提高自控仪表单位工程概算正确性的途径

Ways to Increase Correctness in Rough Estimate of Unit Project of Automatic-control Instrument

技术与经济相结合是合理确定和有效控制工程造价的最有效途径。自控仪表工程具有专业技术性强、种类繁多、发展迅速、更新换代快等特点，技术与经济分离的现象严重，致使自控仪表单位工程概算准确性不高。工程造价管理人员必需努力学习专业技术知识才能提高工程概算的正确性。

The combination of technology with economy is most effective way to reasonably determine and well control the engineering cost. Automatic-control instrument engineering has such characteristics as obvious technicality, numerous varieties, fast development and renewal, etc. The phenomenon of separating technology from economy is quite serious. As a result, the correctness in rough estimate of unit project of automatic-control instrument engineering is not high. For increasing its correctness,the engineering cost operating personnel must learn hard the specialized technical knowledge.
