7.2 EXTERIOR ELECTRICAL DISTRIBUTION

7.2.1 Primary Service

All medium voltage primary work will be performed in accordance with Tinker Electrical Standards by the local electric utility, Oklahoma Gas & Electric (OG&E). Voltage, capacity of service, type of service, transformer size, etc.

are all determined by the utility, based on load information provided by Tinker.

Primary service is 12,470V, 3-phase, 4-wire, wye, multi-point grounded.

Primary service to the site will be underground.

7.2.2 Primary Source and Point of Connection

The primary system serving the facility is owned by OG&E. Preliminary coordination has determined the BACH construction contractor is responsible for the following:

• Provision of underground ducts and service lateral conductors from the utility transformer to the connection at the service entrance equipment.

• Furnishing service lateral compression lugs to OG&E.

• Coordinating with OG&E for all work related to the electric utility system during construction.

OG&E is responsible for the following:

• Primary service to the facility pad-mount transformer(s).

• Pad-mounted transformer(s) and pads.

• Termination of service lateral conductors (compression lugs furnished by the building contract) at the utility transformer and connection at the transformer secondary connection service points.

Analysis of the building electrical load sets aside the option to provide a single service for the building and warrants (2) electrical services to serve the hangar building. This configuration agrees with the guidance of UFC 3-520-01 and naturally coordinates with the building plan, north shops and south admin area separated by a large hangar bay. This configuration also supports design criteria for future electrification of the Hangar.

Hangar electrical service sizing calculations are provided in Appendix 7.2. As indicated in the calculations, the Hangar North service should be served from a 1,000 kVA transformer and the south service should be served from a 1,500 kVA transformer. Appendix 7.3 provides calculations for the proposed service

Tinker Air Force Base, Oklahoma 65% Design Submittal

Design Analysis - 94 lateral conductors. These conductors remain sized to accommodate future electrification as agreed in the building de-electrification discussions.

Final transformer loading calculation will follow coordination with OG&E to determine the service source for all loads originating from the BACH project;

the Hangar (North and South), Lift Station, Hangar Doors, and Site Lighting.

One-line diagrams and panelboard schedules are provided in Appendix 7.4.

Additional calculations and any required revisions will be provided at the prefinal submittal.

The administrative support office areas are classified as Business (Group B) use occupancies by IBC.

The shop and maintenance areas are classified as Moderate-Hazard Factory Industrial (Group F-1) use occupancies by IBC.

There are accessory Assembly (Groups A-2 and A-3) use areas for meeting and dining (break) / tornado shelter spaces.

9.4.2 Mixed Use and Occupancy Separations

The BACH is a nonseparated, mixed-use building of Groups B, F-1, and S-1 use areas with accessory Group A-2 and A-3 areas.

9.4.3 Incidental Uses

There are no rooms or areas within the BACH that fit the IBC Table 509.1 definitions of Incidental Uses.

9.4.4 Construction Type

The BACH is of Type IIB noncombustible, unprotected construction as permitted by IBC. Column Protection is not required (UFC 4-211-01).

9.4.5 Height and Area Limitations

The BACH is an unlimited area building of Groups B, F, and S use occupancies in accordance with IBC §507.5. There are more than 60 feet of clearance around the BACH and the facility will be sprinkler-protected throughout.

9.5 WATER SUPPLY FOR FIRE PROTECTION

Provided fire pump test data from October 2022 testing indicates that two 1,500-gpm fire pumps are located west of the BACH location in Buildings 2119 and 2123. These fire pumps each produced 115 psi at 1,500 gpm and are connected to a 12-inch underground fire line running north-south along the west side of South Douglas Boulevard. These fire pumps are supplies from an adjacent ground water storage reservoir reported to be of 400,000-

Tinker Air Force Base, Oklahoma 65% Design Submittal

Design Analysis - 104 gallon capacity. The connect fire main is similarly fed by multiple other fire water reservoir/pump arrangements.

Based on the fire pump performance information and hydraulic estimations, the existing water supply will meet the expected BACH fire water demand.

Information about the fire suppression design is in a later section.

The new 12-inch fire main will be routed under South Douglas Boulevard to the Bomber Campus to supply the BACH sprinkler risers. It remains to be determined if a check valve or isolation valve (in a vault) should be provided to permit a higher pressure or isolated zone in the Bomber Campus in the future when the Central Utility Plant fire water tanks / pumps are installed.

In accordance with UFC 4-211-01 site fire hydrants will be supplied from the domestic water underground utility lines. Hydrants will be spaced at maximum 300-foot intervals around the BACH, but not in front of hangar bay door openings; since the hangar bay doors are more than 360 feet wide, a hydrant must be placed at either side of both openings. The minimum service size for the fire hydrants will be 6 inches. A shut-off valve will be provided at each hydrant. One of the new fire hydrants will be located within 150’ of the fire department connection to the sprinkler risers for both buildings.

