Miami-based MDM Development Group has topped off construction of its 47-story Met 2 Financial Center office tower, saying that the building will be completed by April 2010. The 750,000-square-foot skyscraper is one of two towers in a joint venture project by MDM Development and New York insurer MetLife. The other tower is a 42-story hotel building that houses both a Marriott Marquis and a Hotel Beaux Arts. Tim Weller, MDM Development vice president, said the glass exterior, including impact-resistant windows designed to withstand Category 5 hurricane winds, should be finished by December. Tenants include law firm Greenberg Traurig, Deloitte and Business Centers International.
