To construct is the verb: the act of building, and the noun is construction: how something is built, the nature of its structure. In its most widely used context, construction covers the processes involved in delivering buildings, infrastructure, industrial facilities and associated activities through to the end of their life. It typically starts with planning, financing, and design, and continues until the asset is built and ready for use; construction also covers repairs and maintenance work, any works to expand, extend and improve the asset, and its eventual demolition, dismantling or decommissioning.

Hut (dwelling)
A hut is a small dwelling, which may be constructed of various local materials. Huts are a type of vernacular architecture because they are built of readily available materials such as wood, snow, ice, stone, grass, palm leaves, branches, hides, fabric, or mud using techniques passed down through the generations. The construction of a hut is generally less complex than that of a house (durable, well-built dwelling) but more so than that of a shelter (place of refuge or safety) such as a tent and is used as temporary or seasonal shelter or as a permanent dwelling in some indigenous societies.Oxford English Dictionary Second Edition on CD-ROM (v. 4.0) © Oxford University Press 2009 Huts exist in practically all nomadic cultures. Some huts are transportable and can stand most conditions of weather. Word The term is often employed by people who consider non-western style homes in tropical and sub-tropical areas to be crude or primitive, but often the designs are based on t ...

Fast-track Construction
Fast-track building construction is construction industry jargon for a project delivery strategy to start construction before the design is complete. The purpose is to shorten the time to completion. Benefits Shorter schedules are desirable for reasons that vary with building owners. A shorter schedule may reduce a manufacturer's time-to-market, a school district's need to reduce overcrowding or simply provide a new home for a family sooner. Shorter schedules may also reduce the cost of construction financing and reduce overhead costs for the design and construction organizations. Shorter schedules may also reduce the impact of inflation during construction. The fast-tracking of the project is therefore achieved through the integration of design and construction phases. Fast-Track is more difficult to manage than the traditional design–bid–build process. It requires detailed knowledge of the process, effective planning, integrity and close coordination among the organizations ...

Bulldozer
A bulldozer or dozer (also called a crawler) is a large, motorized machine equipped with a metal blade to the front for pushing material: soil, sand, snow, rubble, or rock during construction work. It travels most commonly on continuous tracks, though specialized models riding on large off-road tires are also produced. Its most popular accessory is a ripper, a large hook-like device mounted singly or in multiples in the rear to loosen dense materials. Bulldozers are used heavily in large and small scale construction, road building, minings and quarrying, on farms, in heavy industry factories, and in military applications in both peace and wartime. The word "bulldozer" refers only to a motorized unit fitted with a blade designed for pushing. The word is sometimes used inaccurately for other heavy equipment such as a front-end loader designed for carrying rather than pushing material. Description Typically, bulldozers are large and powerful tracked heavy equipment. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Excavator
Excavators are heavy construction equipment consisting of a boom, dipper (or stick), bucket and cab on a rotating platform known as the "house". The house sits atop an undercarriage with tracks or wheels. They are a natural progression from the steam shovels and often mistakenly called power shovels. All movement and functions of a hydraulic excavator are accomplished through the use of hydraulic fluid, with hydraulic cylinders and hydraulic motors. Due to the linear actuation of hydraulic cylinders, their mode of operation is fundamentally different from cable-operated excavators which use winches and steel ropes to accomplish the movements. Terminology Excavators are also called diggers, JCBs (a proprietary name, in an example of a generic trademark), mechanical shovels, or 360-degree excavators (sometimes abbreviated simply to "360"). Tracked excavators are sometimes called "trackhoes" by analogy to the backhoe. In the UK and Ireland, wheeled excavators are sometim ...

