Actually d prices he gave you for each material are fair to me. But not sorry to say this. Your building will be of low quality

First of all d guy is planning to use just 2000 blocks for the foundation of 2flats ( since its 2 down 2 up) if my calculations are right it means he will only be digging into the ground by just one or one and half feet. Dats bad. People do it. But its bad construction and also u should try to be atleast 2feet off ur natural ground level ( cos of other works). Dat numbers of block can't get u dat level.

2. He has plans to set 100 blocks with a bag of cement. Pls don't allow him to do dat. Don't be penny wise and pounds foolish.


3. I recomend a minimum of 16mm bars for column (pillar) reinforcements. Thr is a way to arrange 12mm bars dat it will be equal to d strength that 4 16mm bars will give u but seeing the guy is already planing to use 100 blocks to a bag of cement I am guessing he will also use just 4 12mm bars in the columns (pillars)

He is nice to you on d prices. Except 4 cement you can get dat 4 less

But you will be building a serious low quality and unsafe house

I dint even see d 6inch block b4. Ar u sure u called an Engineer?

The cement quantities seems to be inadequate, how is it possible to cast all the lintels (plus columns) with 15 bags? Also rods, @ wunmite, nice points.

Than you wunmite90 and spyder... I told him about the rod before tho I dont know much about building upstairs but I now for sure that rod was too small. I will have to contact a good builder for the project. thanks once again.

Waiting to secure all the approvals before we break the ground here, we have got our borehole working, our site store erected and workers waiting to start here.

Site store, done.
Borehole, done.

I was right to insist on pouring some soil into the site before the site store. The land is getting more water logged by the day. Still watching and taking notes.

Closer. ......

My brother, we don chop sallah ram finish o

I bought a new pumping machine for this land........

Because the ground is submerged. ........

pls how many blocks should be set with a bag of cement.

what is the ratio for sand to 3/8 to cement for foundation.

Thanks

I had to return to this site to do a site test to assure me of the type of soil characteristics we are going to be working on. To help me, a site test has been carried out for this land, but I am not taking any chances, I want my own independent testing. So I ordered a dig.

I got ground water at about 1.2 mts, we closed for the day, more observation to be carried out later.

well done boss, you can contact us for your Aluminium works @ Perfect Touch Aluminium . Tel:08153665659,08067079715. Thanks

well a standard motar mix is ratio 1 : 5 ( 1 headpan of cement to 5 headpan of sand). but over here in our country we go as high as 1 : 8

also for 9 inches block one bag of cement is naturally expected to set 30 blocks. but we also see people setting as high as 50 blocks with a bag.

i dont fully understand your last question. you can please rephrase it to help me understand.

1 bag of cement to 70 blocks is ok

Plz at ur PH sites in the past where and whom do you get quality granite from? and howmuch do you consider as a fair price for a 30 tone load??

doncaster:
1 bag of cement to 70 blocks is ok

I will only agree to that if its 6 inch blocks.

are you using a raft foundation?

Yes.

i will love to see your process because this is the first raft am watching you do, all the best.

let me rephrase pls

how many 6 inches blocks should be set with a bag of cement.

what is the ratio for "sharp sand" to "3/8 Sand" to "Cement" used for blinding the foundation for a fence.

Thanks again

U can set as much as 70 6inches blocks( but I prefer less) with a bag of cement.

Blinding is actually different from actual footing, but not to pretend I don't understand what you are refering to cos most of my own workmen self actually call it blinding.

So for fence we don't usually bother ourselves with engineering standard practice because its not expected to carry extra load. D major factors that determine our footing is actually the soil type.

I will say use 1:3:6 and make it 2 to 4 inches thick. Dat is for every head pan of cement put 3 headpan of sand and 6 headpan of granite. But if ur ground water level is high things might have to change.

Assuming 60 by 120 feet land and 4 inch thick footing you will be needing. 21 bags of cement , 5 tons of sand (u need less but dats d smallest truck available u just add the remaining to that which you need to set the blocks) and 5 tons of granite.

For setting assuming u want to set 3000 blocks as fence just buy additional 10 tons of sand and 45 bags of cement.

I just gave out all d information cos I don't know d intended use.
