Don't omit column at the corners my oga. It will do your building a lot of good

This is fantastically Ok, Please can i have the comprehensive cost for roofing to include the number of hardwood used, the square meter of the roofing sheet and the workmanship.

Nice job bro

Ok sir... We are developing a building model that will pay more emphasis on the strength of the building.
What we have been able to do was to introduce ten column per flat to make the house more rigid. this is necessary when you look at the strength of the block we generally use in our building construction.

Thee columns were spaced with minimum distance of 3.6m to help carry the intended concrete facial ( parapet ) and roofing load.
The columns were also reinforced with minimum diameter of steel to reduce cost.

From cost perspective, its not out of place to reinforced the building with about N 76,000 in other to avoid any structural failure in the future, considering the fact much more will be spend on the finishing phase.

Here is a simple breakdown of the column:
1.footing with size of 600mm x 600mm only need 8nr of 600mm bar
total number of footings = 20
nr of bar required = 20 x 8 x 0.6/12 = 8 bars
cost of Y12 @ N1,100 = N8,800

columns of 3.75m high
20 nr of column with four bars per column
number of bar required = 20 x 4 x 4/12 =27bars
cost of bar = N1,100 x 27 = N29,700

Links of 750mm length spaced @ 400mm center to center
Number required = 3/0.4 x 20 x 0.75/12 = 10Y10 bars
Y bar is N900/br = N9,000

Binding wire = N2,000

Total amount on materials = N48,500

Workmanship = N25,000

Transport = N 2,500

Total =N75,500

sir, you didn't put into consideration the length of the bars when calculating for the number of bars required. Pls how did you come about your own calculation?

My Oga,

Am still expecting the comprehensive cost of roofing as you promised.

wow.... The work is moving..... We are patiently waiting to give it an exquisite design and touch of quality....

Look closely..... You will see bar length.
Check out for '12'

You mean length of a single bar in a column is 12m?Please I am trying to learn, kindly expatiate better sir.....

Check out for 4 x 4/12.... The first 4 means 4 nr of bars , the second the second 4 means 4 which is the length of the bar

Please can you give us the cost update?

this is nice.
the plastering is quite dark.
what is the mix ratio?
do u know how many tons of sand makes one wheel barrow?

can one make use of columns without roof beam?
that is, can i terminate the columns at the lintel level?
thanks.

1:1:4 one part of cement to one part sharp sand to four part of plaster sand.

One wheel barrow is equivalent to 4 head pan and one head pan have a weight of about 25kg , remember one tonne is equivalent to 1000kg.
