Infrastructure construction is a sector that deals with complex construction projects that include roads, highways, bridges, tunnels, railways, power plants, airports etc. Infrastructure construction is responsible for the construction of major structures that aren’t owned by a private owner—the structure ranges from dams, wastewater treatment centers to walkway construction projects. For this reason, infrastructure construction mainly falls under the sponsorship of the government or big corporations. Infrastructure construction is also known as heavy civil construction or civil engineering.
