Wall Formwork
EN_Bogen_3.indb 32

Wall formwork was originally comprised of squared timbers
and boards. This has resulted in modular systems which­feature a very wide range of applications and a long service
life. Based on the respective construction, a distinction ismade between girder wall formwork and panel formwork.

Girder wall formwork can be individually adapted to matchcomplex forms and high loads and is, therefore, ideal for­architectural concrete structures, for example. Panel formwork
with frames made of steel or aluminium has considerably­fewer individual components and facilitates fast forming oflarge surfaces. In addition, the possibility of moving larger
units by crane greatly accelerates formworking operations.

Slab formwork essentially consists of a horizontal load-bearing
structure which supports the formlining and transfers the forces
into the shoring. This construction allows easy adjustment to­accommodate different loads and ground plan geometries. Modern
modular slab formwork systems comprised of panels or girder grids
facilitate fast forming operations due to a minimum of individualcomponents and a systematic assembly sequence. For filler areas,
complementary system components provide quick and reliable execution solutions. In addition, prefabricated slab tables provide a very
high level of safety, especially at slab edges, and accelerate shuttering times for large areas.

EN_Bogen_6.indb 80

Shoring is a temporary structure that transfers loads during various­stages of construction. It supports, for example, formwork until the­concrete has reached its load-bearing capacity, or transfer loads fromcomponents and equipment during the construction, maintenance ordemolition of structural works. The requirements placed on shoring­systems are diverse; load-bearing capacity, assembly height and adaptability are just as important criteria as individual component weights,
as well as the possibility of integrating working areas and access means.

Scaffolds
EN_Bogen_6.indb 92

Work and safety scaffolding serves to create higher-positioned
working areas for construction site activities, on buildings and on
industrial facilities. It protects construction personnel against­falling as well as unfavourable weather conditions. Furthermore,
platforms and safety scaffolding are frequently installed to­protect site personnel working below, or the flow of traffic from­falling components or objects. While frame scaffolding is aimed
at ensuring a high tempo for 3D scaffolding construction, modular scaffolding with nodal points for connecting ledgers, brackets
and other components provides a very high level of flexibility ­for facilitating geometrical adjustments. Project-specific requirements can be realised with individual planning solutions.

Climbing Technology
EN_Bogen_8.indb 112

Climbing systems are used for the construction of vertical as wellas inclined structural elements at great heights, e.g. high-rise­building walls, bridge piers and dams. When brackets, platforms
and formwork are connected to create securely assembled units,
they can be lifted as one single unit into the following concreting
section after striking has been completed. With the traditional
crane-climbed formwork, units are moved by crane and attached
to climbing anchors which have been concreted in advance. If a­hydraulic climbing device lifts the units to the next storey, then thisis called self-climbing formwork.

For different building shapes and tasks, optimised system variants
have also been developed: climbing systems for facade areas, building cores and shafts, as well as inclined bridge pylons. Climbing
protection panels, which serve as a wind shield and anti-fall protection, complete the product portfolio to ensure safe and comfortableworking conditions at great heights.

Engineering Services
Individual planning and advice for customised formwork
and scaffolding solutions

Around 1,300 PERI engineers worldwide plan and design formwork and scaffolding
solutions for cost-effective executions. All PERI Engineering planning services are
aimed at ensuring that PERI formwork and scaffolding systems in construction operations are always used in line with time, cost and quality standards. The basis forthis is the execution plan records, which are based either on 2D-views and sections
or realistically visualised 3D building models. As a result, technical solutions are­developed with customers that optimise the use of materials and the construction
process itself.
These planning-related services from PERI Engineering are supplemented by verifiable, static calculations as proof of stability for formwork and scaffolding operations,as well as by project-specific installation and assembly plans for the professional implementation of special applications. Construction site personnel can use the plans
to assemble the individual PERI components correctly and prepare them for use.
PERI also provides an extensive range of customised formwork for the constructionof complex, multi-curved reinforced concrete components. To this end, specialists
plan and realise accurately designed three-dimensional formwork units based on a
3D building model.

BIM Building Information Modelling
Planning and management of all construction processes –from the first idea to building operation

When it comes to BIM, PERI has been one of the leading
companies in the industry for many years now and can already show a number international project references thathave been successfully developed with customers using BIM
principles. Through the additional integration of the time andcost factors, the 3-dimensional visualisation of the planning
gradually turns into a 4D or 5D model. Additional processdata relating to formwork and scaffolding technology, such as
required plan changes, automated collision checks, safety
checklists and QR codes for object navigation, are documented and tracked in a mobile building information management
system. All relevant data is available on the construction site
via tablet solutions for day-to-day operations.

With the plug-in Library+ for REVIT, the PERI component catalogues ofthe MAXIMO and SKYDECK formwork systems can be integrated into
the planning for the Autodesk ® Revit ® software for BIM.

The components of the most important PERI wall, slab and column formwork systems are available in Trimble’s Tekla Warehouse and, equippedwith the corresponding metadata, facilitate BIM-related reusage in theconstruction process.

BIM Life cycle

The most important advantage of BIM lies in the fact that planning and design­variants of the 3D building model can be simulated at a very early stage of the­project. In this way, it will be visible to all parties involved where, when, why and at
what cost can interface problems arise – in the planning of the building and in thesubsequent construction work. This future-oriented optimisation of the construction
process offers clients, as well as all parties involved in the construction, transparent
project management and a high level of planning reliability.

“Viertel Zwei - Rondo” Residential Complex, Vienna, Austria

New urban architecture ina tight construction cycle
Horst Höfer Project Manager“Thanks to the high level of expertise and tremendous commitment of the PERI
­engineers, a technically and cost-effectively atractive solution could be found tomeet all challenges.”

The up to 33 m high Rondo Towers feature staggered heights of 4 to 10 floors.
The living area behind the striking exterior view with wide cantilevered, curved­balconies is based on rectangular, interlaced building structures.
The buildings were realised exclusively as concrete constructions. For the shared
11,500 m² basement area containing the parking spaces along with the Rondo
Towers, a construction period of only 10 months was scheduled. PERI therefore
developed a concept that decoupled the respective work operations on the various
in-situ concrete areas. As a result, the construction team was able to work simultaneously on the balconies, walls and slabs thus saving time. The structurally demanding balconies were realized using MULTIFLEX girder slab formwork. This was
supported on MULTIPROP aluminum slab props which were connected with MRK
frames to form shoring towers in order to transfer the load across all levels down
to the slab of the underground garage.
Notwithstanding the above, the walls of the living area were constructed using
TRIO 330 panel formwork and climbed in advance with the help of FB 180 folding
platforms. The slab formwork was realised by means of lightweight and quickly­assembled SKYDECK panels whereby striking operations were particularly fast due
to the drophead system – the cycle times were thus decisively shortened. A highlevel of safety was guaranteed through the use of end-to-end PROKIT anti-fall­protection on all storeys.

