[@m-squarem2815]

Thanks bro! Hope more to come

[@redbee6918]

Great thanks to you sir, I would like you to also talk about how to calculate the quantity of sand and cement.

[@abdullahiidrisyaba7953]

This was educative... thankyou

God bless you good work boss

[@jacobanimgyampo446]

GREAT WORK! ...what about the mortar space? again what are you going to use the internal girth for?

[@otutu2000]

You should have explained how you got the 4/2/.5/225

[@noluthandochantelle4849]

I also wish to know that

[@user-ps8sr1hg7d]

Yes please 🙏

[@paschallaurent7558]

4 for four items 2 for two half on each wall 1/2 half of the wall or block thickness 225 block thickness

[@alexanderoyije8247]

We really appreciate. Please produce videos for superstructure taking off too.

[@Orshiojames]

U are good keep it up

[@combobulationstation]

Very helpful video thank you but at 15:00 the final measurements on Door 2 being 0.90 x (2.10+0.225) x 2 = 2.09m2? did you accidentally forget to times by 2 or have I missed something?

[@gnanamdhasthasian445]

Good explanation.... What is the meaning of the word you used procon.

[@samuelmambu2756]

thanks so much may the Lord bless but please explain how we achieved the 4/2/5/225 , please do same for roofing

[@sojconsult7961]

For the internal mean girth, you used the internal dimensions of 5,600 and 4,600. I think you should have use the IN to IN approach I think u should Add 2/2/1/2/225 to it, am I right?

[@chukwunonsophene7550]

From your external main guide, how did you calculate it??

[@paschallaurent7558]

Awesome

[@peterogunyemi76]

Interesting great job may Almighty bless you

[@qsacademy]

Amen. Thanks

[@peterogunyemi76]

Please we need more of this take off to broaden our knowledge.... Thanks so much

[@OluwaseunAdetifa-wl2iu]

Kudos

[@abdnasserssessimba2401]

HI Engineer, you have calculated the number of blocks thanks for that i have gained alot but you have taken the floor plan as a full rectangle yet there is a portion on the plan which don't have block work . do i need to less the area for this portion?

[@qsacademy]

Yes. There is usually a need to less any portion without blockwork. For example, lintels, beams, door and window openings, and even entrance porch/veranda recess

[@Orshiojames]

And pls do us well by taking off for roof pls

[@shiekjk3092]

Adding and subtracting of four conners is only for the calculation of the main girth from what I understand, is that correct sir ? Because you didn't add four conners after calculating the internal girth.

Please what will be the volume of the mortor only? kindly extract the volume of the mortor separately for me. Thank you

[@umoeravincent6407]

How many blocks can build one room tell me

[@annexkidula9184]

In external min girth, where do we take measurents, is it from center to center or in to In. thank u sir

[@qsacademy]

Out-to-Out

[@cocoayvert8637]

Please sir i don't understand where 4/2/0.5/ is coming from

[@Orshiojames]

And pls do us well by taking off for roof pls 4:28

[@isaacbissah3035]

Nice explanation But my question has to do with the mortar joints. What happens to that, is it not to be deducted too since it also influence the height of the building?

[@Rodan_05]

O the 10 mm mortar joint.

[@ambassadorvictortv8463]

Nice one but i can i get number of cement in a particular buldin

[@annexkidula9184]

Thank you for your teaching sir, what about when my dimensions are from center to center hw do u do with outer min girth with deductions of 4/2/(225,1/2)

[@qsacademy]

Yes For Out to out you will deduct Centre to centre no deduction In to in you add

[@annexkidula9184]

Thank u sir I got it right

[@edrissandow490]

hi, plz i found it difficult to calculate STEP 3.

[@afeezaremu3906]

and also how did u get the calculation of opening door and window

[@kolawoledavid]

It's very simple,just multiple the height and width of the door or window and add .225 ,then multiple by the total numbers of windows or doors of the same dimensions. Later sum everything up together. Thanks

[@redbee6918]

The 900 you deducted in step one, represents what? and why did you less it?

[@qsacademy]

I've explained this concept in this my video; kzbin.info/www/bejne/noKZgKiNapKHiJI Watch it and you will probably understand why I did that addition. I hope this helps....

