Investigation and field testing to determine the causes of water leakage of the law library facade's tiered cascade curtain wall with slope glazing. Internal concealed spaces within the curtain wall system permitted water which penetrated the exterior transferring many stories before entering the interior and causing damage. Trial repairs were developed, implemented, and retested to demonstrate effectiveness. Based on the program, repair plans which included provisions for the Owner's desire to undertake the remedial work in phases were used.
