UFS 3-401-01 5 June 2026 UNIFIED FACILITIES SUPPLEMENT (UFS) APPROVED FOR PUBLIC RELEASE; DISTRIBUTION UNLIMITED MECHANICAL ENGINEERING UFS 3-401-01 5 June 2026 FOREWORD Unified Facilities Supplements (UFS) provide non-mandatory, supplemental information in support of Unified Facilities Criteria (UFC). Only UFC establish enforceable criteria. UFS are For Information Only (FIO) and exist to help users understand and apply UFC requirements. The purpose of UFS is to offer procedural guidance, best practices, lessons learned, examples, and explanatory materials that clarify how to meet UFC criteria. They may include step-by-step procedures, checklists, illustrations, or decision aids, but they do not create new requirements or modify UFC content. UFS are developed by Discipline Working Groups

verly congested drawings. 2-2.6 Sections and Elevations. Provide sections and elevations as required to supplement plan views. UFS 3-401-01 5 June 2026 5 2-2.7 Access Space. Identify space necessary to access and replace items that require maintenance, such as filters, coils, heat exchangers, tube bundles, strainers, and chillers on the drawings in three-dimensions. 2-2.8 Special Detailing. Provide details on the drawings necessary to ensure drainage for “winterizing” equipment where appropriate. 2-2.9 Equipment Schedules. The equipment installed on a project may be different from that used as the basis of design. Therefore, mechanical equipment schedules must reflect actual required equipment capacities as calculated, rather than capacities provided by manufacturers' catalog data. This he

REQUIREMENTS. The design analysis and drawing requirements chapter provides documentation requirements necessary to demonstrate compliance with mechanical engineering UFC. UFS 3-401-01 5 June 2026 2 CHAPTER 2 DOCUMENTATION REQUIREMENTS 2-1 DESIGN ANALYSIS. Submit the Design Analysis at a preliminary design stage equivalent to 35% design for concurrence of the results. The Design Analysis must consist of a Basis of Design Narrative and Calculations. Update the analysis as necessary as the design progresses. The results of this analysis are used for decision-making in reducing total life cycle cost, while meeting mission objectives. 2-1.1 Basis of Design Narrative. Provide a Basis of Design narrative as part of all design analysis. 2-1.1.1 User Requirements. Provide a description of ventila

aircraft maintained. Aircraft inspection occurs within the maintenance hangar. Table 7.2.38. Building Utility System Requirements for Maintenance Support Facility. System Requirements Mechanical Proper ventilation system and energy efficient HVAC system are required. Repair and reclamation shop requires 150-psi shop air and corrosion resistant drains. Applicable criteria include UFC 3-401-01 for mechanical. Electrical Industrial equipment typically requires 240- and 480-volt, three-phase electrical current. Use commercial grade convenience receptacles and special power outlets. Applicable criteria include UFC 3-501-01 for general electrical requirements, UFC 3-520-01 for interior electrical systems requirements, UFC 3-530-01 for interior and exterior lighting and controls requirements, UF

categorical pretreatment standards as indirect discharges using effluent limitation guidelines established in the categorical pretreatment standards. Direct UFS 3-240-01 05 June 2026 23 discharge usually requires extensive wastewater treatment to reduce pollutants and achieve effluent requirements. Refer to EPA 833-K-10-001 for direct discharge guidance. 14-5 CONVENTIONAL POLLUTANTS (40 CFR 401.16). Five conventional pollutants are defined in 40 CFR 401.16. 14-6 INDUSTRIAL POLLUTANTS. Industrial wastewater may contain toxic or non-conventional pollutants in addition to conventional pollutants. When a POTW has the capability to remove toxic pollutants from industrial wastewater the pollutants can end up in the POTW’s sludge. 14-6.1 Toxic Pollutants (40 CFR 401.15). 40 CFR 401.15 currently c
