某施工单位承接了一项外商投资的多层工业厂房项目,合同价为1470万元,其中:基础工程报价400万元,上部结构工程报价720万元,安装工程报价350万元。合同工期为15个月,其中:基础工程工期为4个月,上部结构工程工期为9个月,安装工程工期为5个月,且与上部结构工程施工搭接3个月。
合同规定,提前工期奖为每月30万元,在最后一个月结算时一次性支付。施工单位如果缩短该工程工期,需采用特殊技术措施。经分析,基础工程和上部结构工程可各缩短工期1个月,需分别增加技术措施费25万元和40万元。
合同规定,每月工程款于下月5日前提交付款申请报告,经造价工程师审核后于第3个月末支付。
假定:货款月利率为1%,各分部工程每月完成的工作量相同且能及时收到工程款。
问题:1.若基础工程和上部结构工程各压缩1个月,请画出施工单位相应的加速施工方案的现金流量图。
2.若不考虑资金的时间价值,是否应采用上述加速施工方案为什么
3.若考虑资金的时间价值(以开工日为折现点),是否应采用上述加速施工方案为什么(现值系数见表4-2)
(注:计算结果保留两位小数。)
