The dynamic façade of Jeddah Tower, however, creates an infinite timing differential (whereas Burj Khalifa is limited by the number of steps) in air pressure exertion in any one particular direction, thus creating
852-575: A collection of related dialects that constitute the precursor of Arabic, first emerged during the Iron Age . Previously, the earliest attestation of Old Arabic was thought to be a single 1st century CE inscription in Sabaic script at Qaryat al-Faw , in southern present-day Saudi Arabia. However, this inscription does not participate in several of the key innovations of the Arabic language group, such as

The Balkan languages, including Albanian, Greek , Serbo-Croatian, and Bulgarian , have also acquired many words of Arabic origin, mainly through direct contact with Ottoman Turkish . Arabic has influenced languages across the globe throughout its history, especially languages where Islam is the predominant religion and in countries that were conquered by Muslims. The most markedly influenced languages are Persian , Turkish , Hindustani ( Hindi and Urdu ), Kashmiri , Kurdish , Bosnian , Kazakh , Bengali , Malay ( Indonesian and Malaysian ), Maldivian , Pashto , Punjabi , Albanian , Armenian , Azerbaijani , Sicilian, Spanish, Greek, Bulgarian, Tagalog , Sindhi , Odia , Hebrew and African languages such as Hausa , Amharic , Tigrinya , Somali , Tamazight , and Swahili .

Weidlinger Associates was a U.S.-based structural engineering firm that designed and rehabilitated buildings, bridges, and infrastructure and provided special services in applied science, forensics, and physical security. The merger created two new entities: CORE Lab - a sister internal group to CORE studio - that focuses on the long-term development of internal methods, capabilities and products to evaluate new business opportunities; and TTWiiN,
1988-703: A millennium before the modern period . Early lexicographers ( لُغَوِيُّون lughawiyyūn ) sought to explain words in the Quran that were unfamiliar or had a particular contextual meaning, and to identify words of non-Arabic origin that appear in the Quran. They gathered shawāhid ( شَوَاهِد 'instances of attested usage') from poetry and the speech of the Arabs—particularly the Bedouin ʾaʿrāb [ ar ] {{main other| ( أَعْراب ) who were perceived to speak

On the northwestern frontier of Arabia, various languages known to scholars as Thamudic B , Thamudic D, Safaitic , and Hismaic are attested. The last two share important isoglosses with later forms of Arabic, leading scholars to theorize that Safaitic and Hismaic are early forms of Arabic and that they should be considered Old Arabic . Linguists generally believe that "Old Arabic",
2840-470: A single language, despite mutual incomprehensibility among differing spoken versions. From a linguistic standpoint, it is often said that the various spoken varieties of Arabic differ among each other collectively about as much as the Romance languages . This is an apt comparison in a number of ways. The period of divergence from a single spoken form is similar—perhaps 1500 years for Arabic, 2000 years for

The foundation is similar to that of the Burj Khalifa, but larger; it is expected to average around 4.5 m (15 ft) deep with a concrete pad of area around 7,500 m (81,000 sq ft). The concrete must have low permeability to keep out corrosive salt water from the Red Sea. Its depth and size are also considered to be an indicator of what the tower's final height will be. The piles will be up to 200 m (660 ft) deep and

The issue of diglossia between spoken and written language is a complicating factor: A single written form, differing sharply from any of the spoken varieties learned natively, unites several sometimes divergent spoken forms. For political reasons, Arabs mostly assert that they all speak

Additionally, a very big core size is required in very tall buildings to support the structure as well as to house the large number of elevators needed . The core size consumes a significant amount of the space on the lower and middle floors. One of the ways Jeddah Tower attempts to overcome these problems is with its smooth, sloped-exterior design, which, although more expensive to build, offers superior aerodynamic performance over "stepped" designs such as

The ISO assigns language codes to 32 varieties of Arabic , including its standard form of Literary Arabic, known as Modern Standard Arabic , which is derived from Classical Arabic . This distinction exists primarily among Western linguists; Arabic speakers themselves generally do not distinguish between Modern Standard Arabic and Classical Arabic, but rather refer to both as al-ʿarabiyyatu l-fuṣḥā ( اَلعَرَبِيَّةُ ٱلْفُصْحَىٰ "the eloquent Arabic") or simply al-fuṣḥā ( اَلْفُصْحَىٰ ).

