某承包商通过资格预审后,对招标文件进行于仔细分析,发现招标单位所提出的工期要求过于苛刻,且合同条款中规定每拖延l天工期罚合同价的1%。若要保证实现该工期要求,必须采取特殊措施,从而大大增加成本;还发现原设计方案过于保守。因此,该承包商在投标文件中说明业主的工期要求难以实现,因而按自己认为的合理工期(比业主要求的工期增加6个月)编制施工进度计划并据此报价;还建议变更原设计方案,并对这两种设计方案进行了技术、经济分析和比较,证明变更原设计方案不仅能保证工程结构的可靠性和安全性、提高空间利用的灵活性,而且可降低造价约3%。该承包商将技术标和商务标分别封装,在封口处加盖本单位公章和项目经理签字后,在投标截止日期前1天上午将投标文件报送招标单位。次日(即投标截止日当天)下午,在规定的开标时间前1小时,该承包商又递交了一份补充材料,其中声明将原报价降低4%。但是,招标单位的有关工作人员认为,根据国际上“一标一投”的惯例,一个承包商不得递交两份投标文件,因而拒收承包商的补充材料。
开标会由市招投标办的工作人员主持,市公证处有关人员到会,各投标单位代表均到场。开标前,市公证处人员对各投标单位的资质进行审查,并对所有投标文件进行审查,确认所有投标文件均有效后,正式开标。主持人宣读投标单位名称、投标价格、投标工期和有关投标文件的重要说明。

If you dream of going someplace warm to escape the cold winter weather,a trip to a recently discovered planet would certainly warm you right up.The planet,named

OGLE-TR-56b,has temperatures of more than 3,000°F.“This is the hottest planet we know about,”says Dr Dimitar Sasselov,a scientist who led the discovery team.“It is hot enough to have an iron fog and to rain hot iron droplets(细沫).”

The new planet is 30 times farther away than any planet discovered by scientists

before.It is in the Milky Way(银河)but it is not in our solar(太阳的)system.The new planet moves around a star much like our sun,however scientists discovered the planet by using a new planetsearching method called transit technique.They were able to catch sight of the planet when it moved in front of its star,causing the star's light to dim(变暗).Scientists compare the method to discovering the shadow of a bee flying in front of a searchlight 200 miles away.“We believe the door has been opened wide to go and discover planets like the Earth,”says Sasselov.