[@afeezaremu3906]

please how can i calculate two bedroom flat and the length is 11025 and also the brength is 20825

[@kolawoledavid]

Having the length and width alone won't give you the total numbers of blocks to use sir because there are other partition (internal walls) inside the drawing which are meant for toilets, kitchen,rooms, dinning etc. But with the illustration of what he did you can get it. You can not get the total numbers of blocks to use for a two bedroom flat like that without looking into the internal dimensions. Thanks.he will give more details if he get to see your comment sir. I am just a colleague in the profession who acknowledge what he's doing

[@user-no1ti1ql7q]

4:06 can u please teach ur less 4/2/1/2/225 I don't understand it

Watch my old video on how to calculate mean girth of a building

[@siphesihlensele473]

when did you get the height of lentel! ....I like to thank you for all information you gave us may God bless you

[@qsacademy]

The height of lintel is usually 225mm or in some cases 150mm. It's a constant value. Thanks for the feedback.

[@ernestyusuf6299]

[@qsacademy]

It is a regular shape

[@syedfathullah6128]

Dear bro what is the mean of "less (4/2/1/2/225)".Please describe briefly

[@clovisbala5328]

What you mean the super structure and sub structure is calculated independently

[@nhlanhlazikalala3478]

I think by substructure he's referring to any low walls you may have inside the house e.g. support for built-in cupboards, bathrooms, etc

[@user-no1ti1ql7q]

Please u need how u got the 4/2/1/2/225

[@user-ps8sr1hg7d]

Where does "less 4/2/.."comes from?

thickness of block, to get the in to in dimension

I'm just watching ur video Weldone sir.... but...when calculating for the openings and lintels the last calculations is wrong sir

[@user-no1ti1ql7q]

I don't understand the less 4/2/1/2/225

[@moriceug]

Why didn't you deduct the area where no block walls

[@talkcivil]

Why didn't you consider the mortar spaces?

[@qsacademy]

because the mortar spacing is usually considered during the estimation of its unit price

[@talkcivil]

@@qsacademy okay.

[@setjhabaphillipmotsoeneng3917]

Anyone pls who understand where this 4/2/.5/225 come from maybe volunteers will explain better for me,cos its where I'm lost pls

Check out this my video on Mean Girth Calculation. It explains where those figures came from. I hope this helps. kzbin.info/www/bejne/noKZgKiNapKHiJI

[@evachristian3029]

Don't understand the calculations you did at the door , window and lintel it gave me different answers

[@shiekjk3092]

The values, in what unit are they? Are they in ( ft or mm or m inches?) Pls sir be playing with the units pls sir.

[@qsacademy]

I started with mm then converted it to m to get my final values

[@shiekjk3092]

@@qsacademy thank you so much you are Really helping people around the world. Pls be explaining the converting unit and point for us the beginners pls sir.

[@kolawoledavid]

The values are in meters

[@jmsure1]

Really no need to subtract the area taken by lintels because you will not purchase half or three quarters of a block anyway. You have to buy complete blocks

[@nhlanhlazikalala3478]

I also saw that, however I think he was trying to calculate total open space, as you could see he wasn't even pleased with leaving out the overhang 😅

[@ososanifedapo]

The void spaces in ur drawing wasn't deducted sir Isn't it necessary

[@qsacademy]

The void does not affect the blockwork because the only unit needed for calculating the block qty is perimeter length and height. Note that the void will only affect work items covering the floor area or volume.

[@ososanifedapo]

OK sir Many thanks for this Great job God bless

[@lekanwusu1912]

The price of your courses on Udemy is too expensive, reduce the price to 15-18 pounds and you will get more students.

[@qsacademy]

Thanks for your suggestions. I usually adjust the price to the lowest amount attainable on Udemy from time to time.

[@Boj_crypt]

What is he even saying

[@shiekjk3092]

Adding and subtracting of four conners is only for the calculation of the main girth from what I understand, is that correct sir ? Because you didn't add four conners after calculating the internal girth.

[@qsacademy]

Watch this my video on mean girth and you will understand why we less or add corner in mean girth calculation. It will show you that the adjustment for 4 corners is meant for external girths depending on the type of dimensioning used... kzbin.info/www/bejne/noKZgKiNapKHiJI
