Beyond 3D machine control: An integrated piling solution

作者：Reka Vasszi

The use of pile dwellings and deep foundation techniques to construct houses around the Alps date back to 5000 BC. Prehistoric settlements were built on wooden piles on the edges of lakes, rivers or wetlands. Only in Switzerland, there are 56 archaeological sites where these settlements and ancient construction techniques are exceptionally well-preserved.

Since prehistory, the technology has evolved, tools and machines for piling became larger, more efficient thanks to automation and positioning technology. Deep foundations are vital in many construction projects to strengthen the soil that will support the weight load of the building erected on top of it. When ground conditions are wet, or the project is planned above water, driven piles are crucial for the foundation of a new building.

这是瑞士建筑公司的堆积专业知识Birchmeier Spezialtiefbau AG时，在为苏黎世湖岸的水上警察的新建筑物的基础上工作时，就派上用场。

将船屋转换为防水警察局

苏黎世的水上警察确保该地区的24小时救援服务，寻找水下的人和物体，保护水免受油和化学物质的影响，管理船上摊位并维护港口。现有的建筑物和60年前建造的船屋将在2022年让位于当代的新建筑中，水警察和环境犯罪专家团体可以共同努力。

The new water police station is located on a prominent lakeside with neighbouring protected historic buildings from the 1930s. Therefore, the municipality initiated an architecture competition to find the best design that matches the neighbouring historical buildings, sustainable and fits the functional requirements.

The jury was impressed by the project called "Coray" with its very clear and compact structure, including a boathouse, offices and a helicopter landing pad on top of the building. Due to the wet ground and weight load of the planned building, Birchmeier Spezialtiefbau AG was contracted to secure the deep foundation of the site.

Integrated technology is key to prepare for the job

Choosing pile foundations were ideal in the case of the new water police station. The waterside building is constructed to allow water underneath for easy access to the boats. In order to start the construction project, more than 150 piles were required to stabilise the ground.

Andreas Gassmann担任Foremen和Michael Fuchs担任Birchmeier Spezialtiefbau Ag的堆操作员，确保每个堆在正确的时间位于正确的位置。

Fuchs is working as pile operator at Birchmeier Spezialtiefbau AG for 3 years now. He is very fortunate to work on this project as he has the most comfortable seat and the best view over the lake of Zürich from his Liebherr 355 piling rig. Each morning together with Gassmann, they start with site inspection and overview of the daily tasks.

一旦Fuchs与团队保持一致，他打开了Liebherr Piler与latest Leica iCON iRP3 3D machine control solution. For accurate positioning, he checks the connection to the correction service is on as always. The corrections are needed for precise location and are handled by the machine control panel to the entire system. After the connection is checked, he loads the latest 3D model directly from the office to the machine control panel via the cloud solution,Leica Conx.

机器控制技术，精确的位置数据以及与办公室工作人员通过云的无缝集成使现场团队的每日工作变得更加容易，更快，更高效。

Saving 5 minutes per pile with 3D machine control

While the operator finishes his coffee in the cab, the 3D plan is loaded to the machine control solution, location data is secured, and the piler machine is ready to go. Since Fuchs is working with 3D machine control technology, he does not need an additional team member on-site to stake out and check the exact location of the piles.

"Before using machine control, we worked with a surveying firm to locate where the piles need to be driven into the ground,"says Fuchs. "If the markings on the site were removed or disappeared, we had to wait again to recreate those points. With machine control, we always have an updated 3D plan on the panel that automatically guides me to the right location with centimeter accuracy."

通过使用3D机器控制，不仅桩的位置是准确的，而且不需要返工或等待出现。因此，Birchmeier Spezialtiefbau AG可以节省现场一个人的费用。

“有了3D系统，我可以每堆至少节省5分钟，这在一天结束时花了很多20块，”reports Fuchs. "但是，通过机器控制，它也变得更加舒适，更容易，更安全。当使用如此大的机器和重堆工作时，周围人民的安全非常重要。现在，我可以相信机器控制的准确性可以指导桩毛的位置，我可以更多地关注其他方面，例如压力较小的安全性。”

Measure, check and verify with GNSS Smart Antenna

Swiss precision means: measure, check and verify. In the meantime, Fuchs is working with the piling machine; Gassmann double checks if each pile is in the right location with hisLeica Icon GPS 70 GNSS智能天线根据悬挂在他的小野外办公室墙上的计划。

"My favourite product is the gps rover,"says the foremen.“我在GPS控制器上的3D计划与FUCHS在他的机器控制面板上的计划相同。我检查并验证地面上的每个堆，并越过计划中准备好的堆。”

In his previous role working in building construction, he used the Leica iCON gps rovers for quick and precise stakeouts. Since the team is working with 3D machine control technology, Gassmann does not need to stake out the location of the piles for the operator anymore; they can trust in the 3D system's accuracy.

"Working with machine control means time savings and accuracy, which automatically leads to costs savings，”加斯曼说。"I love both products: the gps and machine control; it helps us to get the job done right for the first time,"总结工头。
