Steady Flexible Prefabricated Concrete Segmental Forms , Concrete Metal Formwork

The bridge viaduct is divided into small segments, that are prefabricated in the good quality control casting yard, then, delivered to install by good erection equipment.

Advantages and Benefits

1. Construction Simplicity
• easier installation of external post-tensioned tendons

2. Time Savings/Cost Effectiveness
• precast segment to be prefabricated and stored at casting yard while foundation and sub-structure are being built.
• by using efficient erection method and equipment, the rapid installation of viaduct can be achieved.

3. Quality Control Q - A/QC
• precast segment to be produced in factory-manner condition w/ good quality control.
• minimum interruption natural impacts such as bad weather, rain.
• minimum waste of material
• good precision in production
4. Inspection and Maintenance
• external prestressing tendons can be easily inspected and repaired if required.
• maintenance program can be scheduled.
