Judt to add on to the topic... if is rc footing what is the thing that need to watch out?

Hi all,

I have planned to extend my wet kitchen. The area to extend is 18' x 5'.
The problem i facing now is do i need piling or not for single story 18' x 5' area.

My neighbor is extending his wet kitchen also. His contractor told him that the soil in our housing area is soft. And need RC piling to do extension.
If not , the wall will crack since the house will sink for a period. He also claimed that even use kayu bakau also cannot stand for it.

But the problem now is another contractor that i meet up, he told me actually no need pilling, using large footer then already can extend the area.

One of my cousin also is working as contractor, but he is not working in KL area. He also claimed that have no need piling for just 18' x 5' area.
If i worry about the sink, use thicker steel + larger foot is good than enough for it.
So i hope you all can share your experience to me.

Thanks a lot for your advise. Appreciate all the comments.

I also wonder how the contractor install the RC pile? bringing the pilinng machine into the site?  

Hi,
Would like to ask related question to this.
My house extension is as below. The areas I marked with yellow will be double storey extension, the others are not, but will support RC slab. Contractor plan for piling at point A, B and some other points further away. Problem is, neighbour has kitchen extension that is next to point A( he didn't do piling). I am worried piling will cause cracks in my neighbour's wall. Contractor says he will do cantilever from neighbour's footing pad. But I am still worried. Can I get away with not doing piling for point A, only wide footing?

What is KLF?
Between B and 4, there is another piling point. There is soil settling in the region, as the car porch area also had some tiles issue. So contractor gonna go ahead with piling (with cantilever at point A). I am just praying the damage, if it does occur,  will not be major.

Thanks for feedback. Have already discussed with neighbour. Explained that we will fix if any damage occur. Pictures also taken of inside and outside his house before piling.

This is double storey house. I plan extend until End of toilet in 1st & 2nd floor. Estimate about 4 feet. Does this still require piling? Is footing is enough? Anyone does this?
