问题 问答题

某工程项目业主邀请了三家施工单位参加投标竞争。各投标单位的报价如表7-1所示,施工进度计划安排如表7-2所示。若以工程开工日期为折现点,贷款月利率为1%,并假设各分部工程每月完成的工作量相等,并且能按月及时收到工程款。


1.就甲、乙两家投标单位而言,若不考虑资金时间价值,判断并简要分析业主应优先选择哪家投标单位。
2.就乙、丙两家投标单位而言,若考虑资金时间价值,判断并简要分析业主应优先选择哪家投标单位。
(注:现值系数见表7-3)
3.评标委员会对甲、乙、丙三家投标单位的技术标评审结果如表7-4所列。评标办法规定:各投标单位报价比标底价每下降1%,扣1分,最多扣10分;报价比标底价每增加1%,扣2分,扣分不保底。报价与标底价差额在1%以内时可按比例平均扣减。评标时不考虑资金时间价值,设标底价为2125万元,根据得分最高者中标原则,试确定中标单位。

答案

参考答案:若不考虑资金时间价值,业主应优先选择甲投标单位。
因甲、乙投标单位在相同的施工进度计划安排下甲投标单位总报价低。
2.(1)乙投标单位工程款
基础工程每月工程款A1=210/3=70(万元)
主体工程每月工程款A2=840/5=168(万元)
装饰工程每月工程款A3=1080/4=270(万元)
(2)乙投标单位工程款现值
PV=70(P/A,1%,3)+168(P/A,1%,5)(P/F,1%,3)+270(P/A,1%,4)(P/F,1%,8)
=70×2.9410+168×4.8534×0.9706+270×3.9020×0.9235
=1970.21(万元)
(3)丙投标单位工程款
基础工程每月工程款A1=210/2=105(万元)
主体工程每月工程款A2=840/6=140(万元)
装饰工程每月工程款A3=1080/6=180(万元)
(4)丙投标单位工程款现值
PV=105(F/A,1%,2)+140(P/A,1%,4)(P/F,1%,2)+(140+180)(P/A,1%,2)
(P/F,1%,6)+180(P/A,1%,4)(P/F,1%,8)
=105×1.9704+140×3.9020×0.9803+320×1.9704×0.9420+180×3.9020×0.9235
=1985.00(万元)
或PV=105(P/A,1%,2)+140(P/A,1%;6)(P/F,1%,2)+180(P/A,1%,6)(P/F,1%,6)
=105×1.9704+140×5.7955×0.9803+180×5.7955×0.9420
=1984.96(万元)
(5)业主应优先选择乙投标单位。
因乙投标单位工程款现值较低。
3.(1)计算各投标单位报价得分(表7-8)。
表7-8 投标单位报价得分表

完形填空

When Dan Shaw gets up from the sofa in his home, Cuddles is never far away. When he wants to go outside, he doesn’t take Cuddles out for a walk—Cuddles takes him for a walk. Cuddles is clearly no ordinary family pet. It is a two-foot-high miniature horse and serves as the guiding eyes of Shaw, who is blind.

When Shaw lost his sight, his wife suggested he apply for a guide dog. Shaw, an animal lover, said he couldn’t bear to part with a dog (which usually lives about eight to ten years) and get used to a new one, perhaps several times in his life.

Then Shaw heard of a program about the tiny guide horses. He learned that the horse possess many qualities that that make them an excellent choice for guiding people. They are clean, friendly, smart and have great memories. They can be trained to remain calm in noisy and crowded places. Best of all, they live for 25-25years, which would enable Shaw to have the same guide companion for most or all of his life.

Shaw immediately applied to be and was accepted as the first person to receive a guide horse. The instant he met Cuddles, he knew he was making the right choice. Then he began his training.

Through training, Shaw and Cuddles learned to find way on busy streets, step over curbs(便道沿儿)and find elevator buttons. Cuddles even demonstrated(显示)its ability to step in front of Shaw and block him, to prevent him from walking into a dangerous situation. The little horse also expertly led Shaw through busy shopping malls. They got along without any difficulty. Now Shaw is confident that Cuddles will change his life for the better.
