某安装公司分包一商务楼(1~5层为商场,6~30层为办公楼)的变配电工程,工程的主要设备(三相干式电力变压器、手车式开关柜和抽屉式配电柜)由业主采购,设备已运抵施工现场。其他设备、材料由安装公司采购,合同工期60d,并约定提前1d,奖励5万元人民币,延迟1d,罚款5万元人民币。
安装公司项目部进场后,依据合同、施工图、验收规范及总承包的进度计划,编制了变配电工程的施工方案、进度计划,劳动力计划和计划费用。项目部施工准备工作用去了5d。当正式施工时,因商场需提前送电,业主要求变配电工程提前5d竣工。项目部按工作持续时间及计划费用(见下表)分析,在关键工作上,以最小的赶工增加费用,在试验调整工作前赶出了5d。
进人试验调整工作时,发现有2台变压器线圈因施工中保管不当受潮,干燥处理用去了3d,并增加费用3万元。项目部又赶工3d,变配电工程最终按业主要求提前5d竣工,验收合格后,资料整理齐全,准备归档。
项目部在哪几项工作上赶工了?分别列出其赶工天数和增加的费用。
