This is my tenth skyscraper based off of Spencer Rezkalla's original design, and my eleventh overall. Completed in 1889, the Eiffel Tower stands on Paris' Champ de Mars and was built as an entrance arch to the 1889 World's Fair. Consisting of 18,038 different pieces and two and a half million rivets, La Dame de fer (the iron lady) was put put together by 300 workers over a two-year period. The tower's namesake, Gustave Eiffel, was the project's engineer, assissted by engineers Émile Nouguier and Maurice Koechlin and architect Stephen Sauvestre. Originally, Eiffel's permit for the tower required that it be dismantled after 20 years, which would have been in 1909. However, La Tour Eiffel proved invaluable for communication purposes and was allowed to remain after the permit's expiry.
This model is my third international skyscraper and my first attempt at a skyscraper built completely out of flex tubes. Working on this model was a fun process because of the discovering-while-building aspect of it. In other words, there was no specific plan for exactly what number of pieces this model would contain or how the pieces would all be connected. I figured this out as I was building which proved to be a valuable learning experience. This model took a total of about three days to design, about eight hours to build, and an overall two months to complete. Model completed May 9, 2011.
At 1,063 ft tall, the Eiffel Tower is equivalent to about eighty-one stories. Although, the tower has only three floors, two of which are on the two platforms, and one at the top. The Eiffel Tower was the tallest man-made structure in the world for forty-one years until the completion of the Chrysler Building in New York City in 1930. But with the addition of a broadcast antenna in 1957, the Eiffel Tower was, once again, taller than the Chrysler Building.
The east leg of the tower. La Tour Eiffel is repainted every seven years to prevent corrosion caused by rust. Each time it is painted, the color may be changed and vary in tint as it increases in height. It is currently painted a shade of brownish-gray and is darkest below the first platform. Between the first and second platforms is a lighter shade, with the lightest shade above the secoond platform. When it is maintained, as much as 50 to 60 tonnes of paint are applied.
The long gray building beside the south leg houses hydraulics that run the lifts which take visitors to the tower's vorious levels. Both the first and second platforms have restaurants on them. The third and highest level is for observation.

The second level, above which the model's lower sixteen flex tubes terminate and are connected to new ones using smooth technic axle connectors. The level's SNOT sides are connected to the platform via four 1x2- 2x2 brackets. This level simply sits on top of the four 4x4 technic liftarm ellipses seen in this picture. Additionally, the aforementioned brackets attach to 1x4 technic liftarms that hold the front corners of each of the lower four legs of the tower together.
The third and final floor of the tower. I used several SNOT techniques including up-side down bricks to accomplish this level's shape.

The model is so lightweight and sturdy that it does not budge when rotated ninety degrees on its z-axis.
At 180 degrees on its z-axis, the Eiffel Tower remains firmly fastened to its pedastal and stays completely stationary.
One last comment on techniques; the first platform is attached to the model's arches by only two 1x1 clips on each side.
This has given me an idea for a building. I'm not sure if it'll work though, and it's not possible to build in LDD. I only have three flex tubes (from the Space Needle set) and need to order about 15 more when I get some extra cash.
Quoting Paul Wellington
Correction eleventh tower overall. Can't wait to see this at Brickworld! I haven't even touched my city in the last six weeks so I really have to hit it hard over the next month.
Thanx for correcting me Paul! Glad you caught that!! And I can't wait to see your city either!
