COMPLETE GUIDE: How To Calculate Number Of Blocks To Fence One Plot Of Land (100 by 50, no pillar)
When we talk about Fencing projects, I know someone would want to wonder why fencing is very important to us. Well, fence is very important as it helps secure your plot of land from encroachment.
Now I am going to write on how you could easily calculate the number of Blocks Required to Fence a Plot Of land with ease.
Do not forget that I have an article describing how to calculate fencing Project but on that post, I chose to use a plot measuring 100ft by 60ft as a case study.
On this current post, I’ll be using a plot measuring 100ft by 50ft but then, it’s all the same procedure except you’ve never been a fervent reader here.
So how do we calculate the number of blocks required to fence one plot of land?
From this Post, You will get to know:
The number of bags of cement needed for this project,
Amount of sharp sand that will be required as well as the
Number of trips of granite you’ll need
The simplest way to calculate the numbers of blocks you need for your fence project, assuming you are fencing a land measuring 100 feet by 50 ft, a standard plot
This calculation is based on 6 inches block fence and by the time I’m done, you’ll only need to ask your engineer when he’s commencing work on your site.
How To Calculate The Number Of Blocks To Fence One Plot Of Land
Before we start, lets understand The measurement we are using is 100 ft (length) and since we have two lengths that is multiply by 2 which is 200 ft. (10 x 2) = 200
The breadth is 50 ft and also since we have 2 breadths that equal 100 ft (50 x 2) = 100
Then (200 + 100) that is 300 feet perimeter line fencing.
The calculation For Number a of Blocks Goes Thus
(we are to convert this 300 feet to inches ) since a foot is 12 inches , now let us multiply 12 inches by 300 ft which is 3600 inches.
Now to get the line numbers of blocks that will go around the fence perimeters of 3600 inches or 300 feet, we would need to divide 3600 by 18 inches, since the length of any block be it 6 inches or 9 inches is 18 inches.
Now 3600 inches divided by 18 inches is approximately 200 line of blocks , then we must multiply that by the numbers of coaches of blocks you want for your height, assuming 7 ft which is 9 coaches that means 200 multiplied by 9 which is 1800 blocks and that is all you need anything aside from this is fake and fraud.
Note: Its always recommended that you make an allowance by adding 10% of the total number of blocks to cater for breakages but you can still decide to work with just 1800 since I know we didn’t leave space for joints.
Now let’s consider other things
Now that we’ve known the number of blocks required to fence a plot of land, the next question would focus on ascertaining the number of bags of cement that would enable us bond the 1800 blocks calculated above.
HOW MANY BAGS OF CEMENT WOULD BE REQUIRED TO BOND THE 1800 BLOCKS?
In our normal English we call the act of bonding Setting of block
By standard, it is required that a bag of cement be used for 70 blocks (it could be lower if you’re using hollow blocks)
Therefore, for 1800 blocks, you’ll need 1800/70 = 25.71 bags of cement or approximately 26 bags of cement.
Note: This highly depends on the mix ratio used for mortar. Mix ratio could differ, it all depends on the engineer on site.
As For the number of Trips Of granite you’ll need, it all depends on what your pocket can carry.
While I recommend that granite be incorporated into the foundation concrete, it’s not compulsory that it be used. This of course depends on where you are, for a plot of land situated in a highly swampy area, casting is very compulsory, it may even be decided that reinforced concrete be used before introducing blocks.
Well, I hope I’ve been able to describe in details how to easily calculate the number of blocks required to fence your plot of land in Nigeria, especially for a 100 by 50ft plot.
