Dear Readers
Welcome to the latest edition of “diebautechnik”.
Whether in Germany or in distant lands, wherever the team from ThyssenKrupp GfT Bautechnik and its
partners are deployed, the work is properly “tackled”. The broad range of interesting projects you can read
about in this edition of “diebautechnik” shows that, once again, no job was “too hot to handle”.
>> We start on page 4 with the “Champions
League for ports”, the inauguration of
Container Terminal CT 4 in Bremerhaven. This
is a great step forward that will strengthen the
Bremen/Bremerhaven region permanently –
and further evidence that both towns continue
to play in the “Champions League for ports”.
>> The teams in Magdeburg are “delving
deeply” into the low-water problem. The lock
between the Rothenseer Canal and the River
Elbe means that for the first time in its 100year
history, Magdeburg’s inland port is no
longer affected by changing water levels in
the Elbe.
>> “A ticket to Fasanenhof, please!” For
passengers on Stuttgart’s U 6 tram line that
was only a dream up until now. But thanks to
the extension to this line, passengers will in
future be able to travel as far as Fasanenhof.
Read all about this “mega building site” where
again and again new technical and logistics
challenges had to be overcome.
>> By contrast, the work in Hannover Zoo
must have been easy to “bear”! As part of the
Yukon Bay theme world, the sheet pile walls
from ThyssenKrupp GfT Bautechnik ensure
that the salt water tanks remain watertight
– and as a quay wall construction lend the
model seaside town its characteristic charm.
>> In far-away India, ThyssenKrupp GfT
Bautechnik celebrated an exciting première:
for the first time ever the company supplied
an MS-120 HHF with modified connecting
plate for five clamping units for installing
straight web sections 18.5 m long. This was
a demanding project that called for a sensitive
approach both technically and culturally.
>> So, let’s tackle it! But first, we hope you
enjoy this latest edition of “diebautechnik”.

A new class of port
“Champions League for ports” – the festive inauguration of Container
Terminal CT 4 in Bremerhaven
1st class port
Bright outlook for Bremen and Bremerhaven: the new Container Terminal CT 4 allows both towns to “sail” into
the “Champions League for ports”. A notable success which according to Bremen’s mayor, Jens Böhrnsen, will
secure the economic future of the region permanently.
CT 4 guarantees the growth potential
of the region.
>> 12 September 2008, Bremerhaven: the
inauguration of Container Terminal CT 4,
currently the largest port project in Europe.
This EUR 440 million scheme comprises the
1700 m extension to the quay alongside the
River Weser plus the creation of about 100 ha
of storage and operations areas. The project
is one of the largest single investments in the
history of Bremen’s ports. The new container
terminal increases the annual capacity of this
location to at least 7 million TEU (standard
containers). Some 4.9 million TEU were
handled here in 2007. Large areas of CT 4
were already used for container handling and
storage.
“The ports are the heart and soul
of our economy”
In his speech, Bremen’s head of government,
mayor Jens Böhrnsen, emphasized the
significance of the port extension for the local
economy and local job market: “The ports are
the heart and soul of our economy, and hence
the guarantee for the future of our region.”
12 September 2008 was a red-letter day for
Bremen and Bremerhaven: “They belong to
the ‘Champions League for ports’. And today
they have secured a permanent place in that
league.”
4 | germany
>> Böhrnsen pointed out that container
logistics is experiencing stronger growth
than any other branch of industry in Bremen.
“That creates new jobs, which we urgently
need,” he added. “Thanks to CT 4, several
thousand people will find employment in
the coming years – not only in the new port
facilities themselves, but also in many other
areas outside the terminal. For instance, in
haulage and transport companies, and the
many service enterprises associated with the
container business.”
Heavy, anchored sheet piling
forms a key structural element
The construction of the new quay employs
the principle of an anchored wall in front of
a load-relieving platform. The designers were
able to call upon good experience gained with
the design and construction of earlier projects
for the riverside quay.
A heavyweight sheet pile wall anchored
by raking piles forms the main structural
element of the quay on the water side. After
the anchorages are in place, the wall can be
backfilled with sand. Behind the sheet pile wall
there is a slab that relieves the loads on the
wall, with a short sheet pile wall at the landside
end of the slab.
Some 3600 steel piles were impact-driven and
vibrated into the ground for the new quay. A
total of 743 bearing piles – each 40 m in length
and weighing 25 tonnes – support the quay;
these are linked together with intermediate
sheet piles and tied back with raking piles.
In total, the construction of the sheet pile walls
around the terminal consumed about 40 000
tonnes of steel!
ThyssenKrupp GfT Bautechnik was on hand
to provide optimum supervision of the work
on site and immediate assistance in the
case of problems, which could then always
be solved without unnecessary discussions
or delays. However, the excellent quality
and outstanding condition of the plant used
rendered intervention superfluous.
“We know how to build ports in
Bremen”
>> The Senator for Industry and Ports, Ralf
Nagel, highlighted the professional planning
and rapid realisation of the construction
measures, which meant that CT 4 could
be brought online 14 months earlier than
originally envisaged! The rapid completion
also resulted in a saving of tens of millions of
euros over the original cost estimate for CT 4.
Nagel summed it up: “We know how to build
ports in Bremen and the port managers at
bremenports are our guarantee of this.”
The completion of CT 4 and the building of the
Kaiser Lock mean that Bremerhaven is well
prepared for the growth potential of the coming
years. “What we now have to ensure is
optimum exploitation of the potential for economic
strength and employment at the ports.
In this respect, we need to improve the inland
access to the ports. And that means further
bold decisions need to be taken in the future,”
according to Nagel.Die „

