  - This paper details the monitoring and repair of an impact damaged prestressedconcrete bridge. The repair was required following an impact from a low-loader carryingan excavator while passing underneath the bridge. The repair was carried out bypreloading the bridge in the vicinity of the damage to relieve some prestressing. Thispreload was removed following the hardening and considerable strength gain of the repairmaterial. The true behaviour of damaged prestressed concrete bridges during repair isdifficult to estimate theoretically due to lack of benchmarking and inadequacy ofassumed damage models. A network of strain gauges at locations of interest was thusinstalled during the entire period of repair. Effects of various activities were qualitativelyand quantitatively observed. The interaction and rapid, model-free calibration of damagedand undamaged beams, including identification of damaged gauges were also probed.This full scale experiment is expected to be of interest and benefit to the practisingengineer and the researcher alike.
