【背景资料】 某新建办公大楼的招标文件写明:承包范围是土建工程、水电及设备安装工程、装饰装修工程;采用固定总价方式投标,风险范围内价格不作调整,但中央空调设备暂按120万元报价;质量标准为合格,并要求创省优质工程奖,但未写明奖罚标;合同采用《建设工程施工合同(示范文本)》GF一2013—0201。 某施工单位以3260万元中标后,与发包方按招标文件和中标人的投标文件签订了合同。合同中还写明:发包方在应付款中扣留合同额5%,即163万元作为质量履约保证金,若工程达不到国家质量验收标准,该质量履约保证金不再返还;逾期竣工违约金每天1万元;暂估价设备经发承包双方认质认价后,由承包人采购。 合同履行过程中发生了如下事件: 事件1:主体结构施工过程中发生了多次设计变更,承包人在编制的竣工结算书中提出设计变更实际增加费用共计70万元,但发包方不同意该设计变更增加费。 事件2:中央空调设备经比选后,承包方按照发包方确认的价格与设备供应商签订了80万元采购合同。在竣工结算时,承包方按投标报价120万元编制结算书,而发包方只同意按实际采购价80万元进行结算。双方为此发生争议。 事件3:办公楼工程经四方竣工验收质量为合格,但未获得省优质工程奖。发包方要没收163万元质量保证金,承包人表示反对。 事件4:办公楼工程实际竣工日期比合同工期拖延了10d,发包人要求承包人承担违约金10万元。承包人认为工期拖延是设计变更造成的,工期应顺延,拒绝支付违约金。 发包人不同意支付因设计变更而实际增加的费用70万元是否合理?说明理由。

Camping Camping wild is a wonderful way to experience the natural world and, at its best, it makes little environmental influence. But with increasing numbers of people wanting to escape into the wilderness, it is becoming more and more important to camp unobtrusively (不引人注目地) and leave no mark. Wild camping is not permitted in many places, particularly in crowded lowland Britain. Wherever you are, find out about organizations responsible for managing wild spaces, and contact them to find out their policy on camping and shelter building. For example, it is fine to camp wild in remote parts of Scotland, but in England you must ask the landowner's permission, except in national parks. Camping is about having relaxation, sleeping outdoors, experiencing bad weather, and making do without modern conveniences. A busy, fully-equipped campsite (野营地) seems to go against this, so seek out smaller, more remote places with easy access to open spaces and perhaps beaches. Better still, find a campsite with no road access: walking in makes a real adventure. Finding the right spot to camp is the first step to guaranteeing a good night's sleep. Choose a campsite with privacy and minimum influence on others and the environment. Try to use an area where people have obviously camped before rather than creating a new spot. When camping in woodland, a void standing dead trees, which may fall on a windy night. Avoid animal runs and caves, and possible homes of biting insects. Make sure you have most protection on the windward side. If you make a fire, do so downwind of your shelter, always consider what influence you might have on the natural world. Avoid damaging plants. A good campsite is found, not made — changing it should be unnecessary. ometimes you need to make electricity.()
