“BIM+GIS钢结构全生命周期管理平台”平台于2019年11月正式上线使用，平台由业务平台、交互平台、移动端三端组成。平台通过BIM技术、信息化技术、GIS技术、物联网技术、集成技术的应用，有效推进钢结构BIM全生命周期智能建造，实现“精品工程、智能丰台”的目标。
2、功能结构
应用了BIM技术、GIS技术、信息化管理等技术于钢结构项目管理中，包括展示平台、业务平台、移动端三部分组成应用重点如下：
(1)实现基于BIM模型查看任意构件设计管理、深化设计、预制加工、物流运输、现场管理、交验管理构件的全生命周期信息，辅助项目管理，直观将移动端、两家业务系统采集的数据直观进行展示。
(2)实现了GIS技术、BIM技术与智慧工地融合能够在GIS+BIM场景中随时随地的查看现场智慧工地如监控设备、环境监测、劳务数据、塔吊数据、基坑监测点数据、大体积混凝土测温数据等均与场景对应实现位置信息3维一体。
(3)实现了智慧工厂数据到项目系统中数据的无缝衔接，平台通过接口成功获取了两件钢结构工厂供应商生产阶段数据，实现数据的无缝衔接，数据同步。
