Bangui Wind Farm

Bangui Wind Farm

From Pagupud, Melissa, Almira, Albert, Jandy and I again rejoined the others in our bus as we returned to Bangui for our much awaited visit to its Wind Farm, fascinating landmark of the town. From the highway, we could already espy these gorgeous giant fans.

Bangui Bay

Bangui Bay

The windmills, officially referred to as the NorthWind Bangui Bay Project, is the first “Wind Farm” in the Philippines and is considered to be the biggest in Southeast Asia. The site, a graceful arc reflecting the 9-km. long and 100 m. wide shoreline of Bangui Bay, create a fusion of technological and natural elegance. Bordering the West Philippine Sea, it has a windswept area of 5,281 sq. m. (56,840 sq. ft.).

Its 20 units of 70-m. (230-ft.) high Vestas V82 1.65 MW wind turbine-generator units (WTGs), all arranged in a single row, were supplied NorthWind Power Development Corp, a Danish power firm.  Spaced 326 m. (1,070 ft.) apart, their three 41 m. (135 ft.) long, vertically-oriented rotor blades, on top of a 50 m. high tubular tower with a 6 m. diameter base, have a rotor diameter of 82 m. (269 ft.). The nacelle (casing), which encloses the generator, the gear box and the yaw mechanism (which turns the blades into the wind), is at the rear of the rotor blades.

The sight of the giant man-made wonders was astonishing and any picture with the windmills, whether near or far, is truly charming. You can come close to them, touch them to feel its vibration but you can’t hug them as they are just too big and wide. A must-try experience, there’s definitely no other place like it in the country. Locals even picnic under them and they could hear the whirring of the blades of these tall and imposing structures from above, all of them rotating in unison.   However, the picturesque beach in the area is not good for swimming as its waves are too strong.

Now a busy tourist spot, along the stretch are restaurants with viewing decks where you can eat and stalls selling souvenirs like windmill key chains, bags, T-shirts, ref magnets, miniature windmills and pen holders. Seaside horseback riding is also being offered here. You can also watch the spectacular sunset and ocean view while listening to crashing of the ocean waves. The best part o our visit here is that there are no entrance fees. You can shoot all you want. There are no restrooms though. Prepare yourself for the unrelenting winds that batter you from the open sea. There’s not much of an adventure there but it’s still worth visiting.

How To Get There From Laoag City, take a Cagayan-bound bus (a 1.5-hour trip) towards Burgos. After reaching Burgos, watch out for the directional marker on the left side of the road that leads to the Bangui Bay. Follow the dirt road leading to the bay. Some wind mills will already be visible from this point then make a right turn to the bay.

Ciudad Victoria

For the second time around (the first was in Mindoro Oriental), I was invited by the Automobile Association of the Philippines (AAP) to join another of their drive tourism caravans (the 10th in AAP’s series), this time to Bulacan. The caravan is a tourism program wherein, instead of driving straight to the destination, it moves through a tourism highway or road network that allows participants to see many attractions in between the start and end destinations.

Participants of the AAP Drive Caravan at the Philippine Arena

With the theme “Enjoying Bountiful Harvest and Exploring the Off Beaten Path of History and Culture,” the 57 participants (AAP directors, members, friends and the media), in 14 cars, flagged off one early morning from the Petron Marilao station where we had breakfast and availed ourselves of their clean restrooms.

The event was co-organized by Petron Blaze 100 Euro 4, in partnership with the Department of Tourism Region 3, the tourism office of Bulacan under Gov. Wilhemino Sy-Alvarado, the Tourism Promotions Board, Manila North Tollways Corp. and Aeromed, the official ambulance partner.

The Philippine Arena

Participants first visited the 140-hectare Ciudad de Victoria (also known as the Philippine Arena Complex), a 140-hectare tourism enterprise zone in Bocaue and Santa Maria that integrates residential and office buildings, as well as a complex dedicated to shopping, entertainment, leisure, education, business and sports.

The Philippine Sports Stadium

Ciudad Victoria, owned by the Iglesia ni Cristo (INC), a Filipino-based indigenous Christian religious organization, through its educational institution, the New Era University, and operated by Maligaya Development Corporation, houses the magnificent Philippine Arena (a 55,000-seater indoor domed arena that is the world’s largest mixed-use indoor arena) and the 20,000-seater Philippine Sports Stadium (the largest stadium in the Philippines). In commemoration of INC’s centennial celebration on July 27, 2014, it was inaugurated, after three years of construction, on July 21, 2014.

Entrance of the Philippine Sports Stadium

Other buildings within the complex include the Eraño G. Manalo (EGM) Medical Center (an 11-storey, 1st class modern hospital which is the first of its kind in Northern Luzon with 1,000-bed capacity) an Iglesia ni Cristo Chapel (dedicated on May 18, 2018) and the New Era University Bocaue Campus. The landscape for the arena and the whole complex of Ciudad de Victoria was designed by PWP Landscape Architecture, the firm who landscaped the National September 11 Memorial & Museum.

The Bridges Along the Seine River (Paris, France)

Posted on by — Leave a reply

The author with Pont Alexandre III in the background

During our Seine River Cruise, on board a popular and modern Bateaux Parisiens glass-topped trimaran, we passed by some of the city of Paris’ major bridges and passerelles (pedestrian footbridges). The city has 37 bridges  across the River Seine of which 5 are pedestrian, 2 are rail bridges, three link Île Saint-Louis to the rest of Paris, 8 do the same for Île de la Cité and one links the 2 islands to each other. The city’s bridges offered us a lesson in history and architecture.  A list follows, from downstream to upstream:

Check out “Seine River Cruise”

Pont d’Iéna

The 155 m. long and 35 m. wide Pont d’Iéna (“Jena Bridge”), linking the Eiffel Tower on the Left Bank to the district of Trocadéro on the Right Bank, was built from 1808 to 1814 and designed with five arches, each with an arc length of 28 m., and four intermediate piers.

Check out “Eiffel Tower”

The tympana, along the sides of the bridge, had been originally decorated with imperial eagles conceptualized by François-Frédéric Lemot and sculpted by Jean-François Mouret. Soon after the fall of the First Empire in 1815, the eagles were replaced with the royal letter “L” but, in 1852, when Napoléon III ascended the throne of the Second Empire, , the royal “L” was replaced new imperial eagles sculpted by Antoine-Louis Barye,

Four sculptures, sitting on top of four corresponding pylons on the two ends of the bridge, were put in place in 1853.  The sculpture of a Gallic warrior (by Antoine-Augustin Préault) and a Roman warrior (by Louis-Joseph Daumas) are along the Right Bank while the sculpture of an Arab warrior (by Jean-Jacques Feuchère) and a Greek warrior (by François Devault) are along the Left Bank. Since 1975, this bridge has been part of the supplementary registry of historic monuments.

