U should know less considerations are given to ventilation & lighting for hotel designs.
Have u seen bathrooms/wc without windows for residential buildings in nigeria?

Not done in Nigeria, does not mean it can't be done. It's a matter of choice for use by the individual.
I remember, I have seen a toilet without window in a family friends' 2 bedroom apartment. It's a guest toilet though.

Rubbiish:
U just confirmed my suspicion
Ur design is an imported one
Stop comparing nigeria architecture to foreign arrchitecture, we don't have same weather, so don't expect same design approach...

just one question & do answer with sincerity;
Are u an architect trained in Nigeria?

There's a 3 storey built hotel in Edo State where the toilets as designed don't have windows but vents.
The architect who built it is not same as the one who designed it.

skimanski:
Also the clients should bring the design too. Let’s even start from there. Because non of my clients have agreed on a design with such a cantilever.

Anyway I Dey wait for @Egunmogaji . I believe say me and my Oga go do this kind of building together one day.

Every client is supposed to bring his/her design. It is the duty of the Architect/Engineer to make it work-able to the best of his/her intellectual capacity.

Rubbiish:
@bold So all the structural designs done by our structural engr. were given to them by the architect who designed them? Why must the architect be the one to get the structural engr in this case?

In an organised environment Architects put up designs (drafts) for any structure/build of any type and the Civil/Structural Engineer comes up with the structural aspect of the design.
The duty of the Engineer is to bring to reality the idea of the Architect and that cannot be compromised given the right materials for use.

Rubbiish:
@First pic, the cantilever no be here ooo
Can our Nigerian engineers pull such off...I seriously doubt...

Architect who pulls up such design should be able to get a Structural Engineer who will put up the structural aspect.

So it is not beyond the limits of the Nigerian Engineer. It is only beyond the limits of the individual thinker.

oyb:
proper compaction /sandfilling with suitable material/ providing a hardcore base is what is required to prevent settlement

I do not think doing that will prevent settlement entirely.
Every soil type comes with a recommended foundation type which also depends on the structure to be constructed.
Doing your foundation/footing appropriately is paramount to the existence of your build given the right type and use of construction materials.
Bottom to top and vice versa, walls run on the foundation lines except in instances where partial walls are done.

InvertedHammer:
Evidently it boils down to greed. N4000/ton x 30 == N120k.
Add N50k for transportation. It becomes N170k which is close to price in the North and SW. But the suppliers want N270k. Difference of N100k (not including yoshi). The level of greed I witnessed in the SE is preposterous. To get things right, you just have to do it yourself.

\

Good day Sir
When you say price close to the North, please what's the price up North?
I have bought 10 tyres tipper fully loaded in Keffi-Nassarawa State for no more than 80k and can't remember the price for same in Makurdi-Benue State but the difference between both is not far fetched.

And I know the quantity difference between the 10 and 16 tyre trucks is between 8-10 tons and that varies from truck to truck given the size of bucket(s) for trucks and expected quantity to carry.

ceelog:
On the two occasions I ordered for granite from Okigwe (Uturu precisely), on arrival my Engr and casters confirmed it was full load (27tonnes as requested). No complains since then. Paid 50k for tport. #GoodEnoughForMe

I think you misunderstood me.
Everyone knows the price per ton of it. Just factor in everything and the topping goes to the supplier.
The only areas I know where 270k is quoted for 30tons are Rivers State and Bayelsa.

I would very much like to know which other areas goes for that price within the East or West.

ceelog:
That quote is too much. In Okigwe, a tonne is 4000N while tport and fees to Owerri is 55k. So looking at 180k max

I can't say which or what is on the high side. The underlining factor is not being short changed the material quantity supposedly requested and paid for.

How much do you think it would be to pay a supplier who actually escorts a truck from Ishiagu /Akamkpa to Port Harcourt given the number of road hours in a truck accompanying the driver and motor boy making sure there's no yoshi along the way?

spyder880:
I wish I have samples here.

The white coloured granite are of two types. There are the very hard crystallised granites that look shiny and very tough to crush. There is also the ones not yet fully formed white types that may break under physical pressure. There are ones that act like chalk, there are those that are light weight. My attention was called one day in a nearby site, of chippings that float when placed on water!

The black granite are good, but look for the best types. Some quarry at Ezillo has low quality chippings. We like buying from Abakaliki. The best are from Ishiagu, or Uturu areas.

Whether black, white or mixed, look for very hard granites that are shiny and looks like they have precious stones inside.

I do usually pick mine from Crush Rock/Ishiagu.

I will pay more attention to shiny crystalline surfaces.
Thanks for the insight.

spyder880:
There are many chippings quarry sites in the south east but concentrated in 2 states of Ebonyi and Abia states. I have been to over 10 of such sites. Enugu has only strong brown stones.

Okay.....Ebonyi and Abia.
In other circles, certain engineers prefer the white coloured granite against the dark type.
What's your take on it as it's suitability for concrete works usage?