In 1999, SpectralFlex was developed to serve the growing field of medical therapeutics, and in 2002, Weidlinger created the FLEX Template System, for modeling and simulation of structural components of civilian structures subjected to bomb blasts. 2001—World Trade Center collapse (New York, New York): In
9940-412: The Jeddah Economic City plot is nearly isolated from the current urban core of Jeddah, no land tracts of such size were available closer to the city. Northward is generally considered the direction in which the city will spread in the future. The primary designer of Jeddah Tower is Chicago-based architect Adrian Smith of Adrian Smith + Gordon Gill Architecture (AS + GG), the same architect who designed
10082-399: The Jeddah Tower employs a similar Y-shaped, triangular footprint which promotes stability and increases window views, as well as a tapering form, with the sheer height and wind being the biggest structural design challenge. The smooth, sloped façade of Jeddah Tower particularly induces a beneficial phenomenon known as "wind vortex shedding." Normally when wind swirls around the leeward side of
10224-412: The Middle East and North Africa have become a badge of sophistication and modernity and ... feigning, or asserting, weakness or lack of facility in Arabic is sometimes paraded as a sign of status, class, and perversely, even education through a mélange of code-switching practises." Arabic has been taught worldwide in many elementary and secondary schools, especially Muslim schools. Universities around
10366-503: The Middle East, particularly Saudi Arabia, and that three shifts will work around the clock to expedite the process. Construction costs have also declined since the global financial crisis. The 23 hectares (57 acres) area around Jeddah Tower will contain public space and a shopping mall, as well as other residential and commercial developments, and be known as the Jeddah Tower Water Front District, of which,
10508-487: The Mile-High Tower design had been approved at that height and that the building would cost almost US$ 30 billion (SR112.5 billion). This design was going to be drastically larger than the current design, with a floor area of 3,530,316 m (38,000,000 sq ft), and would have used futuristic wind-aversion and energy-producing technology for sustainability. It and the surrounding city would have had
10650-690: The Qur'an is referred to by linguists as "Quranic Arabic", as distinct from its codification soon thereafter into " Classical Arabic ". In late pre-Islamic times, a transdialectal and transcommunal variety of Arabic emerged in the Hejaz , which continued living its parallel life after literary Arabic had been institutionally standardized in the 2nd and 3rd century of the Hijra , most strongly in Judeo-Christian texts, keeping alive ancient features eliminated from
10792-576: The Romance languages. Also, while it is comprehensible to people from the Maghreb , a linguistically innovative variety such as Moroccan Arabic is essentially incomprehensible to Arabs from the Mashriq , much as French is incomprehensible to Spanish or Italian speakers but relatively easily learned by them. This suggests that the spoken varieties may linguistically be considered separate languages. With
10934-460: The TTG Group to Thornton Tomasetti in 1999. 1980s-1990s—FLEX code introduced: The FLEX code was first developed by Weidlinger in the early 1980s to support Nuclear Test Ban Treaty monitoring. Its name is derived from its primary focus, performing ”fast large explicit’ time-domain dynamic simulations, and from its versatility and speed in modeling unusually large structures. In the early 1990s,
11076-457: The US$ 7.2 billion (SR27.1 billion) new airport terminal under construction at King Abdulaziz (Jeddah) International Airport , that will complement the Jeddah Economic City as well as develop Saudi Arabia, which has been likened to a Third World country with crumbling infrastructure and widespread disasters, including severe flooding, such as the flash floods in early 2011 that damaged 90% of
11218-513: The ability to accommodate 80,000 residents and one million visitors, according to RIA Novosti . Adrian Smith denied that he was a part of any of the earlier designs, which had been purported in the media. One source even corrected its article and clarified the misunderstanding. In early August 2011, the Binladin Group was chosen as the main construction contractor with the signing of an SR4.6 billion ( US$ 1.23 billion ) contract, which
