Prefabrication is the practice of assembling components of a structure in a factory or other manufacturing site, and transporting complete assemblies or sub-assemblies to the construction site where the structure is to be located. Some researchers refer it to “various materials joined together to form a component of the final installation procedure“.
54-509: The Cross Bay Link ( Chinese : 將軍澳跨灣連接路 ) is a 1.8 km (1.1 mi) dual two-lane carriageway connecting the Tseung Kwan O Industrial Estate and LOHAS Park areas in Tseung Kwan O New Town , New Territories , Hong Kong with Tseung Kwan O-Lam Tin Tunnel . The mainstay of the link is the 1.0 km (0.62 mi) Tseung Kwan O Cross Bay Bridge ( Chinese : 將軍澳跨灣大橋 ),
108-588: A retronym applied to non-simplified character sets in the wake of widespread use of simplified characters. Traditional characters are commonly used in Taiwan , Hong Kong , and Macau , as well as in most overseas Chinese communities outside of Southeast Asia. As for non-Chinese languages written using Chinese characters, Japanese kanji include many simplified characters known as shinjitai standardized after World War II, sometimes distinct from their simplified Chinese counterparts . Korean hanja , still used to
162-509: A certain extent in South Korea , remain virtually identical to traditional characters, with variations between the two forms largely stylistic. There has historically been a debate on traditional and simplified Chinese characters . Because the simplifications are fairly systematic, it is possible to convert computer-encoded characters between the two sets, with the main issue being ambiguities in simplified representations resulting from
216-437: A fixed site. It is frequently used when fabrication of a section of a machine or any movable structure is shifted from the main manufacturing site to another location, and the section is supplied assembled and ready to fit. It is not generally used to refer to electrical or electronic components of a machine, or mechanical parts such as pumps, gearboxes and compressors which are usually supplied as separate items, but to sections of
270-474: A footpath, a cycle track, and the eastbound and westbound carriageways, with green strips separating each of them. Three observation platforms are also built along the footpath for pedestrians to appreciate the scenery of Tseung Kwan O. It is the first time that a cycle track is provided on a marine viaduct in Hong Kong, and with the bridge's completion, a 5 km (3.1 mi) loop cycleway encircling Junk Bay
324-507: A marine viaduct spanning Junk Bay incorporating a 200 m (660 ft) double-arch steel bridge. It is the first marine crossing in Hong Kong that combines the functions of carriageway, footway and cycle track in one bridge. The rest of the link is the bridge's at-grade approach named Wan O Road ( Chinese : 環澳路 ) south of LOHAS Park. The Tseung Kwan O Cross Bay Bridge links up the Tseung Kwan O Interchange, where it connects to
378-444: A specific part of the project or to the whole of it. The efficiency and speed in the execution times of these works offer that, for example, in the case of the educational sector, it is possible to execute the projects without the cessation of the operations of the educational facilities during the development of the same. Prefabrication saves engineering time on the construction site in civil engineering projects. This can be vital to
432-812: Is 産 (also the accepted form in Japan and Korea), while in Hong Kong, Macau and Taiwan the accepted form is 產 (also the accepted form in Vietnamese chữ Nôm ). The PRC tends to print material intended for people in Hong Kong, Macau and Taiwan, and overseas Chinese in traditional characters. For example, versions of the People's Daily are printed in traditional characters, and both People's Daily and Xinhua have traditional character versions of their website available, using Big5 encoding. Mainland companies selling products in Hong Kong, Macau and Taiwan use traditional characters in order to communicate with consumers;
486-521: Is formed. While the bridge is designed to withstand typhoons with wind speeds up to 320 km per hour, pedestrians and cyclists would be barred from accessing the bridge when the wind speed reaches 40 km/h. On 16 March 2009, Ove Arup & Partners Hong Kong Limited was employed to undertake the investigation and preliminary design of Cross Bay Link. The My vision of the Cross Bay Link Design Ideas Invitation event
540-436: Is often also referred to as off-site construction. These can be described as component (or sub-assembly) systems, panelised systems, volumetric systems, and modular systems. Below these categories different branches, or technologies are being developed. There are a vast number of different systems on the market which fall into these categories and with recent advances in digital design such as building information modeling (BIM),
