DYWIDAG Bar Post-Tensioning Tendons preserve Cultural Heritage in Lisbon:
The historic Hotel Cais de Santarém
In the historical district of Alfama in Lisbon, a new five-star hotel belonging to the Hotusa Hotels Group is
being built. The new 91 room Eurostars Hotel is being developed near the future cruise terminal on a total
area of approximately 8,400m².
In this special construction project, the
former palace of the Marquis of Fronteira
and the Count of Linhares is being restored.
The palace was severely damaged by an
earthquake in 1755 and was temporarily used
as a storage facility for iron in the 19 th century.
Due to the fact that important archeological
findings from the Roman times and other
periods have been discovered on the jobsite,
the hotel will also be a museum.

The General Contractor, Constructora
SANJOSE, was awarded the contract for
demolition work, digging the excavations
and building the necessary containment
structures. Due to the palace’s advanced state
of decomposition, the General Contractor had
to be very careful and precise. Combining the
technical demands of a five-star hotel with the
preservation of an important cultural heritage
site was another major challenge.
First, all elements that were either
contemporary or of low archeological
value were demolished. Afterwards, a
foundation consisting of micropiles was
built for which bore holes with a total
length of 9.5km were necessary.
Subsequently, reinforced concrete
blocks were positioned on the base
level of the existing walls on top of the
steel piles.
