(CMR).

The procedures detailed in this specification are intended to be used for mold remediation projects in buildings occupied by the general population. This specification section may be a starting point for a project specification covering the requirements for removal of mold contaminated materials in facilities where sensitive populations will re-occupy the facility after remediation. Designer/Specifier will consult with the customer to determine if sensitive populations are present in the facility.

Sensitive populations as used here include those with health deficiencies such as people with immune deficiencies. Facilities where they are found include hospital wings and medical clinics.

SECTION 02 85 00 Page 5

Children in day care centers or senior citizens in nursing homes are also examples of sensitive populations.

For application to such sensitive facilities, the requirements for clearance and verification of removal of mold contaminated materials must meet the more stringent sampling requirements of Appendix B.

Prior to completing these specifications for facilities with sensitive populations, designer/specifier should consult with doctors, infection control, and risk management staff, Government Industrial Hygienist and Occupational, and Environmental Medicine Physician from the supporting Military Treatment Facility (MTF) familiar with or responsible for operation of the facilities.

Information regarding the types of mold found growing in the spaces may be used by the medical staff to determine the level of risk of the population, and help determine the requirements for verification of the remediation project.

Review and repair, if necessary, of HVAC and Building Envelope systems to prevent moisture incursions which could create conditions suitable for future mold growth must be included as part of any mold remediation project, but are not included as part of this specification.

The following information shall be shown on the project drawings:

The project drawings shall clearly show the location and extent of mold contamination and the materials to be removed.

NOTE: The Designer should include unit price items to address mold remediation. Include unit price items for removal and cleaning (e.g., drywall removal, ceiling tile removal, carpet removal, non-porous surface cleaning, semi-porous surface cleaning). Estimate the quantity and specify as unit price items in Section 00 21 13, INSTRUCTIONS TO BIDDERS or Section 01 20 00 Price and Payment Procedures per standard practice of the activity preparing the contract.

NOTE: The work may involve a historic property.

The designer must coordinate review of the proposed work with the appropriate cultural resources manager (CRM) and cultural resource laws and regulations, as part of the environmental review and permitting

SECTION 02 85 00 Page 6 process. Consultation with stakeholders, including the state historic preservation office, may be required, and work involving historic properties will likely be required to confirm to the Secretary of the Interior's Standards for the Treatment of Historic Properties (usually at the REHABILITATION level).
