Learning
Prepare the estimate basis alongside a cost estimate for an investment, design or procurement decision. Update it when scope maturity, quotations, quantities, price dates or commercial assumptions change enough to affect interpretation of the figure.
It explains what the estimate buys and how uncertain it is. Decision makers can compare alternatives on a consistent basis and avoid treating a preliminary allowance as a supported commitment.
The estimator prepares the basis with design, quantity, procurement and commercial contributors. An independent cost reviewer checks coherence; the sponsor or delegated manager decides use of the estimate under project governance.
Do not compare estimates with different tax, scope or price-date assumptions as though their totals measure the same thing; reconcile the bases first.
Illustrative example: an early estimate for a logistics building uses budget supplier quotations and concept quantities. The basis identifies excluded utility reinforcement and its uncertainty. The sponsor can then commission the missing utility assessment before treating the total as an investment approval basis.
