设计概算调整幅度大且比较频繁,其中有行政干预、设计深度、施工水平的客观因素,也有调整概算编制中的主观原因。要使调整概算有效地控制工程造价,要在工程实施中从微观控制转变到宏观控制。要在调查研究的基础上,深化改革,改进管理。 The adjustment of design estimates is large and frequent, including objective factors of administrative intervention, design depth and construction level, as well as subjective reasons for adjusting the budget estimates. In order to control the project cost effectively, it is necessary to change from micro-control to macro-control in project implementation. Based on the investigation and study, we must deepen the reform and improve management.
