问题 问答题

【背景资料】
某建筑公司于2002年4月16日与某厂签订了修建建筑面积为3000m2工业厂房的施工合同。建筑公司编制的施工方案和进度计划已获监理工程师批准。该工程的基坑开挖土方量为4500m3,假设直接费单价为4.2元/m3,综合费率为直接费的20%。该基坑施工方案规定:土方工程采用租赁一台斗容量为1m3的反铲挖掘机施工,租赁费为450元/台班。合同约定5月11日开工,5月20日完工。在实际施工中发生了如下几起事件。
事件一:因租赁的挖掘机大修,晚开工2天,造成人员窝工10工日。
事件二:施工过程中,因遇软土层,接到监理工程师5月15日停工的指令.进行地质复查,配合用工15个工日。
事件三:5月19日接到监理工程师发出的5月20日复工令,同时收到基坑开挖深度加深2m的设计变更通知单,由此增加土方开挖量900m3
事件四:5月20日~5月22日,因下季节性大雨迫使基坑开挖暂停,造成人员窝工10个工日,5月23日恢复挖掘工作,最终基坑于5月29日施工完毕。
【问题】1. 1.建筑公司对上述哪些事件可以向厂方要求索赔,哪些事件不可以要求索赔。并说明原因。
2.每起事件工期索赔各是多少天(假定事件均在关键线路上)总计工期索赔是多少天
3.如人工费单价为23元/工日,因增加用工所需的管理费为增加人工费的30%,则合理的费用索赔总额是多少
4.建筑公司应向厂方提供的索赔文件有哪些

答案

参考答案:1.事件一索赔不成立。因该事件发生原因属承包商自身的责任。
事件二索赔成立。因该施工条件的变化不是承包商引起的。
事件三索赔成立。因该事件是设计变更引起的索赔。
事件四索赔不成立。因该事件是一个有经验的承包商可以合理预见的。
2.事件二索赔工期5天。
事件三因增加工程量引起的工期延长,按批准的施工进度计划计算。原计划每天完成工程量:4500/10m3=450m3
现增加工程量900m3,因此应增加工期为900/450天=2天。总计工期索赔:(5+2)天=7天
3.事件二人工费15×23元=345元,机械费450×5元=2250元,管理费345×30%元=103.5元。
事件三可直接按土方开挖单价计算:[900×4.2×(1+20%)]元=4536元
则合理的费用索赔总额为:(345+2250+103.5+4536)元=7234.5元
4.建筑公司可以向厂方提供以下索赔文件。
(1)招标文件、工程合同及附件、业主认可的施工组织设计、工程图纸、技术规范;工程图纸、图纸变更、交底记录的送达份数及日期记录。
(2)工程各项经业主或监理工程师签认的签证;工程预付款、进度款拨付的数额及日期记录。
(3)工程各项往来信件、指令、信函、通知、答复及工程各项会议纪要。
(4)施工计划及现场实施情况记录;施工日报及工长工作日志、备忘录;工程现场气候记录,有关天气的温度、风力、降雨量等。
(5)工程送电、送水、道路开通、封闭的日期及数量记录;工程停水、停电和干扰事件影响的日期。
(6)工程有关部位的照片及录像等。
(7)工程验收报告及各项技术鉴定报告等。
(8)工程材料采购、订货、运输、进场、验收、使用等方面的凭据。
(9)国家、省、市有关影响工程造价、工期的文件、规定等。

Let us take a brief look at the planet on which we live. As Earth hurtles through space at a speed of 70,000 miles an hour, it spins, as we all know, on its axis, which causes it to be flattened at the Poles. Thus if you were to stand at sea level at the North or South Pole, you would be 13 miles nearer the centre of the earth than if you stood on the Equator.
The earth is made up of three major layers — a central core, probably metallic, some 4000 miles across, a surrounding layer of compressed rock, and to top it all a very thin skin of softer rock, only about 20 to 40 miles thick — that’s about as thin as the skin of an apple, talking in relative terms.
The pressure on the central core is unimaginable. It has been calculated that at the centre it is 60 million pounds to the square inch, and this at a temperature of perhaps 10,000 degrees Fahrenheit. The earth’s interior, therefore, would seem to be of liquid metal — and evidence for this is given by the behavior of earthquake.
When an earthquake occurs, shock waves radiate from the centre just as waves radiate. outwards from the point where a stone drops into a pond. And these waves pulsate through the earth’s various layers. Some waves descend vertically and pass right through the earth, providing evidence for the existence of the core and an indication that it is fluid rather than solid. Thus, with their sensitive instruments, the scientists who study earthquakes, the seismologists, can in effect X-ray the earth.
Iceland is one of the most active volcanic regions of the world. And it was to Iceland that Jules Verne sent the hero of his book A Journey to the Centre of the Earth. This intrepid explorer clambered down the opening of an extinct volcano and followed its windings until he reached the earth’s core. There he found great oceans, and continents with vegetation. This is conception of a hollow earth we now know to be false. In the 100 years since Jules Verne published his book, the science of vulcanology, as it is called, has made great strides. But even so the deepest man has yet penetrated is about 10,000 feet. This hole, the Robinson Deep mine in South Africa, barely scratches the surface; so great is the heat at 10,000 feet that were it not for an elaborate air-conditioning system, the miners working there would be roasted. Oil borings down to 20,000 feet have shown that the deeper they go, the hotter it becomes.
The temperature of the earth at the centre is estimated to be anything between 3,000 and 11,000 degrees Fahrenheit. Some scientists believe that this tremendous heat is caused by the breaking-down of radio-active elements, which release large amounts of energy and compensate for the loss of heat from the earth’s surface. If this theory is correct, then we are all living on top of a natural atomic powerhouse.

Since the publication of Jules Verne’s book, it has been proved that ______ .

A.( the centre of the earth is not hollow

B.( oil borings cannot go deeper than 20,000 feet

C.( there are active volcanic regions at the centre

D.( the earth is not in danger of exploding
