Thank you, I get the specific context in which you are addressing this topic and you have done a good job.

The bit that got me worried was the placement of reinforcement in floor slabs.

What you were referring to in the thread is temperature and shrinkage reinforcement rather than structural reinforcement. Only shrinkage/temperature reinforcement requires top placement of the steel. And that would be because the lower part of the slab wouldn't be undergoing a massive amount of tensile stress, because it rests on the hardcore. We would have a massive structural failure and collapse if structural reinforcement is placed at the top section of a normal reinforced concrete slab,

I thought it was worth making this clear because we have a lot of people using this forum as their main Knowledge Base and lives depend on professionals doing the right thing.

Thank you for taking the time to break it down and happy New year to you and the forum family.
Exactly


That’s why we should involve professionals when it comes to structural members

Thank you once again sir smiley

As an aside from purely property matters, and in the light of the undercurrents, and some of the thank you posts here in the last days of 2021 and the early days of 2022, I thought it wise to make the statement below.

In 2019, Bernardine Evaristo won the Booker Prize for Girl, Woman, Other category alongside Margaret Atwood. I watched a BBC program that rehashed that story a few hours ago.

Somethings stood out.

President Obama said that one of the books he uses as an escape from the pressures of the presidency was Bernardine Evaristo's book. Imagine the President of the most powerful country recommending your book.

Bernardine Evaristo has returned the favor she has been granted by been digging up authors who she felt were overlooked and trying to spotlight them and because a Booker Prize winner is the one making the recommendation people were taking notice.

The authors she recommended were extremely grateful that someone of her stature propped them up.

The point is this, if you are a vendor on these streets, be careful what fights you get into, some fights are not worth it. Don't bite your nose to spite your face.

Pick your fights carefully.

Be willing to lose money to make more money in the future.

Be willing to create, sustain and maintain goodwill.

A word, a note, a recommendation can land you a million naira or dollar deal even a billion-dollar deal.

A word, a note, a caution can also deny you a million naira or dollar deal even a billion-dollar deal.

Sometimes you need someone up there to open doors that would otherwise remain closed.

Don't allow people who would otherwise open doors for you to actively force doors that would otherwise be opened to remain closed.

Relationships are the most valuable resource for success.

I do contracts and all of my biggest contracts came to me when someone above my pay stamped his/her foot down and said give this guy this deal.

If people don't like you, they will not deal.

Don't give people a reason not to like you, and then not deal with you and encourage/goad/persuade others not to deal with you.

A word is enough for the wise.

@Charisdesigns

Please clarify the PRIMARY purpose of the BRC in the section. Is it as a binding agent for the concrete against cracks or it is structural?

Your clarification will help me resolve my confusion here.

Many thanks
The primary purpose of BRC wiremesh is adding strength to your oversite concrete. Been made of steel (Structural), we introduce it to oversite concrete to provide strength to the floor, therefore acting against crack.

Take for instance, A place with high movement traffic, or think about most heavy equipment we keep on the floor in our houses (Live loads), overtime fatigue might set in on the concrete, it is the function of the Wiremesh in the concrete to receive and help spread the load

See it this way, Wiremesh serves the same purpose steel bars serves in Reinforced concrete slab.

————————

To the best of my knowledge, the two main reason why German floor is done is to provide
Strength and Act against capillary Action

While Wiremesh along side Hardcore placement, Effective ramming acts for the former, DPM (Damprove membrane) acts for the later

I hope my answer is specific to your question
Good morning and happy new year once more.

Placed on?

I understand the part about not being on the floor.

But the bolded?
First of all, Concrete cover is essential to create a bond between concrete and steel, it also help steel against corrosion and harsh weather. It is simply the clear space between the surface of concrete and the reinforcement steel.

In this context, concrete cover is the space between the ground and the BRC wiremesh.

Wiremesh should be placed at the upper third of the oversite concrete (German floor), This will help fight against shrinkage/crack which originate from the slab top.

While concrete provide compressive strength, the wiremesh provides tensile strength.

The attached is the section of the strip foundation I uploaded previously, the dark straight line under the part labeled “150mm concrete floor slab” indicates the BRC wiremesh and position.

Pics 2: How to achieve concrete cover. Notice the red bricks (biscuit) placed underneath the wiremesh


I hope I answered your question sir

I understand personal preference but You're kind of increasing your construction cost though.

A wire mesh can do the anti-crack work.

***A BRC wire mesh saves time by eliminating the rebar tying process on site. You can spread 1000sqm of it within 30mins. It will probably take a week to tie that with 6mm.

***It also helps to reduce labour cost (money saving)

***Reduces initial purchase cost..
Rightly put

It is really not in the size of the rebar but the placement.

If BRC wire mesh is placed accordingly, it surely will serve it intended purpose (providing tensile strength to the German floor).

