在施工过程中,施工单位向监理工程师提出如下费用应由业主支付。

1,职工教育经费:因该项目的汽轮机是国外进口的设备,在安装前,需要对安装操作的职工进行培训,培训经费2万元。

2.研究试验费:本项目中铁路专用线的一座跨公路预应力拱桥的模型破坏性试验费8万元,改进混凝土泵送工艺试验费3万元,合计11万元。

3.临时设施费:为修变电站搭建的民工临时用房5间和为业主搭建的临时办公室3间,分别为2万元和1万元,合计3万元。

4.施工机械迁移费:施工吊装机械从另一工地调入本工地的费用1万元。

5.施工降效费:

(1)根据施工组织设计,部分项目安排在雨季施工,由于采取防雨措施,增加费用2万元。

(2)由于业主委托的另一家施工单位进行场区道路施工,影响了本施工单位正常的混凝土浇筑运输作业,监理工程师已审批了原计划和降效增加的工日及机械台班的数量。资料如下。

受影响部分的工程原计划用工2200工日,计划支出40元/工日,原计划机械台班360台班,综合台班单价为180元/台班,受施工干扰后完成该部分工程实际用工2800工日,实际支出45元/工日,实际用机械台班410台班,实际支出200元/台班。1. [问题]

1.试分析以上各项费用业主应不应支付为什么?

2.第5条(2)中提出的降效支付要求,工费和机械使用费各应补偿多少?

3.监理工程师绘制的S形曲线如图7-1所示。若该工作进行到第5个月底和第10个月底时,试分析:

图7-1 S形曲线图

(1)合同执行到第5个月底时的进度偏差和投资偏差;

(2)合同执行到第10个月底时的进度偏差和投资偏差。

答案

参考答案:

在各项费用中:

(1)职工教育经费不应支付,该费用已包含在合同价中[或该费用已计人建安工程费的间接费 (或管理费)中]。

(2)模型破坏性试验费用应支付,该费用未包含在合同价中[或该费用属业主应支付的研究试验费(或业主的费用)]。

混凝土泵送工艺改进试验费不应支付,该费用已包含在合同价中(或该费用已计入建安工程费的其他直接费中)。

(3)为民工搭建的用房费用不应支付,该费用已包含在合同价中(或该费用已计人建安工程费的现场经费中)。

为业主搭建的用房费用应支付,该费用未包含在合同价中(或该费用属业主应支付的临时设施费)。

(4)施工机械迁移费不应支付,该费用已包含在合同价中(或该费用属建安工程费中的机械使用费)。

(5)降效费(1);不应支付,属施工单位责任(或该费用已计人建安工程费的其他直接费中);降效费(2)应支付,该费用属业主应给予补偿的费用。

2.工费补偿(2800-2200)×40=2400(元);机械台班费补偿(410-360)×180=9000 (元)。

3.进度偏差和投资偏差:

(1)第5个月底进度无偏差(或进度偏差为零),投资偏差为500万元。

(2)第10个月底进度偏差为落后1.5个月(或1500万元),投资偏差为超过500万元。
