APPLICABLE CRITERIA AND COORDINATION WITH LOCAL AUTHORITIES

2.1 APPLICABLE CRITERIA. Applicable design and construction criteria references are listed in this Statement of Work and in the Specifications of this RFP.

Criteria shall be taken from the most current references as of the date of issue of the RFP, unless otherwise noted. However, following contract award, Contractor shall bring any criteria updates to the attention of the Contracting Officer. Referenced codes and standards are minimum acceptable criteria. Administrative, contractual, and procedural features of the contract shall be as described in other sections of the RFP. Sources for criteria documents are listed below.

2.1.1 In order for a facility to be occupied by Department of Defense personnel, the design and construction must meet specific requirements. The Government’s primary guidance on fire protection is UFC 3-600-01, Design – Fire Protection Engineering for Facilities. Design and construction of Army Reserve real property improvements shall comply with UFC 3-600-01, and shall comply with the specific applicable requirements of IBC, NFPA 101, and other commercial codes and standards that are referenced in UFC 3-600-01. The Contractor shall complete a Fire Protection/Life Safety Code Submittal form, for the project to demonstrate compliance. The form is available on the Corps of Engineers, Louisville District, Army Reserve Customer Website.

2.1.2 Design and construction of Army Reserve real property improvements shall also comply with the requirements of this document and with the current edition of the industry and Federal Government standards listed in this RFP. Where UFC 3-600-01 or any other Federal Government standard refers to other Federal Government standards not listed in this RFP, the standards not listed in this RFP do not apply

2.1.3 Some State and local code and regulatory agencies may not have jurisdiction over Federal Government construction on Federal property. However, the Army Reserve wishes to comply with State and local codes and regulations, and the Contractor remains responsible for such compliance. Therefore, design and construction of Army Reserve real property improvements shall also comply with all current and applicable State and local codes, and with all other applicable laws and regulations governing development, design and construction at the site. If certain of such requirements appear particularly onerous, or hamper required functionality of the project, the Contractor may recommend the Government waive the requirement or implement a lesser requirement. The Government’s acceptance of such recommendations is not assured.

2.1.4 Where any of the applicable requirements conflict, the most stringent shall govern. In no case shall building code, fire protection and life safety requirements be reduced below those required in UFC 3-600-01 and this RFP.

2.1.5 The requirements of the International Mechanical Code (IMC) and International Plumbing Code (IPC) shall apply except as follows. Where conflicts exist between the IMC and IPC, and the requirements of this document, this document shall govern. Where the IMC or IPC references the ICC Electrical Code, the NEC National

Corrected Final Submittal-July 2019 01 02 00.00 48 Part 2 - 2 of 10

Electrical Code shall be the applicable code. Where the IMC references the International Fuel Gas Code, the NFPA 54 National Fuel Gas Code shall be the applicable code. Where the IMC or IPC references the International Fire Code, the National Fire Codes published by the National Fire Protection Association (NFPA) shall be the applicable code. Where the IMC or IPC references the International Energy Conservation Code, the ASHRAE Standard 90.1 Energy Standard for Buildings – Except Low Rise Residential Buildings shall be the applicable reference. The requirements of ASHRAE Standard 62.1 Ventilation for Acceptable Indoor Air Quality shall be used in lieu of the ventilation requirement contained in the IMC.

2.1.6 The primary criteria and guidance for detailed design of Army Reserve Training Centers is UFC 4-171-05, Army Reserve Facilities (Design Guide or DG). The Contractor shall follow the guidance of the DG in developing the project design, unless this RFP directs otherwise. For the purposes of this RFP, when the word “should” is used in the DG, it indicates a mandatory requirement for this project. When the DG references Government criteria documents not referenced in this RFP, those criteria do not apply to this project.

2.1.6.1 The DG is considered the primary criteria, if conflicting with the UFC's and other criteria, and shall be followed as first precedence.

2.1.6.2 The requirements of the Army Reserve Design Process and Submittal Requirements (DPSR), shall take precedence over any conflicting UFC requirements regarding Predesign, Design, Post Design Services, and Submission Requirements.

2.1.7 Best Practices (Chapters or Appendices) listed in any UFCs shall be considered recommendations and are not contract requirements, unless otherwise noted in this RFP.

2.1.8 Accessibility – Design and construction must comply with ADA-ABA Accessibility Standard for Department of Defense Facilities and UFAS, whichever is most stringent. Buildings shall be considered to be “commercial facilities” under ADA-

ABA.

2.1.9 Design and construction shall comply with applicable Federal laws and regulations, such as EPA Clean Water and Clean Air Act and OSHA requirements.
