As the indoor humidity issue (mostly due to the HVAC units) is resolved,the microbial spores will likely begin to disperse at higher levels. Due to these findings, it is important the humidity issues at the HVAC cassettes be addressed to ensure that the overall microbial growth issue does not become any worse. It is equally as important that a professional remediation plan is put into place order to help prevent any additional microbial contamination, and to clean and remediate the interior of the building.The moisture infiltration issues at the windows and main level lower walls should be additionally investigated while the wet drywall is removed, and the moisture issues should be repaired as needed. The remediation recommendations are outlined below. Due to the amount of demolition and cleaning recommended, ESG recommends that the occupants consider moving to a temporary location to prevent potential adverse health reactions, and to allow for a thorough, efficient, and effective remediation. It is likely that hidden moisture damage and microbial contamination exists in portions of all of the exterior facing walls where the weep holes were level with the ground. The remediation process will therefore include some'discovery' that could have an impact on the scope of work.Therefore, rigorous professional remedial actions per the IICRC S520 Standard to remove the microbial hazards, protect the occupants and a high level of care to protect remediation personnel are very important. The protocols indicated below are designed to address the fungal hazard issues indicated above and the findings of our investigation. The remediation contractor is not expected to remove all fungal spores from the building and contents, however, remediation is performed to minimize risk to occupants and building materials that can be compromised by fungal activity by restoring the building to normal fungal ecology as defined by the IICRC. The protocols are established in accordance with the policies established by document 5520 published by the IICRC. The 5520 currently sets the only standard for mold remediation. IICRC 5520 Condition 3 (moisture impact zones—Entire interior of the building):water-damage and microbial growth, including visible, settled and hidden fungal spores on building materials. • Remediation should be conducted by personnel trained on proper clean-up methods, personal protection, and potential health hazards to comply with requirements of the OSHA Hazard Communication Standard (29 CFR 1910.1200) • Respiratory protection in accordance with the OSHA respiratory protection standard (29 CFR 1910.134) is recommended. Gloves and eye protection should be worn. • Applicable federal, state and local administrative codes, rules and statutes must be identified and followed. • The main work area is defined as the rooms with windows, rooms with HVAC cassettes, and rooms at the main level connected to exterior facing walls.The remediation contractor should coordinate with the HVAC contractor and building exterior specialist to address the moisture issues at the HVAC units, moisture issues at the windows, and moisture issues at some of the lower exterior facing walls. Moisture issues are generally repaired during the beginning of the remediation process. o Note: due to the office section of the building currently being occupied, special planning and precaution will have to take place when determine a remediation plan. It is likely that a large amount of(exterior facing) drywall will need to be removed, and therefore will require working with the occupant to determine the best plan of action.The optimal options for remediation would include temporarily displacing the occupants during the remediation process.
