PHS CENTRAAL STATION, AMSTERDAM

Amsterdam Central Station is one of the busiest stations in the Netherlands, with a growing number of visitors each day. To cope with this growing passenger demand, various works are planned at and around the station over the next few years as part of the High-Frequency Rail Transport Programme commissioned by the Ministry of Infrastructure and Water Management.
The PHS Amsterdam Central Station (PACS) project is part of the overarching High-Frequency Rail Transport Programme (PHS). The project involves track optimisations, replacement of the steel bridges of the Ooster access, realisation of a flyover near the Dijksgracht and optimisations within the station building.
Inside the monumental station building, more space will be created for passengers by widening and lengthening the platforms. The access from the west passenger tunnel to the main building will also be renovated and the narrow east tunnel will be converted into a wider tunnel. There will also be a new bicycle shed under the tracks on the east side of the station building and the railway bridges on the east side will be replaced.
The work on the east side of the station building will be carried out from the IJ side, with the bridges and associated track box being replaced one by one. The bicycle parking facility under the railway trough will be built simultaneously with the execution of associated railway trough.

GEO2 Engineering B.V., commissioned by Strukton Infra Specials B.V., is preparing the geotechnical design (supplementary DO) of various structures for the railway troughs and bicycle parking under the tracks in the eastern part of the station.
The geotechnical design considers:

Retaining structures for the purpose of adjacent tracks remaining in service;
Temporary piles for temporary structures, such as platforms for the tracks remaining in service and overhead crane;
The bearing capacity and sagging of the new cycle shed under the tracks; this will include the influence of the complex phased construction of the tracks/bicycle shed;
Influence of structures on various adjacent structures, and influence of adjacent/existing structures on the new structure.