9.6 FIRE SUPPRESSION SYSTEMS AND OTHER EXTINGUISHING

EQUIPMENT

9.6.1 Sprinkler System Design

An automatic wet pipe sprinkler system will be used to protect the BACH. The maximum floor area supplied by one sprinkler system riser shall be designed in accordance with NFPA 13 §8.2 System Protection Area Limitations. The sprinkler system will be designed per UFC 3-600-01. The discharge requirements for non-storage occupancies must be in accordance with Table 9-3, unless otherwise noted in UFC 3-600-01 and/or UFC 4-211-01. Storage sprinkler protection will be in accordance with NFPA 13, and UFC 3-600-01.

UFC 3-600-01 Table 9-3 only covers ceiling heights up to 100 feet, however the highest deck elevation in the BACH is expected to be more than 109 feet above the finished floor. In the absence of protection criteria for roofs higher than 100 feet, the 100-foot protection solution is applied throughout the hangar bay area. This protection is designed to provide an Extra Hazard density in the form of twelve K-25.2 sprinklers designed to flow with at least 7 psi at the hydraulically most remote sprinkler. This protection is designed to flow for at least 90 minutes. There are no inside hose stations and outside hose streams are not factored in the calculation as the hydrants are to be connected to the domestic water system (not the fire water utility). The admin and support areas are protected as Light or Ordinary Hazard occupancies in accordance with UFC 3-600-01 as indicated on the fire protection drawings.

Sprinkler protection design for the shops and storage areas around the perimeter of the hangar are based on the commodities (hazardous materials)

Refer to the associated sections in this document for additional information on FRCS.

11.2 DESIGN CRITERIA

Refer to separate Section GENERAL, Subsection "General Design Guidance and Criteria" located at the beginning of this Design Analysis narrative.

11.3 CONTROL SYSTEMS

11.3.1 Fire Alarm/Mass Notification System (FAMNS)

All building management control systems (BMCS) and the fire alert/suppression/mass notification system will include a comprehensive cybersecurity design. The fire suppression/mass notification system communicates to the central alarm center via Monico BT-XM radio transceiver/receiver operating on a narrowband frequency and will be fully compatible with the Monico D-21 Central Receiving System. The vendor will be responsible for ensuring the controls installed meet or exceed Unified Facilities Criteria 4-010-06 or current policy.

The anticipated level of work is to prepare the building level controls and provide documentation to support the System Owner. Applying cybersecurity to the fire alert/suppression/mass notification system must occur at the following levels per the UFC-04-010-06 Change 1:

• Level 0 (Sensors and Actuators)

• Level 1A (Non-IP Controllers)

• Level 2A (IP-Based Controllers)

• Level 3 (Wireless)

The vendor will not be responsible for the authority to operate (ATO). There is no proposed traditional IT involved in the project for the Fire Alarm. The vendor’s responsibility is to deliver a hardened system in accordance with the UFC and UFGS.

The proposed Confidentiality, Integrity, and Availability (CIA) of the system is Confidentiality – Low, Integrity – Low, Availability – Moderate.

The proposed system owner is to be Tinker Air Force Base Civil Engineering, unless confirmation from the government is received that another system owner exists.

11.3.2 Heating Ventilation and Air Conditioning

All building management control systems (BMCS) will include a comprehensive cybersecurity design. DDC is managed via an operator workstation, via the ethernet, which is connected to the base-wide AFCEC Community of Interest Network Enclave (COINE) network. The base currently has two HVAC systems on their ATO, Honeywell EBI and Tridium ABS. The Bomber Agile Common Hangar will be managed through the Honeywell EBI system. All mechanical equipment will be BACnet compatible and connected through the Honeywell EBI DDC system. The DDC will be capable of connection to the EMCS via the CE VLAN. The vendor will be responsible for ensuring the controls installed meet or exceed Unified Facilities Criteria 4-010-06 or current policy. The anticipated level of work is to prepare the building level controls and provide documentation to support the System Owner. Applying cybersecurity to the DDC/HVAC must occur at the following levels per the UFC-04-010-06 Change 1:

• Level 0 (Sensors and Actuators)

• Level 1A (Non-IP Controllers)

• Level 2A (IP-Based Controllers)

• Level 4B (Workstations)

The vendor will not be responsible for the ATO. The vendor’s responsibility is to deliver a hardened system in accordance with the UFC and UFGS.

SECTION 12 - ENERGY CONSERVATION

12.1 EXECUTIVE SUMMARY

The United Facilities Criteria (UFC) requires new construction to achieve a 30% energy cost savings over an ASHRAE 90.1-2019 Appendix G baseline while also being Life Cycle Cost Effective (LCCE). The design team analyzed several energy efficiency measures (EEMs) for both energy cost savings and LCCE using energy modeling and Life Cycle Cost Analysis (LCCA) software.

The EEMs analyzed included envelope, electrical, lighting, service hot water, HVAC, and onsite renewable energy improvements. The results of the analysis include recommendations for bundling EEMs together for a design that meets the UFC requirements.

12.2 APPLICABLE CODES AND STANDARDS

UFC 1-200-02 requires commercial buildings to meet the requirements of ASHRAE 90.1-2019 Appendix G and be LCCE. ASHRAE 90.1-2019 Appendix G Performance Rating Method (PRM) requires project designs to have a proposed Performance Cost Index (PCI) that meets or exceeds a baseline Performance Cost Index target (PCIt).
