The Landlord was creating the openings in the slab for the LED screen, escalators, elevator, and floor layout, based on our drawings. Due to the large areas of floors, columns, and girders being proposed to be removed, it was determined that this much removal would leave the structural integrity of the building at risk, so it needed to be evaluated and modeled by an engineer. We hired the Landlord’s structural engineer to model the building’s structure and design for new steel in order to ensure stability.
