Supplements are not a fight. They are an engineering reconciliation process between initial scope and field reality.
System Design: Build the File Like an Auditor Will Read It
Use one supplement package with five sections:
- Executive variance summary
- Line-item delta matrix
- Evidence index
- Permit/code support (where applicable)
- Updated estimate export and change log
The Delta Matrix Standard
Each variance row should include:
- Carrier line item and amount
- Requested line item and amount
- Net delta
- Evidence ID references
- Technical rationale in one sentence
This removes ambiguity and keeps the discussion objective.
Common Colorado-Specific Gap Patterns
- Permit-driven sequencing not reflected
- Access complexity under-modeled
- Accessory and collateral scope underrepresented
- Documentation for statutory/contractual compliance missing
Evidence Hierarchy (Strongest to Weakest)
- Timestamped field photos with slope labels
- Permit and inspection artifacts
- Manufacturer/code references relevant to installed system
- Narrative-only assertions
The package should rely on levels 1-3, not level 4.
Timing Strategy
- Submit supplement package quickly after initial scope receipt
- Batch related deltas in one cycle where possible
- Track carrier responses by line-item status
Status taxonomy
- Approved
- Partially approved
- Need more evidence
- Denied with reason code
Legal Context Without Overreaching
Colorado law prohibits unreasonable delay/denial for first-party claims and provides remedies in defined circumstances. Keep supplement communication technical and factual; avoid unsupported legal posturing.
Homeowner Governance Checklist
- Demand written rationale on denied deltas
- Keep all versions of estimates and correspondence
- Use one canonical “current scope” file at all times
- Reconcile paid amounts to approved scope monthly until closeout
