Furthermore, if you want a building to be very strong and long-lasting then you have to take note of the foundation.
Moreso, While there are many factors to put in mind when planning to initiate the construction of the foundation of a building, one of the core things to estimate is the overall cost of the foundation construction process.
In this article, we will take a quick look at how much it will cost to construct the foundation of a 3-bedroom flat in Nigeria today.
Cost of Foundation for 3-Bedroom Flat
There are so many factors that determine the estimated cost of the foundation of 3-bedroom flat. Factors like the price of various materials to be used, location of the site, labour cost and so many other factors affect the eventual cost of a foundation.
More so, we can largely estimate how much the whole project could cost. To make this simpler, we will take a look at the expected cost of constructing a foundation for a 3-bedroom flat in Nigeria.
Cost of Setting Out with Profile
This is the first stage in constructing the foundation. Here, you are expected to use so many materials including planks, pegs, nails, and many more. Below is the estimated cost of this process.
- Plank – 5 pieces of Plank (1 by 12) – This costs between ₦7,000 – ₦10,000 depending on the location
- Pegs – 5 bundles of pegs – This costs between ₦8,000 – N9,500 depending on the location
- Nails – 2 inches and 3 inches – These cost between ₦2,000 – ₦4,000
- Rope – 4 bundles – This costs between ₦900 – ₦1,500
- Cost of labour – This largely depends on the strength of the labour force you have employed. You can expect to spend between ₦9,000 – ₦12,000
Cost of Digging and Excavation
This stage which is the digging process, It does not require so much. While some estimates for this process with the profiling process, it is usually advisable to separate the estimation. The major cost required here is labour. You expect the labourers to have their equipment. You can estimate between ₦20,000 – ₦35,000 depending on the strength of the labour force you got for the digging.
Cost of Binding
This is where the concrete work cokes in. A typical foundation is about 150mm thick on the base, having a height of 0.45 meters and a length of 85.5 meters. Below is the estimated cost of this stage.
- Cement – 10 to 12 bags of cement. This costs between ₦40,000 – ₦54,000 depending on the location
- Sand – 20 tons of sand – This costs between ₦100,000 – ₦120,000 depending on the location
- Granite – 20 tons of Granite. This costs between ₦120,000 – ₦150,000 depending on the location
Mostly in this stage, Iron bars might not be necessarily required, especially if the soil is firm enough, which is usually the case in most places.
Also, if the workers have direct access to water, like a well or borehole around the site, then there wouldn’t be any need to estimate the cost of litres of water that would be required. You can estimate between ₦35,000 – ₦40,000 for labour
Based on these, you should expect to spend between ₦370,000 – ₦450,000
Cost of Laying Foundation Blocks
After you are done estimating for the concrete work, you can pay attention to laying the foundation blocks or bricks. If you will be using 9 inches blocks and laying four coaches, which is the norm these days, you will need the following;
- Cement – 12 to 14 bags of cement – This costs between ₦48,000 – ₦60,000
- Vibrated Blocks – about 650 pieces – This costs between ₦150,000 – ₦170,000
- Work relating to plumbing – This should cost between ₦35,000 – ₦55,000
Based on the estimate above, it is expected that the sand and granite remaining from the concrete work to be enough for this stage. Therefore, we do not need to Budget for another sand or granite for this process. For this step it is good to budget between ₦45,000 – ₦60,000 for labour bcos it requires hard work.
Cost of Filling and Foundation Casting
When you want to plan for this process, it is a process that is always economical because it is the process of digging the soak away. This is because the sand gotten from the digging of the soak-away will be used for the filling. By so doing it helps in saving cost. Below is the estimated cost of this process.
- Cement – 25 bags – This costs between ₦100,000 – ₦112,500
- Nylon – This costs between ₦19,000 – ₦23,000 depending on the location
- Laterite – About 3 trips of 20 – 22 tons – This costs between ₦75,000 – ₦100,000 depending on the location
- Labour – You should budget between ₦45,000 – ₦60,000
More so, we expect the sand and granite remaining from the concrete work to be enough for this process. Hence, we do not need to budget for another granite and sand.
