【背景资料】某市外环路路基平均填土高度18m。该路段因沿黄河大堤，地下水位高(现有黄河河床标高比路面设计高程高出2～3m)，而且处于雨期积水地区，土质大部分为黄河粉砂土，少量粉质黏土，全线大部分路段为软弱地基路段(地基承载力平均10～80kPa)。因此，设计单位与施工单位共同研究，依据当地材料状况、施工条件与工期要求，采用以下软土地基的处理方法：
（1）换填。K1+000~K1+350，长350m，K3+775～K4+270，长495m两段粉砂土路段，生活垃圾堆放点和居民旧生活区，在清除垃圾及民用拆迁旧房基，挖至原粉砂二地层后做二灰土(2：8)，犁拌，厚度40cm，碾压密实度90％以上，经土工检测后再做二灰稳定碎石层40cm。
(2)土工布处治。K1+780～K1+980，长200m路段地下水位高，土质差，苇根很多而深，采用带眼双面胶无纺布(150～2009／m2，抗拉强度为2050kN／m)铺垫。
(3)K6+200～K6+350，长150m，位于黄河沉砂池上，粉砂土质、含水量大，地下水位高，采用孔深1～1．2m，间距60cm，梅花形摆排的生石灰桩挤密。生石灰桩施工时工艺程序如下：整平地面一成孔一空气压缩机注入生石灰一封紧生石灰桩孔。
在施工至K5+200～K5+350时，由于该路段缺乏地质资料未发现软土，地基未做加固设计，在填土至5．8～6．3m时发生滑塌，因征地困难，不能做反压护道，施工方考虑工期时间要求充裕，淤泥层厚度≤3m，决定采用自然挤淤处理。
【背景资料】A 市某焦化企业厂区占地面积约20×104m2 ，主要生产焦炭、焦黑、硫黄、粗苯及焦油等化工产品，炼焦车间建设36 和42 孔JN43-98 型宽炭化室、双连火道、废气循环、下喷、单热式捣固焦炉，年产冶金焦60×104 t 。事故发生部位采用捣固煤饼，侧装高温干馏，湿法熄焦工艺。
2019 年3 月21 日，该企业预对厂内煤气管道进行维护清洗，制定了相关的作业规程和安全应急预案，并在作业前对工人进行了技术交底。上午9 点工程开始后，现场人员为了保证工程进度快速恢复生产，用自制铁把直接清理管道内的残留杂质。在工作到下午1点钟时开始有工作人员出现头痛情况，值班工长在请示领导后现场加装了轴流风机保证通风，紧接着继续开始工作，下午2 点钟现场突然发生爆燃。事故造成4 人死伤， 25 人烧伤，直接经济损失800 万元。经调查，事故原因是管道未堵盲板，结果导致大量煤气外泄，外泄的煤气与通风的空气混合后遇到引火源产生爆燃。
事故发生后，该企业积极开展内部检查，清查隐患，创建安全标准化体系。对受限空间作业严格管控，施行作业票值制度，要求严格按照作业规程，做好现场检测监测，劳动防护用品佩戴，并将责任落实到位，并对受伤的职工进行了安抚和慰问。
根据以上场景，回答下列问题：
安装公司承接了某所大学图书馆的消防安装工程，工程内容包括：消防给水及消火栓系统、自动喷水灭火系统、高压细水雾灭火系统和火灾自动报警系统等的安装。该图书馆共三层，总建筑面积为4200m2， 楼高为14m， 其中一、二层为展览室，采用自动喷水灭火系统；三层为藏书室，采用高压细水雾灭火系统。
工程开工前，项目部完成了施工组织设计及施工方案编制等技术准备工作，并由方案编制人员向施工作业人员进行了施工技术交底。交底时使用了大量的细部节点图，如利用图2对消防水泵接合器组装进行交底。
工程开工后，监理单位在审查点型感烟火灾探测器进场报验资料时，发现缺少3C认证证书，经补充资料后通过验收。
工程完工后，建设单位组织设计单位、监理单位、施工单位进行了消防工程验收，涉及消防的各分部分项工程验收合格，并在验收合格之日起5个工作日内向消防设计审查验收主管部门办理了消防验收备案。

The decline in American manufacturing is a common refrain, particularly from Donald Trump. “We don’t make anything anymore,” he told Fox News, while defending his own made-in-Mexico clothing line.
Without question, manufacturing has taken a significant hit during recent decades, and further trade deals raise questions about whether new shocks could hit manufacturing.
But there is also a different way to look at the data.
