Project Scope
- The cleaning and preparation of concrete surfaces including abutments, crossheads and piers
- Identification and repair of concrete spalls to crossheads
- Installation of CFRP strengthening system using carbon fibre fabric
- Application of an anti-carbonation coating to abutments, crossheads and piers
- Installation of laminate and rods to 8 crossheads
Challenges
- Extreme weather conditions caused continual moisture seeping through the roadway from above the structure
- Works were to be completed with minimal disruption to local residents by maintaining access for the duration of the project
- Identified a flaw in the design that required a collaborative solution
Achievements
- Despite extreme weather conditions, the project remained on schedule
- Managed to control and redirect the flow of water to enable drying of crossheads to proceed with works
- Bridge remained open with no disruptions to traffic or pedestrians
- Worked collaboratively with the client to create an alternative design that achieved the desired outcome
- The scaffold system was customised to allow access to areas requiring strengthening