concept represents a harmonisation of the previous
port management with the structure of the companies
operating here – and hence a considerable improvement
in the productivity and flexibility of the port as a whole.

Longing for the long lake...
Böblingen Airfield – an urban district with its own character takes
shape in Sindelfingen
Workers enjoying the relaxing view across the lake in their lunch breaks, couples strolling unhurriedly along the
airfield lake promenade... It will take a while before all this becomes reality, but the first step towards realising
the lake landscape has already been taken.
>> It was on 11 July 2008 that the mayors
of Böblingen and Sindelfingen, Alexander
Vogelsang and Dr. Bernd Vöhringer
respectively, pressed the button to start the
first driving operation for the building works
around the “Long Lake”. The planned lakeside
promenade will dominate the atmosphere
of the entire former airfield – and lend it its
very own character. The local residents will
also be pleased – the lake will provide them
with an attractive recreational area on their
doorsteps.
“For the people who work in the offices
and industries on the airfield, the banks will
provide an ideal location for relaxing breaks,”
according to Alexander Vogelgsang, chairman
of the company responsible for developing
the area. He and Dr. Bernd Vöhringer from
Sindelfingen – supervised by engineers
– together pressed the button that started
the vibratory hammer for the first pile-driving
operations on the site.
Hard work
>> This started the vibratory driving of the
first of 1800 tonnes of LARSSEN 605 double
bearing piles into the ground. Owing to the
Böblingen Airfield
poor subsoil conditions, the soil had to be
loosened by drilling on both sides of the
driving axis. The sheet piling sections, up
to 8 m long, were driven up to 7 m into the
ground – the final few metres being achieved
with a D19/52 diesel hammer. The sheet piling
forms two 860 m long, parallel sheet pile walls
that are joined by round steel tie rods to create
a cofferdam.
Sealing by the metre
The sheet pile wall on the water side of the
cofferdam had to be sealed with HOESCH
interlock seals. This involved the Hartmann
company injecting approx. 6400 m of seal
material into the interlocks of the sheet pile
wall at their factory in Dortmund.
From the northern bank...
>> Once the northern bank has been
stabilised, the construction of the lakeside
promenade can begin. Up to 10 m wide, it will
pass by offices, showrooms, restaurants and
apartments. In order that local citizens can get
right down to the water’s edge, a total of 80 m
of the northern bank will be terraced. At the
north-east corner of the lake the promenade
continues as a footpath and cycle track leading
to the fairground. From the eastern bank there
is a view across the entire airfield – a site
seemingly destined to become the home of a
small restaurant.
...to the green heart
The southern bank of the lake provides a
distinct contrast to the hard, urban northern
bank. The development plan provides for
natural, “soft” landscaping leading to the
green heart and the residential areas. A belt
of reeds will block access to the lake for
the most part, but there will be platforms
providing access to the water. To prevent the
reeds spreading into the lake and reducing the
area of clear water, a concrete retaining wall
will be built to separate the lake and the reeds.
Floating reed banks in the lake will improve
the appearance of this wall.
Looking across the lake to the
future...
>> The cost of the bank landscaping will amount
to appox. EUR 1.5 million. A total budget of
approx. EUR 14 million has been allowed for.
Besides its aesthetic appeal, it also functions
as a rainwater retention basin and together
with five rainwater treatment plants fulfils an
ecological harmonisation function. Once the
“Long Lake” is completed in 2010, together
with the surrounding planting and open areas
it will serve as a leisure and recreational area
for the residents and workers on this former
airfield.

