The Construction process was organized in different phases as outlined in the following:
- Replica Structures for assessment of materials and methods
- Temporary structures
- Removal of detached concrete
- Removal of part interventions
- Sandblasting and surface preparation
- Electrochemical chloride extraction and re-alkalization
- Patch repair
- Epoxy injection
- Temporary Supporting Structure
- Reinstatement of reinforcement
- Reinstatement of Concrete
- Application of UHDC (Jacketing to column)
- Application of TRC (Shell elements)
- Application of Sensors Embedded in the structure (Durability & Structural health Sensors)
- Application of Sensors applied to UHDC and TRC. (Durability & Structural health Sensors)
