Hi,

I am building a twin duplex. Recently, I got some pictures and I was surprised to notice that there are not pillars on the pictures.
I called the contractor and he told me that he put 24 pillars on the ground floor and 8 pillars on the first floor as the the first floor will not carry load.

This is really strange .... What do you think?

The twin duplex is 20 m *20 m = 400 sqrt meters

Second thing, he is asking me 320,000 Nairas for the carpenter workmanship for roofing work.

Please help

320 is to high for just worknanship except if the job is elaborate. about pillars, if the structure is just 2 storeys i.e ground floor and first floor, then you can even build with absolutely no pillars. dosent have to be a framed structure.

.

Thank you for your input.

Below is the structural drawing. But I have to confess I do not know how to read it.

Can you kindly explain it to me.

I would like to thank you. You are doing a wonderful job.

Below is the full picture of the structural drawing.

Again many thanks