A welcome from “Tall Anna”...
Heligoland in the North Sea: ThyssenKrupp GfT Bautechnik and its partners
repair coastal protection around the “Kringel”
“Tall Anna” with her protective wall extending down into the sea. This freestanding stack of
red variegated sandstone is located on the extreme north-west tip of the island.
Heligoland
The striking red rock contrasts with the blue-and-white sky over the sea... At 47 m high and weighing in at about
25 000 tonnes, “Tall Anna” is Heligoland’s “heavyweight” landmark. Here, where the sheet pile walls themselves
are steeped in history, the teams from Hamburg-based contractor H.C. Hagemann and ThyssenKrupp GfT
Bautechnik faced a very special type of challenge.
>> The historical background: On 18 April 1947
the British Royal Navy detonated thousands of
tonnes of explosives in what turned out to be
the largest non-nuclear explosion in history in
order to destroy the military bunker facilities
on the island. The mountains of debris around
the southern tip of the island created the
“Kringel”, which was protected by a sheet pile
wall and corresponding revetments in 1964-
65. This wall had become badly corroded and
in front of the walls erosion had caused the
tetrapods to subside; the revetment paving
was missing in some places.
The current project: The first stage of the work
was to move the 1500 tetrapods in front of
the existing protective sheet pile wall around
the “Kringel” in order to create space for the
new site road for carrying out the new works.
The tetrapods dating from the 1960s weigh
about 6 tonnes each. They were moved
forwards one by one and by the end of the
project will have been joined by a further 1750
new tetrapods to form a higher protective
wall to dissipate the power of the incoming
waves. The space cleared for driving was still
littered with concrete debris which also had
to be cleared away down to a depth of about
1 m. The remaining backfilling of variegated
sandstone rubble, covering the undisturbed
variegated sandstone bedrock, was about
2 m deep.
Distinctive solution – bearing
piles driven into the ground
>> In order to provide permanent coastal
protection, a combined steel pile wall consisting
of PSp 400 and PZi 675/12 sections was driven
in front of the existing sheet pile wall structure.
This was a special solution proposed by the
contractor H.C. Hagemann GmbH & Co.
KG, who was assisted by ThyssenKrupp GfT
Bautechnik.
sandstone, the intermediate pile sections
about 0.30 m; the bearing piles are 8.10 m
long, the intermediate piles approx. 5.50 m.
Owing to the section chosen and the specially
fabricated base detail, it was possible to
drive the bearing piles into position. Cranesupported
Hydrohammer S70 units were
used for the driving work. Up to 350 blows
per 100 mm were necessary to drive the
bearing piles to their full depth.
>> After the driving, the space between the
old and new walls was filled with concrete
(grade C30/37) up to the underside of the
new capping beam. The raking piles of the
old construction were still in a sufficiently
good structural condition to provide about
50% of the anchorage for the new wall – the
other 50% is provided by new round steel tie
rods and anchor walls in the ground. Both
forms of anchorage
are connected to the
reinforced concrete
capping beam.
Transport by
sea – from bulk
goods to the
smallest bolts
The fabrication of
the PSp 400 bearing
piles with their spe-
cial base detail was

Construction time:
April 2008 to June 2009
The problem: All materials and machines
– from bulk goods to the smallest bolts – have
to be sent by sea well in advance.
>> Owing to the exposed position of the
coastal protection on the south-west side
of the island, the “Kringel” is permanently
subjected to the power of the incoming waves.
This is primarily the situation with south-west
and north-west winds, with a 60% probability
of such winds occurring in the period from
October to March. Therefore, no construction
work can be carried out during those months
because the downtimes would be immense,
the risk of storm damage too high.

Delving deeply...
>> Non-stop right up to the port – even with
a low water level. Thanks to the planned
low-water lock in the southern section of the
Rothenseer Canal, from 2010 onwards all
ships will be able to negotiate this section all
year round with a full load.
>> After Duisburg, Magdeburg is Europe’s
second-largest internal port. Currently, the
water level in the port matches that of the
River Elbe.
The problem: With a low water level in the
Elbe, fully laden ships in the Mittelland and
Elbe-Havel Canals cannot negotiate the
Magdeburg-Rothensee Lock to reach the port
itself.
The idea: Constructing a lock at the exit from
the Rothenseer Canal, where it joins the Elbe,
will make Magdeburg’s port independent of
the fluctuating water levels in the river – for
the first time in the port’s 100-year history.
The remote-controlled lock is only intended to
operate in the case of a low water level.
Non-stop to the port – even with
a low water level.
>> The lock facility consists of the lock itself
(currently still under construction), lock
chamber (190 x 25 m), cofferdam, upper/lower
lock gates and pumping station (consortium:
Mölders, Hannover/August Prien, Hamburg)
plus the outer basin (essentially finished)
and the sheet pile wall along the banks of the
Elbe (consortium: Johann Bunte, Papenburg/
HydroWacht, Gerwisch).
>> All the above works are being carried out
in sheet piling. In particular, the sheet pile
walls to the lock chamber are sealed with
the factory-fitted HOESCH interlock seals to
ensure they remain permanently watertight,
even in the case of draining the lock chamber.
In addition, the armouring as well as fittings
such as armoured ladders and bollards were
factory-fitted by our partner ASF Anton Schmoll
5800 tonnes of LARSSEN 23 sections were installed in this project.

