Attachment 4 - Buildind D Basement D-025 Before injection.pdf

These images document water damage and deterioration in a basement space, specifically Building D, Room D-025, which appears to be part of a federal contract opportunity (Solicitation Number 040ADV-25-Q-0010) for addressing water leaks. The photographs show:

1. A concrete wall with extensive water damage, characterized by crumbling plaster, peeling paint, and moisture-induced structural degradation. The wall shows green and yellow discoloration indicative of moisture and potential mold growth.

2. Blue-framed storage racks or shelving units with wooden platforms, positioned in the damaged basement area. The space is marked with location identifier "B-A30" and shows signs of significant environmental stress, including water infiltration and wall deterioration.

The images serve as visual documentation supporting the federal contract opportunity for non-destructive testing and repair services to address water leakage in this specific basement location, requiring comprehensive investigation and corrective interventions.
