Tobbyboy2011, Seek more quotes from 2 more people and compare them. I did something similar last year, I made my own blocks. Mould your own blocks if you can; it's gonna be stronger and cheaper.

Below is the quotation my builder gave me. Please builders in the house help me look into it and advice

Block=4000(amount 800,000)
Sharp sand =90tonnes (amount 189,000)
Soft sand =30tonnes (amount 63,000)
Granite =60tonnes(amount160,000)
Cement =120bags (amount 312,000)
iron rod=100length (amount 190,000)
Gutter rod 30length (amount 51,000)
Larteraite 60tonnes (amount 90,000)
Binding wire (amount 5,000)
Total =1,860,00
Plus (+) workmanship =300,000
Ground TOTAL=2,160,000

Builders in the house please help me, location is ibadan, and its a 6 Flats Of Two Bedroom Flats A Storey Building

This is an example of an incomplete and unclear quote. There are so many other inputs needed to build a foundation which I couldn't find in this list,

1. I couldn't find any wood in the list, or nails.

2. There is no mention of pegs and materials for setting out the foundation.

3. Cement quantity is so small for a double wing of flats, if he is planning pad footings, blinding and columns plus DPC.

4. Iron rods are not clearly marked out in the right sizes, you will need at least 3 sizes of rods for the building you are describing.

5. Block quantity seems too much to me for a double flat, even with a high foundation you cannot go above 3,000 blocks for foundation only.

6. There is no way in this world anyone can handle the workmanship of such foundation with only N300k, excavations, column bases, concreting, iron fittings, column placement, carpentry, bricklaying, sand filling and soil compaction costs should surpass that?

7. No supervision charges for the man who controls the site?

8. Transportation, loading and offloading?

I think all these should be spelt out to avoid conflict when the work starts. Thanks.

100k for the POP is too expensive for 15m². For materials, it shouldn't take more than 7 bags of white cement and 5kg of sponge. Get them to tell you how much they would take per m², which usually is 1k while you purchase the materials. Alternatively, 3k per m² seems fair for both materials and labour. I have just finished almost 200m² of pop
twinskenny

have not been able to post for a while, guess spambot or network...thnks to all for the suggestions
yeah, i made an error. its actually 60sq meter.

also considering screeding the walls, someone said its 350naira per sq meter..then you buy materials. who has an idea of cost of materials?
learnt its paint and pop

Thanks Spyder

The location is in IB and a developing area

I bought nails even before I gave him the contract, I have borehole there and they sell woods blocks and cement around the area. He also said during the process we will dig soakaway and use the sand for filling and the remaining blocks for the soakaway, he is like a family friend and he said i should pay him once he's done because he has been begging me to give him a work for the past 5 years so this is our first time working together. I will upload pictures too he said foundation digging cost 70k and he is using 3 to 6 courses for the foundation because of the land condition.

Is this your project a bungalow or storey building?
If it is a storey building, i hope he left spaces for reinforcement for pillars?
I prefer this block laying method before reinforcement though....More easier to construct...

WOW!!! What a lengthy read. Spent hours reading up on all the posts i missed. It was well worth it though. Always a pleasure, enlightening and informative reading up posts on this thread.

It is surely one of the very few threads on NL i find intellectually beneficial. Keep it up gentlemen and ladies. More grease to our elbows.

A very warm heartfelt appreciation to all the contributors on here- professionals, building project owners, and every other person who offers constructive criticism on this thread. A special shout-out to Hajji M for this wonderful initiative (opening such a thread to accommodate all and sundry). God bless us all!!!

OK.

But like Rubbiish stated up there, column spaces are supposed to have been clearly dug out, base deepened, basket placed after blinding then column starter bars placed on baskets before block laying. I couldn't see any starter bars protruding from the column positions? I am working on the assumption that this is a 6 Flats house, 2 story building. Please contact someone else with a better experience to check if this is the correct process as spelt out in the building plans.

Money is too hard to make these days, not to talk of breaking up and repeating jobs when a mistake has been made.

I was expecting something like this https://www.nairaland.com/3787606/new-8-flats-3-bedrooms

Quite true
Just that my storey buildings was constructed using the block before column approach, but is was only after just one coarse. My worry with the op build is the high dpc, baskets & starter bars should have been planted before it got to such height.

This is the best practice whether 1 flat or 10 flats

Looking at oga syder's thread, even as a lay man, it's apparent there was no concrete encased metal beam at the base for the support columns to stand on for solid base.
I would suggest you put the work on hold and get the free advice of professionals here before proceeding.
You may want to use the thread used as reference as a guide also.

Please correct this error before proceeding, if you go beyond this level it will be hard for you to place the reinforcements, get a professional, don't gamble with your building.

Your uploaded pictures barely shows any starter pillars at any of the free spaces which might also mean there is no column base (basket) except you're trying to say they have poured concrete over it which is hard to believe because that is not the ideal practice for your type of structure.
Get a real professional or take time to go through this thread. Everything you ought to do is somewhere here.

Are you actually building a bungalow or a storey building (building with a suspended floor/slab)?
If it is a bungalow, you can get away with this type of construction without pad footings/basket reinforcement as the case may be but for sorey building that is a Framed structure you will need to make provision for the basket/pad footings reinforcement with a foundation columns/starter bar bend into the basket and tied accordingly.

For best practice, You will also need an engineer to specify the number of these footings, its dimension, the depth at which the pad should be founded below the ground level, the thickness of the footings, the diameter of reinforcements, number and spacing of these reinforcements. But if you are planning to build a storey building with load-bearing walls you may not need to have the basket/pad footings or columns but the foundation has to be designed as a strip footings that will carry the wall load and the block have the minimum strength required to carry th slab and upper floor load.

@bold is it possible to build a storey building without columns?
Re: General Topic Thread-To Discuss Anything And Everything in Building Construction by abdulwastecx(m): 3:47pm On Jan 27, 2018
Rubbiish:

@bold is it possible to build a storey building without columns?

Yes, it is. You will need to build with very solid blocks and if you are using hollow blocks you will need to place rebar at a certain spacing within the hollows and also filled up with weak concrete to give the block the strength required to a carry a suspended slab. This method is only limited to one-story building ( building with only one suspended floors) but for safety and due to lack of proper information about building materials strength it is always advisable to build any suspended floor as a frame
