KSA : Kingdom Tower (Mile-High Tower)

Why are you burning with anger, i asked question than you start war, I have yet to see a product living North America built by Saudia, but i see every thing from a fantastic Tvs, to fridges to washers and dryers to computer like Samsung, tablets, cell phones, and not to mention cars, cars, and more beautiful cars, i have yet to see any such thing built in S.A.


Don't worry genius ! One thing at a time.

challenge of tall towers need something to grip it firmly below. or spread its bottom plate to hold the tower. how much does dubai cost and this one seems cheaper?

Yes, not only is that guy obviously a "genius" the other guy is confusing a coastal city along the beautiful and tropical Red Sea and Hijaz in general with the beautiful natural areas of the Rub' al-Khali. Ignorants being ignorants.

Nor do they have any clue about the enormous infrastructural projects in the KSA, some of the biggest in the world, who is paying for the Kingdom Tower and what it means for the country, Thuwal, the Jeddah/Makkah region, the country's economy, the big progress on all fronts etc.
Obviously the reasons for the butthurt are well-known though.:enjoy:

Because when it is ‘your own companies’ are doing the work - because they have reached all technological levels necessary - , it always costs less expensive.

Figure 2. Kingdom Tower Y-shaped plan​
Supertall Buildings and Wind

The Y-shaped plan forming the base of the design offered several advantages. A 120-degree separation between wings allows for views to be expansive but not directed toward adjacent units, which would have created privacy issues. A Y-shaped plan would provide a higher ratio of exterior wall to internal area, which would maximize the residential units’ views and exposure to light (see Figure 2).

The “Y” shape also allowed the spreading of the base of the tower without increasing the depth of the lease-span. This means that the building can still maintain a reasonable 10:1 height to width ratio without having a large amount of unusable deep internal space. The “Y” shape also helps develop a clean and simple structural diagram in which every element participates in both gravity and lateral support. If one considers the shape as being similar to a wide flange beam with its mass of structural material at the end of each wing (the “flanges”) where it is most optimally placed, connected by shear walls (the “webs”) forming the corridor walls and core, the structural efficiency is maximized by placing the material where it will do the most good in resisting wind-induced bending loads. The triangular core thus formed by the shear walls is also an optimized shape, very good at resisting wind induced torsion. Lastly, the unique nature of the Y-shaped plan and structure allows for certain serendipitous results. Having three legs, the plan naturally has at least three stairs, creating an immediate redundancy. With its continuous, reinforced concrete shear walls, those stairs are completely enclosed within a very robust and secure environment, again enhancing that aspect of the life safety system of the tower. Furthermore, these very thick shear walls provide more than the minimum required fire separation and are a very effective sound-control mechanism between public corridors and private residential spaces (see Figure 2).

Figure 3. Kingdom Tower tapering shape​

Early on, it was also decided that the tower could not just be vertically extruded. Had that approach been pursued, wind vortices would have become organized on the sides of the tower and amplified the effect, inducing accelerations of lateral movement well above advisable levels as these amplified vortices approach the resonant frequency of the tower. To counter this natural magnification, one very typical approach is to reduce the plan size of the tower as it rises in height. On Burj Khalifa, the tower has 27 tiers with setbacks/plan shape reductions at each. Similar to Burj Khalifa, Kingdom Tower “confuses the wind” by reducing the cross-sectional size of the tower as it rises. However unlike Burj Khalifa, Kingdom Tower does it by means of a continuous taper to each wing (see Figure 3). A continuous taper was a result of one of the primary lessons learned in the construction of Burj Khalifa. Eliminating the stepped setbacks as on the Burj obviated the need for outrigger transfers and belt trusses at certain locations, which in turn will reduce the concentration of structural loads as well as permit a more efficient, continuous, and uninterrupted construction process. Furthermore, having different rates of taper to each wing results in different termination heights for each, thereby creating the dramatically distinct three part spire of Kingdom Tower. This intuitive concept was confirmed by wind studies performed by RWDI at its facility in Toronto.

