Rule: +15% pre-margin cost for each additional active phase
This premium accounts for the increased complexity, coordination, and mobilization costs when performing multiple cleaning phases on a project.
How It Works:
| Active Phases | Premium Calculation | Total Multiplier | Cost Impact |
|---|---|---|---|
| 1 phase (any single phase) | No premium | 1.00× | Base cost |
| 2 phases (e.g., Rough + Final) | +15% × 1 | 1.15× | +15% |
| 3 phases (Rough + Final + Fluff) | +15% × 2 | 1.30× | +30% |
Formula:
Multi-Phase Multiplier = 1.0 + (0.15 × (number_of_phases - 1))
Why This Premium Exists:
- Multiple mobilizations – Crew and equipment must come to site multiple times
- Project management overhead – Coordinating with GC for multiple phase schedules
- Quality control – Each phase requires inspection and sign-off
- Storage/staging – May need to maintain supplies on-site between phases
- Scheduling complexity – Working around other trades between phases
- Administrative burden – Multiple invoices, documentation, walkthroughs
- Risk factor – More opportunities for delays, damage, or rework
Real-World Examples:
Scenario 1: Final Clean Only (1 phase)
- 10,000 ft² office
- Labor cost: $5,000
- No premium = $5,000 total labor
Scenario 2: Rough + Final (2 phases)
- Same 10,000 ft² office
- Base labor: $5,000
- +15% premium = $5,000 × 1.15 = $5,750 total labor
Scenario 3: Rough + Final + Fluff (3 phases)
- Same 10,000 ft² office
- Base labor: $5,000
- +30% premium = $5,000 × 1.30 = $6,500 total labor
How It Interacts with Phase Weights:
The premium is applied after the phase weights calculate base hours:
- First: Calculate hours based on phase weights (30%/50%/20%, etc.)
- Then: Apply the multi-phase premium to the total cost
- Finally: Add margin on top
Important Notes:
- This is pre-margin – applied before profit margins (Market-Win/Lean/Profit-Heavy)
- The premium is locked – cannot be changed without product approval
- It ensures profitability when managing the complexity of multi-phase projects
- This is separate from “passes” (doing the same phase multiple times)
The 15% per additional phase reflects the real operational cost of returning to a job site multiple times and coordinating with construction schedules.