The steps leading off the bridge, popularly known among film fans as the “Renault stairs,” was featured in a scene in A View to a Kill where James Bond (played by Roger Moore) drove a hijacked Renault 11 taxi down the steps in pursuit of an assassin, later revealed to be May Day (Grace Jones).

Passerelle Debilly (Debilly Footbridge)

The 125 m. long and 8 m. wide Passerelle Debilly (Debilly Footbridge), a through arch footbridge, connects the quai de New York to the quai Branly, close to the Eiffel Tower. Opened in 1900, it was designed by architect, Jean Résal (who also designed the Pont Alexandre III) and named after General Jean Louis Debilly of the French First Empire who was killed in the Battle of Jena in 1806.

The footbridge, built on a metallic framework resting on two stone piers at the riverbanks, is decorated with dark green ceramic tiles arranged in a fashion that suggests the impression of waves. In 1966, as a contemporary of the Pont Alexandre III and the Austerlitz Viaduct, the Passerelle Debilly was eventually included in the supplementary registry of historical monuments and, along with the Eiffel Tower, is the second metallic structure that stands as an attestation to the engineering achievements of its epoch. In 1991, the bridge was repainted and, in 1997, its cladding was resurfaced with hard tropical wood.  The bridge is located near the Métro station: Iéna.

Pont Alexandre III

The 160 m. long and 40 m. wide Alexandre III Bridge (Pont Alexandre III), a deck arch bridge widely regarded as the most ornate, extravagant bridge in the city, connects the Champs-Élysées quarter with those of the Invalides and Eiffel Tower. Since 1975, the bridge has been classified as a French monument historique.

Nymph reliefs

This  bridge, with its 32 exuberant Art Nouveau  bronze candelabras, cherubs, nymphs and winged horses at either end, was built between 1896 and 1900 and was named after Tsar Alexander III (the second to last emperor of Russia) who, in 1892, concluded the Franco-Russian Alliance. Tsar Nicholas II (his son), Empress Alexandra Fedorovna and French President Felix Faure laid the foundation stone in October 1896. The Beaux-Arts style of the bridge reflects that of the Grand Palais, to which it leads on the right bank.

Statue of Fames Restraining Pegasus

A marvel of 19th century engineering, the bridge was designed by the architects Joseph Cassien-Bernard  and Gaston Cousin, built by engineers Jean Résal and Amédée Alby and was inaugurated in 1900 for the Exposition Universelle (universal exhibition) World’s Fair, as were the nearby Grand Palais and Petit Palais. Consisting of a 6 m. (20 ft.) high single span steel arch, its design was constrained by the need to keep the bridge from obscuring the view of the Champs-Élysées or the Invalides.

Check out “L’Hotel des Invalides”

Sculptures, provided by numerous sculptors, feature prominently on the bridge. Watching over the bridge are four gilt-bronze statues of Fames supported on massive 17 m. (56 ft.) masonry socles, crowned by Fames restraining Pegasus, that provide stabilizing counterweight for the arch, without interfering with monumental views.

The nymph reliefs, at the centers of the arches over the Seine, are memorials to the Franco-Russian Alliance. The Nymphs of the Seine, with a relief of the arms of Paris, faces the Nymphs of the Neva, with the arms of Imperial Russia. Both are executed in hammered copper over forms by Georges Récipon.

Pont des Invalides

The 152 m. long and 18 m. wide Pont des Invalides, the lowest bridge traversing the Seine, was opened in 1855 in time for the upcoming 1855 World Fair in Paris.  Paul-Martin Gallocher de Lagalisserie and Jules Savarin used the existing piers of the former suspension bridge (built in 1829) and a newly added central pier to build an arch bridge in masonry on the same site.

The new pier was adorned with sculptures in two allegorical themes –  Land Victory by Victor Vilain (upriver) and the Maritime Victory by Georges Diébolt (downstream).  The two old piers, adorned with sculptures of military trophies bearing the imperial coat of arms, were both done by Astyanax-Scévola Bosio.

Passerelle Léopold-Sédar-Senghor

The 106 m. long and 15 m. wide Passerelle Léopold-Sédar-Senghor, a footbridge in the 7th arrondissement of Paris, is served by the Metro station Assemblée Nationale. Formerly known as Passerelle Solférino (or Pont de Solférino), it renamed on October 9, 2006 on the centenary of Léopold Sédar Senghor’s birth. Linking the Musée d’Orsay and the Jardin des Tuileries (Tuileries Gardens), the bridge was built between 1997 and 1999 under the direction of the engineer and architect Marc Mimram.

With a single span and no piers, this architecturally unique metallic bridge is covered in exotic Brazilian ipê wood (also used for outdoor flooring at the Bibliothèque nationale de France) which gives it a light and warm appearance.

Its foundations, at either end, are in the form of concrete pillars extending 15 m. into the ground, and the structure itself is made up of six 15- ton components built by Eiffel Constructions Métalliques, the Eiffel engineering company. For the year 1999, its innovative architecture brought Marc Mimram the award “Prix de l’Équerre d’Argent.” For promenaders, the bridge also has benches and lampposts.  They can reach the Jardin des Tuileries through a subterranean passage on the Rive Droite.

Pont Neuf

The 232 m. long and 22 m. wide Pont Neuf (“New Bridge”), the oldest (built from 1578 to 1607) standing bridge across the river Seine, stands by the western (downstream) point of the Île de la Cité, the island in the middle of the river that was, between 250 and 225 BC, the birthplace of Paris (then known as Lutetia) and, during the medieval period, the heart of the city. Since 1889, it has been listed as a monument historique by the French Ministry of Culture.

The bridge is composed of two separate spans.  One, of five arches, joins the left bank to the Île de la Cité.  The other, of seven arches, joins the island to the right bank. At the tip of the island is Square du Vert-Galant, a small public park, nicknamed the “Green Gallant,” named in honor of Henry IV. In 1991, it became a UNESCO World Heritage Site.  From time immemorial, it has appeared in countless paintings and , on this bridge, one can make out previous water levels that broke the Seine’s banks.

Pont au Double

The 45 m. long and 20 m. wide Pont au Double, linking the 4th and 5th arrondissements of Paris, from the Île de la Cité to the quai de Montebello, derives its name from the toll amount which was charged (a “double” denier), money which used to pay for the construction of the bridge. Built in 1883, this one arch cast-iron bridge replaced bridges built from1626 to 1634 (collapsed in 1709, the rebuilt bridge remained in place until 1847).

Pont de la Tournelle

The 122 m. long and 23 m. wide Pont de la Tournelle (Tournelle Bridge), an arch bridge with a 7 m. clearance above the central arch, was built in 1928.  In order to emphasize the shapeless landscape in the part of the Seine that it bestrides, the Pont de la Tournelle was intentionally built lacking symmetry. Its grand central arch, linking the riverbanks via two smaller arches, one on each side, is decorated, on the Eastern bank, with a pylon built on the left pier‘s cutwater.

