问题 问答题 案例分析题

某建设单位(甲方)与某施工单位(乙方)订立了某工程项目的施工合同。合同规定:采用单价合同,每一分项工程的工程量增减超过10%时,需调整工程单价;合同工期为25天,工期每提前1天奖励3000元,每拖后1天罚款5000元;乙方在开工前及时提交了施工网络进度计划如图所示,并得到甲方代表的批准。工程施工中发生如下几项事件:事件1:因甲方提供电源故障造成施工现场停电,使工作A和工作B的工效降低,作业时间分别拖延2天和1天;多用人工8个和10个工日;工作A租赁的施工机械每天租赁费为560元,工作B的自有机械每天折旧费280元。事件2:为保证施工质量,乙方在施工中将工作C原设计尺寸扩大,增加工程量16m3,该工作全费用单价为87元/m3,作业时间增加2天。事件3:因设计变更,工作E的工程量由300m3增至360m3,该工作原全费用单价为65元/m3,经协商调整全费用单价为58元/m3。事件4:鉴于该工程工期较紧,经甲方代表同意乙方在工作G和工作I作业过程中采取了加快施工的技术组织措施,使这两项工作作业时间均缩短了2天,该两项加快施工的技术组织措施费分别为2000元、2500元。其余各项工作实际作业时间和费用均与原计划相符。

每项事件的工期补偿是多少天?总工期补偿多少天?

答案

参考答案:

事件1:工期补偿1天,因为工作B在关键线路上其作业时间拖延的1天影响了工期。但工作A不在关键线路上其作业时间拖延的2天,没有超过其总时差,不影响工期。事件2:工期补偿为0天。事件3:工期补偿为0天,因工作E不是关键工作,增加工程量后作业时间增加:原计划:300/5=60(m3/天);增加工作量:360-300=60(m3);增加工期:60/60=1(天),没有超过工作E的总时差,不影响工期。事件4:工期补偿0天。总计工期补偿:1+0+0+0=1(天)。

How should one invest a sum of money in these days of inflation (通货膨胀) Left in a bank it will hardly keep its value, however high the interest rate is. Only a brave man, or a very rich one, dares to buy and sell on the Stock Market. Today it seems that one of the best ways to protect your savings, and even increase your wealth is to buy beautiful objects from the past. Here I am going to offer some advice on collecting antique clocks, which I personally consider are among the most interesting of antiques.
I sometimes wonder what a being from another planet might report back about our way of life. "The planet Earth is ruled by a mysterious creature that sits or stands in a room and makes a strange ticking sound. It has a face with twelve black marks and two hands. Men can do nothing without its permission, and it fastens its young round people’s wrists so that everywhere men go they are still under its control. This creature is the real master of Earth and men are its slaves."
Whether or not we are slaves of time today depends on our culture and personality, but it is believed that many years ago kings kept special slaves to tell the time. Certain men were very clever at measuring the time of day according to the beating of their own hearts. They were made to stand in a fixed place and every hour or so would shout the time. So it seems that the first clocks were human beings.
However, men quickly found more convenient and reliable ways of telling the time. They learned to use the shadows cast by the sun. They marked the hours on candles, used sand in hourglasses, and invented water-clocks. Indeed, any serious student of antiques should spend as much time as possible visiting palaces, stately homes and museums to see some of the finest examples of clocks from the past.
Antique clocks could be very expensive, but one of the joys of collecting clocks is that it is still possible to find quite cheap ones for your own home. After all, if you are going to be ruled by the time, why not invest in air antique clock and perhaps make a future profit

The purpose of the passage is ______.

A.to introduce the culture of antique clocks

B.to offer some advice on collecting antique clocks

C.to compare different ways to make a future profit

D.to tell people that we are the slaves of clocks
