【背景材料】
某施工单位承建一南方沿海城市的大型体育馆机电安装工程。合同工期为10个月，于 2004年11月10日开工，2005年9月10日竣工。
该工程的特点是各类动力设备包括冷冻机组、水泵、集中空调机组、变配电装置等，均布置在有通风设施和排水设施的地下室。
由于南方沿海空气湿度高、昼夜温差大，夏天地下室结露严重，给焊接、电气调试、油漆、保温等作业的施工质量控制带来困难。
通风与空调系统的风管设计工作压力为1 000Pa。项目部决定风管及部件在场外加工。
项目部制定的施工进度计划中，施工高峰期在6月～8月，正值高温季节。根据地下宣的气候条件和比赛大厅高空作业多的特点，需制订针对性施工技术措施，编制质检计划和重点部位的质量预控方案等，使工程施工顺利进行，确保工程质量。
在施工过程中，由于个别班组抢工期，在管理上出现工序质量失控，致使在试车阶段发生施工质量问题，如通风与空调系统进行单机和联动试车时，有两台风机出现振动大、噪声大、电动机端部发热等异常现象。经调查发现，风机的钢垫铁有移位和松动，电动机与风机的联轴器同轴度超差。
【问题】
1．针对环境条件，应制订的主要施工技术措施有哪些？
2．为保证地下室管道焊接质量，针对环境条件编制的质量预控方案包括哪些内容？
3．按风机安装质量问题调查结果，分别指出发生质量问题可能的主要原因。
4．风管及部件进场时应做什么检验？。风管系统安装完毕后要做什么检验？
5．变配电装置进入调试阶段，因环境湿度大，会造成调试时测试不准或不能做试验时，在管理上应采取哪些措施？

根据TSGR7001-2004《压力容器定期检验规则》的规定，说明全面检验压力容器强度校核时如何选取强度校核用的壁厚？

TSG R7001-2004《压力容器定期检验规则》列出了哪些安全状况等级划分的项目？