GmbH for the two entry sections – and driven
together with the sheet pile wall.
Once the lock is completed in 2010, it will be
“out of action” for an average of six months
every year. Ships can then travel unhindered
from the Mittelland and Elbe-Havel Canals
through the ports and into the River Elbe
– provided there is sufficient water in the Elbe.
Low-water lock
in Magdeburg
Low-water lock in Magdeburg: ThyssenKrupp GfT Bautechnik supplied a
stable LARSSEN 23 sheet pile wall and all the necessary port fittings
Only in the case of a low water level will the
lock gates be closed. Ships that wish to pass
from the canals to the Elbe can then for the
first time reach the Magdeburg port in order to
be lightened before passing through the lowwater
lock into the river. At the moment the
lightening work has to be carried out in other
ports.
Difficult driving conditions
The client opted for a sheet pile wall with
LARSSEN 23 sections and a system width of
500 mm – on the one hand to prevent ships
being caught in the troughs, and on the other,
an extremely stable sheet pile wall system is
necessary so that the piles can be driven to the
depths required by the calculations. Around
the Magdeburg port facilities the readily
driveable sand and gravels cover a stratum
of septarian clay, into which the sheet piles
had to be driven to a depth of 6 m. This clay
causes very difficult driving conditions and a
stable sheet pile wall system is necessary in
order to transfer the energy of the large IHC
S 70 piling hammers safely and reliably into
the subsoil.
Looking north: the low-water lock in Magdeburg.
>> ThyssenKrupp GfT Bautechnik supplied
a total quantity of 5800 tonnes of sheet pile
wall in lengths of up to 21.50 m plus a total
of 1200 tonnes of HEB 240 beams for the
raking pile anchorages in lot 4. At the moment
ThyssenKrupp GfT Bautechnik is supplying
fittings such as round steel tie rods, walings,
beams, bollards, edge protectors and marker
piles for lot 5.
Difficult conditions – winter high
water in the Elbe
Driving the raking piles in lot 4 proved to be
especially difficult from the timing viewpoint
because the work coincided with the period of
high-water levels in the river in the winter of
2008. The openings in the sheet pile wall for
driving the piles were up to 3 m below water
level for several months, which ruled out
installation.

A ticket to Fasanenhof, please!
Prestigious project in Stuttgart: extension to Stuttgart’s U 6 tram line
Stuttgart
Changing trams will soon be a thing of the past for all those who want to travel to Fasanenhof on the U 6 line.
Thanks to an extension to the line, the U 6 branches away northwards from the motorway, directly towards
Fasanenhof. The first 800 m of the line are above ground, then a 250 m long ramp takes the trams underground,
passing safely beneath Fasanenhofstrasse at Bonhoeff Church.
The total length of the planned extension is
2.75 km.

>> The building site: The project involves a
number of challenges. Twin-channel sections
had to be supplied for the soldier pile walls,
not only in large quantities, but also in diverse
lengths and sizes. The different phases of
the work meant that the team was regularly
confronted with new in situ conditions. Besides

the elaborate logistics, it was also important
to consider the structural aspects particular
to this project. For example, in this project
30 mm thick baseplates were used instead of
the 10 mm normally employed.
The route: Tram line U 6 is being extended
as far as Fasanenhof. The total length of
this section is 2.75 km, with 650 m of the
line in a tunnel built using the cut-and-cover
technique. Soldier pile walls will be used here
to secure the sides of this excavation; 370 m
of the tunnel will be bored below ground.
Deployed by the metre
The use of twin-channel soldier piles of
different lengths is necessary for the following
reason: At the start of the cutting for the
tunnel, the excavation is approx. 2.50 m
deep. By the time the line reaches the tunnel
portal, the excavation is up to 14 m deep In
addition, in some sections of the work the
soldier piles on one side are a different length
to those on the other – even though the base
of the excavation is at the same level on both
sides. Different structural conditions behind
the wall to the excavation are the reason for
this. For example, nearby buildings (including
a kindergarten and housing) lead us to expect
a higher active earth pressure. In these cases
an extra line of anchors is more likely to be
necessary than on the opposite side in order
to minimise the deformation of the excavation
shoring.
>> No sooner said than done – anchors were
installed: Some 1450 anchors with a total
length of about 18 000 m were bored after
completing the excavation work. The number
of anchors increased gradually from one at the
beginning of the cutting to a maximum of five
near the tunnel portal. The anchorage works
commenced around the middle of July 2008
and were not completed until the winter.

