For the first time in Zurich, rectangular precast concrete elements were used for constructing man size sewers in open trenches by realising the projects “Riedtlistrasse” and “Moränenstrasse”. Thanks to an innovative mounting system developed by DSE systems, the precise mounting of one element took no longer than 15 minutes on a previously prepared lean concrete surface. Thus, the use of precast elements allowed a substantial reduction of construction time in comparison to the traditionally built sewers with cast in-place concrete. The concept of the construction process was developed at an early project state in creative and innovative teams consisting of engineers, precast contractor, and owner/ client. Working together at such an early stage of the project was crucial for finding innovative solutions that fit all requirements. These innovative solutions enabled the setting of new milestones in Zurich sewer construction.
