Rotterdam, self-lifting building shed erecting 120 m high EMC tower

General information

In order to build the new 120 meter high Erasmus Medical Center safe and in closed conditions, CT deBoer designed a self-lifting building shed. This shed was equiped with two 40-tons overhead cranes and a storage and lunch area. Hydraulic jacks to lift the entire shed another floor are attached at 4 positions. The planning was done in such a way, that every 5th working day the shed would be lifted one hole floor up. This would go in the following way:
The schedule shows that:
– at STEP 1 the building shed is resting on the red truss,
– at STEP 2 the floor is erected (in pink),
– at STEP 3 a second truss is placed in the just-erected-floor (green),
– The building shed is then lifted one floor height in strokes of 25 cm.
– STEP 1 is repeated, but now the building shed is resting on the green truss.
– at STEP 2 another floor is erected (in light green).