30 mm thick baseplates
The structural calculations called for 30 mm
thick baseplates on this project (instead of
the 10 mm usually necessary). Furthermore,
vertical loads of up to 70 tonnes have to be
carried via end bearing and skin friction over
the embedment length of the soldier piles, the
bases of which are encased in concrete. Soldier
pile walls were chosen because of the ground
conditions encountered (hard and soft rocks,
mudstone, marlstone and Stuttgart’s principal
sandstone beds). Installing sheet pile walls
without drilling would have been impossible.
Furthermore, for economic reasons this
method was not even considered.
>> Special challenge: The soil strata mentioned
above, which can only be drilled with Widiatipped
tools. And as if that wasn’t enough: the
cut-and-cover section of the tunnel is located
in the middle of a residential district, where
special attention has to be paid to noise and
dust problems. As the outer wall of the tunnel
is cast directly against the excavation shoring,
the normal DIN construction tolerances were
reduced to a minimum.
>> And another complication: In the eastern
open excavation all the soldier piles had to be
installed underneath existing overhead power
cables.
14 | germany
Excavation shoring remains in
the ground
The twin-channel soldier piles were used
within reach of the two cranes. The cranes
were set up directly on the soldier piles on
each side of the portal wall. The drilling works
for the soldier piles were carried out in the
period March–August 2008, beginning with
one machine.
The amount of drilling totalled approx.
8500 m, and 750 twin-channels with a total
weight of 1000 tonnes were installed. All the
channels remain in the ground. On the one
hand because the planned line of the route
leaves no space for extraction plant alongside
the excavation shoring. On the other, the
embedment lengths of the channels are
encased in concrete below the base of the
excavation, and the infill panels between the
channels are finished with sprayed concrete
up to a depth of 1.50 m below ground level.
From the client’s viewpoint this is apparently
the most economic solution for realising this
project, even though a huge quantity of steel
remains buried in the ground.
Some 650 m of tunnel are being built using the
cut-and-cover method.
Twin-channel soldier piles up to 18 m long
were transported by road from Peine to Stuttgart.

Happy polar bears
A project at Hanover Zoo:
Yukon Bay – a sheet pile wall for the polar bears
Wolves, caribou, polar bears... Alaska can now be found in the heart of Hannover. Currently taking shape in
the city’s zoo is a fascinating theme world – Yukon Bay. The sheet pile walls supplied by ThyssenKrupp GfT
Bautechnik ensure watertight salt water tanks and lend the quay wall construction of the model seaside town its
characteristic charm.
>> The special feature of this project: A zoo
structure like this calls for a sheet piling
structure with an ingenious geometry and
tightly interlocked sections.
Due for completion in April 2010, artificial
mountains, a river, a seaside town with port
basin and much, much more are being built
on an area of 22 000 m 2 at a cost of EUR 31.6
million. A concept with diverse sheet piling
structures was developed by lead architect
Dan Pearlman and consulting engineers grbv
in order to master the water and landscaping
problems.
The ingenious geometries mean that the
contractors are faced with a huge challenge.
Made-to-measure work: some 3000 m
of cuts and 5000 m of welded seams
were necessary.
Fixed delivery dates – no
problem for ThyssenKrupp GfT
Bautechnik
>> Even before the first construction measures
for Yukon Bay began in early 2008, the
delivery dates for the sheet piles had been
fixed. Owing to the tight schedule, the client
decided to issue a tender for the sheet piling
– separately from the tender for the driving
works. This guaranteed that construction was
not delayed by unexpectedly long delivery
times for the sheet piles. ThyssenKrupp
GfT Bautechnik submitted a bid and was
subsequently appointed by Zoo Hannover
GmbH to supply approx. 730 tonnes of
sheet piles. Together with supplier HSP and
sealing specialist Hartmann, ThyssenKrupp
GfT Bautechnik was able to supply all the
steel components on time. Hannover-based
haulage contractor B&M was subsequently
appointed by ThyssenKrupp GfT Bautechnik
to carry out the deliveries and the correct
storage of the sheet piles on the building site.
Hannover Zoo
Watertightness in both directions
– an unusual request
The problem: The high water table at this site
made it necessary to carry out dewatering of
the excavation first. Apart from that, it had to
be guaranteed that, after completion, no salt
water could escape from the tank into the
surrounding groundwater. It was therefore
decided to use the high-quality HOESCH
plastic sealing system, which achieves
maximum watertightness and offers longterm
resistance to diverse environmental
influences. The Dortmund-based Hartmann
company fitted interlock seals to about 500
tonnes of sheet pile walls.
The construction of the theme world called
for accurate sheet piling operations.
A driving plan with nooks and
crannies – centimetre accuracy
required at every corner
>> A driving plan of a very special kind was
presented to the contractor, Gebr. Echterhoff
from Westerkappeln: some 3000 m of cuts
and 5000 m of welded seams were necessary.
Almost every corner was constructed with
a make-up pile fabricated in situ following
on-site measurements accurate to within
centimetres. It was the architects who called
for this exact approach; the given geometries
of the tanks and site typography had to be
maintained exactly in order to achieve the
desired overall impression.
>> A MÜLLER MS-16 HFV vibrator with double
clamping units attached to a Liebherr LRB
125 leader was used for the driving work.
ISCHEBECK Titan grouted anchors were used
to tie back the sheet pile walls and provide uplift
protection for the underwater concrete bases.
The innovative Titan self-drilling system saved
considerable time on site. And time is money,
as they say, if the polar bears are to move into
their new home on time in April 2010!
To help “bear” the costs: a tailored driving plan
• Some 3000 m of cuts and 5000 m of welded seams were required
• Workmanship accurate to within centimetres for the make-up
piles fabricated on site
• The demands of the architects: tank geometries and site topography
had to be maintained exactly
• The innovative ISCHEBECK self-drilling micropile system saved
considerable time on site

