60 kN/m² for walls and up to 75 kN/m² forcolumns minimises errors and speeds up theconcreting process.

Assembly is carried out quickly and intuitively byjust two people – without the need for a crane.
This makes HANDSET Alpha particularly efficient.

HANDSET Alpha is a robust entry-level formwork system for walls, foundations
and columns. The system consists of a low number of sophisticated components
and multifunctional panels that make handling intuitive. This streamlined, integrated portfolio keeps the need for on-site training to a minimum and saves valuable
time and costs. Only two people are needed to assemble the system. A crane isVideo

not required. The high quality steel and powder-coated panels make HANDSET­Alpha particularly durable and reduce maintenance costs.

The low number of reusable system components
reduces the amount of material loss on the construction site as well as the amount of timber required.

The multi-panels with integrated tie holes at
5 cm intervals provide a high degree of flexibility
and reduce the volume of material held on site.

The PERI UP Trench Bridge is a quick and easy solution for crossing over construction pits, trenches and channel trenches
in a safe manner. The assembly process relies on standard components of the PERI UP Scaffolding Kit and can be carried out quickly thanks to system-integrated features such as self-locking decks and tool-free installation of the diagonalbraces. In addition, the trench bridge has proven to be robust in the face of atmospheric influences.

PERI UP Reinforcement Scaffolds
Ensuring stability when working on formwork

The PERI UP Reinforcement Scaffold with its two base widths of 150 cm and 250 cm was designed for activities
related to reinforcement, formwork and concreting. The standard configuration of the stable scaffold can be erectedusing up to 3 bays in the longitudinal direction and can be assembled quickly thanks to the self-securing ledger connection and the lift locks integrated in the decks. It does not need any ballasting or ties as long as it is supported in
front of a wall or formwork. On account of its tension-proof connections, even large units of the PERI UP Reinforcement Scaffold can be moved in their entirety by crane. The PERI UP Reinforcement Scaffold also ensures a high levelof safety by virtue of its continuous, uniform and gap-free deck surfaces. What’s more, the planning process is simplified by the ability to quickly determine the material requirements with the help of pre-assembled units.

On account of its tension-proof connections,even large units of the
PERI UP Reinforcement
Scaffold can be moved intheir entirety by crane.

System width: 75 cm and 100 cm
Scaffold bay lengths: 150 cm, 200 cm, 300 cm
Maximum standing height 6.60 m (with base width 150 cm) or 10.80 m (base width 250 cm)
Working scaffold load class 1 - 3 in accordance with EN 12811-1, can be loaded with 0.75 kN/m² to
2.00 kN/m²
Thanks to pre-assembled units, the material
requirement can be determined quickly, thereby
facilitating the planning process.

The PERI UP Reinforcement Scaffold can beused in front of formwork and walls without any

RCS MAX Rail Climbing System
Efficient and safe climbing formwork withsynchronous climbing platforms

The RCS MAX Rail Climbing System is the further development of the proven RCS Rail Climbing System and stands
out, among other things, on account of the fact that all of the platforms can climb simultaneously, thus improving thelevel of safety and productivity on the construction site. The two new modules, the RCS MAX Hydraulic Unit and the
RCS MAX Drive Rails, are fully compatible with the RCS Rail Climbing System and ensure an accelerated construction process. The synchronous climbing of all platforms as well as the load transfer via the lower climbing section shortens the
climbing cycles and, consequently, the construction time of projects. The intuitive plug-and-play configuration and lightweightcomponents make the system easy to assemble and operate. The hoses and cylinders are placed in predefined positions once
– no repositioning is necessary, ­meaning that sources of error are reduced. In addition, clever features such as the dead man’sswitch and an emergency stop switch on each platform ensure an innovative safety concept.
The synchronous climbing of all platforms­increases safety on the construction site. Openbuilding edges are thus a thing of the past. Thiseliminates tripping hazards and the risk of fallingparts.

the new RCS MAX components also ensures optimised system per­formance. What makes the RCS stand out above all else is its variableoptions of assembly, which means that the platforms can be flexibly
adapted to different floor heights. The climbing shoes can be attached
to walls as well as slab edges, making RCS suitable for any building
geometry. The climbing units are securely connected to the structure
at all times using climbing shoes, which enables safe and fast climbing,even in windy conditions. The system is used both as climbing formwork and as a climbing protection panel.

