问题 问答题

某大型工业项目的主厂房工程,发包人通过公开招标选定了承包人,并依据招标文件和投标文件,与承包人签订了施工合同。合同中部分内容如下:

合同工期160天,承包人编制的初始网络进度计划,如图5-1所示。

由于施工工艺要求,该计划中C、E、I三项工作施工需使用同一台运输机械;B、D、H三项工作施工需使用同一台吊装机械。上述工作由于施工机械的限制只能按顺序施工,不能同时平行进行。

(1) 承包人在投标报价中填报的部分相关内容如下:

①完成A、B、C、D、E、F、G、H、I九项工作的人工工日消耗量分别为:100、400、 400、300、200、60、60、90、1000(工日)。

②工人的日工资单价为50元/工日,运输机械台班单价为2400元/台班,吊装机械台班单价为1200元/台班。

③分项工程项目和措施项目均采用以直接费为计算基础的工料单价法,其中的间接费费率为18%;利润率为7%;税金按相关规定计算。施工企业所在地为县城。

(2) 合同中规定:人员窝工费补偿为25元/工日,运输机械折旧费为1000元/台班,吊装机械折旧费为500元/台班。

在施工过程中,由于设计变更使工作E增加了工程量,作业时间延长了20天,增加用工100个工日,增加材料费2.5万元,增加机械台班20个,相应的措施费增加1.2万元。同时,E、H、I的工人分别属于不同工种,H、I工作分别推迟20天。

对承包人的初始网络进度计划进行调整,以满足施工工艺和施工机械对施工作业顺序的制约要求。

答案

参考答案:

对初始网络进度计划进行调整,结果如图5-7所示。

单项选择题 A1/A2型题
单项选择题

A deal is a deal—except, apparently, when Entergy is involved. The company, a major energy supplier in New England, provoked justified outrage in Vermont last week when it announced it was reneging on a longstanding commitment to abide by the state’s strict nuclear regulations.

Instead, the company has done precisely what it had long promised it would not challenge the constitutionality of Vermont’s rules in the federal court, as part of a desperate effort to keep its Vermont Yankee nuclear power plant running. It’s a stunning move.

The conflict has been surfacing since 2002, when the corporation bought Vermont’s only nuclear power plant, an aging reactor in Vernon. As a condition of receiving state approval for the sale, the company agreed to seek permission from state regulators to operate past 2012. In 2006, the state went a step further, requiring that any extension of the plant’s license be subject to Vermont legislature’s approval. Then, too, the company went along.

Either Entergy never really intended to live by those commitments, or it simply didn’t foresee what would happen next. A string of accidents, including the partial collapse of a cooling tower in 207 and the discovery of an underground pipe system leakage, raised serious questions about both Vermont Yankee’s safety and Entergy’s management—especially after the company made misleading statements about the pipe. Enraged by Entergy’s behavior, the Vermont Senate voted 26 to 4 last year against allowing an extension.

Now the company is suddenly claiming that the 2002 agreement is invalid because of the 2006 legislation, and that only the federal government has regulatory power over nuclear issues. The legal issues in the case are obscure: whereas the Supreme Court has ruled that states do have some regulatory authority over nuclear power, legal scholars say that Vermont case will offer a precedent-setting test of how far those powers extend. Certainly, there are valid concerns about the patchwork regulations that could result if every state sets its own rules. But had Entergy kept its word, that debate would be beside the point.

The company seems to have concluded that its reputation in Vermont is already so damaged that it has noting left to lose by going to war with the state. But there should be consequences. Permission to run a nuclear plant is a public trust. Entergy runs 11 other reactors in the United States, including Pilgrim Nuclear station in Plymouth. Pledging to run Pilgrim safely, the company has applied for federal permission to keep it open for another 20 years. But as the Nuclear Regulatory Commission (NRC) reviews the company’s application, it should keep in mind what promises from Entergy are worth.

By entering into the 2002 agreement, Entergy intended to()

A. obtain protection from Vermont regulators

B. seek favor from the federal legislature

C. acquire an extension of its business license

D. get permission to purchase a power plant
