The Construction manufacturing is separated into three major segments. Constructions of buildings contractors, or general contractors, build residential, industrial, commercial, and other buildings. Construction usually is done or coordinated by general contractors, who specialize in one type of construction such as residential or commercial building, Specialty trade contractors usually do the work of only one trade, such as painting, carpentry, or electrical work, or of two or more closely related trades, such as plumbing and heating. Beyond fitting their work to that of the other trades, specialty trade contractors have no responsibility for the structure as a whole. They obtain orders for their work from general contractors, architects, or property owners. Repair work is almost always done on direct order from owners, occupants, architects, or rental agents.

Construction offers a great variety of career opportunities. People with many different talents and educational backgrounds—managers, clerical workers, engineers, truck drivers, trades workers, and construction helpers—find job opportunities in the construction industry. Construction trades workers are employed in a large variety of occupations that are involved in all aspects of the construction industry. Earnings in construction are higher than the average for all industries

Design, finance, and legal aspects overlap and interrelate. The design must be not only structurally sound and appropriate for the use and location, but must also be financially possible to build, and legal to use. The financial structure must accommodate the need for building the design provided, and must pay amounts that are legally owed. The legal structure must integrate the design into the surrounding legal framework, and enforces the financial consequences of the construction process.
