某工程采用公开招标方式,招标人5月1日在指定媒体上发布了招标公告,5月6日至5月12日发售了招标文件,共有A、B、C、D四家投标人购买了招标文件。在招标文件规定的投标截止日(6月5日)前,四家投标人都递交了投标文件。开标时,投标人D因其投标文件的签署人没有法定代表人的授权委托书而被招标管理机构宣布为无效投标。

该工程评标委员会于6月15日经评标确定投标人A为中标人,并于6月26日向中标人和其他投标人分别发出中标通知书和中标结果通知,同时通知了招标人。

发包人与承包人A于7月10日签订了工程承包合同,合同约定的不含税合同价为6948万元,工期为300天;合同价中的间接费以直接费为计算基数,间接费率为12%,利润率为5%。

在施工过程中,该工程的关键线路上发生了以下几种原因引起的工期延误。

(1) 由于发包人原因,设计变更后新增一项工程于9月28日至10月7日施工(新增工程款为160万元);另一分项工程的图纸延误导致承包人于10月27日至11月12日停工。

(2) 由于承包人原因,原计划于10月5日早晨才到场的施工机械直到10月26日早晨才到场。

(3) 由于天气原因,连续多日高温造成供电紧张,该工程所在地区于10月3日至10月5日停电,另外,该地区于10日24日早晨至10月28日晚下了特大暴雨。

在发生上述工期延误事件后,承包人A按合同规定的程序向发包人提出了索赔要求。经双方协商一致,除特大暴雨造成的工期延误事件外,对其他应予补偿的工期延误事件,既补偿直接费又补偿间接费,间接费补偿按合同工期每天平均分摊的间接费计算。

(费用计算结果保留2位小数)

该工程所在地市政府规定,高温期问施工企业每日工作时间减少1小时,企业必须给职工每人每天10元高温津贴。若某分项工程的计划工效为1.50m2/小时,计划工日单价为50元,高温期间的实际工效降低10%,则高温期间该分项工程每平方米人工费比原计划增加多少元?

The story I am going to tell you happened about three years ago when I started to learn how to drive. At first, I was very frightened, and I thought I could never learn how to drive a car. Driving a car frightened me because in my home country women never drive, but in the United States every woman has to know how to drive. My husband paid an instructor to teach me how to drive. After that, my husband practiced with me for a long time. My husband always told me that I had to learn. It was important to me and my family.

However, I couldn’t get my license right away. I failed my driving test two times. After practicing for a long time, I decided to go for my third driving test. I had failed my first test because I was very nervous. Everybody encouraged me to continue practicing. Three weeks later, I decided to try it again, but I failed again.
