Typical above everyone attitude that led you to change your moniker several times to hide face after embarassing yourself that many times.

You cannot push me to give you the code, you can only ask politely and i will get it for you.

I only respect you because from your history you should be as old as my father. I guess we Nigerians have respect for elders by default, that makes you above me. Happy

Hello nairalanders, Architects, Builders and Civil Engineers alike, how una dey?

There’s this little problem I hope we can all solve together. The plan attached is a 3beedroom Bungalow my client bought from one of these estate developers here in Abuja. I believe we are all familiar with their clause of having to build in accordance with specified prototype mandated by the developer. My client is a single young man and he feels a 3bedroom apartment is just too much for him for now. We consulted the developer and they relaxed the clause just a bit: we are allowed to alter the interior parts of the proposed plan but shouldn’t shift a block of the exterior (window/door positions MUST remain the same).

NOW.

How best do you think we can alter this plan to get a functional 2bedroom and another 1bedroom apartment under the same roof working with the earlier mentioned restrictions?

Every input will be warmly appreciated.

Thanks.

Josh baba.. .. I am on it

Our engineers in the house. Any thoughts ?

mavverick:
Just a thought that I had the other day.
Within a building plan there should be structural calculations done by a qualified structural engineer. They will calculate the load etc and specify where and how many pillars a building should have. Of course this doesn't apply to brabus who doesn't use the services of a structural engineer or simply uses the structural drawing of building A for building B, then kneels in front of prayer stone to pray all should be well. We have seen him do this to a client at Iba and I'm sure there are many more.


Back to the question, how do competent builders decide on where extra pillars should be added or perhaps new ones introduced where necessary. I will share what I have heard, but thought it would be good to get other opinions.

4nobody4every1:
Hahahaha, kneel before a praying stone.Lol....if you like kneel before Kilimanjaro rock if you dont follow the A to Z of building, it is a disaster waiting to happen

abdulwastecx:


I will give you some detail breakdown soon oga but to begin with, you under utilized the kitchen space

abdulwastecx:


Hollow port is made from burnt brick and used to filled void in a ribbed slab. The dimensions of the hollow varies depending on the design parameters of the rib slab.

There are three type of pillars from the perspective of functionality
1. Structural pillars (columns) in frame structure
2 . structural pillars ( columns) in non frames structure
3. Aesthetic pillars (column)

I will be using columns instead of pillars.

A column is a structural member that load from beam to foundation or to column or another beams. It also carry moment from this beam or slab (for flat slab). The load mostly carries are idealized as point load. It carries different type of load such as axial load, uni axial and Biaxial load. The load is said to be axial if the load act at the centroid of columns, uni axial if it has one eccentricity, and Biaxial if it has two eccentricity.

To know the number of column required in a house, we have to know the functionality of the house.

Structural column carries load from suspended floors or roof. The quantity of the column is determined by architectural requirement and load intensity.

For practical purpose, most residential building have their column space at maximum of 6m center. The most economical way of spacing column is 4.5m c/c.

That is why it's important to do architectural design with equally spaced grid system.

Spacing of columns is done to reduce bending moment and over hang both side help in a way

mavverick:


Thanks for the explanation.
I once had a structural engineer who said he would suggest extra columns in some place because when he JUMPED UP AND HE SAID IF THERE IS VIBRATION THEN A COLUMN IS NEEDED IN THAT AREA.

When the Strucural engineer that did the building drawing was challanged, he said the person is just trying to take your money and trying to find work to do, whcih may not be needed.

It also got me thinking, if the person jumping up is a Yokozuna, there might be vibration, which has nothing to do with lack of columns, but due to his weight.
Is this thinking of jumping up FACT or FICTION ! or is there supposed to be some kind of machine similar to the one used by Building Material Testing to test concrete etc.

Coz na one Engineer for NL talk am !!

See the picture below, if 2 of them jump up, one is likely to cause vibration where the other guy might not cause any vibration !!

mavverick:
How far with your comments about the kitchen worktop ?
Based on your analysis on slab/vibration etc, what kind of thickness should be used for a kitchen worktop, its not going to be carrying heavy load, most people use MDF/HDF and that does the job most of the time.

brabus:


Baba you cannot have digested the 476 page document in 1 hour na.

Take your time. The document contains everything you need to know about Nigeria Building Codes.

abdulwastecx:


I will recommend you use 3'' ( 75mm).
Use stone dust as the only aggregates in a mix of 1:6
For the Formwork I will recommend you use particle board plywood and spread polythene on it to get a very smooth surface after removal of forms
Use 6mm mild steel bar spaced at 200mm center to center both directions

abdulwastecx:


Slab vibration for solid slab (slab with edge beams) different from flat slab is a problem associated with large span slab without intermediate beams.

