How many bags of cement and sand can this building take pls.

Oya send your Address.

churchee:



Almajiri Musa, come over to Enugu let me train you.

Nice.

SafetyFirst:


No Sir. I'm a Civil Engineer.

Respect!

area and perimeter application in math.

InvertedHammer:
Good information.

Verily...there is something about mm that irritates me.

I find inches more appropriate.

/

yes. inches ok but mm/mtr is SI Unit.
world standard method of measurement.
still use ur inches but get familiar as there are places you can't work if you don't know measurements in meters.
mm, cm, mtr, km. OR
inches, feets, miles.
it's easier to grade in mtrs that to grade with the old way if you can learn it, you will love it.

Give your Project to a quantity surveyor and don't bother about all these..

What about Frame buildings? Do you also do the calculation yourself?..

Nigerians we like cutting corners..

Its jst for sake of knowledge and to test the integrity of ur architect/ or site manage, atleast u wnt be a mumu

ncoolsome:
Op we should always let d professionals do their job before on contractor wld say "u sabi calculate abi" then end up using one bag of cement to mix 100 bags of sand..

if a workman decides to waste ur materials/money because you know, then prosperity is far from such workman. I will remain poor for a long time.
it is good what you doing is open to all and that's why the white do better than us in most area of life.

Also calculate the total number of cement, sand, iron to be used.. Yeye dey smell

Please, I have a small land measuring 23 by 50, is it possible to build two bedrooms on it?

What is the number of blocks required to complete this building?This is a common question asked by prospective home owners especially after the building design phase.It is advised you use trusted professionals for your building project. This saves you time and money. However, if you are taking charge of material procurement or just wish to confirm number of blocks required for your project, these 2 simple steps outline the process outlines the steps you need to take. A simple 1 bedroom apartment is used in this case for clarity.

These are the two basic steps: Step 1: Calculate wall areas. Step 2: Divide total wall area by area of one block.

Step 1:

To calculate wall areas, we will calculate the total length of walls and multiply by wall height(see plan image below).

Area=Length x Breadth, In this case since we are dealing with height,

Area=Length x Height

Calculate Length: Looking at figure 1 below,we take length of vertical walls first(from left to right), then horizontal walls(from top to bottom)

Wall 1= 8000mm , Wall2=7755mm, Wall 3=3675mm, Wall 4=4100mm, Wall 5=3900mm, Wall 6=7950mm

Wall 7=3525mm, Wall 8=5975mm, Wall 9=5600mm, Wall 10=4425mm, Wall 11=4200mm
Sum of all wall length is=59,105mm.

Use height of wall at 3000mm.

Rough wall area (Wall area including openings) =59105mmx3000mm= 177,315,000mm

Remember we have some wall openings at the entrance, doors and windows. We have to subtract areas for these to get the actual wall area:

We have 6 doors with measuring 900mmx2100mm: 6x900mmx2100mm= 11,340,000mm*2

We have 8 windows measuring 1200mmx1200mm: 8x1200mmx1200mm= 11,520,000mm2

We have 1 window measuring 600mmx600mm: 1x600mmx600mm= 360,000mm2

We have 1 opening measuring 3300mmx2100mm: 1x3300mmx2100mm= 6,930,000mm2

Add up all opening areas:

Opening area: (11,340,000+11,520,000+360,000+6,930,000) mm2= 30,150,000mm2

Subtract opening area from the rough wall area:

Actual ground floor wall area: (177,315,000-30,150,000) mm2= 147,165,000mm2

Area of foundation walls:

Also,remember we have a foundation. The foundation area depends on the number of courses laid. For this building, we use four courses of block wall as foundation (Strip foundation). This is roughly 900mm high.

We simply multiply the perimeter of walls we got in step 1 by the height of the foundation wall. Area is still length x height. But now the height is 900mm.

Area of foundation wall: 59105mmx900mm=53,194,500mm2

Total wall area = Ground floor wall area+Foundation wall area

=147,165,000mm2+53,194,500 mm2= 200,359,500 mm2



Step 2:

Area of one block is 225mmx450mm= 101,250mm2

Number of blocks is total wall area divided by area of one block:

Hence, number of blocks is:200,359,500/101,250= 1978.86 blocks

That’s approximately1,980 blocks. You may want to add a certain percentage for breakages and off-cuts. If you use good quality vibrated blocks you only need to add a little.

Wish you success on your building project.Thank You!

Interesting!!!

Guys, abeg I dey look for civil engineering job ooo. I love my profession die

Is the quantity surveyor going to do a different calculation than this our problem in this country is that we are too lazy to get involve with things as important hence we contracts them,allow people cheat on our intelligence or later start crying foul play or complaining that the work was not properly done.

Bro unless you wanna buy up a house, get involved in every calculations,even if they wil cheat you but it wil save you some coins that may runs into millions#myopinionsir#

your Project to a quantity surveyor and don't bother about all these..

What about Frame buildings? Do you also do the calculation yourself?..

Quantity Surveyor is the most useless profession in small self builds.

I encourage no one waste their money on such nonsense.

The cost to hire a quantity surveyor can be used towards the project.

PS: I’ll be waiting for the associate members of Nairaland QS to respond with their typical hunger induced vitriol

Very true narrative, in trying periods of economic downturn I should expect professionals to be compassionate with their pricing and see how they can assist clients to achieve their home building goals rather we see some of the acting like Hawks waiting to snatch the chicks from the mother hen

Appreciate your input to this discourse sir, one bottle of origin and cow tail pepper soup to cool down deflect the supposed attack from the NL QS.

Thanks bro. I just finished my block work. na plastering levels now. God help us to complete it

yes. inches ok but mm/mtr is SI Unit.
world standard method of measurement.
still use ur inches but get familiar as there are places you can't work if you don't know measurements in meters.
mm, cm, mtr, km. OR
inches, feets, miles.
it's easier to grade in mtrs that to grade with the old way if you can learn it, you will love it.

Not looking for work.
I usually convert back to inches.
They are all units of measurement of length.
You say 254mm. I say 10 inches. Both lengths are the same.
Everyone is happy.
I am beefing SI unit. I think mm creates a lot of room for errors. If it is cm, I will understand.

Good to this op

My friend, wee u keep kwayet?

Nice one

Your calculation is wrong. You forgot to subtract the area of the lintels. That is why it is safer to engage a quantity surveyor.

Nice info!

Still information is knowledge. One needs to know all these information so that one can also be aware when one is being ripped off

how many blocks can one have from a tipper of sand and how many bags of cement will it take.

No be lie!
The calculation assumed mortars don't occupy space at all!

Contact me, I am a Quantity Surveyor.

Very informative... Nice one op

saydfact:
On point OP.. To reduce figures, you can use meters where 8,400mm = 8.4m and 225mm =. 225m

When i clicked to open this thread on FP, i initially thought it was ur thread ( https://www.nairaland.com/4191428/how-calculate-how-many-blocks ) that had finally landed in the promised land, but alas!!!

Keep up the good work sir, we are following bumper to bumper. Your threads are indeed very helpful and informative.
