  京哈高速公路是中国“两纵两横及三条重要路段”国道主干线路网规划中建成的第一条路,是连接哈尔滨和长春的快速通道。本项目起点位于已建长春绕城高速公路西北环(即京哈高速公路长春过境段)后存金堡,通过小西屯枢纽互通立交与长春市绕城高速东南环连接,设计终点为米沙子服务区,总长度10.615公里。本项目为对既有京哈高速公路进行四车道改八车道扩建工程。
 
  本工区为既有京哈高速公路改扩建工程,现有交通流量大,施工期间不能全封闭交通,仅能半幅封闭,施工期间需保通,交通组织、安全管理难度大,施工组织尤其是小西屯互通区施工组织协调难度大。路基工程挖方利用率低、弃方量大,填方借方量大,大量填土需掺灰改良。新老路结合部位差异性沉降控制要求高。
 
  在本项目BIM应用中,使用CIVIL3D、REVIT、DYNEMO等BIM软件进行参数化建模,直观与高效地展现道桥样式及周边场景。基于BIM模型对土方调配、钢箱梁施工、桥梁加宽、交通导改等重要施工方案进行可视化方案比选及模拟。形象的展示出整个施工过程,并对施工过程进行进度、成本5D分析。协助各项决策,以降低甚至避免工程中可能发生的误解、冲突、错误、浪费与风险等。
