| dc.description.abstract | Municipal engineering projects are crucial components of urban construction, and their cost management directly affects the quality and efficiency of urban development. As the foundation of total cost formation, unit price is a key factor in cost control. To understand the current situation and problems of municipal engineering cost management in A certain municipality directly under the central government, this study selected 13 cases of road engineering, sidewalk engineering, and street lamp engineering in A certain municipality directly under the central government and conducted K-Means clustering and cross-comparison analysis on their unit area cost.The study found significant differences in unit price levels among various specialties of municipal engineering projects in A certain municipality directly under the central government. Road engineering and sidewalk engineering were generally similar, while street lamp engineering showed extreme unit price variations. This may be related to the characteristics of different specialties in design standardization and construction customization. Moreover, the degree of unit price variation within each specialty also differed. Road engineering had the smallest internal difference, followed by sidewalk engineering, and street lamp engineering had the largest. This requires us to adapt to local conditions and take targeted approaches when preparing budgets and controlling costs.Further cross-comparison analysis indicated that the unit prices of most projects were mainly concentrated at a moderate level, while cases with low and high unit prices were relatively few. This suggests that in cost management practice, we should focus on and analyze cases that deviate significantly from the average level to identify potential problems and optimization opportunities. However, it should also be recognized that unit price alone cannot fully reflect the rationality of project cost. It needs to be systematically analyzed within the context of specific case design conditions, construction requirements, and market conditions.In summary, through the clustering and cross-comparison of unit price levels in A certain municipality directly under the central government′s municipal engineering projects, this study provides a new perspective for diagnosing and optimizing cost management. We recommend that owners, design, and construction units should strengthen cost management throughout the project lifecycle by enhancing design optimization, construction organization, bidding control, contract management, and other aspects while ensuring project quality and safety to continuously improve investment efficiency. In the future, unit price comparison analysis can be further combined with management data of changes, measurements, and acceptances in various specialized projects to provide a more solid basis for refined project cost control and promote the overall advancement of municipal engineering management in A certain municipality directly under the central government. | en_US |
