How Concrete Placement Time Estimator Works?
To estimate placement time, the Concrete Placement Time Estimator divides the job volume by the placement rate you enter and adds setup and rodding time. The process takes 4 steps.
Enter the volume
Type the volume in cubic yards (yd³) or cubic meters (m³), or the tubes.
Enter the rate
Type how fast the crew places concrete, such as 1 yd³ per hour with a drum mixer.
Add per-pier time
Enter minutes per pier for moving, rodding and leveling.
Read the time
The tool shows total hours and minutes per pier, and checks the total against the 90-minute ready-mix discharge window.
Concrete Placement Time Estimator Formula
The Concrete Placement Time Estimator uses volume ÷ rate.
Pour time
T = V ÷ R + n × t_pierR rate, n piers, t_pier per-pier time.
Per pier
T_pier = T ÷ nAverage time per pier.
Truck window
T ≤ 90 min from batchingASTM C94 sets a common 90-minute limit.
Worked example: 8 piers at 12 in × 48 in, 0.98 yd³, chute at 15 yd³/h, 4 min per pier
- Pour = 0.98 ÷ 15 × 60 = 4.1 min
- Moving and rodding = 8 × 4 = 32 min
- T = 36 min, inside the 90-minute window
Concrete Placement Time Estimator Conversion Table
The placement time conversion table lists pour time for 8 piers at 12 in × 48 in with 10% waste (0.98 yd³, 0.75 m³) at 5 placement rates, before per-pier moving time.
| Method | Rate | Pour time | Per pier |
|---|---|---|---|
| Hand mix, wheelbarrow | 0.5 yd³/h | 123 min | 15.4 min |
| Drum mixer, 2-person crew | 1.0 yd³/h | 61 min | 7.7 min |
| Drum mixer, 3-person crew | 1.5 yd³/h | 41 min | 5.1 min |
| Ready-mix chute | 15.0 yd³/h | 4 min | 0.5 min |
| Ready-mix with pump | 30.0 yd³/h | 2 min | 0.3 min |
Rates are sample inputs. Crew size, access and weather change them.
What is Concrete Placement Time Estimator?
A Concrete Placement Time Estimator is a scheduling tool that calculates how long a crew needs to pour and rod Sonotube piers from an entered placement rate.
Time limits apply to concrete. Ready-mix must be placed within a set window after batching, and hand-mixed batches start to stiffen within an hour. The estimator checks the pour plan against those limits and shows the time per pier.
The tool helps decide crew size: a third worker on a drum mixer job can cut pour time by a third or more.
What are the uses of Concrete Placement Time Estimator?
There are 4 main uses of the Concrete Placement Time Estimator.
Truck scheduling
Contractors book a truck and confirm the discharge window.
Crew sizing
Supervisors add workers to meet a deadline.
Day planning
Owners plan digging and pouring on separate days.
Weather windows
Crews fit the pour before rain or heat.
