CAPEX Planning

Building a defensible capital plan, budget envelope and approval package.

A defensible CAPEX plan states its estimate class and accuracy range, separates base cost from contingency and escalation, shows the cash-flow profile against milestones, and tests the case against volume, price and delay sensitivities. Class 5 concept estimates carry −30/+50% accuracy; Class 3 budget estimates −15/+25%; Class 1 control estimates −5/+10%. CAPEX planning converts strategy into a funded, phased, board-approvable programme: cost estimate class, contingency, phasing, cash-flow profile, sensitivity and the governance gates each tranche must pass.

What decides the outcome in capex planning

Estimate class declaration

Every number should state its class. Presenting a concept estimate as a budget is the single most common cause of approved projects overrunning.

Total installed cost, not equipment price

Include freight, duties, foundations, installation, integration, spares, training, commissioning and owner's costs.

Contingency and escalation separately

Contingency covers known unknowns inside scope; escalation covers price and currency movement over the delivery period.

Stage-gate release

Release capital in tranches tied to feasibility, tender, award and commissioning gates rather than in one approval.

CAPEX Planning — questions buyers ask

What should contingency be?

8–12% for a well-defined Class 3 estimate; 15–25% when the scope is still conceptual or the site is unfamiliar.

Which return metric should lead the approval?

NPV at the company's discount rate leads; IRR, discounted payback and DSCR support it. Simple payback alone hides the timing of cash flows.

How far ahead should a capital plan run?

Three to five years, reviewed annually, with year one at budget accuracy and later years at concept accuracy.
