本项目采用固定总价合同,施工难度之大在全国矿山环境生态恢复治理工程中尚属罕见,没有可供借鉴的成功经验,项目实施过程中存在着诸多的风险。施工过程中通过分项工程间工作内容的合理调整,根据“动态设计、信息化施工”的原则,通过施工方法的变更,不仅解决了前期投标工作中因经验不足而带来的问题,而且规避了近100 m高空锚杆施工所带来的困难和安全风险,确保了工程质量满足要求,工程费用不突破预算。实现了安全、坡稳、山绿、如期、投资总额不突破五大目标。
The project uses a fixed total price contract. It is rare for the construction difficulty in the national mine environment ecological restoration and treatment project. There is no successful experience for reference. There are many risks in the project implementation. Through the reasonable adjustment of the contents of the work among the sub-projects in the construction process and through the alteration of the construction methods according to the principle of “dynamic design and informatization construction”, not only the problems brought by the lack of experience in the earlier bidding work have been solved, But also avoids the difficulties and safety risks brought by the construction of anchors near the height of nearly 100 m to ensure that the project quality meets the requirements and the construction cost does not exceed the budget. Achieved a safe, stable, mountain green, schedule, the total investment does not break five goals.
