Single Source Formwork Solutions for Multi-Tower Project - continued

Coordinated climbing formwork and shoring solution

The construction team could realize the stable structure base efficiently, safely and in a correspondingly short time right from the very beginning.

Coordinated climbing formwork and shoring solution

For working at heights, Peri engineers planned the optimal combination of different climbing systems.

With the help of RCS Climbing Formwork units, CB Working Platforms and BR Shaft Platforms, the vertical reinforced concrete components and circular inclined supports were efficiently and safely constructed.

For the most part, the VARIO GT 24 Girder Wall Formwork was combined with the respective climbing system.

Following the fast working speed of the climbing technology, PERI UP was assembled as a birdcage scaffold with a basic grid of 1.50 m x 1.50 m. The scaffolding provided safe working and access areas at all levels.

In addition, corresponding intermediate supports could be realized with the construction for the required horizontal bracing of the inclined reinforced concrete columns. The solution for this temporary stabilization of up to 30 m high inclined columns was developed by Peri engineers in close cooperation with the structural engineers from ARUP; for this, ST 100 Stacking Towers were used as well as specially developed connection components.

Flexible adjustment to suit different geometries and loadsFlexible adjustment to suit different geometries and loads

The dimensioning of the PERI UP birdcage scaffold was especially coordinated to accommodate the subsequent load-bearing function in order to concrete the up to 1.80 m thick intermediate slabs at heights of over 40 m.

Due to the 25 cm system grid, the scaffolding could be flexibly adapted to suit the building’s geometry. As a result, different set-up levels, circular columns at inclined spatial angles as well as increased load concentrations could be taken into consideration – and this with optimized material quantities.

In the birdcage scaffold, integrated PERI UP aluminium flights of stairs also provided safe access to all areas.


The challenge is to find alternative power supply for lifting gear.Are You Up To The Challenge?

Here is your opportunity to show your skills at innovating new solutions for applications in the construction and related industries.

The challenge is to find alternative power supply for lifting gear.

The first Open Innovation project was organized at bauma 2016. Now, in mid November 2016, a new challenge is going online, this time with the aim of finding an alternative power supply for lifting gear.

The solutions submitted by experts are handled anonymously and passed on directly to the issuer of the challenge. Prior registration is required, at: openinnovation.bauma.de.

Challenge brief

In the current challenge that has been commissioned through bauma Open Innovation, the brief is very wide-ranging:

The company is looking for an alternative power supply that must be reliable, easy to set up and dismantle, and may not cost more than the technologies used so far.

A particularly important aspect is that the solution must fulfill the requirements of the Machinery Directive and the EMC Directive. Data transfer must be secure and reliable.

The idea of Open Innovation

The Open Innovation project by bauma is based on the idea of taking the innovation issues faced by companies and translating them into “Challenges” to which the global and interdisciplinary community of experts then proposes solutions.

The process is particularly well suited to technological challenges that a company cannot resolve using only its own resources.

Especially as regards the highly complex innovation challenges faced in the construction machinery sector, this Open Innovation project is a good way for companies to tap into a very broad base of expert knowledge.

Another advantage is the fast turnaround time, which can reduce development time.
