This achievement requires the player to deliver a succesful job to all quarries in Scandinavia. There are 7 quarries in total, namely:
- Kristiansand, Norway
- Oslo, Norway
- Stavanger, Norway
- Jönköping, Sweden
- Kalmar, Sweden
- Linköping, Sweden
- Växjö, Sweden
So when looking at the available jobs, you're looking to get a job with a destination going to one of these places. The company it has to go to is either MS Stein or Nordic Stenbrott. You can filter the jobs on recipient (or along the likes of that) to make the list alphabetical on the name of the companies.
These loads are often pretty heavy, like heavy machinery so if you use your own truck, make sure you got a truck which can actually pull those heavy loads. Or just do a quick job (which always gives a truck that can pull the weight).
If you delivered a job (doesn't matter which load) to either MS Stein or Nordic Stenbrott to each of the seven cities, the achievement should unlock.
