About this file
This is a Statement of Work (SOW) for HVAC ductwork and component cleaning services at Joint Base Charleston, Air Base Building 503, located at 101 E. Hill Blvd., JB Charleston, SC 29404, with an effective date of 31 July 2026. The contractor must perform all work in accordance with National Air Duct Cleaners Association (NADCA) and Institute of Inspection Cleaning and Restoration Certification (IICRC) standards, as well as all applicable OSHA and local regulations. The objective is to remove accumulated contaminants from the HVAC system to improve indoor air quality and system efficiency.
The contractor must be a NADCA-certified member in good standing and must have at least one on-site technician with current Air Systems Cleaning Specialist (ASCS) certification from NADCA, with proof of both certifications required with the quote. The scope includes cleaning of 4 Variable Air Volume (VAV) Air Conditioner Units, 3 Exhaust Fans (EF-1, EF-2, EF-3) with associated ductwork, 24 Fan Powered Boxes (FPBs), 26 VAV Boxes, and all supply and return air diffusers, registers, and grilles. The contractor must identify and remove all visible contaminants including dust, debris, mold, and particulate matter, with suspected mold immediately reported to the Contracting Officer. The contractor is responsible for characterization, containment, labeling, and lawful off-site disposal of all waste in accordance with local, state, and federal regulations, including preparation of RCRA Hazardous Waste manifests (40 CFR 261) prior to disposal, with government signing as the official waste generator. Project-related waste cannot be disposed of in Government-owned dumpsters.
Cleaning methodology must include HEPA-filtered contact vacuuming, compressed air with appropriate nozzles, proper agitation using brushes and whips suitable for ductwork materials, and HEPA-filtered negative air machines maintaining continuous negative pressure exhausted to the building exterior where possible. The contractor shall utilize existing access doors and install service access panels/doors in accordance with Sheet Metal and Air Conditioning Contractors' National Association (SMACNA) and NADCA standards if no adjacent access door exists, with all newly installed access doors properly sealed and insulated upon completion. Cleaning requirements include all interior surfaces of exhaust fans (including heat exchange coils, drain pans, fans, and mixing boxes), all interior surfaces of FPBs and VAV boxes (including heat exchange coils, pitot tubes, dampers, and internal components), and removal, cleaning, and reinstallation of all air devices. Post-project documentation must include a comprehensive report with work description, before-and-after photographs, summary of issues encountered and corrective actions taken, a signed statement certifying compliance with NADCA standards, and confirmation of proper waste disposal including copies of manifests and receipts. Visual inspection of all cleaned ductwork and components must verify compliance with NADCA standards.

1.0 Scope of Work
This Scope of Work (SOW) outlines the requirements for the cleaning of HVAC ductwork and components. The work will be performed in accordance with the National Air Duct Cleaners Association (NADCA) and Institute of Inspection Cleaning and Restoration Certification (IICRC) standards and guidelines, as well as all applicable Occupational Safety and Health Administration (OSHA) and local regulations. The objective of this project is to remove accumulated contaminants from the HVAC system to improve indoor air quality and system efficiency.
2.0 Contractor Qualification
2.1 The contractor must be a certified member in good standing of the NADCA. Proof of current company certification must be provided with the quote.
2.2 The contractor is responsible for ensuring that there is at least one (1) on-site technician during performance that possesses a current Air Systems Cleaning Specialist (ASCS) certification from NADCA. Proof of certification for the designated on-site personnel must be provided with the quote.
3.0 HVAC System Components:
This project involves the cleaning of the following HVAC system components:
3.1 Variable Air Volume (VAV) Units: 4 VAV Air Conditioner Units.
3.2 Exhaust Fans (EFs): EF-1, EF-2, and EF-3, including associated ductwork and components.
3.3 Fan Powered Boxes (FPBs): 24 FPBs.
3.4 Variable Air Volume (VAV) Boxes: 26 VAV Boxes.
3.5 Air Devices: Supply and return air diffusers, registers, and grilles throughout the designated areas.
4.0 Contractor Tasks
4.1 Source Removal and Disposal of Contaminants
4.1.1 Identify and remove all visible contaminants from the specified ductwork and components, including but not limited to dust, debris, mold, and other particulate matter. Suspected mold growth shall be reported to the Contracting Officer immediately.
4.1.2 The contractor is responsible for the characterization, containment, labeling, and lawful off-site disposal of all waste generated in accordance with local, state, and federal regulations. Waste that meets the definition of a RCRA Hazardous Waste (40 CFR 261) shall have a manifest prepared by the contractor prior to disposal. The contractor shall arrange for and package the waste, but the government shall sign the manifest as the official waste generator. The contractor shall not dispose of any project-related waste in Government-owned refuse dumpsters.
4.1.3 The contractor shall provide the Government with copies of all waste manifests, transport records, and landfill/disposal receipts as part of the post-project documentation.
4.2 Mechanical Cleaning Methodology
Utilize a mechanical cleaning methodology that includes:
4.2.1 Contact Vacuuming: Employing HEPA-filtered vacuum equipment to remove loose debris and contaminants.
4.2.2 Compressed Air: Using compressed air with appropriate nozzles to dislodge embedded contaminants.
4.2.3 Proper Agitation: Employing brushes, whips, and other agitation devices suitable for the specific ductwork and component materials to loosen and dislodge contaminants.
4.2.4 Negative Air Machines: Maintaining continuous negative pressure within the ductwork during the cleaning process using HEPA-filtered negative air machines to prevent the spread of contaminants into occupied spaces.
Negative air machines will be exhausted to the exterior of the building where possible.
4.2.5 Ensure that all cleaning methods are appropriate for the materials and construction of the ductwork and components to prevent damage. The contractor shall utilize existing access doors to reach all internal ductwork components. If no access door exists adjacent to an internal component that requires cleaning, the contractor shall install a service access panel/door in the sheet metal ductwork in accordance with Sheet Metal and Air Conditioning Contractors' National Association (SMACNA) and NADCA standards to facilitate thorough cleaning. All newly installed access doors must be properly sealed and insulated upon completion to maintain duct integrity.
4.3 Cleaning of Specific Components
