总计仅有四分之一英里长,172美元-million AirTrain extension significantly enhanced connectivity at San Francisco International Airport. Carried out over 40 months using progressive design-build delivery, the project extended the existing electric people-mover system to the airport’s long-term parking garage, surface parking lots and ground transportation staging areas. In addition, new stations were provided at the garage and at the newly constructed Grand Hyatt hotel. The result is easier access for travelers, less roadway congestion and more clean-energy transportation around the airport. Incorporating the garage into the AirTrain network, for example, replaces a shuttle bus connection that generated 600,000 miles of trips annually.

飞机场construction projects are inherently complex, as even the slightest issue can disrupt finely tuned ground operations. From the outset, the project team coordinated with airport officials and rental car facility management to shape the extension’s design elements and account for all potential issues as concepts turned into buildable specifications. A cloud-based BIM management and collaboration tool helped improve efficiency and clash-detection as the design evolved, providing the entire team with near instant access to the most up to date design information.

该协作持续到施工正在进行中，通过定期沟通协调活动，计划车道关闭，在轨道停机期间增加公交车，并提供对施工活动发生的高安全保护区域。

随着酒店和新的飞机站共享重叠施工足迹，该项目团队与酒店承建商密切合作，计划分期，账户和材料交付，以支持两个项目的持续运行，并有目的地与酒店开设航空站18luck官网2019年10月。在建设的最后几个月，超过15个分包商在酒店站工作了一天和晚上，将三个月的工作压缩到30天内。

协作和合理规划有助于将项目团队定位以处理意外问题。当原始结构钢制造商无法按照繁忙市场时按时提供所需的组件，团队争先恐后地查找五个可以完成工作的制造商。然而，随着枢轴将施工时间表延长五个半月，恢复供应链可靠性具有其成本。18luck.cub使用钢材制造商和重新开始的勃起计划，将每周协调会议，质量控制和优先级核查询，团队恢复超过一半的损失时间。

Covid-19同样测试了项目团队的弹性。控制病毒传播的努力包括社会疏远，最小化船员暴露，零容忍政策，在生病时工作，并要求工人在离开工作后改变衣服。因此，该项目录得没有Covid-19案例，补充了近377,000个员工的损失事故的显着安全成就。

飞机有助于机场的净零能源目标。这两个车站都设计为利兹金标准，具有用于水效率，能源性能，健康材料和资源的元素，以及增强的室内环境质量。