Out in the cold...
The building of the Hodariyat Bridge in Abu Dhabi – ThyssenKrupp scores extra
points thanks to extremely short delivery times for the steel pile casings
Like a mirage, once finished the bridge will appear to “float” over the
Khor al Bateen in Abu Dhabi. The Hodariyat Bridge will link the urban
district of Al Bateen on the main island with the island of Hodariyat.
This is an ambitious project, which ThyssenKrupp GfT Bautechnik was
able to win thanks to its fast delivery times – leaving the competition
“out in the cold”.
18 | worldwide
Abu Dhabi
The Hodariyat Bridge links Al Bateen on the main
island with the island of Hodariyat.
>> The plan: The extension to Al Saada Street
West includes a bridge 1400 m long over the
Khor al Bateen – supported on 18 secondary
and two main piers. The clear span of about
200 m between the two main piers is located
in the middle of this waterway almost 1 km
wide.
The client for the Hodariyat Bridge is the
Tourism Development & Investment Company
in Abu Dhabi. Züblin International GmbH was
appointed as the contractor for the bridge. The
cost of this considerable construction project
is equivalent to about EUR 160 million.
Shortest distance
>> Working closely together with our
cooperation partner ThyssenKrupp MANNEX,
ThyssenKrupp GfT Bautechnik supplied 369
steel tubes with a total length exceeding
6100 m. These tubes serve as formwork for
the concrete piles beneath the bridge piers.
They will be driven into the seabed from
pontoons and subsequently filled with
concrete.
Besides relevant experience of such work,
it was primarily the short delivery time that
won the contract for ThyssenKrupp GfT
Bautechnik.
Together with ThyssenKrupp MANNEX, ThyssenKrupp GfT Bautechnik supplied 369
steel tubes with a total length of 6100 m.
And indeed, ThyssenKrupp GfT Bautechnik
was even able to build on this “advantage”
during the course of the project. Instead of
sending the tubes by sea from the rolling mill
in Qatar, they were delivered by trucks directly
to the building site. This solution proved very
popular with the client, who saved the cost of
the intermediate transport from the port in Abu
Dhabi to the building site, plus troublesome
and time-consuming customs formalities.

On trial down under
Refurbishment of the Cronulla sea dyke in New South Wales, Australia
20 | worldwide
Cronulla
Deep blue skies and crystal clear water, surrounded by a gorgeous beach. But where others are surfing or
building sandcastles, the SFL/Piletech team is constructing a sea dyke. The project itself is anything but a “stroll
along the beach”. Because storms, floods and the constant migration of the sand have really put the team’s
abilities to the test.
>> The contract for a considerable section of
the Cronulla sea dyke refurbishment project
was awarded to Piletech, which since a
corporate merger trades under the name
of SFL/Piletech. The merger increased the
competence of the driving experts, who in the
meantime are among the largest and most
important specialists in Australia. Piletech
is the general contractor for the project and
supplies the construction timetable.
But the project involves a number of significant
risks. Owing to the local circumstances, the
problems began with the preparation of the
building site. Besides preventing access by
the public, it was primarily environmental
issues such as storms, floods and the
constant migration of the sand that turned the
refurbishment of the sea dyke into a serious
challenge.
Lightweight sections are mainly used for dyke refurbishment
or trench shoring in urban situations. The interlock of the
lightweight section serves as a reliable hook.

Moment of resistance (Wy cm³/m wall): 276
Self-weight (kg/m² wall): 45,2

Section width (mm): 700
Height of wall (mm): 146
Back & web thickness (mm): 4,0
>> In order to realise the dyke refurbishment,
several steps had to be taken at once.
After removing the existing, ruined gabion
construction, some 700 bored piles had to be
installed. The aim of the project is to refurbish
the existing sea dyke, which is to have a new
wall with anchor heads at its base.
The KL 3/4 section – also perfect for use in sand.

