Statement of Work Building 316 Duct Cleaning Mold Remediation

C.1 SCOPE OF WORK

The work includes the provision of all labor, materials, equipment, and incidental related work to perform duct cleaning and mold remediation services in the Advanced Automation Building 316 at the Federal Aviation Administration (FAA) William J. Hughes Technical Center (WJHTC).

The duct cleaning and mold remediation services will consist of a portion of the HVAC systems serving the Advanced Automation Building (B316). The Contractor will be responsible for cleaning the entire HVAC systems from all points of entry, including return ductwork, supply ductwork, outdoor air intakes, air handling units, and all rigid ductwork and components up to and after the Variable Air Volume (VAV) boxes at the low pressure end of supply. The Contractor must then apply an anti-microbial coating to the interior-insulated ductwork to prevent future mold/bacterial growth. Additionally, the contractor must replace all flexible supply ductwork present between the low- pressure supply plenums/VAV boxes and the supply diffusers, as well as the cleaning of all supply diffusers.

This project will be broken down as a Base Bid with three (3) options, all of which encompass the same work as defined above and in accordance with the additional requirements set forth hereafter.

The bid breakdown depicted below indicate the location and details of the portion of the systems to be serviced in relation to the bid breakdown.

Base Bid

The base bid will consist of (5) systems: AH-1 & AH-1A, AH-2 & AH-2A, AH-3 & AH-3A, AH- 4 & AH-4A, and AH-5. All of the auxiliary (“A”) systems are tied to their respective main systems and function in parallel. The auxiliary air handlers are located immediately adjacent to the main units and have a short run of ductwork connecting them in parallel to the main systems they supplement.

1. AH-1 (87T Cooling and 47T Heating) & AH-1A Serve the 3rd floor office spaces. These office areas contain both cubicle farms and individual offices.

2. AH-2 (87T Cooling and 47T Heating) & AH-2A Serve the 2nd floor office spaces east side.

These office areas contain both cubicle farms and individual offices.

3. AH-3 (120T Cooling and 64T Heating) & AH-3A Serve the 4th floor office spaces. These office areas contain both cubicle farms and individual offices.

4. AH-4 (87T Cooling and 47T Heating) & AH-4A Serve the 2nd floor office spaces west side.

These office areas contain both cubicle farms and individual offices.

5. AH-5 (77T Cooling and 70T Heating) Serves the 3rd floor lab spaces. The laboratory areas consist of large open rooms with computer server farms spread throughout. Only the ductwork associated with AH-5 is to be cleaned in the lab spaces, Computer Room Air Conditioner (CRAC) units and the underfloor system are not included in this scope.

Once the FAA Safety Team reviews the safety plan and training records, the applicable confined space permits will be issued.

5. Specialization

The contractor must have an Air Systems Cleaning Specialist (ASCA) on site each workday to ensure all cleaning is performed in accordance with NADCA Standards and Guidelines as per NADCA Certification.

C.1.2 HVAC System Cleaning Specifications and Requirements

This section defines the minimum requirements necessary to render HVAC components clean, and to verify the cleanliness through inspection and/or testing in accordance with items specified herein and applicable NADCA standards. The Contractor will be responsible for the removal of visible surface contaminants and deposits from within the HVAC system in strict accordance with these specifications.

The HVAC system includes any interior surface of the facility’s air distribution system for conditioned spaces and/or occupied zones. This includes the entire heating, air-conditioning and ventilation system from the points where the air enters the system (return, outdoor air intake, etc.) to the points where the air is discharged from the system.

The return air grilles, return air ducts (except ceiling plenums and mechanical room) to the air handling unit (AHU), the interior surfaces of the AHU, mixing box, coil compartment, condensate drain pans, humidifiers and dehumidifiers, supply air ducts, fans, fan housing, fan blades, air wash systems, spray eliminators, turning vanes, filters, filter housings, reheat coils, and supply diffusers are all considered part of the HVAC system. The HVAC system may also include other components such as dedicated exhaust and ventilation components and/or make-up air systems.

C.1.3 HVAC System Inspections and Site Preparations

1. System Damage / Mold Growth Damaged system components found during performance must be documented with photographs and brought to the attention of the COR immediately (including after hours).

Excessive Mold or suspected causes of mold growth (leaks, clogged drains, etc) on HVAC systems must be brought to the attention of the COR. Any damage discovered during the execution of this project will be quoted separately and handled as a change order to the base bid.

2. Site Preparation Desks, shelves, and any other furniture or equipment in the vicinity of cleaning activities must be covered with plastic sheeting or tarps prior to starting work and covering must be removed at the end of each workday. Any remaining dust, dirt, or debris must be vacuumed and/or wiped with a clean rag. Heat-generating equipment must not be covered unless approved by the Government.

