In terms of cost management, there was a lack of effective cost control measures at first. The procurement cost of curtain wall materials was too high, and there was no sufficient market research and price comparison. There was also material waste during the construction process. At the same time, labor cost management was poor, staff allocation was unreasonable, and there was a phenomenon of idle work. For example, in the construction of glass curtain walls, due to inaccurate calculation of glass specifications, a large amount of glass could not be used after cutting, resulting in material waste. This caused serious cost overruns and greatly compressed the project's profit margin.
In order to strengthen cost management, a cost control team was established. Before purchasing materials, a detailed market survey was conducted, and a curtain wall material supplier with high cost performance was selected through multiple selection and comparison to reduce procurement costs. During the construction process, material use management was strengthened, material consumption quotas were formulated, and the part exceeding the quota was strictly approved. Personnel allocation was optimized, and construction personnel were reasonably arranged according to the progress of the project to avoid idle work. Through these measures, the project cost was effectively controlled, the cost saving rate reached 15 %, and the economic benefits of the curtain wall were improved.
