(一)

[背景资料]

某办公楼由15层主楼和3层辅楼组成。施工单位(乙方)与业主(甲方)签订了承建该办公楼施工合同，合同工期为350天。合同约定工期每提前(或拖后)1天奖励(或惩罚款)2000元。乙方提交了粗略的施工网络进度计划，并得到甲方的批准。该网络进度计划如图1所示。

施工过程中发生如下事件。

事件1：在基坑开挖后，发现局部有软土层，乙方配合地质复查，配合用工12个工日。根据批准基地处理方案，乙方增加直接费5万元。因基地复查使基础施工工期延长5天，人工窝工15个工日。

事件2：辅楼施工时，甲方提出修改设计要求，乙方按设计变更要求拆除了部分已完工程，重新施工。因此造成增加用工25个工日，材料费、机械台班费计2万元，辅楼施工拖延8天。

事件3：在主楼结构施工中，因施工机械故障，造成工人窝工10个工日，该工作工期延长4天。

事件4：由于工期较紧，经甲方同意，乙方在装饰工程时采取了加快施工的技术措施，使得该工作缩短了10天，该项技术措施费0.5万元。

该工程实际工期为多少天可得到的工期补偿为多少天工期奖(罚)款是多少
