1.1. G+1 Model and Imitation of Bonga

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.

This chunk introduces the concept of earthquake-resistant models developed after a significant earthquake. The Kutch Nava Nirman Abhiyan initiative aimed to improve construction standards using guidelines from the Gujarat State Disaster Management Authority (GSDMA) and various Indian Standards (IS) codes. Two particular models highlighted are the 'G+1 model' (a ground floor and one upper floor) and the 'imitation of the Bonga'—a traditional construction style that has been adapted for better performance against earthquakes. Key structural elements mentioned include the plinth band, sill band, and roof band, which are crucial for distributing loads and resisting seismic forces.

Think of a building like a person standing on a soft blob of jelly. If the jelly shakes (like during an earthquake), the person can topple over. To keep the person stable, we can add support, like a strong pair of legs or a belt around the waist. Similarly, the bands in the G+1 model and the Bonga imitation act like supports for the building, helping it stay upright during 'shakes'.

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.

In this segment, it's discussed how the existing building codes and guidelines have facilitated the transfer of technology, particularly towards enhancing traditional building styles like the Bonga roof. The goal is to update and improve these roofs to make them more earthquake-resistant while preserving their cultural significance. Upgrading traditional roofs typically involves incorporating modern materials or engineering practices while still respecting local architectural heritage.

Imagine an old fruit tree in your garden. It has served you well, but every year, strong winds threaten to knock it down. To protect the tree while keeping its old charm, you add some modern supports around it. Similarly, the Bonga roof is being supported with modern techniques to ensure the building remains safe without losing its unique cultural identity.

So that is where they are talking about the octagonal conical roof with the help of truss, fabricated truss. Also, some of the circular models which is a hemispherical dome. This is completely done with the bricks, you know with the mud blocks.

This chunk outlines different innovative architectural designs used in earthquake-resistant construction, such as octagonal conical roofs and hemispherical domes. These designs provide structural integrity and help distribute stress during an earthquake. The use of trusses, which are frameworks used to support roofs, along with materials like bricks and mud blocks, plays a crucial role in achieving durability and strength in these models.

Think of a well-made bridge made of triangular supports. These shapes help hold the bridge up, making it strong against heavy traffic or wind. The octagonal and hemispherical designs similarly create strong buildings, capable of withstanding the forces of nature, effectively acting as 'strong bridges' for roofs against earthquakes.

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.

Geodesic domes are structures made up of a network of triangles that distribute stress evenly. This segment highlights their application in hospital construction, showcasing how they provide efficient use of space while being highly earthquake-resistant. The design allows for more interior volume without requiring extensive ground area, making it ideal for urban settings prone to seismic activity.

Visualize a soccer ball, which is made from hexagons and pentagons. Its design is strong and can withstand kicks without falling apart. Similarly, a geodesic dome provides strength and stability, enabling hospitals to serve as safe havens during emergencies like earthquakes.

What you are seeing is a view of the village which has been reconstructed at the same places like you can see a small Bhongas next to it where they were living temporarily.

This segment describes the reconstruction of a village after an earthquake, emphasizing the importance of community engagement. As the village is rebuilt, temporary structures like Bhongas provide shelter while efforts are underway to create permanent homes. This illustrates the necessity of involving communities in the planning and rebuilding process to meet their needs and retain their cultural identity.

Imagine a community garden. Each person contributes a plant to grow together in a shared space. While they wait for the plants to grow, they set up small tents to keep everyone comfortable. Similarly, during the rebuilding process, communities use temporary homes while actively participating in creating their permanent future.

But now, what you are seeing is a view of the village which has been reconstructed at the same places like you can see a small Bhongas next to it where they were living temporarily. And there is also some earthquake-resistant models which were developed by Caritas-KVT but these are very not even relevant to this area but they are very uniform and standardized forms of the concrete models where people showed their reluctance in not to stay in these houses.

This piece reflects on the challenges faced in the reconstruction process, especially the reluctance of community members to move into standardized concrete buildings. It indicates a gap between what is provided and what the community truly desires, highlighting the importance of designing buildings that resonate with local culture and needs. Acknowledging the community’s perspective is vital for successful rebuilding.

Imagine a pair of shoes that looks great but doesn’t fit well. Even if everyone says they’re the best shoes, if they don’t meet your needs, you won't want to wear them. In reconstruction, it’s essential to listen to what the community wants and needs so they feel at home in their new buildings.
