BIM technologies are driving collaboration on the construction of the £300m Stockholm bypass, according to formwork contractor Doka, which is working on six sections of the mega-project.
The bypass is 21km long, 18km of which are underground and when complete it will be one of the three longest road tunnels in the world. Doka is working for the main contractor, Spanish infrastructure giant Comsa.
Doka’s recent focus has been on two tunnels to the south west of the city centre, both open cut and measuring 160m and 130m in length. As well as the two tunnels, including entrances and exits, the work includes two 20m-long routes in rocky terrain as well as a pair of trough structures, the expansion of existing infrastructure and numerous stabilisation measures along the route.
