# Build Operate Transfer (BOT) Model
## What is BOT?
BOT is a Public-Private Partnership (PPP) framework where a private company:
1. Builds the infrastructure (design, finance, construct)
2. Operates it during a concession period (recovering investment + earning profit)
3. Transfers ownership back to the government after the concession period ends
## Key Features
| Feature | Description |
|---|---|
| Private Sector Involvement | Private company handles design, financing, construction, and operation |
| Full Project Lifecycle | Private sector manages from inception through to operation |
| Ownership Transfer | After concession period, asset reverts to government |
| Risk Transfer | Financial and operational risks shift to private sector during concession |
| Infrastructure Development | Enables governments to undertake more projects using private capital |
| User Levy Principle | Tolls/user fees are charged to fund the project and generate returns |
## User Levy Principle (Important for Costing)
User charges are set so that:
- They reflect the benefits each user derives from the infrastructure
- Social costs = User benefits (equitable pricing)
- Optimal usage is encouraged and resources are efficiently allocated
## Applicability
BOT is suitable for:
- Large-scale infrastructure with substantial capital requirement (highways, bridges, airports, power plants, water treatment plants)
- Projects needing long-term operation and maintenance
- Sectors where private expertise adds significant value
## Government's Continuing Role
Despite private sector operation, the government:
- Maintains regulatory oversight
- Ensures compliance with laws and public interest
- Remains the ultimate owner of the asset
> BOT is one form of PPP — both parties collaborate toward a common public development goal.
