Although I see you used the word affordable but I'm wondering why the window are so small for a security box. Are you aiming to use CCTV to see the compound and not line of sight?

Just out of curiosity. As a structure of course it's beautiful as is all your work.

Thanks you sir. The Windows are big enough for the security house.
Main house Windows are 750mm x 1500mm.
Toilet window = 600mm x 1500mm.

The main room have two windows for cross ventilation and Windows need to be in alignment to the main house with Windows which are 750mm x 1500mm

I want to share this small security house with my oga here..
The challenge was to build a small security house that is decked and still have something befitting for entrance of house.
I want something beautiful and affordable at theaame time, so I came up with this.

when i read that you can see the diff btw Anambra and niger/ondo, i gave up on your lies. Anambra remains far wealthier state apart from our common wealth, lagos state: home for all.

So, Lagos is now your common wealth? if that will make you sleep better, I will to agree with you.

What do you mean when you talk about wealth?
Are you talking about good road network, portable water supply, good town planning etc.

Do you mean anambra have good mass transit, railway network, sky scrapper, good grean areas, portable mass housing for working class?

Awka is a developing city like akure or Minna, they all need basic amenities to compete among good cities all over the world.

I am a yoruba and I don't consider Lagos to be a thing to be proud of. We will build a better Lagos where everything works.

I am presently in Ogidi close to akpom village.
There are big building there, in fact I am working on one but apart from that I can see no difference in road, pipe born water, sewage system etc.

I am a native of ondo but from suleja in Niger state. Suleja is a better town than many South eastern town I have visited

Chinom:
There are also dirt poor people in USA and Europe. So what's your point. Every Igbo man cannot be rich. Why don't you carry out a research and come up with the statistics. There is no doubt the Igbos have the lowest poverty rate and even distribution of wealth in Nigeria. You do not have to go to Igbo land to do your research. Take Lagos for case study. Or even Kano before the Boko boys came.

I disagree with you my friend. Igbos don't gave the largest number of middle income earners because in Nigeria middle income is a myth, you either poor or rich.

wiseoneking:
from yoruba land to hausa north, they will always appoint igbos but the last state in igbo land to do so will be Anambra. They seems to have that superiority complex above all black men. They neither fear god nor man. Their greatest treasures are in their human resources. Ask Tinubu, Fashola or Ambode, they will tell you that they can do without Anambrarians. Yes, richest man by forbes is Dangote and 2nd is a yoruba man, but those two tribes have more poorer population, dwindling litercy, high poverty rate than the igbos. While there is average wealth distribution among the Igbos with far more middle class than any tribe in the country. Igbo land is not where you have one king like Otedola or Dangote dominating their tribes. What is one thing you have gain from this people, see, you are still unemployed. Lol

People make a lot of generalization without visiting any part of the country proper.

How do you know that igbos have the highest middle income class in Nigeria?
How do you know that igbos have the highest literacy group in Nigeria.
How do you know they have the lowest poverty and even distribution of wealth?
Without any statistics to back your assertion, you are just another tribal bigot.

Igbos are quite hardworking and very industrious, same can be said about yorubas and hausas.
Igbo dominate retail industry in Nigeria, yorubas dominate artisantry, technical work ( hand work).

I have been to a quiet number States in Nigeria and I can see poor people e be everywhere, bad roads, lack of proper sanitation, epileptic electric supply, illiteracy etc. I am presently in anambra and I can see anything different from say ondo or niger state

Mayor78:
Please how many iron rods on average would you expect to complete the decking of a 5 Bedroom duplex with floor slab measuring 16.684 x 15.924 meters. Am trying to work that out going by the 'Floor Slab details' in the Structural Drawings by calculating some of the figures on the drawing. E.g where it says 31-Y1217-200 c/c B; 21-Y1018-150 c/c T, I want to believe that it is talking about 31 pieces of Y12 on base and 21 pieces of Y10 on top.

How do I interpret the numbers above, and what are the the methods to calculate the number of rods required per given space

(Guys don't laugh too much on my ignorance here!). Look Abdul am trying to learn fast here, time is against me so need your help asap. LOL!

Without the slab detailed drawing and with the limited information of
Area of slab minus opening 16.684m x 15.924m
Spacing of bar and bar specifications
Y12-200c/c B ( I will assume this is for BB an TT
Y10 - 150 c/c T ( I will assume this to be for both 'BT'
'TB').

Bottom bar required :
Main = 15.94 /200 +1 = 81bars
length of bars = 16.684/12 = 1 and half each length
Total number of bottom bar required conservatively = 81x 1.5 Y12 spaced @ 200mm c/c = 122 length of Y12 required.

For distribution bars
16.684m/150mm = 112
Lengh of each bar is 1 and half
Number required = 112x1.5 = 168length of Y10 @ 150mm c/c.

Note, I didn't calculate the top bar because I don't have the slab layout.
I assume that most of shorter span is across the 16.684m span.

