In life, people come across many experiences, which they remember all their lives. I had a similar experience, too.

It was the day of my last paper of the final exam. My uncle had invited me to spend my vacation with him. I was especially excited about the invitation that my uncle had given me to stay with him for a few days in Cambridge.

On that day we got into our classroom. The teacher quickly handed out the paper. The exam would last two hours and some of the expected questions came. I finished it almost forty-five minutes earlier. But since it was a rule not to collect the paper before the allotted（规定的）time. I had to sit till the teacher collected the paper. I checked my paper twice and corrected some of the mistakes in it. I started thinking about the place my friends and I had planned to go to after the exam. The time seemed to be endless. So I thought of drawing something on the paper and turned it overleaf. I was shocked to see that the page which I had supposed to be blank had four more questions on it which carried 20 marks and would take at least half an hour to complete. There were only 10 minutes left. I was so nervous that I could hardly write anything. They were the sub-questions（小题）of the last question. Suddenly our physics teacher came in and told all of us that in the last question, out of 6 sub-questions only 2 had to be solved. I felt very relieved.

From then on, I realized that my anxiousness and excitement could have cost me to lose 20 marks and decided never to make such a mistake again.

某工程，建设单位与甲施工单位按照《建设工程施工合同（示范文本）》签订了施工合同。经建设单位同意，甲施工单位选择了乙施工单位作为分包单位。在合同履行中，发生了如下事件。事件1：在合同约定的工程开工日前，建设单位收到甲施工单位报送的工程开工报审表后即予处理。建设单位考虑到施工许可证已获政府主管部门批准且甲施工单位的施工机具和施工人贵已经进场，便审核签认了工程开工报审表并通知了项目监理机构。事件2：在施工过程中，甲施工单位的资金出现困难，无法按分包合同约定支付乙施工单位工程款。乙施工单位向项目监理机构提出了支付申请。项目监理机构受理并征得建设单位同意后，即向乙施工单位签发了付款凭证。事件3：专业监理工程师在巡视中发现，乙施工单位施工的某部位存在质量隐患，专业监理工程师随即向甲施工单位签发了整改通知。甲施工单位回函称，建设单位已直接向乙施工单位付款，因而本单位对乙施工单位施工的工程质量不承担责任。事件4：甲施工单位向建设单位提交工程竣工验收报告后，建设单位于2012年9月20日组织勘察、设计、施工、监理等单位进行竣工验收，工程竣工验收通过，各单位分别签署了质量合格文件。建设单位于2012年3月办理了工程竣工备案。因使用需要，建设单位于2012年10月初要求乙施工单位按其示意图在已验收合格的承重墙上开车库门洞，并于2012年10月底正式将该工程投入使用。2014年2月该工程给水排水管道大量漏水，经监理单位组织检查，确认是因开车库门洞施工时破坏了承重结构所致。建设单位认为工程还在保修期，要求甲施工单位无偿修理。建设行政主管部门对责任单位进行了处罚。

根据《建设工程质量管理条例》（国务院令第279号），事件4中建设行政主管部门是否应对建设单位、监理单位、甲施工单位、乙施工单位进行处罚？说明理由。