Rondo is a building ensemble consisting of 7 residential towers with a total of 200 apartments in
the Second District in Vienna’s Leopoldstadt – ­a development project that combines housing,­living and working in accordance with new criteria.

28.02.19 12:29

If a sophisticated architectural concrete appearance is the business cardof a company, the formwork solution for its own office complex mustalso be of a very high quality. With MAXIMO panel formwork, the joint
and tie arrangement became the means of design.

Kopp, a family-owned and run company based in the Upper Swabian town ofEmerkingen near Ulm, has built up a strong second business division in recent
years with its concrete cosmetic operations. With around 50 employees, thecompany has in the meantime made a name for itself as a competent partner
for the protection, preservation and embellishment of architectural concrete
structures. Completed in 2017, the two-storey office building reflects the highcompany standards in an accentuated and high-quality execution of an in-situ
concrete construction.
PERI formwork specialists were already involved at the planning stage. The
cube-shaped construction exemplifies in its design an accurately sub-divided­arrangement of the formwork areas based on the 30 cm grid pattern of the
MAXIMO panel formwork. Windows and doors were integrated into the­specified surface-area grid without requiring any obstructive filler elements.
MAXIMO with its one-sided tie technology allows precisely positioned joints
and centrally-arranged anchor holes; facade and interior walls show the creative
possibilities of architectural concrete in its fine, smooth surface and monochromatic colour structure. Following customer requests, the MAXIMO elements
were fitted with new formlining – this was the only concession in a project thatwas otherwise realized cost-effectively with rental formwork consisting of
MAXIMO standard elements.
This project was an exemplary demonstration regarding the importance of close
cooperation of architects, contractors and PERI engineers in the construction ofarchitectural concrete structures which covers all planning and execution processes. On this basis, the formwork solution can be optimally adapted to matchthe respective construction project requirements – from standard through tocustomized formwork.

The new school and community centre in the district Antinkangas in the historic town of Raahe on the Finnish Baltic Sea coast is a major project for the small
community. In order to realise the special building geometries, the planners­selected an in-situ concrete construction as the best technical and mostcost-effective solution for the shell construction. Moreover, to ensure that the
project could be completed according to the planned construction schedule,
concreting work had to be carried out in the autumn and winter months. PERI
was able to offer the required formwork solution using the MAXIMO MXH
heated formwork system.
At a very early stage, PERI supported the contractor regarding the use and ­cycle
planning of the formwork and with the integration of prefabricated concrete
components into the in-situ concrete construction. In particular, calculations forthe required large wall heights of more than 5 m without any horizontal sub-division, i.e. in one pour, proved to be a challenging task.
With the MAXIMO MXH, PERI offers a system supplement that allows thewall formwork to be used equally well in summer and winter. The MXH standard and extension heating elements can be adjusted to a set point from 20° C
to 80° C and can maintain this even if outside temperatures clearly fall below
freezing point. In spite of the special equipment with the heating elements andthe required control devices, the time-saving handling of the formwork does
not change: MAXIMO MXH can also be pre-assembled on the ground while tie

EN_Bogen_12.indb 182

In times of increasing populations and gigantic metropolitan
regions, high-rise buildings and towers have become established features of our cities. Limited living space and moreadvanced technologies lead to ever more new height records
and ever more unusual building constructions.

PERI ACS Self-Climbing Formwork was used in the construction of the Petronas Twin Towers in Malaysia, which for anumber of years was the tallest building in the world. When
work on the structures was completed in 1998, the 452 mhigh Twin Towers enjoyed top ranking of the world’s tallest
buildings, forming the pinnacle of high-rise construction.

PERI supported the rapid construction progress with customised
engineering services, competent support throughout the entire
construction phase and just-in-time deliveries of the required­system equipment.

Michael Tahan Project Manager“For such a major project, I wanted to work with a market-leading partner. The professional
solutions provided by the PERI engineering team made the construction of both buildings
far more efficient, safer and faster.”

The Young Towers are two elliptical-shaped residential towers in the centre of
Tel Aviv. The construction of the 40- and 46-storey buildings, as well as the
structure connections at the top and bottom, had to meet extremely high quality requirements. When constructing the shell of the buildings, the amount of
crane time also had to be reduced, and safe work procedures to be guaranteed.
The most cost-effective implementation solution proved to be the combinationof CB Crane-Climbed Formwork for the building cores and an enclosure of thestandard floors with a hydraulically climbed RCS P Climbing Protection Panel.
For the protected working areas to be provided on all storeys, PERI engineers
designed a project-specific RCS climbing variant with wall formwork suspended from a gallows construction.
The rapid construction progress was supported by the use of the SKYDECK
Panel Slab Formwork. Its system-specific fast installation sequence could also
be maintained at great heights, as the upper working levels under construction
were always completely closed off by the RCS Climbing Protection Panel. The
enclosure served as protection against falling and reliably shielded the working
areas from the effects of the wind and weather. As a result, the quality of execution was enhanced and productivity increased due to the increased feeling ofsafety.

A new landmark combines Tallinn’s tradition and modernity.
PERI planned and supplied a climbing formwork solution, which
also took into account the demanding construction schedule andthe tight space conditions.

Laivo Pallav Project Manager Concrete Construction“With this project, construction progress was very quick with the RCS as formwork
scaffolding and protective panel. The mobile hydraulics allowed us to climb in any
weather and at all times – we would often have been unable to use a crane in thestrong winds. For us, PERI is a very reliable and competent partner.”

A 110-m-high skyscraper is the new landmark in Tallinn. It is part of a complex
which comprises new high-rise buildings and restored architectural monuments, connecting the historical heart with the modern part of Tallinn, the­Estonian capital. Centrally located in the heart of the city, the Maakri-Kvartal
business complex has a total area of 36,000 m². PERI developed and suppliedcorresponding comprehensive formwork solutions for the new buildings as wellas the refurbishment operations. In particular, by using climbing technology forthe highest of the three new structures, the PERI team were able to support
the fast construction progress.
The biggest challenge for the engineers was to maintain the very tight construction schedule while, at the same time, accommodating the limited craneand storage capacity in the densely built-up urban area. Here, the RCS Rail
Climbing System combined with MAXIMO Panel Formwork showed its real
strength: the units were raised safely and quickly in increments of 50 cm bymeans of mobile climbing hydraulics. Even the strong winds from the Baltic
Sea could not hinder the climbing procedure, because the climbing units werepermanently attached to the building at all times. The variable assembly alongwith the 125-mm hole arrangement of the climbing rails also made it possible
to adapt the working platforms perfectly to suit the respective height of thestorey.
The MAXIMO Panel Formwork was used not only on the climbing formwork
but also for various other wall areas. It ensured fast shuttering times, the best
quality concrete surfaces and a regular joint and tie pattern. When forming thefloor slabs, the SKYDECK Panel Slab Formwork made a convincing case due toits systematic assembly sequence without any time-consuming measuring.

