Abrasive Blasting, Shot Peening & Surface Prep calculator
Blast Rework Cost Calculator
Rework after failed profile, contamination, missed coating window, or incomplete removal can erase margin quickly. This calculator helps quality and estimating teams put a dollar value on the area likely to be reblasted or reprocessed.
What this calculator does
- Estimate rework dollars from affected area, reblast/recoat cost per square foot, expected affected percentage, and inspection or remobilization cost.
- you need to quantify the cost exposure of rejected surface prep or a likely reblast area
- Returns expected rework exposure for rejected or suspect surface preparation.
Formula used
- Expected rework subtotal = potential rework area × reblast/recoat cost × expected affected area
- Total rework cost = expected rework subtotal + inspection/remobilization cost
Inputs explained
- Potential rework area: undefined
- Reblast/recoat cost: undefined
- Expected affected area: undefined
- Inspection/remobilization cost: undefined
How to use the result
- Use it during NCR review, customer negotiation, containment decisions, or quote risk allowance setting.
- It does not include liquidated damages, coating warranty exposure, schedule penalties, or root-cause corrective action unless added as fixed cost.
Common questions
- What belongs in reblast/recoat cost? Include labor, abrasive, equipment, coating touch-up if applicable, cleanup, and disposal that scale with reworked square footage.
- How do I set expected affected area? Use inspection findings, sampling confidence, or a conservative containment estimate.
- Should I include lost schedule time? Add schedule or remobilization costs to the fixed input if they are real costs for the job.
- How does the result help quality decisions? It shows whether broader inspection or preventive action is cheaper than risking repeated rework.
