construction, the techniques and industry involved in the assembly and erection of structures, primarily those used to provide shelter. Construction is an ancient human activity. It began with the purely functional need for a controlled environment to moderate the effects of climate.
Broadly, there are six types of construction projects: residential, commercial, institutional, mixed-use, industrial, and heavy civil. Urban planners often categorize projects based on their “end use” to ensure development projects meet the varying needs of the communities in which they are built.
