Innovative and productive method forbridge construction across waterway(Extensive precast system)
Typical conventional methodfor bridge construction acrosswaterway (On-site casting)
Advantages of using precast elements• Reduces need for dangerous work at height• Time-consuming erection of temporary scaffolding is also reduced• Less risk of concrete spillageinto river