594-434: Is the use of prefabricated concrete and prefabricated steel sections in structures where a particular part or form is repeated many times. It can be difficult to construct the formwork required to mould concrete components on site, and delivering wet concrete to the site before it starts to set requires precise time management. Pouring concrete sections in a factory brings the advantages of being able to re-use moulds and

#1732793582399648-400: Is used in various industries and construction sectors such as healthcare, retail, hospitality, education, and public administration, due to its many advantages and benefits over traditional on-site construction, such as reduced installation time and cost savings. Being used in single-story buildings as well as in multi-story projects and constructions. Providing the possibility of applying it to
702-493: The Chinese Commercial News , World News , and United Daily News all use traditional characters, as do some Hong Kong–based magazines such as Yazhou Zhoukan . The Philippine Chinese Daily uses simplified characters. DVDs are usually subtitled using traditional characters, influenced by media from Taiwan as well as by the two countries sharing the same DVD region , 3. With most having immigrated to
756-592: The Baixa district, was rebuilt by using prefabrication on an unprecedented scale. Under the guidance of Sebastião José de Carvalho e Melo, popularly known as the Marquis de Pombal , the most powerful royal minister of D. Jose I , a new Pombaline style of architecture and urban planning arose, which introduced early anti-seismic design features and innovative prefabricated construction methods, according to which large multistory buildings were entirely manufactured outside
810-456: The Kensiu language . Prefabrication The most commonly cited definition is by Goodier and Gibb in 2007, which described the process of manufacturing and preassembly of a certain number of building components, modules, and elements before their shipment and installation on construction sites. The term prefabrication also applies to the manufacturing of things other than structures at
864-640: The Shanghainese -language character U+20C8E 𠲎 CJK UNIFIED IDEOGRAPH-20C8E —a composition of 伐 with the ⼝ 'MOUTH' radical—used instead of the Standard Chinese 嗎 ; 吗 . Typefaces often use the initialism TC to signify the use of traditional Chinese characters, as well as SC for simplified Chinese characters . In addition, the Noto, Italy family of typefaces, for example, also provides separate fonts for
918-579: The Tseung Kwan O–Lam Tin Tunnel (TKOLTT), with Wan O Road outside LOHAS Park . At the western end of the bridge, vehicle may enter or leave the bridge either through the TKOLTT, or via the spur route of Tseung Lam Highway (of which the bridge is part of) connecting to Tiu Keng Leng and Tseung Kwan O Town Centre. At its eastern end, the bridge continues as the at-grade Wan O Road (codenamed Road D9 during its construction), which intersects with
972-555: The People's Republic of China, traditional Chinese characters are standardised according to the Table of Comparison between Standard, Traditional and Variant Chinese Characters . Dictionaries published in mainland China generally show both simplified and their traditional counterparts. There are differences between the accepted traditional forms in mainland China and elsewhere, for example the accepted traditional form of 产 in mainland China
1026-587: The United States during the second half of the 19th century, Chinese Americans have long used traditional characters. When not providing both, US public notices and signs in Chinese are generally written in traditional characters, more often than in simplified characters. In the past, traditional Chinese was most often encoded on computers using the Big5 standard, which favored traditional characters. However,
1080-456: The assembly of aircraft and spacecraft , with components such as wings and fuselage sections often being manufactured in different countries or states from the final assembly site. However, this is sometimes for political rather than commercial reasons, such as for Airbus . Off-site fabrication is a process that incorporates prefabrication and pre-assembly. The process involves the design and manufacture of units or modules, usually remote from
1134-426: The body of the machine which in the past were fabricated with the whole machine. Prefabricated parts of the body of the machine may be called 'sub-assemblies' to distinguish them from the other components. An example from house-building illustrates the process of prefabrication. The conventional method of building a house is to transport bricks , timber , cement , sand , steel and construction aggregate , etc. to
SECTION 20
#17327935823991188-466: The bridge are concrete bridges with concrete box girders. The design concept "Eternity Arch" was adopted for the main span. The two outward leaning arches, which resemble the infinity symbol (∞), is said to signify the vitality, boundless energy and vigour found in the vibrant town of Tseung Kwan O. The arches are illuminated by LED spotlights from 7pm to 9pm every evening. The bridge's deck, 34 m (112 ft) in width, carries (from north to south)
