Olympic Tower Munich

Project Description

The Olympic Tower was constructed in 1968 for the 1972 Olympic games in Munich. The tower is all together 290 m. tall; the lower prestressed concrete shaft has a height of 175 m.

Task

The Olympic Park Munich Gmbh commissioned us to determine the current condition of the tower shaft, to gather information  on possible future damage and based on the data gathered in the investigation create a service life measurement for the proposed remaining service life of 100 years.

Procedure

Aside from visually acessing the damage to determine the condition, on large areas concrete cover measurements were conducted and the depth of carbonation was determined.

Taking the actual concrete properties into account, the expected carbonation progress was fully probabilistically calculated with respect to the corresponding exposure conditions and compared with the existing concrete cover. This way it was demonstrated that for the designated remaining service life of the Olympic Tower (approx. 100 years) a sufficient reliability toward carbonation induced reinforcement corrosion was guaranteed and within the remaining service life no comprehensive repair work on the concrete surface should be expected.
