    Plaza Towers Renovation

    Erhardt Construction engaged in the renovation of the 33-story Plaza Towers, which consists of luxury condominiums, apartments and a 207-room Marriott Hotel. The project included replacement of the entire exterior fa├žade of the building with precast concrete and new windows, extensive re-work of the cooling and ventilating systems, as well as making the structure more efficient and functional. Considerable effort went into budgeting and analyzing various options to optimize the best value for the owner on this unique project.
