某机电安装公司承接了某厂区电气工程扩建改造项目，主要工作内容包括设备采购，设备安装，防雷接地安装等，建设单位要求安装公司严格按照合同施工，工期不得延误。安装公司根据工程合同要求向建设单位提交了施工进度计划图如下，数字代表施工天数。

在安装公司施工期间，监理工程师第 8 天下班前检查，发现设备安装刚开始安装 1 天，接口匹配工作已经进行了 3 天。照明施工刚开始进行了 1 天。监理工程师认为会影响到总工期，要求施工单位提交赶工计划。
施工单位召开了协调会，汇总出可以压缩工期的工序及费用的表格。随后编制了赶工计划，获得监理单位的批准。

安全生产监督管理部门在现场抽查，发现项目部未进行职业病危害预评价，也未提交职业病危害预评价报告。给予警告，责令机电公司限期改正。装公司施工期间始终严格执行“三检制”，并最终按原工期完成项目。

某分洪闸位于河道堤防上，河道堤防级别为5级。该闸在施工过程中发生如下事件：

事件1：闸室底板及墩墙设计采用C25W4F100混凝土。施工单位在混凝土拌合过程中掺入高效减水剂，并按照混凝土试验有关标准制作了混凝土试块，对混凝土各项指标进行试验。

事件2：为有效控制风险，依据《大中型水电工程建设风险管理规范》（GB/T50927-2013），施工单范围对施工过程中可能存在的主要风险进行了分析，把风险分为四大类：第一类为损失大、概率大的风险，第二类为损失小、概率大的风险，第三类为损失大、概率小的风险，第四类为损失小、概率小的风险，针对各类风险提出了风险规避等处置方法。

事件3：为加强工程施工安全生产管理，工程开工前，项目法人组织制定了本工程安全事故应急预案，包含了预警管理，制定了应急响应流程，包含①跟踪事态进展；②成立应急指挥部；③启动响应；④会商研究部署；⑤派遣现场工作组等。现场施工时2名施工人员不慎从作业高度为12.0m的高空坠落。

One basic weakness in a conservation system based wholly on economic motives is that most members of the land community have no economic value. Yet these creatures are members of the biotic community and, if its stability depends on its integrity, they are entitled to continuance.

When one of these non economic categories is threatened and, if we happen to love it, we invent excuses to give it economic importance. At the beginning of the century songbirds were supposed to be disappearing.(46)Scientists jumped to the rescue with some distinctly shaky evidence to the effect that insects would eat us up if birds failed to control them. The evidence had to be economic in order to be valid.

It is painful to read these roundabout accounts today. We have no land ethic yet, (47) but we have at least drawn nearer the point of admitting that birds should continue as a matter of intrinsic right, regardless of the presence or absence of economic advantage to us.

A parallel situation exists in respect of predatory mammals and fish-eating birds. (48) Time was when biologists somewhat overworked the evidence that these creatures preserve the health of game by killing the physically weak, or that they prey only on “worthless” species. Here again, the evidence had to be economic in order to be valid. It is only in recent years that we hear the more honest argument that predators are members of the community, and that no special interest has the right to exterminate the m f or the sake of a benefit, real or fancied, to itself.

Some species of tree have been“read out of the party” by economics-minded foresters because they grow too slowly, or have too low a sale value to pay as timber crops.(49) In Europe, where forestry is ecologically more advanced, the noncommercial tree species are recognized as members of native forest community, to be preserved as such, within reason. Moreover, some have been found to have a valuable function in building up soil fertility. The interdependence of the forest and its constituent tree species, ground flora, and fauna is taken for granted.

To sum up: a system of conservation based solely on economic self-interest is hopelessly lopsided. (50) It tends to ignore , and thus eventually to eliminate, many elements in the land community that lack commercial value,but that are essential to its healthy functioning. It assumes, falsely, that the economic parts of the biotic clock will function without the uneconomic parts.

【背景资料】

某新建水库工程由混凝土面板堆石坝、溢洪道、引水发电系统等主要建筑物组成。其中，混凝土面板堆石坝最大坝高95m，坝顶全长222m，坝体剖面图如图3所示。

承包人甲中标承担该水库工程的施工任务，施工过程中发生如下事件：
事件一：由于异常恶劣天气原因，工程开工时间比原计划推迟，综合考虑汛前形势和承包人甲的施工能力，项目法人直接指定围堰工程由分包人乙实施。承包人甲同时提出将混凝土面板浇筑分包给分包人丙实施的要求，经双方协商，项目法人同意了承包人甲提出的要求，并签订协议，协议中要求承包人甲对两个分包人的行为向项目法人负全部责任。
事件二：当大坝填筑到一定高程时，为安全度汛，承包人甲对堆石坝体上游坡面采取了防渗固坡处理措施。
事件三：混凝土面板采用滑模施工，脱模后的混凝土及时进行了修整和养护。

A公司中标城市现况主干道拓宽改造工程，加宽段道路基层为510mm厚石灰粉煤灰稳定碎石，面层为150mm厚沥青混凝土。
项目部在施工准备阶段组建了项目部，进行了图纸学习，形成了图纸会审记录。开工前，项目部根据有关资料，结合工程特点和自身施工能力编制了施工组织设计。施工组织设计包含了工程概况、施工方案、施工质量保证计划。为保证现况交通不断行，项目部编制了交通导行方案，以减少施工对群众社会经济生活的影响。
因为工期紧，石灰粉煤灰稳定碎石拟定分两层施工，在沥青混合料面层施工条件具备并请示公司领导后，项目经理立即下达了开工令。沥青混合料面层竣工后，施工单位进行了外观检查，沥青表面平整，没有脱落、推挤等现象，经过检测弯沉值、平整度、中线高程、横坡等项目，合格率达到98％。