Graphic: Raumgleiter

Visionary living arrangements with extensive green terraces have been realisedwith the construction of the 70 m high Aglaya garden tower block near Zurich,
which houses not only 85 condominiums, but also office and commercial
space.
From the 5th floor, the building features an 18-m-high funnel-shaped widening.
PERI UP shoring towers were used to support the prefabricated concrete­elements used for this, which simultaneously served as working platforms.
The towers also transferred the loads from the geometrically complex in-situ
concrete beams and from the slabs above. A VARIOKIT truss construction
served as a support for the diagonally arranged components and to secure theposition of the assembly.
The team also had to realise the staggered design of the cantilevered balconies,
which project up to 4 m from the building. For this, the PERI solution stipulated
the use of project-specific framework-type tables based on the VARIOKIT­Engineering Construction Kit and MULTIPROP shoring towers. On the one
hand, the use of rentable system components was very cost-effective; on theother, the pre-assembled slab tables delivered by PERI minimised valuable­assembly times on the construction site. Thanks to double-capacity on-site­material volumes of the MULTIPROP sub-structure, the slab tables were usedextremely efficiently and, as working platforms with protection panels, provided
a high level of safety even when working at great heights.

At the time of its completion, the 462 m high Lahkta Center in
St. Petersburg was the tallest building in Europe. PERI planned and­supplied formwork and scaffolding systems to realise the architecturally
striking building located directly on the Gulf of Finland.

Faruk Gökçe Başaran Chief Engineer“The biggest task was the planning of the appropriate systems with which we wereable to implement both the architectural design and safety requirements, as well ascomplying with the construction schedule. The PERI systems are designed with thefocus on ensuring high quality, work safety and efficient working operations. PERI
thus played a key role in the construction of the Lakhta Center.”

The Laktha Center, designed as an interconnected complex in the form of abusiness centre right on the Baltic Sea, has around 400,000 m² of usable floor
space. From an architectural point of view, the main challenge in constructing
the skyscraper was realising the continuous, spiral-shaped rotation, along withthe subsequent constantly changing slab areas.
The particular requirements for the foundations required a project-specific special solution. The structure is positioned on 264 piles that reach a depth of up to
82 m PERI designed a comprehensive solution based on the DOMINO Panel
Formwork to construct the foundations which rest on these. Concrete totalling
19,624 m³ was poured in one concreting operation and entered the Guinness
Book of Records as the biggest continuous concrete pour ever carried out.
Together with the contractor, PERI Russia developed an integrated, geometrically flexible solution to form the core of the building and the cantilevered slabs.
The VARIO GT 24 Girder Wall Formwork in combination with the ACS
Self-Climbing System could be moved quickly and independent of weather conditions without using a crane. Due to the exposed location by the sea, particularly high wind loads had to be taken into consideration for the end-to-end climbing
protection panel solution, which was based on the RCS Rail Climbing System.
The round-the-clock technical support and the planned and supplied formwork
and scaffolding solutions from one source facilitated very efficient project management and fast implementation, including when changes had to be made atshort notice.

Combined climbing formwork
for special twisted architecture
Alfio Musumeci Technical Director
Tommaso Salvo Site Manager“Our aim is to always find the right balance between technology and cost-effectiveness. Together with the PERI engineers, we developed the best way to realise
the tower at the right price. Ultimately, we were able to complete the requiredbuilding work well before the end of the agreed construction period – to the greatsatisfaction of our client.”
Realising a structure that is architecturally interesting and statically still­feasible also makes the planning and structural implementation a challenging task. The Generali Tower on Milan’s Piazza Tre Torri, the new administrative headquarters of the insurance group of the same name, is a good
example of this. The 170 m high office building elegantly winds its way­upwards and features changing slab geometries on each floor. These­revolve around the centrally positioned core of the high-rise building withcircular and angular external walls, whose thickness tapers to one third of
the original 90 cm as the height of the structure increases.
For the core of the building, RCS formed a combined climbing formwork
solution together with a self-climbing ACS Platform Unit, as well as craneclimbed CB Climbing Platforms and BR Shaft Platforms. In addition, the
ACS technology allowed the concrete placing boom to be moved upwards
without the use of a crane. SKYDECK Panel Slab Formwork with its drophead system was selected to shutter the floor slabs. The RCS P Climbing
Protection Panel secured all leading edges. The closed enclosure enhanced
work safety levels and avoided any weather-related downtime.
The project-specific and perfectly coordinated PERI formwork deployment
facilitated consistently safe and, therefore, fast work processes. As a result, the standard floors were realised in a continuous weekly cycle despite
the complicated building geometry. With the shell construction taking just
17 months, it was possible to finish ahead of the originally planned schedule by a full 3 months.

For the elliptical Möbius Towers in Brussels, which was realised in two
construction phases, the PERI climbing formwork solution facilitated fast
execution times. Valuable crane time was reduced and the tight construction schedule could comfortably be maintained.

Philippe Vandenberghe Project Manager“All elements that could be pre-assembled were delivered to the construction site
ready for use. After assembling the climbing system, shuttering operations could becompleted in a very short time. The technical support provided by PERI was absolutely
outstanding.”