Crane (machine)
A crane is a type of machine, generally equipped with a hoist rope, wire ropes or chains, and sheaves, that can be used both to lift and lower materials and to move them horizontally. It is mainly used for lifting heavy objects and transporting them to other places. The device uses one or more simple machines to create mechanical advantage and thus move loads beyond the normal capability of a human. Cranes are commonly employed in transportation for the loading and unloading of freight, in construction for the movement of materials, and in manufacturing for the assembling of heavy equipment. The first known crane machine was the shaduf, a water-lifting device that was invented in ancient Mesopotamia (modern Iraq) and then appeared in ancient Egyptian technology. Construction cranes later appeared in ancient Greece, where they were powered by men or animals (such as donkeys), and used for the construction of buildings. Larger cranes were later developed in the Roman Empire, e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guild
A guild ( ) is an association of artisans and merchants who oversee the practice of their craft/trade in a particular area. The earliest types of guild formed as organizations of tradesmen belonging to a professional association. They sometimes depended on grants of letters patent from a monarch or other ruler to enforce the flow of trade to their self-employed members, and to retain ownership of tools and the supply of materials, but were mostly regulated by the city government. A lasting legacy of traditional guilds are the guildhalls constructed and used as guild meeting-places. Guild members found guilty of cheating the public would be fined or banned from the guild. Typically the key "privilege" was that only guild members were allowed to sell their goods or practice their skill within the city. There might be controls on minimum or maximum prices, hours of trading, numbers of apprentices, and many other things. These rules reduced free competition, but sometimes mainta ...

Middle Ages
In the history of Europe, the Middle Ages or medieval period lasted approximately from the late 5th to the late 15th centuries, similar to the post-classical period of global history. It began with the fall of the Western Roman Empire and transitioned into the Renaissance and the Age of Discovery. The Middle Ages is the middle period of the three traditional divisions of Western history: classical antiquity, the medieval period, and the modern period. The medieval period is itself subdivided into the Early, High, and Late Middle Ages. Population decline, counterurbanisation, the collapse of centralized authority, invasions, and mass migrations of tribes, which had begun in late antiquity, continued into the Early Middle Ages. The large-scale movements of the Migration Period, including various Germanic peoples, formed new kingdoms in what remained of the Western Roman Empire. In the 7th century, North Africa and the Middle East—most recently part of the Eastern Ro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Slavery
Slavery and enslavement are both the state and the condition of being a slave—someone forbidden to quit one's service for an enslaver, and who is treated by the enslaver as property. Slavery typically involves slaves being made to perform some form of work while also having their location or residence dictated by the enslaver. Many historical cases of enslavement occurred as a result of breaking the law, becoming indebted, or suffering a military defeat; other forms of slavery were instituted along demographic lines such as race. Slaves may be kept in bondage for life or for a fixed period of time, after which they would be granted freedom. Although slavery is usually involuntary and involves coercion, there are also cases where people voluntarily enter into slavery to pay a debt or earn money due to poverty. In the course of human history, slavery was a typical feature of civilization, and was legal in most societies, but it is now outlawed in most countries of the w ...

Carpentry
Carpentry is a skilled trade and a craft in which the primary work performed is the cutting, shaping and installation of building materials during the construction of buildings, ships, timber bridges, concrete formwork, etc. Carpenters traditionally worked with natural wood and did rougher work such as framing, but today many other materials are also used and sometimes the finer trades of cabinetmaking and furniture building are considered carpentry. In the United States, 98.5% of carpenters are male, and it was the fourth most male-dominated occupation in the country in 1999. In 2006 in the United States, there were about 1.5 million carpentry positions. Carpenters are usually the first tradesmen on a job and the last to leave. Carpenters normally framed post-and-beam buildings until the end of the 19th century; now this old-fashioned carpentry is called timber framing. Carpenters learn this trade by being employed through an apprenticeship training—normally 4 years—an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bricklayer
A bricklayer, which is related to but different from a mason, is a craftsman and tradesman who lays bricks to construct brickwork. The terms also refer to personnel who use blocks to construct blockwork walls and other forms of masonry. In British and Australian English, a bricklayer is colloquially known as a "brickie". A stone mason is one who lays any combination of stones, cinder blocks, and bricks in construction of building walls and other works. Bricklaying is a part of masonry. Bricklaying may also be enjoyed as a hobby. For example, the former British Prime Minister Winston Churchill did bricklaying as a hobby. Bricklayers occasionally enter competitions where both speed and accuracy are judged. The largest is the "Spec-Mix Bricklayer 500" held annually in Las Vegas, Nevada, USA. Required training Bricklaying and masonry are ancient professions that even centuries later require modern training. Bricklayers usually go through a formal apprenticeship which includ ...
