【摘要】：随着政府对公共基础设施投入的不断扩大，一方面公路工程投资不断增长，另一方面公路工程成本却也逐年上涨，导致施工企业利润空间压缩，利润率不断下降，施工成本控制显得尤为重要。但施工企业对于施工成本的控制现状却不容乐观，成本控制意识相对较淡薄，成本控制过程控制技术和方法较落后，且往往集中于事前控制，事中和事后控制环节薄弱，导致实际成本屡超计划成本，成本控制的效果不理想。本文基于现有的公路施工成本控制理论，结合成本信息管理在成本控制中的重要地位，针对实际工程中成本信息收集及处理方面存在的问题，探索适用于公路项目的信息管理体系。论文对施工成本信息进行了梳理，并借鉴Omniclass分类编码体系，建立适用于公路的Hc-class成本分类体系，，对成本信息按照一定的规则进行归类和编码，然后通过Hc-class分类表格维度的扩展及相互之间的联系，对直接成本信息进行处理，并对成本关联信息—供应商信息和合同信息进行管理。进而对Hc-class的一般运用进行阐述，即通过编码之间的相互关系及运算，将与成本关联信息进行集成管理，并列举其在公路工程中产值收集、成本分析及成本预测方面的应用。最后结合工程实际案例，论述Hc-class在项目产值收集、施工成本对比分析及纠偏、施工成本预测方面的功能，从而达到施工成本动态控制的目的。
[Abstract]:With the continuous expansion of government investment in public infrastructure, on the one hand, the investment of highway engineering is increasing, on the other hand, the cost of highway engineering is also rising year by year, which leads to the reduction of profit space and the decline of profit margin of construction enterprises, so it is particularly important to control the construction cost. However, the construction enterprises are not optimistic about the present situation of construction cost control, the consciousness of cost control is relatively weak, the cost control process control technology and method are backward, and often focus on the control in advance and after the event, which leads to the actual cost repeatedly exceeding the planned cost and the effect of cost control is not ideal. Based on the existing highway construction cost control theory, combined with the important position of cost information management in cost control, aiming at the problems existing in the collection and processing of cost information in practical engineering, this paper explores the information management system suitable for highway project. This paper combs the construction cost information, and uses Omniclass classification and coding system for reference, establishes the Hc-class cost classification system suitable for highway, classifies and encodes the cost information according to certain rules, and then processes the direct cost information through the expansion of Hc-class classification table dimension and the relationship between them, and manages the cost association information-supplier information and contract information. Furthermore, the general application of Hc-class is described, that is, through the relationship and operation between codes, the information related to cost will be integrated and managed, and its application in output value collection, cost analysis and cost forecasting in highway engineering is listed. Finally, combined with the actual engineering case, this paper discusses the functions of Hc-class in the collection of project output value, the comparative analysis of construction cost and the prediction of construction cost, so as to achieve the purpose of dynamic control of construction cost.
