1. Introduction to Manual Development

First of all, the design of the manual itself is the important thing when you are developing a guidance, for example, this is a zone A, this is how the coding is worked so now, it says UPA 01, UP is Uttar Pradesh, A is what is the zone and within the zone, you might have 2, 3 typologies, so that is where the typology number. So, for example when you say, the state name and then zone; 1, 2, 3, 4, 5, like that.

The design of the manual is crucial in developing guidance for safe housing practices. It begins with how to classify areas into zones based on their geographic identifiers. For example, in the code 'UPA 01,' 'UP' stands for Uttar Pradesh, and 'A' indicates a specific zone within that state. These zones can have further subdivisions called typologies, which categorize the types of structures or habitats in that area.

Think of this manual like a map of a city, where various regions or neighborhoods are labeled. Each neighborhood could have its own unique characteristics and styles of houses, similar to how different zones in the manual carry specific designs and safety considerations.

So, this could be done by ABCDE zone and then within the zone, you have 1, 2, 3, 4 typology, this is how it has been organized and how one can read this document.

Zones can be labeled with letters, such as A, B, C, D, and E, which provide an easy way to reference them. Within each zone, typologies like 1, 2, 3, or 4 categorize building styles or types specific to the vulnerabilities they face in that area. This organization helps builders and architects understand the context and risks pertinent to each region.

Consider how schools group students by grade levels and then by classroom sections. Similarly, the manual sections are organized to direct builders on how to address specific environmental challenges based on location.

For example, you take the Assam state where you have the zone A is here and the zone B okay and the zone C which is towards the Bangladesh and the Manipur side of it and you have the zone D and zone E, so this is how and they are all classified by vulnerability to natural hazards, physiographic and access to building materials and the cultural compatibility.

In Assam, zones are categorized not just simply by their geographic location but also consider factors like vulnerability to natural hazards, access to resources for building, and the local cultural compatibility of the structures. For instance, a zone lying next to a river may need different building strategies compared to a zone located in a hilly area prone to landslides.

Imagine a hospital where different departments deal with specific services like pediatrics or cardiology. Similarly, each zone in Assam caters to its unique needs based on vulnerabilities and local circumstances.

So, here, they have even described what actually this zone A comprises of in the high vulnerability especially to floods and what kind of floods they are talking about, what kind of riverbank erosions, they are talking about and you know, it is also talking about what kind of elevations and the forest cover, so that’s how the descriptions of each zone has been given.

Zone A is described as being particularly vulnerable to floods. The manual outlines the types of floods, including riverbank erosions, and details regarding local geography such as elevations and forest cover. These assessments guide builders in knowing the risks that specific structures need to be fortified against.

Think of how an insurance company assesses risks. If a home risks floods, it follows different guidelines than a house built in a drought-prone area. The manual’s classification allows builders to reinforce homes specifically against predicted local hazards.

Then in the zone A, where we talk about, here, this is the zone A and it is based on the high vulnerability and medium vulnerability cyclonic storms and mostly, low vulnerability riverbank erosion, so here, this particular typology, this is a typology of a house where they try to document it and this response to brick masonry houses with three-inch walls which are most common.

For Zone A, buildings must accommodate various vulnerabilities: primarily high for floods and medium for cyclonic storms. The documentation provides examples, such as a typology for houses made of brick masonry. This typology includes specifications like three-inch wall thickness being common, which influences structural integrity during extreme weather.

Designing a house is akin to preparing a vehicle for a road trip. You consider the terrain (weather) and make adjustments such as ensuring your tires fit the terrain and have enough grip, just as builders consider the environment when designing homes.

Then, comes to the cost estimate, you know the cost estimate for zone A, design one so, when we talk about cost estimate, it covers excavation, brick soiling, PCC, brickwork foundation, brickwork about plinth, concrete, what is the ratio we are talking about 1:1.5:3 always it’s a multiple of the aggregates and the reinforcement steel truss and then GCI sheet and door, window cement and plaster.

The cost estimate for constructing buildings in Zone A includes multiple components such as excavation, foundation work, brickwork, and material specifics. Cost calculations involve ratios relevant to the materials used, such as concrete mixtures. Understanding these costs helps builders budget appropriately and invest wisely in their choice of materials.

Just like planning a family event requires budgeting for food, venue, and decorations, building homes requires detailed budgeting for all the parts and labor, vital for ensuring successful and sustainable construction.
