在高速铁路工程项目建设中,甲供、甲控材料费用占施工产值比例较高,约占建筑工程造价的31%(不含标段梁厂预制)。桥梁、隧道工程长度所占比例大的山区铁路及建设标准要求更高的客运专线铁路,材料费用所占比例更高。因此加强对甲供、甲控材料的管理应引起高度重视。 In the construction of high-speed railway projects, the cost of A and A materials accounts for a large proportion of the construction output value, accounting for about 31% of the construction cost (excluding the prefabrication of the segment beam factory). Bridges and tunnels with a large proportion of the length of the mountainous railway and the construction standards require a higher proportion of passenger dedicated railway lines with higher material costs. Therefore, to strengthen the management of a-controlled and a-controlled materials should be given high priority.
