EIFFEL TOWER
1.
2. The Eiffel Tower was the winning entry in a competition for a 'centerpiece'
for the paris Exposition of 1889. The design by an engineer named
was selected from over three hundred entries for its striking
design and for its economical structure which displayed the French
prowess in metal construction.
3. About
Alexandre Gustave Eiffel was
a French CIVIL ENGINEER
and ARCHITECT. A gradute
of ecole centrale paris, he
made his name with bridges
for the French railway
network, most famously the
garabit viaduct. He is best
known for the world-famous
Eiffel tower, built for the 1889
Universal Exposition in paris,
and his contribution to
building the statue of Liberty
in New york.
4. • The Eiffel Tower cost to build in 1889, an amount
equal to at that time. Today it's cost would equal .
• It is , but this height does not inculde the
on the top; the total height of the is .
• It has a square base that is long on each side.
• There are also inside the Eiffel tower, although visitors can only climb
the first to the first floor. In total the tower weighs ,
. It consist of and put on by
heat.
• The weight of paint used is and the surface to be painted is
.
5. • Since it has been built it has been repainted . Each of these 18 paint jobs
there were only are hired to do the job. of paint
are used on the structure in order to enhance the impression of height, with the
lightest at the top.
• There are and covering the
structure. The paper used to print the visitors’ tickets in one year weighs .
6. • There were 50 architects, engineers, and draftesman that created 5,300 drawings of
Eiffel tower before the construction started.
• Once they had a plan, there were 18,000 pieces built and prepared in Eiffel’s factory
out side of town.
• This pieces were created to the accuracy of 1/10 of millimeter. These pieces were put
together to form new pieces were 5 meters long to be transported to the building site.
• There were 132 workers there to assemble the pieces on site. All the pieces were put
into place and hooked together by thermally assembled rivets.
• There were 4 men needed to assemble a single rivet: one person to heat the rivet up,
another to hold it in place, a third to shape the head, and fourth person to beat the
rivet with a sledge hammer.
7. • Only 1/3 of the 2.5 million rivets were assembled on site. The work on the
foundations took 5 months. The workers only used spades, and the rubble was taken
away by horses and steam locomotives
• The first digging for the foundations began on January 28, 1887 and all construction
was concluded on march 31, 1889.
• When the tower was built, it was only meant to kept for 20 years. People did not like
the Eiffel tower and wanted it taken down because they thought it was an ugly
structure polluting the scenery of the Paris sky.
• After 20 years, the tower became the property of paris again .

9. The Eiffel tower’s base is
composed of four legs. In
these legs are 2 anchor bolts
that are each 26 feet long and 4
inches in diameter. One part of
Eiffel’s plan for the foundation
of the structure was the
placement of a hydraulic jack.
The hydraulic jack was used to
enable the raising or lowing of
the platform to make certain it
was level.
13. • Vertical transports:-
Three lifts (north, east and west pillars) will take you up to the 1st and 2nd floors
(115m). To visit the top floor (276m), visitors needs to change lifts at 2nd floor.
• Number of workers died during construction period is one
• The most interesting fact of the tower is as being one of the most iconic images in the
world, the Eiffel Tower has been the inspiration for the creation of over 30
duplicates and similar towers around the world.
• i.e. Black pool tower, Lasvegas, Tokyo Tower………. & many more.
14. • To use the stairs to the 1st & 2nd floor it is 4.00 Euro
• To go all the way to the top in the elevator it is 12.00 Euro– cheaper if we are in a
group
• The tower opens at 9:30 am, and the stairs close earlier than the elevator– last lift at
11 pm
• To reach the top of the Tower (276m), visitors must take another elevator from the
second floor
15. • The military used the tower as a wireless telegraph transmitter for communication
during battle.
• Today , it is used send radio and television signals to capital city of paris and beyond
the world.
• The Eiffel Tower joined the green energy movement by building two wind turbines
on second level. These wind turbines produce 10,000 kilowatt hours of electricity
each. That is enough energy to sustain the commercial part of the tower on the first
floor.
• The Eiffel Tower weighs 10,000 tons.
• There are 5 billion lights on the lights on the Eiffel tower
