BIM successfully piloted for tunnel infrastructure works

Extension & upgrades on Karlsruhe-Basel rail line supported with Document & Communication Management

Rastatt Tunnel

Project

Rastatt Tunnel was part of section 1.2 of the expansion and construction works for the Karlsruhe–Base rail line. Rastatt Tunnel was the first German Railway (DB Netze AG) project to use government-funded BIM.

The tunnel was the largest of four nationwide funded BIM pilot projects, where the benefits of BIM were tested. Work consisted of mining and excavation of the 4.2m tunnel and construction of 2 single tracks. The project lasted from 2014 to 2022.

Challenge

As the first of four BIM pilot projects, the BIM technology used was a fresh concept for the project participants. Therefore, DB Netze needed to have buy-in from all teams to prove the benefits of BIM.

Solution

The Document & Communication Management and Virtual Design & Collaboration solutions within Thinkproject are tailor-made for Building Information Modeling.

Providing a three-dimensional view, Thinkproject simulates planning, building processes and operations for all phases of the project. Participants are afforded an early and realistic planning overview which shows geometric information, the building schedule and costs. This single source of truth allows teams to identify potential issues and take early countermeasures to reduce the risks of spiraling costs or delays.

Result

The complete overview, updated in real-time and with a full audit trail was a huge benefit for collaboration and communication throughout the project. The BIM pilot was a positive experience for DB Netze, who moved forwards with BIM supported by Thinkproject on numerous infrastructure projects.
