某建设单位和施工单位按照《建设工程施工合同（示范文本）》签订了城市道路主干道施工合同，合同中约定：建筑材料由建设单位提供：由于非施工单位原因造成的停工，机械补偿费为200元/台班，人工补偿费为50元/日工；总工期为120天；竣工时间提前奖励为3000元/天，误期损失赔偿费为5000元/天： 

事件一：挖方段遇到了工程地质勘探报告没有揭示的岩石层，破碎、移除拖延了3d时间（自由时差0天，每日45工日，60台班）； 

事件二：工程拖延致使路基施工进入雨期，连续降雨使土壤含水量过大，无法进行压实作业，因此耽误了5d工期（每日30工日，45台班，非关键线路，自由时差10天）。 

事件三：①由于建设单位要求对道路连接线工作的施工图纸进行修改，致使该项工作停工3天（自由时差5天，每停一天影响30工日，10台班）；②由于机械租赁单位调度的原因，施工机械未能按时进场，使跨线人行天桥工作的施工暂停5天（自由时差2天，每停一天影响40工日，l0台班）；③由于建设单位负责供应的材料未能按计划到场，底基层工作停工6天（自由时差5天，每停一天影响20工日，5台班）。 

事件四：在工程竣工验收时，为了鉴定某个关键构件的质量，总监理工程师建议采用试验方法进行检验，施工单位要求建设单位承担该项试验的费用。

分析施工单位应该获得工期提前奖励，还是应该支付误期损失赔偿费。金额是多少？
