History of Building Construction
Building construction is an ancient human activity. It developed with the wholly practical need for a controlled environment to moderate the effects of climate. Built shelters were one means by which people were able to adjust themselves to a great variety of weather conditions and become a worldwide species.
Human abodes were initially very simple and probably lasted only a few days or months. Over time, however, even temporary buildings evolved into such highly refined forms as the igloo. Over time more durable structures began to arise, particularly after the beginning of agriculture, when people began to remain in one place for long periods. The early dwellings, but eventually other functions, such as food storage and ceremony, were housed in separate buildings. Some structures began to have symbolic as well as functional value, denoting the start of the difference between architecture and building.
The history of building is marked by several trends. One is the developing durability of the materials used. Early construction materials were flimsy, such as leaves, branches, and animal hides. Later, more hardy natural materials—eg clay, stone, and timber—and, finally, synthetic materials—such as brick, concrete, metals, and plastics—were used. Another is a quest for buildings of ever greater height and span; this was made possible by the development of stronger materials and by knowledge of how materials act and how to use them to greater advantage. Another major trend involves the degree of control placed over the interior environment of buildings: increasingly precise regulation of air temperature, light and sound levels, humidity, odours, air speed, and other elements which affect human comfort has been made possible. Yet another element is the change in energy available to the building process, starting with human muscle power and moving toward the powerful machinery used today.
The present state of building construction is intricate. There is a wide range of building products and systems which are aimed specifically at groups of building types or markets. The design process for buildings is highly organised and uses research establishments which study material properties and performance, code officials who adopt and enforce safety standards, and design professionals who determine user needs and design a building to meet those needs. The construction process is also well organised; it includes the manufacturers of building products and systems, the craftsmen who create them on the construction site, the contractors who hire and coordinate the work of the craftsmen, and consultants who specialise in such areas as building management, quality control, and insurance.
Building construction today is an important part of modern culture, a manifestation of its diversity and complexity and a measure of its control of natural forces, which can produce a widely varied built environment to provide for the diverse needs of people. This article first traces the history of building construction, then surveys its development at the present time.