1242-652: The bridgeworks. The steel bridge components, including the main span, were prefabricated in Nantong , China before being delivered progressively to Hong Kong by sea. The main span was carried by a semi-submersible barge, and arrived at the works site on 16 February 2021 after an 8-day voyage. Along with the Tseung Kwan O-Lam Tin Tunnel, the Cross Bay Link opened to traffic at 8am on 11 December 2022. The two new roads were expected to reduce
1296-524: The city, transported in pieces and then assembled on site. The process, which lasted into the nineteenth century, lodged the city's residents in safe new structures unheard-of before the quake. Also in Portugal, the town of Vila Real de Santo António in the Algarve , founded on 30 December 1773, was quickly erected through the use of prefabricated materials en masse. The first of the prefabricated stones
1350-402: The concrete can be mixed on the spot without having to be transported to and pumped wet on a congested construction site. Prefabricating steel sections reduces on-site cutting and welding costs as well as the associated hazards. Prefabrication techniques are used in the construction of apartment blocks, and housing developments with repeated housing units. Prefabrication is an essential part of
1404-564: The cost of transporting prefabricated sections and lifting them into position as they will usually be larger, more fragile and more difficult to handle than the materials and components of which they are made. Prefabrication has been used since ancient times. For example, it is claimed that the world's oldest known engineered roadway , the Sweet Track constructed in England around 3800 BC , employed prefabricated timber sections brought to
1458-454: The detailed design and supervise the construction. In 2018, the HK$ 2.5 billion contract to construct the bridge was awarded to China Road and Bridge Corporation . Meinhardt Infrastructure & Environment Ltd. and Hewson Consulting were appointed as the designers for China Road and Bridge Corporation to provide alternative permanent works design, erection engineering and temporary works design for
1512-450: The final point of manufacture are assembled elsewhere instead, before being delivered for final assembly. The theory behind the method is that time and cost is saved if similar construction tasks can be grouped, and assembly line techniques can be employed in prefabrication at a location where skilled labour is available, while congestion at the assembly site, which wastes time, can be reduced. The method finds application particularly where
1566-428: The improved quality. However, tradition often favors building by hand in many countries, and the image of prefab as a "cheap" method only slows its adoption. However, current practice already allows the modifying the floor plan according to the customer's requirements and selecting the surfacing material, e.g. a personalized brick facade can be masoned even if the load-supporting elements are timber. Today, prefabrication
1620-751: The industrialization of construction. The quality of prefabricated housing units had increased to the point that they may not be distinguishable from traditionally built units to those that live in them. The technique is also used in office blocks, warehouses and factory buildings. Prefabricated steel and glass sections are widely used for the exterior of large buildings. Detached houses, cottages, log cabin, saunas, etc. are also sold with prefabricated elements. Prefabrication of modular wall elements allows building of complex thermal insulation , window frame components, etc. on an assembly line , which tends to improve quality over on-site construction of each individual wall or frame. Wood construction in particular benefits from
1674-493: The inverse is equally true as well. In digital media, many cultural phenomena imported from Hong Kong and Taiwan into mainland China, such as music videos, karaoke videos, subtitled movies, and subtitled dramas, use traditional Chinese characters. In Hong Kong and Macau , traditional characters were retained during the colonial period, while the mainland adopted simplified characters. Simplified characters are contemporaneously used to accommodate immigrants and tourists, often from

1728-480: The lightness of the panels reduced the cost of foundations and assembly on site. Coloured concrete grey and with flat roofs, prefab houses were uninsulated and cold and life in a prefab acquired a certain stigma, but some London prefabs were occupied for much longer than the projected 10 years. The Crystal Palace , erected in London in 1851, was a highly visible example of iron and glass prefabricated construction; it
1782-725: The mainland. The increasing use of simplified characters has led to concern among residents regarding protecting what they see as their local heritage. Taiwan has never adopted simplified characters. The use of simplified characters in government documents and educational settings is discouraged by the government of Taiwan. Nevertheless, with sufficient context simplified characters are likely to be successfully read by those used to traditional characters, especially given some previous exposure. Many simplified characters were previously variants that had long been in some use, with systematic stroke simplifications used in folk handwriting since antiquity. Traditional characters were recognized as
