Published

on

In a groundbreaking achievement, India has unveiled its first 3D-printed post office, located in Bengaluru’s Cambridge Layout. This remarkable feat, completed in just 43 days, represents a significant leap forward in construction technology and efficiency. The inauguration ceremony was held virtually, with Union Minister Ashwini Vaishnaw leading the event. The project was executed by Larsen & Toubro Limited (L&T) in collaboration with the expertise of IIT Madras, revolutionising traditional construction methods.

Efficiency Meets Innovation

The India Post’s 3D-printed post office covers a built-up area of 1,021 square feet, showcasing a striking blend of efficiency and innovation. What makes this project truly exceptional is the use of 3D concrete printing technology, a fully automated building construction method. A robotic printer meticulously deposits concrete layer by layer, following the approved design. Special-grade concrete, which hardens rapidly, ensures the bonding between layers, allowing for the swift creation of the structure.

George Abraham, Head of Operations (South and East) at L&T, emphasised the impact of robotic intervention in achieving this remarkable feat. Compared to the conventional construction method, which typically takes 6-8 months, the 3D-printed post office was completed in a mere 43 days. This not only accelerates the construction process but also reduces costs significantly.

Cost-Effective and Sustainable

The 3D-printed post office project was executed at a cost of Rs 23 lakh, making it approximately 30-40 percent more cost-effective than traditional construction methods. Professor Manu Santhanam, from the Building Technology and Construction Management Division at IIT Madras, highlighted the critical factors that contributed to the success of concrete 3D printing. He explained that the project incorporated indigenous machines and robots while utilizing a special concrete material with exceptional properties.

IIT Madras and L&T conducted extensive meetings to ensure the project’s success. Professor Ravindra Gettu from IIT-M played a pivotal role as the primary advisor, ensuring the compatibility of the 3D-printed technology with conventional construction. The project involved detailed assessments of materials, structural design, construction methodology, and concept approval. Additionally, Professor Gettu conducted site visits to ensure on-site quality and provided guidance on curing and technical matters.

Innovative Technology for the Future

The 3D printing technology employed in the post office project was flexible and adaptable. It allowed for curved surfaces and adapted to site dimensions, eliminating the constraints of flat walls. This technology enabled continuous reinforced concrete footing and three-layer walls, combining concrete and reinforced concrete for added strength and durability. Moreover, it facilitated the incorporation of weather-proofing and utilities within the walls, enhancing construction efficiency.

The Future of 3D Printing

Developers believe that 3D printing’s unique ability to enable individual customization and weather-proofing will play a vital role in housing-related construction. Chief Postmaster General of Karnataka Circle, Rajendra Kumar, noted that the larger goal is to harness 3D printing technology for low-cost housing projects. Plans are underway to construct post offices across 400 vacant sites in the state, where postal services are currently inaccessible. This pioneering project is expected to serve as a blueprint for the future development of affordable, efficient, and sustainable construction methods using 3D printing technology.

Conclusion

India’s first 3D-printed post office in Bengaluru stands as a testament to the country’s progress in construction technology. With its speed, cost-effectiveness, and sustainability, 3D printing has the potential to revolutionise the construction industry and address pressing challenges, including low-cost housing. As the nation looks to expand this innovative approach to post offices and beyond, it opens doors to a brighter and more efficient future in the realm of construction and infrastructure development.

A Tale of Two Rivers: Yamuna and Sabarmati

India considers its rivers sacred. In Hinduism some are even personified as goddesses. Yet, paradoxically, these revered rivers often bear the brunt of abuse and pollution. Vital to the rise of civilizations, rivers are lifelines without which cities cannot thrive.

In this documentary we explore the tale of two rivers, Sabarmati and Yamuna both are lifelines of their respective cities, yet they stand as stark opposites. Life resides on the banks of both the rivers but people of Yamuna breathe poison while Sabarmati riverfront Ahmedabad provides a haven for leisure, economic activities, and community life.

The Sabarmati Riverfront showcases a governance model that marries urbanization with environmental preservation. Often mistaken as the capital of Gujarat, Ahmedabad stands as a stellar example of city planning and sustainable development. For decades, the Sabarmati was a neglected and polluted river. However, the Gujarat government decided to turn the tide.

It decided to use the 100 crore amount from the River conservation program to clean the Sabarmati. It installed pumping stations and sewage treatment plant. This gave the people of Gujarat hope. Soon the Sabarmati riverfront development project was passed and a special purpose vehicle called the Sabarmati Riverfront Development Corporation limited. The river was on its way for a makeover. Soon strategies for flood protection, bank protection, and river training were formulated. On both the banks of the river diaphragm walls were built to sustain floods and the project can sustain levels of 4.75 lac cusecs without spillage into the city.

In stark contrast, the Yamuna, personified as the goddess Yami, remains murky, toxic, and heavily polluted. It supplies 70% of Delhi’s water, yet the 22-kilometer urban stretch between the Wazirabad Barrage and Okhla Barrage—just 2% of its total length—accounts for nearly 80% of the river’s pollution. Every winter, the Yamuna is blanketed in toxic froth, mockingly referred to as the “famous bubble bath” provided by the Delhi government.

