How to view the cost of prefabricated buildings as higher than traditional reinforced concrete buildings

1. The material cost mainly includes the cost of concrete, steel bars, insulation boards, connectors, embedded parts in components and other materials. Compared with traditional cast-in-place materials, the cost of connecting parts, embedded iron parts, steel bar content and other costs are increased.

2. According to production estimates that are not currently large-scale, the progress of "assembled houses" is about 30% faster than that of traditional construction methods. There is no problem with the safety of the "assembled house", because prefabricated stairs, exterior walls, etc. are transported to the construction site, and reinforced concrete joints are also needed, not simply connected. Steel bars are run through each floor, and the house structure is very strong.

3. Binding of steel bars, etc. These processes require a lot of labor and time, so the construction cost is relatively high.

4. Compare the total cost with comprehensive economic indicators: The total cost of prefabricated buildings is 33,944,0555 yuan, and the single cost is 1,4869 yuan/㎡; the total cost of traditional buildings is 26,184,5846 yuan, and the single cost is 1,1430 yuan/㎡. One-sided difference: Prefabricated buildings are 3339 yuan/㎡ higher than traditional buildings.

5. The situation that prefers traditional cast-in-place houses has limited budgets and low requirements for house performance. The development of prefabricated buildings in the region lags behind, and the level of craftsmanship is in doubt.

Steel structure and concrete cost

Compared with the initial cost, the cost per unit area of steel structures is about 4,000 - 6,000 yuan/㎡ (taking a multi-storey industrial factory building as an example), while the concrete structure is relatively low. The price of steel is about 4500 yuan/ton, and the price of concrete is about 400 yuan/cubic meter. In addition, steel structures require precision processing and steel may be imported, which drives up costs. However, the steel structure has light deadweight and can reduce the foundation cost by 20%-30%, making it especially suitable for soft soil foundations.

Steel structure: Due to the relatively high production, processing and installation costs of steel, the overall cost of steel structures is generally higher than that of concrete structures. Concrete structures: Concrete materials are relatively cheap and construction technology is mature, so concrete structures usually have certain advantages in terms of cost. Advantages of steel structure: Light deadweight: Steel structures have light deadweight, which is conducive to reducing basic cost.

Labor cost: Steel structure frames require less manpower for on-site operation, but require highly skilled workers (such as lifters and welders). The hourly salary is high but the total labor cost is low; concrete frames are labor-intensive operations, and ordinary workers have low hourly salary but the total labor cost is accumulated high due to the long construction period.

Differences in cost between frame structure, brick-concrete structure, and steel structure

1. The main differences in cost between frame structures, brick-concrete structures, and steel structures are as follows: brick-concrete structures have the lowest cost: brick-concrete structures mainly use bricks and concrete as the main load-bearing materials. Because brick and concrete materials are relatively cheap and easy to obtain, the overall cost of brick-concrete structures is relatively low. The cost of the frame structure is moderate: the frame structure is mainly composed of beams, columns and other members, which are used to bear the weight and load of the building.

2. The different cost of different structures is mainly affected by material costs. For example, the price of brick and concrete for brick-concrete is relatively low; the amount of steel used in the frame is large, and the cost of steel structure is higher; the cost of steel structure is increased; the cost of wood structure is not low due to factors such as wood and processing requirements. In addition, labor costs, regional differences, etc. will also have a fluctuating impact on the final cost.

3. Generally speaking, brick-concrete structures are relatively common, and the cost is usually about 1,000 - 1,500 yuan per square meter. Brick and concrete structure is a structural system composed of bricks or blocks, reinforced concrete structural columns, ring beams, etc. It has certain bearing capacity and good stability, is relatively moderate in construction difficulty, and is relatively reasonable in material cost. The cost of the frame structure is about 1,500 - 2,000 yuan per square meter.

4. Overall, steel structures are more expensive. Frame structures come second, and brick-concrete structures are cheaper. Why is this? You can start a discussion. The main material of steel structures is steel, which is a high price. Yunyun.