1836-682: The majority of Chinese text in mainland China are simplified characters , there is no legislation prohibiting the use of traditional Chinese characters, and often traditional Chinese characters remain in use for stylistic and commercial purposes, such as in shopfront displays and advertising. Traditional Chinese characters remain ubiquitous on buildings that predate the promulgation of the current simplification scheme, such as former government buildings, religious buildings, educational institutions, and historical monuments. Traditional Chinese characters continue to be used for ceremonial, cultural, scholarly/academic research, and artistic/decorative purposes. In
1890-983: The merging of previously distinct character forms. Many Chinese online newspapers allow users to switch between these character sets. Traditional characters are known by different names throughout the Chinese-speaking world. The government of Taiwan officially refers to traditional Chinese characters as 正體字 ; 正体字 ; zhèngtǐzì ; 'orthodox characters'. This term is also used outside Taiwan to distinguish standard characters, including both simplified, and traditional, from other variants and idiomatic characters . Users of traditional characters elsewhere, as well as those using simplified characters, call traditional characters 繁體字 ; 繁体字 ; fántǐzì ; 'complex characters', 老字 ; lǎozì ; 'old characters', or 全體字 ; 全体字 ; quántǐzì ; 'full characters' to distinguish them from simplified characters. Some argue that since traditional characters are often
1944-452: The middle of the 20th century, when various countries that use Chinese characters began standardizing simplified sets of characters, often with characters that existed before as well-known variants of the predominant forms. Simplified characters as codified by the People's Republic of China are predominantly used in mainland China , Malaysia, and Singapore. "Traditional" as such is
1998-501: The north-south artery Wan Po Road linking to Tseung Kwan O Industrial Estate . Unlike TKOLTT, the bridge is not part of Route 6 . The centrepiece of the bridge is the prefabricated double-arch steel bridge section in its middle. With a length of 200 m and a weight of 10,000 tonnes, the main span is the longest and heaviest steel arch bridge in Hong Kong. The main span has a maximum clearance of 160 m (520 ft) in width by 17 m (56 ft) in height. The remaining sections of
2052-677: The official script in Singapore until 1969, when the government officially adopted Simplified characters. Traditional characters still are widely used in contexts such as in baby and corporation names, advertisements, decorations, official documents and in newspapers. The Chinese Filipino community continues to be one of the most conservative in Southeast Asia regarding simplification. Although major public universities teach in simplified characters, many well-established Chinese schools still use traditional characters. Publications such as
2106-700: The original standard forms, they should not be called 'complex'. Conversely, there is a common objection to the description of traditional characters as 'standard', due to them not being used by a large population of Chinese speakers. Additionally, as the process of Chinese character creation often made many characters more elaborate over time, there is sometimes a hesitation to characterize them as 'traditional'. Some people refer to traditional characters as 'proper characters' ( 正字 ; zhèngzì or 正寫 ; zhèngxiě ) and to simplified characters as 簡筆字 ; 简笔字 ; jiǎnbǐzì ; 'simplified-stroke characters' or 減筆字 ; 减笔字 ; jiǎnbǐzì ; 'reduced-stroke characters', as
2160-522: The site rather than assembled on-site. Sinhalese kings of ancient Sri Lanka have used prefabricated buildings technology to erect giant structures, which dates back as far as 2000 years, where some sections were prepared separately and then fitted together, specially in the Kingdom of Anuradhapura and Polonnaruwa . After the great Lisbon earthquake of 1755 , the Portuguese capital, especially
2214-516: The site, and to construct the house on site from these materials. In prefabricated construction , only the foundations are constructed in this way, while sections of walls , floors and roof are prefabricated (assembled) in a factory (possibly with window and door frames included), transported to the site, lifted into place by a crane and bolted together. Prefabrication is used in the manufacture of ships , aircraft and all kinds of vehicles and machines where sections previously assembled at

2268-404: The structure is composed of repeating units or forms, or where multiple copies of the same basic structure are being constructed. Prefabrication avoids the need to transport so many skilled workers to the construction site, and other restricting conditions such as a lack of power, lack of water, exposure to harsh weather or a hazardous environment are avoided. Against these advantages must be weighed