Statue of St. Genevieve Atop a Pylon

The statue of Saint Geneviève (the patron saint of Paris), atop of the pylon, was designed by Paul Landowski, a Polish-French monumental sculptor .

Pont de Sully

The Pont de Sully  (or Pont Sully), constructed in 1876 (as part of Haussmann’s renovation of Paris), was designed by the engineers Paul Vaudrey and Gustave Brosselin.  Opened on August 25, 1877, it is named after Maximilien de Béthune, Duke of Sully (1560–1641) and minister to Henry IV.

In reality, it is two separate bridges set at an angle of about 45 degrees to the river banks, which means that it gives a splendid view over the quais of the Île Saint-Louis and Notre-Dame. The northern part, over the narrower arm of the river, consists of a central 42-m. arch in cast iron and two 15-m. arches in masonry. It links the island to the rest of the 4th arrondissement on the Right Bank  (the nearest Metro station, Sully – Morland, is located here). The southern part, consisting of three cast iron arches, links the island to the Boulevard Saint-Germain in the 5th arrondissement of Paris on the Left Bank.

Pont Marie

The 92 m. long and 22 m. wide Pont Marie, linking the Île Saint-Louis to the quai de l’Hôtel de Ville, is one of three bridges designed to allow traffic flow between the Île Saint-Louis and the Left and Right banks of Paris. Linking the Right Bank, the Pont Marie is the counterpart of the Pont de la Tournelle which is built along the same line but serves to connect the Île Saint-Louis with the Left Bank.  Started in 1614 and opened in 1635, it was designed by
Rémy Collin, Jean Delgrange, Christophe Marie (after whom the bridge was named after) and reconstructed in 1670.  Each of its five arches is unique and the niches in the abutments have never been filled with statues.

Pont de l’Archevêché

The 68 m. long and 17 m. (11 m. usable) wide Pont de l’Archevêché  (Archbishop’s Bridge), linking the 4th Arrondissement, at the Île de la Cité, to the 5th Arrondissement (between the quai de Montebello and the quai de la Tournelle), is the narrowest road bridge in Paris.  Located near the Métro station: Maubert-Mutualité, It was built in 1828 by the engineer Plouard and is composed of three arches of stone measuring lengths of 15 m. (49 ft.), 17 m. (56 ft.) and 15 m. (49 ft.).

Pont Saint Louis

The 67 m. long and 16 m. wide Pont Saint-Louis (3:34 PM), in the 4th arrondissement, links the Île de la Cité (the seventh to link the two islands since 1630) with the Île Saint-Louis. Started in 1969 and inaugurated in 1970, the bridge is served by the Cité stop of the Paris Metro.

The Eiffel Tower

The Eiffel Tower

The Eiffel Tower has become both a global cultural icon of France and one of the most recognizable structures in the world. This iron lattice tower, located along the Champ de Mars, was named after the French engineer Alexandre Gustave Eiffel, whose company designed and built the tower in 1889. Erected as the entrance arch to the 1889 World’s Fair (which celebrates the 100th anniversary of the French Revolution), it was started on  January 26, 1887, completed on March 15, 1889 and opened on March 31.

It was initially criticized by some of France’s leading artists and intellectuals for its design (saying it had too much engineering and not enough art to be considered good architecture) but now is widely considered now to be a striking piece of structural art, often featured in films and literature. Here are also some interesting trivia regarding the Eiffel Tower:

