某城市的通信建设单项工程包括5个单位工程，建设单位为了引进竞争机制，将此项目的5个单位工程分别进行招标。建设单位请长期与其合作的某施工单位编制了标底，并向20家施工单位发出了招标邀请函，这些单位都购买了标书，并按照建设单位的要求向其交纳了估算合同价2%的投标保证金。在投标截止日，有A、B两家施工单位因路上堵车而未按规定时间提交投标文件，经向建设单位解释，建设单位接受了两单位的标书。在开标时，发现C施工单位的投标文件中对一个标段有两个报价。在开标结束后，C施工单位解释此问题是因为封装文件时疏忽所致，并说明了有效文件的版本。此次评标决定以最接近标底法确定中标人。在评标时，评标委员会发现D施工单位投标文件中的施工方案编制得比较优秀，只是其中的工作量与报价的内容不对应，因此，评标委员会请其对此问题作出澄清，以确定有效工作量。对于E施工单位的投标文件，评标委员会发现其中的工作量汇总时存在数据错误，因此请该单位对此进行补正。另外，还有其他个别的投标文件也存在含义不清、文字错误等问题，评标委员会也都请他们作了必要的说明或澄清。 经建设单位的权衡，最终确定了A、B、C、D、E5家施工单位分别中标一个单位工程。在签订合同时，建设单位请A施工单位再适当地把费用压低一些，A单位迫于无奈只好同意。最终，建设单位与5家施工单位签订了施工合同。建设单位在合同签订一个月以后，向未中标的各施工单位退还了投标保证金。 由于建设单位资金紧张，工程开工后一直未按合同约定向各施工单位拨付进度款。各施工单位为了尽快完成此项目，分别垫资完成此工程。未中标的施工单位在了解到此工程招标投标过程中的一些问题以后，欲对此建设单位的行为进行投诉。

回答下列问题：

（1）建设单位在此次招标活动中有哪些违规行为？建设单位怎样做才正确？

The Apple iPhone’s impact was widely evident (明显的) at the Consumer Electronics Show, as new touch－screen devices could be found everywhere.

The consumer electronics industry came unbuttoned in Las Vegas this week. At the annual Consumer Electronics Show, companies from around the world unveiled many devices boasting (以拥有…而自豪) touch – sensitive technology, rather than traditional push-button controls.

Motorola, Sony, and LG Electronics all showed off touch-screen phones this week. Microsoft Chairman Bill Gates praised and offered a touch-screen computer, the Surface, related to a flat panel TV for a tabletop. Even camera makers, such as Kodak，included touch-screen LCDs in their devices. Touch-screen tech has been in use for years，but the push to develop and weave it into consumer electronics gathered steam with the June introduction of Apple’s iPhone. “The touch-screen industry is really getting hot,” says Jennifer Colegrove, a senior analyst at iSuppli. “Since the iPhone came out, there are a lot of companies that did not have a relationship with touch screens before that decided, ‘OK, I want to make a touch screen, too.’”

The touch－screen tech ecosystem now includes more than 100 companies specializing in everything from smudge-proof (防污的) screens to sensors (传感器) able to detect fingers before they even contact the screen. Sales of leading touch-screen technologies，such as those used in mobile phones and navigation (航行) devices，are expected to rise to $ 4.4 billion in 2012, up from $ 2.4 billion in 2006，according to iSuppli estimates.
