The combination of surveying and machine control technology helps Ängö Entreprenad to be on time, on specs and on budget

Ängö Entreprenad AB is a Swedish company specialized in earthworks for housing development, plumbing and drainage for residential areas. The company was founded back in the 1980’s by Dan Johansson. Today, the company employs approximately 25 people and a handful of independent contractors.

We meet the crew on a sunny Wednesday in September on a job site close to Gothenburg, Sweden. Five people work here full time on preparing the construction of four semi-detached houses. The project was started in the spring of 2020 and must be finished by autumn 2021.

“这在多种方面都充满挑战”。explains Mikael Persson who works as surveyor on the project.

The terrain is mountainous, cramped and located in the middle of an existing residential area, but until now everything goes according to the plan. We have good people and our machines equipped with the latest machine control technology, the Leica MCP80 control panel and the MC1 software. We also have poles, iCG70 T GNSS rovers and CC80 tablets from Leica Geosystems that allow us to make the stake-outs continuously so that our excavator operators know what to do all the time, thanks to the real-time available information on the machine control panel.

更快，更安全地静止不动

Entreprenad始于2009年的测量和利益，但并非2014年之前，该公司真正理解并经历了数字化的所有好处。如今，他们有六个配备了来自Leica Geosystems的机器控制解决方案，以及带有ICG70 T GNSS Rovers和Icon CC80现场平板电脑的两个测量线。这使得公司除了目前外包的测量服务外，还可以自己执行测量。

“We purchased the new iCG70 T rover and CC80 field tablet in 2009. Before that, we used the GS14 GNSS smart antenna and CS35 tablet controller from Leica Geosystems",explains Persson.“对我来说，新的Model ICG70 T，具有倾斜补偿是我的一个重大改进，他只能进行测量。我得到了一个非常精确的测量，甚至不必保持杆子。这个GNSS漫游者解决方案非常易于使用，当我不必在确切点握住杆子时，我可以更快，更安全。足以使两米长的碳杆的尖端放在测量点上，从而为我们节省了很多攀登。”

Sharing real-time data with the entire team

Persson用其设备测量的所有数据通过基于云的协作平台Leica Conx以及与其他GNSS Rover合作的同事直接与机器运营商共享。

This gives a very good overview and transparency of the construction site and what needs to be done and where, as Persson and his colleague supplement each other depending on who is closest to the actual location.

“我实际上不是数据专家，但是Leica Geosystems的解决方案是如此准确，合乎逻辑和用户友好，以至于我很容易学习如何使用它们。”珀森说。“Our surveying equipment communicates directly with the machine control solutions through ConX, as well as, we, who are responsible for the measurement can also communicate with each other through the cloud-based services. In addition, Leica Geosystems offers a platform called ‘myWorld’ that gives a really good overview of all the products that we have, when they need service and the subscriptions that are available. It sounds more complicated that it is,”确保珀森. “If there any questions, Leica Geosystems offers excellent support.”

通过机器控制独立工作，更有效

One of the excavators on site is a Volvo ECR235EL equipped with the latest technology from Leica Geosystems. The control panel mounted on the excavator is the MCP80 where the one-for-all MC1 software is running. Henrik Wirkstrøm is in charge of the excavators, and he has worked for Ängö Entreprenad for five years.

“I have been driving excavators for approximately 15 years, but I only came into contact with machine control five years ago, when I started here,”says Wirkstrøm.“通常，机器控制使我能够更加独立地工作，从而使我更加高效。我可以在网站上四处走动而无需等待利益，导致停机时间很少。我真的很喜欢旧的挖掘机系统，但是新的解决方案更有效。”

Wirkstrøm还将继续与倾斜旋转器传感器的直接通信以及面板的用户界面的设计。

“最大的区别是MC1现在与倾斜旋转器传感器通信，这是一个很大的优势，因为我99％的时间使用倾斜旋转器。面板更大也很高兴。更容易看到并按下右键。对我而言，最重要的是，Leica Geosystems的远程支持效果很好，如果我们遇到任何问题，它们总是在那里，”结论Wirkstrøm。