  • Gustave Eiffel did not design the Eiffel Tower – senior engineer Maurice Koechlin did.
  • The design for the tower was decided by a contest. Contestants had to submit their designs for consideration. Eiffel’s design won.
  • It took 3 years of lobbying to approve the Eiffel Tower in 1887.
  • Public funds only covered a quarter o the cost of the Eiffel Tower.
  • On February 14, 1887, all the big names of the world of arts and literature, including Charles Garnier (who built the famed Opera house), Guy de Maupassant, Alexandre Dumas Jr., Leconte de Lisle, and Sully Prudhomme, united to stop its construction in what is known as the ‘Artists Protests.”
  • Eiffel’s firm produced 5,329 drawings (1,700 generals an 3,629 detailed) of the Eiffel Tower
  • Only one person died in the construction of the Eiffel Tower
  • The French name for the Eiffel Tower is La Tour Eiffel. It also has the nickname La dame de fer which means “the iron lady,” the same nickname as Margaret Thatcher’s.
  • Famed novelist Guy de Maupassant hated the tower but ate lunch there every day. When he was asked why, Maupassant answered that the only place in Paris where he couldn’t see the Eiffel Tower was the Eiffel Tower itself.
  • It is the most-visited paid monument in the world.
  • The tower, the tallest structure in Paris and the  second tallest structure in France (not including broadcast aerials), after the Millau Viaduct (completed in 2004, the world’s tallest bridge is  taller, at 343 m.). It was the tallest until the construction of a military transmitter in the town of Saissac in 1973.
  • During its construction, the Eiffel Tower surpassed the 555-ft. high Washington Monument to assume the title of the tallest man-made structure in the world, a title it held for 41 years, until the Chrysler Building in New York City was built in 1930. In 1957, after the addition of the aerial, the Eiffel Tower it is now taller than the Chrysler Building by 5.2 m. (17 ft.).
  • Famous visitors to the tower during its opening included The Prince of Wales, Sarah Bernhardt, “Buffalo Bill” Cody (his Wild West show was an attraction at the Exposition) and Thomas Edison.
  • Eiffel had a private apartment for entertaining friends at the third floor of the tower. He  made use of his apartment at the top level of the tower to carry out meteorological observations, and also made use of the tower to perform experiments on the action of air resistance on falling bodies.
  • Gustave Eiffel was also behind the design of the Garabit Viaduct (1884), the Pest Railway Station in Hungary, the dome of the Nice Observatory and the interior elements for the Statue of Liberty‘s spine. He was also involved in a disastrous attempt by the French to build a canal in Panama, and his reputation was badly damaged by the failure of the venture. He died while listening to Beethoven‘s 5th symphony.
  • The Eiffel Tower was originally intended for Barcelona, Spain, but the project was rejected.
  • It served as a military radio post in 1903, transmitted the first public radio program in 1925, and then broadcast television and digital TV.
  • Sir John Bickerstaffe, Mayor of Blackpool and an attendee at the 1889 World’s Fair, was so impressed with the Eiffel Tower that, in 1891, he had a similar structure (Blackpool Tower) designed and built on the English seafront to surpass the Eiffel Tower in height.  However, it was unsteady, never completed and demolished in 1907.
  • Eiffel’s permit for the tower allowed it to stand for only 20 years (it was to be dismantled in 1909, when its ownership would revert to the City of Paris). As part of the original contest rules for designing a tower was that it should be easy to demolish, the city had planned to tear it down. However, the tower was proved valuable for communication purposes (it was repurposed as a giant radio antenna) so it was allowed to remain even after the expiry of the permit.
  • In 1905, local newspaper L’Equipe organized a stair climbing championship at the tower. A M. Forestier won a bike, taking three minutes and 12 seconds to reach the second level.
  • On February 4, 1912, French tailor Franz Reichelt attempted to fly from the first floor with a spring-loaded parachute suit of his own design. However, he crashed 187 ft. to the ground instead.
  • During World War I, using the Eiffel Tower’s wireless station to intercept enemy messages from Berlin, the French military, in 1917, intercepted a coded message between Germany and Spain that included information about ‘Operative H-21’ otherwise known as the Dutch-born exotic dancer Margaretha Geertruida Zelle  MacLeod (stage name: Mata Hari) who was spying for the Germans. Based on this message, the French were able to arrest, convict and execute Mata Hari for espionage.
  • At the First Battle of the Marne, in 1914, the tower played a part in the Allied victory when one of its transmitters jammed German radio communications, hindering their advance.
  • By 1918, after Guillaume Apollinaire made a nationalist poem in the shape of the tower (a calligram) to express his feelings about the war against Germany, it became a symbol for Paris and for France
  • In 1923, Pierre Labric cycled down the stairs of the tower, winning a bet but was arrested by local police.
  • On February 28, 1926, 23 year old French aviator Leon Collot attempted to fly his plane under the tower but was killed when he was blinded by the sun and became entangled in the aerial from the wireless station, crashing in a ball of flame.
  • On 2 separate occasions in 1925, con artist Victor Lustig, pretending that he was the deputy director-general of the Ministry of Posts and Telegraphs, “sold” the Eiffel Tower to a scrap metal dealer.
  • Between 1925 and 1934, French car manufacturer Citroen used the tower as a giant billboard (recorded as the world’s biggest advertisement by the Guinness Book of Records), the company name was emblazoned on the tower using a quarter of a million light bulbs.
  • During the German Occupation in World War II, when Adolf Hitler visited Paris, the French cut the lift cables on the Eiffel Tower so that he would have to climb the steps if he wanted to reach the top. Nazi soldiers also attempted to attach a swastika to the top, but it was so large it blew away and had to be replaced with a smaller one.
  • In 1944, as the Allies approached Paris, Hitler ordered Gen. Dietrich von Choltitz, the military governor of Paris, to demolish the tower, along with other parts of the city. The general refused.
  • In 1960, Charles de Gaulle proposed temporarily dismantling the tower and sending it to Montreal for Expo 67. The plan was rejected.
  • In the Beatles song I Am the Walrus, Semolina Pilchard climbs the Eiffel Tower.
  • For its 75th anniversary, there was a televised broadcast of mountaineers climbing up the tower.
  • The tower appears in the 1985 Bond film A View to a Kill. There is a scene in the Jules Verne Restaurant, and a fight in the stairway.
  • In 2007, a woman with an objects fetish named Erika La Tour Eiffel “married” the Eiffel Tower, changing her name to Erika La Tour Eiffel in honor of her “partner.”
  • According to the Societe de la Tour Eiffel, since the tower first opened in 1889, there have only been 349 successful suicides. Some were jumpers, while others were people hanging themselves from the beam. Those who did attempt to jump from the first level don’t always die.
  • At night, it is illegal (you can be fined) to take a photograph of the tower because the light display is considered artwork and therefore protected under copyright law.
  • Zoning restrictions in Paris limit the height of most buildings to 7 storeys high. Thus, only a small number of taller buildings have a clear view of the tower.
  • The Eiffel Tower being so popular, its design has been recreated around the world, with over 30 replicas including the half scale replica at the Paris Las Vegas Hotel in Nevada, USA, the full scale Tokyo Tower in Japan and one at the Window of the World theme park in Shenzhen, China.
  • To counteract atmospheric perspective, multiple types of colors are used to paint the Eiffel Tower. Darker shades are used at the top and, gradually, lighter hues are painted toward the bottom.
Names of 70 scientists and engineers inscribed in surrounding panels

Names of 70 scientists and engineers inscribed in surrounding panels

  • The names of 72 engineers, scientists and mathematicians are engraved on the side of the tower, each of whom contributed to its construction.
  • To mark the 125th anniversary of the Eiffel Tower’s completion, the British Virgin Islands has launched a special tower-shaped $10 coin.
  • In the computer game Call of Duty: Modern Warfare 3, the tower is toppled by an airstrike.
  • Lego set number 10181, containing 3,428 bricks, are for those who wanted to build your own Eiffel Tower.
  • To keep the operations up and running 365 days a year, the site requires a large staff of 280 people.
  • To validate admission, cashiers sell 2 tons of tickets every year and the cleaning crew uses 25,000 garbage bags annually.
  • More than just a tourist attraction, the tower also houses gourmet restaurants, art exhibitions, concerts, a newspaper office, a post office, scientific laboratories, and the first level becomes an ice rink every year.
  • In 1984, two Britons parachuted from the tower without permission.
  • The Eiffel Tower Light Display, dating back to 1985, was invented by Pierre Bideau, an electrician and lighting engineer. Consisting of projectors equipped with high-pressure, yellow-orange sodium lamps, when illuminated, they give the impression that the Eiffel Tower is sparkling with gold. In under 10 mins., the projectors are turned on and activated by sensors. In 2004, they were replaced with energy-efficient projectors, resulting in 40% energy savings.
  • For the landmark’s centennial, tightrope walker Philippe Petit walked the 2,296 ft. between the Palais de Chaillot and the Eiffel Tower.
  • In 2002, Hugues Richard climbed the tower on his mountain bike , breaking his own 1998 record.

Here are some amazing facts about the tower:

  • The Eiffel Tower is 324 m. (1,063 ft. including antenna) tall (about the same height as an 81-storey building) and its base is square, 125 m. (410 ft.) on a side.
  • 98 million people ascended it in 2011 and the tower received its 250 millionth visitor in 2010. In 2012, there were 6,180,000 visitors (75% foreign) and an average of 25,000 people ascend the tower every day. The majority of visitors are French (10.4%), followed by Italy and Spain (8.1% each), USA (7.9%), Britain (7.4%), Germany (5.8%) and Brazil (5.5%).

