Highrise building shell in weekly cycle

14.03.2014 | News
With the 81-m high Park-Tower, a new architectural landmark built in Zug next to the train station is to be completed in 2014. Doka delivers customized climbing formwork with protection screen for construction without scaffolds.
The project conceived by the Axess Architekten AG, Zug, and Cometti Truffer Architekten AG, Lucerne, reflects the principles of sustainable building in city centres. On a total of 25 levels, the new Park-Tower will provide space for residences as well as businesses.
The building contractor, Implenia AG, planned construction of the building shell for the 25 upper floors in a weekly cycle. "With extremely thorough preparation, efficient equipment selection and proper use of construction crews, some of the stories even required only four workdays", explains Franz Stadelmann, Implenia Project Manager.



Innovative formwork solutions for core and slabs

For efficient realisation of building core and floor slabs for the 25 stories of the Park-Tower, Implenia AG relied on formwork with a proven track record for success. For this project, Doka Schweiz AG delivered climbing formwork and a protection screen encasing the three uppermost floor slab levels at a time. The protection screen with its unfolded length of 100 m consists of 22 individual elements. A 1.50-m wide overhang at the upper end is used as space for working. A Doka table lifting system is integrated into the circumferential protection screen. It covers four stories and climbs automatically as an exterior lift. Floor by floor, the entire facility is lifted hydraulically by the height of one storey.

Doka's framed formwork Framax Xlife is used to form the core. It climbs by way of 14 automatic climbing formwork SKE50 plus with a travelling unit. A two metre high handrail post system ensures high safety standards. In addition, the system provides the option of lifting large platform gangs as well as comfortable adjustments to the formwork. In addition to Dokamatic standard tables, project-related tables are used as well for the slabs. DoKart table shifting devices powered electrically are used to reposition the tableforms.

Project Manager Franz Stadelmann has a very positive overall impression of the work completed on the Park-Tower with the help of the core formwork and protection screen. Thanks to the windshield, it was possible to continue working and pouring even during the coldest months. Modern equipment such as tableforms for slabs, DoKart shifting device and formwork lift simplified work and saved time. A Doka-Team provided efficient support for both, assembly and training courses for the crew. As a result, forming and pouring stages progressed smoothly from the very beginning. At the same time, the safety standard was always high. There were noticeable material savings that could be quantified and far fewer limitations in the lower construction site environment.

Construction began in February 2012. Transfer of the completed residences is scheduled for mid-2014.