Across the country, factory owners are now grappling with a new challenge: Instead of having too many workers, they may end up with too few. Despite trade competition and outsourcing, American manufacturing still needs to replace tens of thousands of retiring boomers every year. Millennials may not be that interested in taking their place. Other industries are recruiting them with similar or better pay.
For factory owners, it all adds up to stiff competition for workers – and upward pressure on wages. “They’re harder to find and they have job offers,” says Jay Dunwell, president of Wolverine Coil Spring, a family-owned firm. “They may be coming [into the workforce], but they’ve been plucked by other industries that are also doing as well as manufacturing,” Mr. Dunwell has begun bringing high school juniors to the factory so they can get exposed to its culture.
At RoMan Manufacturing, a maker of electrical transformers and welding equipment that his father cofounded in 1980, Robert Roth keeps a close eye on the age of his nearly 200 workers. Five are retiring this year. Mr. Roth has three community-college students enrolled in a work- placement program, with a starting wage of $13 an hour that rises to $17 after two years.
At a worktable inside the transformer plant, young Jason Stenquist looks flustered by the copper coils he’s trying to assemble and the arrival of two visitors. It’s his first week on the job. Asked about his choice of career, he says at high school he considered medical school before switching to electrical engineering. “I love working with tools. I love creating,” he says.
But to win over these young workers, manufacturers have to clear another major hurdle: parents, who lived through the worst US economic downturn since the Great Depression, telling them to avoid the factory. Millennials “remember their father and mother both were laid off. They blame it on the manufacturing recession,” says Birgit Klohs, chief executive of The Right Place, a business development agency for western Michigan.
These concerns aren’t misplaced: Employment in manufacturing has fallen from 17 million in 1970 to 12 million in 20When the recovery began, worker shortages first appeared in the high-skilled trades. Now shortages are appearing at the mid-skill levels.
“The gap is between the jobs that take no skills and those that require a lot of skill,” says Rob Spohr, a business professor at Montcalm Community College. “There’re enough people to fill the jobs at McDonalds and other places where you don’t need to have much skill. It’s that gap in between, and that’s where the problem is.”
Julie Parks of Grand Rapids Community College points to another key to luring Millennials into manufacturing: a work/life balance. While their parents were content to work long hours, young people value flexibility. “Overtime is not attractive to this generation. They really want to live their lives,” she says.

【背景资料】
某施工单位承接了某高速公路 A 合同段的施工任务，其中包括 8km 的路基、路面工程和一座跨径80m 的桥梁施工。该合同段土质以松散砂土和黏土为主，土质含水量为20%，路基施工中有大量土方需转运 200～300m。
施工前，项目部组织编写了施工组织设计，并将路面分成三个工作量相等的施工段，基层和面层各由一个专业作业队施工。基层的三个施工段按每段 25d，面层的三个施工段按每段 15d等节拍组织流水施工，并绘制了总体进度计划如图所示。 
合同约定工期为300d，并规定每提前工期 1d，奖励0.5 万元；每拖延工期1d，罚款 0.8万元。
在施工准备阶段，项目部将桥梁工程的基础施工指派给某专业作业队实施，但由于种种原因，施工时间需调整为 70d。
在桥梁基础施工中，由于监理工作失误，使该桥施工暂停 10d，导致人员和租赁的施工机具窝工10d，项目部在规定时间内就此向监理公司提出了费用索赔。
某国有资金投资的项目，采用工程量清单公开招标规定了最高限价，要求工程量清单的项目编码等内容必须与招标人提供的内容保持一致。合同工期190天。招标人使用《建设工程施工合同（示范文本）》时，对认为不适用本项目的通用条款进行了删减。竣工结算约定：风险费用包含在综合单价中，全部风险由施工单位承担。工程量按实结算，但竣工结算款总额不得高于招标最高限价。
招标人A共八家单位参加了投标。投标人A针对2万m2的模板工程。提出了两种可行方案。依据价值工程(W=F/C)进行比选。方案一的成本为146万元。功能系数为0.54。方案二的成本为139万元，功能系数为0.46。投标人F在投标报价中降低了部分清单项目的综合单价和措施项目费中的二次搬运费，将招标清单中材料暂估价下调3%。工程在安装调试阶段，由于雷电发生火灾，火灾结束后48小时内，施工单位向项目监理单位通报了火灾损失情况：工程本体损失110万元总价值210万的待安装设备报废：施工单位立烧伤人员医疗费及补偿费60万元粗赁施工设备损坏赔偿费25万元。其他单位停放在现场价值16万元的汽车被烧毁。另外工程因火灾停工5天，造成施工单位施工机械闲置损失费2万元，事故现场保卫人员费用支出2万元。工程清理、修复费用约200万元。监理单位审核后上报了建设单位。
