Cost Composition of Prefabricated Houses Includes
The cost composition of prefabricated houses mainly includes material costs, mold costs, transportation expenses, installation costs, foundation treatment costs, production costs, design costs, and other expenses.
Material costs are the fundamental part of the cost of prefabricated houses, covering basic building materials such as cement, steel bars, and sand and gravel, as well as specialized materials for walls, roofs, and decorations. The quality and type of materials directly affect the price. For example, there are significant price differences between high-quality steel and ordinary steel, and between high-quality cement and general cement. High-end decoration materials can also substantially increase costs.
Mold costs stem from the high dependence of prefabricated component production on molds. Although molds are a one-time investment, they need to be amortized into the cost of each house. Their price is influenced by the material, process complexity, and degree of customization. Projects with small batches or high customization requirements have a higher proportion of mold costs.
Transportation expenses are a significant expenditure item due to the large volume and heavy weight of prefabricated houses. Transportation costs are usually calculated based on kilometers traveled, cargo volume, or weight. They are also subject to restrictions such as road height and width limits. Cross-province transportation costs increase significantly, and remote areas or special road conditions may further drive up costs.
Installation costs include equipment rental, labor costs, and expenses for on-site lifting, splicing, and fixing procedures. The proficiency of the construction team, installation efficiency, and quality directly affect costs. Inexperienced teams may lead to rework or extended construction periods, indirectly increasing expenses.
Foundation treatment costs depend on geological conditions. Prefabricated houses have clear requirements for foundation flatness and bearing capacity. Common treatment methods include pouring concrete cushions or strip foundations. Soft soil foundations or complex geological areas require additional reinforcement, and costs vary greatly by region.
Production costs are closely related to production processes, equipment investment, and production efficiency. Highly automated production lines can reduce labor costs but require significant initial equipment investment. Traditional processes, although having lower equipment costs, may drive up unit costs due to low efficiency.
Design costs are charged by professional design companies based on the complexity of the plan. Customized designs or structural innovations require higher fees, while standardized designs have lower costs.
Other expenses include water and electricity installation, door and window installation, and furniture purchases, depending on the decoration standard and furniture configuration. High-end decorations or imported furniture can significantly increase the total cost, while basic decorations have lower costs.
