Battersea Power Station Development:

The Revitalization of a UK Landmark

Battersea Power Station was a decommissioned coal-fired power station, located on the south bank of the River Thames, in Nine Elms, Battersea, in the London Borough of Wandsworth.

The power station was one of the world’s largest brick buildings and one of the last major symbols of London’s industrial past.

After the building remained empty for almost 40 years, a redevelopment plan kicked off with the mission to build a new iconic London landmark.

The 3rd phase consists in the creation of the so-called ‘Electric Boulevard’, which will include a connection to the Northern Line Extension station, more than 1,300 residential units, a 160-room hotel, retail spaces, restaurants and leisure facilities.

Dextra has been supplying several rebar coupler solutions to the site.

More than 100,000 Griptec and Rolltec cast-in-situ couplers were applied in masonry cells to alleviate the problem of rebar congestion due to long lap length.

Moreover, precast concrete panels reinforced by rebars were used in the building, equipped with 30,000 Groutec couplers for onsite connection of continuation bars.

The panels were easily lifted into place at the construction site: coupler cavities were then filled with non-shrink grouting mortar through the injection holes.

Finally, 3,000 Unitec bolted couplers were installed on rebars for repair works. These couplers were used to replace the damaged reinforcements with new ones and to connect to the finished structure.

The mixed-use community is anticipated to be completed in 2020 and to become a new landmark for locals, tourists and residents.

The Link is a 242-meter-high skyscraper in France, and one of the most recognizable structures in the heart of Europe’s largest business district. The building, located in Paris La Défense, will be the tallest high-rise in the country and a prime example of innovative engineering and cutting-edge technology in the world of architecture.

One of the key factors that sets this building apart from others is the use of Dextra’s Fortec coupler for the reinforcement of its structure. Fortec coupler is a highly advanced and innovative solution for reinforcing concrete structures, and it was used throughout the building to ensure maximum strength and stability.

The building is being constructed with a focus on sustainability and durability. The use of Fortec coupler was an important part of this effort, as it provides a reliable and long-lasting solution for reinforcing concrete structures. The coupler is made of high-strength steel, which makes it extremely durable and able to withstand the harsh weather conditions in the La Défense area.

Fortec coupler also offers a number of benefits over traditional reinforcement methods. For example, it is faster and easier to install than traditional reinforcement methods, which helps to reduce construction time and costs. It also helps to maintain the structure’s integrity even in the event of an earthquake or other natural disaster.

The Link La Défense building is set to be a marvel of modern engineering, and the use of Fortec coupler is a critical component in its design. The coupler’s durability, reliability, and sustainability will ensure that the building remains a prominent structure in the La Défense area for many years to come.

गुगेनहाइम संग्रहालय

गुगेनहाइम संग्रहालय

गुगेनहेम अबू धाबी आधुनिक और समकालीन कला का एक संग्रहालय है, जो संयुक्त अरब अमीरात के अबू धाबी में सादियात द्वीप सांस्कृतिक जिले में स्थित है। जैसे ही इस विस्मयकारी संग्रहालय ने आकार लिया, कई चुनौतियों को दूर करने की आवश्यकता थी, और डेक्सट्रा ने संरचना को महत्वपूर्ण सुदृढीकरण प्रदान किया, जिससे इसकी स्थिरता, स्थायित्व और समग्र सफलता सुनिश्चित हुई। हमने आश्चर्यजनक 140,000 बार्टेक कप्लर्स, 30,000 रिपेयरग्रिप कप्लर्स, 50 टन जियोटेक रॉक बोल्ट और डीसीपी एंकर के 199 सेट की आपूर्ति की, जिससे इस प्रतिष्ठित कृति के निर्माण में महत्वपूर्ण योगदान मिला।

बार्टेक कप्लर्स के साथ संरचना को मजबूत बनाना:

डेक्सट्रा के बार्टेक कप्लर्स द्वारा प्रदान किए गए सुदृढीकरण की बदौलत गुगेनहेम अबू धाबी लंबा और गौरवान्वित है। 140,000 बार्टेक कप्लर्स की आपूर्ति के साथ, डेक्सट्रा ने सुनिश्चित किया कि संरचना में कंक्रीट सुदृढीकरण मजबूत और लचीला बना रहे। ये कप्लर्स मजबूत सलाखों के बीच एक विश्वसनीय यांत्रिक कनेक्शन प्रदान करते हैं, जिससे संरचना की समग्र ताकत बढ़ती है।

रिपेयरग्रिप कप्लर्स के साथ निर्बाध रीबार कनेक्शन:

