Marriott Courtyard, Ocoee, Florida. The construction of this project has three phases. The first phase was a renovation of the existing roof to add a new mansard type overbuilt roof. The second phase was the demolition of an existing wing including new support framing for the remaining walkway. The final phase is a new 80-unit hotel with 47,000 SF. The structural floor system is 8″ hollow core planks with 8″ masonry bearing walls and structural steel transfer beams at the second level and roof support beams.