The architectural design of the almost identical twin towers is based on a
­Moebius strip. The 20 th and 24th storeys of both structures feature an ellipticalground plan. To ensure the shortest possible construction time, PERI developed
a formwork solution that took into account the limited crane availability, especially as regards the construction of the building cores, which were realised in­advance.
The RCS Rail Climbing System was combined with different system formwork:
PERI supplied prefabricated formwork elements based on the VARIO GT 24
Girder Wall Formwork System, which were used to shape the rounded external
walls of the core. MAXIMO and TRIO Panel Formwork, in combination with
RCS, proved to be a big advantage with regard to crane-independent forming of
the internal walls. In addition, TRIO, DOMINO and RUNDFLEX served as wall
formwork for the concrete structural components, which were subsequently
concreted for the climbing formwork.
System use was customised to the specific project and this, combined with therail-guided, hydraulically operated RCS climbing technology, facilitated fast cycle
sequences. Aided by the extensive range of PERI support, along with a high­degree of prefabrication, the storeys could be completed in regular 7-day cycles.

the avant-garde appearance typical of Zaha Hadid. The 140-m-tall high-risebuilding is positioned on a narrow rectangle to leave room for a historic buildingthat provides a direct connection to the lower storeys. From the tenth to the
31st top floor, the structure expands its ground plan in a distinctive twist.
The RCS Rail Climbing System served as climbing formwork for the buildingcore realised in advance, as well as for enclosure and anti-fall prevention for thework being carried out on the subsequent building shell floors. The lightweight
RCS CL Climbing Formwork, together with VARIO GT 24 Girder Wall Formwork, formed hydraulically climbed moving units, thus requiring only a minimum of crane capacity. The PERI implementation solution was supplemented
by RCS MP Landing Platforms which were used for moving and intermediatestorage of formwork materials.
Execution of the floor slabs, including beams with lightweight PERI DUO­composite formwork, was an important success factor on the construction
site. The system is also characterised by its low weight and particularly easy
handling when forming the walls. Work operations were totally enclosed bymeans of the RCS P Climbing Protection Panel, thus providing complete­protection against falling and the sometimes very strong winds.

Groundbreaking architecture
for Amsterdam trade fairs
With 25 storeys and 650 rooms, the nhow RAI is the largest and tallest hotel inthe BeNeLux region. Its bold architectural design was realised cost-effectively
with the help of the PERI formwork and scaffolding concept.

The design for the new nhow hotel bears the signature of the renowned
architect Rem Koolhaas. The iconic 91 m high structure at Amsterdam’s
RAI trade fair centre is divided into three blocks, each with a triangular
ground plan and arranged obliquely in relation to each other. On the 10 th
and 17th floors, the storeys cantilever outwards up to 12 m.
In order to safely transfer the loads of the cantilevered building segments,
PERI developed a supporting structure based on the VARIOKIT Engineering Construction Kit. Here, the VRB Heavy-Duty Truss Girder, which ismainly used in bridge construction, transferred the high loads until the­level of self-supporting capability was reached in the completed storeys ofthe building shell. The cantilevered support and working platforms meantthat a complex birdcage scaffold solution was not required and accelerated
the construction process.
The core of the building was constructed in advance using the ACS andRCS Self-Climbing Systems – crane-independent and, in combination with
the MAXIMO Panel Formwork, ensuring a fast climbing sequence.
SKYDECK Panel Slab Formwork provided twin benefits when forming thefloor slabs: the systematic assembly sequence with lightweight systemcomponents accelerated shuttering and striking operations. In addition,
the slab soffits could remain visible thanks to the uniform panel grid­arrangement.

When the museum itself­becomes a work of art
The Scottish coastal formations influenced the Japanese star architect Kengo
Kuma with the design of the museum. The outer shell of the building with cantilevered panels made of prefabricated concrete elements features black surfaces
in the highest quality of architectural concrete. In order to realise this building
structure in concrete, it required formwork and logistics solutions at the highest
level.
Carey’s Civil Engineering was commissioned to carry out the concrete work anddecided in favour of PERI UK to produce the free-form formwork and shoring
solutions for the exterior walls of the building. Before the start of the project, amodel of a formwork element with selected formwork and with designated curvatures and inclined surfaces was produced. Concreting tests showed that therequired geometry, surface texture and pigmentation could be realised and­confirmed that the load support functioned and striking operations would be
problem-free in spite of the unusual shape.
For supporting the massive concrete segments, a 3D model was designed by ateam of experts from Arup. This simplified estimating the amount of shoringand supports which were required to carry out the execution. PERI UP was theideal shoring system for supporting the walls. The height of the shoring system
could be adjusted step-by-step in 250 mm increments thus allowing optimum
access to the widely varying concreting heights throughout the building. PERI
created the formwork variable depths and heights which consisted of VARIOGT 24 panels and VARIOKIT components – tailored to match the artistic twists
and turns of the building structure.
For engineering, formwork production and logistics, PERI UK combined its own
capacities with the expertise and experience of the 3D experts from Weissenhorn. The good coordination of all parties involved was crucial because at thepeak of the project, Carey’s Civil Engineering required 1,000 m² of customised
formwork elements per month from PERI.

2,400 m².
In addition to the very tight building schedule, a large part of the concrete­construction was to be realised in architectural concrete quality. Constructedusing SKYDECK Slab Formwork, the slab alone featured a 2,000 m² architec­
tural concrete surface when it was completed. In the edge areas of the slabs,
MULTIFLEX Girder Slab Formwork was used to great effect. The support
with PERI UP Flex scaffold towers created a flexible solution with a high­load-­bearing capacity – ideal for executing the up to 3 m cantilevered slabs inheights up to 12 m.
For realising the large circular entrance hall, RUNDFLEX Wall Formwork was
selected. The pre-assembled elements could be easily and quickly adjusted onsite in order to match the required radii with the help of the provided templates.

Casino and Congress Centre, Cap d’Agde, France

High level of productivity­despite high architectural­concrete requirements
Simon Mercier Site Manager“We decided in favour of custom-made VARIO Formwork.
The decisive factor here was that we wanted to have excellent surface quality
while maintaining a high degree of productivity especially for the white architectural­concrete surfaces. We are all very proud of the results.”

The resort on the French Mediterranean coast of Cap d’Agde is undergoingmodernisation in order to also retain its attraction to tourists in the future.
The facades of the casino and adjacent likewise new congress centre radiate
in refreshing elegant white and are representative of the redesign of the wellknown holiday destination.
The architectural concrete surfaces of the two buildings had to meet the highest quality requirements. The outer shell was realised with the help of VARIOGT 24 Girder Formwork. The formwork elements were pre-assembled at the
PERI assembly facility and delivered to the construction site as ready-to-use
6.60 m and 4.80 m high modules which also included the working platforms.
In order to be able to form the external walls – in part, up to 17 m high –the ­project management team decided to use VARIODECK Slab Tables on­MULTIPROP Shoring Towers to support the girder formwork. As a result, a
support structure using standard components was possible in spite of thecurved walls. PROKIT anti-fall protection provided safety at the leading edges.
For realising the slabs, SKYDECK Panel Slab Formwork was selected which
was likewise supported on MULTIPROP aluminum props. Thanks to the highload-bearing capacity of the system, slabs up to 50 cm thick could easily beformed which allowed the execution of all slabs to be carried out with just one
system.
The challenge when forming the internal walls of the building was ensuring aContractor

PERI provided valuable support for the reconstruction of a destroyed
church. Particularly challenging was to replicate the numerous domes andspandrels of the building exactly according to its historical predecessor.

