5 Prestressed Beam Camber Plans shall include: Camber @ release: (B-C) Camber @ erection: (1.8B-1.85C) Long term Camber: (2.45B-2.40C)

6 Load Rating Entire Section 900 Revised to address: Buried vs. Non-buried Bridges Major, Minor & Minimal PDP Design-Build Value Engineering Change Proposals Rating requirements: PC-Bars for standard bridge types Minimum Design Loading

7 Multi-Span Prestressed Beams Two Loading Conditions: Simple-span for non- composite loads and continuous for live load and composite dead load HS-25 FWS Simple-span for all loading conditions HS-25 No FWS

8 MSE Walls Plan Preparation Traditional Method eliminated Three-Line Diagram Method Special Provisions New pay items Square Ft. vs. Lump Sum Undercut & Backfill Concrete Coping
