Please can someone tell me how many blocks can one use to fence 2 plot of land (50 x 120). The two plot total (100 x 120)

Bricklayers.

[b]I once posted this, earlier this year; I guess re-posting it will answer your question:


For 1 full plot of land.
All Professional QS and Construction Management Engineers like myself do it like this to calculate the total number of blocks we will use which will serve as #1 basis for other materials, and calculations.

1. Calculate the number of square feet in the fence walls. Multiply the length times the height of each wall. Then add up the results. For example, for a 60-by-120-foot fence, with walls 10 feet high, you have two walls that are 60-by-10 feet and two walls that are 120-by-10 feet. This gives you a total of 3600 square feet.

2. Now, we should consider the gates or entrance that will be left out and which are usually 16ft wide, and 10ft high, giving us a total of 160sq ft. Minus 160sq ft from 3600sq ft, giving us a net wall area of 3440 sq ft.

3. Find out how many 6 or 9 inches blocks fit into a sq ft by the net wall area. Both are about the same lenght, but just differ in thickness, and a sq ft will take 0.85 block. Meaning that a sq ft will take about a whole block. Now, multiply 0.85 x 3600, that gives us = 3,060 pieces of blocks.

PS: This just for blocks to be laid on casted rafted frame work for our fence if the land is dry.

In Lay Man's Language, we will need"

1. 3060 pcs of 6x6 blocks (plus 5% which is an extra 153 extra block, because you will have broken ones) = 3213 pcs x 130 Naira = #417,690.

2. For a simple fence work, 100 blocks = 1 bag of cement x 32.13 plus, extra bags used for foundational work and concrete works that serves as reinforcement = 52 bags of cement x #1800 (depending on cement quality and location) = #93,600

3. For Iron rod I've always calculated 70 leghts for every fence.
Calcultion is far more complex, so wont go into it, therefore 70 lenght of 12mm rod = 70x1300 = #51,000 (plus binding wires and rings) = #55,000

4. Hey, lets not forget the woods that would be used for the framework, we need that too. Meaning, for every single pillars in the wall, you need 4 pcs of 2x4, and 4 pcs of 1x12, my detailed estimation, puts woods within #15,000

5. Sand (4 trucks 10 tonnes each), granite (1 truck 20 tonnes). Prices varies, but one truck of granite is #100,000 firm down here, and 4 trucks of sand makes #80,000 making it a complete total of #180,000

6. Finally, the gate which varies a lot. We have plain sheets, which wont last more than 10 years if superbly coated. And checkered plates which will last longer than your house if well coated. For some uninformed reasons, 90% of homes ive seen use plain sheet, and a gate of such value cost from #70,000 upwards, depending on the wrought iron designs on it. The best gate is checkered gate, and the cheapest with less design goes for around #150,000

7. Now, add up the cost of transporting the materials to the building site. If its close to where building materials are, I am guessing #15,000 most. If not, God help you.


If an individual like me handle it, I happily charge you #150,000 for my charges if the land is dry. I will go higher depending on the level of the water content of your land.

So, simple estimation for a dry land gate = #1,075,690

@aasog1
Experts in the house! Please can someone give me a rough idea for the cost of fencing 100 Acres of farmland in my Village in Ogun State. The land is a compact clay soil which means it would only require a standard foundation.
The quotation will include labour & material cost, and if possible, alternative cost-saving technologies. Thanks

I need a quick estimate on the cost of fencing a 5 walled , 5 1/2 plot of land with low block walls of about 750mm and pillars at 4.5m intervals. The plot here is 60 x 120 ft. Just to go over what I've done. Can anyone help pls. Thank you!

Pls how much is the average pay for laborers and masons, like block carriers per hour, any idea?

pls why didn't you use the net area of the 3440 ft² since the gate would be void
