Construction
Construction is a general term meaning the art and science to form objects, systems, or organizations,"Construction" def. 1.a. 1.b. and 1.c. ''Oxford English Dictionary'' Second Edition on CD-ROM (v. 4.0) Oxford University Press 2009 and comes from Latin ''constructio'' (from ''com-'' "together" and ''struere'' "to pile up") and Old French ''construction''. 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.

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 some ...

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 ...

Crane (machine)
A crane is a type of machine, generally equipped with a hoist (device), hoist rope, wire ropes or chains, and Sheave (mechanical), 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 ...

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 equipmen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ... [...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 ...

Demolition
Demolition (also known as razing, cartage, and wrecking) is the science and engineering in safely and efficiently tearing down of buildings and other artificial structures. Demolition contrasts with deconstruction, which involves taking a building apart while carefully preserving valuable elements for reuse purposes. For small buildings, such as houses, that are only two or three stories high, demolition is a rather simple process. The building is pulled down either manually or mechanically using large hydraulic equipment: elevated work platforms, cranes, excavators or bulldozers. Larger buildings may require the use of a wrecking ball, a heavy weight on a cable that is swung by a crane into the side of the buildings. Wrecking balls are especially effective against masonry, but are less easily controlled and often less efficient than other methods. Newer methods may use rotational hydraulic shears and silenced rock-breakers attached to excavators to cut or break through ...

Building
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, monument, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the :Human habitats, human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 tra ...

Infrastructure
Infrastructure is the set of facilities and systems that serve a country, city, or other area, and encompasses the services and facilities necessary for its economy, households and firms to function. Infrastructure is composed of public and private physical structures such as roads, railways, bridges, tunnels, water supply, sewerage, sewers, electrical grids, and telecommunications (including Internet access, Internet connectivity and Broadband, broadband access). In general, infrastructure has been defined as "the physical components of interrelated systems providing Commodity, commodities and services essential to enable, sustain, or enhance societal quality of life, living conditions" and maintain the surrounding environment. Especially in light of the massive societal transformations needed to Climate change mitigation, mitigate and Climate change adaptation, adapt to climate change, contemporary infrastructure conversations frequently focus on sustainable development and gre ...

Old French
Old French (, , ; Modern French: ) was the language spoken in most of the northern half of France from approximately the 8th to the 14th centuries. Rather than a unified language, Old French was a linkage of Romance dialects, mutually intelligible yet diverse, spoken in the northern half of France. These dialects came to be collectively known as the , contrasting with the in the south of France. The mid-14th century witnessed the emergence of Middle French, the language of the French Renaissance in the Île de France region; this dialect was a predecessor to Modern French. Other dialects of Old French evolved themselves into modern forms ( Poitevin-Saintongeais, Gallo, Norman, Picard, Walloon, etc.), each with its own linguistic features and history. The region where Old French was spoken natively roughly extended to the northern half of the Kingdom of France and its vassals (including parts of the Angevin Empire, which during the 12th century remained under Anglo-No ...
