Anderson AFB 36 FSS CDC DUCT CLEANING

This technical drawing and engineering schematic details the HVAC, piping, and electrical wiring system modifications for the "Add to and Alter Child Care Center" project at Andersen Air Force Base in Guam. Created by the Strategic Air Command Civil Engineering division under project number AND 80-0042, the document provides detailed mechanical layouts, control wiring, and refrigeration schematics. Key components of the document include: - A detailed "Sequence of Operation" outlining the automated logic for two Air Handling Units (AHUs), condensing units, damper motors, liquid line solenoid valves, smoke alarms, and a heat reclaim water pump. - Air duct and ventilation details, including a typical air supply outlet diagram, turning vane schedule, and an outside air intake detail specifying a 16"x12" louvered intake designed for a 600 CFM air flow capacity. - A schematic refrigeration piping diagram showing connections between existing and new equipment, including a new heat reclaim device, existing 40-gallon hot water heaters, and a new condensing unit package. - 110 VAC A/C control wiring and heat reclaim wiring diagrams detailing the electrical connections between thermostats, humidistats, valves, and the AHUs. This drawing serves as a critical technical reference for contractors bidding on or executing HVAC system upgrades, ensuring proper integration of new climate control and energy recovery systems with existing base infrastructure.

This government engineering drawing and technical specification sheet outlines the air conditioning system layout, equipment schedule, and installation details for modifications to the Child Care Center at Andersen Air Force Base in Guam. Prepared by the Strategic Air Command Civil Engineering division, the project involves adding to and altering the facility's existing HVAC infrastructure. The document specifies the procurement and installation of key mechanical components, including a 34.4-ton air-cooled condensing unit, upgrades to an existing Trane Climate Changer air handling unit (increasing airflow to 7,271 CFM and cooling capacity to 26.0 tons), and a new 7.5-ton draw-through air handling unit. Additional equipment requirements include a heat reclaim device for hot water generation, multiple wall exhauster fans ranging from 200 to 1,500 CFM, and a new kitchen range hood with an integrated fire protection system. Construction notes mandate compliance with AMCA and UL safety standards, proper insulation of supply and return ducts in unconditioned spaces, and the use of specific copper tubing (Type-K and Type-L) for refrigeration piping. The layout plan integrates new improvements with the existing system to ensure comprehensive air distribution, moisture control, and heating/cooling zoning throughout the facility.

This technical document is an engineering design and equipment schedule for upgrading the air conditioning system at the Child Care Center on Andersen Air Force Base in Guam, managed by the Strategic Air Command Civil Engineering. The project involves modifying the existing HVAC infrastructure to improve environmental controls. Key components of the scope of work include: - **Condensing Unit:** Installation of a new 34.4-ton, air-cooled, self-contained condensing unit with dual semi-hermetic compressors. - **Air Handling Units:** Upgrading an existing Trane Climate Changer (Model 12) to increase airflow from 4,900 CFM to 7,271 CFM, including a new 7.5 HP fan motor drive and a 300,000 Btu/Hr reclaim reheat coil. Additionally, a new 7.5-ton modular draw-through air handling unit will be installed. - **Heat Reclaim and Exhaust:** Installation of a 120,000 Btu/Hr hot water heat reclaim device and three new wall exhauster fans ranging from 200 to 1,500 CFM. - **Construction Requirements:** Ductwork in non-conditioned spaces must be insulated, and refrigeration lines must use Type-K (high side) and Type-L (low side) copper tubing with silver-soldered joints. All air distribution inlets and outlets must maintain a noise coefficient (NC) level of 40 or less. The document includes detailed section layouts, schematic symbols, and coordination approvals from base civil engineering, ground safety, and bioenvironmental engineering.

This Performance Work Statement (PWS) details the requirements for a one-time inspection and cleaning of the HVAC ductwork and associated system components at the Child Development Center (Facility 1625) on Andersen Air Force Base (AAFB) in Guam. The primary objective is to ensure the systems operate safely, with all services completed no later than March 31, 2027. The contractor must provide all necessary personnel, equipment, tools, materials, supervision, and quality control. All work must align with the National Air Duct Cleaning Association (NADCA) ACR standards, manufacturer instructions, and applicable federal, local, and territorial environmental and safety regulations. Due to the facility's nature, the contractor must adhere to strict precautionary protocols regarding potential mold and asbestos. Localized mold encountered during inspection must be remediated immediately under ANSI/IICRC S520 and EPA guidelines, while suspected asbestos requires immediate work stoppage, notification within two hours, and certified abatement. Administrative and operational requirements include submitting a Quality Control Plan (QCP) within 10 days of contract award, coordinating utility outages 30 days in advance, and performing work outside normal operating hours to prevent disrupting government operations. Additionally, the contractor is responsible for securing base access credentials, ensuring personnel possess required licenses, and conducting minor repairs under $2,500. A final completion report must be submitted to the Contracting Officer's Representative (COR) within five business days of completing the on-site services.

This federal Request for Quote (RFQ), solicitation number FA524026Q0043, is issued by the 36th Contracting Squadron (36 CONS) of the Department of the Air Force. The solicitation seeks a contractor to perform a one-time inspection and cleaning of the air ducts at the Child Development Center located on Andersen Air Force Base (AAFB) in Guam. Classified under NAICS code 561790 (Other Services to Buildings and Dwellings) with a size standard of $9 million, this acquisition is set aside 100% for small businesses. The contract will be awarded as a Firm-Fixed-Price contract based on a "best value" evaluation of two primary factors: Price and Technical Approach. Offerors are required to submit separate volumes for price and their detailed technical approach rather than simply restating the Performance Work Statement (PWS) requirements. Offers are due by September 14, 2026, at 12:00 PM local time, and must remain valid for 60 calendar days. The anticipated period of performance runs from September 30, 2026, through December 31, 2026. The solicitation incorporates standard federal provisions, including WAWF electronic invoicing instructions, strict base access requirements, and a zero-tolerance policy prohibiting marijuana use or possession on federal property.
