Building Renovation Cost Estimate
This is a practical guide to building a cost estimate for a building renovation project — a forecast of the money required to complete the work, adapted to the realities of renovating or refurbishing an existing building.
What a Cost Estimate is
A cost estimate is a forecast of the money required to complete the work. For the full concept and how it works in general, see Cost Estimation. On a building renovation project it plays the same role, tuned to this kind of work.
Why it matters for a Building Renovation project
Building Renovation projects live or die on renovating or refurbishing an existing building. A well-built cost estimate gives the team a shared, explicit reference for exactly that — reducing ambiguity, aligning stakeholders, and making problems visible early enough to act. Skipping it, or doing it generically, is how building renovation projects drift into avoidable delay and cost.
What to include
- Labour costs
- Material/equipment costs
- Indirect costs
- Contingency
- Estimate basis and assumptions
Building Renovation-specific considerations
Tailor the cost estimate to the risks that most often derail building renovation projects:
- Unknown existing conditions
- Occupied-site working
- Scope changes on discovery
Example
On a real building renovation project, the cost estimate would be shaped by renovating or refurbishing an existing building. In particular, it should explicitly account for the project’s biggest risks — unknown existing conditions, occupied-site working, scope changes on discovery — rather than treating them as afterthoughts.
