| Best use Complete one workbook per workflow. Use actual operating data where possible. If you cannot estimate the current cost of the problem, do not claim a future ROI yet. |

| Question | Your answer |

| What work are we changing? | |
| Who owns the outcome? | |
| What failure or delay are we trying to reduce? | |
| What measurable result should improve? | |
| What happens if we do nothing? | |
| Metric | Current value | Source |

| Monthly volume | | |
| Human hours per unit | | |
| Loaded labor cost/hour | | |
| Error/rework rate | | |
| Average delay | | |
| Revenue lost or delayed | | |
| Customer-service cost | | |
| Compliance/quality incidents | | |
| Cost component | Formula | Annual estimate |
|---|
| Direct labor | Volume × hours × loaded hourly cost | |
| Rework | Errors × average rework cost | |
| Delay | Delayed cases × economic cost of delay | |
| Lost opportunity | Qualified opportunities missed × expected contribution | |
| Other recurring cost | Licenses, contractors, manual handling | |
| Current-state cost Annual current-state cost = direct labor + rework + delay + lost opportunity + other recurring cost. |

| Contingency (10-20%) | | |
| Measure | Formula | Result |

| Annual gross benefit | Cost avoided + contribution gained | |
| Annual net benefit | Gross benefit – recurring AI cost | |
| Year-1 net benefit | Gross benefit – Year-1 total cost | |
| ROI % | Net benefit ÷ total cost × 100 | |
| Payback months | Initial investment ÷ monthly net benefit | |
| 3-year net value | 3-year benefit – 3-year total cost | |

| ☐ | Benefits are tied to a named owner | ____________________________ |
| ☐ | Baseline numbers came from operating evidence | ____________________________ |
| ☐ | Savings represent work actually eliminated or redeployed | ____________________________ |
| ☐ | Human review time is included | ____________________________ |
| ☐ | Integration and maintenance are included | ____________________________ |
| ☐ | Adoption below 100% is modeled | ____________________________ |
| ☐ | Failure/exception handling is costed | ____________________________ |
| ☐ | A simpler non-AI alternative was compared | ____________________________ |
| Score | Interpretation | Recommended action |
|---|
| 80-100 | Compelling | Fund a controlled pilot with explicit success thresholds. |
| 65-79 | Promising | Pilot narrowly; validate the largest assumptions first. |
| 50-64 | Marginal | Redesign the workflow or reduce solution cost before proceeding. |
| <50 | Weak | Do not implement yet. Fix the business case, process, or data first. |
| Catha principle AI should not be approved because it is interesting. It should be approved because the expected value exceeds the full cost, risk and management burden. |

Frequently asked questionsPractical questions construction owners ask.
Which construction workflows are good ROI candidates?
Estimating research, bid document review, project administration, customer and subcontractor follow-up, closeout, reporting and business-development research.
How do you calculate the current-state cost?
Annual current-state cost equals direct labor plus rework plus delay plus lost opportunity plus other recurring cost.
What if we cannot estimate what the problem costs today?
Then do not claim a future ROI yet. Complete one workbook per workflow and use actual operating data where possible.
