66 Category 1: Buildings 1 De Rotterdam - Rotterdam, The Netherlands SE Owner De Rotterdam CV Architect Office of Metropolitan Architecture (OMA) General Contractor Strabag Züblin Engineering Office Royal HaskoningDHV Construction Period 2009 - 2013 The high rise project De Rotterdam is being described as a vertical city. With three 150 m high towers, including residential, commercial, hotel and parking facilities, the building is a giant that has no equal in the Netherlands. Special design features include the large cantilevers at the midpoint of the building height and the settlements due to the clay layer present below the sandlayer which is the base of the pile foundation. SCIA Engineer was used to investigate the soil-structure interaction and investigate deformations of soil and structures from the earlier stages of construction until 30 years after completion. Measures against excessive settlements, like using hydraulic jacks to shorten or lengthen columns, have been analyzed using SCIA Engineer. The results from SCIA Engineer were key to discussions on the topic of settlements with all the stakeholders, including the client, subcontractors for finishing, the main contractor and the municipality. Actual measurements so far show that the predictions were accurate. SCIA Engineers ability to handle large amounts of data enabled us to model with a minimum amount of simplifications, and the wide range of options to, for example, include the effects of hydraulic jacks in the buildings were a key success factor in this project.
