Transport infrastructure / rail
Project
North Sea – Baltic Railway Corridor, Rail Baltica Railway Line, New construction of railway section Parnu – Estonian/Latvian border in Estonia
Location: Estonia
Client: RB Rail AS, Rail Baltic Estonia OU
Date: 2020 –
Construction costs: approx. € 900 million
Technical Details
The project involves the construction of the new Line connecting Pärnu in Estonia to the Estonian/Latvian border. The railway section has a total length of 93,5 km, two rail tracks and the maximum design Speed is 249 km/h. The section has 10 Railway bridges, 23 Overpasses, 7 underpasses, 3 stations platforms, 12 Ecoducts, 110 culverts and retaining walls. The project adheres to the EU interoperability requirements and designs are according to the relevant Estonian and European regulations.
The project is to be constructed in quite demanding geotechnical and geological conditions. Especially for the part of the route on the accumulative lowland of Pärnu, soils with poor geotechnical properties and with a thickness in the order of 100 m or greater are met. Groundwater is close to the ground surface in most of the route.
OBERMEYER’s assignment embraces the provision of engineering services in both the design and the construction phase, with design supervision services. This project is one of the first infrastructure projects worldwide to be executed in a full BIM environment
The Design process comprises five stages:
- Site Investigations
- Value Engineering
- Master Design
- Detailed Design
- Design Supervision Services
