thanks a lot, you're one of the few if not only other builder here that approach issues with a realistic and down to earth approach making use of locally available and widely used techniques instead of the television type packaging that others often adopt. i hope you're enjoying anambra? idemmilli is a nice place although I'm a bit worried about the gradual emergence of Lagos like levies and extortions with the associated omo onile mentality.

i hate the bad blood, hypocrisy and backbiting on this thread.

please are you familiar with building practices in Niger state? we often use gravel (locally referred to as concrete sand) only because of cost and i haven't seen any negative results but here on nairaland it's exclusively granite. what do you think of it?

lastpage:
Please do. You wont regret it
I did same not too long ago ....No Sand at all.

It was excellent but ensure that it is well-mixed since the absence of Sand would mean that only the cement will act as the "binder" to the stones.
You will then have to strike a balance between "Cement" and "Fluidity".

My Builder was saying the Cement is enough but l also reminded him that the "binding effect" is equally important otherwise, cracks will develop during curing.
Its all about the "Science"

It is like a decking, in terms of being self-supporting (after the initial bamboo/Plank support have been removed) at the end of the day.

Even the "Computer Design Software" that generates these designs and calculations, is written by people "Who can first CONCEPTUALIZE WHAT THEY WANT TO ACHIEVE..... put it on paper and then convert it to a software program!

We need to start thinking "out of the box" and not just doggedly rely on what is already available. That is how we innovate.
There is a "process and workflow" to such procedure.

That you think it is not possible, does not mean it is not possible, its just that as of now, YOU cant figure it out yet.

There Is This Spiral Staircase I designed for A Client in Abia-state,The Information reaching me says,The joiner who is to cave it out, lacks the technical know how.with regards To dimensions,and it's procedure,So i'm heading down to Abia state sooner than later,i would Loved the professionals herein to enlighten me on how To go about it, if i should be the one to surpervise the Joiner,any useful information will be welcome.Cc All professionals.let me upload the perspective view.showing the inner casement/situated staircase..seems they are trying to Introduce a standing re-inforcement pillar under the stair.thereby reducing it's beauty.

I asked about in-situ in my post.. You can check again..

KolaShangOne:
A Nairalander complained about about his 'decking' vibrating.. It's obviously as a result of inadequate beams. I've seen houses here on NL where the builder was trying to use 'in-beams to cover up for not having adequate beams on his project.

Secret beans are meant to provide added support over a longer span, not replace beams.

My Oga's in the house, what do you think?

KolaShangOne:
I was referring to d cost of the Poly facial when I said 5700.. I added the cost per sqm + transport +labour + tentative cost per sqm of roof beam and divided by perimeter of 120m..
I now asked how much in-situ will cost (not precast) and hr said 4000 per sqm. I was a little bit confused too because the Ploy facial is supposed to be cheaper than In-situ as Abdulwastecx said earlier..

@Segcymoor The owner is obviously trying to reduce cost..Laterite that quantity is not up to 16k.. Must be an Ijebu man.. (Apologies to Ijebu men here)

Onuokwu:
I like your threads but you don't always show us the completion. You tend to abandon it midway.

Is the finished article pleasing on the eye?
Can one spot the difference a mile off or is it hard to tell the difference? Is it a strong enough to resist our hard weather conditions? heavy rain and ghastly winds?

johnson232:
Thanks for the explanation sir, so one just need to attach the polystyrene to the roof beam. Does it require much columns like other parapet? Cc: abdulwastecx

KolaShangOne:
@abdulwastecx When I added the costs, I arrived at about 5700 per sqm for the Polystyrene fascia.. How much does the in-situ fascia cost per sqm so that we can compare?

mufutau55:
The wires were already incorporated into the Polystrene fascia for hangup. The outer side is also already coated with cement from factory for more dressing. I have had lengthy discussion about the installation and the Polystrene itself even before he posted it here.
It's a very good alternative to insitu and precast parapets especially because of the weight; you don't need columns (pillars) to install it.
You will still need need the last beam (for roofing) to be installed after the Polystrene. There is some cement to be casted while installing the Polystrene to hold it in place with the pre-incorporated wires and the roof beam will totally secured the Polystrene.
I did not want to divulge much information and will rather let Abdulwastecx come here to explain it in the building jargons.
I am sure he will post more photos like the ones he sent me on whatsapp for private lesson/discussions, I am sure he is reading this too.
Thanks.

good analysis sir

lastpage:
Thanks Hajji, for your contribution.

What l am looking at, from the picture and what others have observed is that:

1.) It does not look too tidy, after installation, unlike the "casted" one, in-situ or otherwise.

2.) Going by the "materials listed", you still need a fair amount of Concrete Mix, to hold it up there, even as it is not weighty and should not need such Concrete mix to stand in its place. Why is this so?

Can we not find a more efficient way of "hanging/installing it" on the Roof Wall, without going to the extent of mixing concrete?

when l was small, a very heavy storm blew away the roof of a house l was in and on inquiring from ma parents, l was told the roof was "not tied down" with those metallic strips that is usually used to tie a bundle of Roofing sheets (Oja'agba, in Yoruba).
Nowadays, most houses dont even use that but have devised a better way to tie down the roof, without affecting the aesthetics, as was the previous case!

3.) As something made from PVC, the price still seems to be on the high side!
I assume, using a mould, this thing is a product of "melting Plastic granules and pouring it into a mould and/or extruding it.
"Iff' l am correct, then it should be no more costly that an equivalent amount of "plastic material" (in-terms of materials used and effort applied)

What if l suggest that they put a threaded iron (like a very long iron screw) into it during manufacture and we simply either screw it down on the top block (and chuck it with a little cement to hold it down) .... or insert anchors into it during manufacture so that all you do during installation is simply "Hang it" on the top wall?

Since it has no weight, hanging it will not be difficult nor will it have any gravitational force to pull it down.

Just wondering aloud.

Oga Abdulwacstex should please come to the rescue o!

@abdulwastecx

Please lecture us more on this, you go work for Benin-City? Thanks

mufutau55:
This is what I and you have been talking about it. If you are the one installing this, please provide us with installation pictures and costs plus other relevant helpful info. This may be a good alternatives for not so heavy parapets.

Hajji M.

EgunMogaji:
How heavy are this and does it still need pillars?

Thanks for sharing.

I know you are always very detailed on your offerings and I look forward to reading it.
