1. PURPOSE AND BACKGROUND

This Statement of Work (SOW) establishes requirements for licensed mold remediation, selective removal of mold-contaminated materials, HVAC cleaning, temporary humidity control, waste disposal, and post-remediation verification at the Merritt Island National Wildlife Refuge (MINWR) Fire Office.

Reconstruction, permanent repairs, and finish restoration are excluded and will be performed under a separate contract.

Bio Pro: Mold & IAQ Testing inspected the facility on May 22, 2026. The Mold Assessment Report and Remediation Protocol documented localized mold contamination, ongoing moisture intrusion, approximately 70 percent indoor relative humidity, and visible contamination affecting the attic, office wall assemblies, HVAC components, and selected ductwork.

1.1 Known Conditions

• East Office north wall cavity air sample: elevated Aspergillus/Penicillium (1,200 spores/m3) and

Stachybotrys (67 spores/m3).

• West Office wall surface sample: growth likely, including a medium level of Stachybotrys.

• Attic surface sample: growth possible, including low levels of Stachybotrys and Cladosporium.

• Occupied-area and conference-table air samples were not elevated at the time of the assessment;

this does not eliminate localized concealed contamination.

• Visible mold was observed on several air-conditioning registers and on the interior lining of a flex-duct branch serving the conference room.

• Severe water intrusion and damage were observed along the north side of the building, particularly at the East and West Offices and window assemblies.

1.2 Contract Documents

• This SOW, including Appendix A (Assessment Floor Plan and Sampling Summary).

• Attachment - Bio Pro Mold Assessment Report & Remediation Protocol, inspection date May 22, 2026, 28 pages.

• The solicitation, award document, accepted Contractor Work Plan, approved submittals, and written modifications issued by the Contracting Officer.

If a conflict exists, the more stringent health, safety, containment, or cleaning requirement governs unless the Contracting Officer provides written direction. Scope conflicts, omissions, or questions shall be raised before proposal submission.

2. OBJECTIVES

• Remove identified mold-contaminated materials and remediate remaining affected substrates in accordance with IICRC S520 and the assessment protocol.

• Maintain effective containment, negative air, worker protection, and temporary humidity control throughout remediation.

• Obtain independent post-remediation verification before containment removal and turnover for separate reconstruction.

• Protect occupants, workers, Government property, records, equipment, and refuge resources.

• Document moisture intrusion, deterioration, and repair needs encountered during remediation without performing reconstruction or permanent corrective work.

3. SITE VISIT, FIELD VERIFICATION, AND SCOPE BASIS

The Government has not performed a detailed quantity takeoff. The assessment floor plan contains approximate dimensions and identifies known remediation limits. A mandatory pre-proposal site visit is required. Each offeror shall inspect accessible work areas and verify dimensions, quantities, access limitations, staging requirements, equipment connections, and other observable conditions necessary for a complete lump-sum remediation proposal.

The Contractor shall provide all labor, supervision, licenses, materials, equipment, containment, temporary controls, transportation, disposal, testing support, and incidentals necessary to complete the mold-remediation scope. The Contractor shall not include reconstruction, replacement finishes, permanent moisture-source correction, window work, ceiling repair, plumbing repair, roofing work, or permanent HVAC replacement.

Contamination that extends materially beyond the base-scope limits in Section 6 shall be photographed and reported to the COR immediately. The Contractor shall not expand demolition or remediation beyond the defined limits without written authorization from the Contracting Officer. The COR does not have authority to modify the contract.

4. GENERAL REQUIREMENTS

4.1 Occupancy, Access, and Protection

• The building shall remain vacant during intrusive remediation and until successful clearance and

Government authorization for access.

• Before mobilization, coordinate access, work hours, staging, utility outages, waste routes, parking, and protection of refuge operations with the COR. Normal work hours: [CO INSERT].

• Inventory and protect furniture, records, IT equipment, and other contents. Relocate contents as necessary for remediation and place them in a Government-designated clean storage area.

• Provide temporary barriers, floor protection, security, and protection of building components to remain.

• Do not disturb or attempt to repair unsafe ceiling, electrical, plumbing, window, roofing, or structural conditions outside the mold-remediation scope. Secure the immediate area and notify the COR.

4.2 Permits and Specialty Trades

Obtain permits and inspections specifically required for mold remediation, selective demolition, waste handling, or HVAC cleaning unless the solicitation states otherwise. HVAC work shall be performed by personnel holding applicable licenses. Building reconstruction and specialty-trade repairs are excluded.

4.3 Hazardous Materials

Before solicitation, the Government will provide an asbestos inspection report covering materials reasonably anticipated to be disturbed by the Work. The Contractor shall review the report before proposal submission and shall not disturb identified asbestos-containing material unless such abatement is expressly included in the contract. Upon discovery of suspect hazardous material not addressed by the contract documents, the Contractor shall stop affected work, secure the area, and notify the COR.

