Project Information:
The project concerns the construction of the new, 2.36km long, four-track rail corridor, 1.49km of which is below ground (Cover&Cut). The project starts from the exit of Athens Railway Station towards Theesaloniki and ends at Tris Gefyres in Sepolia area of Athens, where it connects with the, recently completed and open to traffic, new four-track rail corridor.
The east half of the four-track corridor is intended to serve suburban routes, whereas the west half will be used mainly for intercity itineraries. The project is quite demanding since it is located in the heart of Athens Metropolitan area and moreover it crosses Line 2 of Athens Metro.
Client: ERGA OSE (No. of. Contr..: 726/14)
Date: 2014-2016
Location: Sepolia, Athens
Estimated Cost of Construction: 116.000.000 €
Scope of Work:
As per the requirements of the contract, our services, which included the full structural and geotechnical design of the underground structure (Cover & Cut) and the accompanying electromechanical facilities are briefly listed below:
- Structural & geotechnical design of cover&cut and retaining walls Our services for the project include the geotechnical evaluation and the foundation design as well as the detailed design for both the Cover&Cut and the temporary and permanent retaining structures.
Within the framework of the contract, the geotechnical evaluation and the foundation design of the Cover&Cut and the accompanying E/M Buildings were carried out.The preliminary and final structural design of the underground engineering using the Cover&Cut method as well as the preliminary and final design of the temporary and permanent support techniques were also carried out.
- Study of the interaction of the underground engineering with the existing neighbouring buildings and the Metro tunnel at their intersection..
- Static Geotechnical and geotechnical study for the E/M buildings of the project (Preliminary Design/Optical/Implementation Study).