Darcheev Anton Project Manager“The task of completely rebuilding the cathedral in such a short time seemed unrealistic.
Thanks to the technically versed and well-coordinated work provided by PERI, we wereable to meet the construction deadlines. Today as well as looking back on what we haveachieved together, we can say with certainty that the PERI team works with absolute­professionalism in its field.”

The model is historical while the construction is very modern: after its destruction in 1932, unfortunately only drawings exist of the Cathedral of the Virgin ofKazan in the eponymous capital of the Russian Republic of Tatarsan. Now, thechurch with its numerous small and large domes of up to 15 m in diameter has
been replicated in concrete based on these drawings.
A large part of the formwork was delivered pre-assembled to the jobsite, notonly to reduce the workload for the construction team on site but also to replicate the arched structures and dome vaulting as accurately as possible. Formwork for larger structures, such as the domes, were constructed on the basisof the VARIOKIT Engineering Construction Kit and positioned on PERI UP­shoring towers. Above all, the large 3D formwork boxes for the up to 7 m highspandrels, curved in all room dimensions, between the round arches anddomes had to be accurately assembled. For connecting the corners of theformwork boxes, PERI provided its individually developed solution in order toensure that error-free installation was as easy as possible to carry out.
For construction of the recurring forms, the formwork was used multiple times
and moved with the crane. For each formwork box as well as every dome formwork assembly, a separate dismantling plan was included in order to preventany damage and to minimize the time and effort required for the moving procedure. In addition, PERI specialists were constantly on site throughout the entire
construction period of around 9 months – alongside the precisely pre-assembled formwork elements, one of the success factors of the project.

Formwork and scaffolding fora museum built as a memorial
Adam Szkudlarek Site Manager“For realising the museum with its complex geometry and featuring a mostly architecturalconcrete design required an individually adapted formwork solution. Perfect delivery logistics
along with the readily availability of the required formwork and scaffolding played an important role in the implementation. Once again, PERI proved to be a reliable partner on the­construction site.”On the former site of the Gdańsk public transport company, a prism-shaped
structure emerges from the ground at an oblique angle. The highly visible,­almost 41 m high tower houses – together with a second, one-storey building
structure – the Museum of the Second World War.
In addition to the unusual geometry with the inclined building walls, a largepart of the concrete surfaces was to be realised in architectural concrete quality. PERI engineers worked closely together with the site management team
to develop a formwork solution based on VARIO GT 24 Girder Wall Formwork
combined with VARIOKIT system components. As a result, the anchor positions could be freely selected and the individual elements could be seamlessly joined together. Working platforms based on the VARIOKIT Engineering
Construction Kit guaranteed work could be carried out extremely safely on
the inclined walls, also at great heights. TRIO Panel Formwork with integrated
working platforms was used to construct the straight internal walls some ofwhich reached a height of 14 m.
Used as shoring and stair access means, the PERI UP Flex scaffolding system
ensured quick and safe construction progress when realising the shell of thebuilding. In addition, the modular scaffolding – in its function as working scaffold – could be optimally adapted to match the complex geometry of the­building so that working at a height of 40 m was safe and comfortable forconstruction team personnel. VARIOKIT bracket constructions integrated into
the scaffolding solution allowed separate individual scaffolding segments tobe separated from each other, thus increasing the cost-effectiveness of thesolution.

The work on the new UTS building was significantly accelerated through a­project-specific formwork solution. In addition, specially installed LPS meshenclosures also provided the highest possible level of safety during the­construction process.

Travis Carter Project Manager“The PERI team provided us with excellent support during the conception phase,­including tests on true-to-scale models in the original size. The PERI solution not only
worked perfectly, it also fulfilled all safety standards.”

On the UTS campus – University of Technology Sydney – a new building was­realised featuring a total of 17 storeys whereby the top 10 floors formed a­tower with rounded floor slabs positioned against each other in a twisted­arrangement. The multi-functional building provides everything that the­university needs to operate on a total floor area of 47,000 m²: lecture halls
and seminar rooms, libraries and working spaces through to catering areas.
For forming the walls and columns, MAXIMO Panel Formwork was used.
The elements were completely pre-assembled on the ground and positioned
as one unit with the crane. The quality specifications for the architectural­concrete, which were so important for the success of the project, were easily
met with MAXIMO, also through the regularly positioned anchor points.
Another task proved to be a major challenge: the floor slabs of the shell structure were to be clad in a protective wall in order to be able to begin early withsubsequent work operations such as finishing work on the facade. A standard
solution could not be used due to the curved, counterposed and outwardly­tapered shape of the slabs. Together with the contractor, PERI developed a
special construction consisting of slab tables with permanently mounted LPS
mesh enclosures for the two upper storeys respectively. After the feasibility
was verified in a series of tests, this solution was used very successfully in the
project. With a lifting fork specifically adapted to suit project requirements, theslab tables could be lifted two floors and then re-positioned.

MULTIPROP slab props and heavy-duty spindles
taken from the VARIOKIT Engineering Construction Kit were used for supporting the wide cantilevered areas in the bottom storeys.

for inclined pylons
Sachin Kotarwar Project Manager“The PERI system allows work to take place on 3 levels simultaneously. The working
platforms have sufficient space and can be easily and accurately adapted to suit therespective site conditions. The systems are very flexible and practical for use at allheights.”

The Mahatma Mandir in Gandhinagar in the Indian state of Gujarat is not only aconvention and event centre but also a memorial site for Mahatma Gandhi. The
visual appearance of the almost 14 hectare site is characterized by two highly
visible pylons which tower over the entire complex. These hold the support­cables of a suspension bridge that spans a very busy road and connects thecongress centre in the east with the museum in the west.
The SCS Climbing System was used to form the inclined, 85 m high pylons.
With this system, the loads resulting from the fresh concrete pressure aretransferred via the brackets into the previous concreting section by climbing­anchors whereby the formwork is securely anchored at all times. All work
­operations are therefore carried out easily and safely – also at great heights.
The climbing formwork used had three levels, each with a spacious working
platform. The wide platforms facilitated smooth construction progress for thesite workforce. Also for the 15-degree pylon inclination, the SCS platforms

ACS for pylons reaching­dizzying heights

Three pylons carry the around 1,000 m long bridge superstructure across the River
Mersey. For supporting the superstructure, the highest pylon widens at a height ofapprox. 20 m from 6 m to a total of 17.5 m. At this point, hammer-head and pierhead formwork were used.

