题目:

某机电工程采用EPC/交钥匙总承包的方式进行公开招标,并在国家发改委依法指定的媒体上发布了招标公告和资格预审公告。公告中明确说明了承包商报名时间及提供的资料;工程的基本情况;投标人需提交标书费用、押金、投标保函的要求;投标人获取和送达标书的方式、地点和起止时间、开标日期、时间和地点。招投标过程及施工过程中发生下列事件:

事件一:经资格预审后,共有A、B、C、D、E五家总承包商投递了资料,并按规定时间和要求完成了标书的购买,编写和投标。其中D单位未办理投标保函,被招标单位取消资格。

事件二:开标后,评委认为C单位不符合投标资格,故也被取消投标资格,经评委公平、公正评审后A公司中标。

事件三:A公司把一台压力球形储罐的安装工程分包给具有相应安装资质的E公司施工,由于球形储罐体积大,解体运输到现场,E公司办完压力容器安装进场的相关手续后,现场对球形储罐地面组对焊接,整体吊装。

事件四:项目实施过程中,A公司因高空坠落死亡一人,设备吊装重伤三人。

事件五:一台主机试运转时振动过大,经分析本台设备垫铁安装时无垫铁布置图,且不是采用坐浆法施工,而是采用老式垫铁与基础研磨的施工方法,振动可能是因垫铁的安装质量出了问题。

本案例可能会存在哪些垫铁安装质量问题?
