Dating back to 1997, WTM Engineers has been involved in consulting the construction of several warehouses and office buildings on the operating site of Schwarze & Consorten Lagerhaus GmbH in the port area of Hamburg. Now a new green coffee treatment plant for cleaning, interim storage, blending, and packing of raw coffee beans has been added.

The six-storey machinery and silo building was designed as a steel structure. The construction involved deep foundations with drilled displacement piles; it also includes a partial basement designed as a waterproof concrete structures.

In addition to the concrete road surfaces for the truck and reach stacker traffic, the outdoor area includes surfaces made of concrete block paving and a vehicle weighbridge. As a preparatory measure, fire water pipes had to be laid in addition to the explosive ordnance probe and pipeline construction work.
