Accident-free construction with PERI UP Easy

On the basis of the PERI UP Easy scaffold system, which was assembled in line with the actual construction progress, work operations could be carried out quickly and safely. In spite of the challenging building geometry and cramped jobsite conditions, completion took place within the planned budget and time-frame, and without any work-related accidents. The "Ypsilon", with its 10-storey, 35 m high tower structure and adjacent 7-storey lateral tract, is Ulm's new, striking western gateway to the city centre. Rounded building corners on all sides with a corresponding aluminum-glass facade provide the building complex with a modern appearance. Retail outlets, offices, apartments and micro-apartments have been accommodated on 6,300 m² of usable space – in a central, convenient location directly next to the "Ehinger Tor" public transport hub. The trapezoidal-shaped tower floor plan in connection with the lateral tract result in a building geometry that, viewed from above, resembles a horizontally-positioned "Y". After 22 months of construction, the topping-out ceremony took place in July 2018.

Challenging requirements

The demands placed on the contracting company Matthäus Schmid GmbH & Co. KG in its role as general contractor were high. In addition to the challenging geometry of the structure with sloping walls and rounded corners with different radii, the building complex including the two-storey underground car park was supported on 25 m long bored piles. Moreover, the inner-city construction work had to contend with a tight schedule regarding construction site logistics due to the Ulm tramway expansion project that was taking place at the same time. Likewise, directly adjacent local transport services were not allowed to be negatively affected and tough safety requirements had to be met in order to protect passers-by.

A comprehensive scaffold concept on the basis of the PERI UP Easy Facade scaffolding system was developed together with Schäfer Gerüstbau GmbH and PERI. This provided end-to-end work and safety scaffolding – assembled in line with construction progress – for all building shell and facade work. A pedestrian tunnel was integrated into the scaffolding solution that ensured convenient accessibility along with a high level of safety for passers-by during the entire construction phase. From the shell of the structure through to completion, the basic scaffold assembly could be maintained and did not have to undergo any time-consuming and costly modification work. All required adjustments were carried out by means of easy-to-install console bracket extensions.
