Construction is a broad term meaning the science and craft of constructing things, structures, systems or even people, and derives from Old French and Latin constructionis. In English it has come to mean anything that involves the building of something from raw materials. To build is the most general verb: to create, and the word construction is the technical meaning of this verb: what is made, the shape of the construction, its material, and so on.
The construction industry has come a long way since the time of the ancient Greeks and Romans. Before that time construction only included basic tools and equipment, such as hammer, chisel, saw, nail and plow. However, with the advent of the steel industry in Europe and America, the construction xay nha cap 4 industry expanded into complex technological equipment. There was a need to develop new kinds of equipment and techniques, as well as an increasing demand for skilled labor.
As a result, new construction technologies emerged, such as the use of welded pipes and beams to make buildings more stable and earthquake resistant. The development of steel in Europe and the United States led to the development of concrete, which is used today to build many structures. There have been developments in other fields as well, such as in the field of civil engineering, but these can not be classified as part of the construction business.
Today, there are numerous ways in which a company can work in the construction industry. Most companies work in residential projects, such as houses and apartment buildings, schools, offices, hospitals and businesses. Others also work in commercial construction, such as building stadiums, water and sewer facilities, parks, amusement parks and airports. There are also companies that specialize in designing structures, like for example, the ones used in schools or government buildings. These companies often design office buildings, dormitories, restaurants, office buildings and shopping malls.
Building projects also come with an array of specialists, including those that specialize in materials handling, safety, building maintenance, electrical and plumbing. Other specialized professionals include those that help to plan and execute the project, such as architects and engineers. There are also specialists who can oversee construction, such as those who are responsible for planning the site for the project, designing it and providing technical assistance to subcontractors.
Many companies are smaller and run by just one person, or even a handful of people. These companies specialize in construction, while others run multiple construction sites. One of the biggest construction companies is that of the International Brotherhood of Teamsters, who represents over 1.5 million construction workers around the world.