11360-418: The area cast doubt over whether the proposed location could support a skyscraper of the proposed one-mile (1,600 metres, 5,250 ft) height, and MEED reported that the project had been scaled back, making it "up to 500 metres (1,640 ft) shorter." Work on the foundation was scheduled to begin towards the end of 2012. Statements that construction would soon begin were made starting in 2008. In August 2011,
11502-528: The building services engineering consultants. On 2 August 2011, it was publicly announced by Kingdom Holding, the investment company, that a contract had been signed by Saudi Binladin Group (SBG), that construction was going to start soon, and that the tower was expected to take 63 months to complete. While the official construction estimate is five years and three months (63 months), others calculate that it will take significantly longer, over seven years, based on
11644-474: The building. Jeddah Tower will be oriented such that no façade directly faces the sun; it will also use the condensate water from the air conditioning system for irrigation and other purposes throughout the building. The building will have a total of 59 elevators, five of which will be double-deck elevators , as well as 12 escalators. The elevators are made by the Finnish company Kone . It will also have
11786-453: The contract. Jeddah Economic Company is a closed joint stock company (PJSC) formed in 2009 as a financial entity for Jeddah Tower and Jeddah Economic City. It is made up primarily of financiers (stakeholders) Kingdom Holding Company (33.35%), Abrar Holding Company (33.35%), which is owned by Samaual Bakhsh and businessman Abdulrahman Hassan Sharbatly (16.67%), as well as the tower's own contractor, Saudi Binladin Group (16.63%). JEC's assets have
11928-574: The conversion of Semitic mimation to nunation in the singular. It is best reassessed as a separate language on the Central Semitic dialect continuum. It was also thought that Old Arabic coexisted alongside—and then gradually displaced— epigraphic Ancient North Arabian (ANA), which was theorized to have been the regional tongue for many centuries. ANA, despite its name, was considered a very distinct language, and mutually unintelligible, from "Arabic". Scholars named its variant dialects after
12070-577: The core. This, along with the highly integrated steel frame and shear walls , is also intended to prevent catastrophic failure of the structure in the event of a terrorist attack. Traditionally, the space consumed by elevators was considered to make a building become increasingly less profitable past 80 floors or so. More recently, it has been the advent of truly mixed-use design such as Shanghai Tower and Burj Khalifa, as well as improved building technology, that have outdated this rule of thumb, which generally applied to single use buildings. Like Burj Khalifa,
12212-409: The country. According to Saudi officials, about 900 new homes are needed a day to meet the demand of the rapidly growing population, which has nearly quadrupled in the past four decades. Just as the Jeddah Tower will complement the Jeddah Economic City development that will be built around it, there are many infrastructure and revitalisation projects underway and planned throughout Saudi Arabia, such as
12354-434: The design of the proposed 3,000–4,700 car underground parking garage that will be located near, but not under the tower to prevent terrorism. Langan also designed the tower's foundation, which has to be able to support the tower despite the less than optimal subsurface conditions, such as soft rock and permeable coral, which could cause the piles to settle. Thornton Tomasetti has provided the structural engineering for two of
12496-465: The duration of Burj Khalifa's construction, which was over six years (with the help of CQC Department). Besix Group (Belgian Six Construct), which constructed the Burj Khalifa, was previously considered for the contract, but did not win, partially because SBG invested in Jeddah Economic Company (JEC), contributing SR1.5 billion (US$ 400 million) towards the development of the project. Besix admitted in 2010 that they expected Binladin Group to win
12638-522: The effects of blast loadings. Their methods led to early and continuing use of computers in advanced analysis and design. 1956—Lev Zetlin starts Lev Zetlin Associates: After earning a doctoral degree from New York’s Cornell University, Lev Zetlin decided to start his own company, Lev Zetlin Associates (LZA). 1960—Charlie Thornton joins LZA: Charlie Thornton, who earned master’s and doctoral degrees from New York University and authored
12780-587: The emergence of Central Semitic languages, particularly in grammar. Innovations of the Central Semitic languages—all maintained in Arabic—include: There are several features which Classical Arabic, the modern Arabic varieties, as well as the Safaitic and Hismaic inscriptions share which are unattested in any other Central Semitic language variety, including the Dadanitic and Taymanitic languages of
