Significant reduction in the amount of concrete
reinforcing steel required.
Thinner structural members as compared to
concrete, resulting in lower overall building heights and reduced
Aesthetically pleasing structures that harness
benefits of cast-in-place structures with curved geometries, longer
and slender members with large spaces between supports.
Superior structural integrity as compared to
concrete construction because of continuous framing and tendon
Monolithic connections between slabs, beams,
that can eliminate troublesome joints between elements that require
Profiled tendons that result in balanced

Better crack control, which results from
compressive forces applied to the structure during prestressing.
Reduction in overall building mass, which is

As compared to steel, non-prestressed concrete
precast construction offer faster floor construction cycles, lower
weight, lower floor-to-floor height, larger spans between columns and

post-tensioned elements, minimum congestion of prestressed and
reinforcement, and earlier stripping of formwork after tendon stressing.
