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

@abdnasserssessimba2401 6 месяцев назад

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 6 месяцев назад

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

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?

@shiekjk3092 3 года назад

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.

thickness of block, to get the in to in dimension

@afeezaremu3906 3 года назад

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

@kolawoledavid Год назад

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

@afeezaremu3906 3 года назад

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

@kolawoledavid Год назад

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

@clovisbala5328 2 года назад

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

@nhlanhlazikalala3478 2 года назад

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

@moriceug 2 года назад

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

@jmsure1 2 года назад

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 2 года назад

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 😅

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

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

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.
