MDM Development has been granted approval from the FAA to build the 54-story Marriott Marquis Miami Worldcenter Hotel & Expo Center.
The agency approved the developer’s request to build at a height of 640 feet above ground level, or 653 feet above sea level. It took nine months to review the proposal, which was submitted in December 2014, and the approval will expire in February 2017 if construction doesn’t begin by then.
Along with 1,800 rooms, the project will also include 600,000 square feet of convention space. Total cost is estimated at $750 million.
Construction is expected to begin by this fall and take up to 36 months to complete. Coastal Construction is the contractor.
Also approved this week was HES Group’s Triptych project in Midtown Miami at 330 feet above ground. When completed, it will include a 40,000 square foot retail center on the lower floors, topped by 290 hotel rooms and 31,000 square feet of office space.
