Audited planning profile
This shared quarterly profile applies a 3× editable baseline across 4 model periods to the garden project change model.
Use the absolute difference for budgeting and the percentage difference for comparing impact. Define a consistent allocation rule so shared usage is not counted twice. Check seasonality and any costs that occur only once per quarter.
Permits, local labor rates, material specifications, site conditions and professional engineering review are excluded.
Verify dimensions, specifications, waste factors and current supplier or contractor quotes.