The system protects the inner areas against the effects of wind, whilestill allowing light to shine into the building. The lightweight screen
elements can be assembled quickly and without the need for a crane.
Alternatively, the LPS system can be delivered pre-assembled, saving
valuable time and space on the construction site. Having a permeable
structure, the lightweight mesh panels exert reduced loads to the building and therefore can be used with thinner slabs. LPS is used as avertically continuous climbing protection panel. Moreover, integrated
working platforms provide access to the slab stopend formwork.

As a working platform for building
construction
The VGK can also be used as a working platform for building
construction. To ensure that the work procedure is safe, theconsole brackets can be suspended in the structure as a
pre-assembled platform unit. The result is an enclosed working platform on which reinforcement scaffolds can be placed.
Formwork can be handled and other work carried out from asafe position, making the use of facade scaffolds superfluous.
VGK Console Bracket solutions are type-tested. They can also
be measured independently with the VGK Design Tool.
As the folding platform carries very high loads,
high facade scaffolds can also be installed on theplatforms. This is beneficial, for example, if theterrain is rough beneath the working area.

3D Construction Printing

Maximum dimensions of COBOD BOD2: 15 m wide, 10 m high, the length can be adjusted according
to the individual project requirements
Printing speed: 1 m/s maximum speed; 25 cm/s standard speed, which corresponds to a printing timeof around five minutes for 1 m2 cavity wall

Printing buildings in a time and cost-effective mannerwith the COBOD BOD2

Layer heights and widths: Realisation of layer heights between 1 cm and 3 cm as well as layer widths
between 3 cm and 10 cm
Printing materials: Any locally sourced 3D-printable mortar or concrete with a maximum grain sizeof 8 mm
Assembly and disassembly time: Depending on the configuration of the 3D construction printer,
for a printing area that is 12 m wide, 17 m long and 8 m high, for example, 8 hours are required forone machine
Safety technology: CE-certified and safe, IP67-certified cabling and galvanised steel tracks, camera
monitoring of the printing process and printing results

With 3D printers, concrete structures can be built quickly
and cost-effectively without the need for formwork. It takes
about five minutes to produce 1 m² of double-skin wall witha COBOD BOD2. Given the high level of automation, only
two people are required to assemble and then operate
the printer, which minimises personnel costs. In addition,
3D construction printing stands out due to its considerable
freedom of design, meaning that custom structures canbe realised without any issues.

Integrating other trade activities into the printing
process, such as insulation material or cableducts, further increases efficiency.

The innovative 3D printing technology requiresvery little effort and impresses with its clean
method of operation, which has a positive impact
on the employer’s reputation.

Germany’s first 3D-printed residential building
in Beckum with curved walls exemplifies theconsiderable design freedom offered by 3D construction printing.

The most stringent architecturalconcrete specifications
realised on schedule

In the shade of tall pine trees, a private residence in Viimsi, Estonia,
stands out on account of its contrasting architecture. The combinationof timber and high-quality architectural concrete blends seamlessly withthe landscape and reflects the owner’s passion for distinctive concrete
structures. Due to the high demands placed on the quality of the architectural concrete and the level of field service required, the customer
opted to collaborate with PERI.
A concrete frame with an architectural concrete finish links the L-shaped building to a separate sauna. The customer wanted to use a uniform tie pattern andarchitectural concrete of the highest quality to give the walls of the frame aradiant appearance, so PERI offered several different technical options using
a variety of panels and tie options. Ultimately, the customer decided to use
TRIO Panel Formwork with a combination of panels in different sizes, which
afforded the building a harmonious and engaging concrete finish with an orderly
tie pattern. In addition, with its small number of different components and thesingle-hand operable BFD Alignment Coupler as the only connecting part, TRIO
ensured that construction progressed quickly.

