DocuSi n Envelope ID: B94F2D40-3B3C-47A7-86C2-6F1 B4F92C62C E tnvironmeniai 3omuons uroup Leading people,companies and communities to live, Report with Protocols for Re m e d i a t i o n work and prosper in a sustainable environment. PHASE I: DEMOLITION NOTE:Any moisture issues identified in this report or uncovered during the remediation must be confirmed as having been repaired prior to the replacement of building materials. Work Area (drywall around windows/exterior doorways throughout the building.And the lower exterior facing walls of the command room,the EOC, room 116, room 119,and room 123): • As mentioned above, establish negative pressure of the work zone prior to beginning work and position air scrubbers where they can move the most air. • Remove any items possible from the building to a location off-site. • Place all removed building materials in the sealed plastic bags prior to removal to the outdoors for disposal. • Contact ESG if hidden moisture damage or fungal contamination is observed or if you are unsure how any hidden contamination should be addressed. • Significantly moisture damaged or fungal damaged building materials should be removed.This includes the drywall around the windows, and the lower exterior facing drywall (potentially up to three feet) in the command room,the EOC, room 116, room 119, and room 123, and any other porous or semi porous (non-structurally significant) building materials at the wall framing systems. o In order to fully inspect the wall framing systems and determine the full extent of the moisture issues, removal of additional drywall may be necessary. It is possible that the scope of drywall removal at the lower portions of the exterior facing walls on the main level may need to be increased based on findings during demolition. • Moisture stained ceiling tiles in the EOC should be removed and the moisture issue should be addressed. • Structural materials that are significantly contaminated but cannot be removed (such as wall framing) must be thoroughly cleaned with an anti-microbial chemical and then HEPA-vacuumed as indicated below. Structural materials with visible fungal growth may be encapsulated with anti-microbial paint after the clearance test is complete. o Most of the wall framing system will be remediated from the interior access, however exterior portions will likely also need to be removed to allow access to the entire wall framing system. PHASE II: CLEANING Work Area (entire entire of building): Note: the warehouse will require some cleaning, however the air samples in the warehouse showed 'warehouse like conditions'with moderate/high amounts of the fungal spores which were present at greater amounts outdoors. The main approach for the warehouse should be to determine which storage items should be stored in a conditioned and controlled setting(conditions with moisture levels below 60%and contained from high amounts of outdoor fungal spores). The items that need to be stored in a conditioned setting should be cleaned before being moved to the new location or air tight storage container. • After all demolition has been completed and remaining building materials measure<20% moisture content, convert the negative air machines to air scrubber function.
