Sketch of the plan. No 3d. Approvals cost 135k

EgunMogaji:

I can't quite tell if I'm looking at 6 or 9 inches, please clarify.

EgunMogaji:

Madam, why did you flip the kitchen/dining between the units?

beansandgarri:
I started by moulding 100 bags of cement at 35 blocks per bag. So we have 3500 plus blocks

benpedro:
Aunty abeg do you mind showing us pics of the developments so far

EgunMogaji:


I can't quite tell if I'm looking at 6 or inches, please clarify.

This comes out to be N94 per block, impressive. Even more so if it happen to be 9 inches. Additionally, one would hope that you're ending up with much more stronger blocks but this is not always guaranteed.

I buy 6 inchers at N115 and 9 inchers for N130.

So in Ibadan, you saved N77,500 and N133,000 for 9 inchers.

Madam, please go out to the nearest mall and treat yourself to a pedicure, manicure, massage and pick out a nice new outfit. You've deserved it

Phase 1
Excavation to dpc.
The excavation was done at 3 meters since its a bungalow and the dpc built up to 6 coaches because the land is table but not even. Since the land is not swampy. I decided to do a capping on the dpc and the German floor will be done later.

olumide4christ:


[b]As a professional, I would like to advise you to ensure you completely cast your ground floor slab (or german floor or DPC as the laymen call it) before continuing with your blockwork up to lintel level. Don't use the system of raising the blockwork up and casting the german floor within the room spaces later as I presume you're planning to do considering the capping you've done.

Like I advised "EgunMogaji" on the off-topic thread created by Hajji Mufutau, doing the german floor using the 2nd method which you seem to be proposing will result in 2 problems along the line:

1. Cracks along the edges of the walls and german floor as a result of differential or uneven settlement between the walls and the german floor. This is because in this case, the german floor is not monolithic i.e. the walls and the german floor are 2 different entities and as such, will shift/settle independently. You will now have termites and other insects/pests passing through the cracks into the building.

2. Rising damp - you will begin to notice the walls becoming damp when rain falls or when the water table of the soil around the building rises.

PLEASE TAKE NOTE!![/b]

This is nice....
Is the money for supervision from setting out to this stage?

Thanks...

beansandgarri:



Yes the supervision is for setting out to dpc since it is a pay as you go project. The agreement is 2k a day for supervision. Due to Xmas and carnival expenses I was just dashing the guy small small money .

@bold,correct woman...

In as much as we try not to get ripped off by our builders, I think it is also not a bad idea to encourage and motivate them once in a while....

But this your beans&garri moniker always dey make me laugh...

Beans is sure going to be one of your favorite food...

johnson232:

My brother without wishing to sound judgemental, I think there is nothing wrong with block capping, when it's properly done.

I have seen renowned engrs use this method many times....

olumide4christ:


Well Oga,

That renowned engineers do it does not mean its right.

There are engineers & there are engineers, same goes for architects, QS, it depends on where you find yourself. Any construction professional worth his/her salt & who has a professional seal to defend will surely agree with me.
So I'm sure that the renowned engrs you talked about either are not professional registered OR if they are, they did such foundation in secret Because if COREN who regulates engineering professionals in Nigeria get to know, they will lose their seal & face the music!
I rest my case!

EgunMogaji:


Do you care to share the regulations per COREN that frowns upon the method?

That an association of professionals frown upon a members action doesn't mean that they are right.

Recently in the news an OBGYN (a female specialty) Doctor was sanctioned because she started treating gay male patients because she felt that they are having the same medical conditions as the female patients that she was seeing. Her practice was a success.

olumide4christ:


RULES and REGULATIONS differ from place to place, so what obtains in the U.S. may not obtain over here.

ALSO, do take out time to consult every literature or book written by authors on constructing foundations - in the US, UK, Europe, even here in Nigeria, etc, that system of casting german floor separately from the walls is a NO-NO! You could also ask architects or engineers you know to give you their books or literature on foundations to look through. If you find one in the US where you're based where that system is encouraged or shown, kindly show it to us here; that should clear the air once and for all.

Regards.

EgunMogaji:


Forget the US/UK thing I beg, I am just as Nigerian as you and I'm not foreign (pun) to Nigeria.

Again I ask, do you care to back up your claim that COREN frowns on not doing german floor? It's simple.

It would be an interesting proof to shove into peoples faces whenever the argument comes up which is frequent.

olumide4christ:


No need to give you proof, sir.

Let a construction professional (ARCHITECT, STRUCTURAL ENGINEER, QUANTITY SURVEYOR) who went to the 4 walls of a school and learnt about structures and has professionally qualified in that respect (not those who happened to diversify into construction due to interest or the lucrativity of it) come up here and prove me wrong. Hopefully, they are on Nairaland; at least i know of 'opalu'.

I await them to prove me wrong.

No more comments from me on this issue on this thread till they come and prove me wrong.

erico2k2:

NO OOO dont do it.?ur floor wont be even and each room Will have it's own level.ur German floor is meant to be on top of the foundation blocks. Using it as support.if you go ahead with this plan your room slab will be held solely by the sand undernith.

johnson232:

@bold, the ground floor is held solely by the sand underneath. Blocks can't hold ground floor slab, because it is not reinforced..

Why do u think people spend so much money on compaction, some even wait for rain, because the filling sand is the major thing supporting the German floor....

EgunMogaji:


For sure.

I'm still waiting for Korean or is it Coren experts to submit proof once and for all.

Oh wait, maybe they're drafting up an invoice for me to pay
