向家坝水电站右岸进厂交通洞工程因受征地移民的影响,开工时间推迟,导致与二区混凝土系统和上坝交通洞开挖形成立体交叉施工,工效降低、工期延长、成本增长。为此,施工单位提出了索赔。通过实践认为,要做好索赔工作应从索赔条款的订立和熟悉条款内容、索赔资料的日常收集和整理、索赔意向书的编制与提交三个方面入手。 Due to the impact of land acquisition and resettlement, the start-up time of the traffic tunnel on the right bank of Xiangjiaba Hydropower Station has been delayed due to land acquisition and relocation. As a result, the three-dimensional cross-excavation works have been conducted with excavation of traffic tunnels in the Second District and the upper dam, reducing work efficiency, extending construction period and increasing costs. To this end, the construction unit submitted a claim. Through practice, we should start with the formulation of claim clauses and familiarity with the content of the clauses, the routine collection and collation of claim information and the preparation and submission of the claim letter of intent.
