E4 Stockholm Bypass - Operator Certification
E4 Stockholm Bypass – Förbifart Stockholm – is a new route for the European highway (E4) past the Swedish capital. The purpose of the project is to build a 21 km long route, where 18 km will be through tunnel. When finished, the road will carry 140 000 vehicles per day. The project is already ongoing and is estimated to continue until 2026. The budget for the project is 3.1 bn Euro.
In order to secure high quality and safe tunnels Trafikverket (The Swedish Transport Administration) demands that operators working with sprayed concrete, injection and bolting should be project certified. Edvirt is accredited by Trafikverket to deliver training and certification courses for sprayed concrete and injection.
