问题 问答题 案例分析题

某机电安装工程公司承接某汽车厂重型压力机车间机电设备安装工程,工程内容包括:设备监造,压机的就位安装、压力管道安装、电气工程、自动控制工程和单机试运行等。其中压机最高22.5m,单件最重为105吨。合同工期为4个月。合同约定,工期每推迟一天罚10000元,提前一天奖励5000元。

对压力管道的安装,机电安装工程公司项目部在安装前按规定履行了书面告知手续。

该公司项目部对承接工程进行分析,工程重点是压机吊装就位,为此,制定了两套吊装方案:

第一套方案:采用桅杆式起重机吊装。经测算施工时间需要50天,劳动力安排日平均为30人,参照相关规定计算人工日平均工资50元,机械台班费及新购置钢丝绳和索具费用共20万元,其他费用2.5万元。

第二套方案:采用两台1OO吨履带式起重机抬吊。吊车需要租赁,租赁费用1万元/台班,但不发生购置钢丝绳和索具费和其他机械台班费。经测算,现场共需14天,与第一套方案相比人工费可降低70%,其他费用可降低30%。该项目部合理选择了吊装方案,注重安全管理,合理调度,加强了施工阶段的成本控制,尤其对压机吊装成本费用的控制。吊装部队发挥了积极性,如期完成任务,为后面工序创造了良好条件,使该工程项目提前8天完成了施工任务。

分别计算压机吊装两套方案的成本费用。

答案

参考答案:

计算每套压机吊装方案的成本费用

(1)桅杆式起重机吊装方案:

人工费:人日平均工资×施工天数×日平均劳动力安排人数=50×50×30=75000元;

机械台班费及新购置钢丝绳和索具费用:200000元;

其他费用:25000元;

合计:75000+200000+25000=300000元

(2)履带起重机方案吊装成本费用:

台班费:10000×14×2=280000元

人工费:75000×(1-70%)=22500元

其他费用:25000×(1-30%)=17500元

合计:280000+22500+17500=320000元
