Royal mission



Wirtgen
SP 500
slipform paver at
King Abdulaziz International Airport

King Abdulaziz

International Airport in Jeddah, Saudi Arabia, serves over 15 million
passengers a year
.
The city has the largest port on the Red Sea and is
80
kilometers
from Mecca, Islam’s pilgrimage
destination
.

Named after Abd al
-
Aziz ibn

Saud, the
former king and founding father of Saudi Arabia, the airport was opened in April 1982
.
One of the kingdom’s three international commercial airports, it covers an area of
105
square kilometers with its three runways
.

Wirtgen SP 500 helps
fulfil

r
equirements for takeoff and landing of the
Airbus
A
380

Increasing air traffic volumes and the
higher

air cargo tonnage
prompted the decision
to
expand KAIA Royal Terminal III
.
In the first phase of construction, the apron for
parked aircraft was expanded by
31
,
000

.
In addition, crews have started expanding
the airfield of the
R
oyal
T
erminal, which controls flights for the royal family and guests
of state
.
It is also where the

Airbus A380 is to land and take off in the future on an area
of
34
,000 m²
.

King
Abdullah ibn Abd al
-
Aziz
awarded the contract for both construction
projects to
Bin
ladi
n Group Rush Projects, which
in turn
decided to use the SP 500
.
And
it turned out to be
a good choice,
as
P
roject
M
anager
M.
Ali Mubayedh
explain
s

after
completion of the first phase of construction: “The machine delivered outstanding
paving results and, thanks to consistently high compaction, it extended the service life
of the airfield
.
The slipform paver is totally reliable and the quality of the final product
excellent
.
What’s more, we were able to significantly increase daily performance
,


said
M. Ali Mubayedh
, enumerating the advantages of the
SP 500
.

Paver reliability and
experienced personnel save time and money

The
employees

of
the subcontractor,
Kabbani

Construction Group
,

(comprising one
paving
set

with about 18
workers and employees

who were responsible for cutting
joints and suppl
y
ing dowel bars),
paved
the concrete
with absolute perfection
.
This
outstanding
result was made possible not least by the extensive experience the
subcontractor has
acquired

on comparable projects at other airports, including
Cairo
International Airport in
Egypt
, using machines from Wirtgen
.

In paving the concrete slab
5 meters
wide and
40 centimeters

deep,
the
Wirtgen SP
500
once again proved its great endurance and reliability
.

“During the three
-
month
construction phase for the first
section
, we did not
encounter a
single technical problem



despite the most extreme conditions, at temperatures
which sometimes exceeded
50
degrees Celsius
.
The machine ran smoothly six days a week
.
Without working one
hour overtime, we completed the job ahead of schedule, thereby cutting costs as well
,

added the
P
roject
M
anager
.

Sophisticated technologies: Dowel bar inserter and lateral tie bar inserter

M. Ali Mubayedh
was delighted with the
Wirtgen
technologies
,
including the functional
principle of the dowel bar and lateral tie bar inserters
.
Designe
d for precision and
adaptability, the dowel bar inserter precisely places the 500 millimeter
-
long, plastic
-
coated iron dowels longitudinally into the concrete with the help of electric high
-
frequency vibrators and using a hydraulically controlled vertical
motion
.
The process is
engineered to ensure that during the vibrational insertion of the dowels, they are
oriented

correctly in their final position over the entire working width
.
The

finishing
beam and super smoother also
in use

provided a perfectly level concrete
surface
.
As a
result, the machin
e

operator did
not
need

a second
paving mould

to smooth the
concrete
.

To
guarantee

that the end result was of optimal quality, a surveying team had
checked the surface continuously during

paving and one last time after completion
.

“The
paving
set
and surveying team always work hand
-
in
-
hand at our job sites
.
Quality
is our first
priority

and our team demonstrates this awareness in every way
,


said
Mohammed Nour Almaarawi,
H
ead of
M
aintenance
at

Al
-
Saubai Machineries
,
the
regional
Wirtgen
distributor
.

Second construction phase to be completed by October 2012

After successfully expanding the first
section
, work already is underway on the new
parking area for the
Airbus A380
.
Strict requirements are imposed on the concrete
surface in this case, too, particularly because of the strong forces exerted by the
high
weight of the A380
.
"Here again, good logistics are the pre
re
quisite for successful
concrete paving
,


explains
Mohieddi
ne Sadek,
general manager of
Al
-
Saubai
Machineries.

With years of experience as a
Wirtgen
distributor in
Saudi Arabi
a and after innumerable
major projects, he is very familiar with the regional conditions like those prevailing at
King Abdulaziz Internatio
nal Airport in Jeddah.
He is confident the second phase of
construction will be completed on time by October 2012
:
“Our
SP 500
slipform paver
has been paving concrete metr
e

by metr
e

again since mid
-
May, so we are right on
schedule

Outstanding team
:
The
Kabbani
Construction Group
team specializes in
large
-
scale concrete paving projects,
preferably with machines from the
Wirtgen Group.




SP500_00964_PR


Thanks to its very high c
o
mpressive
strength, the
strip

can withstand
“heavyweights” in the future like the
Airbus A380
,
without forming ruts or
similar
surface irregularities
.







SP500_00962_PR


The finishing beam and super smoother
give the expanded
strip

a perfectly
smooth surface
.




SP500_00961_PR


The side tie bar inserter is available as
optional
equipment feature. Similar to
the dowel bars, the side tie bars are
inserted without interrupting the paving
process
