问题 问答题 案例分析题

某酒店工程,建筑面积28700mm,地下1层,地上15层,现浇钢筋混凝土框架结构。经过公开招标,建设单位与甲施工单位按照《建设工程施工合同(示范文本)》GF-2013-0201签订了施工总承包合同。工程施工过程中,发生了如下事件:事件一:某批次框架结构用的钢筋,施工总承包单位认为与上一批次已批准使用的是同一厂家生产的,没有进行进场复验等质量验证工作,直接投入了使用。事件二:7月份遇到罕见特大暴雨,导致全场停工,影响总工期10天;8月份又遇到季节性降雨,导致全场停工,影响总工期3天。施工单位向建设单位提出工期索赔13天。事件三:在竣工验收时,建设单位要求对已隐蔽的装饰基层重新剥离进行复验,施工单位认为施工过程中已按要求经监理工程师验收合格,故拒绝再次剥离开检查。经总监理工程师调解,停工2天后施工单位同意复验,复验结果满足设计及规范要求。施工单位上报停工2天、复验后重新恢复造成工期延误6天的两份工期索赔。事件四:工程完工后进行室内环境污染物浓度检测,结果不达标,经整改后再次检测达到相关要求。

事件一中,施工单位的做法是否妥当?列出钢筋质量验证时材质复验的主要内容。

答案

参考答案:

施工单位的做法不妥。在钢筋质量验证时材质复验的内容有:屈服强度、抗拉强度、伸长率和冷弯性能。

The fact that most Americans live in urban areas does not mean that they reside in the center of large cities. In fact, more Americans live in the suburbs of large metropolitan areas than in the cities themselves.
The Bureau of the Census regards any area with more than 2,500 people as an urban area, and does not consider boundaries of cities and suburbs.
According to the Bureau, the political boundaries are less significant than the social and economic relationships and the transportation and communication systems that integrate a locale. The term used by the Bureau for an integrated metropolis is an MSA, which stands for Metropolitan Statistical Area. In general, an MSA is any area that contains a city and its surrounding suburbs and has a total population of 50,000 or more.
At the present time, the Bureau reports more than 280 MSAs, which together account for 75 percent of the US population. In addition, the Bureau recognizes 18 megapolises, that is, continuous adjacent metropolitan areas. One of the most obvious megapolises includes a chain of hundreds of cities and suburbs across 10 states on the East Coast from Massachusetts to Virginia, including Boston, New York, and Washington, D.C. In the Eastern Corridor, as it is called, a population of 45 million inhabitants is concentrated. Another megapolis that is growing rapidly is the California coast from San Francisco through Los Angeles to San Diego.

According to the passage, where do most Americans live

A.In the center of cities.

B.In the suburbs surrounding large cities.

C.In rural areas.

D.In small towns.
