And also, you know, don’t have too many offsets you know here, this is like too many, so symmetrical but still it’s too many offsets in it but then either try to make more of a defined shape because that is where you can even have a diagonal bracings, you can have some kind of support system so, it will; it is at least bound to a; this plan should be square or rectangular, if it is rectangular then you need to have a kind of intermediate support systems into it.

Now, asymmetric buildings with empty pockets are more vulnerable to damage because don’t leave these empty pockets, we tried to fill that and that is where these are more stable you know, the symmetric buildings are more stable and also when we say about the row house planning; the row house planning also creates wind tunnel effects because the moment your house is one step to another, next to the shore and then it channels the wind and that is where it can damage the edges of the walls or the corners.

So, that is where you can even you know, now even the zigzag planning avoid wind tunnel effect right, so how actually, you can actually see about, how you can actually, give a little bit of vastness and then reduce it so, the zigzag pattern as well can have some control, it depends on how you are actually orienting it and similarly, the long phase of the building facing the wind direction.

In fact, if you ever visit in the coastal villages of Tamil Nadu and the coastal areas; most of the times your short phase is of the building is facing the wind direction and whereas, in 721 horizontal phase because that is where they have less number of openings and either that, if they are facing that side and they will have less number of openings and otherwise, if they mostly they orient so, the whole building pattern is like you have the seashore and you have these.

In terms of quality control, it is also talks about the material, what are the ratios we have to include. So, when we say about do not use cement and sand to be less than 1.6 okay, 1:6, so for 1 cement and 6 part of the sand. So, you should not make use of the combination of this mortar not less than 1:6, either it is recommended to use 1 sand, 1 cement and 6 sand or 1 lime with 3 sand or 1 cement, 3 lime and 9 sand, so this is a kind of mortar mixes which normally guidelines do recommend and at the end of the day, all these are coming from the proper IS code but these are only a thumb rules.

But still, I could show you some images of what his work and it was very diagrammatic and really illustrative work. He looks into the before coming into the solutions, he actually explains the situation of how the causes you know, this is a very important aspect of developing any guidance, so one has to understand the consequences of these disasters and especially, what are the causes; root causes for it.

And whether it is the form of orientation, whether it is the type of construction, whether it is a citing out you know, so this all for instance, here, you have these normal setup where you have the river level and all of them have built on the top, on the mountains and then the average flood level in case, it might have reached here but then because, after the construction of dams, people started construction near the riverbeds, they change.

So, for instance when we say about solutions, how to retrofit it, what are the techniques one can use. For example, in architecture we might have studied shoring and you might have studied about raking shores and you might have studied about underpinning so, these are various techniques which we learn from our architecture building construction subject but then this is one, where you really apply it because this is where, in order to protect this wall and during the restoration process, you need to apply these shores.
