Are you planning of fencing your land? Do you want to know the cost of fencing 2 plots of land in Nigeria?
If yes, then, I have done the bill of quantities for you. I have carefully estimated the cost of fencing 2 plots of land here in Nigeria. Also, I have explained the process in detail in this article.
Please note: do not by any chance use the price of materials used here as a base, because prices vary from places to places. Alternatively, contact a quantity surveyor for costing or for preparing the bill of quantity for your project.
After a successful purchase of any property, the next important step you should take is to get the survey plan done and also fence the entire area.
This is generally advised to be done immediately after acquiring the property, because it shows ownership has changed hands, secondly it helps the buyer to secure the property in case if the seller happens to be a dishonest person.
But then, in other to get the fence erected immediately after the purchase, the buyer needs to plan for it. That is to say, budget the cost of the land, the survey plan, the fencing, other fees, and also some unforeseen expenses that may arise.
Meanwhile, the cost of fencing a land depends on the nature of the land and the topography of that land too. For instance, if you were to fence a land in a swampy area or waterlogged area, the cost of fencing it is going to be high to compare that of the dry land.
Having said that, the cost of fencing a land is determined by these factors: the land size, the topography of the land, the location, height, and quality of blocks to use.

The estimated cost of fencing 2 plots of land in Nigeria
There are different measurements when it comes to measuring a plot of land. Different cities or states in Nigeria measure at different rates.
Some state measures 50 by 120 feet for a plot of land while other state measures 60 by 100 but Lagos state measures 1 plot of land to be 60 by 120 feet which is equivalent to 648sqm. I will be using Lagos state measurement on this exercise
So the total size of 2 plots of land is 120 by 240 feet which is equal to 1296sqm. This simply means, on a plot of land, the two breaths are 120 + 120, and the two lengths are 240 + 240 feet.
The cost estimate will be derived in 4 different stages or sections of the projects such as:
 Clearing and Excavating stage
 Pouring of the concrete, which includes: cost of materials and labor.
 Laying of blocks stage
 Finally, fixing of the Gate and the 2 pillars that hold the gate

cost of Excavating and clearing a 2 plot of land
The first thing to do before fencing a land is to clear the ground after the beacon area has been established by the surveyor. Next is to excavate the part for fencing. The term “excavation” means the act of digging a mapped portion of the ground to be fenced.
The cost of clearing and excavating the land is determined by, the size, the equipment to use, the depth of the excavation, the location of the land, and the people involved.
Hence, to calculate the cost, below are the breakdown
how to calculate the cost of Excavated area to be fenced on 2 plots of land
Depth of the area to be excavated: 0.6m which is equivalent to 1.9885ft
Width of the area to be excavated: 0.675m which is equivalent to 2.2145ft
The total length of the land is 1296sqm which is equivalent to 120 + 120 + 240 + 240 = 720ft or 219.456m. We will remove the area where we will put the Gate which is 12ft because we don’t need to excavate those areas.
Now to get the total area that is to be fence: 720ft – 12ft = 708ft or 219.456m – 3.6576m = 215.7984m. This simply means that the total length of the area required to be fenced is 215.7984m.
Note: in this article, we will maintain the use of meter (m) for all the calculation because is the standard.
Thus, to calculate the cost of excavation you will multiply the “depth” * “width” * ” total length of the area to be fenced”. Which is 0.6m * 0.675 * 215.7984m = 87398.352m.
The rate of excavation ranges from ₦700 to ₦1000 per meter depending on the location. On this project, I will be using ₦800 as the rate.
The labor cost is negotiated per cubic meter.
Therefore, the labor cost of excavating the total area of 215.7984m is [800 * 216 = ₦172,800]. While the cost of clearing a 2 plot of land ranges from ₦50,000 to ₦80,000 depend on the negotiation.
So adding the cost of clearing the ground and the cost of excavation will amount: 50,000 + ₦172,800 = ₦222,800 or $584.78

