Work crews have started work in downtown Miami on the biggest construction project in the city’s history, which is also America’s second largest mixed-use urban development. Construction crews began drilling 400, 150 ft. deep steel structural support piles into the ground in February. Next they will lay the foundation for Miami Worldcenter – the city’s new retail, residential, entertainment and transportation complex.

Phase one construction focuses on Paramount Miami WorldCenter. It is the project’s 700 ft., 60-storey, $500 million signature residential skyscraper. It will feature the world’s largest private urban amenities deck with resort style pools, bungalows, walking paths, gardens, tennis courts and a regulation soccer field.

“You are literally going to see six blocks being developed all at the same time,” Daniel Kodsi, Paramount Miami WorldCenter CEO and master developer, said in a news release. “This is basically step one of multiple steps in which you are going to see six buildings going vertical.”

Kodsi says that Miami WorldCenter will intertwine Paramount with six other residential and office buildings, an 1,800 room Marriott Marquis and convention center; the intermodal hub for the downtown MetroMover and Metrorail elevated transit systems; the adjacent main terminal for the under construction All Aboard Florida high speed railroad; and the Miami WorldCenter retail and restaurant promenade.

It will feature an unprecedented collection of retail stores and a fusion of restaurants. The 27-acre Miami WorldCenter will be second in size only to New York’s Hudson Yards development at 28-acres. In comparison, New York’s Rockefeller Center is 22-acres.
