背景资料

某中型水库除险加固工程主要建设内容有:砌石护坡拆除、砌石护坡重建、土方填筑(坝体加高培厚)、深层搅拌桩渗墙、坝顶沥青道路、混凝土防浪墙和管理房等。计划工期9个月(每月按30天计)。合同约定:①合同中关键工作的结算工程量超过原招标工程量15%的部分所造成的延期由发包人承担责任;②工期提前的奖励标准为10000元/天,逾期完工违约金为10000元/天。

施工中发生如下事件:

事件1:为满足工期要求,采取分段流水作业,其逻辑关系如下表:

1

项目部技术人员编制的初始网络计划如下:

2

项目部在审核初始网络计划时,发现逻辑关系有错并将其改正。

事件2:项目部在开工后第85天末组织进度检查,F、H、E、J工作累计完成工程量分别为400m3、600┫、20000m3、125┫(假定 工作均衡施工)。

事件3:由于设计变更,K工作的实际完成时间为33天,K工作的结算工程量为292m3.

除发生上述事件外,施工中其他工作均按计划进行。

问题:

指出事件1中初始网络计划逻辑关系的错误之处。

依据正确的网络计划,确定计划工期(含施工准备)和关键线路。

根据事件2的结果,说明进度检查时F、H、E、J工作的逻辑状况(按“……工作已完成……天工程量”的方式陈述)。指出哪些工作的延误对工期有影响及影响天数。

事件3中,施工单位是否有权提出延长工期的要求?并说明理由。

综合上述事件,该工程实际工期是多少天?承包人可因工期提前得到奖励或逾期完工支付违约金为多少?

纠错
正确答案:

错误之处:E改正的紧前工作应为C、D工作(1分),而初始网络计划中,E工作的紧前工作只有C工作(1分)。

在节点④、⑤之间缺少一项虚工作(2分)。

或E工作与C、D工作之间的逻辑关系--(2分)。

计划工期270天(1分)

关键线路:A-B-D-H-I-K-L-M(2分)

F工作已完成4天工程量(1分),H工作已完成8天工程量(1分),E工作已完成10天工程量(1分),I工作已完成25天工程量(1分),H、J工作拖延对工期有影响(2分),H工作的延误对工作影响3天(1分),J工作的延误对工期影响5天(1分)。

有权(1分),依据合同承包人对K工作结算工程量超过276m3(240*115%)(1分)部分所造成的工程延误可以提出延期要求,可提出2天的延期要求(1分)。

该工程的实际工期为278天(270+5+3)(2分)因逾期完工支付违约金为60000元[10000*(278-270-2)])

Dear Sir/Madam, I am pleased to write a letter of recommendation on behalf of Sand River and its CEO, Mrs. Jane King. I am very familiar with the company. My next book deals with it in detail, which is to be published in autumn of 2018. I am also familiar with European consumer. As a Dutch citizen, I have lived in Europe for 46 years and studied European consumer behavior for decades.I believe that Sand River offers something unique to the European market. It has established long-term supply relations with herdsman ( 牧民) families and owns advanced German machinery. Thus it combines natural resources with modern manufacturing techniques. But equally important, Sand River works with modern fashion designers to create truly contemporary and appealing designs. The result is a newly-established cashmere ( 羊绒) brand that appeals to a target group of high-income women. I met Mrs. King the first time in 2013. Since then, we have met several times and talked about Sand River's philosophy, strategy, and appeal to both Chinese and international consumers. I was struck by her deep knowledge about knitting (针织) technology, her enthusiasm for the brand, and her deep understanding of the cashmere shopper. I regard her as a "woman of her word." To summarize, I believe Sand River products deserve a place in luxurious European department stores and Mrs. King is a reliable partner. If you have any questions, please do not hesitate to contact me. Sincerely, Joan Smith 36、 Joan Smith wrote the recommendation letter on behalf of ______.
