14 PROCEDURES FOR DEVELOPMENT OF REPAIR PLANS EXAMPLE: DESIGN OF TRUSS VERTICAL MEMBER REPAIR Identify the repair locations through inspection and coordination with DOTD Truss Member forces are obtained through truss analysis Develop repair scheme: o For members with dominating dead load the dead load stress should be minimize thru jacking or posttension before new steel for repair is integrated into the member o For members with significant live loads live loads need to be restricted during the repair Repairs are grouped into a Type based upon similar repair details Each repair type is then assigned a Non-standard (NS) item number and given a unique item name for bidding purposes Example: TEMPORARY JACKING SCHEMATIC FOR VERTICAL REPAIRS TYPE I, II, III-A AND III-B SUMMARY OF ESTIMATED QUANTITIES ITEM NO. ITEM UNIT QUANTITY NS NS BRIDGE SUPERSTRUCTURE REPAIR (TRUSS VERTICAL MEMBER REPAIR, TYPE I) EACH 9 NS NS BRIDGE SUPERSTRUCTURE REPAIR (TRUSS VERTICAL MEMBER REPAIR, TYPE II) EACH 1

15 PROCEDURES FOR DEVELOPMENT OF REPAIR PLANS Key Plan of Repair Locations Details for Each Repair Location Temporary Jacking Scheme Notes to Clarify Intent of Repairs

16 PROCEDURES FOR DEVELOPMENT OF REPAIR PLANS Temporary Post- Tension scheme

17 NON-STANDARD (NS) ITEMS Phase 1: 127 Non-standard Items Used for Needed Repairs Phase 2: 57 Non-standard Items Used for Needed Repairs Pay Unit = Each Total Number of Repairs = 4175 (2480 Phase 1,1695 Phase - 2) Reasoning/Benefits - Provides a unit bid price for each repair type - Provides a unit price for additional similar repairs found during construction Bridge Superstructure/Substructure Non-standard Item includes all labor, equipment, materials, and incidentals required to complete the work. 17
