Construction is fast with prestressed concrete. As the beams are factory produced,
site preparations can proceed. Prestressed concrete is ideal for limited access
locations and where speed of erection is crucial.
Not weather dependent
Prestressed concrete bridges are for all seasons: they can be produced and installed
at any time of the year, regardless of climate.
Familiar material
Prestressed concrete is a familiar material for construction companies and requires
no special bracing and shoring during erection.
Deck maintenance and replacement work can be done while the bridge is in partial
service.
Assured plant quality
Plant-cast prestressed concrete products are inspected and quality controlled at
the processing plant. In fact, each operation in the manufacturing process, from
concrete production to curing, is controlled and inspected in accordance with rigid
standards. Tolerances for dimensions, tensioning procedures, material properties,
and other critical details are controlled according to well established and rigid
standards.
Minimal traffic interruption
Because of the availability of plant-produced sections, prestressed concrete bridges
can minimize the public's inconvenience and improve its safety, because prestressed
concrete bridges can be opened rapidly.
Construction is fast and easy and can be accomplished by a wide range of construction
companies -- they will be working with very familiar materials.
