摘要
文中针对装配式和现浇式两种主体工程施工方法成本进行分析,主要研究了施工成本的构成和人工费、材料费和机械费的差异。研究结果表明,相较于传统现浇项目,装配式住宅的人工费呈现相对增长的趋势,多数项目的单位面积人工费高出现浇项目,反映出对熟练技术工人需求的增加。在材料费方面,由于装配式住宅对材料使用等级的提升,单位面积材料费普遍高于现浇项目,预制构件费用在材料费中占据较大比重。尽管装配式住宅在某些施工环节上采用了更高机械化程度的施工方式,但现浇项目的单位面积机械费用仍高出装配式项目约10%。该结论可为优化装配式住宅施工成本控制提供参考。
This article analyzes the cost of two main construction methods,prefabricated and cast-in-place,and mainly studies the composi-tion of construction costs and the differences in labor,material,and machinery costs.The research results indicate that compared to traditional cast-in-place projects,the labor cost of prefabricated housing shows a relatively increasing trend.The high labor cost per unit area in most projects reflects an increasing demand for skilled and skilled workers.In terms of material costs,due to the improvement of material usage lev-els in prefabricated housing,the material cost per unit area is generally higher than that of cast-in-place projects,and prefabricated compo-nents account for a large proportion of material costs.Although prefabricated housing adopts a higher degree of mechanization in certain con-struction stages,the unit area machinery cost of cast-in-place projects is still about 10%higher than that of prefabricated projects.The re-search conclusion provides a reference basis for optimizing the cost control of prefabricated residential construction.
