Header Projekt IE Life Science Hygienesichere Produktion von Babynahrung

Production expansion of a new wet line for the production of high-quality baby food.

Nestlé S.A., Berne, is the largest food product and industrial company in Switzerland with a focus on nutrition and health science. Due to the constantly increasing demand for baby food and the planned expansion of the company’s range with speciality products, a second wet line was to be set up at the production site in Konolfingen. The so-called new wet line (NWL) also included new halls for milk collection and spaces for the development of sustainable production processes for business partners around the world. IE Life Science was tasked with the whole construction, logistics and hygiene planning as the design and management contractor.

The challenge.

The demanding framework conditions in connection with an ambitious schedule posed a few challenges for the IE Life Science experts. Because, in addition to the legal requirements for industrial food production, Nestlé must adhere to its own, very strict, standards and the applicable standards for pharmaceutical products. In addition, further high requirements are triggered with regard to hygiene and the zoning concept. Based on the tight spatial situation, the planning of building services and ventilation also turned out to be particularly complex.

The success factors.

Based on an IE master plan drafted together, an overarching hygiene concept was developed, broken down between the respective areas and the corresponding structural measures were defined. In order to ensure as much flexibility as possible between the individual production stages, the new wet line (NWL) was set up directly in the existing industrial building. So as not to disturb active operations while doing so, the individual construction stages were each completed in a self-contained manner. Only then was this opened to the old building and the continuing installation of the production facility. The incorporation of special concrete roof elements in the flat roof was particularly innovative. These could be opened individually for the installation of staggered supplied production facilities.