Cost of pouring and mixing the concrete footings
Pouring concrete footings simply means an act of dropping a mixed concrete (which includes: cement, sand, and concrete) on the excavated portion to be fenced. This is done to create a level surface on the foundation that is to hold the block fence.
Some of the materials needed to mix the concrete are cement, sand, and granite. In building construction there are recommended ratios for mixing the concrete, which is 1: 3: 6; and 19mm aggregate of granite.
This ratio simply means you are to use 1 bag of cement with 3 headpans of sand and 6 headpans of granite when mixing the concrete footings. Also, the size of granite to be used for the concrete is 19mm.
Now, in other to find how many of this material will be needed for the concrete footings on a total length of 216m
Calculation: to determine the number and volume of material needed for the concrete
The total length of the area to be fenced is: 216m
The sum of the ratio is: 1+3+6 = 10
The width of the excavated foundation is: 0.675m
The thickness of the mixed concrete is always between 0.05m to 0.1m for a dry and level ground but for sloppy ground or foundation, it varies.
To find the total volume of the concrete footings needed you have to multiply “the total length of the fence” * “the width of the excavation” * “the thickness of the concrete”. Which is: 216m * 0.675m * 0.1m = 14.58m.
To find how many bags of cement needed for the concrete footings on the foundation. You will use the constant to divide the arithmetic result between the total volume of the concrete and the sum of the ratio, below is the result.
The total volume of the concrete divided by the sum of the ratio: 14.58m / 10 = 1.458
Taking a constant 0.035m for a volume of a bag of cement.
Thus, total bags of cement needed for concrete footings: 1.458 / 0.035 = 42bags
To find the volume of sand needed for concrete footings, you multiply the ratio of the sand with the arithmetic result between the total volume of the concrete and the sum of the ratio, below is the result.
The result of the total volume of the concrete and the sum of the ratio, multiply by the sand ratio: 1.458 * 3 = 4.374m. Taking a volume of one trip of sand to be 3.8m.
Therefore, 4.374 / 3.8 = 1.15m. This means we need one and a half trips of sand for the concrete.
For the volume of granite needed, you multiply the sand ratio with the result of the total volume of the concrete and the sum of the ratio: 1.458 *6 = 8.748m.
Thus, the volume of the granite needed is 8.748 / 3.8 = 2.303m. This means we need about two and a half trips of granite for the concrete foundation.
Cost of labor and materials needed for concrete footings
Having determined the volume of material needed for the concrete work, next is to establish the cost of them.
From our calculations, 42bags of cement will be required to do the concrete. One bag of cement is ₦2,800.
Therefore, 42 bags of cement cost: 42 * 2,800 = ₦117,600.
For sand we need one and a half trips of sharp sand, one trip cost ₦25,000.
Therefore, one and half trip of sand will cost: 25,000 + 12,500 = ₦37,500.
For granite, we need two and a half trips, one trip cost ₦30,000.
Hence, two and half trip of granite will cost: 30,000 +30,000 + 15,000 = ₦75,000.
Cost of labor for concrete footings: labor cost is determined by the number of bags of cement used for the mixed concrete. At the same time labor cost varies from location to location and from individual to individual, also is a factor of negotiation. The price ranges between ₦800 to ₦1,000 for one bag of cement
Therefore, labor cost for 42 bags of cement will be 800 * 42 = ₦33,600.
In general, the total cost of materials and labor for mixing & pouring the concrete on the excavated ground are: ₦117,600 + ₦37,500 + ₦75,000 + ₦33,600 = ₦263,700 or 692.13

Cost of laying Blocks for 2 plots of land
After the concrete has been poured the next thing is the laying of the blocks. Before that you will need to know the height you intend to level the fence, with that you will then determine how many coaches of blocks that will be required, also how many blocks that will be needed to reach the height.
Meanwhile, coaches simply mean the laying of blocks level. For example, when you lay one block on the ground it is referred to as one coach when you lay another block on top of it that is referred to as second coaches, and so on.
On this project, our target height is 12ft. This will require about 12 coaches of blocks, two coaches will be buried on the ground as the foundation, while the remaining ten coaches will be the fence wall.
Note: the height of the fence you intend to build will determine how much it will cost to complete the fencing also the number of blocks that will be required.
How to calculate the number of blocks needed to fence 2 plots of land  how to calculate blocks for fence
Remember the total length of the area to be fenced is: 216m
The length of any given block is always 450mm or 0.45m which is equivalent to 18inches.
The width of any given blocks varies, the commonly used ones are 6inches (150mm) block or 9inches (225mm) block.
How to calculate the number of blocks to be laid on the fence
To determine the number of blocks that will cover the first blocklevel or coach is by dividing the total length of the area 216m by the length of a block 0.45m.
Which implies; 216m / 0.45m = 480 blocks.
From the calculation, it is clear that it will take 480 blocks to level the first coach on the ground. Therefore in other to level the fence to 12feets height which is 12 coaches, you have to multiply 480 by 12.
Hence, 480 * 12 = 5760 blocks.
This simply implies that it will take 5,760 blocks to level a fence of 2 plots of land with the height being 12 feet.
How to calculate the number of pillars (columns) to use on the fence
On this project, we will take the distance between one pillar to another to be 3m. So in other to get the number of pillars or columns the fence will carry, we will have to divide the total length 216m by the distance of each pillar or columns 3m.
Therefore, 216m / 3m = 72 pillars (columns)
This implies that to fence the total length of 216m of 2 plots of land it will take 72 pillars (columns). We will minus two pillars that will be used on the gate because those two will use reinforcement. This will give 70 pillars.
Please note: we use blocks for the pillars (columns) instead of an iron rod (reinforcement) because is dry land. If it were to be a swampy area or waterlogged area it is advisable to use reinforcement.
How to calculate the number of blocks to be used on the pillars
To get the number of blocks for one pillar; it will be 1 block multiply by the number of coaches, in this case, is 12 coaches.
Thus, 1 * 12 = 12 blocks for one pillar.
So to get the number of blocks that will be used on 70 pillars (columns), we multiply 12 blocks by 70.
Therefore, 12 * 70 = 840 blocks for the pillars.
Hence, we will need 5,760 blocks for the fence plus 840 blocks for the pillars. Which in total is 5760 + 840 = 6,600 blocks.
Note: always budget for damage blocks.
Cost of blocks, cement, sand, and labor work
We will be calculating the cost of blocks, cement, sand, and labor for this work
Blocks: cost of one 6 inches block is ₦180 while that of 9 inches is ₦200, although it depends on the area or location.
We will be using a 9 inches blocks on the projects also the blocks will be purchased from the factory.
So for 6,600 blocks, it will cost 200 * 6600 = ₦1,320,000.
Note: it is advisable to always mold the blocks onsite for quality purposes. Also if you were to mold the blocks onsite the cost will be cheaper.
Cement: cost of cement that is required to lay the blocks. We will divide the total number of the blocks by 50.
This will give 6600 / 50 = 132 cements.
One bag of cement is ₦2,600, multiply it by 132 bags of cement, it will result in 2600 *132 = ₦343,200.
Sand: we will need sand to mix with the cement in other to produce mud. 10 tons of sharp sand will be needed. The cost of sharp sand 10(tons) is ₦25,000
Labor work: the cost of labor for laying one block is between ₦60 to ₦80.
Therefore, the cost of laying 6600 blocks is 60 * 6600 = ₦396,000.
Hence total cost of laying blocks on the excavated portion on a 2 plots of land with the height of the fence been 12ft is: ₦1,320,000 + ₦343,200 + ₦25,000 + ₦396,000 = ₦2,084,200 or $5470.34

