The basement level parking deck underwent a major restoration beginning with hydro-demolition to rapidly remove deteriorated concrete with minimal vibration related noise. The entire deck was shored due to the extensive removal. A concrete overlay was placed providing low-shrinkage, impermeable and electrochemically compatible repair. The high cost to the owner of relocating 400 cars necessitated that the project be completed in a tight, 14 week construction schedule.
