Architectural Construction Of The Eiffel Tower, France

The Eiffel Tower is an iron tower located next to the River Seine in Paris. It is one of the most recognizable and popular structures in the world. in fact this is one of the most spectacular landmarks in Paris. Named after its designer, engineer Gustave Eiffel, the Eiffel Tower is the tallest building in Paris. Its construction in 1889.

Built for the universal exhibition of 1889, to mark the centenary of the French revolution, the Officiel Journal launched a major competition to erect an iron tower on Champ-de-Mars. The tower will have a square base, 125 meters on each side and 300 meters. "The proposed project by entrepreneur Gustave Eiffel, engineers Maurice Koechlin and Emile Nouguier and architect Stephen Sauvestre were selected from a total of 107 candidates.

The project plan began in 1884. Due to obstacles that were public demonstrations and intellectuals, the tower construction began in 1887 and was completed 26 months later in 1889. It was planned that this tower would be demolished after the 1900 World Expo weekend. However, successful trials of transmission the radio controlled by the French Armed Forces before the restoration day finally saved the Eiffel Tower.


Fifty engineers and designers produced 5,300 images, and more than 100 workers produced more than 18,000 different tower sections in the workshop. 132 field workers gathered directly in the construction area.

Work on the foundation of the tower began on January 26, 1887 and spent five months, with the workers using spades only. The ruins were taken away by carts drawn by horses and steam locomotives. The deepest foundation lay only 15 meters underground. The legs of the towers are set in each of the base trenches (four foundations in stone, supported by four pillars, known as the frame truss).

First floor assembly. The difficulty of determining floor assembly lies at the starting point at the bottom of the truss frame. The material must be positioned at an angled angle so that it will meet the horizontal beam on the first floor. To achieve this, engineers used a hydraulic jack to move each "foot" and established a scaffolding system we know today, above a number of sandboxes emptied to adjust the slope of the truss frame.

The second floor is assembled with a crane that takes the same path as the elevator. All parts are built in Eiffel workshop in Levallois. The tower was installed somewhat like a gigantic Meccano® (stacked toy frame) with tremendous precision, which was a major innovation at the time. From the second floor to the third floor, the carpenters worked extraordinarily and there was not a single fatal accident during the construction period.

The monument was inaugurated on March 31, 1889. On that day, Gustave Eiffel climbed 1,710 stairs The Tower planted a French flag at its peak. He was followed by members of the Paris Council, including Emile Chautemps, President of the Paris City Council. The Eiffel Tower was the tallest building in the world until 1929, when the Chrysler Building in New York was built with a 319-meter peak.

Construction Stage

Materials used: Iron steel is linked in the form of a cross from 18,038 seeds reinforced with 2,500,000 nails. The framework of Gustave Eiffel's work is windproof and although the material is from iron, the weight of the tower is only 7,300 tons.

Construction Data

  • Project Leader: Mr. Gustave Eiffel is assisted by, among others, engineers Maurice Koechlin and Emile Nouguier and Stephen Sauvestre as architects.
