某大型工业项目的主厂房工程,发包人通过公开招标选定了承包人,并依据招标文件和投标文件,与承包人签订了施工合同。合同中部分内容如下:

(1)合同工期160日,承包人编制的初始网络进度计划,如图1所示。

由于施工工艺要求,该计划中C、E、I 3项工作施工需使用同一台运输机械;B、D、H3项工作施工需使用同一台吊装机械。上述工作由于施工机械的限制只能按顺序施工,不能同时平行进行。

(2)承包人在投标报价中填报的部分相关内容如下。

①完成A、B、c、D、E、F、G、H、I 9项工作的人工工日消耗量分别为:100、400、400、300、200、60、60、90、100个工日。

②工人的日工资单价为50元/工日,运输机械台班单价为2400元/台班,吊装机械台班单价为1200元/台班。

③分项工程项目和措施项目均采用以直接费为计算基础的工料单价法,其中的间接费费率为18%,利润率为7%,税金按相关规定计算,施工企业所在地为县城。

(3)合同中规定:人员窝工费补偿25元/工日,运输机械折旧费1000元/台班,吊装机械折旧费500元/台班。

在施工过程中,由于设计变更使工作E增加了工程量:作业时间延长了20日,增加用工100个工日,增加材料费2.5万元,增加机械台班20个,相应的措施费增加1.2万元。同时,E、H、I的工人分别属于不同工种,H、I工作分别推迟20日。

     Last August, Joe and Mary Mahoney began looking at colleges for their 17-year-old daughter,

Maureen. With a check list of criteriain hand, the Dallas family looked around the country visiting half

a dozen schools. They sought a university that offered the teenager's intended major, one located near a

large city, and a campus where their daughter would be safe.      

     "The safety issue is a big one," says Joe Mahoney, who quickly discovered he wasn't alone in his

worries. On campus tours other parents voiced similar concerns, and the same question was always asked: What about crime? But when college officials always gave the same answer, "That's not a problem here. " Mahoney began to feel uneasy.      

     "No crime whatsoever?" comments Mahoney today. "I just don't buy it. "Nor should he; in 1999 the

US Department of Education had reports of nearly 400,000 serious crimes on or around our campuses. " Parents need to understand that times have changed since they went to college," says David Nichols,

author of Creatinga Safe Campus. "Campus crime mirrors the rest of the nation. "    

     But getting accurate information isn't easy. Colleges must report crime statistics (统计数字) by law, but some hold back for fear of bad publicity, leaving the honest ones looking dangerous. "The truth may not

always be obvious, "warns S. Daniel Carter of Security on Campus, Inc. , the nation's leading campus

safety watchdoggroup.

to find out major crime issues and effective solutions.
