由于水利水电工程的特殊性,在施工中经常会出现因非承包商原因导致的工效降低问题。如何计算工效降低索赔款额,目前并无统一的规则,但其方法很多,其中时段工效计价法较为合理,操作也较为方便。该方法的索赔款额主要由选定时段中少完成工程量和窝工单价相乘得出。少完成工程量是指实际完成工程量与已批准计划工程量相比减少量。窝工单价由人员窝工费、设备停置费和管理费组成。
Due to the particularity of water conservancy and hydropower projects, there is often a problem of work efficiency reduction due to non-contractors in construction. There are currently no uniform rules on how to calculate the work efficiency and reduce the amount of claims. However, there are many ways in which the time-based valuation method is more reasonable and the operation is more convenient. The claim amount for this method is mainly obtained by multiplying the less completed project volume and labor unit price in the selected period. Less completed project volume refers to the actual completed project volume compared with the approved project volume reduction. Wo labor price by the staff nest fee, equipment and management fees to stay.
