Rajkumari Ratnavati’s Girl’s “Imagine being School encircled by massive sandstone walls that are curving into a beautiful circular structure in the middle of an extremely hot desert.” In Jaisalmer, a desert town in northen India popularly Clerestory openings in the classrooms create known as \"The Golden City,\" for its array of yellow spotted lighting across the day. Furthermore, it sandstone architecture, temperatures can reach offers natural ventilation to minimise humidity. approximately 120 degrees Fahrenheit (49 degrees The light brown wooden doors, chocolate brown Celsius) at the height of summer. The Rajkumari board and furniture perfectly complement the Ratnawati's school located at a distance away from entire classroom interior. Kellogg, who usually Jaisalmer’s famous sand dunes is an architectural marvel designs high-end residential projects, was that has come up in Kanoi village with an aim to educate motivated by a 2014 trip to Jaisalmer, and wanted girls and empower them. Designed by Diana Kellogg the building to symbolize the hope and resilience of Architects, this epitome symbolizes a gust of knowledge the desert by merging aspects of traditional and education. The design tackled challenges like Jaisalmer architecture with a modern design. temperatures rising to 50°C, sandstorms and heatwaves. \"There are methods to cool spaces that have been For the structure, she opted to use locally sourced used for centuries. What I did is I put them sandstone. Almost 9,000 sq.ft school, comprising a paved together in a combination that worked,\" Kellogg central courtyard, was curvaceously built by local said, adding that indoor temperature, light coming craftsmen. Built in an oval-shaped structure and made of through these stabbed walls creates a cool contrast yellow sandstone, the school blends with the desert with the school interior, also maximizes the landscape with the beautiful Jali wall on the roofs and airflow and keeps the building passively cool. The solar installations ensuring that sustainable principles are school has a blue mosaic floor that spreads over followed. Thus, even amid the scorching temperatures of the elevated walkway on its roof. the desert, the school remains cool without any air- conditioners. The yellowish-brown building blends beautifully with the surrounding golden sands. Nirmaan-3

Additionally, the presence of jalidar walls Classroom Interial view with clerestory openings. provides support and shade for the floor, preventing it from overheating. Solar panels are attached to a metal structure with accuracy. These not only provide power for lights and fans in the school but also double the covered canopy layer on the rooftop. While many of the cooling techniques used at the school could be applied elsewhere in proposition, their effectiveness and sustainability would vary from site to site. Wind directions and different sandstones would regulate temperatures differently to the materials found and used in Jaisalmer. For example, Air conditioning isn't used anywhere in the building, not just because of it's environmental impact but because it isn't common in the area. By adopting traditional and natural cooling mechanisms that the students are familiar with instead, she believes they can get a sense of comfort from their surroundings, leading to greater confidence. The design is efficient enough as it follows the local ancient water harvesting techniques to maximize the rainwater and recycle gray water in the school. Therefore, the courtyard in the complex can harvest 3.5 lakh liters of water and store it in its belly. Moreover, to make the school aesthetically pleasing it took the work of stone cut art by the local workers. In fact, the architect describes the craftsman as magicians for their stonework. It reduces the carbon footprint from transportation and logistics. Internal view of COURT YARD The project, which is meant to empower women and girls through education in a region where the female literacy rate is the lowest in India, was commissioned by CITTA, a US non-profit organization that provides economic and education support to women in remote and marginalized communities. It is the first step in a three-part architectural project that will also include a women's cooperative center and an exhibition space. It is an AD100 award-winning, sustainable school in Jaisalmer.

The Anji Khad bridge, India’s first cable-stayed bridge and the first-of-its-kind in the country, is currently under construction. The Anji Khad bridge is being constructed in the Reasi district of the Union territory of Jammu and Kashmir. This cable- stayed rail bridge is proposed for connecting Katra and Reasi section of Jammu-Baramulla line in Jammu & Kashmir. With an estimated cost of INR 458 crore, Indian Railways in collaboration with Hindustan Construction company decided to build this cable-stayed rail bridge at Anji Khad. The bridge is situated over the Anji river and is ranked as the second most important bridge on the Udhampur-Srinagar-Baramulla rail project after Chenab Bridge. In October 2016, it was decided to build a cable-stayed bridge at Anji Khad. Actually the plan is to build an arch bridge similar to the Chenab bridge which was abandoned due to the vulnerability of the structure primarily due to concerns over the geological instability of the region. Later in 2016, Indian Railways decided to build a FIG:OPEN SPANDREL VIEW OF BRIDGE cable-stayed bridge considering the geographical aspects. The proposed bridge will connect tunnel T2 on Katra side to tunnel Anji Khad Bridge is one of the most daunting T3 on the Reasi side. The bridge is about 80km by road from projects taken up by the Indian Railways. The Jammu city. It is located in the picturesque mountains of the asymmetrical cable-stayed bridge is balanced on the Himalayas. Due to the complex, fragile and daunting axis of a central pylon. This bridge is part of the geological features, detailed site-specific investigations were national project of the Udhampur-Srinagar- Baramulla Rail Link (USBRL) Project. Being the carried out by IIT Roorkee and IIT Delhi respectively. most focused ongoing projects in India, USBRL is being strictly monitored by the central government of India. The central government had started its construction in order to connect the mountainous areas with the mainland of the country. And the prime element of this project is the Anji Khad Bridge — India’s first cable-stayed bridge. The length of bridge’s main section is 473.25m long out of the total length of over 1300m with 120m long viaduct and this bridge is supported by 96 cables which are made up of steel. Even due to the sheer complex nature of the geographic location of the bridge, it is built quite robustly as it can withstand 213kmph of winds and has the capacity to bear earthquakes of the highest intensity. FIG:SIDE VIEW OF CABLE BRIDGE Nirmaan-5

The Reasi yard station, which is a part of the project, has been built on high, rectangular, tapered hollow piers, that are 105m in height, with the bridge spanning about 490m. The bridge is made using 7,000 reinforcement steel and 6,700 million tonnes of structural steel. Unique and advanced techniques and equipment, including pump concreting system arrangement, have been used in the construction of the bridge. The pump Concreting System arrangement was used to increase efficiency, giving a higher safety for workers and saving construction time by about 30 percent. The Anji Khad bridge will have access to an integrated monitoring system using various sensors installed at various locations on the bridge which will continuously monitor the load acting on the bridge. The project requires extremely diverse loads to be hoisted, for which reason HCC needed a tower crane equipped with an automatic trolley change. This system, along with the Power Lift system, allows variable loads to be dealt with efficiently while ensuring the crane achieves maximum efficiency. A 25-ton 21CM550 tower crane is working on the construction site of Anji Khad bridge which was specially imported from Spain for this particular project. These cranes are equipped with a lightning protection system designed to prevent damage to electronic devices. FIG:VIEW ON MAIN BRIDGE This project will be making an enormous impact in merging the Kashmir valley with the rest of Indian Railway network and giving rise to huge economic growth and development for Jammu & Kashmir.
