城市轨交作为支撑城市正常运行的大动脉,近年来发展迅速。它能将城市各个区域联系起来,拉近区域之间的距离;能显著提高城市交通运输能力,大大缓解并改善城市交通拥堵的状况。在整个轨交工程项目中,机电专业投资占总投资额的比例日趋上升,对总体造价的直接影响越来越受到人们的重视。在预结算过程中,采用合同对比、单价分析等方法进行全过程造价控制,对机电专业计量计价严格把控,使工程以最少的投资额达到最好的效果。 As a major artery that supports the normal operation of urban areas, urban rail transit has developed rapidly in recent years. It can link up various regions of the city and narrow the distance between regions. It can significantly improve the urban transport capacity and greatly ease and improve the traffic congestion in the city. In the entire rail transit project, the proportion of electromechanical investment in the total investment is on the rise, and the direct impact on the overall cost has drawn more and more attention. In the pre-settlement process, the whole process of contract control, unit price analysis and other methods of cost control, the mechanical and electrical professional measurement and control strictly controlled, so that the project with the least amount of investment to achieve the best results.
