Building the longest road in Greenland

Author:Karina Lumholt

Qaqortoq的人口少于3,000，是格陵兰南部居民最多的城市。也是第四大城市在岛上。

作为格陵兰的所有人口稠密的地方，Qaqortoq均未通过道路连接到其他地方。该市由直升机连接到位于90公里外的Narsuaq机场。这些直升机一次只能运送9人。到达Qaqortoq的唯一其他方法是乘船，只要温暖，才能做到这一点。

Transport to and from Qaqortoq is challenging and expensive due to:

• 远距离
• Severe climate
• Difficult terrain

实际上，建造新机场的价格要比将城镇与道路联系起来便宜。一个新的机场对于经济增长，提供就业并鼓励旅游业至关重要，这在格陵兰经济中起着越来越多的作用。

2014年，格陵兰议会，InatsisArtut, granted funding for the construction of a6.2公里通往未来的机场。QaqortoqEntreprenørforretning赢得了合同，并致力于道路的建设。

一个冒险的

格陵兰的运输系统确实是一次冒险。没有道路，没有铁路 - 自然规则。从历史上看，主要的运输方式是在夏季乘船和冬季狗雪橇。

整个国家总共只有150公里的道路，其中只有60公里。Qaqortoq的6.2公里公路是最长的单路自第二次世界大战以来已经建立了。

Constructing a road in southern Greenland is extremely difficult and expensive. There are no construction materials since the subsoil only consists of rocky mountainous terrain, which must first be blasted and then crushed in order for it to be used as foundation for the road.

“我们使用了35吨炸药来爆炸70,000平方米。”explains Lars Motzfeldt Jensen, who is one of the two owners of Qaqortoq Entreprenørforretning.

恶劣的冬季气候

Qaqortoq Entreprenørforretning already had a Leica iCON excavate 2D solution installed on its machines. The company recently decided, though, to upgrade to aLeica iCON excavate 3D solutionand buy a second one for its new Hitachi 350 excavator.

The solutions from Leica Geosystems have工作无障碍even in the harsh climate conditions of the arctic winter with temperatures of -25 °C after dark.

However, there are certain challenges in Greenland as Per Eriksen from Leica Geosystems explains:“500年我tres away from the centre of Qaqortoq, we lose the telephone connection. This makes calibration and service of the solutions very difficult. We used radio repeater stations in order to transmit the correction signals from the reference station to the GNSS antennae on the machines.”

According to Jensen, the 3D solutions have节省了很多时间和成本。

建造一条道路现在更有趣

“If we had known that we would save that much time and cost, we would certainly have bought a 3D solution for our driller as well,”詹森说。

A positive side effect of using machine control has been the increased job satisfaction for the machine operators.

“当我们使用3D设备时，建造一条道路非常有趣，” says Nikki Davidsen who works as machine excavator operator for Qaqortoq Entreprenørforretning.

准备建造机场

When the new airport is approved for construction and starts, Qaqortoq Entreprenørforretning is ready for the job. Jensen explains the project would benefit from using Leica Geosystems 3D solutions.

“我们是格陵兰岛配备最佳的建筑公司，如果格陵兰议会决定建造机场，我们绝对准备完成这项任务，”詹森得出结论。