30,000 रिपेयरग्रिप कप्लर्स का उपयोग बिना किसी तैयार धागे के सरिया को जोड़ने में मदद करता है, जिससे सरिया का निर्बाध कनेक्शन सुनिश्चित होता है और संरचनात्मक विफलता का जोखिम कम हो जाता है।

जियोटेक रॉक बोल्ट के साथ चट्टानों को स्थिर करना:

कप्लर्स के अलावा, डेक्सट्रा ने संग्रहालय के आसपास की चट्टानों को स्थिर करने के लिए 50 टन जियोटेक रॉक बोल्ट प्रदान किए। ये रॉक बोल्ट महत्वपूर्ण एंकर के रूप में काम करते हैं, प्राकृतिक संरचनाओं को मजबूत करते हैं और उनकी स्थिरता को बढ़ाते हैं। उनका उपयोग करके, निर्माण टीम ने साइट से जुड़े भूवैज्ञानिक जोखिमों को प्रभावी ढंग से कम किया, जिससे संग्रहालय के लिए एक सुरक्षित नींव सुनिश्चित हुई।

डीसीपी एंकरों के साथ समुद्री दीवार को बनाए रखना:

संग्रहालय, जो तटों पर शान से खड़ा है, को मजबूत समुद्री दीवार प्रतिधारण की आवश्यकता थी, और डेक्सट्रा के डीसीपी एंकर ने आदर्श समाधान प्रदान किया। डीसीपी एंकर के 199 सेटों की आपूर्ति के साथ, समुद्री दीवार को प्रभावी ढंग से मजबूत और सुरक्षित किया गया। एंकर तटीय संरचनाओं के लिए विश्वसनीय और कुशल रिटेनिंग समाधान प्रदान करते हैं, जो लहरों और ज्वार जैसी गतिशील ताकतों के सामने स्थिरता प्रदान करते हैं।

पूरा होने पर, इसे गुगेनहाइम संग्रहालयों में सबसे बड़ा बनाने की योजना है।

Qatar’s General Electricity & Water Corporation (KAHRAMAA) is currently building fresh water reservoirs to store the equivalent of 7 days of Qatar’s national consumption of fresh water at WHO (World Health Organization) standards. The primary reservoirs are located in five different sites in Doha area: Um Baraka, Um Salal, Rawdat Rashid, Abu Nakhla, and Al Thumama.

The first phase of the project involves the construction of 5 mega reservoir sites, and will support the expected water demand at horizon 2026. The second phase includes the construction of 16 additional reservoirs within the five existing mega sites. With a capacity of 3.5 million m3 each, the Reservoirs are among the largest of their kind in the world.

For this project, Dextra Middle East delivered more than 3 million बार्टेक couplers to the rebar fabricators and contractors involved on the different packages.

Project requirements regarding corrosion protection specify that the complete reinforcement, including couplers, should be epoxy coated. Dextra is therefore delivering all Bartec couplers with epoxy coating, giving them a distinctive green look.

Emirates’ Bustanica Vertical Farm

The World’s Largest Vertical Farm

Emirates’ Bustanica Vertical Farm is the world’s largest vertical farm, a sprawling indoor farming facility spanning an impressive 330,000 square feet. This state-of-the-art facility plays a crucial role in providing fresh, locally sourced in-flight food for Emirates and several other airlines operating at Dubai International Airport. At the core of this groundbreaking project lies meticulous engineering, and one crucial component that contributes to its success is the use of Dextra Groutec couplers for the precast shear wall module connections.

This vertical farm employs cutting-edge technology to cultivate a diverse range of crops in a controlled environment. By stacking layers of crops vertically, the facility maximizes space utilization while minimizing resource consumption. The result is a sustainable and efficient system that produces fresh, high-quality produce year-round, regardless of external climatic conditions.

The Role of Dextra Groutec Couplers

In any construction project, the choice of materials and components is critical to ensuring structural integrity and long-term durability. In the case of the world’s largest vertical farm, the engineers faced the challenge of connecting precast shear wall modules securely. The solution came in the form of Groutec L couplers with a diameter of 25mm.

Groutec couplers are renowned for their reliability and strength in connecting precast concrete elements. These couplers provide a robust and efficient means of joining precast concrete components, ensuring the structural stability of the entire facility. The 25mm diameter was carefully selected to meet the specific requirements of the shear wall modules, offering a seamless connection that enhances the overall resilience of the vertical farm.

The Groutec couplers not only facilitate the structural integrity of the vertical farm but also align with the project’s commitment to sustainability. The durability and reliability of these couplers ensure that the connections withstand the test of time, supporting the longevity of the facility and its contribution to sustainable agriculture.