The new six lane, more than 2,000 m long
­Mersey Gateway Bridge with its three striking
125 m, 80 m and 110 m high pylons, provides
considerable relief for the heavy flow of traffic
in the Liverpool region, especially between­Runcorn and Widnes.

For this, PERI´s British engineers developed a concept on the basis of horizontally-positioned SB Brace Frame units that could be coupled together, whereby 7 m
wide working levels were created. At the same time, the brace frames were used
for transferring loads from the cantilevered concreting sections into the pylon
shaft. The respective concreting heights were exactly matched to suit the anchoring possibilities in the shaft section previously concreted while forming took placerequiring around 21 concreting cycles each 5 m high.
The ACS R Self-Climbing System, combined with VARIO GT 24 girder wall formwork, optimised the construction of the upper pylon shaft. The wall formwork wassuspended from the top working platform so that the formwork carriage could­easily be retracted together with the formwork after striking and the top working
platform could then be folded upwards. In this way, generous working areas for thereinforcement work were created. PERI UP Flex reinforcement scaffolding and all
required materials were easily lifted in by crane.
The simultaneous climbing of several units reduced the number of leading edges.
Furthermore, the enclosed working platforms provided additional safety and,at the same time, protection against the high wind speeds as well as rain.

Pablo Fernandez Rodero Site Manager“We decided in favour of PERI due to the guaranteed quality and safety considerations along with a convincing price-performance ratio. An essential part ofthe excellent cooperation was the technical support right from the very start ofconstruction.”

The 1,400 m long, four-lane bridge, spanning the Roskilde Fjord between­Marbæk and Tørslev, shortens the connection between two peninsulas southof Frederikssund. The 10 km long, four-lane expansion highway connection
shortens travel times and takes the high volume of through-traffic away fromthe nearby inner city districts.
The 17 V-shaped bridge piers reach heights of up to 22 m. PERI planned andsupplied the pier formwork for their construction. Form-giving VARIO GT 24
Girder Wall Formwork together with the SCS Climbing System created generously-sized climbing units that could be moved with only a few crane picks.
The low weight SCS is characterised in particular by its high load-bearing­capacity. As a result, the number of anchor points is also reduced – which­ensures an extremely high level of cost-effectiveness.
Access technology based on the PERI UP Scaffolding System ensured quick
and reliable access to the respective working levels which, in turn, accelerated
the overall construction progress. In order to form the foundations and abutments economically, the MAXIMO and TRIO Wall Formwork Systems were
the ideal supplement to the PERI solution.

fantastic job. ALPHAKIT, just like the other PERI systems, is an excellent systemthat allows us to work much faster and easier.”

The ambitious infrastructure project, in the southwest region of the Mexican
state of Nayarit, extends the road network between the mega city of Guadalajara and the Gulf of California. Among other things, it was necessary to build a
433 m long bridge in an area criss-crossed by mountains and valleys. PERI
planned and supplied the formwork and shoring solution for cost-effective­construction of the four-lane structure, despite the demanding logistics dueto the rough terrain.
VARIO Girder Wall Formwork on CB Climbing Formwork was used to realise
the total of four piers up to 48 m high. This proven combination facilitated acost-effective execution of the bridge piers in 4.80 m high concreting sections.
After reaching the planned pier heights, horizontally positioned SB Brace
Frames supported construction of the pier heads.
For the edge areas of the bridge, PERI engineers and the contractors developed
an efficient solution based on the ALPHAKIT System. For this, the materials
were delivered just-in-time to the jobsite to meet the respective construction
phase requirements and mounted on-site to form ALPHAKIT Heavy-Duty Truss
Girders and shoring towers. As a result, the 65 m long construction for the­superstructure build, consisting of heavy-duty truss girder units, could be­realised with a minimum of space and crane time. The outermost 12 m of thecentral bridge section was supported by ST 100 Stacking Towers. This solution
made it possible to realise an 80 m superstructure section in one piece. After
concreting and striking, this section was simply moved into a new position on
the opposite side of the bridge.

New Champlain Bridge, Montreal, Canada

ACS and RCS: the right teamfor cycle sequences
Isabelle Genest Project Manager Pylons“I’m extremely satisfied with the climbing solution and cooperation with PERI.
I would recommend their systems to anyone. Simple application and short­execution time really helped us realise this project.”

The new Champlain Bridge is a 3.4 km long cable-stayed bridge with a striking,approx. 170-m-high concrete pylon and asymmetrically arranged guy ropes.
The characteristic bridge between Montreal and Brossard includes a two-lanerailway corridor, six lanes for vehicles and a pathway for both cyclists and­pedestrians. PERI provided a complete climbing solution for the upper pylon
as well as extensive on-site support.
The RCS Rail Climbing System was used on the inside of the hollow pylon legs,
while the ACS Self-Climbing System raised the VARIO formwork on the outside. The combination of the climbing systems supported the fast construction
progress: both systems could be lifted into the next section using climbing­hydraulics, crane time could be reduced and the 6 m high sections climbed in
12-day cycles. The working platforms remained securely attached to the pylons
during the entire climbing process and provided construction site personnel
with a comfortable and safe working environment at all times.
On the outer side of the ACS system, RCS system protection panel enclosures- pre-assembled on the ground – formed a virtually gap-free protective shield
for the working platforms. As a result, this further increased safety levels and­protected the workers against the sometimes harsh weather conditions highabove the St. Lawrence River.
At the PERI assembly hall, climbing platforms and VARIO Girder Wall Formwork elements were accurately adapted to match the complex pylon geometry
and delivered to the construction site as pre-assembled units. The final assembly took place here in accordance with the detailed PERI general arrangementdrawings under the guidance of an experienced PERI supervisor.

Plaza de Armas Metro Station, Santiago, Chile

Extremely accurate realisationof extraordinary arches
3D free-form formwork was planned for the construction of the curved formwork halves of the central hall roof. Using this made it possible to realise an
extraordinary architectural idea in a very short construction time.

