B301 20th IS Controls Upgrade and Duct Cleaning PWS.docx

Performance Work Statement Project Title: Replace degraded Excel 5000 series controllers at B301 20th IS NextGen Work Task #: 15320719 & 15759486

1. Objectives:

This scope of work is to provide replacement of degraded and obsolete Excel 5000 series controllers at the B301 20th IS space, which are at their end of service life, and full programming of those replacements, including graphics. This project shall also replace several associated control & operation components. The controller series is obsolete and replacement parts are no longer being manufactured, which causes extreme delay times and often emergent upgrades for repairs. These controllers serve top priority mission critical functions housed within this area.

The existing controls that need to be replaced consist of the following:

· Controls for AHU-1 & AHU-3 located in the 20th IS East Mech Rm area that need to be replaced

· 4 EA Honeywell pneumatic zone damper actuators model

· 2 EA HW actuators & valves - Honeywell model

· AHU supply & return air temperature sensors

· 2 EA XL 500 controllers

· 4 EA pneumatic damper actuators (Supply, Return, Fresh Air (Mixed), Relief), each currently supplied for 30 psi pneumatic air

· Controls for AHU-2, 4, & 5 located in the 20th IS West Mech Rm area that need to be replaced

· 2 EA XL 500 Controllers

· 2 EA HW actuators & valves - Honeywell

· AHU supply & return air temperature sensors

· 7 EA pneumatic damper actuators (Supply, Return, Fresh Air (Mixed), Relief), each currently supplied for 30 psi pneumatic air

· 2 EA Honeywell pneumatic zone damper actuators

· 5 EA Honeywell electronic zone damper actuators

· Additionally, scope shall include removal of humidifiers at AHU-4

· Additionally, scope shall include replacement of CW & HW coils at AHU-4 The identified controller replacements shall be of like capacity in the Honeywell Tridium N4 product line. Replacement components such as valves, actuators, and sensors shall be compatible with the new controllers and of like capacity & function to the existing components, but do not need to be a particular brand. All pneumatic damper controls and missing damper controls must be converted to new electric actuator control. Database and programming information shall be migrated from the old controller units to the new units as part of this project. The BMS (Honeywell EBI) graphics shall be updated to match all changes done.

Additionally; this scope of work shall provide cleaning of the interior surface of the entire supply and return ductwork system serving the west secure area of the 20th IS offices in B301, as well as the break room and 820th office area. Total estimated area is ~30,000 sq ft. Additionally, this project shall clean the surface of the air supply and return and exhaust grills/vents and the interior of the Air Handling Units serving those sections (AHU-2, 4, & 5). The intent of this project is to remove dust, debris, loose particulates, and adhered grime that have accumulated over the years and continue to provide a negative impact to building personnel. The supply and return and exhaust ductwork being in safe and healthy condition is critical for the health and safety of the Airmen working in the building.

The existing supply, return, and exhaust ductwork consist of several sizes and types of ductwork running throughout the 20th IS. In general there are several main branches of supply and return lines from three air handlers. Ductwork is located both above false ceiling and throughout open areas. Access to the AHUs are through the mechanical room outside the office areas, access through a different portion of the facility. Ductwork sizes range from ~72”x24” near the Air Handlers to 6”-12” in diameter/square on the distribution lines. Distribution lines consist of both rigid metal and flex-duct. Access points exist at the AHUs and at each supply and return vent. Any service openings needing to be created for performance of the work shall comply with ACR 2021 Section 4.2.

The identified requested service is to provide cleaning of the interior of the identified ductwork. Cleaning of the entire ductwork system to remove dust and loose particulates must be performed. Cleaning and sanitizing of the supply and return vent/grills surfaces must also be performed. The work as performed must comply with ACR 2021 standards and NADCA recommendations. Throughout the cleaning process the HVAC system and associated air duct shall be kept at an appropriate negative differential pressure relative to the indoor non-work area. When utilizing vacuum collection equipment exhausting indoors it shall be HEPA-filtered and be capable of retaining dislodged debris. All equipment used to create negative duct pressurization that does not have HEPA filtration shall be exhausted outdoors. Cleaning methods for the interior of the ducts, vents and grills, and Air Handlers shall be performed per ACR 2021 Section 4. This work shall include cleaning of any in-line blowers or coils. The work shall include preparation of the work area to protect furnishings from dirt or damage, and cleanup of the work area after duct cleaning to remove any mess created.
