1. Earthquake Resistant Models

And following various guidelines which we showed by the GSDMA and all others IS codes, Kutch Nava Nirman Abhiyan of that time has developed many of the models earthquake resistant, one is G+1 model, one is the imitation of the Bonga, what you can see is the plinth band, sill band on the roof band.

The Kutch Nava Nirman Abhiyan was an initiative in response to earthquake damage that focused on developing models resistant to seismic activity. This initiative relied on guidelines provided by the GSDMA (Gujarat State Disaster Management Authority) and various Indian Standards (IS codes). Among the models produced, the G+1 model (which means ground plus one additional floor) and a model designed to imitate traditional structures known as 'Bonga' were notable. Key architectural features of these models included plinth bands (horizontal bands at the foundation) and sill bands (horizontal bands at window or door levels), both of which help to stabilize the structure during earthquakes.

Think of how a bridge is built to withstand heavy traffic and strong winds. Just like engineers use specific designs and materials for bridges, in earthquake-prone areas, architects apply special techniques to ensure buildings can endure shaking. This is comparable to how safety harnesses are designed to keep workers secure at heights.

So, following these codes as well as the guidelines which has been issued by the authorities, so they also demonstrated that how the transfer of this technology can be implemented like the upgradation of the Bonga roof. So that is where they are talking about the octagonal conical roof with the help of truss, fabricated truss.

Building authorities not only established modern earthquake-resistant structures but also sought to enhance traditional designs. For instance, they improved the Bonga roof by incorporating advanced designs like octagonal conical roofs supported by fabricated trusses. These roofs are both aesthetically pleasing and practical, as they distribute seismic forces more evenly, helping to keep buildings stable during earthquakes.

Imagine upgrading a classic car with modern technology; while the car retains its vintage look, enhancements like better suspension and more robust materials ensure it runs smoother and is safer. Similar upgrades were made to traditional roof designs to enhance their resilience.

Also, some of the circular models which is a hemispherical dome. This is completely done with the bricks, you know with the mud blocks. And the Ferro-Cement Channels which I have showed you just now how they are fabricated and some of the houses were also constructed on that and as well as some toilets, you can see that these are the precast toilets, toilet units.

The creation of earthquake-resistant structures involved the implementation of circular models, particularly hemispherical domes constructed from bricks and mud blocks, known for their durability. Additionally, materials like Ferro-Cement were used for constructing channels and precast toilet units. These innovations not only improved safety but also facilitated quicker, more efficient building processes in communities affected by earthquakes.

It's similar to how some products, like furniture, are offered as flat-pack items that are easy to assemble at home. Just as these flat-pack products make it more convenient to create a durable piece of furniture, the use of precast materials makes it quicker and safer to build essential facilities after a disaster.

So, even some incorporation of traditional technology like bamboo how we can make use of bamboo and embed that in the shelter forms and thatch. So, there is a combination of both these CSEB blocks, rammed earth as well as thatched roofs, so there is different works.

By integrating traditional technologies, such as bamboo and thatch alongside modern materials like Compressed Stabilised Earth Blocks (CSEB) and rammed earth, innovative and culturally relevant architectural solutions can be developed. This combination emphasizes sustainability and resilience, bridging the gap between modern construction methods and traditional building practices.

Think of a chef who combines old recipes with new cooking techniques to create a unique dish. By respecting traditional ingredients and methods while experimenting with contemporary cooking styles, the chef elevates the dish. Similarly, architects fuse traditional materials with modern techniques for safer, culturally sensitive buildings.

And similarly, in the hospital what you can see is that they are building some units of the geodesic domes which has known for its earthquake-resistant structure and which will have less area and more volume. So, this is the earthquake resistant model built by Nirmithi Kendra...

In hospital designs, geodesic domes have been used as earthquake-resistant structures. These domes offer a strong framework while maximizing internal volume with minimal surface area, which aids in structural integrity. By constructing these models, organizations like Nirmithi Kendra showcase effective and efficient solutions to design disaster-resilient facilities.

Think about how a soccer ball is designed. It has a spherical shape, which distributes force evenly across its surface. This design principle makes it strong and capable of withstanding kicks. Geodesic domes work on similar principles, offering strength and stability in designs.

And the same community hall, the Catholic Relief Services has taken the reconstruction activity of the Paika village...

Community leaders and organizations, such as Catholic Relief Services, actively participate in reconstruction efforts post-earthquake. For instance, in the Paika village, they utilized CSEB blocks and Mangalore tiles to rebuild community structures after they were damaged. These initiatives are vital for restoring a sense of normalcy and community spirit, demonstrating the importance of collaborative recovery efforts.

Imagine a community coming together after a natural disaster to help reconstruct a damaged playground for children; this collective effort symbolizes hope and rebuilding community ties. Similarly, local organizations play crucial roles in restoring communal spaces after disasters.

But now, what you are seeing is a view of the village which has been reconstructed at the same places...

In the reconstruction of a village, existing layouts were preserved intentionally. New houses were constructed adjacent to original ones to maintain the existing community structure and layout. This strategy respects the social dynamics of the community and helps retain familiarity for residents returning to rebuilt environments.

Think about rearranging your bedroom with the same furniture but in slightly different positions; while the space feels fresh, the familiarity remains intact. The reconstruction efforts aimed to keep the village's essence while providing new homes.

There is also some earthquake-resistant models which were developed by Caritas-KVT but these are very not even relevant to this area...

While some earthquake-resistant models were developed by organizations like Caritas-KVT, they faced resistance from locals, who preferred building their houses with stone, despite knowing it may not be the safest option. This highlights the importance of understanding community preferences and beliefs when addressing housing needs and disaster recovery.

Think of someone who chooses to ride a bicycle that feels familiar and comfortable instead of a new model that might be safer but unfamiliar; preference for known options often supersedes concerns about safety. Designers and architects must consider these preferences to ensure their solutions are embraced by communities.

So, this is where we have to learn that what community needs and what community demands and now to give them some guidance...

A key lesson in post-disaster reconstruction is the need to prioritize community input. This means understanding what materials or designs community members prefer, even if they have risks, and providing them with the knowledge to build safely. A support system can help communities make informed choices about construction, thus promoting safety while respecting cultural preferences.

Consider a teacher who offers students options for project topics, enabling them to choose what interests them most. By valuing student input, the teacher creates empowerment. Similarly, architects should empower communities by engaging them in the design and building process to foster ownership and better results.

So, these are some of the examples from the Gujarat earthquake whereas in following the Gujarat we have Tsunami...

The experiences gained from responding to the Gujarat earthquake laid the groundwork for future disaster responses, including the Tsunami that affected Tamil Nadu. Quick lessons learned from how communities rebuilt after one disaster informed strategies for managing subsequent disasters, improving resilience in affected areas.

Imagine a sports team learning from their previous games; by analyzing what worked and what didn’t, they can improve their performance in future matches. Similarly, communities adapt and evolve their disaster response strategies based on experiences from earlier challenges.
