Structural design

At its Pratteln site, Planzer Transport AG is extending the logistics center it opened in 2006 to include an impressive additional structure. The new building has 24,600m2 of storage space, a transshipment area of 2,000m2, 50 truck loading bays split over two levels, plus 1,000m2 of office space. On the ground floor, two additional covered tracks are being added to the existing rail connection. On top of the first-floor ceiling is a high-bay storage area that extends along approximately two-thirds of the building's length. It occupies 6,300m2, is 22m high and has capacity for 27,000 europallets.

In close collaboration with the developer, and following in-depth discussions with the rack planner, a design was drawn up that guarantees the client a permissible deformation of the first-floor ceiling of 1/1000. For a reinforced concrete ceiling with an 8-meter span, this represents a structural solution verging on the bounds of feasibility. Work had to be carried out alongside ongoing operations at the Pratteln I logistics building. The second delivery level on the first floor of the new building presented a major challenge. Two temporary ramps were constructed to compensate for the one-story height difference and temporarily divert incoming and outgoing trucks around the building site.