12922-479: The eve of financial collapse. The developers' theory is that the international attention gained through large developments and having the world's tallest building will incur gentrification of the country and even be a financial success in the long run. Architect Adrian Smith, the designer of the tower, states, "...this tower symbolizes the Kingdom as an important global business and cultural leader, and demonstrates
13064-728: The eve of the conquests: Northern and Central (Al-Jallad 2009). The modern dialects emerged from a new contact situation produced following the conquests. Instead of the emergence of a single or multiple koines, the dialects contain several sedimentary layers of borrowed and areal features, which they absorbed at different points in their linguistic histories. According to Veersteegh and Bickerton, colloquial Arabic dialects arose from pidginized Arabic formed from contact between Arabs and conquered peoples. Pidginization and subsequent creolization among Arabs and arabized peoples could explain relative morphological and phonological simplicity of vernacular Arabic compared to Classical and MSA. In around
13206-607: The fact that they participate in the innovations common to all forms of Arabic. The earliest attestation of continuous Arabic text in an ancestor of the modern Arabic script are three lines of poetry by a man named Garm(')allāhe found in En Avdat, Israel , and dated to around 125 CE. This is followed by the Namara inscription , an epitaph of the Lakhmid king Imru' al-Qays bar 'Amro, dating to 328 CE, found at Namaraa, Syria. From
13348-420: The firm conducted damage assessment in three states related to structural and architectural integrity, HVAC, electrical, plumbing and fire protection equipment and systems. Included in the investigations were high-rise office and residential facilities, and other retail, rail, aviation and government facilities. 2015—Thornton Tomasetti and Weidlinger merge: Thornton Tomasetti and Weidlinger Associates announced
13490-408: The foundation, to be constructed by Bauer in 2013, calls for 270 bored piles up to 110 m (360 ft) deep, which have to be installed into the difficult ground conditions. Some materials needed for the structure are 500,000 m (18,000,000 cu ft) of concrete and 80,000 t (79,000 long tons; 88,000 short tons) of steel. In March and April 2011, several news agencies reported that
13632-510: The fourth most useful language for business, after English, Mandarin Chinese , and French. Arabic is written with the Arabic alphabet , an abjad script that is written from right to left . Arabic is usually classified as a Central Semitic language . Linguists still differ as to the best classification of Semitic language sub-groups. The Semitic languages changed between Proto-Semitic and
13774-425: The highest observation deck in the world, to which high speed elevators will travel at up to 10 metres (33 feet) per second (36 km/h or 22 mph) in both directions. They must also be efficient so the cables are not unbearably heavy. Jeddah Tower will have three sky lobbies where elevator transfers can be made, and no elevator will go from the bottom to the highest occupied floor. To overcome elevator issues,
13916-545: The iconic Jeddah Tower project. The team will be providing project, commercial, and design management for the Jeddah Tower development. CEO of JEC, Waleed Abduljaleel Batterjee said that the reason Mace was hired is to use the same team that worked for The Shard in London. On the other hand, EC Harris also has a long list of projects in the region including the Grand Millenium Al-Wahda Hotel, Abu Dhabi 's largest hotel complex. On 29 April 2013, news
14058-597: The inclusion of new words into their published standard dictionaries. They also publish old and historical Arabic manuscripts. In 1997, a bureau of Arabization standardization was added to the Educational, Cultural, and Scientific Organization of the Arab League . These academies and organizations have worked toward the Arabization of the sciences, creating terms in Arabic to describe new concepts, toward
14200-464: The inference that Jeddah Tower will have over 200 floors. The tower will also feature a large, roughly 30 m (98 ft) diameter outdoor balcony, known as the sky terrace, on one side of the building for private use by the penthouse floor at level 157; it is not the observation deck. It was originally intended to be a helipad , but it was revealed to be an unsuitable landing environment by helicopter pilots. The lower air density, exacerbated by
