问答题

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。

指出该工程在招标过程中的不妥之处,并说明理由。

If you feel at present that you don’t have enough friends in your life, one reason may be that you have let yourself become too busy to make time for the relationships you already have. Starting and keeping friendship require effort and commitment(责任,义务,承诺).

Many of us let our lives become so busy with work and other commitments that we don’t get around to scheduling time for pleasure and renewal (叙旧) with the friends, relatives and acquaintances we already have.

Making the effort to call your friends more regularly and to accept more of the invitations you receive from others can improve your social life in a hurry!

Are there any people you could call right now and be assured of a pleasant welcome? Are there people that you could depend on to help you in time of difficulty? Can you have close talks with them? Do you have fun when you are together? Are you happy to have them in your life?

If you haven’t seen much of them lately, is it because you have become too busy? Have you grown apart? Was there an argument?

If the main reason you haven’t been getting together with the people you already know is that you have gotten too busy, take a good look at how you spend your time. Compare it with your real values and priorities(优先考虑的事) in life. Is your busy lifestyle really bringing you the quality of life that you want?

If you have become too busy for friends, why has this happened? Are you seeking material joys in your life at the expense of relationships with other human beings? Have you allowed your time to be over-committed because you never say ‘‘No” to anyone? Do you insist on doing things yourself that could be delegated to others? If so, why? Do you believe that everything depends on you?

Examine whether the way you are now spending your time exactly reflects your deepest values and priorities. Make sure that you schedule enough time for the things that are truly most important to you.

If you really want to keep friends in your life, make a space in your schedule, and a space in your heart for them.
