Advant ages o f Precas t :

• Wall panels are constructed off-site regardless of weatherconditions ard are rapidly assembled on site.

• As a result projects are completed sooner, leading to earlieroccupancy and faster revenue returns.

• Precast concrete has unsurpassed fire ratings, readilyachieving up to 4 hours fire resistance.

• Concrete will not burn or give off lethal fumes, and will retainits structural integrity for safe evacuation and fire fighting.

• In real fire situations, in temperatures above 1100°C,

concrete has retained its structural stability even in completeburn out situations.

• Because it is impervious to wet and dry rot, the structure willnot weaken over time.

• The density of the concrete provides excellent soundattenuation, thus reducing sound transmission.

• Wall Panels reduce vibration and have fewer joints through

which sound can potentially travel.

• Lower maintenance costs and insurance premiums, togetherwith greater occupant satisfaction and re-sale value.