14342-468: The kingdom's economic and cultural stature in the world community," said Talal Al Maiman, a board member of both Kingdom Holding Company and Jeddah Economic Company. The project's primary proponent, Prince Al-Waleed said, "Building this tower in Jeddah sends a financial and economic message that should not be ignored. It has a political depth to it to tell the world that we Saudis invest in our country." It
14484-613: The language. Software and books with tapes are an important part of Arabic learning, as many of Arabic learners may live in places where there are no academic or Arabic language school classes available. Radio series of Arabic language classes are also provided from some radio stations. A number of websites on the Internet provide online classes for all levels as a means of distance education; most teach Modern Standard Arabic, but some teach regional varieties from numerous countries. The tradition of Arabic lexicography extended for about
14626-604: The late 6th century AD, a relatively uniform intertribal "poetic koine" distinct from the spoken vernaculars developed based on the Bedouin dialects of Najd , probably in connection with the court of al-Ḥīra . During the first Islamic century, the majority of Arabic poets and Arabic-writing persons spoke Arabic as their mother tongue. Their texts, although mainly preserved in far later manuscripts, contain traces of non-standardized Classical Arabic elements in morphology and syntax. Abu al-Aswad al-Du'ali ( c. 603 –689)
14768-647: The latest technology in sustainable irrigation. The supply of water to irrigate the green space would be collected through rainwater. On 21 September 2012, it was announced that financing for the Jeddah Tower was complete. Talal Al Maiman, chief executive officer and managing director of Kingdom Real Estate Development Co. said in an interview "We have all the investors, all the finance, all the money we need," Al Maiman said. "It took us beyond 20 months to convince investors, working every detail and aspect of financing." On 10 October 2012, Kingdom Holding awarded contracts totalling $ 98 million. Kingdom Holding Co. has signed
14910-420: The latter is taught in formal education settings. However, there have been studies reporting some degree of comprehension of stories told in the standard variety among preschool-aged children. The relation between Modern Standard Arabic and these dialects is sometimes compared to that of Classical Latin and Vulgar Latin vernaculars (which became Romance languages ) in medieval and early modern Europe. MSA
15052-883: The many national or regional varieties which constitute the everyday spoken language. Colloquial Arabic has many regional variants; geographically distant varieties usually differ enough to be mutually unintelligible , and some linguists consider them distinct languages. However, research indicates a high degree of mutual intelligibility between closely related Arabic variants for native speakers listening to words, sentences, and texts; and between more distantly related dialects in interactional situations. The varieties are typically unwritten. They are often used in informal spoken media, such as soap operas and talk shows , as well as occasionally in certain forms of written media such as poetry and printed advertising. Hassaniya Arabic , Maltese , and Cypriot Arabic are only varieties of modern Arabic to have acquired official recognition. Hassaniya
15194-795: The need for a lexical injection in Arabic, to suit concepts of the industrial and post-industrial age (such as sayyārah سَيَّارَة 'automobile' or bākhirah باخِرة 'steamship'). In response, a number of Arabic academies modeled after the Académie française were established with the aim of developing standardized additions to the Arabic lexicon to suit these transformations, first in Damascus (1919), then in Cairo (1932), Baghdad (1948), Rabat (1960), Amman (1977), Khartum [ ar ] {{main other| (1993), and Tunis (1993). They review language development, monitor new words and approve
15336-424: The one whose sound is heard but whose person remains unseen. Now the term al-hatif is used for a telephone. Therefore, the process of tawleed can express the needs of modern civilization in a manner that would appear to be originally Arabic. In the case of Arabic, educated Arabs of any nationality can be assumed to speak both their school-taught Standard Arabic as well as their native dialects, which depending on
