What Is a Mega Development Project?

A mega development project generally refers to a large-scale investment involving substantial capital expenditures, extensive infrastructure requirements, multiple stakeholders, and long-term economic impact.

Examples include:

• Large financing requirements
• Environmental obligations
• Infrastructure commitments