Additional abatement shall not proceed without written authorization from the Contracting Officer.

4.4 Government-Furnished Utilities

Existing electricity and water may be used at no cost where available and approved by the COR. The Contractor is responsible for distribution, temporary connections, protection, and restoration of affected systems. The Contractor shall not use sanitary, stormwater, or refuge grounds for disposal of remediation waste, chemical residue, or contaminated water.

5. REMEDIATION CONTROLS

5.1 Pre-Work Submittals

6. DETAILED MOLD-REMEDIATION SCOPE

6.1 East and West Office North Walls

• Remove and discard drywall and insulation from floor to ceiling along the entire north wall of both the

East Office and West Office, as shown in Appendix A.

• Remove contaminated base, trim, sealants, air/vapor-control materials, and other porous materials necessary to expose the affected wall cavities. Salvage uncontaminated Government-designated items where practicable.

• At wall returns and adjoining surfaces, continue removal at least 24 inches beyond the last visible staining or mold growth, subject to the out-of-scope procedure in Section 3.

• HEPA vacuum, mechanically clean, antimicrobial damp wipe, and final-HEPA-vacuum exposed framing, sheathing, plates, and other retained materials. Follow product-label dwell times.

• Do not replace framing or other building materials. Photograph and identify wood rot, structural deterioration, active leakage, or materials that cannot be successfully remediated for separate Government action.

6.2 West Office West Wall

• Remove and discard drywall and insulation for the full length of the West Office west wall from the floor to a height of 24 inches.

• Inspect exposed materials and continue removal vertically and laterally at least 24 inches beyond the last visible staining or mold growth, subject to the out-of-scope procedure in Section 3.

• Clean and treat retained materials using the procedure in Section 6.1. Do not reconstruct the wall.

6.3 Attic Remediation

• Establish attic containment and protect openings to occupied spaces below.

• Remove and dispose of contaminated insulation within the affected attic work areas.

• HEPA vacuum roof decking, rafters or trusses, joists, blocking, top plates, and other attic surfaces within the affected work zone. Mechanically clean colonized retained wood using sanding, wire brushing, or another accepted method with concurrent HEPA collection.

• Apply an EPA-registered antimicrobial in accordance with its label. Encapsulant may be applied only where approved by the independent assessor after substrates are clean and dry; it shall not be used to conceal remaining growth.

• Roof-deck removal and replacement, roofing work, structural repair, and insulation replacement are excluded. Identify decking that remains visibly deteriorated or cannot be successfully remediated and notify the COR for separate action.

6.4 HVAC Remediation and Flex-Duct Removal

• Shut down, de-energize, and seal the HVAC system before disturbance. Coordinate lockout/tagout with the facility representative.

• Remove and dispose of the contaminated flex-duct branch serving the conference room. HEPA clean the accessible connection points and temporarily seal openings with durable polyethylene and tape pending separate duct replacement.

• Remove and clean affected registers, grilles, and boots by HEPA vacuuming and wet wiping in containment. Components that cannot be effectively cleaned shall be bagged, labeled, and turned over to the COR or disposed of as directed. Replacement is excluded.

• Professionally clean the air-handler interior, including coil surfaces, drain pan, blower wheel and housing, cabinet, and accessible interior surfaces. Remove the blower assembly as necessary for access.

• Remove contaminated or deteriorated air-handler interior insulation identified by the assessment report. Replacement lining, coatings, filters, equipment repairs, duct replacement, balancing, and system commissioning are excluded.

• Do not restart the HVAC system after remediation unless the Government confirms that removed components and insulation have been restored under separate work and provides written authorization.

6.5 Temporary Humidity Control and Drying

• Provide commercial dehumidification during remediation and drying to maintain interior relative humidity at or below 55 percent.

• Provide calibrated temperature/RH data loggers in the East Office, West Office, main/conference room, and a representative common area. Record at 15-minute intervals.

• Before clearance testing, demonstrate at least 72 continuous hours at or below 55 percent RH and acceptable substrate moisture levels. Wood moisture content shall be 16 percent or less unless the accepted Work Plan establishes a more appropriate material-specific criterion.

• Permanent dehumidification equipment, HVAC modifications, and correction of moisture sources are excluded. Submit documented observations and recommendations for separate Government action.

6.6 Cleaning and Antimicrobial Treatment

• Clean all affected work areas using the sequence: initial HEPA vacuum; mechanical cleaning as needed; antimicrobial damp wipe using label-required dwell time; and final HEPA vacuum.

• Remove porous materials with visible growth or direct water damage within the defined remediation limits unless the independent assessor approves retention in writing.