  • The tower has three levels for visitors, with restaurants (including the internationally renowned Jules Verne Restaurant) on the first and second. The third level observatory’s upper platform, the highest accessible to the public in the European Union, is 276 m. (906 ft.) above the ground,
  • 1,665 steps are needed to climb all the way to the top of the Eiffel Tower. The climb from ground level to the first level (187 ft.) is over 300 steps, as is the walk from the first to the second level.   The height of the third level is 905 ft.
  • There are 336 floodlights and 20,000 (5,000 per side) special light bulbs that twinkle (for 5 mins. on the hour, every hour, from nightfall to 1 AM) on the Eiffel Tower. Its light beam can be seen 50 miles away. 25 mountain climbers were required for the 5-month lighting installation. 50 miles of electrical cable and 60 tons of metallic parts cover the tower. Total cost was over $5 million
  • Its 6 elevators make 100 climbs per day. Every year, elevator trips total 103,000 kms. (64,000 mi.), enough to go around the globe 2.5 times.
  • Annually, it consumes 7,500,000 KWH of electricity, the same amount of electricity used by a small village annually.
  • Every 7 years, around 50 to 60 tons (49 to 59 long tons; 55 to 66 short tons)of paint, weighing as much as 10 elephants, are needed to paint the 2,690,750 sq. ft. surface of the Eiffel Tower to protect it from rust.
  • It cost 7,799,401 gold francs to build. If the Eiffel Tower was built today, it would cost about US$35 million.
  • It took a total of 2 years, 2 months and 5 days to build 180 years fewer than Paris’s other great attraction, Notre Dame Cathedral.
  • Despite its height, the Eiffel Tower was designed to be wind resistant, swaying only a few inches in the wind.
  • Depending on the ambient temperature, the top of the tower may shift away from the sun by up to 18 cm. (7.1 in.) because of thermal expansion of the metal on the side facing the sun.
  • The Eiffel Tower weighs 11,133 tons, around 7,300 of which represents the metallic structure..
  • The height of the Eiffel Tower varies by 15 cm. (5.9 in.) due to temperature.
  • 300 workers, 18,038 pieces of wrought iron and 2.5 million rivets were needed to build the Eiffel Tower.
  • The puddled iron (wrought iron) structure of the Eiffel Tower weighs 7,300 tons, while the entire structure, including non-metal components, is approximately 10,000 tons. If the 7,300 tons of the metal structure were melted down it would fill the 125-m. square base to a depth of only 6.25 cm. (2.5 in.), assuming the density of the metal to be 7.8 tons per cu. m.
  • A cubic box surrounding the tower (324 m. x  125 m.  x  ) would contain 6,200 tons of air, almost as much as the iron itself.

Louvre Pyramid (Paris, France)

Louvre Pyramid

The Louvre Pyramid

At the main courtyard (Cour Napoléon) of the Louvre Palace (Palais du Louvre) is the Louvre Pyramid (Pyramide du Louvre), a large, glass and metal pyramid that serves as the main entrance to the Louvre Museum. Designed by the late Chinese-American architect I. M. Pei (Ieoh Ming Pei), the founder of Pei Cobb Freed & Partners known for his stellar work at the National Gallery in Washington as well as the Fine Arts Museum in Boston.

It was commissioned in 1984 by the, François Mitterrand, President of France, and completed on March  29, 1989 (symbolically, the bicentenary year of the French Revolution).

I.M. Pei’s most famous structure, this controversial structure, now an iconic symbol for the largest museum in the world,  has become, together with the Arc de Triumphe and the equally controversial Eiffel Tower, a landmark of the city of Paris.

One of the three smaller pyramids

Here are some interesting trivia regarding the Louvre Pyramid:

  • There are actually five pyramids throughout the museum. The Louvre Pyramid is surrounded by three smaller pyramids, positioned to create light shafts for access to the museum’s collections, plus the Pyramide Inversée (Inverted Pyramid), an upside-down and smaller version of the Louvre Pyramid. The latter is a skylight in the Carrousel du Louvre shopping mall in front of the Louvre Museum.
  • The large pyramid has the exact same proportions as the Great Pyramid of Giza.
  • The choice of the pyramid figure serves as a reminder of the importance of the Egyptian antiquities collection inside the museum.
  • The Louvre Pyramid was featured near the beginning the 2006 film The Da Vinci Code. Here, Robert Langdon, the main character, meets French Police Captain Bezu Fache in front of the Louvre Pyramid. Today, the sites at the Louvre which are portrayed in the film are the subject of a special visitor trail which enters through the Pyramid and concludes at the Inverted Pyramid.
  • Because of a series of problems with the Louvre’s original main entrance (it could no longer handle, on an everyday basis, the enormous number of visitors, then at 5 million visitors a year), the Louvre Pyramid was created so that visitors entering through the pyramid first descend into the spacious, 60,386 sq. m. (650,000 sq. ft.) underground lobby before ascend into the museum’s three pavilions — Denon, Richelieu and Sully.  However, in 2014, the Louvre’s attendance had doubled and the pyramid proved inadequate, necessitating a thorough redesign of the layout of the foyer area in the Cour Napoleon, including better access to the pyramid and the Passage Richelieu, between 2014 and 2017.
  • As soon as the Louvre Pyramid project, costing 5 billion euros, was announced, it triggered many years of strong and lively aesthetic and political debate. Accused of disfiguring the architecture, some questioned what direction the museum was headed. They criticized the Modernist style of the edifice being inconsistent with the majestic, old and classic French Renaissance architectural style and history of the Louvre; the pyramid being an unsuitable and anachronistic intrusion of an ancient Egyptian symbol of death in the middle of Paris; the hugely unpopular project being an immodest, pretentious, megalomaniacal folly imposed by then-President François Mitterrand (political critics referred to the structure as “Pharaoh Francois’ Pyramid”); and that Chinese-American architect I.M. Pei being insufficiently French to be entrusted with the task of updating the treasured Parisian landmark. Even today, many people still feel that the harsh modernism of the edifice is out of place.
  • M. Pei also included large glass pyramid concept on the roofs of the IBM Somers Office Complex(Westchester County, New York, 1989, the same year the Louvre Pyramid opened) and at the Rock and Roll Hall of Fame (1995, Cleveland, Ohio).
  • Several other museums have also duplicated the pyramid concept, most notably the Museum of Science and Industry(Chicago, Illinois) and the Dolphin Centre (opened April 1982, by Prince Richard, Duke of Gloucester).
  • It has been claimed by some that the glass panes in the Louvre Pyramid number exactly 666, “the number of the beast” often associated with Satan and the beast in the Apocalypse. Dominique Stezepfandt’s book François Mitterrand, Grand Architecte de l’Universalso declares that “the pyramid is dedicated to a power described as the Beast in the Book of Revelation (…) The entire structure is based on the number 6.” The story of the 666 panes originated in the 1980s, when the number 666 was mentioned in various newspapers as well as the official brochure published during construction (even twice, though, in a few pages earlier, the total number of panes was given as 672 instead). In 2003, the myth resurfaced when Dan Brown incorporated it in his best-selling novel The Da Vinci Code.  In the book, the protagonist reflects that “this pyramid, at President Mitterrand’s explicit demand, had been constructed of exactly 666 panes of glass.”  However, the Louvre museum states that the finished pyramid contains 673 glass panes (603 rhombi and 70 triangles). David A. Shugarts obtained a higher figure from Pei’s offices, reporting that the pyramid contains 689 pieces of glass.
  • During the design phase, there was a proposal that the design include a spire on the pyramid to simplify window washing. However, Pei objected and this proposal was eliminated.
  • Just in case any glass pieces ever break, laminated glass manufacturer Saint-Gobain made enough to build two pyramids. However, after more than 30 years, no repairs have yet been needed.
  • In the early days, mountaineers were actually hired to scale the Pyramid and clean the glass, a monumental task. However, in the 1990s, a robot was designed to do the job. Then, in 2002, Advanced Robotic Vehicles, a Seattle company, developed a “double breadboxed-sized robot” which boasts a squeegee and rotating brush. When secured to the glass via suction cups, it is maneuvered by remote control to climb the Pyramid on tracks. However, human ropers are still used to repair the joints and descale the glass from time to time.
  • Although the Pyramid was constructed to accommodate a visitor entrance, it’s not the only way to get into the Louvre. Visitors, with single or group tickets, can enter through the Passage Richelieu, which is just off the Rue de Rivoli across from the Palais Royal-Musée du Louvre metro station. You can also enter via the Carrousel du Louvre, an underground shopping and dining space opened in 1993 and the location of the suspended Inverted Pyramid. Whichever entrance you choose, they all converge in the lobby beneath the Louvre Pyramid.

