问题 问答题


某工程项目为某市建设规划的重要项目之一,且已列入地方年度固定资产投资计划,概算已经主管部门批准,施工图及有关技术资料齐全。现决定对该项目进行公开招标,招标范包括土方基础工程、主体结构工程、设备安装及外墙装修工程,该项目基础工程包括地下室4层及挖孔桩。招标单位发布招标公告和资格预审通告后,省内外共有20家投标单位购买了资格预审文件并参加了资格预审,经招标工作委员会审定后,A、B、C3家单位通过了资格预审。随后招标单位向这3家投标单位发出了资格预审合格通知书和招标文件,接下来招标单位对这3家投标单位就招标文件所提出的所有问题统一作出书面答复。
在书面答复投标单位的提问后,招标单位又组织各投标单位进行了施工现场踏勘。在投标截止日期前10天,招标单位书面通知各投标单位,由于某种原因,决定将外墙装修工程从原招标范围内删除。
投标单位A在投标过程中,考虑到该工程地下室的施工需采用连续墙回封后,土方分层开挖,连续墙加设4~6层锚杆加固,土方开挖完毕后进行挖孔桩施工及地下室施工。而该工程地处繁华的商业区和密集的居民区,是交通十分繁忙的交通枢纽,采用爆破方法不太可行,因此在投标时将该方案的单价报得很低,而采用机械辅以人工破碎凿除基岩方案的报价较高。
投标单位B在送出投标文件后发现由于对招标文件的技术要求理解错误造成了报价估算有较严重的失误,遂赶在投标截止时间前10min向招标人递交了一份书面声明,要求撤回已提交的投标文件。

什么是公开招标什么是邀请招标

答案

参考答案:

解析:公开招标亦称无限竞争性招标,是指招标人以招标公告的方式邀请不特定的法人或者其他组织投标。邀请招标亦称有限招标,是指招标人以投标邀请书的方式邀请特定的法人或者其他组织投标。

When the Audet family turns on the lights at Blue Farm, they are using electricity that comes from cows—cow manure (粪肥), to be specific.

Cows produce a lot of wastes. One cow can create 30 gallons of wastes each day. Now imagine the output of over 1,000 cows at Blue Farm. That’s really a big amount.

When farmers clean their barns, they put the wastes in a big heap, and spread some of them on their fields for fertilizer(肥料). But now places like Blue Spruce Farm have a new way of using cow wastes. They use them to produce electricity.

Here’s how it works: A big machine moves back and forth cleaning the barn floor. “The cows aren’t bothered,” says Marie Audet. “They are animals of habit; they get used to it, and just lift one foot and then another to let it go by.”

The machine pushes the manure into a big 600-gallon tank like a small swimming pool. The tank is called a digester (化粪池) because what happens there is just like what happens inside a cow: Bacteria(细菌) get to work and continue to digest the manure.

Methane gas (甲烷、沼气)in the atmosphere is known as a “greenhouse” gas because it keeps heat just like a greenhouse does, causing our planet to warm up. That’s an environmental concern. But the digester has a good result. Its gas is kept and used to power electric generators (发电机).

At Blue Farm, the generators make enough electricity to power 400 homes. The Audet family sells the extra electricity they can’t use themselves.