Crores of rupees have been invested in cleaning the Yamuna, involving Japan international banks, various plans, and strategies, yet the efforts appear to yield no significant results. The Government of Japan provided loan assistance for implementation of YAP in December-1990. YAP was formally launched in 1993, now called as YAP phase I. The total cost of YAP I along with the additional package was INR 7.32 billion between 1993 and 2003. Subsequently, under YAP II, INR 6.24 billion was allocated between 2004 and 2011, but the project failed to meet its deadlines. In 2019, YAP III was launched as part of the Namami Gange project. Nearly INR 6,856.91 crore was spent over five years, from 2017-21.  In 2023, the Delhi government allocated an additional INR1,028 crore for cleaning the Yamuna, bringing the total to INR 3,139 crore. The Delhi government had received a fund of INR 618.50 crore under the Yamuna Action Plan III from the Central government and had spent around INR 687 crore for cleaning the Yamuna. Ministry of Water Resources, River Development and Ganga Rejuvenation in December 2018 released a sum of INR 2,361.08 crore to the Delhi government for 11 projects for cleaning the Yamuna.

The mathematics of the Sabarmati Riverfront development project is fairly simple and it isn’t merely about the beautification of the river. It is planned to sustain business, economics, people-centric activities, and further development of the city. The project was planned to self-finance. Its success lies behind the transparent approach of the government and SRFDL. Revenue of around INR 450 crore was generated from the sale of reclaimed land. This covered the initial 5 yea₹ of projected construction cost of INR 361 crore. The initial phase, which opened in August 2012, had a cost of INR 1,400 crore (US$160 million) as of November 2019. The second phase, covering 5.5 km on both banks, was approved in 2020 with an initial budget of INR 850 crore. The plan is to extend this to the capital Gandhinagar—26.65 km in multiple phases over the next 15 years.

Gujarat Model made Narendra Modi the 14th Prime minister of India and he has been the prime minister for three consecutive terms. It is a hard to digest pill for many politicians. It truly separates politics from governance and has made Gujarat one of most liveable cities of India. Sabarmati Riverfront development project is an important and beautiful part of the same model. This project is unique because it truly socialized a river, a historic river, which through decades of neglect and decay, had become a pathetic caricature of a river. It is high time that Delhi government learns the difference between politics and governance and utilise money being pumped into the Yamuna river.

In contrast, the Sabarmati Riverfront Project was strategically planned to be self-financing. Revenue of INR 450 crore was generated from the sale of reclaimed land, covering the initial five years of construction costs (INR 361 crore). The first phase, inaugurated in 2012, cost INR 1,400 crore. The second phase, approved in 2020, had an initial budget of INR 850 crore and aimed to extend the riverfront by 5.5 km. Future plans include extending the project to Gandhinagar—26.65 km in multiple phases over 15 years.

The Sabarmati Riverfront epitomizes the Gujarat Model of governance, which separates politics from administration. This model catapulted Narendra Modi to the position of India’s 14th Prime Minister, a role he has held for three consecutive terms. While critics may find this difficult to accept, the Gujarat Model’s focus on transparent governance and sustainable urban development has made Ahmedabad one of India’s most livable cities.

The Sabarmati Riverfront Project exemplifies how a neglected river was revitalized into a thriving social and economic hub. It is high time the Delhi government draws lessons from this approach, moving beyond political rhetoric to effectively utilize the resources allocated for the Yamuna. Clean rivers are not just a matter of infrastructure but a reflection of governance that prioritizes people over politics.

The story of the “Beer Man” killings in Mumbai involves a series of murders that took place between October 2006 and January 2007. The nickname “Beer Man” was given to the unidentified serial killer because beer bottles were found near the bodies of the victims.

Here is a summary of the key points:

  1. Victims: The killer targeted homeless men, often found in secluded areas of South Mumbai. There were seven confirmed victims, and each was killed in a similar manner, often by being bludgeoned to death.
  2. Crime Scenes: The murders took place in various parts of South Mumbai, including the Marine Lines and Churchgate areas. The presence of beer bottles at the crime scenes was a signature element, leading to the moniker “Beer Man.”
  3. Investigation: The Mumbai police launched an extensive investigation, but the case proved challenging due to the lack of witnesses and concrete evidence. The randomness of the attacks and the lack of a clear motive further complicated the investigation.
  4. Arrest: In January 2008, Ravindra Kantrole, a 42-year-old former police informer with a criminal background, was arrested and charged with the murders. Kantrole had been linked to one of the crime scenes through forensic evidence. He was initially convicted of one murder but later acquitted due to insufficient evidence.
  5. Aftermath: Despite the arrest and trial of Kantrole, doubts remained about whether he was indeed the “Beer Man.” The lack of conclusive evidence and the subsequent acquittal left the case unresolved in the eyes of many.

The “Beer Man” killings remain one of Mumbai’s most notorious unsolved murder cases, shrouded in mystery and speculation.
