Abrasive Blasting, Shot Peening & Surface Prep calculator
Blast Operator Labor Cost Calculator
Operator labor includes more than trigger time: setup, masking checks, hose moves, pot tending, cleanup, PPE, and inspection support all affect job cost. This calculator gives estimators a direct labor dollar value for blasting or peening work.
What this calculator does
- Estimate direct labor cost from blast hours, labor rate, hands-on percentage, and setup or PPE time cost.
- you need direct labor dollars for a blast quote, route step, or post-job variance review
- Returns the labor dollars assigned to the blast or peening operation.
Formula used
- Direct labor subtotal = planned labor hours × burdened labor rate × hands-on blast allocation
- Blast labor cost = direct labor subtotal + setup/PPE allowance
Inputs explained
- Planned labor hours: undefined
- Burdened labor rate: undefined
- Hands-on blast allocation: undefined
- Setup/PPE allowance: undefined
How to use the result
- Use it for quotes, router standards, overtime decisions, and variance checks after a job closes.
- It does not model learning curves, crew imbalance, weather downtime, or standby time unless you include them in hours or setup allowance.
Common questions
- Should the labor rate be burdened? For quoting, use a burdened rate that includes payroll taxes, benefits, supervision, and shop overhead if that is your estimating standard.
- What is hands-on allocation? It is the percent of paid hours that should be charged to this blast operation rather than waiting, moving, or other work.
- Can I use this for shot peening? Yes, if the hours and rate reflect the peening cell, operator certification, and inspection support.
- How does this connect to cost per square foot? Use the labor result as one component of the variable or fixed cost stack in the cost per square foot calculator.