15478-549: The overhaul of Arabic grammar first proposed by Al-Jahiz 200 years prior. The Maghrebi lexicographer Ibn Manzur compiled Lisān al-ʿArab ( لسان العرب , "Tongue of Arabs"), a major reference dictionary of Arabic, in 1290. Charles Ferguson 's koine theory claims that the modern Arabic dialects collectively descend from a single military koine that sprang up during the Islamic conquests; this view has been challenged in recent times. Ahmad al-Jallad proposes that there were at least two considerably distinct types of Arabic on
15620-411: The pad over 90 m (300 ft) across, yet the building, which will weigh over 900,000 tonnes (890,000 long tons; 990,000 short tons), is expected to settle. The idea is that it settles evenly enough so that the building does not tip or put undue stress on the superstructure . Computer modelling programmes performed tests at the site to confirm that the foundation design would work. A later design for
15762-400: The physical challenges, Adrian Smith states that practicality is still the greater challenge over structural durability, even in such super-tall designs, and that as with all buildings, Jeddah Tower's form was primarily derived respective of what the building's uses would be, then in accordance with the structural factors that would have to be considered to deliver it. Orange S.A. are designing
15904-692: The previous world's tallest building title holders, the Petronas Towers in Kuala Lumpur and the Taipei 101 in Taiwan, as well as the under construction Ping An Finance Centre in Shenzhen , which will be the second tallest building in China after completion. Saudi Binladin Group is the largest construction firm in the Middle East, with over 35,000 workers and hundreds of projects. In 2012, they constructed
16046-409: The project had been put on hold due to the global financial crisis of 2008–2009 and that Bechtel (the initial engineering firm for this project) was "in the process of ending its involvement with the project." Kingdom Holding Company quickly criticized the news reports, insisting that the project had not been shelved. In March 2010, Adrian Smith of Adrian Smith + Gordon Gill Architecture (AS + GG)
16188-466: The recovery effort. 2004—Taipei 101 (Taipei, Taiwan) Completed: The first 21st-century building to become the world’s tallest upon completion, Taipei 101 is, as its name implies, a 101-story tower. Working with engineer of record Evergreen Consulting, Thornton Tomasetti established an efficient steel-based dual structural system and solved wind behavior problems with distinctive double stair-step corners. By 2020, Thornton Tomasetti had designed five of
16330-410: The region may be mutually unintelligible. Some of these dialects can be considered to constitute separate languages which may have "sub-dialects" of their own. When educated Arabs of different dialects engage in conversation (for example, a Moroccan speaking with a Lebanese), many speakers code-switch back and forth between the dialectal and standard varieties of the language, sometimes even within
16472-513: The roads and over 27,000 buildings in Jeddah. According to a representative of Standard Chartered , which invested US$ 75 million in Saudi Binladin Group, Saudi Arabia is going to spend over US$ 400 billion (SR1.5 trillion) on infrastructure over the next few years. According to reports by Citi Investment Research & Analysis , $ 220 billion worth of development, accounting for 36% of all construction spending in
16614-458: The same sentence. The issue of whether Arabic is one language or many languages is politically charged, in the same way it is for the varieties of Chinese , Hindi and Urdu , Serbian and Croatian , Scots and English, etc. In contrast to speakers of Hindi and Urdu who claim they cannot understand each other even when they can, speakers of the varieties of Arabic will claim they can all understand each other even when they cannot. While there
16756-458: The sole example of Medieval linguist Abu Hayyan al-Gharnati – who, while a scholar of the Arabic language, was not ethnically Arab – Medieval scholars of the Arabic language made no efforts at studying comparative linguistics, considering all other languages inferior. In modern times, the educated upper classes in the Arab world have taken a nearly opposite view. Yasir Suleiman wrote in 2011 that "studying and knowing English or French in most of
16898-563: The standardization of these new terms throughout the Arabic-speaking world, and toward the development of Arabic as a world language . This gave rise to what Western scholars call Modern Standard Arabic. From the 1950s, Arabization became a postcolonial nationalist policy in countries such as Tunisia, Algeria, Morocco, and Sudan. Arabic usually refers to Standard Arabic, which Western linguists divide into Classical Arabic and Modern Standard Arabic. It could also refer to any of
