I do not support additional floor(s) during construction stage without structural redesign and checks to confirm the suitability of the members.
However since this floor is to support the solar panels only , you don’t need 20mm bars for the columns, instead use 16mm as your second to roof level columns reinforcements and also ensure that you stiffen the panels with reinforced concrete beams.

Let your structural engineer design the roof slab and beam, the thickness of your slab should be at least 150mm (6inches) or as designed by the engineer.

dannie007:
Your Structural Engineer is Correct! All you need is a good Concrete mix ratio and a Good Iron Bender who is Experienced to handle the reinforcement steel. Most especially the stirrup need to have a Hook to hold the 16mm Rods in the pillars to withstand Load Bearing.

Thank you

Guys I need your help, my engineer is telling me that my foundation will be this tall due to swampy area, I am scared of the amount I will spend, any suggestions please

For safety sake don’t do heavy pop design under deck! Make it moderate!


Make sure you use the right materials as well to avoid story like the one in this video

I think Polystyrene pop will be better in this case since it is way lighter. I am really considering using it for my house, except in the kitchen

Please what's your reason for excluding the kitchen, if you don't mind?

Maybe the material is flammable

Balistic4:

well, just my personal view, it is a soft material and kitchen can be hot for several reasons. So to further ensure that there won't be any fire incident, I want to use normal pop for the kitchen and also ensure that all the wiring in my house will be with thick and quality cables to avoid electrical heating and sparks. This is just my thought, haven't done that yet. Advantages of using polystyrene are just too much to ignore, especial the fast deliver, light weight, and cost.

The purpose of using mm in measurement is for precision. When you begin to have only zeros at the end of every measurement, it does not show precision and lacks attention to minute details.
I would trust a workman that gives a measurement in mm for say 458 x 1189 than another that gave 460 x 1200 for the same window space.
We know plastering will take care of that small difference but again, perfection is always good.
This inattention to little detail is why a window flew off an aircraft midair recently.

How do you fix yours?

The best practice for decking is to nog the decking with 2×4 or 4×4 and attach/tie the pop to the noggin instead of gumming it direct to the decking. It is a lot of work noggin a decking but it is worth it on safety grounds.

Rany4all:
Yes kitchen can get quite hot, but I don't think it can get hot enough to melt or burn a polystyrene ceiling though.

One of the many uses of polystyrene is in making food flasks or water bottles in other to keep foods or drinks hot or cold. If polystyrene could melt so easily from kitchen heat, then I don't think it would stand a chance when exposed to a hot food or drink.

saydfact:


Well...
Its not professional to have a dimension of 458 x 1189.

And mm isn't used because of precision.
It's a British standard used only by British and those they colonised.

Eg America and China don't use it, do we then say they don't have precise measurements?

Since I have been using micrometer screw gauge here in the US , it has always been in mm.

The International System of Units, universally abbreviated SI (from the French Le Système International d'Unités), is the modern metric system of measurement. The SI is the dominant measurement system used in science and international commerce

decatalyst:


Mind sharing the pictures?

OnMyHonor:


I think there is a little "mix-up" in what @Saydfact was trying to say.

"mm" is an SI Unit of measurement of Length, just like Kg is for Mass, Seconds is for Time, Kelvin is for temperature, Ampere for Current, Candela for Luminance, etc.

SI Unit stands for "Standards International" Unit.



So, it is used by all Countries, as an International Standard for Measurements but Countries also have their own unique standards of Measurement, which are also acceptable and widely used in those Countries.

Woods get weak or eaten from the inside, by those bloody Wood Ants, despite treating the Wood with Solignum, before noggin!

Another [b]Option, if someone knows they are doing POP, the necessary thing to do, is to provide 10mm Iron Rod Ready-Hooks embedded in the Decking, at the Concrete Deck Construction stage (like we do Fan Hooks into the Decking at that stage), you can now hang your Pop to such hooks.[/b]
No matter how heavy or how much you attach to it, it will stay-up like that, as long as the job is properly done by a qualified Installer and they use adequate Cementing/POP material.

OnMyHonor:


Wherever you use Polystyrene, the danger of its high flammability will always remain.
In my opinion, it is better to restrict Polystyrene use to Parapets, which is mostly outside the building and high up there.

And l think the high density versions of it, can be used in Rib Slab Decking (instead of using Concrete Blocks), to make the Decking even lighter and because it will be encased in Concrete, the risk of it catching fire is highly limited.

In Houses that have Concrete Decking, as Roof (Over-flows), the Polystyrene can also be used to do such Decking, by encasing them inside a Rib Slab Concrete Decking, this will reduce weight of the Decking and also keep the inside of the House cool, by refusing to transmit the Sun's Heat inside.
You need to sleep inside a Room that is decked, to appreciate the level of Heat it gives-off, in the evening.

Using Polystyrene as POP in the Bedrooms and Living Rooms for example, will result in lighter weight but we still have to "balance" this advantage, over its high flammability.
If you have a choice, l would say: please dont use it anywhere inside the House.

Polystyrene Material should not be anywhere near a Kitchen, just like Gas Cylinders, in my own opinion!
Yes, it is used to keep things Warm/Cold, that is because it is not a good TRANSMITTER of heat and forms a Heat barrier on each side.
But Heat and Naked Fire are two different things.


It has a very low flame-point, it is made from highly flammable HydroCarbon Chains of atoms (we actually make Gum out of it, by mixing it with a little Petrol and the Petrol just melts it like butter).
If it ever comes into contact with a little fire or hydrocarbon solvent, it flames immediately.

Kitchens are that area of our Houses, where a fire is most likely to start (ordinary frying Doodo without paying enough attention or just warming the Oil before putting pepper or putting pepper when the oil is too hot, can result in a fire!).
So, l think it is most important, that we do everything humanly possible, not to put anything that can aid the fire, around the Kitchen Area.

As for me, l specifically use concrete deck as the Ceiling of all my Kitchens, even upstairs!
If a fire starts from a kitchen, the Concrete Deck will prevent the spread of the fire to the Roof (at Uppermost Floor) and give you a fighting-chance, some minutes, to activate your Extinguishers.
But if the Kitchen Ceiling is made of anything Polystrene or Plastic, you might not have those vital minutes and it may actually fuel the fire.

Why would l take such risk, when l can avoid it?
Well, l was just thinking aloud.

Rany4all:
All I see here are unfounded fears bro. Next thing we'll hear is that we shouldn't have PVC ceilings, wooden furnitures, clothes, curtains, gas cookers or even electricity in our homes. Forget whatever you've read on Google, polystyrene isn't as flammable as you guys portray it to be. Ceiling that is up there, 3 meters or so away from any naked fire from your cooker, will now suddenly catch fire or melt away and the shirt you wear or your hair never first catch fire Haba

There are so many more things that can cause or spread fire in your home. The key thing is just to adhere to building codes and fire safety regulations. Dazzol