Hence,I will be more concern about the placement rather than the rebar size, if BRC wiremesh is just place on the ground(Filing or dpm) and concrete poured, then the intended purpose has been defeated.

It must be placed on concrete cover for it to provide tensile strength to the oversite concrete.

Okay bro. German floor will surely cost more than 90k for a 3 bedroom flat.
Here is my submission about oversite concrete (German floor) some pages back, I hope you find it relevant

It is better to get things done properly now that you are still in this stage....

Doing your German floor now will save you from lot of headache later

From experience here are some advantages we have noticed German flooring have over normal flooring

1) German floor is also part of the foundation, it should be seen as a structural elements that makes your house to stand. Loads transmitted from the building is recieved by the German floor before transferring to the foundation

2)German floor stops the upward movements of water from the soil into your building. I am sure you wouldn't want your walls to be damp or see algae grow on it.

Lastly, oversite concrete can Serve as a breaking point when there is a non major crack to the wall, it prevents this crackline from getting to the foundation.

About the cost estimate, you will have to provide the plan as that will serve as basis for the estimation

Cost
Very expensive

Alternatives

Working principle

High-strength steel tendons are positioned in ducts or sleeves before the concrete is placed. Once the concrete has gained strength, tension is then applied, pulling the tendons and anchoring them against the outer edges of the concrete, before service loads are applied.

Thanks, I appreciate the pep talk.

Now, if one is to construct several blocks of one storeyed selfcontain with each block containing just 4 units, will the plan cover ALL the blocks on the land or will it be for just one block, since the remaining will just be replica of the first?
Since they will be similar and a replica, you can have one design

But then, it is important that your designer(Architect) produce a site plan that clearly shows the positions of each unit on the proposed plot. This will help in proper setting out and also state the clear boundaries of the unit.

Mehn, that your foundation block high, bros. I haven't gotten the design yet, although if I consider cost, I might end up not using one for this particular building.
On the long run, with a good plan, you will end up saving more.

Let me share this about planning generally

Planning is one step in doing things that is really underrated in Africa. White people plan with most of their time and spend little time doing the job with the best approach.
Blacks prefer to get at the job without proper planning, thinking that the time/cost put in for enough conceptual planning would have completed the job. At the end of the day, more cost is spent with a substandard job because of the works that was redone repeatedly. Imagine making a mistake on paper and erasing it, compared to laying blocks and breaking it.

Thanks, yeah skeletal structure. I just wondered if there was any advantage to doing such first. I currently have a three storey building in my area still under construction, but same pattern.

Thanks for the explanation
Effective transfer of structural load across the entire structure. Framed structure will help transfer your loads in the correct order which is (from the roof / slab to to the beams from the beams to the column then from columns to foundation.

When and if a building is not framed, most atimes, slab loads don’t follow that pattern correctly and end up acting on walls (not beams) that is why you tend to see cracks on most walls (especially when they are not designed for such)

Another advantage is in the area of differential settlement, if the building will ever want to settle because of poor foundation, the stiff / monolithic connections between the structural(framed) members will help it settle uniformly. Few months ago, we talked about some buildings seen Tilting (differential settlement)

Good evening everyone, especially the elders, @Mufutau55, spyer880, Egunmogaji and those not mentioned

Please, I've noticed this trend in buildings around me, where the pillars are first casted, both upstairs and downstairs, before block work is done, both external and internal. I'll like to ask, is there a particular reason for such, and can it be done in residential buildings? (Seems most of the buildings that do such are office complexes or stores).

Also, I'll like to know how many blocks are needed in constructing a simple self-contain apartment? It's going to be two selfcontain down, then two upstairs. Then another set, until the plot is filled, they are going to be detached. Reason for this is paucity of funds.

So, I'll love to know how many blocks will be needed for Just one, so I can start from.there

Until you present your architectural drawing and the nature of land (topography) any figure you get might not be helpful

In our current build, because of the nature of the land (topography) we are using twice the number of the expected blocks for the design on a level ground.

Structurally, there are two types of buildings
1) Buildings supported on load bearing walls and
2) Buildings supported on frames, otherwise called Framed buildings

Framed building as the name implies, is just like a frame which consist of slab carried on beam which is in turn supported by the columns.

The frame (slab, beams, columns, staircase and foundation) must be completed and left for 28 days prior to the erection of any block wall.

Framed building is arguably the best method of building construction , however the limitation why it seems people dont adopt that method of building in residential project is

Geometry symmetry
Frame structure thrive in commercial buildings such as complex, office buildings, malls etc because of the geometry symmetry of the beams and columns, unlike residential buildings where more often than not the columns and beams are not in symmetry and terminates at different levels.

Often time, we are asked the question how deep should a foundation for a storey building go? The nature / topography of a given plot plays a role as to how deep a foundation should go.

On this particular project, our workers are already mounting temporary scaffold to enable them continue work.

Another advantage of doing a high foundation is that it helps rain water to run off naturally and prevent pooling.
