- up to 2.3 times faster execution
- 8 of 10 robots also reduced injury risk
- Human oversight remained necessary in 80% of cases
