1. Definition: Optional prefabrication rate and industrialization rate
2. The industrialization rate is calculated as follows:
Industrialization rate = 0.8 × prefabrication rate + 0.15 × assembly rate + 0.05 × finished product rate
The prefabrication rate measures the use of prefabricated components in structural elements. Key components include beams, floor slabs, columns, structural walls, balconies, air conditioning panels, stairs, and peripheral protective walls.
The assembly rate reflects the use of prefabricated components in other parts, such as internal partition walls, flues, shafts, and railings. It is recommended to calculate this based on volume, as calculating separately by area or quantity may not accurately reflect the combined indicator.
The finished product rate indicates the application of integrated decoration and internal facilities, including integrated kitchens, bathrooms, and similar features. Specifically, integrated decoration accounts for 0.02, integrated bathrooms for 0.02, and integrated kitchens for 0.01. It is advisable to include all these in the calculation.
3. The proportions of the prefabrication rate and assembly rate can be adjusted moderately to reflect the direction of technological progress.
4. For steel structures or steel-concrete composite structures, when both beams and columns are made of steel, the prefabrication rate for beams and columns is calculated as 0.2. Although the actual prefabrication rate may be lower, this higher value is used to encourage the adoption of steel structures. The remaining components are calculated using the prefabrication rate for concrete, excluding the volume of steel beams and columns, which effectively increases the overall prefabrication rate for steel structures.
