问答题 案例分析题

某钢筋混凝土框架结构标准厂房建筑,高两层,无地下室,框架柱柱距7.6m。通过公开招标程序,某施工单位与建设单位参照《建设工程施工合同(示范文本)》GF-2013-0201签订的承包合同部分内容如下:工程合同总价2100万元,工程价款采用调值公式动态结算;该工程的人工费可调,占工程价款的35%;材料有4种可调:材料1占5%,材料2占15%,材料3占15%,材料4占10%。建设单位在开工前向承包商支付合同价的15%预付备料款,主要材料及构配件金额占合同总额的65%。竣工前全部结清。开工前,施工单位制定了完整的施工方案,采用预拌混凝土,钢筋现场加工,采用覆膜多层板作为结构构件模板,模架支撑采用碗扣式脚手架。施工工序安排框架柱单独浇筑,第二步梁与板同时浇筑。施工过程发生如下事件:事件一:结构设计按最小配筋率配筋,设计中有采用HPB235级Φ12mm钢筋,间距200mm。由于当地建材市场HPB235级直径12mm钢筋被淘汰,施工单位征得监理单位和建设单位同意后,按等强度折算后,用HRB335级直径12mm(间距250mm)的钢筋进行代换,保证整体受力不变,并按此组织实施。事件二:二层梁板施工阶段天气晴好,气温16~27℃。梁板模板安装拼接整齐、严密并验收完毕后,进行钢筋的安装,且钢筋绑扎经验收符合规范要求。在混凝土浇筑前,用水准仪抄平,保证每一构件底模表面在同一个平面上,无凹凸不平问题,开始浇筑混凝土,并现场制作混凝土试件。浇筑完毕20小时覆盖并浇水养护。10天后从标准养护室取出一组试件送检试压,其强度达设计强度的80%,施工单位认为已超过设计强度75%,向监理提出拆除底模与架体支撑的申请。事件三:某分项工程20%的工程量改变质量标准,采用其他做法施工,在合同专用条款中未对该项变更价款有约定。施工单位按变更指令施工,在施工结束后的下一个月上报工程款申请的同时,还上报了该设计变更的变更估价申请,监理工程师不同意变更估价。事件四:合同中约定,根据人工费和四项主要材料和价格指数对总造价按调值公式法进行调整。各调值因素的比重、基准和现行价格指数如下表:

竣工结算时,施工单位按调值公式法重新计算实际结算价款。

事件四中,列式计算经调整后的实际结算价款是多少万元(保留两位小数)?

A job is more than just a job,especially to the older generation.“It’s not the money that matters,but the sense of self­worth,” 56­year­old Cheng Wonlan said.So,every day Ms Cheng carries a bag of parcels,letters and documents of all shapes and sizes and does her rounds in North Point.She’s a courier(快递人员).

Five years ago,Ms Cheng was a nurse at a private clinic.She had worked there for almost 30 years but was made jobless when the doctor migrated(移居).It was extremely difficult for her to find another job.“People do not trust my ability when they learn how old I am,” she said.After two years of searching,the mother of two eventually found another nursing job.But then after two years,she quit.Why?

“My colleagues were young and they didn’t understand me because of my age.They often asked me,‘You are so old;what are you working for?’ I was very unhappy.” she said.So while the rest of her family left for work,she was left to lonely boredom at home.The urge to work drove her to suffering.Then,one of Ms Cheng’s neighbours told her about Employee’s Retraining Board (ERB) offering retraining courses for older people on specific occupations,such as convenience store assistants,junior clerks and so on.

“I was interested in courier work.I didn’t think my age was a barrier because I was fit and healthy.So I thought why not give it a try.” she said.Upon graduation from the ERB,Ms Cheng was offered a job by the Speeding Shuttle Courier Service Company Limited.But then Ms Cheng was faced with a conflict:she was caught between honour and employment.It took Ms Cheng 24 hours to make up her mind and eventually came to the conclusion that there was nothing wrong or embarrassing about doing the job.So she took heart and went off to work as a courier.

Ms Cheng’s employer is delighted with her,“Ms Cheng has been working with us for two months and has shown a good responsible attitude to work.”Anthony Chong,who runs the company,said.Currently,Mr Chong has 60 couriers working for his company:five of them are over fifty,four of whom have been through the ERB plan.Mr Chong said he hired older people because they were able and reliable.“Age is not an important factor but attitude is.Many old people are more capable than the youngsters.They will not run from difficulties but the young ones will,” he said.“It is not easy to recruit (招募) young people since they shy away from hardship and challenges.”
