Laser Scanning makes its mark in Melbourne’s largest rail project

案例分析

Author: Tamara Stakic, Marketing Manager - Leica Geosystems, Australasia

奥斯帕特土地调查澳大利亚(Auspat) is no stranger to servicing large multi-faceted infrastructure projects. The Australian engineering and infrastructure company has been engaged to provide surveying solutions on some of the largest and most significant infrastructure projects in Australia - from the M7 in Sydney, to Eastlink in Melbourne, the Gateway Duplication in Brisbane, the Superway in Adelaide and more recently Melbourne’s Metro Tunnel and Westgate Tunnel projects.

为了在该国最大的基础设施项目上提供测量和空间解决方案,AUSPAT认识到数字和空间技术创新会增加对客户的价值,提高质量并提高项目交付的生产率。利用最新技术使Auspat可以为其客户提供最佳的质量数据和服务。


Laying the foundation

自1970年代建造的城市循环以来,Metro Tunnel项目是澳大利亚墨尔本最大的铁路项目。它涉及建造双九公里的铁路隧道和从墨尔本北部到CBD以南的域区的五个地下车站。

Auspat has been engaged on the project since 2018 and have been involved throughout many phases - from diaphragm wall (D-Wall) construction (Arden Station), excavation and early groundworks (station boxes and portals), tunnel entrance excavation, and station construction (Arden and Anzac stations).

团队最初部署了Leica Nova TS60Nova MS50多阶段要在站点站点和门户网站上建立控制网络。目的是为这些站点建立主要的调查控制网络。对于AUSPAT的团队,必须使用可靠,准确的控制网络,并使用他们成功地在网站周围进行遍历的Leica Geosystems总站。bob apple

在Arden上还使用了MS50多恒星来扫描和监视散装土方工程,以计算每日量并确保进行车站盒进行设计。


眼见为实



When commencing structural work and verification of design, theLeica ScanStation P40调查级激光扫描仪已部署。扫描仪P40扫描仪允许团队捕获网站的快速扫描,轻松注册扫描Leica Cyclone寄存器(点云注册办公室软件)并导出用于使用的数据Leica Cyclone 3dr,提取线路工作和表面。

Cyclone 3DR还用于使用点云数据和热图评估设计与设计的潜在偏差。

“我们的客户价值的视觉的热图,3 d数据deliverables and 3D models because it is easy to comprehend and it visually helps to determine and show potential deviations in a complex environment. Also, the point cloud data is highly accurate, and this quality gives the team at Auspat that extra confidence to deliver the perfect data to the client. This visualisation makes it easy for our clients to compare the built structures to the design and to identify any deviations that must be addressed. Another benefit is that we can export our scans in multiple formats that can be used by most of the CAD packages our clients and designers use,” said Mal Friel, senior surveyor Auspat.

扫描仪P40激光扫描仪的一个有用应用是我们可以在使用传统方法的具有挑战性和耗时的领域收集数据。

“这些只是我们可以向客户提供的其他一些增值。一旦他们看到了扫描仪可以产生的细节水平,这对他们来说是一个简单的决定。在三分钟的扫描中,我们可以准确地提供他们在简短甚至其他我们最初没有捕获的数据中所需的内容。这节省了团队多个站点访问。”弗里尔解释说。


向前扫描

采用激光扫描技术不仅帮助Auspat实现了可交付成果,而且还帮助他们完成了项目截止日期。扫描技术使Auspat可以在每个设置的五到10分钟内完成扫描,只有一个人需要操作扫描仪,而不会破坏现场其他项目团队。

奥斯帕特(Auspat)一​​直是Scanstation P40的骄傲所有者,已有12个月以上,但没有回头。随着在他们的车队中增加扫描仪,奥斯帕特(Auspat)已扩展为其他服务,并能够为客户增加价值。使用扫描仪P40扫描仪,Auspat现在可以扫描大面积并提取功能,或者比传统功能调查更快,更快地创建3D DTM。

弗里尔说:“具有扫描能力使我们能够在诸如铁路走廊和高速公路等复杂环境中进行调查,而无需循环或车道封闭,从而为客户提供了相当大的效率。”

扫描技术的采用使Auspat提高了效率,反过来,他们能够通过咨询和设计机构进行更多功能调查工作。

“More and more projects are asking for point clouds and clients are highly impressed with the data they are receiving, which greatly increases the likelihood of their repeat business.” said Friel.

扫描仪P40由于熟悉的界面和轻松采用了团队而赢得了AUSPAT。弗里尔说,“扫描仪上的“切除”和“遍历”功能之类的程序使我们对数据具有增加信心。”

This meant that with the support and hands-on training from Leica Geosystems Australia distributorC.R.肯尼迪扫描专家Sam Hesper,奥斯帕特(Auspat)的团队能够使他们的扫描项目启动并迅速运行,并充满信心地,支持只是一个电话。

We asked Mal if he had any advice for his peers or other companies thinking about adopting scanning technology. “Spend time understanding the client brief and focus on what’s most important to them. Don’t confuse the client with unnecessary data, present the most beneficial and useful deliverable that addresses the brief.”


奥斯帕特的下一步是什么?

“我们已经看到,从预制码等扫描和无人机服务的需求增加,验证桥梁梁和检查模具,到大型的民用基础设施项目,要求我们捕获航空图像和批量的土方工程。

‘我们希望继续探索地理空间技术并扩大我们的能力。让Leica Geosystems和C.R Kennedy作为合作伙伴使我们可以访问硬件和软件的最新进展。

This ensures we will be able to keep offering our clients cutting edge solutions to their survey requirements,” said Friel.
