Bridge Design Manual Whats New?

Waters of the United States Placement of fill material below Ordinary High Water Mark (OHWM) requires 401/404 permit Preliminary Site Plan: Plan area of fill footprint Volume of fill below OHWM BDM Fig. 208 & 209

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

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

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

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

2005 C&MS Web version available Hard copies available at Office of Contracts in May 2005 Use for all projects filed April 4, 2005 and later Use for all projects sold August 10, 2005 and later

2005 C&MS Item 512 – Treating Concrete Concrete Sealing (SS 864) HMWM (SS846) SRS (SS 841) Gravity-Fed Resin (PN 515) Epoxy Injection (PN 522)

2005 C&MS Item – Approval of Construction Plans One P.E. Stamp for plans with railroad involvement Two P.E. Stamps for: Sheeting & Bracing Demolition over traffic Falsework Plans Erection Plans Jacking & temp. support Construction stresses Temporary Structures Affects Notes In BDM Section 603

Stage 2 Review Submission Requirements Bridge Plans Complete General Notes Details show dimensions, bar marks & spacings Retaining Wall Plans Noise Barrier Plans Special Provisions Load Rating Report Major & Minor PDP only

Stage 3 Review Submission Requirements Stage 2 Plans in compliance with review comments Estimated Quantities Reinforcing Schedule Estimated Quantity Calculations Load Rating Report Minimal PDP only

Coming Soon… Fatigue Policy Fatigue Analysis for welded cover plate retrofit: Less Subjective Other Fatigue Details included Truck Volume Retrofit?HighYes Medium Analysis Required LowNo

Coming Soon… Stay-in-place metal forms Limited use basis Project specific examples: Environmental or site restrictions Faster bridges

Coming Soon… Life Cycle Cost Analysis Additional guidance for: When to use Interest rates Life expectancy

Coming Soon… LD-4 Estimating Form Provide estimated quantities for MSE Walls: Wall incidentals (e.g. cast-in- place concrete, select granular fill, unclassified excavation, etc.) Concrete coping incidentals (e.g. concrete, reinforcing steel, sealer, etc.)

Coming Soon… LRFD Developing ODOT Commentary to LRFD Pilot Projects Training Courses & Seminars Concrete Superstructures Steel Superstructures Substructures July 1, 2007!!

Coming Soon… Bridge Information Requests Web based information request Includes: Specialized bearings Modular joints Alternate coating systems Retired Standard Drawings