InvertedHammer:
Is there any "tested and confirmed" foolproof way to prevent this scam?

Bixton: Getting another supplier may not be the solution because there is no guarantee that it won't be another scammer-in-waiting. How long do you intend to do this until you get a trustworthy supplier?

Nigeria is indeed an "interesting" place for transactions.

Is there a reason (other than greed) for the huge disparity in price between N/SW and SE/SS. 30T granite in Lagos is N145k. Right? But in the SE/SS, the price they are quoting is N270k for 30T.

\

There are no trust worthy supplier(s) at least not in construction business. One can only minimize his loss through careful bargaining.


There are natural granite pits in the North, West and East.
The pits in the South South (Edo/Cross River) and South East ( Enugu/Ebonyi) serves the rests of the states within that geographical location. Once one is able to factor in the transportation cost of conveying the material to his site then there goes the disparity. Also there is the issue of geological material type and it varies.

I am not too sure of the price in the East. But there is a wide gap when compared to the South most especially Rivers State and Bayelsa.

But do people still buy at 270k for 30tons in the South-South. Please which precise area in the South South is that?

Chekitaut:
30tons Granite will use 100bags of Cement on 1:2:4(standard)

A 100 bags of cement for such is a good stock.


A 100+ bags of cement is in the right direction.

If you believe and have evidence that you have been ripped off by the supplier, what will be the solution?

There comes one more headache in doing business with Nigerians? Who can be trusted?
/

In the instance of no established guidelines between I and the supplier, i'll just get another one.
In the instance of established guidelines, the supplier will be short changed during payment.

Chekitaut:
The white & Blue truck is 29.78tons, i can not place my hand on the waybill where i am now.

Below is less 20ton or 22tons max load.

Given both tons and trucks for those actively engaged in construction works, the best way to know the right quantity is in the usage for concrete works.

How many bags of cement is one supposed to exhaust given any of the nominal mix ratios?
If you are to believe that your supplier has not short changed you.

Who can guess what these folks are doing with the shovels on top of the delivery truck?

I hope it is not what I am thinking.

They are trying to spread the granite well so it will balance the truck for easy movement.....

Any idea what's the tonnage of this granite.

adeyanwale5:
thanks YAK...


i need simple designs for 2 bedroom flat and 3 bathroom ,
plain land and;
the project location is Niger state

You can get a good design from Darenyx. Just sought him out via the search option and discuss the terms with him.

Please how many blocks will complete a 3 flats of 2bedroom from bungalow to lintel ??

If you have the design plan kindly post it here, you might be lucky to get a feedback.

Soakaway done by https://www.nairaland.com/abdulwastecx

https://www.nairaland.com/2354065/nairanlanders-building-project#34368855

THANK YOU SIR.
You have tried and I like your technicality.


Rafts are NOT baskets.
Yes, it serves its purpose but it is not same thing as a basket.
Technically it serves its purpose as a column base but cannot be likened to the usage of a basket/column base.

The reason behind using a basket as column base is entirely different when a raft is recommended for use.

A raft is not a substitute for basket as semovita is substitute for garri.
A sketch is not same as a drawing.

KolaShangOne:
The first pic is a bungalow. You can see the pad foundation dug.

2nd is also a bungalow. If you zoom in you can see the mat.

I am very certain this bungalow comes with a concrete fascia/parapet and that is highly not in contention.


THIS Major Argument is in Doing A SOAKAWAY....................
If there is any ENGINEER here to have done soakaway with basket/column base/column, please present your picture(s).


If it's because of me and any concerned follower that any ENGINEER here will immediately attach a basket in his SOAKAWAY design construction please I am only asking for a picture.


SOAKAWAYS are NOT bungalows.

Thank you.

KolaShangOne:
Bros, I actually have. I'll just need to dig deep into my Gallery to get you pictures.

All columns should have a footing to spread load. Because it's not done sometimes doesnt mean the not doing it is right. I assume you're an Engineer too.

You know how point load exerts force on its surface area and how a uniformly distributed load also exerts force...

Good one.
I would very much like to see the picture(s).
Patience cannot be exhausted.

Thank you.

Daboomb:
If l may contribute:

Columns need a Basket, so as to reduce the 'punching-effect' (Pressure) of the Vertical force (Pressure = Force/Area) it is carrying.
This is a fact we should not even be arguing about.

Now, since the downward acting force is what the basket is "designed to reduce", you will all agree with me that if that Vertical Force is "negligible", we can as well do away with the Basket since it is designed to "spread that Force" acting downwards, which has now been said to be negligible..

This is why Bungalows of the olden days dont use columns, not to talk of adding a basket to the columns!
Those Bungalows have stood for almost a hundred years and all the rain and thunder of many decades has not collapsed them but we have newer building collapsing even before they are completed!

In essence, if the Vertical Force is negligible, you can do away with a column (as shown above) and by inference, do away with a basket.
Your house will still stand (and the obvious reason for that, is that, as they do in the olden days, you would have used "standard blocks and mortar-mix", to erect your house. Not th fake blocks of today).