ProSiebenSat.1
Unterföhring

In Unterföhring, four state-of-the-art TV studios and office and conference rooms will be built
on a 26,000 m² site by 2024. There will be space for 1,700 employees across five floors, including
several garden and roof terraces for creative exchange. PERI supported the project with systemsolutions consisting of PERI UP and VARIOKIT.

Hitting the heights quickly
and safely with PERI UP
The variability of the PERI UP Scaffolding Kit simplified the assembly workat the New Campus immensely. On account of the end-to-end system
grid, PERI UP can be adapted very flexibly to various local circumstances.
It is also possible to ensure a smooth transition between the shoring
and facade scaffolds. Since the VARIOKIT Engineering Construction Kit
is based on the same basic grid, both systems can be combined almost
seamlessly into a comprehensive solution. In Unterföhring, too, the facadescaffold was supported with the aid of various VARIOKIT core components
wherever the substrate did not offer sufficient stability or traffic areas had

tive RCS MAX Rail Climbing System’s first outing on
Korean soil.

The main benefit of the system, however, became apparent
during the climbing operation itself. The decentralised hydraulic units ensure a significantly higher level of safety at every
stage of the climbing process. This is because the hydraulicunits allow all of the console brackets to be climbed simultaneously. This means that personnel are not exposed to hazardous open building edges. The RCS MAX system also stops automatically in the event of a collision or overload and
immediately alerts the user to any issues by way of a light signal or the attached display. The system’s features gave theconstruction site team full control at all times and helped toreduce any downtime. What’s more, since the RCS MAX system transfers the load via the climbing section below, the platforms can be readied for the next climbing section more
quickly.
Consequently, the decision to use the RCS MAX system led
to a considerably higher degree of work safety and, at thesame time, shortened the construction time of the residential
towers. In other words: not only greater safety, but also greater efficiency.

virtue of their elliptical design, with each of them providing living andrelaxation space across 31 storeys.
For the construction of the three residential towers, PERI delivered 38,100 m²
of scaffolding material weighing 850 t to the site in Slovakia. On accountof the high axial forces, the PERI Scaffolding System provided the optimal
solution for erection of the facade. In the lower section, which reaches aheight of 25 m, PERI UP Shoring was used as this guaranteed a high degreeof load-bearing capacity and versatility. The PERI UP Facade Scaffold waschosen for the upper section.
In addition, a combination of the RCS Rail Climbing System and VARIO formwork proved to be the optimal choice for concreting operations carried out atheight: in each case, a VARIO panel climbed upwards in 50-cm-increments
together with an RCS Platform. The system could be adapted quickly and easily
to the shape of the building because the individual VARIO panels could also
be specially adapted. This also made it possible to form the slab edges. The
foundation slab, exterior walls, ceiling slabs, stairs and lift shafts were formed
with TRIO. The MAXIMO Formwork System, which can be operated from one
side and features panel heights of 300 cm, was used for the interior walls.
The planning and execution phases of the residential building project were
extremely complex due to the elliptical shape and the height of the building.
Thus, two different teams were involved in the planning phase of the project:

The new 150 m tall residential tower CoolTower
has been built in the middle of Rotterdam’s lively city centre, between the Witte de Withstraat,
the Schiedamsedijk and the Vasteland. With its
striking crown as an eye-catcher, it blends into theRotterdam skyline – and offers space for an impressive entrance area and 283 high-quality flats on 50
floors. The attractive residential project was carriedout with an optimally coordinated combination of
PERI formwork and scaffolding materials.
Each of the flats has its own balcony, made possible by
the building’s fully load-bearing core. This was concretedusing the ACS R and ACS P Modular Self-Climbing Systems in combination with VARIO GT 24 Girder Wall Formwork. The self-climbing solution scored particularly highlywith its speedy processes for shuttering and striking, as
well as the integrated hydraulic system, which enabled arapid concreting cycle for the core walls of just six days.

Tour Mirabeau
Marseille
FranceSwift construction progress­despite high wind loads and limitedspace
One of the tallest office buildings in the city is being built directly on the
Marseille coast. The 85 m high building has 21 floors of state-of-the-art, energy-efficient office space with views of the sea and the neighbouring city. PERI
supported the three-year project by supplying a wide range of systems.

