@Bolded...what happened to your project in Ogidi and the bungalow in Anambra state. Have you concluded with them? Can we see last pictures of finished houses if the owner will permit.

As you can see that the bungalow is in the same compound as the duplex but since the duplex is a family house (my client don't really want too much publicity) but since he is also a silent observer on nairaland, he didn't object us having it here.

As you also observe, our work is done stage by stage. We signed agreement after each stage, if the client is happy with our previous job then we sign on to continue the job and if we are not up to scratch we look for ways to get it done properly before we proceed.

Here is the ogidi bungalow

Here is the anambra house you asked for.
We left the site December after we finished the plastering, we will resume work this month. due to hammertern which causes shrinkage, we decided to wait a little bit for the hammertern to go before resuming work.

Work slated for this phase are
1. Fence plastering
2. External wall rendering
3 . security house.
4. Completion of the garage etc.

More block work updates: we intend to get to four courses for the first day room

Block work : for this bungalow we are going to be using 9'' block throughout out.

I am enjoying and learning some things here, keep the good work going engineer, thank you.

Thanks sir... we are your boys, coming up like you sir

Oh! I see! That's so lovely to hear.
From a book I read, Elements of Reinforced Concrete design (can't remember the name very well), Engr. V. Oyenuga made some statements about using load bearing walls. One of them is, It must be machine made and each bag of cement should yield a maximum of 25 blocks (though I know it shouldn't just be 25 but should be within that number to obtain a good strength). He also talked about the Bearing Capacity of the soil ranging from 150Kn/m^2 ~ 200Kn/m^2; and from your explanation above, it's like the soil BC met the requirement. Now, what quantity of the Machine vibrated stone dust blocks are formed from a bag?
Are your blocks made on site under your supervision so that the desired strength/number per bag would be achieved or they are made away from site? Because, I know most of these block industry guys are always after their pockets, not considering the required strength to be achieved.

Sorry if my questions are annoying. I'm just a learner trying to building my CE experience.

Nice sir... I am very familiar with oyenuga ( the Yaba tech, doctor). In that reinforced concrete design book you spoke about, the man was referring to load bearing partition wall and in structures, a load bearing wall must carry a reasonable load like slab, heavy roof, canopy beams etc.

The bungalow we are building here will only carry a head beam of 225mm x 225mm and also very light wood truss. Having say that it is still important to build according to some standard. We bought the block from a trusted supplier that uses stone dust to produce block and he get between 30- 35 for every one back of cement, properly vibrated and cure for some days before the work. We use this method because it will not be economical to mould ourself with the vibrated machine for such a low quantity of block we want to buy.

Bearing capacity only affect the width of the strip footings that will carry the load bearing wall but this affect heavily loaded portion wall. Thanks

EgunMogaji:
Do you use it on all your foundations or there is something specific about this lot that was of concern?

Thanks.

PS: ultimately, m trying to decide if I need to do same.

I use it in all my work sir because it help prevent a lot of future wall pilliing and it is cheap. It cost me like 10k to get all all the plastic for this project

EgunMogaji:
I might have misused the acronym dpc.

I meant the black plastic covering.

That should be DPM (damp proof membrane). It is use to prevent moisture rising through the foundation

EgunMogaji:
My oga why did you use dpc specifically?

Because I want to achieve something reasonable
1.i want to have a uniform level on which my super structure will be built
2. I want to prevent moisture rising through the foundation
3. I want to have good platform on which floor rendering an tiling work will rest on

karleone:
Abdulwastecx, I didn't notice any sign of reinforcements used esp. with regards to columns. I've heard of columns not being necessary in bungalows and load bearing walls (1 storey) buildings, but I've not really come to understand the reasons why. Could you please explain why.

Ok sir.
I have made it a policy to build all my structures ( either bungalow or duplex) as frames structure ( building where there are columns and such columns carries all the load rendering the wall to be just partition wall) since most of the house we have been constructing are in the east or south South, where the soil is relatively soft.

For this particular project on a relatively good terrain (suleja, niger state) and couple with the client limited budget we decided to use load bearing block wall. The block use was machine vibrated stone dust block with reasonable strength. That is the reason why we use 9''block throughout this bungalow.

Onuokwu:
I notice that you did not use rods to reinforcethe dpc before casting. In another thread you had said that this was necessary. https://www.nairaland.com/2762704/construction-3bedroom-bungalow-somewhere-ajah/1

What is the fine difference before the two foundations and reason for deciding not to use rods in this one?

That thread, if memory serves me well the builder specifically States that he is building a 'raft foundation'.
The use of iron mesh is important, it add more assurance and protect the foundation when not properly compacted.

We decided not to use iron mesh or y8 for variety of reasons like
1. The fill is low and fully compacted.
2. The building area is relatively small
3. The mass concrete will do just fine without mesh or light reinforcement

Miscellaneous:
Pls wat is a formwork ?
& can we say dpc is part of a foundation even though is kind of a floor ?

Forgive my ignorance.

GGMUB bro.

Formwork is a is a platform use to enclose concrete in a civil engineering/building construction. it is a temporary structure that serve the above listed purpose a d it is removed (striking) after the concrete as set.

For this foundation, the Formwork is that wood that is nailed to the edges round to get a reasonable height, level and to hold back the concrete.

