  • Fairytale of New York: Hudson Yards
    September 29th, 2017 Fairytale of New York: Hudson Yards At three times the size of the Rockefeller Center, when it is fully built out, some time around 2040, more than 27m sq ft of new class-A office space, 20m sq ft of new housing, 3m sq ft of hotels and 2m sq ft of retail will have been delivered by developers that include Related Companies, Oxford Properties, Brookfield and Tishman Speyer. Millions of square feet of space have already been completed and leased to blue-chip occupiers, and further significant deals are rumoured to be on the cards. No wonder the Hudson Yards district is one of the hottest property markets in New York City at the moment. So how did a development of this scale and ambition come about, who is doing what in the district and where is Hudson Yards’ new office occupier base being drawn from? Historically the Hudson Yards district consisted of warehousing and industrial space alongside the Manhattan waterfront. The area primarily acted as a rail hub that was fed 747 Third Avenue, Floor 18 New York, NY 10017 212.889.0808 [email protected] marinopr.com by the High Line - which closed years ago and has over the past decade been converted into green public spaces - as well as the Long Island Rail Road. But that all started to change when New York mayor Michael Bloomberg came to power in the early 2000s. “He noted that the average age of commercial office property in Manhattan was north of 75 years and with that in mind, he said, quite correctly, if we’re going to attract the best and brightest in the TAMI [technology, advertising, media and information] sectors, we’ve got to have some new product,” says Bruce Mosler, chairman of global brokerage at Cushman & Wakefield.

  • Burj Al Arab: the Only 7-Star Hotel in the World
    TRAVEL Burj Al Arab: The only 7-Star Hotel in the World by Engr. Chin Mee Poon, FIEM, P. Eng. ON our way back from Scotland, my wife and I stopped over at Dubai for three nights to see how much the place has progressed since our last visit in 2002. Dubai is a tiny emirate situated near the tip of a promontory of the Arabic Peninsula that separates the Persian Gulf from the Gulf of Oman. It is the second largest of the seven emirates that make up the United Arab Emirates, one of the richest Arabic countries. Before oil was discovered in the 1960s, Dubai was poor and its people lived a nomadic life in a desert environment. In less than half a century, the desert land on both sides of Another first is, of course, the well-known Burj Al Arab, the Dubai Creek has been transformed into a large oasis of often touted as the world’s only 7-star hotel. Built on an concrete jungle, and this oasis is still expanding with more artificial island in the vicinity of the luxurious 5-star Jumeirah giant structures shooting up to scrap the sky. Beach Hotel, this all-suite hotel is in the shape of a sail. It is estimated that 20% of the world’s tower cranes are At 321m, it is also the tallest hotel in the world. And with currently employed in Dubai. Of its population of about its cheapest suite going for about Dh3,500 (about RM3,500) a 1.5 million people, almost 80% are foreign workers from night, it is definitely the most expensive hotel in the world.

Excitations can be caused by wind forces, pedestrian traffic, machinery or earthquakes. Natural frequencies and damping are typically low for these structures. With GERB tuned mass dampers (TMD), these vibrations can be easily reduced. All GERB TMDs, both vertical or horizon- tal, have three main components: Spring or pendulum – Oscillating Mass – Viscodamper® (viscous fluid damper). Every TMD is exactly tuned to the main natural frequency of the structure.
