使铁路资产捕捉什么ickly and safely
Complete rail asset capture, without disrupting construction in a matter of weeks
项目：捕获Gotthard Base隧道的所有基础架构
客户：Grunder Ingenieure AG
产品：Leica Pegasus：两个
OBJECTIVE: Grunder Ingenieure AG was contracted to deliver a complete inventory and as built documentation of the Gotthard Base Tunnel without disrupting the ongoing construction
Grunder Ingenieure AG签订了合同，以提供完整的库存和Gotthard Base Tunnel的构建文件。使用Leica Pegasus：两个他们能够在短短几周内有效地捕获整个项目，而不会破坏正在进行的建筑，从而使所有工作利益相关者受益。该公司选择了Leica Pegasus：两个用于捕获新建的开放式轨道的基础架构安全有效地使工程师能够与最准确的表示形式合作。
当Gotthard Base隧道于2016年6月作为通过阿尔卑斯山（NRLA）的新铁路链接的一部分正式开放时，建筑项目20年以上的时间为98亿瑞士法郎，生产了世界上最长，最深层的交通隧道。该隧道长57公里，岩石覆盖量为2300米，增加了整个瑞士阿尔卑斯山的总运输能力，同时将北欧和南欧之间的乘客旅行时间减少了一小时。该路线的梯度最小和宽阔的曲线，在海拔550 m的情况下，这条路线也是一个平坦的低级旅程。整个隧道系统总计152公里，再加上近50公里的新内置室外轨道。
When Grunder Ingenieure AG, a leading Swiss engineering firm specialising in rail surveys and long-time user of Leica Geosystems solutions, was sub-contracted by the Alptransit Gotthard AG, the firm knew it would be a challenging task but one for the history books. One of the main tasks, before the tracks open for the test operation, was to capture all the infrastructure of the tunnel for as-built documentation.
"There are several stakeholders working on the overall project, and we were tasked with registering the entire infrastructure to collect for the infrastructure database of the Swiss Federal Railways. All these users can now access this information," said Gilbert Roulier, Grunder’s director of imagining, laser scanning and mobile mapping. "Entering the under-construction tunnel and outdoor tracks also presented organising challenges that we needed to account for with our engineers and surveying instruments."
The firm selected the Leica Pegasus:Two to capture the entire infrastructure of the new built open tracks safely and efficiently. In combination with Leica Geosystems total stations, Grunder was able to provide a complete database of 3D imagery and point clouds covering the rails, signage, posts, electrical lines, and further installations and structural elements.
