57 MXG Paint Booth Upgrade

SOO-1 STATEMENT OF OBJECTIVES FOR Building 252 Paint Booth #2 NELLIS AIR FORCE BASE, NEVADA 14 July 2026 OFFICE OF THE BASE CIVIL ENGINEER NELLIS AIR FORCE BASE, NEVADA -- 1 of 4 -- SOO-2 STATEMENT OF OBJECTS 1. OVERVIEW: The existing environmental controls and HVAC system at building 252 paint booth #2 is not sufficient for current OSHA requirements and is beyond its expected life span. The Existing Booth has an approximate 1200 square foot cross sectional area. The existing booth is uninsulated and has a 100% outside air (OA) design at approximately 75 Feet per Minute (FPM) if averaged over the 1200 sqft. To increase the airflow through the booth to an average of 100 FPM this will require 120,000 total Cubic Feet per Minute (CFM). The equipment that is located Behind the Paint Hangar Building is insufficient to locate a 100% (OA) design. The system should be converted to a paint booth with 80/20 recirculation design. This is a turnkey project. All supporting work such as demolition and removal of equipment, electrical, piping, ducting, concrete pads, etc., and the addition or modification of equipment, electrical, piping, ducting, concrete pads, etc. will be covered under the contractors work. Equipment Parameters: Equipment shall meet the following requirements 1) Equipment Design Parameters a. Ambient Outside Air Design Conditions: The design of the mechanical systems is based on local 0.4% Nellis AFB, NV 2017 ambient data. Summer Cooling: 109.2° FDB/ 67.3° FWB Summer Dehumidification: 66.1° FDP/ 80.1° FMCDB Winter Heating: 28.5° FDB (heating) Note: The site conditions outlined above are based on historical climate data listed as 99.6% coincidence and is based on averaged data with assumed standard deviations. Climatic extremes will occur that fall outside of the conditions listed above. The extreme conditions are rare but may exceed the design capacities of the system. 2) Equipment Sizing: a. “Maintain Conditions Within the Window: The equipment will be sized to fluctuate within the tolerance window for temperature and humidity. Below are the operating windows of the Paint Booth. Spray/Brush-Roll (Summer) 65-70° F at 40% - 60% rH Spray/Brush-Roll (Winter) 65-70° F at 40% - 60% rH Ambient Cure 65-70° F, no humidity control 3) Coating Data (Type C Form 1 RAM) provided by Nellis AFB a. Spray application window on aircraft in the environmental range of 65-75° F at 40- 60% rH Paint Mode: The total airflow during paint mode is designed to be 120,000 CFM. Paint mode provides full air velocity in the booth to remove overspray. The airflow during paint mode recirculates 80% of the air and replaces 20% with fresh air. The temperature during paint mode is held in the range 65-70° F and humidity is held at 40%-60%. rH. -- 2 of 4 -- SOO-3 Ambient Cure Mode: The total airflow during cure mode is 120000 CFM. Cure mode is used to force-dry coatings after painting by providing an ambient temperature of 65-70° F for a set period of time. Humidity control is not provided during cure mode. Purge Sequence: The total airflow during purge mode is 120000 CFM. If there is an upset or alarm condition, such as a high LEL alarm, the air solenoid valves close to stop compressed air going to the spray operation and the fans continue to run to reduce VOC levels. The system will remain in purge mode until an operator checks the conditions and allows a reset. SCOPE: Provide the following replacement equipment for 252-2 Paint Booth to include removing all old equipment. 1) Replace Air handlers 2) Replace Chiller 3) Replace exhaust system 4) Replace all other sub components required to meet equipment design parameters 5) Upgrade electrical as required. 6) Equipment Installation, Commissioning & Training 7) Demolition and proper disposal of existing equipment will be required. 8) Prior to start of work, provide temporary construction fencing with privacy fabric at all openings to the airfield and secure to block wall. 9) At the end of each day and at the completion of the project, the contractor will clean all job- related debris from area. A post construction inspection will be conducted with contractor, CE and the customer. 10) Provide As-built drawings, owner manuals, and warranty information prior to close out of contract. 1. LOCATION: The project site is located at Nellis Air Force Base, Nevada. The Main Base is located approximately 9 miles north of downtown Las Vegas on Highway US 93 (Las Vegas Blvd.). NAFB consists of three main areas: the Main Base, Area II, and Area III. The specific project location is on the Main Base in Building 252, the Corrosion Control Facility, located at the intersection of Tyndal and Griffiss, NAFB, NV, 89084. 2. ENVIRONMENTAL PROTECTION: All work and the contractor’s operations shall comply with the requirements imposed by all applicable federal, state, local, and NAFB laws, regulations, codes, and permits (including NAFB Management Plan 12) concerning environmental protection. If required per the task in the area where work is to be performed, an asbestos- containing material and a lead-based paint test will be done by the 99 CES. -- 3 of 4 -- SOO-4 3. CONTRACTOR PERSONNEL: The contractor’s personnel shall conduct themselves in a professional manner. 4. QUALITY ASSURANCE: The government, through the 99 CES Representative, will periodically evaluate the contractor’s performance in accordance with the specific contract performance requirements. 5. WORKING HOURS: Standard working hours are from 7:00 a.m. to 4:00 p.m. Monday through Friday excluding Federal Holidays and the day after Thanksgiving. 6. GENERAL CONDITIONS: All work must be in compliance with and conform to industry standards and applicable manufacturer’s recommendations. Any electrical wiring, connections, and structural designs shall be installed IAW latest version of the NFPA 70 National Electric Code (NEC), Uniform Mechanical Code, and NFPA 54, ASME CSD-1 (Controls & Safety Devices).
