Assuming you are going for a concrete mix of 1:4:5, you will require 133bags of cement, 24 tonnes of sand and 40 tonnes of granite or any other durable coarse aggregate of your choice

Employ a quantity surveyor. Don't cut corners. A QS is a professional at dis. Thnk u.

Nope, no QS on my site.

QS are a waste on small building projects.

EgunMogaji:


Because I consider the services of a QS a waste on a small private build. No QS is forced to respond.

QS is a dying profession IMHO. Revit, autocad architecture and their competitors feature quantity takeoff.

saydfact:


Roughly 2500 per m3... The more, the more discount you remove.., practical only when u doing big works ie u can't use it for small task like columns etc.

Thanks a lot

Gbam!
Correct person...

mutaalim:
cement 170 bags
sharp sand 40 tonnes
granite 50 tonnes
workmanship 100k

Please are you a builder or a QS. We can't keep giving out free professional advise you are Killing the profession.

The fact is that real professional advice can't be gotten here. Take a look at the estimating he did and you will see that he made no allowance for shrinkage and waste for cement. You can't get good quotes here.

2. I don't think any QS would want to be called upon first this type of project. A good and experienced builder/bricklayer can easily give you a reasonable quote for this. No Professional wants to handle projects like this cause we all know where the REAL money is...

There is nothing like German floor my brother. It is called oversite concrete. Convert your imperial measurement to metric to make it easy. Oversite concrete only have thickness which u referred to as height. Remove d area of d void space from d total area and multiply by thickness to get d volume of your concrete. From there u can get quantities of materials depending on your mix ratio.

German Flirt is the language a layman understands bro. Even when talking to workmen on site, you need to use the term they understand and keep the correct one for academic and contract purposes...

It's elementary actually.

We get enough professional advice that we need on here and we'll continue to do so. Many of us building from diaspora are blessed with selfless professionals that guide us.

I didn't read anywhere on here where I request the services of a QS. To me, and I've said this many times before, a QS is a waste of a profession in general and especially on the types of builds that we discuss on here.

Well, I never said you won't get a professional advice, I said a REAL I.e a realistic and more accurate advice can't be gotten here.

If you can do us a favour, Give use actual quantities of materials used for the floor and let's compare with the estimated quantities. Though there is allowance for differences but in this case, it will be to much.

You said a QS is a waste of profession, I wouldn't want to talk more about this, but I guess you've never met successful Quantity surveyors. Thank God you said to you. You are entitled to your opinion.. .

Like I said earlier, QS are not meant to dwell on project like this, but on large projects such as high rise buildings, large housing estates infrastructural development and the likes. That is where our servicis are needed.

It baffles me when some are saying advice shouldn't be given. No QS would want to work on projects like this except a student...

It's not my job to educate you. I still don't understand why you continue to be bothered.

I also stand by my comment that QS is a waste of a profession.

Trust me, I've debated it with heavy hitter QS on here. You are arguing from a weak base and frankly you're a bore.

Yes I noticed. But it all should b left for professionals

A builder is a professional

Nope. U clients only value physics work and refuse to pay for designs and estimates. because u think it's all paper. No matter how many free jobs u get u won't still oay

do not use hateful words my brother , lets show love and observe netiquette

Nice

brabus:
Estimating material requirement for the DPC @Sir EgunMogaji site.

I'm more comfortable using metres than feet. So, let's convert the building into metres.

Overall area of the building footprint
50' x 80' or 15m x 24m = 360m²

Overall area of the building footprint less the Courtyard
360m² (Footprint) - 45m² (Courtyard) = 315m²

Volume of Concrete required for the oversite
315m² x 100mm (4in thickness) = 31.5m³

Assuming we are using 1:2:4 mix ratio



___________
Quantity of Cement required

For a 1:2:4 cement mixture, divide the volume (in this case 31.5m³) by 7 to get the resulting number of 4.5m³ of cement required for the project.

Therefore 4.5m³ / 0.035 = 128 bags of 50kg cement.

____________
Quantity of Sand required

For a 1:2:4 mix, divide the volume (in this case 31.5m³ by 7 to get 4.5m³ and multiply by 2 (which is the ratio of sand) to get 9m³ which is the quantity of sand required for the project.

To get tonnage, divide 9m³ by 0.654 which gives about 15tons. Allow for shortage, wastages while transporting/transferring sand and those sand that will be stucked in the mixer. Buy 20 full tons.

_____________
Quantity of Granite required

For a 1:2:4 mix, divide the volume (in this case 31.5m³ by 7 to get 4.5m³ and multiply by 4 (which is the ratio of sand) to get 18m³ which is the quantity of granite required for the project.

To get tonnage, divide 18m³ by 0.654 which gives about 28tons of granite. Buy 30 tons!


________
Oga, Abeg no ask me how I got this figures o! Head nearly blow to work this out. With 1:3:6, you'll use less quantity of cement (90 bags or thereabout). The same quantity of sand/granite should work.

Thank you very much for this. You just helped a brother...

Good one

We supply and hual granite to Benin-City, Delta state, Bayelsa state, Rivers state, Anambra state, Imo state, Eboyin state, Cross River state, Abia state, Enugu state and Akwa Ibom state.

DeniyiBabasola:
Concrete is base on mix ratio. For concrete floor, ratio 1:2:4 is the standard.

That's 1bag of cement, 4headpans of sharp sand, 8 headpans of granite.

The volume of concrete is 36 M cu.

Estimate 150bags of cement, 20tons of granite, 30tons of sand.

Workmanship should b about 100k.( subject to location).

how does 1:2:4 = 1 cement, 4 headpan of sand and 8headpan of granite?? pls explain further


Also , what if i want to use 1: 3: 6?

Thanks
