In order to evaluate the extent of the structural damage and to establish repair budget estimates, SK&A performed a comprehensive sounding survey of the suspended decks to locate any latent delaminated concrete resulting from the corrosion of reinforcing steel.  Realistic repair boundaries were marked on the decks in accordance with the International Concrete Repair Institute Guidelines.  The repair sizes and locations of the top surfaces and soffits (underside) of the suspended garage decks, as well as observed deficiencies were also plotted on plan view drawings.  Other deficiencies noted during SK&A’s assessment of the facility included top surface as well as soffit concrete deterioration, corroded tendons and joint sealants, deteriorated traffic coating, a deficient stairwell, and cracked PT beams.
