随着国家建设的快速发展,大型设备的引入,投入水电施工的机械费占工程费的比率有了较大的提高,水电开发商为了尽快发电,最大限度地压缩工期,造成施工期强度过高,引起施工机械的不均衡施工。当前工程造价中的机械费用主要是根据定额计算而得,定额是按平均先进水平均衡施工编制的,而成本核算中的机械费用支出是按施工实际配置的设备计算而得,施工强度峰值过高的不均匀施工必将造成机械费用在造价中与成本核算形成差异,即亏损。这种机械费引起的成本风险应引起足够的重视。
With the rapid development of national construction and the introduction of large-scale equipment, the proportion of mechanical expenses that have been put into hydropower construction in construction costs has been greatly increased. Hydropower developers, in order to generate electricity as soon as possible, minimize the construction period and cause excessive construction intensity , Causing uneven construction machinery construction. The current mechanical cost of the project cost is mainly calculated according to the quota, the quota is based on the average advanced level balanced construction preparation, and cost accounting machinery costs are calculated according to the actual configuration of the equipment calculated, the peak intensity of construction is too high Uneven construction will inevitably cause mechanical costs in the cost and cost accounting differences, that is, loss. This mechanical costs caused by the risk should be paid enough attention.
