Abstract

In this session we will present a case study of two SR 7 bridge projects, both of which suffered failures during the design phase that required emergency temporary repairs. Each project includes good examples of innovative cost savings found by implementing practical design methods, including reusing beams from emergency repair, widening a structure to eliminate a run-around bridge, changing beam types, re-use of existing footings, and shoulder width reduction. Emergency repairs required schedule adjustments and flexible design to incorporate repairs to minimize rework.

SR 7 Emergency Bridge Repairs During Design

STEW279

In this session we will present a case study of two SR 7 bridge projects, both of which suffered failures during the design phase that required emergency temporary repairs. Each project includes good examples of innovative cost savings found by implementing practical design methods, including reusing beams from emergency repair, widening a structure to eliminate a run-around bridge, changing beam types, re-use of existing footings, and shoulder width reduction. Emergency repairs required schedule adjustments and flexible design to incorporate repairs to minimize rework.