The underground lobby

Constructed entirely with 21.5 mm. (0.8-in.) thick, extra clear “Diamond Glass” laminated glass segments, totaling 1,800 sq. m. (19,375 sq. ft.) in area, and 6,000 metal poles, the structure, supported by 95 tons of steel and 105 tons of aluminum, is 21.6 m. (71 ft.) high and its square base has sides of 34 m. (112 ft.) and a base surface area of 1,000 sq. m. (11,000 sq ft.).

Spiral stair

Consisting of 603 rhombus-shaped and 70 triangular glass segments, elementary arithmetic allows for easy counting of the panes.  Each of the three sides of the pyramid without an entrance has 18 triangular panes and 17 rows of rhombic ones arranged in a triangle, thus giving rhombic panes (171 panes total).

The side with the entrance has 11 panes fewer (9 rhombic, 2 triangular), so the whole pyramid consists of rhombi and triangles, 673 panes total.

The pyramid structure was engineered by Nicolet Chartrand Knoll Ltd. of Montreal (Pyramid Structure/Design Consultant) and Rice Francis Ritchie of Paris (Pyramid Structure/Construction Phase).

Notre Dame Cathedral (Paris, France)

Notre Dame Cathedral

Notre Dame Cathedral

We arrived at Paris’ Charles de Gaulle International Airport on a Sunday morning and, after checking in at the Ibis Paris Gare de l’Est 10th, we decided to hit two birds with one stone by taking the Paris Metro to get to the historic  Notre Dame Cathedral, among the largest and most well-known church buildings in the world, where we plan to hear Mass and do sightseeing later.  It was already raining when we left the hotel and, when we arrived,we still had to queue to get into the cathedral through the right door.  The Gregorian Mass we attended was said in French.

The Gothic-style facade

The Gothic-style facade

The magnificent, awe-inspiring Notre-Dame Cathedral, also called  Notre Dame de Paris, (French for “Our Lady of Paris”) or simply Notre-Dame, is widely considered to be one of the finest examples of French Gothic architecture, its pointed arches, thinner walls and the naturalism of its sculptures and stained glass  in stark contrast with earlier Romanesque architecture. The cathedral treasury is famous for its reliquary which houses some of Catholicism‘s most important first-class relics including the purported Crown of Thorns, a fragment of the True Cross, and one of the Holy Nails. The cathedral, with a cruciform plan, was made famous by Victor Hugo’s famous, larger-than-life novel “The Hunchback of Notre-Dame” (about the hunchback bell ringer, Quasimodo, who falls madly in love with the beautiful gypsy dancer, Esmerelda). Notre-Dame is composed of a choir and apse, a nave with double aisles and square chapels. It is 226 ft. high, 420 ft. long and has a total surface area of 5,500 sq. m. (interior surface 4,800 sq. m.).

Construction of the cathedral began in 1163, during the reign of Louis VII. Bishop Maurice de Sully devoted most of his life and wealth to the cathedral’s construction. Throughout the construction period, numerous architects worked on the site resulting in differing styles at different heights of the west front and towers. The choir was built from 1163 until around 1177 and the new High Altar was consecrated in 1182. After Bishop Maurice de Sully’s death in 1196, Eudes de Sully (no relation), his successor, oversaw the completion of the transepts.

He also pressed ahead with the construction of the nave which was, at the time of his own death in 1208, nearing completion. The western facade had also been laid out by this stage but it was not completed until around the mid-1240s.   Between 1210 and 1220, the fourth architect oversaw the construction of the level with the rose window and the great halls beneath the towers. The cathedral was essentially complete by 1345.

The rose window

The magnificent rose window

In the mid 13th century, the transepts were remodeled in the latest Rayonnant style and, in the late 1240s, Jean de Chelles added a gabled portal to the north transept, topped off by a spectacular rose window. Shortly afterwards, from 1258, Pierre de Montreuil did the same on the southern transept. Both transept portals were richly embellished with sculpture.  The south portal features scenes from the lives of St Stephen and of various local saints, while the north portal featured the infancy of Christ and the story of Theophilus in the tympanum, with a highly influential statue of the Virgin and Child in the trumeau.

In 1548, features of Notre-Dame were damaged by rioting Huguenots  who considered them  idolatrous. During the reigns of Louis XIV and Louis XV, as part of an ongoing attempt to modernize cathedrals throughout Europe, the cathedral underwent major alterations. In 1786, a colossal statue of St Christopher, standing against a pillar, near the western entrance, and dating from 1413, was destroyed, as well as tombs and stained glass windows.  However, the north and south rose windows were spared.

The cathedral interior

In the 1790s, during the radical phase of the  the French Revolution , many of Notre-Dame’s religious imagery and treasures were either damaged, destroyed or plundered. For a time, Lady Liberty replaced the Virgin Mary on several altars. The 13th century spire was torn down and the statues of the biblical kings of Judah , located on a ledge on the facade of the cathedral, were beheaded as they were erroneously thought to be kings of France. Many of the heads were found during a nearby 1977 excavation and are now on display at the Musée de Cluny. However, the cathedral’s great bells managed to avoid being melted down.  In 1793, the cathedral was rededicated to the Cult of Reason, and, later, to the Cult of the Supreme Being. The cathedral came to be used as a warehouse for the storage of food.

In 1845, a controversial  and extensive  25-year restoration program was initiated and overseen by architects Jean-Baptiste-Antoine Lassus and Eugène Emmanuel Viollet-le-Duc (responsible for the restorations of several dozen castles, palaces and cathedrals across France, he always signed his work with a bat). The restoration included a taller and more ornate reconstruction of the flèche (a type of spire) as well as the addition of the chimeras on the Galerie des Chimères.