Most of house are built with solid two-way or One - way slab, when the slab is one one way reinforcement is needed along only one strip but two ways reinforcement needed in two ways.

Vibration problem is a deflection problem and result from a very thin slab. Thin here is subjective, which means a slab 150mm thick and plan area of 6m x 5m may be two thin when the slab is use in a shop or a public place because of higher life load (2.5-3kN/m2) instead of 1.5kN/m2 for residential.

Vibration indicates thinnest of slab or lack of adequate beam for solid slab.

It is a wrong practice to introduce column in a solid slab without adequate beam to reduce the punching effect on slab.
It is also a wrong practice to introduce hidden beam within a slab because such beam effective depth Will not be adequate.

Solid slab vibrate when depth is not adequate in deflection, which indicate need for increase in depth or introduction of beams.

Beam deflection is the only indicator for addition of column.

Brabus, You Killed it...All the Links where a Hit back to back....Thanks @ Brabus

mavverick:


Thanks Bro for the advice.

Just a few things, I dont have stone dust on the ground, only sharp sand at the moment.
I also dont have 6mm rebars, can i use 12mm and increase thickness of concrete or perhaps mesh ? If mesh, which one ?
also about the ply, I only have 1 by 12 on ground to line the base of the form work, I can ask them to go buy ply though, since its a small quantity and once the formwork is removed, it can be used for the next one. Or do you think its better to buy some small marine board. Seems perfect for jobs like this, and that wouldn't need polythene right ?

Also, just to explain myself well, onnce the forms are removed, tiles will still go on it, so it doesnt have to be as smooth as a boiled egg, in fact the surface might need a little rubbing so that tiles will stick well.

sgtkole:
Okay,

Is it advise-able to use in building a 3 story building.

brabus:


Sir KolaShangOne, tell me you didn't see the inconsistencies in the quote.
I understand that part but you didn't see that I also queried wall trim and eave angle.

Cladding is normally 0.25m (no assumption/approximation) while eave angle and wall trim is 0.150 girth. How come they're (wall trim and eave angle) more than the cladding in the estimate?

What about the scary figures? .55 is normally N1,150 (figure coming from installer who go chop hin own o), how come we got N1,750?

I don't like doing this online but I think the contractor is more of an enemy than a friend to this client.

mavverick:


I read this comment from BRABUS / BOSUN SHOYOYE and I just laugh.

Talk of contractor who is the enemy of the client.

Those that stole from my site using a van to cart away items, the money they got from it will lead to thier downfall, they will not use the money well, God will continue to punish them wherever they may be, and continue to ensure that they do not progress in life, Those that wanted to collude with others to defraud me at the time, they will continue to LACK !

BRABUS, OYA SAY AMEN TO THE ABOVE !!
I BET YOU DARE NOT !!, NOW WE KNOW WHO CAN BE A CLIENTS ENEMY

back2sender:

Because is the gang leader of them. Him boy Johnny don show another client of His. Birds of the same clothings

abdulwastecx:


1. You can use very sharp sand and 12.5mm gravel then of mix ratio 1:3:6

2. Marine wood will be ideal if you can afford it

3. If you have 12mm bar, you can go-ahead and use it

4. The suffice need to be smooth not the top since you are going to tile the top.

5. I think 75mm will be ideal since if too thick will render it not attractive.

I will you you are sketch soon

@jummymine - I decided not to look at the figures in my last post but when I looked I realized the major reason why Jesus Wept.

To prevent what happened in 1875 (like my good friend DominionNG used to say) from happening again, throw away the estimate and get a new one from a friend. The contractor who prepared this a great enemy.

Since my years in building, I've never spent up to N1,000,000 using long span roofing on a single build and below are the buildings I've done with less than N1m material and labour inclusive.

I've not spent that amount roofing any building except The Semi Detached Duplex in Diamond Estate Sangotedo where we used Wichtech Roofing. Anyone who paid more (for Aluminium or stone-coated) should ask for a refund. And there's never a single complain!

Brabus,

do all these prices include price for Wood Noggins (Roof wooden frames) "purchase and installations", in each case?

Tnx.

Are you serious? what about those with king point of 5m. You need to share more light to your comment. Pls answer the question about the woods

There is nothing in that reply that indicates that Segcy has given or is about to give him a job!

Secondly, saying he can be reached on 080xxxx is no different from putting your phone Number on your CeeVee!
If you dont, how then will the prospective employer reach you?

There is this penchant for we Nigerians to think those looking for a job have no dignity left and must grovel on the floor, just because they want a job.

A prospective employer actually has a duty to call the "potential employee"..... or how else is the employer supposed to "convey intent" to even have/start an interview or look-over of the candidate? And its no big deal FYI.
