The Battery Maritime Building is a ferry terminal in Manhattan, New York, that was originally completed in 1909. It is a historic landmark in downtown New York City and contains a Grand Ballroom, office space and three ferry slips.
The building recently underwent significant renovation, including the addition of four floors. The additional floors, being for hotel and restaurant use, triggered the building to be considered a high-rise structure. There were many unique historical structural elements in the building that were required to remain exposed, therefore contradicting the fire-resistance requirements of the building code.
Holmes Fire undertook fire and structural modelling of multiple conditions throughout the building to demonstrate the exposed construction maintained an acceptable level of fire safety from exposure to realistic fire. This work not only saved significant construction time and cost, most importantly it also maintained the significant historic features of the building.