C.1.4 General HVAC System Cleaning Requirements

1. Particulate Collection Mechanical cleaning operations must be undertaken only with Particulate Collection Equipment in place, including adequate filtration to contain debris removed from the HVAC system. Where the Particulate Collection Equipment is exhausting inside the building, HEPA filtration with 99.97% collection efficiency for 0.3-micron size particles must be used. When the Particulate Collection Equipment is exhausting outside the building, precautions must be taken to locate the equipment down wind and away from all air intakes and other points of entry into the building.

2. Component Cleaning Cleaning methods must be employed such that all HVAC system components must be visibly clean as defined in applicable standards (see NADCA standards). Upon completion, all components must be returned to those settings recorded just prior to cleaning operations.

3. Air-Volume Control Devices Dampers and any air-directional mechanical devices inside the HVAC system must have their position marked prior to cleaning and, upon completion, must be restored to their marked position.

4. Service Openings The contractor must utilize service openings, as required for proper cleaning, at various points of the HVAC system for physical and mechanical entry, and inspection. Work inside ducting is considered permit required confined space.

4.1 Considerations

a. Contractor must utilize the existing service openings already installed in the HVAC system where possible.

b. Other openings must be created where needed and they must be created so they can be sealed in accordance with industry codes and standards.

c. Closures must not significantly hinder, restrict, or alter the airflow within the system.

d. Closures must be properly insulated to prevent heat loss/gain or condensation on surfaces within the system.

e. Openings must not compromise the structural integrity of the system.

f. All service openings must be of the “twin cam” type, size 12”x12” minimum, unless not physically possible due to size or clearance concerns, so as they can be re-opened for future inspection or remediation. If 12”x12” twin cam type door is unable to be used, a smaller size twin cam type door is permitted. Sheet metal patches must be avoided unless no other twin cam type door is possible in that location. All service openings must be clearly marked and must have their location reported to the government in project report documents. These locations should also be noted on system drawings for reference in the future.

g. Any insulation that is removed or disturbed during the course of the job must be repaired or replaced with new in-kind insulation and sealed properly to prevent heat loss/gain or condensation on surfaces within the system.

5. Air handling units, terminal units (VAV, Dual duct boxes, etc.) and blowers and exhaust fans

The contractor must ensure that supply, return, and exhaust fans and blowers are thoroughly cleaned. Areas to be cleaned include blowers, fan housings, plenums (except ceiling supply and return plenums), scrolls, blades, or vanes, shafts, baffles, dampers and drive assemblies. All visible surface contamination deposits must be removed in accordance with NADCA standards. All controls, air-measuring devices, and any other components located within ductwork or VAV boxes must be removed and/or properly protected to avoid damage during the cleaning process.

Exceptions: Any exhaust system NOT directly tied to an air handler must NOT be cleaned.

Example: Bathroom exhaust fans and ductwork that function independently of the air handling system must not be cleaned.

Any components damaged through lack of removal or protection, use of cleaning products, or negligence will be contractor’s responsibility to replace with new and restore to normal operating conditions.

In the event that any ceiling tiles are damaged during the cleaning process, the government has a stock of replacement tiles available for use. It is the expectation of the government that the contractor will do everything within its power to minimize any damage caused to the ceiling tiles during the performance of work.

6. Contractor must:

a. Clean all air handling unit (AHU) internal surfaces, components and condensate collectors and drains.

b. Assure that a suitable operative drainage system is in place prior to beginning wash down procedures.

c. Clean all coils and related components, including evaporator fins. Corrosive cleaning agents are prohibited.

d. Replace all filters (pre, bag, box, or other) with the appropriate size and existing MERV rating immediately following the cleaning of the air handling unit(s).

o Roll filters are not to be replaced, they are to be cycled.

o AHU-1: (15) 24x24x2 Pleated Filters o AHU-1A: (4) 12x48 Panel Filters w/ Metal Frames for Support o AHU-2: (15) 24x24x2 Pleated Filters o AHU-2A: (4) 12x48 Panel Filters w/ Metal Frames for Support o AHU-3: (20) 24x24x2 Pleated Filters, (4) 12x24x2 Pleated Filters o AHU-3A: (4) 16x60 Panel Filters w/ Metal Frames for Support o AHU-4: (15) 24x24x2 Pleated Filters o AHU-4A: (4) 12x48 Panel Filters w/ Metal Frames for Support o AHU-5: (6) 24x24x2 Pleated Filters, (2) 12x24x2 Pleated Filters o RTU-1: (2) 20x25x4 Pleated Filters o RTU-2: (2) 20x25x4 Pleated Filters

e. Replace all biocide packs/tablets currently installed in condensate pans or within air handling units with new, similar sized/performing biocide.

f. Clean all HVAC systems in the direction of airflow:

o Return ductwork, chutes, risers o Outdoor air intake ductwork o Air handling unit and all components o Supply ductwork, risers, chutes, and components up to distribution devices

(diffusers, air curtains, etc.)

g. Linear diffusers must be cleaned, and if the diffusers are internally lined with insulation, they are to be removed, disassembled, cleaned, encapsulated, reassembled, and reinstalled.

i. Replace all flexible ductwork connecting diffusers to VAVs or low pressure ductwork. R value of replacement flexible ductwork must be R4.2 or better.

