Building roads in Norway with machine control solutions

Author:Karina Lumholt

长距离，高山和恶劣的气候使挪威的道路建设成为严重的挑战。然而，挪威已经建立了良好的道路网络，并向挪威运输基础设施进行了大量投资。挪威公共道路管理局，Statens Vegvesen和Nye Veier A/S目前正在研究18 road projects throughout Norwayto ensure safer roads that can meet the requirements of the ever-increasing road traffic.

Long-time customer of Leica Geosystems’ Machine Control Division,Hæhre A/S，赢得了两项最大的合同。

1. The43公里expansion of the E6 motorway between Kolomoen and Arnkvern. The contract sum is25 million Euros, and the project is expected to be finished in December 2020; and
2. The18-km motorwayon E18 between Rugtved and Dørdal. The contract is worth25 million Eurosand is expected to be finished in December 2019.

Established in 1974, Hæhre A/S is one of the largest construction companies in Norway. It employs a total of 2,700 employees, hereof 1,800 employees in the construction division.

Hæhre A/S has won the contracts because they were best on five out of six criteria:

• Price
• 环境问题
• 安全与健康
• Technical solutions
• Implementation.

Hæhre is one of Leica Geosystems’ Machine Control Division biggest customers with more than300 construction machines equipped with machine control solutions. The majority of these machines are excavators, drillers for blasting, and soil compactors.

Kim Eirik uses Leica ConX to synchronise and share data files with machines on site.

On Hæhre’s site office in Hamar, Kim Eirik Hagen works as data engineer and usesLeica iCON officeto prepare the design files that he sends to the machines on the job site.

“I use ConX to synchronise with the machines on site to make sure that everybody is working with the latest updated files,”Eirik explains.

Machine control solutions built for the heavy construction industry

Blast drill holes made according to the Leica iCON iRD3 model

在Stathelle的工作现场，挖掘机挖到岩石表面。遵循数字定义的钻孔图案，然后使用钻井钻机将孔钻入岩石中进行爆炸。

TheLeica MCP80panel shows the split screen functionality of the drill pattern and the bullseye guidance of the tool point.

On another place on the job site, machine operator John Stakke is working with a FlexiRoc T35 drilling holes and preparing for blasting rock away to make space for a wider road. The FlexiRoc T35 does not have a cabin – Stakke is standing outside the machine remotely controlling the drilling process while closely following the drill pattern on the Leica MCP80 machine control panel.

The iCON iRD3 solution used on a drill rig without a cabin.

The Leica Geosystems machine control panels,专为重型建筑行业设计, withstand the harsh conditions and extreme temperatures on construction sites.

Using ConX for compaction report generation

Using the ConX reporting module to generate compaction reports for as-built documentation.

After the blasting, the debris rock is used as road fill. The soil compactors equipped with Leica iCON roller solution are used for compaction of the ground and used extensively during winter to avoid that the ground freezes. The work progress is automatically logged with GNSS coordinates and transferred wirelessly viaConX.

Back in the office, Jonas Kleivbo works as a project engineer and explains how he receives as-built log point data from the soil compactor on the job site:

“I use the report module in Leica ConX to generate the compaction reports that are used as as-built quality documentation sent to the building authority, Nye Veier.”

“Norway is an example of a country that has extensively implemented machine control in the heavy construction industry. Hæhre started using machine control solutions in 2001 on one machine - today the firm owns more than 300 machines equipped with machine control solutions from Leica Geosystems,”explained Pål-Eirik Senland, solution manager for the product marketing management team.
