通过对某水电站扩机工程EPC合同执行过程中发现的部分税务、支付及调差等具体问题进行分析,提出相关解决对策,意在提醒后续项目合同签订过程中对类似问题事先加以考虑,尽量避免同类问题的再次出现,为工程的顺利实施提供更为良好的合同基础。 By analyzing some specific problems such as tax, payment and adjustment found during the EPC contract of some hydropower station expansion project, some countermeasures are put forward to remind the follow-up project that the similar problems should be considered in advance and avoid as much as possible The recurrence of similar problems provides a better contractual basis for the smooth implementation of the project.