The immediate proximity to the Mediterranean Sea not only meant that space
was limited during the construction phase, but also led to special requirements
in terms of safety. The high wind forces, for example, proved challenging. By
using the LPS Climbing Protection Panel for enclosure purposes, however,
the workers were effectively protected from the high wind loads even at greatheights and the possibility of falling objects was ruled out.
The RCS C Rail Climbing System used for the construction of the facade also
ensured a high level of work safety, with the climbing unit being securely connected to the structure at all times via the rails.
The climbing system was combined with the MAXIMO Panel Formwork,
which resulted in a very high level of concrete quality. Furthermore, theself-climbing system with its retractable formwork not only minimised theContractor

formwork projects. The good cooperation with PERI
contributes to a great result on the construction site.”

One of the most important success factors in large-scale
projects of this scale is time. The efficiency of the formwork solution was therefore just as important as thefact that the delivered material enabled simultaneous
construction of two bridges. Both were achieved with
the PERI solution.

Parallel bridge

The construction process for the three bridges was similarand essentially only differed in the height at which thesystem combination of the VARIOKIT Bridge System and
VARIO GT 24 Girder Wall Formwork was used. The formwork solution was placed on the bank before the bridge
deck was floated in on the canal. Since the VARIOKIT
system parts are available in different standard lengths,
individual parts did not have to be specially cut to size.
This saved time and material costs on the construction
site. In addition, the formwork performed impressively
with its simple and intuitive handling characteristics during
the shuttering and striking processes. Concreting was
carried out only once on the water; the PERI systems
were transported back to the bank with the help of apontoon after striking.

City on a daily basis. The project required a high degree ofcost efficiency while maintaining a high level of occupationalsafety.

Components from the PERI UP Scaffolding Kit offered consistentsafety throughout the entire works. They were used as accessor shoring solutions, for example as stairways at great heights
or across bridge edges for access to important goods lifts. The
standardised system decks in a 25-cm-grid also allowed for flexible adaptation to a wide variety of geometries during the project.
Another benefit of the PERI solution: A high level of occupationalsafety due to non-slip decks and comfortable step widths.

Sustainable and robust system
formwork for large concreting
sections

Dushyant Sharma ∙ Project Director“The Okhla Sewage Treatment Plant consists of a total of 150,000 m3 of concrete.
Given the enormous amount of concrete, it was not possible to use a conventional
formwork method. For this reason, we decided to use the HANDSET Alpha ­Panel
Formwork, which enabled us to pour large concreting sections ranging from 4.50 m
to 7.00 m in height, as well as 30 m long walls. We are very happy with the result.”

The Okhla Sewage Treatment Plant is located in New Delhi, India, and iscurrently the most capacious plant in Asia. In view of the large concreting
sections of up to 7 m in height and 30 m in length, the customer decided
against using traditional formwork methods involving timber, opting instead for the efficient HANDSET Alpha Panel Formwork.
The construction site covered an area of 104 ha and consisted of several structures that were built according to a very demanding construction schedule andwith a concrete volume of 150,000 m2. Given the exceptional scale of the project,
it was not economical or practical to use cranes. Therefore, a modular formwork
system was needed that could be assembled and repositioned by hand and usedefficiently for different sections over the course of the project. The lightweight
HANDSET Alpha Panel Formwork allowed large concreting sections to be castefficiently in a single pour. In addition, HANDSET Alpha which, in the case of walls,
is designed for a fresh concrete pressure of 60 kN/m², ensured that the work could
be carried out efficiently and with minimum effort. The particularly lightweightmultifunctional panels, weighing 34.5 kg/m2, could be installed by hand with minimal
manpower requirements.
The modular HANDSET Alpha Formwork also stood out for its sustainable use ofmaterials, consisting of only three system components. The robust and powder-­coated HANDSET Alpha panels are reusable, meaning that both the timber used
and the timber offcuts were kept to a minimum. The customer was also impressedby the formwork’s attractive surface finish.
PERI not only supplied the formwork material but also ensured that the formwork
was assembled correctly by providing competent construction site support. The
construction site personnel, who had only worked with traditional formwork methods
up to that point, learned about the benefits of system formwork in no time at all.
The HANDSET Alpha’s straightforward work sequence involving only a few, easy-to-­use components kept the potential for error to a minimum and ensured that the
project ran smoothly.

also resulted in a demanding schedule.

