Great work here EngrOYemi... I was following the thread in respect to block calculations for projects and all that and it just happened to be a situation I am dealing with. Would you please send me your email so that I can send my plan so as to help me with quantity survey in respect to my project.
Regards

EngrOYemi:


Thank you for following us.

Great job, EngrOyemi. I will mail you my survey plan to help calculate the number of blocks. Etc

ojobek:
Engryemi,I do appreciate the good work you are doing,but my concern is that,I don't think it is proper to assume bond is part of block,10% waste will take care of whatever shortfall that might arise along the line then you calculate mortar for joining (bond) separately.My observation though,thank.

alizma:
Good job

Canme4u:
Well done sir.

This is another Exotic Duplex.

Get busy with this classical designs before we put a finishing touch to the subject matter.

akhaliru:


Engr. How many bedroom duplex is this?

EngrOYemi:
Since we know the total length of all the walls already, therefore it's important to know the Total Area :

The average height of most floors (levels) of building is 3m. But for this context, we are using the height of 3.45m.
Recall Area = L X B = L X H
: Since the L = 91.3m and H = 3.45m
: The Total Area of wall = 91.3m X 3.45m
= 314.985Sqm = 315sqm.

At this stage, we will make some assumptions. Some people called complaining that the floor plan is not so clear and to read the dimensions was challenging. I guess the image was too heavy and the quality was altered by nairaland server.
Let’s assume we have 12 big windows with the dimension 1200mm by 1500mm, 5 Small Toilet windows with dimensions 600mm by 600mm, and 10 doors assuming all the doors have the dimension of 900mm by 2100mm.
Big Window = 1200mm X 1500mm = 1.2m X 1.5m = 1.8sqm
Total Sqm of big windows = 1.8m X 12 = 21.6Sqm
Small windows = 600mm X 600mm = 0.36sqm
Total Sqm of small windows = 0.36m X 5 = 1.8sqm
Doors = 900mm X 2100mm = 1.89Sqm
Total Sqm of Doors = 1.89m X 10 = 18.9sqm
Total Sqm of openings = 21.6sqm + 1.8Ssqm + 18.9sqm = 42.3sqm
Total Sqm of block area = Area of Total Wall – Openings
= 315sqm – 42.3sqm = 272.7 = 273Sqm.
Numbers of blocks = 273/0.12(area of a block) = 2,275Blocks.
Add 10% for cuttings and breakages = 2275 + 228 = 2503 Blocks.
Answer = 2503 Blocks

Remember to use same method to calculate for the numbers of blocks for Strip Foundation but if your Foundation Design type is raft, no need.

ThegreatDon:


Thanks For your time Engr.

The above example you just solved is for calculating no of block for ground floor right? What happens to the first floor and subsequent floors?

EngrOYemi:

Thank you Sir.
We hope to do more but our schedule has really been tight.

Lifebender:


EngrOYemi, thanks for your info sir.
I would love to ask,in bathroom floor construction,do you give it a step down or step up?i.e higher that the room or lower.
Now,I once worked with this guy that steps bathroom floor down when casting.However,the few houses I've lived in,their floors were stepped up.
So what's the pros and cons pls.
