2017年5月1日开始,工信部发布的451定额将正式替代上一版本的75定额,用于确定通信建设工程造价。文章深入解读了在无线通信设备安装工程中,75定额和451定额的费用定额、预算定额的主要变化情况,并将一个典型TD-LTE室外站作为案例,对采用451定额后,施工工日及建筑安装工程费的变化情况进行了测算对比。测算结果表明,对于TD-LTE室外站,采用451定额后,施工工日降幅较大,但由于人工费的上涨,建筑安装工程费仍有所上升。
From May 1, 2017, the 451 quota issued by the Ministry of Industry and Information Technology will officially replace the previous quota of 75, which is used to determine the cost of communications construction projects. The article deeply analyzes the main changes of the fixed quota and fixed quota of fixed amount of 75 and fixed amount of 451 in the installation project of wireless communication equipment. Taking a typical TD-LTE outdoor station as an example, Construction and installation costs were measured changes in the comparison. The calculation results show that for the TD-LTE outdoor station, the 451 quota, the construction of a large decline in the construction, but due to rising labor costs, construction and installation costs still increased.
