Complete project budget
Hidden costs outside a contractor’s quote
A quote can be accurate and still be incomplete. Your real budget must include every cost required to reach a usable finished result.
The number that matters:everything required before, during and after the quoted work
Before construction starts
- Design, engineering, surveys or soil testing
- Permits, plan review and inspection fees
- Financing, deposits and insurance requirements
- Demolition, clearing, access or temporary protection
Work outside the contractor’s scope
- Electrical, plumbing, HVAC or utility connections
- Site preparation, drainage, grading or foundation corrections
- Material delivery, equipment rental and haul-off
- Owner-supplied fixtures, finishes or appliances
Costs created by the project
- Temporary housing, storage or portable services
- Repairs to landscaping, walls, flooring or driveways
- Final cleaning, testing, commissioning and punch-list work
- Change orders and discoveries behind walls or underground
Build a contingency without pretending it is free money
Set aside a separate contingency based on project uncertainty. Do not use it to make the base estimate look affordable. Track the known scope, unresolved items and contingency separately so you know why the number changes.
True project cost = quoted work + outside scope + owner purchases + contingency