The new Metro Line 3 station concourse at the famous Plaza de Armas in
the centre of Santiago is one of the country’s modern urban development
projects. As a visual and technical engineering highlight, the new structure harmoniously blends into the listed surrounding area and characterises the cityscape of today.
PERI engineers made use of their formwork and equipment expertise to
great advantage throughout the entire construction period. Precision-made3D formwork units designed specifically for the project were used for theindividual shaping of the multi-curved roof structure in a reinforced concrete method. A 3D building model with so-called free-form surfaces
served as the basis for this. At the PERI assembly service facility in Chile,the individual cleats and shaped components were cut using the latest
CNC technology and were then assembled into formwork units in combination with VARIO GT 24 formwork elements.
Due to the downtown location and limited storage space, PERI delivered
the ready-to-use pre-assembled boxed elements just-in-time to the­construction site. Here, they could be connected to form shape-providing

been built in the vicinity that includes a two-story passenger and ferry terminal.
Thanks to the intelligent combination of the different PERI formwork and­scaffolding systems, all specified quality goals and time schedules were­reliably achieved in the project.
The distinctive V-shaped – due to being inclined at an angle to each other –10 m high entrance columns with diameters of 95 cm and 100 cm respectively
were realised in the best surface quality with the help of customised SRS­Circular Column Formwork. System components taken from the VARIOKIT­Engineering Construction Kit facilitated fast concreting of the first 6 m high­sections. In addition, PERI UP Flex served as working scaffold and shoring. ­Its metric 25 cm system grid allowed flexible adjustment to accommodate
the circular columns which were diagonally-positioned across the inside of
the structure.
Different PERI systems were used for the entire terminal building – dependent
on the component geometry and load as well as the required concrete quality.
DUO and TRIO system formwork were used for the foundations, beams, columns and walls. Depending on the geometric complexity and support height,
MULTIFLEX or SKYDECK were selected for constructing the slabs. In turn,
PERI UP Flex proved itself as flexibly adaptable shoring.

The 35 km long combination consisting of bridge and tunnel crosses thePearl River Delta and, since its opening in October 2018, has been connecting the three regions of Hong Kong, Zhuhai and Macao. PERI engineers supported the construction of the approx. 6 km underwater tunnel
with two shuttering machines. The excellent cooperation created confidence in the competence and expertise from Germany for the CCCC
­project management team of CCCC. This benefited all parties later in the
project regarding the construction of the adjoining structures – namely thetunnel portals and two operations buildings – as this allowed the contractors to integrate suggestions for improvements and completely new methods for the execution of the construction work.
On the two artificial islands, which were created for the transition areafrom the tunnel to the respective adjacent bridge, the operations buildings
for the mega transport infrastructure were built along with a number ofother structures. The east island forms the transition area from the immersed tunnel in the direction of Hong Kong. The building on the island
provides, among other things, space for a comprehensive exhibition on thetransport engineering project. The structure on the artificially created­island towards the west consists primarily of the required operating and­utility facilities for the underwater tunnel.

The expertise of PERI engineers in project-specific formwork and shoring planning allowed the execution of the complex geometries of tunnels, entrances and operations building in the highest SB

Reinhold Lintschinger Site Foreman“The MAXIMO was the right system for large wall thickness, high walls and­numerous applications.”

The expansion and modernisation of the sewage treatment plant in Korneuburg
showed the typical requirements for concrete construction when executing
solutions in the water and wastewater structure sector. Since clarifying tanks
must accommodate large volumes of water in a small surface area, high tankwalls and large wall thicknesses are required. In Korneuburg, the walls were up
to 6.50 m high and 55 cm thick.
The PERI formwork solution was mainly based on the MAXIMO Panel Formwork and RUNDFLEX Circular Formwork systems. The elements of both wall
formwork systems could be seamlessly connected with each other by means of
the BFD Alignment Coupler. With the BFD as the only connecting component,
even filler timber compensations and height extensions could easily be realised.
Using MAXIMO, the straight walls could be shuttered through a fast cycle sequence and in high quality. Here, the one-sided MX 18 Tie Technology ensured
fast shuttering times for all wall thicknesses, because no additional site personnel or scaffolding was required on the primary formwork when closing. The
small number of tie points in the MAXIMO system not only further accelerated
forming operations but also reduced the time and expense involved in subsequent sealing measures.
In addition to the high quality requirements and corresponding dimensional­accuracy, strict safety regulations on the construction site had to be observed.
A significant aspect of the PERI solution, therefore, was the use of crane-movable PERI UP Reinforcement Scaffolds and the realisation of anti-fall protection
with the help of the PROKIT Safety System.

With its height of 73 m and 15 m diameter combined with a very distinctive aluminium facade, the Gasperich Water Tower looks like apiece of art set into the landscape. The concrete structure behind it
was realised using a PERI climbing formwork solution.

Pierre-Henry Lejeune Site Manager“Due to the tight schedule and stiff competition, we decided in favour of the RCS­system. The easy and simple handling meant that 3 workers were sufficient to carry out
the shuttering operations. In addition, the safety installations were an integral part of
the assembly and did not have to be adapted to suit the different construction phases.”

Perrard, a subsidiary of the Eiffage Group, was looking for a safe as well as very
­efficient solution for the construction of a new water tower near the town of­Gasperich in southern Luxembourg. The schedule for the construction and­planning phases was extremely tight, while the budget demanded cost-effective,­optimal solutions and, at the same time, there should be no compromise on worksafety. Furthermore, due to its exposed position, the outside of the 73 m high­circular tower had to be realised with an architectural concrete look.
External and internal formwork were based on the RCS Rail Climbing System andsupplemented by VARIO GT 24 Wall Formwork elements which had been adapted
to match the curvature. Using a 3.30 m standard cycle height, only 2 rows of ties
were required, which resulted in significant time savings for shuttering and striking
operations, as well as advantages regarding the waterproof construction.
The RCS system also allows rail-guided climbing with circular walls, so that themoving units are securely connected to the structure at all times by means ofclimbing shoes. On the outside, the RCS climbed independently with the help ofmobile climbing hydraulics, and the internal formwork was lifted by crane.
The PERI solution was completed with the addition of the MAXIMO Panel Formwork for the internal walls and SKYDECK for the construction of the intermediateslabs. PERI UP Flex was used in this construction project as reinforcement scaffold
and as a lightweight site stair tower which provided a flexible access solution.

EN_Bogen_18.indb 268

Industrial construction is one of the few areas in the construction industry in which predominantly functional and economic
aspects determine form. On the one hand, because visual­aspects play a secondary role here. On the other, because
plant facilities are usually extremely complex, so any architectural considerations would simply be too time-consuming andexpensive to implement. In addition, the execution and maintenance of industrial buildings are normally subject to very highsafety requirements.

PERI systems were used in the modernisation of Blast Furnace 9, which is operated by ThyssenKrupp Steel Europe in
Duisburg, Germany. The combination of the PERI UP Flex
Modular Scaffolding with the VARIOKIT Modular Construction
System created optimum working conditions when insulating
the dust extraction system.

