Mold Remediation Project – Scope of Work

Scope of Work (SOW) Big Hole National Battlefield

16425 HWY 43 West Wisdom Montana 59761

1. Project Title Mold Remediation Services – Housing Unit #202B, Big Hole National Battlefield, Wisdom, Montana (FMSS Location 31491)

2. Background Big Hole National Battlefield has identified mold growth and conditions conducive to mold development within Housing Unit #202B (FMSS Location 31491) in Wisdom, Montana. The affected area is approximately 75 square feet. The mold is suspected to be associated with moisture intrusion, elevated humidity, and/or ventilation deficiencies within the housing unit.

This project is intended to remediate existing mold contamination, remove affected building materials as necessary, and reduce the likelihood of future mold growth to protect occupant health and preserve government housing assets.

3. Objectives

• Safely remove and remediate mold-impacted materials in accordance with federal, state, and industry standards.

• Protect occupants, workers, and the environment during remediation activities.

• Restore affected areas to a clean, dry, and serviceable condition.

• Identify and report contributing moisture sources.

4. Scope of Work Requirements

4.1 Pre-Remediation Activities

• Conduct a site visit to verify conditions.

• Review any existing mold assessment or indoor air quality reports (if available).

• Develop a site-specific Mold Remediation Work Plan and Health and Safety Plan

(HASP).

• Establish containment areas using appropriate engineering controls (e.g., critical barriers, negative air pressure).

4.2 Mold Remediation

• Remove and dispose of mold-contaminated porous materials (e.g., drywall, insulation, trim) as required.

• Clean and treat non-porous and semi-porous surfaces using HEPA vacuuming and approved antimicrobial agents.

• Operate negative air machines with HEPA filtration during remediation.

• Maintain proper moisture control and drying of affected areas.

• Replace removed materials to match existing construction, including installation of new drywall, tape and texture, priming, and painting to match adjacent finishes.

4.3 Protection and Controls

• Isolate work areas to prevent cross-contamination.

• Use personal protective equipment (PPE) appropriate to the level of contamination.

• Protect adjacent finishes, equipment, and building occupants.

4.4 Waste Handling and Disposal

• Bag, label, and dispose of contaminated materials in accordance with local, state, and federal regulations.

• Maintain clean egress pathways from containment areas.

4.5 Post-Remediation Activities

• Perform detailed cleaning of work areas.

• Conduct visual inspection to confirm removal of visible mold and debris.

• Support post-remediation verification or clearance testing (by others, if required).

• Remove containment and demobilize equipment.

5. Deliverables

• Site-specific Mold Remediation Work Plan

• Health and Safety Plan (HASP)

• Daily activity logs

• Waste disposal documentation

• Final completion report summarizing work performed

6. Schedule The contractor shall complete all work within 60 calendar days from Notice to Proceed. The housing unit is currently vacant, allowing the contractor flexibility in scheduling activities within the performance period.
