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.

“这一直以多种方式具有挑战性”，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.

放弃得更快，更安全

Ängöntreprenad于2009年开始衡量和股份，但在公司真正理解并经历了越来越多的富有利益之前，它不是在2014年之前。今天，他们的挖掘机有六个配备了来自Leica Geosyystems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杆。这允许该公司除了他们目前外包的测量服务外，还可以自己进行测量。

“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.“新型号ICG70 T，倾斜补偿是我的重大改进，谁只适用于测量。我得到一个完美的精确测量，甚至不必直接握住杆子。这个GNSS流浪者solution is very easy to use, and I can stake out much faster and safer, when I don’t have to hold the pole vertical at the exact point. It’s enough that the tip of the two-meter long carbon pole is placed at the measuring point, saving us a lot of climbing”.

Sharing real-time data with the entire team

所有数据都与其设备的所有数据都与机器运营商通过Leica Conx，一个基于云的协作平台以及与其他GNSS Rover合作的同事共享。

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.

“我实际上不是一个数据专家，但Leica Geosystems的解决方案是如此准确，逻辑和用户友好的解决方案，即我很容易学习如何使用它们，”波斯森说。“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,”assures Persson. “If there any questions, Leica Geosystems offers excellent support.”

Working independently and more efficient with machine control

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.“Machine control has in general allowed me to work more independently and thereby made me more efficient. I can move around on the site without waiting for stake-out, resulting in very little downtime. I really liked the old excavator system, but the new solutions are more efficient.”

Wirkstrøm还继续与倾斜转子传感器直接连通的优点和面板的用户界面的设计。

“最大的区别是MC1现在与倾斜转子传感器通信，这是一个很大的优势，因为我使用倾斜旋转器99％的时间。面板更大，这也很好。更容易看到并按下右键。对我来说最重要的是，如果我们遇到任何问题，Leica Geosystems的远程支持很好地运作良好，并且在那里，他们总是在那里，“总结了Wirkstrøm。