Dpc is an oversite concrete that is part of foundation but place at an height above ground level.

The dpc is 5'' thick at maximum and 3'' minimum. The mix ratio is 1.3.6

Summary of materials used

More updates from the foundation

Compaction of filled to achieve a very rigid foundation.
The compaction was done by water g the foundation for ten hours after which a very heavy manually made rammer is used to compact the foundation to the required level

EgunMogaji:
In the meantime, my builder is suggesting a 3" german floor for the house part and 4" for the garage. He suggested it as a way of cost saving since this is supposed to be a budget and fast garage apartment build.

I don't think I've seen one on here yet but I might be wrong.

What says yee of vast experience?

My oga If you are doing a garage you will need to design the floor . This will translate into about 125mm( 5'') concrete, minimum of Y8 spaced @ 225mm (10'') center to center after the floor has been fully compacted. I have some pictures I will share with you

[quote author=Slim101 post=42536771][/quote]I am currently in ilorin, when I get back to Abuja I will help you get a realistic estimate my oga...

Okies27:
. Have read through many comments and non seem to say anything as regards how the Bible admonish us to conduct ourselves both in worship and our everyday life. No where is it written in the Bible that medicament is bad. The Bible talks about plants being for the healing of the world and most drugs are from plants. As for discipline with, I'm sure a lot of here can say the cane corrected some ills in us but everything should be done in moderation. Spare the rod and spoil the child the Bible said, don't ask me where is in it, search it out yourself cos that's why the Internet(e-bible) is there. No fan or ac in church isn't a practice OP. Some of your writeups are without proper checking of facts. Don't deceive people please, and of your reading this, read the Bible yourself and make reference to the book whenever you feel uncomfortable with a teaching.

I don't need Bible to tell me to be of good conduct, to be peace loving or to respect authority.

The Bible was written when for centuries other civilization have perfected the use of herbs and people have the knowledge of Medicine and believe they were from plants. The Greek, the Roman, the Egyptian, the Chinese and India practice medicine using plants predating Christianity.

European, North America (Canada and usa) and far east Asians are the least religious people on earth and at the same time the most developed religion.
They don't run to pastors when there is a flood, or epidemic. They go to the lab and research centers to get solutions to their problem.

During ebola outbreak no Nigeria pastor travel to guinea or Liberia to heal people

A lot of white Christians advocate for child abuse.

There are some who argue that it is okay for a man to beat his wife.

A lot of parents in Europe and north America do not like their children watching TV, both religious and non-religious. TV is a programming tool and largely a waste of time.

I disagree with you on your last point. Television is good for children when they watch good contents. Good contents like adventure, news channel, education Channels, foreign affairs and rated movies, but things like African magic, all music channels and religious channels destroy their ability to think critically.
I don't want my daughter to end up looking up to Tina savage as her role model but I want her to see the world around her, to understand stock market, global politics, her history etc

Every society passes through stages. I must say the western world is 300 to 500 ahead of others. Even the western world passed through what we're now going through. One of the examples that really changed things in Europe is the French Revolution of 1789
Africa hasn't reached that stage of scientific enlightenment but we're heading there.

You don't really make any sense. I don't know what is special about your so called western world. The so called western world were killing, raping and destroying civilization as early as 400 Years ago. Spain was a third world country as early as 70 years ago.

Religion is a disease that courses people to lost their thinking faculty, it causes slavery of the mind and destroy people use of logic. We believe in so many white God that we hardly think good of ourself, we kill ourself all in the name of books that doesn't really make any sense from logical point of view.

Pastors take 10% of an average income of Nigeria Christian but the same Christian can't pay 5% to government as tax to help developed infrastructure, provide security. We all blame government for poor service but how many of us pay our tax or contribute anything meaningful to our nation?

How far on this TeamHarney?

We are waiting for the hammertern to go down and for the client to mobilize for the second phase of the project... By God grace, second to third week of February we will be on the site

PeoplesArmy:
True talk. I find that the arrangement of my interlocking stones are now disintegrating because after 15 months of installation, the compacted underlying sand in now settling.

By the way, Abdulwastecx, is the depth of that foundation because the soil structure is good? OK have seen a couple of builders here with same "not too deep" foundation even in areas like ajah etc.

Depth of foundation depends on a lot of things like soil type, water level, height above road level etc. I think this is the most economical considering integrity of the structures for the house

Compaction is very important for interlocks. It must be done in layers for a deep fill and with the help of a roller.

This foundation will be thoroughly compacted by adding water to the filled and manually Compacting with an iron rammer

How is podosci doing bro?

Doing great

EgunMogaji:
If the final picture shows the final coach of the foundation wall them I'm jealous my oga

You'll need very little filling. I've spent N300k (340 tons) on laterite on my "little garage" site

The biggest problem with your type of foundation will be lateral pressure building up on those sub structural wall above ground level. these walls will act like retaining walls and they are not thag strong to retain the filled foundation, this may cause ss them to shift away.

You may need to ring/tie them up with a beam and filled the block below with week concrete. (oga spyder is doing excellently well with in this regard)

Another problem is settlement, most filled experience settlement after sometimes due to poor compaction. The higher the filled the more likely to settle
