Civil megaprojects are large, complex ventures in civil engineering and construction that typically cost over $1 billion to construct. These projects generally have significant and long-lasting impacts on the economy, environment and society, and involve multiple public and private stakeholders. Typical civil megaprojects include infrastructure projects, such as highways, bridges, tunnels, airports, dams, power plants and public buildings, which require extensive planning, design, coordination and construction over an extended period of time.
