Minimising environmental footprint by saving time and rework using machine control

作者：Karina Lumholt

在北大西洋的冰岛，苏格兰和挪威藏在北大西洋之间，一群18个火山群岛是约50,000人和许多绵羊的家。世界上最小的，有些人会说世界上的首都托尔沙文（Tórshavn）拥有该国几乎一半的年轻人口。

The Faroe Islands have a highly-developed infrastructure connecting the archipelago with bridges, roads, tunnels and subsea tunnels. The population growth, rise in tourism and large public transportation investments are causing the construction industry to boom.

Plan Sp/f is a 40-year-old construction company founded by Johannes Hellisdal. Today, father and son, Johannes and Dan Hellisdal, are working side by side in the company that employs approximately seven people, but this number can vary according to the season and the number of projects. Plan Sp/f has worked on road projects, roundabouts, site preparation, land development and parking lots in every part of the Faroe Islands and mainly in Tórshavn. The company is specialised in earthmoving activities and owns seven excavators whereof one is equipped withLeica iXE3 machine control solutionas well as aLeica iCON gps 70 Tfor stake-outs.

“我们的野心是在最小化环境足迹的同时有效地工作,” explains Johannes Hellisdal. “Machine control is a very targeted part of that strategy because we save a lot of costs, time and fuel by getting the job done right the first time.”

Using machine control is fairly new on the Faroe Islands, and both father and son acknowledge the many advantages. Plan Sp/f is right now working on a construction project in Tórshavn, preparing a site for the construction of 12 buildings that will host a total of 38 housings.

Dan Hellisdal explains the workflow, “We now work in a much more precise and faster way. I am using the Komatsu PC360 LC to dig down to the where the bedrock starts. My dad is sitting in the other excavator with the hammer, and we communicate with walkie-talkies. I can see directly on my machine control panel how much of the rock he must remove to get to the correct grade. Before we introduced machine control to our machine park, we spent a lot of time removing a lot of the bedrock, now we only remove what is necessary and that saves time, fuel and costs.”

As an added benefit Johannes Hellisdal explains there are still not so many heavy construction machines equipped with machine control on the Faroe Islands, hence, it is easy to rent out machines with machine control.

“We have water everywhere and the building grounds must be prepared with good drainage to keep the houses dry. We often have to pump the water away in order to continue working but we are so used to it that we do not even consider it to be a problem,丹·赫利斯达尔（Dan Hellisdal）解释说。

Machine control installer Kim Højland from Leica Geosystem installs and calibrates the iXE3 solution on the machine and explains the special preparations when installing machine control on a machine working in harsh weather.

“I need to install the iCG82 GNSS receiver inside the cabin in order to protect it from the weather, and the entire machine will receive a foam coating so that it is prepared for the Faroese conditions,” says Kim Højland as he finishes the calibration and loads the Faroese coordinate system into the Leica MC1 machine control software.

然后，该机器准备好运送并在法罗斯首都Tórshavn找到其新所有者。

Plan Sp/f’s ambition to work in a green and efficient way drove Dan and Johannes to order a new Komatsu 365 H Hybrid excavator, that reduces fuel consumption and consequently lower CO2 emissions. To get the job done efficiently without rework, thus fully minimise environmental footprint, the Hybrid excavator was pre-installed with Leica Geosystem’s iXE3 machine control solution directly from the dealer Scantruck in Denmark.
