The construction industry is divided into three types;
Buildings Construction: includes contractors, usually called general contractors, who build residential, industrial, commercial, and other buildings.
Civil Construction: build sewers, roads, highways, bridges, tunnels, and other projects related to our Nation’s infrastructure.
Specialty Construction: Performs specialized activities related to all types of construction such as carpentry, painting, plumbing, and electrical work.
Construction usually is done or coordinated by general contractors or main contractors, who specialize in one type of construction such as residential or commercial building. They take full responsibility for the complete job, except for specified portions of the work that may be omitted from the main contract. Although main contractors may opt to do part of the works with their own workers, packages are usually subcontracted out to specialty contractors.
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.
As energy costs have risen, some companies are finding it necessary to build or renovate buildings that are not energy efficient. “Green construction” and Sustainable Architecture are areas that is increasingly popular and involves making buildings as environmentally friendly and energy efficient as possible by using more recyclable and earth-friendly products.