The structure for the Kingdom Tower is comprised entirely of cast-in-place reinforced concrete walls, coupling beams, and conventionally reinforced flat plate concrete floor framing (see Figure 4). The structure contains no outriggers or wall/column transfers. Due to the continuous and uninterrupted vertical nature of the walls for the tower, a highly efficient jump form system can be utilized. Formwork for the floor slabs also can be reused due to the highly repetitive geometry of the tower. The faces of the shear walls are all vertical, with the exception of the ends of each wing, which taper to follow the form of the Tower. This can be accomplished by a simple shift of between 200 and 300 millimeters for each 4 meters vertical lift or internal blockouts in formwork that is lifted vertically. Because the ends of the shear walls slope, the taper at the end of each wing is created by a consistent 3.5 meter cantilever extension of the slab edge. All building envelope notching is achieved by simply dropping off slab edge cantilevers.

Figure 4. Structural components​

Through this concept of dropping off structural components to create the architectural expression, and allowing formwork to easily jump up on each level of the tower, a highly efficient and constructible system is realized while creating a very distinctive form.

Concrete compressive cube strengths required to realize the tower structure are not expected to exceed 115 MPa, and 60 to 80 MPa at significant heights. Advances in concrete mix designs and concrete pumping technology will be brought to bear in order to place high strength concrete in the upper portions of the tower.

The foundations for the tower are a raft supported on bored circular piles located approximately 2.5 meters below existing grade due to site modifications raising the base of the tower (see Figure 5). This modification minimizes the amount of potential dewatering required on the site during construction of the lower levels.

Tower Form, Culture, Site, and Location

As part of a performative design process, any solution should reflect a specific culture, location and time:

In the case of Kingdom Tower, the solution reflects the desire of Jeddah Economic Company (JEC) and the leaders of Saudi Arabia to show the world the potential of their vision of the Kingdom as an increasingly important, vital, and thriving member of the international community. It is also rooted in the desert landscape. The sleek, streamlined form of the tower can be interpreted as a reference to the folded fronds of a growing young desert plant. The way the fronds sprout upward from the ground as a single form, then start separating from each other at the top, is an analogy of new growth fused with technology. As AS+GG partner Gordon Gill explains: “the tower evokes a bundle of leaves shooting up from the ground – a burst of new life that heralds more growth all around it. This symbolizes the tower as a catalyst for increased development around it.”

In terms of the project’s location, studies of sun, wind and views, among many others parameters, informed and guided the design process that shaped the tower. The tower orientation in plan was adjusted to point one wing toward Mecca, while another points almost directly north, by which both the overall solar load was reduced while simultaneously improving the views of the majority of residential units (see Figure 6). As it turned out, that adjustment in orientation also helped mitigate the magnitude of pedestrian level winds in several of the more critical locations, although it slightly increased the overall load due to design wind conditions. Regarding “time,” Kingdom Tower uses current technologies and materials, but also incorporates “future-making” designs. In the field of vertical transportation, for example, the height and program requirements will be a challenge that elevator manufacturers have accepted in agreeing to develop what will be the world’s tallest multi-deck elevator. In a similar vein, the location and height of the towers’ mechanical floors will push the technology of the buildings’ chilled water, sprinkler, and domestic systems and equipment with their limits to working pressure and capacity.

November 4, 2014

HRH Prince Alwaleed Bin Talal Bin Abdulaziz Alsaud, Chairman of Kingdom Holding Company (KHC) and board members of the Jeddah Economic Company (JEC), paid a visit to the location of the Kingdom Tower and The Kingdom City in Obhor north of Jeddah, to view work in progress on the project and observe at first hand the achievements made so far.

Prince Alwaleed commented: “World’s tallest tower construction work picking up pace and plans to reach 6th floor by end of 2014.”

Prince Alwaleed expressed his satisfaction with the progress made in accordance with the project schedule and praised the efforts made by the project team to finalize works within the specified deadline while maintaining the highest standards of quality.

At a press conference held on the occasion of the visit, guests were given an overview of the project and shown the progress that has been made in the implementation stages. Commenting, Eng. Talal Ibrahim Al Maiman, Executive Director Development and Domestic Investments, Chairman and CEO of Kingdom Real Estate Development Company (KRED), a board member of Kingdom Holding Company stated that work on the Kingdom Tower project, which will be the highest in the world at more than 1,000 meters and is being built on an area of 85,000 sqm at a total cost of SR 4.6 billion, is moving at an accelerated pace using the best and most advanced techniques.

