Demolition & Investigation Phase Objective: Determine extent of lintel corrosion and prepare for full structural remediation. • Carefully remove brick masonry above all three steel arched lintels (north, center, and south arches). • Inspect and document the condition of the steel lintels to determine: o Level of corrosion o Section loss o Structural integrity • Structural engineer to make a final determination if each lintel must be: o Fully replaced, or o Cleaned, treated with protective coating, and reused G. Structural and Masonry Repairs Objective: Restore structural integrity, waterproofing, and aesthetics of the west entrance wall. Wall Reconstruction • Reconstruct masonry wall section above each lintel using: o Matching brick veneer for exterior finish o Appropriate structural backing (brick/block) to match existing wall composition • Integrate new flashing and water-resistive barriers, to be accepted by a qualified architect, ensuring long-term water management and durability. Precast Elements • Remove and replace damaged precast signage and MSP emblem with new elements matching the original design and dimensions. • Replace damaged precast capstones along parapet as needed. • Ensure proper jointing and sealing of capstones with modern waterproof mortar or flexible sealant to prevent future water infiltration.