So, using a basket, being for a reason, is not given.

And that brings me back to the origins of this current discussion: using basket in the columns of a Septic tank.
As l have pointed out above, it all depends on "how much vertical force" you envisage and therefore, have the intention of spreading.

With particular reference to my able builder, Abdulwastecx, if you are building a septic tank in some places, where the ground is unrepentantly very hard, the use of columns is an 'over-kill' and waste of money because in such places, l have seen such tanks built with just blocks (no columns at all) and they have stood there, doing their job for over fifty years now. No collapse!
Why?
Bceause such structure is carrying negligible wight and therefore the 'Vertical Force' (from Pressure = Force/Area) is also very negligible.
There is virtually nothing, in terms of "Force" to spread (which is the job of a basket! You wont spend moneyand effort, just to achieve nothing, would you?).

Thus, when someone says you can do a column without using a basket, the next question should be "what weight is that column carrying"? Is such weight/Force Negligible?

And l guess the man asking for "drawings" is thinking along that direction (Such drawing will show the 'Weight/Force' being carried, that necesitates the use of a column and hence, a basket).
Columns are not just for decoration, they are an engineering, structural functionality in a building though a lot of 'enthusiastic' builders just use "guesswork" to throw columns here and there, even where they are not necessary, not functional and a total waste.

To say all columns must carry a basket without being specific on what it is acrrying in terms of 'vertical force' is like saying all cars must have a cooling airconditioner or HQ-Surround Sound!
if it has one, good for the occupant.
if it does not have one, it will still serve its purpose of just taking the occupant from point A, to point B (but inside this heat ehn, dem go confess their sins sharp-sharp ) if that is all that matters to them.

Let us not turn this into another bric-brac (as l see it going, if we dont stop now).

Both sides of the arguement are correct but they are both arguing on different things. No congruency at all


Anyway, wetin l know sef.

Boss man, you know every every.
Engineering principles are not in contention here and Engineers don't assume.
As long as engineering /construction materials contains requisite physical and chemical properties that is satisfiable, they are usable to serve their intending purpose.


What one has not done or seen clearly to be carried out let him not put a claim.

A picture is worth more than a thousand words.

skimanski:
Those are pillar positions

Okay Sir.

The main discuss is about using baskets/columns for soakaways.
Let's not try to deviate. Let the professional engineers put up their design plan for the soakaway they have done. You cannot neglect such in your building plans. That is the primary discuss now.


Using engineering facts to give reason for the wrong purpose is not good.
When one intends to consider using the cast slab of soakaway for car parking then he should use Y16 as columns instead of Y12, if you want me to take your view, hook line and sinker backing of load transfer and bearing walls.


Your use of basket/column for bungalows is not in contention at least those buildings carry concrete facial (parapet).
This is secondary.

snakebeat:
Hahahahahaha
What do i stand to gain in all of this??
U that have been building coulmns for bungalows without baskets, na soakaway u go for need basket??
U can continue doing it your own way...
A word is enough for the wise...

Thanks.

snakebeat:
You will never learn!!!!
Haba!!!!
Column is column, same principle applies to all type of column construction.
I honestly sorry for your clients if u are a building professional.
This is faceless forum & there is nothing to be ashamed of here
Any vertical stand must have a base, including water tank stand, it maybe small, but there must be a base. If truly u have been building bungalows columns without baskets then i honestly sorry for your clients. It isn't a must to use columns for soakaway & bungalows, but if u want to use it, then do it well. I was expecting u to acknowledge your error & move on after a poster pointed it out, but here u are trying to defend something wrong, the more u try, the more u exhibit your ignorance about construction works. The only difference between duplex columns & that of bungalows is that the basket of one is wider than the other, but they both require baskets. If u have been building columns for bungalows without baskets, know now it is wrong.

I will assume you're an Engineer or some sort.
Kindly put up the design plan for soakaway done to back up your fact.
That is how I want to learn so I can properly inform my clients the reason why I would want to start using baskets for soakaway construction.

If you want to quench my ignorance put up the design plan made for a soakaway as you have always done for your clients.
Thank you.

There is no proof of a basket being used there.
The actual engineering plan for the soakaway will put to rest this discuss.

Any one with pictures kindly post them: building basket /columns for soakaway.

It would be easier if anyone can upload the design plan for the soakaway he did for those who have detailed designs.

On a thread on someone's build I did not see columns used on your soakaway since your people refused to put them but instead used concrete to fill up block holes.

skimanski:
Concrete Blinding for Floor

Good day Sir,
Please what's the reason for the areas where your trench has step down?

diordaves:
The fact that you have done soakaway columns without basket doesn't mean it's right. Mind you, basket and columns are not two separate things. They go together. Columns without basket is cutting corners. It's not best practice.

I will take it that you do that for bungalows thereby not cutting corners.
Thanks.
It's a learning process.
