Buildings commonly need to serve several purposes; a single structure can house retail space, parking facilities, office and residential units. A precast concrete building system provides noise and vibration isolation, fire separation and resistance, penetration flexibility, and structural support for small spaces above large open areas.
Vertical construction, in which shallow floor depths combine with open floor plans, can take advantage of precast's long spans, fast erection, and all-year construction. Specialized beams of precast concrete or steel create shallow floor systems supported on precast columns. The lightweight nature of the product allows erection by tower crane, decreasing site congestion. Precast concrete's fire-resistance makes it an excellent material for tower construction by reducing the spread of fire, smoke, and noise between rooms and floors. Precast balconies can be integral components in the load bearing system.
