由于社会化大生产的发展和全寿命周期造价控制的兴起，传统的造价管理模式已经不能符合工程需求。如何针对不同阶段作出相应的设计、优化造价控制以增加项目的价值成为造价控制的最终目标。本文在研究公路建设与LCC适应性和公路工程全寿命周期理论的基础上，得出初步的公路工程造价控制办法：通过对公路工程项目造价控制现状的了解，对工程造价控制进行合理、科学的优化，得出进一步的公路工程造价控制办法；建立公路工程全寿命周期造价控制与优化模型，对各阶段的造价进行量化，分析影响各阶段造价变化的主要因素，进行造价控制的细化，实现公路工程全寿命周期造价控制与优化。
Due to the development of large-scale social production and the rise of life-cycle cost control, the traditional cost management model has been unable to meet the needs of engineering. How to make corresponding designs for different stages and optimize cost control to increase the value of the project has become the ultimate goal of cost control. Based on the study of the adaptability of highway construction and LCC and the theory of the whole life cycle of highway engineering, this paper obtains the preliminary highway engineering cost control method: Through understanding the current status of highway project cost control, rationally and scientifically optimize the project cost control, and obtain further highway engineering cost control measures; Establish the highway engineering life cycle cost control and optimization model, quantify the cost of each stage, analyze the main factors affecting the cost change of each stage, refine the cost control, realize the highway engineering life cycle cost control and optimization.
