From the laser scanner to office in near real time

To move gas safely and reliably to the end consumer, the Netherlands has a high-quality gas transportation network. For undisturbed gas delivery, it is important that the network is always in excellent condition. Therefore, Gasunie, a European transmission system operator that provides the transport of natural and green gas in the Netherlands and the northern part of Germany, performs daily management and maintenance work to the main gas transportation network and to the regional gas transportation network.

荷兰的网络包括：

• 12,500公里的管道
• 3,000 valve schedules
• 80 measuring and control stations
• 1,000燃气接收站
• 13个压缩机站。

在执行维护和更换期间，向最终客户的天然气传递。因此，造成尽可能少的不便是一个挑战。因此，Gasunie首先对管道进行了详细的设计。根据设计，新组件是预制的，因此在现场的安装工作需要尽可能少的时间。

Gasunie结合了多个Leica GeoSystems解决方案，这些解决方案使激光扫描数据直接从现场到客户和分包商，现在可以通过重新设计的Leica HDS工作流程节省时间和金钱。在整合Leica Geosystems解决方案之前，提供了很长时间的时间花费了很长时间 - 现在，在24小时内准备好了一个精确的AS构建模型。

The mix and match solution

To accelerate and improve the overall process, a pilot has been conducted in combination with Advin advisory and engineering firm using 3D laser scanning. The working process has been reviewed and innovative steps have been taken in the data processing by using Leica JetStream software for simplified point cloud access and ultra-high speed rendering.

After the design, prefabrication and transport of the parts, the new installation is assembled on site. This installation is checked using a Leica Viva GS16 GNSS Smart Antenna and a Leica Nova MS60 MultiStation linked to a CS35 tablet computer with Leica Captivate software. Inside the Captivate software, the Inspect Surface app looks at whether there are deviations between model and as-built situation and will determine whether the new situation meets the requirements of Gasunie.

整个安装都用多阶段或Leica ScanStation P40映射。该测量是在现场处理和检查的，并通过CS35上的移动4G连接直接上传到Jetstream Server。

“ Leica Geosystems系统开发的系统非常适合以优化我们的工作流程。从设计到建筑的最后阶段，这种工作方法减少了时间，因此可以节省金钱。特别是，在施工阶段，保存的点云作为资产信息可能会在多年后变得有用。此外，我们还能够扫描棕地资产，并将其转换为具有新（未来）功能的真实3D资产信息。” Gasunie的高级管道工程师Sijbrand Stratingh说。

Benefiting from the industry - leading point cloud project server

The use of JetStream server has a number of important advantages. The data is centrally available in the cloud so engineers involved can directly access the data. Because the point cloud is available online, Gasunie can also access this data directly via TruView Global and/ or JetStream viewer. The firm can then use the point cloud for discussions using digital reality, making better informed decisions if needed.

聪明的点云技术在地方紧密相联的ws data to be viewed and used without delay via an online connection without missing any detail. There is only one version of the point cloud and, therefore, only one backup has to be made. Unnecessary copies belong to the past.

选定的选择必须正确

多亏了Leica Geosystems的结合解决方案，使用点云生成的3D设计可以无缝地适应较好的情况。Gasunie不再需要从头开始创建全新的刊物图纸。3D模型的更新就足够了。

“We always strive to work with state-of-the-art hardware and software that can provide the best solution to our customer. The choice for Leica Geosystems, a reliable supplier of highend equipment, was a clear one. When we really have a problem, Leica Geosystems immediately provides a solution,” said Jeffrey den Ridder, surveyor at Advin. “After measuring the project, the excavated pit is replenished immediately with soil. The measurement must therefore be carried out as efficiently as possible and there is certainly no time for delays caused by defective equipment or technical failures.”

After completing these first tests, Gasunie is very positive about the workflow through 3D laser scanning and instant online sharing of data through Jetstream in the cloud with Autodesk® AutoCAD® Plant 3D.