• Clean exposed structural surfaces and nonporous contents within containment. Do not rely on fogging, spraying, ozone, or encapsulation as a substitute for physical removal and cleaning.

• Complete final cleaning not more than 24 hours before the required settling period begins.

6.7 Mold-Remediation Turnover Condition

• After successful clearance, leave remediated wall cavities, attic areas, and HVAC openings clean, dry, and accessible for the Government's separate reconstruction contractor.

• Install temporary 6-mil polyethylene dust barriers over open wall cavities and duct openings after clearance. Clearly label temporary barriers and do not conceal remediated substrates with permanent materials.

• Remove remediation equipment and containment only after written clearance. HEPA clean the work areas, decontamination routes, and Government-designated staging areas.

• Reconstruction, permanent enclosure, insulation replacement, drywall, painting, trim, window and moisture-source repair, roof work, electrical work, plumbing work, and permanent HVAC restoration are expressly excluded.

7. POST-REMEDIATION VERIFICATION

7.1 Independent Assessor

USFWS will retain and pay an independent Florida-licensed mold assessor or qualified industrial hygiene professional to perform post-remediation verification (PRV), unless the solicitation states otherwise. The remediation Contractor and its affiliates shall have no prohibited financial or organizational relationship with the assessor. The Contractor shall provide access, maintain containment, and coordinate testing with at least 72 hours notice.

7.2 Pre-Clearance Conditions

• All demolition, remediation, detailed cleaning, and drying are complete.

• No visible mold, suspect growth, dust, debris, standing water, or wet material remains in the remediated zones.

• Containment remains intact. Negative-air machines, air scrubbers, fans, and dehumidifiers shall be turned off for the settling period established by the independent assessor, anticipated to be 12 to 24 hours unless the assessor directs otherwise.

• The Contractor shall not apply antimicrobial products, disturb materials, or perform cleaning during the settling period.

7.3 Clearance Criteria and Failure

The independent assessor shall establish the PRV sampling locations, methods, detection limits, and acceptance decision consistent with the assessment protocol and IICRC S520. Acceptance shall be based on satisfactory visual inspection, absence of unresolved moisture, and laboratory results demonstrating indoor fungal ecology consistent with a successfully remediated environment. No numerical criterion in this SOW shall be interpreted as a federal exposure limit.

If a zone fails because of incomplete removal, inadequate cleaning, containment failure, premature equipment operation, or another Contractor-controlled condition, the Contractor shall reclean or re-remediate the affected zone and pay the reasonable cost of repeat testing. Government-caused delays, new water intrusion outside Contractor control, or newly authorized scope shall be handled under the contract terms.

8. DELIVERABLES AND REPORTING

• Daily report for each on-site workday, submitted weekly unless the COR requests same-day submission. Include labor, activities, areas, equipment, photographs, RH/temperature logs, pressure logs, moisture readings, waste quantities, safety incidents, delays, and discovered conditions.

• Waste receipts or manifests within three business days after disposal.

• Written out-of-scope conditions report identifying active leaks, deteriorated framing or decking, unsafe building conditions, and materials that could not be successfully remediated.

• Final Contractor Remediation Report within five business days after successful clearance, including chronological photographs, product records, equipment logs, daily reports, disposal records, and identification of temporary barriers or closures left for reconstruction.

• Independent PRV report furnished by the Government assessor and incorporated into project closeout.

9. QUALITY CONTROL AND ACCEPTANCE

• The Contractor is responsible for quality control and shall inspect the remediation work before requesting Government or independent-assessor inspection.

• Acceptance requires successful PRV, completion of the defined remediation and cleaning, correction of remediation punch-list items, complete deliverables, proper temporary closures, removal of waste and equipment, and a clean site.

• The Contractor shall correct, at no additional cost, incomplete removal, inadequate cleaning, containment failure, or other deficiencies attributable to its mold-remediation work.

• Acceptance of this contract does not constitute acceptance of the building for occupancy following reconstruction. Reoccupancy will be determined by the Government after separate repair and reconstruction work is completed.

10. CONTRACTOR QUALIFICATIONS

• Provide a Florida-licensed mold remediator responsible for and routinely present during remediation.

Personnel performing regulated mold-remediation services shall meet applicable Florida requirements and work under proper supervision.

• Demonstrate at least five years of commercial or institutional mold-remediation experience, including projects involving wall cavities, HVAC components, and toxigenic or water-damage indicator fungi.

• Provide an on-site competent person with authority to enforce the HASP and stop work.

• Use properly licensed HVAC personnel for air-handler and duct-system remediation where required by Florida law.

• Insurance requirements shall be established by the Contracting Officer in the solicitation and award documents.
