Hesamaldin Moeindarbari

So what?

Messaoud Saïdani

It is just a type of construction, like suspended roofs... it allows larger open spaces

Arbab Faisal

What's the main advantage this type of construction?

Arbab

Some of the advantages, I think, are:

- allows larger open spaces (less columns are needed)

- economy in material use

- aesthetically pleasing

Disadvantages:

- design is more complex (including that of the foundation)

- savings in materials could be offset by more costly design
