某工程为10层钢筋混凝土框架结构。某施工企业现场项目部在自购钢筋进场之前,按要求向监理工程师提供了合格证,并经过见证取样复验合格。监理工程师同意该批钢筋进场使用。钢筋接头采用绑扎、电渣压力焊两种,在隐蔽工程验收检验钢筋焊接质量时,怀疑钢筋母材不合格。经过对该批钢筋重新检验,最终确认该批钢筋不合格。监理工程师随即发出不合格项目通知,要求施工单位拆除重做,同时报告业主。承包商认为本批钢筋使用前已经过监理工程师见证取样,复检合格,且同意使用。
问题：
1、为确保工程质量,在进行该项目质量控制过程中,该施工企业应采取哪些主要对策。
2、该钢筋工程质量验收内容有哪些?如何组织验收?
3、现场质量检查有哪些方法?
4、材料质量控制的要点和内容有哪些?
5、该工程的施工质量计划应由谁来主持编制?施工质量计划的内容有哪些?