Cost of the gate and the two pillars (columns)
After finishing the laying of the blocks to 12 feet height the next thing is the mounting the two concrete pillars and fixing of the gate.
We will need the following materials for it
 Granite: we purchased two and a half trips of granite during the time of concrete foundation. So we are going to use part of it here too
 Cement: we will need about four bags of cement for the 2 concrete columns. Each bag cost 2600. So for 4 bags will be: 4 * 2,600 = ₦10400
 Sharp sand: we will make do with the sharp sand bought during the foundation concrete.
 Planks: we also need planks to make the column firm after pouring the concrete. About 10 tons will be ok, which cost ₦10,000
 Iron rod: we need 3 lengths of 16mm iron rod for the 2 big pillars holding the gate, which cost ₦15,000
 Gate: a good quality gate ranges from ₦150,000 to ₦5,000,000.
Now let’s calculate the cost of labor.
Since the number of cement to be used is 4. Therefore the labor cost for mixing the cement for concrete is 4 * 600 (remember 600 is a cost of labor for a bag of cement) = 2400. Adding the cost of pouring the concrete to the pillar: 4,000
Also, the cost of carpentry work and setting of the gate is 15,000
Therefore the total cost of labor is: 2400 + 4,000 +15,000 = ₦21,400.
So let’s add the total cost of materials and labor: ₦10400 + ₦10,000 + ₦15,000 + ₦150,000 + ₦21,400 = ₦206,800 or $542.78
Conclusion: the estimated total cost of fencing 2 plots of land in Nigeria
In other to get the total cost of the whole fencing project, we will need to add all the above costs together.
Hence, ₦222,800 + ₦263,700 + 2,084,200 + ₦206,800 = ₦2,777,500. Or $7290.03
This simply means that, if you are planning of fencing 2 plots of land with the height as 12ft, you should budget from ₦2,777,500 above.
Note: always budget for unforeseen expenses also on this cost I didn’t factor in the cost of water to be used on the site.
Why you need the service of a QS for costing your project
Knowing the cost of a project before commencing on it is so important. It helps the owner to plan or budget financially on how to go about it before starting the project. That is, know the time frame, how and when to start, who to use for the project, and the best time to start.
Also, it helps to avert project abandonment which is becoming a norm here in Nigeria. That is why I strongly advise anyone who intends to start any building projects to quickly engage the service of the quantity surveyor (QS) for the bill of quantities.
Honestly, that is the best step to follow before starting any building project. Sometimes people tend to shy away from their services because they don’t want to spend money.
The question is, is it better to start a project and get it abandoned or ends it halfway than to pay a QS and get it done within your time frame and budget?
The answer is yours. Meanwhile, if you need the service of a quantity surveyor (QS), we have experienced professionals that will give you a good bill of quantities for your projects.