Very good question sir. I may not be as to give you an exact figure without the slab detail plan but I will try to come up wit an acceptable number from the floor Dimensions and a simple detail that you posted here.

31-Y1217-200 c/c B : means 31 number of high yield bar of 12mm diameter with a mark number of 17 spaced at 200mm center to center (c/c) and positioned at the bottom (B).

21-Y1018-150c/c T : means 21 number of high yield bar of 10mm in diameter of Mark number of 18 and spaced at 150mm Centre to center positioned at the top (T)

Note for slab, the designer gave to be more specific with the position if the bar. We have two ways of been more specific, either using BB (bottom bottom), BT ( bottom top) or T T (top top), TX (top bottom).
The second way is by using T1, T2 and B1, B2.

BB/B1 : means the bar is place at the bottom side of the bottom bar, these are the main bar of span reinforcement in a slab and their effective depth = depth - cover- half of its own diamter

BT /B2 : thee are the distribution bar of the main bar for span reinforcement, they are placed immediately on top of the BB bar and their effective depth = depth - cove - diameter of BB - half of its own diameter

TT/T1 : these are the main reinforcement of the support of continuous end of a slab or for a cantilever end. They are placed at the top most of the slab to control bending there.

TB/T2. these are the distribution bar of the top reinforcement in a continuous end of slab or for a cantilever slab. The are placed below the TT at the top of the slab

It seems there is wide variations on the number of this block moulding thing. Can other experts please shed more lights, Abdulwastecx if you still dey please!

We started doing 6" per bag. They started with 40 per bag but I told them following information to increase it to 45-48 per bag and the guys said that I would increase their money from N700 to N800 per bag if they have to increase the quantity per bag, I want to believe that they prefer to do less in other to maximise their bag count and as such tell you that you risk loosing blocks during packing as such number will not be solid enough.

Somebody need to help us here as I wouldn't want to increase the load on the house simply because the artisans wants to maximise their outputs. I would prefer to achieve quality with less if it is possible. That's the overall aim anyway. Somebody help please!!

Good question sir. Hand mould block lacks proper compaction and I believe 45 per bag for 6'' hollow block is OK.

The mix should be purely very sharp and and cement in areas where stone dust is very expensive, in Abuja and it's environs where stone dust is as cheap as sand, stone dust is preferable.

Some people make a costly mistake of mixing plaster sand with sharp sand For block moulding in other to save cost of cement but the truth is plaster or any silt reduce the strength of block.

I think you should also increase their money

donvicky2007:
make sure ur source all the woods you will be using in your local (Village) market,it is more cheaper to mould blocks than to buy from block industries, do you have any river in your village were you can buy sands cox its more cheaper than going all the way to River Niger to buy sand which is expensive including cost of transportation, Cement is N1400 here in Onitsha i dont know the cost in your village, do u have well were the labourers can draw water cox it will be economical than buying water. Cost of labourers runs from N1500-2000 for a day job here in my area so it will be more cheaper in your village. Go with the local stone instead of buying gravel.But do u have the bargaining power so as to bargain with ur Contractor for his workmanship.make sure u get for yourself a good Engr or contractor to handle ur house. But know that a good roofing will cost you upto 500K and above both the woods and roofing sheets,so bargain with ur contractor on how to manage that for you.
But if you make a good Quantity survey of the materials to be used that will the best cox it will let you know how far your budget can go.

Use local stone for a 6 bedroom duplex?? Oga abeg no advice am to build house wey go fall.

6 million naira can only do the following
1. Foundation : depending on nature of soil, budget about 2.5m up to dpc level.

2. Ground floor block know work and ring lintel : about 5000 blocks, five trips of sand, 100bags of cement, 100 Y12, gravel etc wil cost up to 1.5m

3. Suspended decking (slab work) will cost you up to 3m.

At this stage you will a deficit of 500k

I have wondered why most are not embracing polystyrene as an alternative material for parapets, window and door dressing, decking etc. I am planning a project and would like to identify where and how to efficiently and effectively use polystyrene.
How does the total cost of the fascia compare to concrete parapet? Also, how can I contact you to discuss possible involvement in my project.

You can contact me through my mobile number 08169492682 sir

That will be great sir.

Polystyrene fascia is cheaper than insitu cast concrete fascia (paraper) by almost 30% to 40%.
It is faster to install and construction is neater.
Light advantage is another major importance.

As for other structural use, like polystyrene rib in ribbed slab construction, it is a good thing to use for suspended floor in residential houses, hotel, school etc. It is cheaper than concrete slab and also faster. It also contribute much less load to other structural members like beam and colum

You want to "dash" somebody COREN Certification ...for Free?

Even if you are the Registrar of COREN, you still cant dot that!
But you are not in anyway! And it would be criminal too!!

Seriously, you seem to be alluding that such Professional certifications mean nothing, right.
You cant be more wrong.

Like my Architect (Chartered) will tell you, "Oga, its that Stamp and Seal you are paying for, the drawing itself is not costly and can be done fairly, by any Architect"!
Same goes for a Chartered accountant, software Engineer and any profession where "professionalism" is valued and required.