Stained glass windows

The very beautiful stained glass windows

During the Second World War, several of the stained glass windows on the lower tier were hit by stray bullets but were remade after the war.  They now sport a modern geometrical patterns not the old scenes of the Bible.  In 1991, a major program of maintenance and further restoration intended to last ten years was initiated.  It included the cleaning and restoration of old sculptures which is an exceedingly delicate matter. By 2014, much of the lighting was upgraded to LED lighting.

Among the first buildings in the world to use the flying buttress (arched exterior supports), Notre-Dame was not originally designed to include the flying buttresses around the choir and nave.  However, after the construction began, the thinner walls grew ever higher and stress fractures began to occur as the walls pushed outward. To remedy this, the cathedral’s architects built supports around the outside walls.  Later additions continued the pattern.

Around the exterior, many small, individually-crafted statues, including the famous gargoyles and chimeras, were placed to serve as column supports and water spouts. Most of the exterior as well as the statues were originally vividly colored but the paint has since worn off, exposing the  gray stone.

As we were on a tight schedule, we didn’t have time to join the extremely long queue climbing several narrow (387 step total, no elevator) spiral staircases, in 3 stages, to the top of the 90 m. high South Tower.  Upon reaching the top, it is possible to view, in close quarters, the cathedral’s Emmanuel Bell, the largest and most famous bell, the flying buttresses and its gargoyles as well as have a spectacular view of the Ile de la Cite. At Notre-Dame, there are 14 millions visitors per year or an average of 40,000 tourists per day.The area around the cathedral has lots of book stalls and cafes.

One of several interesting things I did see around Notre Dame was the huge bronze equestrian statue of Charlemagne et ses Leudes (Charlemagne and his Guards), created by brothers Louis and Charles Rochet in 1878. Charlemagne, the King of the Franks and the emperor of the Holy Roman Empire from 800 A.D. until his death in 814 A.D., is holding a lance or staff while being guided by two leudes, which are believed to be the figures of Oliver and Roland.  Also within the square in front of the cathedral is the Zero Point Marker where all mile markers start from.

Ambuklao Dam (Bokod, Benguet)

Posted on by — Leave a reply

After lunch and freshening up at Ambangeg Country Road Restaurant in Bokod,  we continued on our way back, along winding zigzag roads, to Baguio City.  About 36 kms. (22 mi., an hour’s drive) northeast of the city, we made a short stopover at Ambuklao Dam, in Brgy. Ambuklao.

Ambuklao Dam

Ambuklao Dam

One of Southeast Asia’s earth and rock-filled dams, is is one of the oldest power plants in the country and was among the first large hydroelectric power plants constructed in the Philippines. It impounds the waters of the upper portion of the turbulent Agno River (the longest waterway in Northern Luzon) which originates from Mt. Data, and its tributary, the Bokod River.

The adjunct irrigation system on the delta of the Agno River, it was the first in the Philippines to be served from a reservoir dam and it dams the river with 6,504,000 cu. m. of rocks, gravel and cement together with 1,000,000 cu. m. of clay earth at its core.  Its picturesque, manmade lake has a small picnic area along the shore (no restaurants though) and boats can sometimes be hired for pleasure rowing.  It is also teems with freshwater fish such as crimson snapper (maya-maya), tilapia and silver carp.

Ambuklao View Deck

Ambuklao View Deck

The dam, once ranked among the world’s tallest dams, is 131 m. high, 426 m. long at the crest and has a base width of 565 m..  The elevation of its crest is 758 m. and the roadway that runs through the top of the dam has an elevation of 756 m.. It was once the highest power dam in Asia and the second highest of its kind in the world.

Ambuklao Dam and Lake (8)

As early as the late 1940s, the development of the Agno River, for purposes of hydroelectric power generation, flood control and irrigation, had been conceived and preliminary investigations for development at Ambuklao and Binga Dam sites were undertaken, under the direction of Pres. Manuel A. Roxas, (in cooperation with Westinghouse International) as early as January 1948.

The dam's spillway

The dam’s spillway

Started in July 1950, it took 6 years and 5 months, at a cost of PhP132 million, to complete and the operation of this hydroelectric facility finally started on December 23, 1956. Its civil works contractor was the Guy F. Atkinson Company and the engineering consultant was Harza Engineering Company of Chicago. To build this engineering feat, a diversion channel was first cut to allow the Agno River to flow naturally away from ongoing work.  Then the gorge was narrowed through a series of blasts inside a mountain, thus trapping the water and forming a manmade lake.  Its water turbines, loaded on huge flatbed trucks (operating in tandem), was brought up the coast via the Naguilian Rd. and brought down via the specifically-built Ambuklao Rd. from Pacdal (Baguio City).

Tainter gates

The 8 Tainter radial gates

The dam has 8 Tainter radial gates at the dam’s spillway. Each spillway measures 12.5 m. by 12.5 m. and is 127 m. in length. The gross storage capacity of the dam’s reservoir is 327,170,000 cu. m. (265,240 acre·ft) and it has a usable storage capacity of 258,000,000 cu. m.. The drainage area is 686 sq. kms. and is 11 kms. long with a maximum width of 1 km..  It once generated 75 megawatts (MW) via three 25 MW generating units placed in an underground 17-m. high, 30-m. long and 9-m. wide power house cut from the solid rock.

Manmade Ambuklao Lake

Manmade Ambuklao Lake

On July 16, 1990, a massive earthquake hit Luzon, damaging the dam’s spillways, turbines and reservoir, resulting in siltation and technical problems that affected the plant’s operations.  In 1999, the Ambuklao Dam was decommissioned.  However, on November 28, 2007, SN Aboitiz Power-Benguet, Inc. (SNAP-Benguet), a joint venture between SN Power of Norway and Aboitiz Power, won the public bid for Ambuklao Dam and Binga Dam, its neighboring power facility in Itogon, which were sold (for US$325 million) as a package under the power sector privatization program of the Philippine government.

Transmission towers bring power from the dam to the Luzon grid

Transmission towers bring power from the dam to the Luzon grid

In December 2008, SNAP-Benguet began a massive rehabilitation project that restored Ambuklao Dam to operating status, increasing its capacity from 75 MW to 105 MW. The project required the construction of a new intake, headrace and penstock, elevation of tailrace tunnel outlet, de-silting of tailrace tunnel and replacement of electro-mechanical components. On June 1, 2011, Unit 3 became the first turbine unit to go on-line, followed by the other two units. On October 2011, Ambuklao Dam was formally inaugurated. Ambuklao Dam, designed as a peaking plant, is capable of delivering energy and providing ancillary services needed to maintain the grid.

