A construction company is a business entity that engages in the building, renovation or repair of structures and infrastructure. These companies often work on projects such as buildings, highways, bridges, tunnels, and other large-scale constructions. They may specialize in certain types of construction, such as residential, commercial, industrial, or civil engineering projects. Construction companies typically hire skilled workers, including architects, engineers, and tradespeople, to manage and complete their projects according to the specifications and within budget constraints.