“Namasté!”*
ThyssenKrupp GfT Bautechnik and ESSAR Construction Ltd: first-ever use
of five clamping units for installing straight web sections in India
Honeycomb-like cells in India.
The local teams celebrated an exciting première in India: for the first time in the history of ThyssenKrupp GfT
Bautechnik, a contract was awarded for supplying a MÜLLER MS-120 HHF vibrator. The outcome was a technically
challenging project – and the first successful step into the Indian market. Or in the words of a well-known Hindu
greeting: “Namasté!”* – welcome to the Indian market!
* “Namasté” means “I greet and honour you.”
22 | worldwide
India
>> The project: Following intensive discussions,
the contract to supply an MS-120 HHF
to India was awarded to ESSAR Construction
Ltd. in the spring of this year. The plan was to
install 45 cells, for which straight web sections
and plant had to be provided. Thanks to its offer
of a special technical solution for the plant
required, ThyssenKrupp GfT Bautechnik was
awarded the contract.
Getting to grips with the problem
– first-ever use of five clamping
units
ThyssenKrupp GfT Bautechnik sold the
customer an MS-120 HHF with modified
connecting plate for five clamping units for
installing 18.5 m long straight web sections.
As this was the very first two-in-one machine
that had been supplied to India, the engineers
from Alsfeld carried out the installation and
the training of the operatives on site.
>> The cells are being built on a man-made
embankment so that they will be able to
carry the heavy loads of the structure in the
final condition. Owing to the additional loads
on the subsoil due to transport and similar
actions, the force spreads out horizontally
in the ground, which means that the load
is distributed vertically on the sections. It is
planned to build more than 70 cells. This
means that for each cell 45 sections have
to be installed straight and a further approx.
35 sections on a radius of approx. 24 m. The
sections are approx. 18.5 m long.
“Good vibrations” – difficult
driving of straight web sections
Up until now cells with straight web sections
had only been installed for a hydroelectric
power station in Korea. Straight web sections
of this length are being used for the first time
in India.
The difficulty: Generally, straight web sections
are not easy to drive because their low stiffness
in one direction means they are vulnerable to
buckling. The idea behind driving several (five)
sections at once is to reduce this weakness,
and vibratory driving will improve progress.
>> As the MS-120 HHF, like all two-in-one
systems, has an adjustable eccentric moment,
amplitude and frequency for a constant
centrifugal force, the unit can be adjusted to
suit different subsoil conditions.
A high frequency is used for sandy soils in
order to minimise the displacement. A low
frequency and a high eccentric moment are
used for cohesive soils in order to reinforce
the friction effect between pile and soil.
The advantage: In this project there is the
chance to vary the frequency and amplitude
for a constant centrifugal force to suit the
subsoil conditions. The MS-120 HHF cranesupported
vibrator is the second machine to
be exported to India – the first one arrived in
that country in the early 1980s.
The bottom line: This represents the first,
successful step into the Indian market.

Typical market scene in India.
A close look at the Indian
market
>> The construction sector is becoming more
and more significant in the Indian market.
Accordingly, the volume of investment over the
next five years will reach about US$ 656 billion.
An examination of the individual infrastructure
sectors shows that some have already
developed or are undergoing development.
Consequently, a lower volume of investment
can be assumed for these individual areas.
>> The quality and quantity of seaports and
airports are obviously adequate – an extremely
important aspect for trade. Steel products and
machinery can exploit this advantage in the
existing infrastructure (e.g. for deliveries).
Of course, the existing infrastructure is not
comparable to that of Germany, but it is
adequate for transporting materials and plant
to and from local building sites.
Résumé: On the whole, the expansion of the
larger sectors shown in the diagram below
adds up to interesting potential for lucrative
business.
24 | worldwide
Looking back and looking forward: The
competitive situation in India is characterised
by the dominance of the large Indian
corporations. Up until now, ThyssenKrupp GfT
Bautechnik has fostered contacts with Larsen
& Toubro (2006), ESSAR (2008) and Gammon
(2008). There is a large, fast-growing number
of top players in the construction sector. And
there is “ample scope” for companies to
position themselves as building technology
enterprises – and to secure market shares in
this rapidly developing country.
>> The attractiveness of the existing market
should grow successfully over the coming
years, taking into account the framework
conditions.
When in Rome...
The interesting thing about this market: India
represents a conglomerate of the most diverse
cultures. Owing to the number of religions and
public holidays, companies are recommended
to take these into account when planning their
business meetings.
Even the choice of a restaurant demands
special care because depending on beliefs,
caste and social ranking, certain forms of
behaviour play a significant role. But despite
these cultural idiosyncrasies, ThyssenKrupp
GfT Bautechnik has taken an important step
into the Indian market.

