[背景]

某工程建设项目,甲、乙双方签订了施工合同,施工进度计划已达成一致意见(图a)。合同规定由于甲方责任造成施工窝工时,窝工费按原人工费、机械台班费的60%计算。

E工序人工30人/天,吊车一台/天

F工序人工35人/天,搅拌机一台/天

G工序人工15人/天,卷扬机一台/天

H工序人工35人/天,搅拌机一台/天

工工序人工20人/天,无施工机械

在施工过程中出现以下事件:

1.因业主不能及时供应材料,使E延误3天,G延误2天,H延误3天;

2.因施工机械故障使E延误2天,G延误2天;

3.因设计变更,使F延误3天;

4.因外部供电故障,使F延误1天,I延误l天。

根据双方商定,人工费定额为28元/日,E工序使用吊车台班费为240元/台班,F工序使用搅拌机台班费为70元/台班,G工序卷扬机台班费为55元/台班,H工序搅拌机台班费为70元/台班,间接费率为 16%,利润率为5%。根据上述约定乙方提出工期补偿17天和费用索赔18525.78元的要求。

(问题)

1.确定该工程项目的施工进度关键线路和F、G、H工序的总时差。

2.乙方上述要求是否合理?

3.经甲方代表认定的索赔工期和费用补偿应为多少?

答案

参考答案:

1.用标注法确定关键线路(见图b)

关键线路刀:

M—A—E—H—L—J—N

F工序TF=5,G工序TF=19,H工序TF=0。

2.乙方代表提出要求不合理。

3.事件1、3、4均属于甲方责任,事件2为乙方责任。F、G工序为非关键工序延误时间未超过其总时差,不影响工期,故不进行工期补偿。E、H、I为关键工序,延误影响总工期。延误时间E工序补偿3天, H工序补偿3天,I工序补偿1天,共计补偿工期7天。

经济索赔:

(1)机械窝工费(闲置费):

E工作:3×240×60%=432(元)

F工作:(3+1)×70×60%=168(元)

G工作:2×55×60%=66(元)

H工作:3×70×60%=126(元)

合计:792(元)

(2)人工窝工费:

E工作:3×30×28×60%=1512(元)

F工作:4×35×28×60%=2352(元)

G工作:2×15×28×60%=504(元)

H工作:3×35×28×60%=1764(元)

I工作:1×20×28×60%=336(元)

合计:6468(元)

(3)因属暂时停工,间接费损失不予补偿。

(4)因属暂时停工,利润损失不予补偿。

结论:经济补偿合计792+6468=7260(元)

Recipients(接受者)of this year's Annenberg scholarships were announced on June 19. Brittany Blythe was one of them.

In seventh grade,Brittany Blythe dreamed of being a cheerleader(啦啦队队员). Her school’s coaches were less than enthusiastic. “They said. ‘I don't know how you’ll be able to do it’. ”she recalls. “‘You won’t be able to do it’.”

But Brittany,now a junior at Strath Haven High School near Philadelphia,refused to give up. And when the junior school cheerleaders won a tournament last year, she was right there,dancing and cheering with the rest of the team.

Not bad for someone whose legs were cut off below the knee when she was two years old.

Brittany,18,was born without shinbones(胫骨)—“just blood and muscle tissue,”as she puts it. When she tried to walk, her legs twisted.    

After the operation, she adapted quickly. “From day one,I basically jumped up and wanted to do everything,’’ she says. Prostheses(假肢)allowed her to move around upright. But too slowly to keep up with her friends. Brittany’s solution was to take the legs off and walk on her knees something she still does when safety and comfort permit.

She has been rarely discouraged. Other children laughed at her through the years,especially in junior high school,but she says the challenge only made her stronger. Now she’s trying to convince her coaches to let her remove the prostheses and be a flyer. The cheerleader who's thrown in the air and caught by her teammates.

Brittany doesn’t think her problems put her at a disadvantage. “My disability was the first thing I had to get through., and that’s going to prepare me for the future. ”she says. “It’s all just a test:If someone throws you a difficult problem,what are you going to do?”
