Precast Veneer Replaced By All-Precast Structure

Abstract:

Utilizing engineering solutions to architectural problems greatly enhanced the architectural appearance of this building. Long-span prestressed, light weight concrete beams, post-tensioned to concrete columns, became the architectural facade of the building. Control of the beam deflection and camber was one of the major design considerations. The central core of the building was constructed of hardrock concrete walls for fire rating and structural considerations. The walls were constructed with the slipform construction technique, which aided the construction schedule by allowing the core to be completed before steel or concrete was delivered to the project site. Since the structural system was unique and it was necessary to control cost, the precast concrete was bid before the rest of the trade in order to determine this major cost item before proceeding.