7. Mechanical Cleaning Methodology

7.1 Biocidal Agents and Coatings

a. Cleaning non-porous materials – Clean any non-porous materials using HEPA vacuums and a detergent-and-water based solution. Allow materials to dry thoroughly.

b. Removal of affected porous materials – Remove intact material to minimize mold spore aerosols. Place effected materials into disposal containers immediately after removal.

Removal of insulation or other materials must be approved after notification of discovery.

c. Only biocidal agents registered by the U.S. Environmental Protection Agency (EPA) specifically for use within HVAC system must be used.

d. Biocidal coating products for both porous and non-porous surfaces must be EPA registered water-soluble solutions with supporting efficacy data and Safety Data Sheets (SDS) records.

e. Biocidal coatings must be applied in strict accordance with manufacturer’s instructions.

Coatings must be sprayed directly onto interior ductwork surfaces, rather than “fogged” downstream onto surfaces. A continuous film must be achieved on the surface to be treated by the coating application. Application of any biocidal coatings must be in strict accordance with manufacturer’s minimum millage surface application rate standards for effectiveness.

f. Mold and fungal growth must be cleaned and removed from all ductwork interior, including insulation surfaces throughout the system.

g. HVAC system must be put under negative pressure during mold remediation work.

h. Any part of the system that is internally lined with insulation, be it supply ductwork, return ductwork, or exhaust ductwork, the air handlers themselves, must be encapsulated.

System components that are NOT internally lined and are just sheet metal only need to be cleaned, not encapsulated.

i. Any desired encapsulant substitute must meet performance specifications as set forth in the SOW and pre-approved by the FAA prior to application.

7.2 Anti-Microbial Coatings

Anti-microbial coatings should not be used for biocide purposes, but rather as a preventative measure on porous materials not removed due to project limitations. Apply the anti-microbial coatings after a thorough cleaning of material’s surfaces. The FAA Safety Office must approve any anti-microbial coating other than White Fosters 40-30.

8. Cleanliness Verification

8.1 General

Verification of HVAC System cleanliness will be determined after mechanical cleaning and before the application of any treatment or introduction of any treatment-related substance to the HVAC system, including biocidal agents and coatings. An FAA representative must be present for cleanliness verification.

8.2 Visual Inspection

The HVAC system must be inspected visually to ensure that no visible contaminants are present.

An FAA representative must be present during visual inspections for cleanliness.

a. If no contaminants are evident through visual inspection, the HVAC system must be considered clean; however, the Government, at the Government’s expense, reserves the right to further verify system cleanliness through gravimetric analysis testing as specified in SOW paragraph C.1.10.1.

b. If Cleanliness verification of any portion of the system or visible contaminants are evident through visual inspection, those portions of the system where contaminants are found/visible must be re-cleaned at no additional cost to the Government and subjected to re-inspection for cleanliness.

9. Photo documentation

Photo Documentation will be provided by the Contractor from before and after all cleaning is completed.

a. Photo documentation will serve as validation of the success of the HVAC system cleaning, in addition to the visual inspections and optional gravimetric analysis.

b. Photo documentation must be included in each day’s daily report, depicting before and after of areas cleaned, including a caption notating the location.

10. Post-Cleaning Verification Testing

Wipe or swab samples will be collected and analyzed by the Government at their discretion for direct microscopic assessment for microbials upon completion of cleaning. Duct will be considered to be successfully remediated when determined visually cleaned and when post-cleaning samples reveal mold levels lower than pre-cleaning.

10.1 Gravimetric Analysis (NADCA Vacuum Test)

a. NADCA Vacuum Testing (Gravimetric Analysis) at various points of the HVAC system may be performed to determine system cleanliness.

b. A cleanliness level of <0.75mg/100cm2must be achieved for the system to be considered “clean” as per NADCA guidelines.

c. Results will be a partial validation to the success of the cleaning, in addition to the visual inspection and photo documentation.

d. If gravimetric analysis determines that levels of debris are equal to or lower than those levels specified in applicable NADCA standards, the system must be considered clean and must have passed cleanliness verification.

e. If gravimetric analysis determines that levels of debris exceed those specified in applicable NADCA standards, the system must not be considered clean and those sections of the system, which failed cleanliness verification, must be re-cleaned at the expense of the HVAC system cleaning contractor.

11. Damage

Any damage incurred by the contractor during completion of the contract must be the responsibility of the contractor to repair or replace. This includes damage to the HVAC system, any changes to the HVAC system that reduces the integrity or efficiency of the system, and any damage to personnel or property in the area of work.

C.2 Site Conditions
