变更索赔成功案例-某工程基坑异常排水变更索赔报告

#某工程基坑异常渗水抽排水变更索赔报告一、编制原则1、依据合同原则2、实事求是原则二、编制依据1、《西藏某河某水电站左副坝、厂房、泄洪闸土建及金属结构安装工程招标文件》；2、《西藏某河某水电站左副坝、厂房、泄洪闸土建及金属结构安装工程投标文件》；3、《西藏某河某水电站左副坝、厂房、泄洪闸土建及金属结构安装工程施工合同》（合同编号XZDB-SG-2012-47）（以下简称《施工合同》）；4、工程变更/索赔立项审核（批）表（变更编号：SP01）；5、《某水电站基坑排水泵流量测量报告》（三方鉴证）；6、基坑排水施工方案及监理、业主批复报告单。三、变更补偿项目基本情况本工程投标文件中关于施工排水描述为“最大排水量为157.8m3/h”，施工合同中第二章补充协议第10项规定“基坑经常性渗漏抽排水不超过2000m3/h时，所发生的所有费用已包含在合同相应总价中”。实际施工抽排水最大时达到11525.38m3/h，远大于投标施组和合同文件规定的抽排量，造成承包商施工成本大幅增加，据此对超过2000m3/h的费用进行计算上报。四、费用计算（一）费用计算依据本变更补偿依据专用合同条款“15.4变更的估价原则15.4.3目补充：上述成本加利润计算方法为：成本构成中数量按照《水电建筑工程预算定额》（2004版）的人工、材料、机械台时（班）定额量，并按投标报价较定额消耗水平的调整幅度进行调整后的数量，单价采用投标报价文件中所填报的人工预算单价、材料预算价格、机械台时（班）费单价，利润取费费率标准按照投标利润取费费率。”为依据进行费用计算。（二）费用计算思路根据合同文件要求，基坑抽排水2000m3/h以内的费用由承包商承担，则超过2000m3/h的由发包人承担，且目前基坑排水尚在进行，为便于对已发生抽排水费用计算和后期抽排水费用计算，按照抽排水综合单价法进行费用计算，并用实际成本法进行佐证的方式进行抽排水费用计算。（三）费用计算基础数据本变更工程采用与投标定额相一致的［2004］《水电建筑工程预算定额》和《水电建筑工程施工机械台班费定额》。1）人工费预算价格：高级熟练工13.25元/工时，熟练工9.78元/工时，半熟练工7.61元/工时，普工6.25元/工时。2）材料预算价格和机械台时费，按照合同中价格执行，合同中没有的相应价格参照市场价格执行。3）取费费率按照《施工合同》文件规定取费费率。其他工程：其它直接费5.10%，间接费：7.26%，利润：3.0%，税金：3.48%。4）高原系数，机械设备取1.35。（四）费用计算1、基本水价计算根据定额，按照“水泵组时总费用:（水泵额定容量之和X能量利用系数）:（1-排水损耗率）+排水设施维修摊销费”公式计算基本水价为0.657元/m3。具体计算见附表一《基坑排水基本水价计算表》。其中“水泵组时总费用”、“水泵额定容量之和”参数采用取每年3、6、9、12月份抽排水时段作为典型时段计算取其均值，具有广泛的代表性；“能量利用系数”采用经三方认证的西藏自治区水温资源勘测局测定的系数64.15%；“排水损耗率”根据定额取10%；“排水设施维修摊销费”根据定额取0.04。具体参数计算见附表二、附表三、附表四。2、综合水价计算根据取费标准，计算综合水价为0.7894元/m3。具体计算见附表五《基坑排水综合单价分析表》。3、总费用计算根据经三方签字确认的水泵抽排水台时统计，自2012年4月（2012年3月抽排量小于2000m3/h,不予统计）至2014年7月31日抽排水量为182618406.92m3，抽排水总费用为144159767.38元。其中2000m3/h抽排水量为40992000m3,抽排水费用为32359263.69元。因此自工程开工至2014年7月31日应补偿的抽排水费用为111800503.69元。具体见附表六《某水电站基坑抽排水费用计算总表（截至时间2014年7月31日）》。五、辅助佐证资料根据现场实际发生的抽排水成本统计，抽排水直接成本为101611539元。考虑间接费、利润、税金等综合取费15%，则实际成本为116853269.85元。具体见附表七《基坑抽排水成本统计表》。六、附表附件：单价法计算附表七、附件1、工程变更/索赔立项审核（批）表（变更编号XZDB-SG-2012-47）；2、某水电站基坑排水泵流量测量的报告（水资源勘测局）、基坑流量计算书；3、基坑抽水设备运行记录表；4、相关工作联系函5、基坑排水施工方案及批复意见6、基坑排水相关图片资料。编制人：某水电站工程项目部日期： 2014年9月8日
