Your so ignorant. I don't even know where to start from. But seek wise consent next time

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

I encourage no one trip waste their money on such nonsense.

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

I expected much more vehement defense than this.

You’re just a pained asshat.

It’s also “You’re and not Your”. You’re not only ignorant but half educated too

Sometimes this calculations don't work because of where the bricklayer will need to break the block into two and the second side will not be useful most times blocks break unexpected

I know you didn't read to the end

Make I Learn.

You make additional block's calculation for unforseen and miscellaneous, in case you have broken blocks during laying. Op has calculated blocks without unbroken.

YAWNS

Xtopher123:
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..

Yeah... I'm a builder tho..
I can effectively work as a builder, cost engineer,design as an architect and a structural engineer, give consultancy advice too.

Dangote... pele o

This is not my job, my job is to provide the money required. Everybody should eat, if one cheats you, shame on him.

After calculating can the building stand without money we need how to make money first.

Good job.

Obinoscopy:
Wow this is interesting. Thanks OP.

For the likes of those that don't like Maths, I guess they've seen an additional reason why they need to like the subject

Lolz.

I don't quite agree with you here. I believe in learning all you can as you progress in life. Does it mean because you are not the one building by yourself, you should not know what is going on?

The Op did a very good job. Simply commend him for it. At least he has opened the eyes of those who have been quietly asking themselves this question.

Op please could you explain how to calculate amount of materials, sand, granite and all, needed for a particular amount of concrete?

Is it only blocks that you need? even with this your style you are still not accurate ,no provision for mortal t.

Thanks for the info.

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

Are you referring to actual quantity surveyors and estate valuers or you mean quacks parading as professionals?

One of the most useful Nairaland articles ever.

There should be a "Most interesting article" award here and readers can nominate.

I know Explorers would win many ...but I would nominate such an article.

Kudos. ..I barely read the fine details..just skimmed through. Figures and data make my head ache

Correct

An inteligent response.

So, here's what I wrote.

Quack or no Quack (no one should hire a Quack in the first place). Small self-builds, like what the OP posted, doesn't need a QS to be involved. Nothing anyone can say will ever change that opinion of mine. QS on here have tried before and I will always defend my opinion.

I am currently building a 4,000 and 2,000 square feet structures on my site, no QS are involved. Why should I need a QS to tell me how many blocks I need? Am I not going to buy the number of blocks regardless? Why not apply the QS fees towards block buying?

I also am starting a professional custom home building company that will build small gated estates for sale. For that, I will need a QS because I need to provide potential investors, both bank and private market, with data.

I hope that you can see the difference.

To recommend in a blanket manner that ALL builds require a QS is ludicrous.

Nighouseplans:
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

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, 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!

But you are on point.


Why engage a QS for this project. It makes no economic sense at all.

Lol @ the first paragraph, what sort of QS will even want to be awarded that job? Na so life hard am reach.

You are very correct, it is almost like common sense.
