Track construction spend against budget by phase—shell, MEP, and expansion—and by month. Connecting invested capital to returns helps keep the construction view and pro forma aligned.
Where budget tracking can break down
- One capex line: It can hide phased delivery, when power comes online in blocks rather than all at once.
- Separate files: Construction and returns may sit in different spreadsheets, allowing numbers to drift.
- No monthly view: Without invested-to-date alongside full build-out by month, timing is harder to review.
If the timing in the model differs from actual spending by quarters and millions, the IRR assumption may no longer match reality.
A practical tracking checklist
- By phase: Show budget, spent, and remaining for shell, MEP, and expansion.
- By month: Build an invested-capital view from the spend curve.
- Linked to returns: Use invested capital in the waterfall rather than a hand-typed number.
- Capture changes: Log each budget edit with before-and-after values and its impact on net profit.