2322-754: The success of projects such as bridges and avalanche galleries , where weather conditions may only allow brief periods of construction. Prefabricated bridge elements and systems offer bridge designers and contractors significant advantages in terms of construction time, safety, environmental impact, constructibility, and cost. Prefabrication can also help minimize the impact on traffic from bridge building. Additionally, small, commonly used structures such as concrete pylons are in most cases prefabricated. Radio towers for mobile phone and other services often consist of multiple prefabricated sections. Modern lattice towers and guyed masts are also commonly assembled of prefabricated elements. Prefabrication has become widely used in
2376-471: The task of integrating these different systems into a construction project is becoming increasingly a "digital" management proposition. The prefabricated construction market is booming. It is growing at an accelerated pace both in more established markets such as North America and Europe and in emerging economies such as the Asia-Pacific region (mainly China and India). Considerable growth is expected in
2430-636: The traditional character set used in Taiwan ( TC ) and the set used in Hong Kong ( HK ). Most Chinese-language webpages now use Unicode for their text. The World Wide Web Consortium (W3C) recommends the use of the language tag zh-Hant to specify webpage content written with traditional characters. In the Japanese writing system , kyujitai are traditional forms, which were simplified to create shinjitai for standardized Japanese use following World War II. Kyūjitai are mostly congruent with
2484-985: The traditional characters in Chinese, save for minor stylistic variation. Characters that are not included in the jōyō kanji list are generally recommended to be printed in their traditional forms, with a few exceptions. Additionally, there are kokuji , which are kanji wholly created in Japan, rather than originally being borrowed from China. In the Korean writing system , hanja —replaced almost entirely by hangul in South Korea and totally replaced in North Korea —are mostly identical with their traditional counterparts, save minor stylistic variations. As with Japanese, there are autochthonous hanja, known as gukja . Traditional Chinese characters are also used by non-Chinese ethnic groups. The Maniq people living in Thailand and Malaysia use Chinese characters to write
2538-523: The travelling time between LOHAS Park and Kwun Tong Town Centre by 20 minutes during the morning peak hours. District councillor Gary Fan claimed that although the bridge's design was similar to Nanning Yonghe Bridge in Guangxi, he believed it is not a direct copy. Civil Engineering and Development Department chief engineer Wong Wai Man claimed that there are thousands of bridges in the world that are over 200 m (220 yd) long, and as such, there
2592-518: The ubiquitous Unicode standard gives equal weight to simplified and traditional Chinese characters, and has become by far the most popular encoding for Chinese-language text. There are various input method editors (IMEs) available for the input of Chinese characters . Many characters, often dialectical variants, are encoded in Unicode but cannot be inputted using certain IMEs, with one example being
2646-587: The words for simplified and reduced are homophonous in Standard Chinese , both pronounced as jiǎn . The modern shapes of traditional Chinese characters first appeared with the emergence of the clerical script during the Han dynasty c. 200 BCE , with the sets of forms and norms more or less stable since the Southern and Northern dynasties period c. the 5th century . Although
2700-450: The work site, and the installation at the site to form the permanent works at the site. In its fullest sense, off-site fabrication requires a project strategy that will change the orientation of the project process from construction to manufacture to installation. Examples of off-site fabrication are wall panels for homes, wooden truss bridge spans, airport control stations . There are four main categories of off-site fabrication, which
2754-494: Was followed on a smaller scale by Oxford Rewley Road railway station . During World War II , prefabricated Cargo ships , designed to quickly replace ships sunk by Nazi U-boats became increasingly common. The most ubiquitous of these ships was the American Liberty ship , which reached production of over 2,000 units, averaging 3 per day. The most widely used form of prefabrication in building and civil engineering

In 19th century Australia a large number of prefabricated houses were imported from the United Kingdom. The method was widely used in the construction of prefabricated housing in the 20th century, such as in the United Kingdom as temporary housing for thousands of urban families "bombed out" during World War II . Assembling sections in factories saved time on-site and