“The success we’ve had on this construction site is a really
positive advertisement for the company VAUBAN GC.
We are already planning the construction of further water
towers using the same method and PERI solutions.”

The reservoir construction work was divided into several sections sothat the resulting loads could be transferred in the best possible way.
A combination of SB Brace Frames, parts of the VARIOKIT Engineering
Construction Kit and MULTIPROP Shoring Towers played a decisive rolein this. The modular design of the heavy-duty brackets was particularly
advantageous, as the connecting parts could be fitted to the brace frames,
meaning no additional parts were required. The way the SB Brace Frames
were anchored in the thin walls was critical in this respect. A double
suspension with suspension shoe was used to distribute the forces.
The PERI engineers calculated the exact forces that would act on thevarious lifting devices in order to determine the required number ofgirders and the best possible arrangement of the horizontal profiles for
optimal load transfer.
PERI’s engineering expertise and the system combination comprising
the VARIOKIT Engineering Construction Kit, MULTIPROP Shoring Towers
and SB Brace Frames played a major role in ensuring that the project wascompleted on time and also ensured a high-quality concrete result.

Not only did this allow theprocesses to be planned and documented in terms of time and space,but all of the information such as requirements/planning data, drawings or parts lists could also be called up at any time in a kind ofdigital scaffolding book.
At peak times, around 1,300 t of PERI system material were in use at
the same time. It was possible to use the PERI solutions in an extremely versatile manner, for example for standing scaffolds, safety
scaffolds, suspended scaffolds, shoring, stairs, material platforms andmobile working scaffolds. Most notably, by combining the PERI UP
Scaffolding Kit with the VARIOKIT Engineering Construction Kit, it
was possible to ensure both geometric and static flexibility thanks to
the metric basic grid of both systems – and thus the highest degreeof working safety.

30 floors of the roughly 50 year old building, which were previously used for administrative purposes and had been
empty for over ten years, have now been given a new purpose: in the course of an elaborate refurbishment project,
the building was completely gutted and transformed into an exclusive urban residential tower with over 300 freehold flats going by the name of “ÜBerlin”. To make the view from the 120 m high tower block even more stunning,projecting and recessed balconies were integrated into the new, modern facade, which is made of glass, steel and

Scaffolding Crew Leader“Even with 22 years of scaffolding experience behind me, I still have a lot of fun
at work. When it comes to being able to
make scaffold adjustments using a system, especially in corner areas, PERI UP
really is the only choice for me. Conventional tube-coupling designs would be
far too time-consuming. The fact that
the PERI UP system is variable at all

PERI UP facilitates

Built at the beginning of the 20 th Century from brickand sandstone, the Church of St. Jacek with its two
57 m high towers graces part of the former mining townof Bytom, not far from Katowice. Inside, murals and a­suspended wooden ceiling adorn the monument. Where
the nave and transepts intersect, a small ridge turretwith a pointed roof juts out.
It was precisely these circumstances that presented thegreatest challenges of this project. PERI had to supply ascaffolding construction that required as little anchoringas possible in the interior and could still be adapted to thecomplex geometry of the structure. In the course of building
information modelling, PERI engineers determined thecorrect number of scaffolding elements with high accuracy

be saved right from the start.

and the bridge piers made of natural stone andbricks, and, at the same time, to restore the track
supporting structure and the drainage facilities.
The shoring structure and the standing and suspended scaffolds were constructed on the basis of
the PERI UP Scaffolding Kit as well as the rentablecomponents of the VAROKIT Engineering Construction Kit. Both systems can be combined
seamlessly on account of the standardised, metricbasic grid. It was possible to adapt the systems
to project-specific geometries and loads in 25-cmincrements without any issues. The scaffolding
was erected in alternation: While the shoring andworking scaffolds for the superstructure were
held available on the west side, the standing andsuspended scaffolds were used to carry out the
facade work on the east side. The switch wasthen made later on.
