Specifications include, but are not limited to: Cast Stone 1. Remove and restore cast stone masonry at the sixteen steel-framed window units on the east (Main Street) elevation of the building and the horizontal cornice band that extends the full length of the building above the window heads. This includes the decorative cast stone units at the perimeter of the window openings as well as the cast stone units at the spandrel panel within the window opening. Previous painted wood infill patches should be removed and replaced with cast stone as well. Upon removal, cast stone units should be evaluated and depending upon their condition, salvaged for reinstallation or replaced. Salvaged units should be cleaned, repaired, and prepared for reinstallation. Replacement units should match the existing cast stone units in color, material, and profile. Coordinate repairs with steel lintel and steel-framed window repairs. 2. Repair cracked and spalled cast stone units at the main theater marquee elevation. Remove previous repairs where applied to evaluate the existing conditions. Perform repairs to cast stone units with spalls greater than 3 inches square and cracks greater than 1/16 inch wide. 3. Repair or replace all sixteen steel lintels above the window openings as well as shelf angles spanning between window heads at the cast stone cornice band. Clean existing built-up steel lintels of surface corrosion and evaluate. Where structurally intact, existing built-up steel lintels can be primed and painted. Install stainless steel drip edge and membrane flashing with end dams secured to backup masonry with termination bar. Where severely deteriorated, the built-up lintel should be replaced with new hot-dipped galvanized lintels and then flashings installed. 4. Clean the cast stone along the main street elevation with a one-part biocide or mild detergent. B. Brick Masonry 5. Repoint localized areas as indicated on Drawings and confirmed by A/E of the concrete brick and the glazed brick where joints are open or deteriorated. 6. Repair individual concrete brick units indicated in the field by the A/E at the alley and penthouse for the fly space penthouse and auditorium. Repairs will include removal and replacement of individual spalled and cracked brick. 7. Replace backer rod and sealant at existing control joints cut into the concrete brick at the alley elevation and fly space and auditorium walls. This will include removal of existing sealant if present and replacement with new backer rod and sealant. At locations where vertical cracking is present through mortar joints and brick units, new control joints will be cut into the brick to follow the line of cracking and fill with backer rod and sealant