17040-433: The start of construction was slated as "no later than December." This meant the tower was expected to be completed in 2017, though at that time it was also possible that it could still have been completed by the date the media continued to publish, which was the prior estimate of late 2016. Only if construction had begun promptly and gone smoothly could completion in late 2016 have been achieved. Reports in 2009 suggested that
17182-400: The strength and creative vision of its people. It represents new growth and high-performance technology fused into one powerful iconic form." However, Bob Sinn, principal engineer at Thornton Tomasetti, stated that the practical challenges of building very tall buildings are greater than the structural challenges. "We intend [Jeddah] Tower to become both an economic engine and a proud symbol of
17324-439: The thin desert atmosphere, will cause the outdoor air temperature towards the top of the tower to be lower than the ground level air, which will provide natural cooling. There is also significantly more air flow (wind) at heights, which is very strong at one kilometre and had a large impact on the structural design of the tower. The Burj Khalifa actually takes in the cooler, cleaner air from the top floors and uses it to air condition
17466-523: The time, the tower was about one-third of the way completed. The development halt stemmed from labor problems with a contractor following the 2017–2019 Saudi Arabian purge . No firm timeline for completion has been provided, but in September 2023, a new request for proposals was issued to a multinational group of construction firms to complete the project. The building has been designed to a height of at least 1,008.2 metres (3,308 ft) (the exact height
17608-614: The topped-out 601 m (1,972 ft) Abraj Al-Bait Clock Tower in Mecca , which is the tallest building in Saudi Arabia and fourth tallest in the world, as well as the largest skyscraper in the world by floor area and volume. Aside from buildings, the firm has also constructed many major infrastructure projects, such as the King Abdulaziz (Jeddah) International Airport expansion and the 775 km (482 mi) six lane Al Qassim Expressway through Saudi Arabia. Saudi Binladin Group
17750-463: The tower moved forward after the delay. There was steady progress, but in January 2018, building owner JEC halted structural concrete work with the tower about one-third completed due to labour issues with a contractor following the 2017–19 Saudi Arabian purge . Since then construction work has been stalled, partially due to the COVID-19 pandemic , and as of November 2023, it was uncertain if or when
17892-501: The tower will be finished. In September 2023, the Middle East Economic Digest ( MEED ) reported that Jeddah Economic City had restarted the project and a request for proposals had been issued for a contract to complete the construction of the tower. Fourteen construction contractors from the region, Europe, and China were given three months to prepare their bids. In May 2024, the architect confirmed construction
18034-489: The tower will use its large number of efficient elevators as well as its three sky lobbies , which allows transfers to be made between elevators serving a specific area with no elevator being overburdened. Much was learned from Burj Khalifa that helped with the design of Jeddah Tower not only structurally, but in methods for designing practical mechanical, electrical, and plumbing (MEP) systems, as well as adhering to local regulations and international building codes . Despite all
18176-433: The tower's architect, Adrian Smith, said that the tower "evokes a bundle of leaves shooting up from the ground; a burst of new life that heralds more growth all around it". Smith states that the tower will create a landmark in which it and the surrounding Jeddah Economic City are interdependent. Talal Al Maiman, a board member of Jeddah Economic Company, said, "Jeddah Tower will be a landmark structure that will greatly increase
18318-565: The tower's site alone will take up 500,000 m (5,381,955 sq ft). As with many other very tall skyscrapers, including the Kingdom Centre in Riyadh , which is generally considered to have sparked the recent significant commercial developments around it in the district of Olaya , much of the intention of Jeddah Tower is to be symbolic as well as to raise the surrounding land value rather than its own profitability. To that effect,
18460-501: The towns where the inscriptions were discovered (Dadanitic, Taymanitic, Hismaic, Safaitic). However, most arguments for a single ANA language or language family were based on the shape of the definite article, a prefixed h-. It has been argued that the h- is an archaism and not a shared innovation, and thus unsuitable for language classification, rendering the hypothesis of an ANA language family untenable. Safaitic and Hismaic, previously considered ANA, should be considered Old Arabic due to