Earlier, Prince Alwaleed headed the board of directors meeting of Jeddah Economic Company in Jeddah with the board members; Mr. Abdulrahman Hassan Sharbatly, Mr. Saleh Bin Laden, Mr. Samaual Bakhsh and Eng. Talal Almaiman.

The Kingdom City and Kingdom Tower project will be a source of pride for the Saudi people and for the citizens of Jeddah in particular. The master plan of the project is designed to build a city on an area of 5.3 million sqm supported by an advanced and comprehensive infrastructure. The first phase of the project which is currently under development consists of 1.5 million sqm which comprises of 3.3 million sqm of modern multi-purpose buildings that will reposition the city of Jeddah on the international scene of modern regional cities.

The main purpose of the project is to make available a unique business, residential and entertainment environment that provides top services for the new generation of Saudi citizens, and to be a must-visit business, entertainment, cultural, medical and educational landmark for visitors to Jeddah, as well as playing an important role in creating job opportunities for Saudi youth and contributing to fulfilling the increasing demand for residential units.

Earlier this year, JEC had announced the arrival of the biggest and tallest custom-made cranes supplied by Germany’s Liebherr & WolffKran. The enormous yellow lifting devices, known as “climbing cranes,” are designed to accompany the Kingdom Tower’s growth both externally and internally, in the latter case utilizing any of the building’s 65 interior elevator shafts to make the climb.

Commenting further, Mr. Hammoud said: “The Kingdom Tower will have 85 high-speed elevators and the world’s fastest double-decker elevators that travel at 12m/s. The elevators are designed to produce energy while moving, which contributes to energy conservation and environment protection. In addition, the tower is equipped with other services that will make it an international landmark and a global icon of Saudi Arabia’s progress, success and achievements.”

The Kingdom Tower features 170 stories, seven stories of which will be allocated for the five-star Four Seasons Hotel offering 200 rooms and121 luxury serviced apartments, and seven stories for offices. The Tower will also have 61 stories that include 318 housing units of various types, along with amenities that include gyms, spas, cafes and restaurants, two sky lobbies and world’s highest observation decks, located on the 644 meter-height, enabling visitors to view the city of Jeddah and the Red Sea from high in the sky.

So entire city or several cities being created from scratch ?
Sounds unreal.

Congrats @al-Hasani @Arabian Legend

Well quite a few are while some are extensions of already existing cities or villages. China and dozens of other developing countries have had similar projects and even on a greater scale due to naturally having a much bigger population and a bigger need for urbanization.

Anyway all those new industrial cities in KSA are some of the biggest projects out there currently.:coffee:

It will be amazing though that's for sure.

Check this thread out;

This is just amazing stuff. Congratulations

Thanks.

KINGDOM CITY MASTER PLAN

Location: Jeddah, Saudi Arabia

The Kingdom City project was envisaged as a modern landmark sub‐center in Saudi Arabia. Located on a 530 hectare site north of metropolitan Jeddah along the shores of the Red Sea, the project will have the world’s tallest building as its centerpiece, the Kingdom Tower (currently under construction). The Tower will not only attract foreign investment to the city, but will also be a significant icon both for the city of Jeddah, and for Saudi Arabia.

Calthorpe Associates won an international design competition for the Master Plan of this unique community. The design consists of a master-planned community of distinctive neighborhoods with a commercial core featuring international offices, a first-class retail establishment, unique open spaces and diverse residential communities. The Master Plan is the end result of a series of studies, analyses and the application of urban design principles reflecting the vision and objectives of the client. Through the collaborative efforts between Jeddah Economic Company and Calthorpe Associates, the plan will produce a healthy and vibrant community, an integrated urban environment that will fluidly evolve into the primary economic and social heart of the City of Jeddah.

The project will provide a quality living, working and entertainment environment for the residents of Jeddah, visitors from other parts of Saudi Arabia, and for international visitors. The project is expected to accommodate a population of 210,000 residents and host 197,500 non‐residents who will enjoy its world class facilities.
