Remediation of a logistics centre

Retrofit for legendary high bay warehouse

In 1989 one of the most modern logistics centres at the time was erected in Berlin Tegel. The high bay warehouse with a height of some 40 metres, a total of 16 stacker cranes and approx. 70,040 pallet storage spaces served the firm of Herlitz as its production buffer store.

Today, i.e. more than 20 years after it was first commissioned, the logistics real estate has become a part of „Dock 100“ - a commercial and logistics park on Borsig Port.  The operating company is letting the „logistics dock“ to a number of clients.

Within the scope of comprehensive retrofit measures, Unitechnik has been entrusted with the order to replace important elements of the control and warehouse management system with new modern systems. To be put to use are S7 controls and Unitechnik‘s UniWare material flow and warehouse management system. One important requirement to be satisfied by the new warehouse management system is that the warehouse can be used flexibly by a number of clients.

Since the logistics centre is operational and must remain so all the time, the conversion measures have to  be accomplished while the warehouse is „in operation“. For this reason precise planning and thorough testing represent essential parameters for the success of this „surgical“ operation.