OTMS Tank Farm, Saldanha, South Africa

Enormous challenges –­unconventional solution
On the coast of South Africa’s Saldanha Bay, a gigantic crude oil tank farm with
12 underground tanks was realised. Each one has a surface area of 110 × 110 m
and is 17 m high. This large-scale project with a capacity of 13 million barrels, or
2 billion litres of oil, involved moving a total of 1.5 million cubic metres of earthand pouring 150,000 m³ of concrete. For this extraordinary construction project,
PERI developed project-specific implementation solutions at a very early stage incollaboration with the project planners.
Instead of a conventional slab formwork solution with a 17-m-high shoring­system, PERI engineers designed a construction variant borrowed from bridgebuilding using formwork carriages. While the table-like slab formwork could belowered one day after concreting had taken place and moved 8 m into the next
section, VARIOKIT Framework Constructions provided the necessary support
for the concrete slab until it had hardened. With only 7 formwork carriage units,each concreting section realised 880 m² of slab area per tank in regular 5-day
cycles without a crane.
A total of 2,400 reinforced concrete columns with diameters of 50 cm or 60 cm
and 17 m high had to be constructed in advance. On the basis of the SRS Circular Column Formwork, a project-specific solution was developed which was sufficiently stable as an advanced formwork half even at great heights. In addition,
thanks to additional intermediate platforms, they could be cleaned and oiled in astationary position. First tested as a 1:1 prototype and optimised right down to
the last detail, one formwork set on average was concreted on-site every second day.

At BASF’s largest investment project, an innovative scaffolding concept
based on the PERI UP Flex Scaffolding System, in combination with
BIM, ensured significant time and cost savings – and also set highstandards regarding work safety.

With a capacity of 90,000 t per year, the plant has replaced an older, less-productive facility and operates in accordance with the world’s most efficient­production processes. Acetylene is an important intermediate product and isused as a central source material for around 20 production plants at BASF’s
Ludwigshafen site.
It is not just the new plant work that works with the world’s most modern­technical facilities and processes. During the construction, modern planningand working methods were also used – this formed the basis for assembly
work operations remaining on schedule. Up to 1,300 people were working at
peak times on the jobsite, which covered an area of around 55,000 m² – theequivalent of almost eight football pitches – and had an installation height of up
to 90 m.
In order to install the plant technology efficiently and safely, which featured
more than 400 machines and pieces of equipment along with a 90 km longpipe system and electrical installations, the PERI UP Flex Modular Scaffolding
System was used in the second construction phase. New working levels andaccess means were realised for construction and assembly work on an almost
daily basis.
The central project approach was based on the combination of BIM methodology for the planning and execution, and high standards of work safety. The jointly
developed, innovative scaffolding concept provided the basis for a comprehensive overall solution for efficient scaffolding construction management, 3Dplanning, cross-trade coordination and execution, in order to minimise planning
time and costs. With its 25 cm grid in combination with VARIOKIT system components, PERI UP Flex thereby ensured excellent adaptability and occupationalsafety at a very high level.

High degree of safety

Ron Fontenot Site Manager“By combining the PERI scaffolding with the Integrated Scaffold Program provided
by PERI, we are able to complete our tasks faster and with less site personnel.
This reduced the total man hours of the entire project. This combined system is atremendous cost saver in all of our projects.”

Just considering the sheer size of the $5 billion ethane cracker at Chevron
Phillips Chemical, with a targeted production output of 1.5 million tonnes,
is extremely impressive. The complexity of the facility is also highlighted
when looking at the amount of steel that has been installed along with thecontinuously winding pipelines. For the construction, it was necessary toprovide workers with secure access means at all points. On the one hand,
this required an enormous amount of scaffolding materials. On the other,
it is important for projects of this size that all relevant information regarding
the scaffolding components is constantly available.
The Integrated Scaffold Program (ISP) from PERI encompasses the 5D PERI
Path software program and facilitates early cost estimates, operational planning and materials management as well as planning on-site material requirements in advance. In Baytown, the software monitored the use of around
750,000 scaffolding components and all related work considerations. The
data allowed a detailed analysis of the working hours to be carried out andprovided enormous transparency. As a result, it was possible to plan in moredetail, reduce labour and logistics costs, and more effectively manage­scaffolding operations.
The PERI UP Flex scaffolding system used was able to accurately follow thenumerous cylindrical reactors and countless pipelines as well as providing
the highest level of safety for all site personnel throughout the entire­construction process. The addition of GT 24 formwork girders facilitated acost-efficient solution for realising temporary support for the installation of

8 months of construction work.

Markus Diebold Site Foreman
Daniel Ocker Project Manager
Andreas Banzhaf Site Foreman“Our construction project with simultaneous building shell work and different cross-sectional
dimensions was extremely complex. Due to the intensive cooperation with PERI, we wereable to maintain the tight schedule whilst taking into account all safety requirements.”

The construction of a new 140-m-high heat exchanger tower was an importantelement of a radical modernisation project at the Schelklingen cement plant.
Constructed in reinforced concrete up to a height of around 35 m, building work
continued up to 140 m in the form of a steel construction. Construction work
was carried out in the middle of the plant premises while production operations
continued as usual.
The modern kiln plant stands on 4 massive reinforced concrete columns. Theirrespective cross-sections: 2.80 m x 2.80 m. Due to the tight construction
schedule, they were realised at the same time. For this, PERI and Züblin jointly
developed project-specific climbing formwork on a system basis. The horizontally mounted SB Brace Frame system combined with standardised components taken from the VARIOKIT Engineering Construction Kit formed cantilevered climbing platforms. In combination with the TRIO panel formwork, it wasalso possible to integrate the vault-like widened areas with variable cross-sections in the respective concreting section between a height of 11,50 m and 30 m.
The formwork, reinforcement and concreting operations for all vertical and horizontal components were realised at the same time as the columns due to theextremely short construction schedule. Construction processes at the different
levels required work steps to be coordinated precisely as space was extremely
limited, and secure access had to be guaranteed at all times. Large, connectedmoving units simplified workflows and also reduced crane time requirements
to a minimum.

PERI UP ensured convenient access to the platform levels of the column climbing formwork
thanks to a stairway access assembly that kept
pace with construction progress. Combined with
VARIOKIT system components, the crane-movable PERI UP erection scaffold, which is self-supporting up to 17 m, allowed safe installation of
the beams at a height of almost 30 m.

managed, as the use of time-consuming tube and couplers was eliminated –also for the realisation of guardrails at heights between 192 m and 243. Systemledgers were used here to achieve a force-fitted, stable connections. Circumferential toeboards and the use of PERI UP bridging boards guaranteed closed
decking levels and maximum safety without any tripping hazards.
In spite of large streams of visitors, the work was completed on time. The wellthought-out PERI comprehensive solution proved to be particularly advantageous.
Furthermore, the storage of required materials at the PERI rental park ensured
fast availability and a cost-efficient project solution.
