A Melting Greenland Weighs Perils Against Potential By ELISABETH ROSENTHAL October 08, 2012. NARSAQ, Greenland — As icebergs in the Kayak Harbor pop and hiss while melting away,this remote Arctic town and its culture are also disappearing in a changing climate.Narsaq’s largest employer, a shrimp factory, closed a few years ago after the crustaceans fled north to cooler water. Where once there were eight commercial fishing vessels, there is now one.As a result, the population here, one of southern Greenland’s major towns, has beenhalved to 1,500 in just a decade. Suicides are up.Andrew Testa for The New York Times.“Fishing is the heart of this town,” said Hans Kaspersen, 63, a fisherman. “Lots of people have lost their livelihoods.”But even as warming temperatures are upending traditional Greenlandic life, they are also offering up intriguing new opportunities for this state of 57,000 — perhapsnowhere more so than here in Narsaq.Vast new deposits of minerals and gems are being discovered as Greenland’s massive ice cap recedes, forming the basis of a potentially lucrative mining industry.One of the world’s largest deposits of rare earth metals — essential for manufacturing cellphones, wind turbines and electric cars —sits just outside Narsaq.This could be momentous for Greenland, which has long relied on half a billion dollars a year in welfare payments from Denmark, its parent state. Mining profits could help Greenland become economically self sufficient and render it the first sovereign nation created by global warming.“For me, I wouldn’t mind if the whole ice cap disappears,” said Ole Christiansen, the chief executive of NunamMinerals, Greenland’s largest homegrown mining company, as he picked his way along a proposed gold mining site up the fjord from Nuuk, Greenland’s capital. “As it melts, we’re seeing new places with very attractive geology.”The Black Angel lead and zinc mine, which closed in 1990, is applying to reopen this year, said Jorgen T. Hammeken-Holm, who oversees licensing at the country’s mining bureau, “because the ice is in retreat and you’re getting much more to explore.”The Greenlandic government hopes that mining will provide new revenue. In granting Greenland home rule in 2009, Denmark froze its annual subsidy, which is scheduledto be decreased further in the coming years.Here in Narsaq, a collection of brightly painted homes bordered by spectacular fjords,two foreign companies are applying to the government for permission to mine.“This is huge; we could be mining this for the next 100 years,” said Eric Sondergaard, a geologist with the Australian-owned company Greenland Minerals and Energy, whowas on the outskirts of Narsaq one day recently, picking at rocks on a moon-likeplateau rich with an estimated 10.5 million tons of rare earth ore.That proximity promises employment, and the company is already schooling some young men in drilling and in English, the international language of mine operations. It plans to build a processing plant, a new port and more roads. (Greenland currently has none outside of settled areas.) Narsaq’s tiny airport, previously threatened with closure from lack of traffic, could be expanded. A local landlord is contemplating converting an abandoned apartment block into a hotel.“There will be a lot of people coming from outside and that will be a big challenge since Greenlandic culture has been isolated,” said Jasper Schroder, a student home in Narsaq from university in Denmark.

案例分析题背景资料为响应国家“节能减排”、“上大改小”的环保要求，某水泥厂把原有的一条日生产1000吨的湿法生产线，在部分设备不变动的基础上，改成日产1000吨的干法生产线，同时将前几年因资金困难中途停建的一条日产4000吨干法生产线恢复建设；另外征用土地，再独立建设一天日产8000吨干法生产线。建设单位实施三项工程各自独立核算，分别管理，以PC承包形式分别招投标。最终A、B、C公司分别承担了三种不同类型的工程，C公司还同时承担了全厂110Kv变电工程。工程以固定综合单价计算，工程量按实调整，并明确施工场地、施工道路、100吨以上大型吊车及其操作司机由建设单位提供。施工过程中发生下列事件：事件1：A公司在设备采购时，在性价比方面对制造厂商进行了咨询，从中选择了备选厂商，进行了邀请招标。然而在制造过程中仍出现个别厂商因交通运输不便或生产任务过于饱和拖延了交货期；个别厂商因加工能力不足或管理不善满足不了质量要求。事件2：B公司在施工过程中：因设备延期交付，延误工期5天，并发生窝工费及其他费用5万元；150吨吊车在吊装过程中因司机操作失误致使吊车零部件部分损坏造成停工4天，发生窝工费2万元；因大暴雨成灾停工3天；设备安装工程量经核实增加费用4万元；因材料涨价，增加费用20万元；非标准件制作安装因设计变更增加费用16万元。事件3：C公司完成110Kv变电站的施工后，编制了变压器送电试运行方案，变压器空载试运行12小时，记录了变压器的空载电流和一次电压，在验收时没有通过。事件4：在球磨机基础验收时，未能对地脚螺栓孔认真检查验收，致使球磨机的地脚螺栓无法正常安装。分别计算事件2中B公司可向建设单位索赔的费用和工期。

案例分析题背景资料某机电工程公司施工总承包了一项大型气体处理装置安装工程。气体压缩机厂房主体结构为钢结构。厂房及厂房内的2台额定吊装重量为35t的桥式起重机（简称桥吊）安装分包给专业安装公司。气体压缩机是气体处理装置的核心设备，分体到货。机电工程公司项目部计划在厂房内桥吊安装完成后，用桥吊进行气体压缩机的吊装，超过30t的压缩机大部件用2台桥吊抬吊的吊装方法，其余较小部件采用1台桥吊吊装，针对吊装作业失稳的风险采取了相应的预防措施。施工过程中发生了如下事件：事件1：专业安装公司对桥吊安装十分重视。施工前编制了专项方案，组织了专家论证，上报了项目总监理工程师。总监理工程师审查方案时，要求桥吊安装实施监督检验程序。事件2：专业安装公司承担的压缩机钢结构厂房先期完工，专业安装公司向机电工程公司提出工程质量验收评定申请。在厂房钢结构分部工程验收中，由项目总监理工程师组织建设单位、监理单位、机电工程公司、专业安装公司、设计单位的规定人员进行了验收，工程质量验收评定为合格。事件3：工程进行到试运行阶段，机电公司拟进行气体压缩机的单机试运行。在对试运行条件进行检查时，专业监理工程师提出存在2项问题：（1）气体压缩机基础二次灌浆未达到规定的养护时间，灌浆层强度达不到要求；（2）原料气系统未完工，不能确保原料气连续稳定供应。因此，监理工程师认为气体压缩机未达到试运行条件。写出压缩机钢结构厂房工程质量验收合格的规定。