of products and the core skills of the company.
ConBuild Vietnam, a relatively large trade fair
for the market in that country, saw the team
from ThyssenKrupp GfT Bautechnik presenting
the MÜLLER MS-20 HFV (see p. 26).
ConBuild Vietnam, Hanoi, 8–12
September 2008
>> Vibration technology in particular is at a
very early stage of development in Vietnam,
which means that the potential for using
this technology has by no means been fully
exhausted. Important projects for Vietnam are,
above all, securing energy supplies, improving
the infrastructure, expanding industrial zones
and providing housing.
The first vibratory hammers have already been
sold. Driving and extracting work as part of
the expansion measures at a steel fabricator
in Hai Phong and trench shoring works for a
housing project in Hanoi have already been
carried out.
ThyssenKrupp GfT Bautechnik sees great
potential in this market and is pleased to
be able to participate in the development of
the country’s infrastructure, ports and cities
through the use of our machinery. Therefore,
the aim is to expand our sales options through
specific activities in order to secure market
shares with the help of German engineering
skills in this attractive part of the world.
Fematech, Buenos Aires,

The MÜLLER MS-50 HHF vibrator was
exhibited at Fematech in Buenos Aires,
Argentina, together with Cimtronic. Within
the scope of a series of presentations at this
event, ThyssenKrupp GfT Bautechnik was able
to demonstrate its product portfolio in a twohour
presentation given by Mr Rautenberg.
Bauma, Shanghai, China, 23–28

Our presence at this event closed the trade fair
calendar for 2008. Like so often in the past,
synergies were exploited here in the shape
of a joint stand for ThyssenKrupp Steel and
ThyssenKrupp GfT Bautechnik. ThyssenKrupp
Steel is known for its high-strength special
steels with specific properties.
Together into the future: the team from ThyssenKrupp GfT
Bautechnik and their colleagues from Vietnam at ConBuild

ThyssenKrupp GfT Bautechnik exhibited an
HB 30 A hammer drill. With more than 25 000
visitors every day, this fair, the largest in Asia,
speaks for itself. The status of development
in Chinese machinery, which has a high

“Vibration alarm!”
ThyssenKrupp GfT Tiefbautechnik expands its product portfolio: new vibrators
and computer-controlled data acquisition during driving and extracting
Fast and flexible! These are the demands placed on the machinery by the Tiefbautechnik team on every modern
building site. And not without reason! Owing to the constantly changing on-site conditions, piles are becoming
heavier, longer and larger, meaning that the technology has to be constantly adapted to the new requirements.
>> As a leading producer of hydraulic MÜLLER
vibrators, ThyssenKrupp GfT Tiefbautechnik,
Alsfeld, does its utmost to fulfil these criteria.
A powerful, compact vibrator has therefore
been added to the company’s range of

• Routing the hose outside the spring yoke
simplifies maintenance
• The modified spring yoke means that
setting down the unit does not subject the
suspension ropes to severe stresses
• Low weight for a higher performance
• Optimised output for the HFV series
• Optimum exploitation of this vibrator’s
performance is ensured when used
together with the MS-A 420

Like with all MÜLLER vibrators, the power
of the unit is not limited by the power pack;
instead, the oil flow and oil pressure are
always adequate for optimum exploitation of
the vibrator properties.
Computer-controlled acquisition of
data during driving and extracting.
MS-EDGR MÜLLER system –
Electronic Data Geological
Report
Recording the installation parameters – such
as frequency, pressure, depth – when driving
piles with vibratory hammers has become
extremely important in specialised civil
engineering. This data acquisition provides a
reliable, fast and simple method of revealing
unforeseeable deviations from the design
parameters, e.g. obstructions and changes in
the anticipated subsoil conditions.
How does the system work?
The MS-EDGR system is integrated into the
power pack control unit. Using a computer,
the user can retrieve the data via a serial port
(cable), the GSM network, ISDN network or
GPRS Internet.
Measuring box with signal lamps.
Owing to clients’ varying needs and
differences in the output formats, the data can
be transmitted in a variety of formats.
The advantages of MS-EDGR
• Optimum system compatibility – electronic
data acquisition and vibration unit direct
from the manufacturer
• No loss of data
• Precise parameter acquisition –
also beyond the standard values
• Simplified data log output
• Remote diagnosis
• Online monitoring of operating
parameters
• Automatic vibrator control for complying
with DIN 4150 values
• Possibility of logging parameters exceeding
the standard values
Based on the logging (measurement) of the
vibration propagation, the MÜLLER power
pack control can exert an automatic influence
on the frequency and amplitude of the MÜLLER
vibrators of the HFV series according to DIN
4150 and specific site parameters, and hence
avoid the critical vibration of neighbouring
structures.
For those vibrators, e.g. excavator-mounted
units, that do not require a MÜLLER power
pack, compliance with given limit values
is made possible by visual signals. This
is achieved with the help of an external
measuring box with signal lamps.
