Separate the budget components
Track construction work separately from design, surveys, permits, testing, temporary operations, furniture, technology, equipment, and other owner costs. Keep optional upgrades visible. A contractor’s proposal may be only one part of the owner’s total commitment.
What changes the construction cost
Two spaces of similar size can need very different amounts of work. Retaining an existing layout and usable finishes is a different scope from removing walls, changing restrooms or coordinating equipment and building-system alterations. Price the work the property actually needs before comparing a cost per square foot.
- Existing condition: demolition, repairs and concealed conditions can change the work required.
- Layout and systems: moving rooms or equipment can involve more than new finishes.
- Selections: the material, quantity, preparation and installation requirements belong together.
- Access and phasing: occupied areas, restricted deliveries and separate work releases affect the construction plan.
- Owner scope: furniture, technology, equipment and temporary operations may sit outside the contractor’s price.
Describe allowances and unresolved risk
An allowance should state the item, quantity or basis, installation assumptions, and how the final selection will be reconciled. Contingency is a planning reserve for uncertainty; it does not make undefined work disappear. List concealed-condition questions and decide which should be investigated before approval.
Connect decisions to the forecast
Record the budget effect of design changes, material selections, access restrictions, and owner purchases. Maintain separate views of approved commitments, actual invoices, pending changes, and remaining work. This avoids treating an unapproved option as either a firm cost or a saving.
- Who may approve a change?
- Which releases need owner or lender action?
- What decisions must be made before procurement?
