一、概述国外水电工程常用的单价估算方法有两种:一是单价法,二是大型工程施工估价法。单价法是参考已建工程所积累的单价资料,进行工程类比,近似地采用已建工程的单价作为估价工程的单价。这种方法十分简单,但不准确,多用于以人力为主的部份工程项目和临建工程估价。大型工程施工估价法则不采用统一定额,而是针对工程的实际情况,选择先进的施工方法,严格按照工作面的施工组织形式配备施工设备和劳力,准确地计算完成一定工程量所需的劳力工时、设备台时和材料数量,从而计算工程项目的单价。这种方法较复杂,但准
First, an overview of foreign hydropower projects common unit price estimation methods are two: First, the unit price method, and second, large-scale construction project valuation method. The unit price method refers to the unit price data accumulated by the already-built projects, performs engineering analogy, and approximates the unit price of the built project as the unit price of the project. This method is very simple, but not accurate, mostly used for human-based part of the project and the construction project valuation. Large construction project valuation rules do not use a uniform quota, but for the actual situation of the project, select the advanced construction methods, in strict accordance with the face of the construction organization form equipped with construction equipment and labor to accurately calculate the amount of labor required to complete a certain amount of labor , Equipment time and the number of materials to calculate the unit price of the project. This method is more complicated, but accurate
