How Sonotube Labor Cost Estimator Works?
To estimate labor, the Sonotube Labor Cost Estimator multiplies hours per pier for each task by the pier count and the crew rate. The process takes 4 steps.
Enter task hours
Type labor hours per pier for digging, setting forms, rebar, pouring and cleanup.
Enter the pier count
Type how many piers the job has.
Enter crew rates
Type the hourly rate per worker, or a blended crew rate.
Read labor cost
The tool shows total hours, crew days and labor cost per task and per pier.
Sonotube Labor Cost Estimator Formula
The Sonotube Labor Cost Estimator uses hours × rate.
Task hours
Hᵢ = n × hᵢhᵢ person-hours per pier.
Labor cost
L = Σ Hᵢ × rr is the hourly rate.
Crew days
Days = Σ Hᵢ ÷ (crew size × 8)8-hour days.
Worked example: 8 piers, 2.83 person-hours per pier, $45 per hour, 2-person crew
- H = 8 × 2.83 = 22.6 person-hours
- L = 22.6 × $45 = $1,018.80
- Days = 22.6 ÷ 16 = 1.4 crew days
Sonotube Labor Cost Estimator Conversion Table
The labor conversion table lists sample person-hours per pier for 6 tasks and the cost for 8 piers at $45 per hour.
| Task | Hours per pier | Hours for 8 | Cost for 8 |
|---|---|---|---|
| Layout and staking | 0.25 h | 2.0 h | $90.00 |
| Digging (auger) | 0.75 h | 6.0 h | $270.00 |
| Gravel and tube setting | 0.50 h | 4.0 h | $180.00 |
| Rebar and bracing | 0.33 h | 2.6 h | $118.80 |
| Mixing and pouring | 0.75 h | 6.0 h | $270.00 |
| Anchors and cleanup | 0.25 h | 2.0 h | $90.00 |
| Total | 2.83 h | 22.6 h | $1,018.80 |
Task hours are sample inputs. Rocky soil, hand digging and long carries raise them.
What is Sonotube Labor Cost Estimator?
A Sonotube Labor Cost Estimator is a labor tool that applies entered hours and crew rates to the digging, forming and pouring work of a pier job.
Labor often costs more than materials on small pier jobs. Hours vary with soil, access and equipment: a powered auger digs a 12 in hole in minutes, while hand digging in clay takes an hour. The estimator takes your hours, so the result matches your site.
Splitting labor by task shows where time goes and which task a rental machine would shorten.
