Typical standard duty slab on grade is 4".
4m sounds fine but it depends on the size of the space and the level of intimacy you want. |

Thanks teamjdc! Sorry I'm not very familiar with the terms. May I know what you mean by 'Typical standard duty slab on grade?'
And just to make sure, 4'' is 100mm, right? Looks thin to me. Sorry I'm not sure about the details of structures. If you have any detailed drawings I can refer to, pls tell me - that would be helpful. Thanks alot! |

teamjdc is talking about ground floor slabs, which is a fair assumption considering you didn't give much detail in your post.
The thickness of the slabs for the upper floors would depend upon the type of construction strategy and, for example, the span between beams/supporting structural members. As well as the thickness of the floor slab you'll need to think about whether you need to show beams too. Shopping Centres usually require large open spaces between columns. If you don't have beams to support your slab, you would need more columns, closer together!!
Annecdotally, looking at new shopping centres going up in my area, they often seem to use a composite system, a 'crinkly' steel tray with a layer of concrete poured on top.
How is your shopping centre constructed? Do you only require small shop units or will it be the location for large open plan department stores? |

Yeah, I realized I didn't give much detail in my question. I'm sorry about that.
I'm currently doing just a section and I'm not intending to draw in detail. It's not ground floor and yeah I'm only drawing a shop unit. I don't know how to explain how the mall is constructed but the columns are about 1m thick with 15m gap in between.
So I want to know how thick should the floor be in my section.
Thanks for the link, team jdc. and thanks lekizz for that explanation.  |

For the purpose of showing an schematic section you could use a standard 15cm slab, the columns seam to be a bit thick, but again for schematic drawing will be fine, specialy if tne shopping center is a muli story building.
The height of the space probably is 4 meters, to allow the installation of air conditioning ducts and plumbing piping components as well as lighting and electric needs.
It also may require a suspended accoustic ceiling at about +/- 3.6m |

| Thanks for that info, nanrehvasconez! It's clearer now.. Hmm.. Is about 80cm height ok for aircon ducts and components? |

For your SCHEMATIC presentation it's perfect, you will refine as needed when more detailed drawings are required.
GOOD LUCK |
