GeoMetrix is frequently retained by the Canadian National Railway for the concrete rehabilitation of various bridges in Western Canada. Rehabilitation scope typically includes: 1) Review of CN’s concrete inspection reports and photos for identification of rehabilitation items 2) Detailing and design of reinforcement for concrete repair, and 3) Providing detailed concrete repair drawings and bar list.
GeoMetrix also provides detailed construction procedures to consider key periods where train traffic may not be permitted during the repair work and to consider proper preparation, reinforcement installation, and curing conditions for concrete repair.
