The former locomotive production factory known as „Loki“ in the middle of Winterthur is being redeveloped as a residential and commercial complex. The new buildings will house 211 appartments as well as various trade and retail facilities. Thanks to its central inner city location, the area is very easily accessible. Sustainable development is an important issue, following the strict Swiss “Minergie®” energy saving standard. Three new buildings are arranged around a spacious inner park. The varying building layouts required a meticulous approach to formwork and workflow planning.
The architects required a special board-style concrete surface in the staircase. This was achieved effectively and quickly by mounting a one-off plywood sheet onto the Mammut 350 wall formwork panels. The photo belows shows the dramatic effect achieved this way.
The side opted for all-round safety provision during the entire building process. This included equipping the wall formwork Mammut 350 with the modular safety system SecuritBasic. It offers an all-around fall protection, safe and comfortable working platforms and access ladders. The push-pull props are attached to the back of the walkway bracket. They do not project from the working platform or planking, thus avoiding tripping obstacles.
MevaDec slab formwork mastered the changing building layouts with a minimum of filler areas since it is not restricted to any fixed grid, making slab works easy and fast.
Poject manager Sander Thijssen of BAM Swiss AG says: “Particularly´the solution with plywood facing mounted onto the Mammut 350 to achieve the board-style concrete finish worked very well.“

High, Fast, Safe: A state-of-the-art biopharmaceutical production plant is being built for the US biotechnology company Biogen, located on the grounds of a former paper factory in Luter bach near Solothurn, Switzerland.
One of the latest thrills: Float like a bird at a skydiving center, where an artificial airstream will keep you up in the air.
The solution: table forms, 5.40 m long to exactly fit into the openings between the columns. Short filler pieces with rounded edges provided a perfect match to the column layout.
