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:

(1)合同工期160日,承包人编制的初始网络进度计划,如图1所示。

由于施工工艺要求,该计划中C、E、I 3项工作施工需使用同一台运输机械;B、D、H3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。

(2)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 9项工作的人工工日消耗量分别为:100、400、400、300、200、60、60、90、100个工日。

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。

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

[问题]

在因设计变更使工作E增加工程量的事件中,承包商除在工作E上可以索赔费用外,是否还可以索赔其他费用如果有可以索赔的其他费用,请分项列式计算可以索赔的费用,如果没有,请说明原因。(计算结果均保留2位小数)

答案

参考答案:

还可以索赔其他费用,这些费用包括: (1)H工作费用索赔。 ①因为H工作有10天总时差,所以,人员窝工和吊装机械闲置时间为:20-10=10天 ②每天窝工人工数为:90/30=3工日/天 ③索赔费用为:3×10×25+10×500=5750元 (2)工作费用索赔。 ①人员窝工时间为20天。 ②每天窝工人数为:1000/50=20工日/天 ③索赔费用为:20×20×25=10 000元 [解题思路点拨] 本题考查的知识点是建设项目施工阶段进度计划的编制以及合同管理中价款管理的相关内容。问题考查网络计划在资源限定情况下的调整。问题2考查关键线路和总工期的确定。问题3和问题4考查索赔费用的计算。费用的索赔是和工期延误紧密联系在一起的,这就要求正确辨别哪些延误是在关键线路上的,延长时间是否超过了总时差,闲置时间为超过总时差的时间。

Most plants can make their own food from sunlight, (1) some have discovered that stealing is an easier way to live. Thousands of plant species get by (2) photosynthesizing, and over 400 of these species seem to live by pilfering sugars from an underground (3) of fungi(真菌). But in (4) a handful of these plants has this modus operandi been traced to a relatively obscure fungus. To find out how (5) are (6) , mycologist Martin Bidartondo of the University of California at Berkeley and his team looked in their roots. What they found were (7) of a common type of fungus, so (8) that it is found in nearly 70 percent of all plants. The presence of this common fungus in these plants not only (9) at how they survive, says Bidartondo, but also suggests that many ordinary plants might prosper from a little looting, too.

Plants have (10) relations to get what they need to survive. Normal, (11) plants can make their own carbohydrates through photosynthesis, but they still need minerals. Most plants have (12) a symbiotic relationship with a (13) network of what are called my corrhizal fungi, which lies beneath the forest (14) . The fungi help green plants absorb minerals through their roots, and (15) , the plants normally (16) the fungi with sugars, or carbon with a number of plants sharing the same fungal web, it was perhaps (17) that a few cheaters—dubbed epiparasites—would evolve to beat the system. (18) , these plants reversed the flow of carbon, (19) it into their roots from the fungi (20) releasing it as "payment.\
