High-rise warehouse CB

High-rise buildings with structural challenges

The number of orders is increasing, while the volume of orders is decreasing. A fully mechanised bin warehouse is a good solution for this, thought CB (formerly Centraal Broekhuis). They asked Denc and Pelecon to help think about the construction of the new high bay warehouse. We made all the main calculations, plan model and construction drawings.

The new high-rise warehouse measuring 30 x 100 metres and a height of 34 metres has been built against the existing premises. The extension is divided into a work area of 30 x 17 metres with lifts, conveyors, stairs, a passenger/goods lift, an office area, a pantry area and sanitary facilities. The extension consists of a steel structure, sandwich panels and five storey floors (hollow core slabs) with compression layer in the work area.

The role of Pelecon
In the high-rise warehouse, the design of the structure was independent of the racking. This made the design relatively simple with exceptions for the height of the high-rise warehouse. Project structural engineer Bastiaan Hoefnagel points out that the height of 34 metres meant the columns had to be heavier and constructed in sections. Wind catch also adds to the problem at that height. By having the existing high-rise structure stabilised to the new building, many kilos could be saved and a piece of sustainability was ensured.

Challenge
For the working area - the area where the containers with the orders come in and are processed - we calculated the entire foundation and steel structure of the five floors. Here, the existing buildings made it a challenge to get the heavy column loads onto the foundation piles, which was achieved by applying heavy floor beams.

We look back on a challenging but successful project!
