Assumptions and exclusions
- Prepared for early budgeting and option screening from limited project definition.
- The area is treated as a declared planning parameter; detailed measurement is not part of this sample.
- External works, preliminaries, professional fees, and risk are shown as separate planning allowances.
- Rates and allowances are sample planning figures and must be refreshed for project location, date, scope, procurement route, and market conditions.
- This sample does not replace a developed elemental estimate, trade-led BOQ, live market pricing, or construction contract pricing.
