在国家电网公司大力推行工程量管理的背景下，如何进行有效的过程造价控制是值得研究的课题。在以往施工图预算概念的基础上，提出施工图管理预算，通过对施工图量差预算的深入分析，加强工程实施过程中工程量、物资量及造价的实时监控，可提高工程建设过程管理水平的目的。案例分析表明，施工图管理预算的应用效果显著、可操作性强、应用价值大，可为输变电工程管理提供决策支持。

It is worthy to study the effective cost control since the State Grid Corporation has vigorously implemented the engineering volume management. Based on the previous concept of constructing budget drawings, the concept of constructing drawings management budget has been proposed in this paper. By deep analyzing the construction drawings budget of amount difference, the real-time monitoring of the amount of construction, materials and costs in the construction had been enhanced in order to improve the management level in engineering. The case study shows that the application effect of the construction drawings management budget is significantly, and it is strongly operational and applicable, which can provide a decision-making support for the power transmission project management.
