Finnish contractor Lemcon Oy has opted for the most advanced drilling technology available for a major railway project in western Sweden.
Lemcon, part of the Lemminkäinen Corporation – Finland’s oldest construction company with more than 7,000 employees – has chosen to use two Rocket Boomer XL4C30 drill rigs from Atlas Copco, furnished with COP 3038, the world’s fastest rock drill.
In addition, Atlas Copco will supply all of Lemcon’s needs for rock drilling tools and rig maintenance during the project, expected to be one-and-a-half years from start-up in January 2006.
The rigs will be put to work on the Trollhättan to Gothenburg twin-track railway. At about the half-way mark, near the historical site of Lödöse, Lemcon will prepare the groundwork for a new 7.5 km section of twin-track as well as construct a 3 km main tunnel – a total of 5.5 km with service and rescue tunnels.
The Swedish Railway Authority has had previous experience of working with Lemcon on a tunnelling project that subsequently won an award. For the new assignment, performance was Lemcon’s top priority coupled with a desire to acquire the absolute latest tunnelling technology.
According Timo Kohtamäki, Vice President of Lemcon, the combination of the four-boom rigs with their advanced computer control systems, the super-fast COP 3038 rock drills, the service package and, not least, the flexibility of the financing arrangements provided by Atlas Copco Customer Finance all contributed to the decision.
