Post-tensioned precast beams allow for longer spans without intermediate piers.
| Metric | Precast Concrete | Cast-in-Place | Steel Girders |
|---|---|---|---|
| Installation Speed | 2-3 days per span | 10-14 days | 5-7 days |
| Weather Dependency | Minimal | High | Moderate |
| Maintenance at 20 Years | Low | Moderate | High |
| Initial Cost | Moderate | Low | High |
What does the data show about cost efficiency?
US road construction companies report 15-20% savings on labor when using precast systems.

How do you implement precast on site?
Step 1: Foundation Preparation
Ensure footings are level within 1/4 inch across the entire span.
Use high-strength grout for bearing pads to accommodate precast tolerances.
Step 2: Girder Installation
Lift precast beams with spreader bars to prevent cracking.
Verify camber measurements match shop drawings before final positioning.
Step 3: Deck Panel Placement
Install precast deck panels with epoxy-coated dowels for shear transfer.
Weld connection plates between adjacent panels per AWS D1.4 standards.
Step 4: Final Connections
Grout all pocket connections with non-shrink material.
Apply rapid-setting concrete overlay to achieve 4-hour traffic readiness.
