RENTAL SOLUTION IN STOCKHOLM
Working on two short-term subway tunnel and station projects in Stockholm, Sweden, the Italian construction company Itinera had the challenge of acquiring expensive mining equipment or find another solution. It did so through a rental deal with Sandvik that includes equipment, parts and a full-time service agreement, says Mikael Vallgren
Itinera’s presence in Sweden has grown significantly with the Italian construction company securing two major subway projects simultaneously in in the capital, Stockholm. One of the projects is the Hammarby Kanal subway station lot with a 1.2km-long service tunnel and also a track tunnel of the same length. In planning, the challenge was either to acquire
expensive equipment for tunnelling or another solution – in this case opting for an equipment rental and services package. Leveraging Sandvik’s expertise, Itinera has been able to overcome the capital constraints associated with purchasing equipment outright. The partnership for Hammarby Kanal shows
collaboration can deliver significant results in challenging construction projects, with Itinera using Sandvik’s reliable machinery, on-site technicians, and comprehensive support to support smooth operations and to enable downtime to be minimised.
42 | September 2023 Several factors led Itinera to collaborate with
Sandvik, including prior experiences together and rapid deployability of the equipment on the tunnel project in Stockholm – crucial for meeting project timelines. Frida Hesselgren, Project Manager at Itinera, says:
“Many of us working on the project have previously collaborated with Sandvik as a supplier with good results, making it an easy decision.” Itinera, in previous projects, had primarily used tunnel
boring machines (TBMs) for excavation, but the Hammarby Kanal project presented challenges, such as how to create the particular tunnel alignments and do so in Stockholm’s exceptionally hard granite. As a result of these specific requirements – local geological plus the length and incline of the tunnels – the needs of the project called for the drill and blast method to be employed. This type of project is also challenging due to the urban location, working in and under a major city. The