18602-499: The usable airspace. While skyscraper experts have stated that towers well over one kilometre, even two kilometres (6,600 feet) high, are technically feasible, physical sustainability and practicality issues come into play in towers of this height. As for physical restraints, Bart Leclercq, head of structures for WSP Middle East recently said, "I truly believe that 1 mile, 1.6 kilometres, is within range. Over that, it may be possible if there are improvements in concrete quality. But 2 km
18744-450: The value of the hundreds of other properties around it in Jeddah Economic City and indeed throughout North Jeddah." The concept of profitability derived from building high density developments and malls around such a landmark was taken from the Burj Khalifa, where it has proven successful, as its surrounding malls, hotels, and condominiums in the area known as Downtown Dubai have generated the most considerable revenue out of that project as
18886-424: The victims of 9/11 as there is no evidence of the construction firm financially supporting bin Laden after he was removed as a shareholder following the 1993 World Trade Center bombing . The building uses a Buttressed core . In addition to its primary functions, the building is slated to include a significant amount of retail as well as a wide variety of other unique amenities with the intention that it functions as
19028-451: The world have classes that teach Arabic as part of their foreign languages , Middle Eastern studies , and religious studies courses. Arabic language schools exist to assist students to learn Arabic outside the academic world. There are many Arabic language schools in the Arab world and other Muslim countries. Because the Quran is written in Arabic and all Islamic terms are in Arabic, millions of Muslims (both Arab and non-Arab) study
19170-486: The world. Furthermore, the Pearl River Tower is a unique tower that was originally designed to use zero net energy by drawing all its needed power from wind , sunlight , and geothermal mass , though this design goal was not fully achieved. In October 2010, the owners (Kingdom Holding Company) signed a development agreement with Emaar Properties PJSC. The final height of the building was questionable, but it
19312-653: Was completed in December 2013. Above ground construction commenced in September 2014. In late 2017, the owner of Kingdom Holding Co, which owns 33% of the tower, and the chairman of the Saudi Binladen Group, which owns 17% and is the primary contractor, were both arrested as part of the 2017 Saudi Arabian purge . Construction of the tower continued, although some senior managers at Kingdom Holding were redirected to other projects. In February 2018, Mounib Hammoud, CEO of Jeddah Economic City, said that construction
19454-411: Was proposed for a large area of undeveloped waterfront land with an area of 5.2 km (2.0 sq mi). The area is located roughly 20 km (12 mi) north of the port city of Jeddah. Jeddah Economic City was designed by HOK Architects , and is estimated to cost at least SR75 billion (US$ 20 billion) and take around ten years to build. The development is envisioned to grow into
19596-602: Was reported that the Saudi Water Company had signed a 2.2 billion-riyal ($ 587 million) supply deal with Jeddah Economic Co. for the Jeddah tower project. The 25-year agreement to supply 156,000 cubic metres of treated and drinking water a day, enough for 62 Olympic-size pools, was signed by the chief executive of the Jeddah-based developer, Waleed Batraji, and Loay al-Musallam, head of National Water Company. Construction started on 1 April 2013. Piling
19738-448: Was resumed with completion estimated in four to five years, which would create an estimated completion date to occur in 2028 or 2029. Sustainability of such a tall building would include problems such as vertical transportation limitations, with elevators only being able to go so far; building swaying, caused by wind; and super column settling, which occurs because concrete tends to shrink as it hydrates and settles under load, whereas steel
19880-401: Was selected as the preliminary architect (though they deny involvement in the earlier, mile-high designs). Later, when the proposal was more serious, they won a design competition between eight leading architectural firms, including Kohn Pedersen Fox , Pickard Chilton, Pelli Clarke Pelli, and Foster + Partners , as well as the firm Smith formerly worked for, Skidmore, Owings and Merrill , which
