WGI has completed Phase 1 of the project, providing a condition assessment of the structure with estimated repair costs. The concrete members exhibited widespread deterioration throughout the structure resulting primarily from corrosion of the embedded reinforcing steel. Overall, approximately 15% of the concrete slabs at the P1 and Executive Levels have deteriorated.
Repairs, which will be phased over three years to accommodate the owner’s budget, include:
- Rout and seal all slab cracks and joints to prevent moisture infiltration.
- Inject leaking wall cracks with a urethane grout.
- Replace corroded and cracked drains and piping.
- Replace cracked and deteriorated concrete wheel stops.
- Replace corroded or missing pipe hangers.
- Repair, clean, and coat corroded steel framing around the overhead doors.
- Install new pavement markings following the installation of the deck coating system.
Project Highlights:
- Post-tensioning Repairs
- Concrete Repairs
- New Deck Coating System
- Phased Repair Program v