It reminds me of those illiterates who will say: "Dont mind all these Graduates, there is nothing they can do that we cannot do"!

Just making an "analogy" to emphasise how "those who dont have it, always try to thrash it",.... l know say you be Ogbonge Graduate o! So, dont throw bottle at my head!

I think he is joking with that comment and I don't know why you are very angry with your comment.

I will get certified soon and that will be no big deal to me, I may not even use the title in my name.

The seal and stamp don't make the drawing, that is the mistake we always make. The proper use of mathematical principle and your engineering judgement make it.

mavverick:
Thank you for answering my question.
Let me ask, are you a registered COREN engineer ? Do you do structural design work and produce the drawings such that a builder and I myself can understand, as I had to learn how to read plans when it got to one stage.

Would you also require a site visit before you do your structural design ?
Should Architect also be the one/with his cronies etc to do the mechanical design and also the electrical one ? Reason I ask is coz i remember this causing delays and my architect said that he was waiting on the electrical people to finish the electrical design ? Same with mechanical, but some aspects of it were changed during the course of construction.

I am not a registered engineer yet.
I do structural design work and produce the drawing in accordance to standard method of detailing structural concrete, in which all the calculations are detailed drawing are check by registered engineer.

Electrical and plumbing (mechanical design) will depend on the complexity of the building.

Site visitation ( Geotechnical analysis) and engineering survey will be a necessary thing to do before commencing the project.
The soil test should be carried out by an independent film and the result should be presented to the structural designer to design and proposed a reasonable foundation type and specifications of the structural members. The survey we enable him to know how to control flooding and nothing horizontal and vertical alignment of the structure.

But we have to know that in design, two type of structural members suffices namely, sub structure ( all members below the building ground level which depends on engineering properties of the soil) and super structure, those above building ground level ( these are independent of the soil properties.

These super structural members ( suspended roof/ floor slabs, beam, column, reinforced wall etc are further divide into depend and independent structures.
Slab is an independent structural members because it only depends on its self weight and weight of occupancy (imposed or life load), wind load ( high rise building where it is a flat slab).
Beams depend on its self weight and weight from slab.
Column depend on its self weight and weight from beam ( beam and slab) and flat slab alone.
These other members are dependent structures.

brabus:
Who are you sef? Must you make sense all the time. You also top with up with mathematical calculations. You are the only engineer who proves his worth here unlike me. I expect those engineering jargon and mathematical calculations to be thrown in at all times by seasoned engineers and you never failed to disappoint me.

God bless you real good.

Thank you my oga.. But I am not an engineer yet, don't let COREN come after me lol. We are getting there sha. Thanks sir.

texazzpete:
I didn't 'insult' you. It was a silly comment you made, and i stated that accordingly.



Nobody is buying a standalone house for N25m. Did the part i mentioned about 'land density' fly out through your ear? The land for these type of estates are acquired as a bulk purchase, and because of the terrace or apartment design, several housing units are fitted on one plot of land, drastically driving down the unit cost of land per house. When the economics are run, there's perfectly enough cash to build a safe, secure house. It all depends on the business model. If the developer's plan is to minimize profit on the house to maximize returns from estate management, service charge fees etc, where's your analysis to say this is not a viable business model?

Your problem is that you speak out of ignorance. There are MANY business areas where these models are used, and they work pretty well. Sony sells the Playstation 4 at cost (or even a small loss) at $299, but they make billions in profit from sales of games, licencing fees and yearly subscription for online play.

Using your 'China' example, take a look at Xiaomi. They sell a phone with pretty much the exact same specs as the $700 Galaxy S7 for $400. While Samsung makes profit from the hardware sales, Xiaomi's business model is to sell their phones at razor thin margins yet make hundreds of millions in profits from sales in the preloaded Xiaomi appstore. This has paid off since they are now one of the top 7 phone manufacturers in the world.

Your darling estate developers that sell houses at a premium are using the 'Samsung' approach. They sell FEWER units with a higher per unit profit. Lekki Gardens should nominally be on the 'Xiaomi' approach. Selling a crazy boatload of houses at small profit margins, but much higher returns from service charges.

Then you - with your limited understanding - pop up to claim that the MAJOR culprits in an apartment block collapse that killed 25 people are the folks who paid money for these flats. And you consider it an insult when you're rightfully challenged over the inanity of this claim.


And to clarify, the N25m for a terrace duplex is only in places like Ajah where land prices are MUCH cheaper than in the area where the building collapsed.

Wholesome analysis sir. It is clear that the customer ( home owner) have zero blame, since they pay for a service that was rendered by a supposed competent film. The blame should be on the developer.

It make business sense as clearly illustrated by you, and to think of it this way, less than 10 % of Nigeria population can even come up with a 25% for a dwelling accommodation.

It is sad that people who invest their hard earned money lost their investment to a dubious organization
