More from the foundation block work

As I can see from the angle of courses of block laid which just two, the total number of block used to achieving this level should be 432 numbers of block

very neat job as usual my able engr.

my questions;
is it 196m or 96m?
how many bags of cement, tons of sand and gravel did u use for the footing?
thanks.

According to the info provided at prior as:
Girth=96m
Width of footing=675mm
Depth of footing=150mm
mix=1:3:6

Sum mix ratio:1+3+6=10
Dry Volume: 96×.675×.150=9.72m^3
Wet Volume: 9.72×1.25 (1+.25 for bulking and shrinkage)= 12.15m^3
1÷10×12.15×1440=1749.6kg
Since 1 bag of cement =50kg
Therefore, bags of cement to be used: 1749.6÷50=34.99bags
Pls Engr. Kindly make your corrections if needed.

Due to the nature of the soil, it was very difficult to dig more than 450mm to around 500mm. The soil is stiff clay and the site is relatively higher than the road.

Casting of foundation
1. Total length of strip footing =96m
2. Width of footings =675mm
3. Depth of footings = 150mm
4. Mix ratio =1:3:6 (by mass)

If am correct as the info provided above, you must have used 27.99bags of cement (strictly predicted base on mixing proportion inscribed)

Yea, when do you want us to talk?

Shall we on whatsapp?

It is a simple mathematics my oga. 25 percent of A is 0.25A, while and increase of 25% of A = A + 0.25A = 1.25A

Thank you Engineer

Please I want to work under you as a junior colleague sir, I shall be glad if this request is giving special attention. My zeal for construction is gradually going down as the result of job placement inadequacy, as the matter of fact, would like to be with to exhibit the rightly. Thanks !

Engineer!
Can we talk in camera ?

Good day ! I had sent you a message over the analysis u did for a boungalow foundation at a particular aspect calculating for volume increasingly by considering 25% (as 1.25) all because of the shrinkage and wastage. here i want to ask, is 25% converting to 1.25?

Good day ! have reached u through mail but i could not get it through, i have a question over one of article you composed ''Proper Analysis of design and cost of a foundation design for boungalow''
There i found shrinkage and wastage of 25% to increase the volume of concrete, which you later calculated as: 1.25 (25%) x (girth x width of the trench x thickness of the foundation footing).
Here, i want to know if 25% was 1.25 in conversion ?