The Taipei 101 Building (Taiwan)

Posted on by — 1 Comment ↓

The rain had stopped when we returned to the mall and, after snacks at a MacDonald’s outlet at Jason’s Marketplace, the mall’s 1,000-pax basement foodcourt, Jandy, Isha and I exited the building to avail of this window of opportunity.  We all walked, some distance, to a nearby park to appreciate the enormity and grandeur of the 357,721 sq. m. Taipei 101, the first record-setting skyscraper to be constructed in the 21st century. From afar, its repeated segments and inclined  tiers simultaneously recall the rhythms of an Asian pagoda, a tower linking earth and sky (also evoked in the Petronas Towers of Kuala Lumpur, Malaysia)’ a stalk of bamboo, an icon of learning and growth (also emphasized by  its blue green-tinted windows) or a stack of ancient Chinese ingots or money boxes, a symbol of abundance.

Our worm’s eye view of Taipei 101 Building

In 2004 (until the opening of the Burj Khalifa in Dubai in 2010), Taipei 101, formerly known as the Taipei World Financial Center (until 2003), was officially ranked as the world’s tallest  building, displacing the Petronas Towers in Kuala Lumpur, Malaysia (check out my visit here at http://worldstotrek.wordpress.com/2010/12/31/kuala-lumpur-new-years-day/), by 56.1 m (184 ft).  It also displaced the 85-storey, 347.5 m. (1,140 ft.) high Tuntex Sky Tower in Kaohsiung as the tallest building in Taiwan and the 51-storey, 244.2 m. (801 ft.) high Shin Kong Life Tower as the tallest building in Taipei. That same year, it also  received the Emporis Skyscraper Award. In July 2011, the building was awarded the Leadership in Energy and Environmental Design (LEED Platinum certification, becoming the tallest and largest green building in the world.  Its own roof and façade recycled water system meets 20–30% of the building’s water needs.

Curled ruyi figures, appearing throughout the structure as a design motif, are ancient symbols associated with heavenly clouds that connote healing, protection and fulfillment. Each ruyi ornament on the exterior of the Taipei 101 tower stands at least 8 m. (26 ft.) tall.

An icon of modern Taiwan ever since its opening, the structure appears frequently in travel literature and international media.  Taipei 101 was designed by C.Y. Lee & Partners and  constructed primarily by Samsung C&T and KTRT Joint Venture.   It  comprises 106 floors, 101 above ground and 5 floors underground.

The circular motif, the “zero” in Taipei 101, is also the shape of a traditional Chinese coin, a potent symbol of wealth

Architecturally created as a symbol of the evolution of technology and Asian tradition, this building’s Post Modernist approach to style incorporates traditional design elements and gives them modern treatments. Designed to withstand typhoon and earthquakes, Taipei 101, upon its completion, claimed the official records for:

  • Ground to highest architectural structure (spire): 508 m. (1,667 ft.). Previously held by the Petronas Towers 451.9 m. (1,483 ft.), the record  now rests with the Burj Khalifa in Dubai (UAE): 828 m (2,717 ft).
  • Ground to roof: 449.2 m. (1,474 ft.). Formerly held by the Willis Tower‘s 442 m (1,450 ft), the record briefly passed to the Shanghai World Financial Center in 2009 which, in turn, yielded it to the Burj Khalifa.
  • Ground to highest occupied floor: 438 m. (1,437 ft.). Formerly held by the Willis Tower 412.4 m. (1,353 ft.), the record also briefly passed to the Shanghai World Financial Center and then to the Burj Khalifa. .
  • Fastest ascending elevator speed: designed to be 1,010 m. per min., which is 16.83 m./sec. (55.22 ft./sec.) (60.6 kms./hr., 37.7 miles/hr.),  34.7% faster than the 12.5 m. (41 ft) per second (45.0 kms./hr., 28 mile/hr.) speed of Yokohama Landmark Towers‘ elevator, the previous record holder.
  • Largest countdown clock which was displayed on New Year’s Eve (fireworks launched from Taipei 101 also feature prominently in international New Year’s Eve broadcasts).
  • Tallest sundial: The  design of  circular Millennium Park, which adjoins Taipei 101 on the east, allows it to double as the face of a sundial. The tower itself casts the shadow to indicate afternoon hours for the building’s occupants.
  • Taipei 101 is the first building in the world to break the half-kilometer mark in height.

Taipei 101 Tuned Mass Damper (Taiwan)

Posted on by — 1 Comment ↓

From the Inner Observatory, Jandy, Isha and I proceeded to see Taipei 101’s much publicized, massive Tuned Mass Damper (TMD).   Also called a harmonic absorber, a tuned mass damper is a device mounted in structures to reduce the amplitude of mechanical vibrations, moving in opposition to the resonance frequency oscillations of the structure by means of springs, fluid or pendulums. Their application can prevent discomfort, damage or outright structural failure. Taipei 101’s TMD was specially designed to reduce movement caused by strong gusts of wind.  This motion can be in the form of swaying or twisting, and can cause its upper floors to move more than a meter. Certain angles of wind and aerodynamic properties of a building can accentuate the movement and cause motion sickness  in people.

Isha trying out the Interactive Hallway

On our way to the TMD’s interior viewing platform, we were entertained by a dimly-lit interactive hallway where clouds cleared as we stepped on them, revealing a satellite top view of Taipei City. Once inside the platform, we espied the much hyped up, sphere-shaped mass block/wind vibration damper  suspended from the 92nd floor to the 87th floor by 8 steel cables.  Measuring 42 m. in length and 9 cm. in width, each cable is comprised of over 2,000 smaller cables to ensure flexibility and durability. A tuning frame supports the suspended steel cables, monitoring building vibration and adjusting cable movement to regularize building movement and optimize damping. The TMD cuts building vibration by up to 40% and can, on occasion, move by as much as 35 cm., moving with the building at the rate of one oscillation every 7 secs..

The Tuned Mass Damper

Taipei 101’s TMD, the largest, heaviest and only publicly visible damper sphere in the world, consists of 41 circular steel plates, each with a height of 125 mm. (4.92 in.) being welded together to form a 5.5 m. (18 ft.) diameter sphere.  It has a gross weight of 660 metric tons (728 short tons). The TMD was designed, manufactured and constructed by Motioneering, Inc. (Canada), at a cost of NT$132 million (US$4 million), while Thornton-Tomasetti Engineers along with Evergreen Consulting Engineering, Inc. were responsible for the overall structural design.The pinnacle, at 450-508 m. in height, features 2 smaller TMD units of 6 tons  (7 short tons) apiece. The pinnacle may oscillate up to 180,000 times a year due to strong wind loads.

Again posing with another Damper Baby mascot

Beneath the TMD, a specially designed bumper system of 8 primary hydraulic viscous dampers automatically absorbs  and dissipates vibration impacts, particularly during major typhoons or earthquakes where movement may exceed 150 cm. The TMD’s movements are not always visible.
