Example of RAB for a 2-storey house and how to calculate it
In the construction of a house, it is necessary to calculate the right budget so that the construction process can run perfectly. Especially if you want to build a 2-storey house, then you need to calculate the RAB for a 2-storey house.
RAB (Budget Plan) is something you need to prepare when you want to build a house. With the RAB, you know what costs are needed to build a house at the final stage.

How to calculate RAB for a 2 storey house
Before doing RAB, it is necessary to know how to calculate proper RAB. This is so that the budget that you prepare later is not over budget in building a house.
Here are the general steps you can take to calculate a Budget Plan (RAB) for a 2-story house:
1. Design Plan and Specifications
Before starting to calculate the RAB, you must prepare a complete design plan and construction specifications. This includes the number of rooms, the size of the room, the type of materials to be used, and also other technical specifications.
By making a design plan and specifications, it will be easier for you to do the RAB right after.
2. Determine the general Budget
As a basis for the subsequent RAB calculation, you need to determine the general budget after knowing the design and specifications. The overall budget will help you make the right RAB and what is not over budget.
Make sure the budget includes all the materials and designs that will be made later.
3. Calculate the cost of Materials and services
After determining the general budget, you need to calculate the cost of materials and services needed to build a 2-story house. Material costs include various building materials such as concrete, bricks, glass, pipes and more.
Meanwhile, service fees include labor costs for masons, carpenters and electricians.
4. Calculate Additional Costs
In addition to these costs, you also estimate other additional costs that must be considered. These additional costs include transportation costs, administrative costs, and tool and equipment costs.
5. Total cost of each job
After calculating the cost for each item, group the items by type of work such as land preparation, structural work, architectural work and labor. finished. Then add the costs for each type of work and add all the costs to get the general budget (RAB) for the construction of your 2-story house.

- Volume: the amount of work done, in certain units
- Unit: unit of work volume, for example square meters (m2), fruit, cubic meters (m3), etc.
- Unit Price: the price applied to each unit of work
- Total Price: the total cost for a particular job, calculated from the volume and the unit price
- Total Cost: the total cost of all the work done on the construction of a 2-story house.
It is important to remember that the RAB can vary depending on the location, the materials used, labor costs and other factors that affect the cost of building a house. Therefore, the RAB must be made based on careful and specific calculations for the project being carried out.
So the discussion about the 2-story RAB house you need to know. It is important for you to make an accurate and precise RAB so that the construction of your house goes smoothly. I hope this article is helpful!
