1. Cubic method:
Advantages:
- This method is simple and easy to understand.
- It is suitable for irregularly shaped or complex structures.
- It provides a more accurate estimate compared to other methods for certain types of structures.
Disadvantages:
- It may not be suitable for structures with varying heights or irregular shapes.
- It can be time-consuming to calculate the volume of each individual component.
2. Functional unit method:
Advantages:
- This method is based on the function of the building, making it easier to estimate costs for different types of structures.
- It allows for a more detailed breakdown of costs based on the specific functions of each area.
Disadvantages:
- It may not be suitable for structures with complex or unique functions.
- It can be difficult to accurately determine the functional units for certain types of buildings.
3. Superficial unit method:
Advantages:
- This method is quick and easy to use, making it suitable for preliminary estimates.
- It provides a simple way to estimate costs based on the total area of the building.
Disadvantages:
- It may not be accurate for structures with varying heights or irregular shapes.
- It does not take into account the specific functions or components of the building.
4. Superficial enclosure method:
Advantages:
- This method takes into account the exterior surface area of the building, which can be useful for estimating costs related to materials and finishes.
- It provides a more detailed estimate compared to the superficial unit method.
Disadvantages:
- It may not be suitable for structures with complex or irregular shapes.
- It does not take into account the interior layout or functions of the building.
Advantages:
- This method is simple and easy to understand.

Cubic Method
Advantages:
- Considers the volume of the building, which is a key factor in estimating costs.
- Relatively simple to use.
Disadvantages:
- Does not account for the complexity of the building design.
- Can be inaccurate for buildings with irregular shapes or multiple stories.
Functional Unit Method
Advantages:
- More accurate than the cubic method, as it considers the specific functions of different building spaces.
- Can be used for complex building designs.
Disadvantages:
- More time-consuming and complex to use.
- Requires detailed information about the building program.
Superficial Unit Method
Advantages:
- Quick and easy to use.
- Can be used for preliminary cost estimates.
Disadvantages:
- Highly inaccurate, especially for buildings with complex geometry or multiple stories.
- Does not consider the height or volume of the building.
Superficial Enclosure Method
Advantages:
- More accurate than the superficial unit method, as it considers the height of the building.
- Relatively easy to use.
Disadvantages:
- Does not account for the complexity of the building design.
- Can be inaccurate for buildings with irregular shapes.
