| Crane-independent building redevelopment  During the refurbishment of an apartment building on Bollenhofstrasse in Dietikon, Switzerland, the constraints were clearly defined: work within the existing structure with limited space, and do not continue to use a crane once the slab has been concreted. Therefore, for the formwork operations on a sloping reinforced concrete slab and a lift shaft, the required solution needed to be adaptable, easy to work with and capable of operating without the need for a crane. With the DUO Universal Formwork system, the contractor, Wanner & Lott AG, opted for a system that is specifically suited to these requirements. Working without a crane – even after the concreting phase A major challenge posed by the project was that it was no longer possible to use a crane once the slab had been concreted. Therefore, the formwork solution used had to be easy to work with even without lifting equipment. DUO Universal Formwork met this requirement thanks to its low weight: all components in the system weigh less than 25 kg and can therefore be carried and fitted by hand. This meant that the formwork operations could continue efficiently even without access to a crane. One system for multiple applications In this project, DUO was used for both the lift shaft and the sloping reinforced concrete slab. The versatility of the system was particularly evident during the construction of the sloping reinforced concrete slab. Thanks to the adaptable modular design, the formwork could be adjusted to the required geometry. "You can build to any specifications," says foreman Claudio Grassi, describing the system's advantage. DUO's high level of adaptability reduced the need for additional formwork solutions and simplified the performance of various formwork tasks on site. Lower material requirements and cost-effective implementation As well as being easy to use, DUO impressed with its efficiency on site. Deploying the system made it possible to reduce material requirements compared with a conventional solution. "Without DUO, we would have needed a lot more materials. "That's how we managed to make quicker progress," says Claudio Grassi, summing up his experience. Furthermore, it was possible to use existing materials for the most part, which had a direct impact on the project's cost-effectiveness. A versatile solution for building redevelopment The project in Dietikon demonstrates the benefits of DUO in building redevelopment projects. The lightweight system components enabled work to be carried out without the need for a crane and made handling straightforward on the construction site. As the DUO system could be used for both the sloping reinforced concrete slab and the lift shaft, a single system was sufficient to carry out a variety of formwork tasks. This simplified the planning process and made it easier to carry out the work on site. write your comments about the article :: © 2026 Construction News :: home page |
