1 General Description

1.1 Purpose of Report

The purpose of this Design Analysis (DA) is to provide the technical basis of design for the B2606 Fire Alarm Repair project at Mountain Home Air Force Base (MHAFB), Idaho.

The design is in general accordance with the Unified Facilities Criteria (UFC). This report presents the best available information at the time of publication.

1.2 Scope of Report

The scope of this report covers the project from inception through the 95% design per the statement of work (SOW) provided by MHAFB, dated 26 January 2025, and HDR

Engineering, Inc.’s (HDR) technical assumptions. The SOW and HDR’s technical assumptions are included in Appendix A. This report captures design information and direction used during the project design process.

This project will provide 35%, 65%, 95%, 100% final design drawings, design analysis, project specifications, and cost estimate.

1.3 Background

Building 2606 (B2602) features a single-story Sanctuary with Narthex, Lobby, Choir Loft and Mechanical Mezzanine, a single-story Fellowship Hall with kitchen and mechanical room, and a single-story Chaplaincy Administrative Office, located at MHAFB, with the earliest portion of the building reportedly constructed in the mid 1940’s, with recent renovations of the Fellowship Hall having been completed within the past five years. The

Sanctuary, Fellowship Hall, and Chaplaincy Administrative Offices measure approximately 6,670 sq. ft., 2,655 sq. ft., and 5,070 sq. ft., respectively. The building’s combined area measures approximately 14,395 gross sq. ft. The Sanctuary has a posted occupancy of 348 persons, while the Fellowship Hall’s occupancy load is calculated to be approximately 258 persons.

The existing fire alarm system is obsolete, and replacement parts are no longer available. Accordingly, critical system maintenance has been deferred. Given the lack of replacement parts and deferred system maintenance, false alarms are reported to be frequent, resulting in MHAFB Fire Department making emergency runs to false alarms. A complete fire alarm system replacement is required to provide reliable system operation and eliminate false alarms.

Additionally, the existing fire alarm system lacks provisions for a mass notification system, as required for occupied buildings having more than 10 full-time employees. The replacement system will include an autonomous mass notification system.

1.4 Project Description

1.4.1 Description of Work

The project will replace the existing failing fire alarm system with a new addressable fire alarm / mass notification system (FA/MNS) throughout the entire building.

1.4.2 Architectural

Architectural work is limited to supporting the FA/MNS replacement. Anticipated architectural work includes limited patching and painting as well as the replacement of acoustical ceiling tiles impacted by the FA/MNS replacement.

Firestopping for through- and membrane-penetrations will also be required for conduit penetrations and back boxes installed at fire-resistive and smoke-rated construction.

1.4.3 Structural

No structural work is required.

1.4.4 Mechanical

Mechanical work supports the FA/MNS replacement, specifically replacing existing duct smoke detectors with new addressable duct smoke detectors and the installation of control interfaces to shut down mechanical systems in accordance with National Fire

Protection Association (NFPA) 72 and applicable mechanical codes.

New duct smoke detectors will be installed on the supply-air ducts of air handling units

(AHUs), package units (PUs), and roof top units (RTUs), exceeding 2,000 cubic feet per minute (CFM), where capable of spreading smoke beyond the room of origin. The mechanical systems will be interfaced with the FA/MNS to shut down AHUs, PUs and

RTUs upon detection of smoke.

Additionally, supply and return air ducts having fire/smoke dampers installed in fire/smoke-rated construction will be equipped with duct smoke detectors. Fire/smoke dampers will be interfaced with the FA/MNS system to close dampers upon detection of smoke.

1.4.5 Fire Protection

Fire protection work consists of replacing the existing fire alarm system with a new addressable FA/MNS. Additionally, fire protection will include installing interfaces to automatic sprinkler systems.

The new FA/MNS will be installed in accordance with NFPA 72, UFC 3-600-01, UFC 4-

021-01, and the Architectural Barriers Act (ABA).

The new FA/MNS will be sole sourced as a Silent Knight EVS Series FA/MNS. The new

FA/MNS will communicate with the MHAFB AES IntelliNet 2.0 base-wide monitoring system. The FA/MNS will be equipped with a compatible radio transmitter and VHF omni-directional antenna.

19 December 2025 | 3

Fire suppression work supports the FA/MNS replacement, specifically removing existing sprinkler system water flow and valve tamper switches from the exiting fire alarm system and connecting them to the new FA/MNS.

1.4.6 Electrical

Electrical work supports the FA/MNS replacement, specifically providing dedicated 120 volts alternating current (VAC) and electrical ground for surge protection devices.

2.1 Site Planning

The scope of work will be performed within the existing B2606. Site planning is not applicable to this project. Figure 2-1 depicts the location of B2606.

Figure 2-1. Vicinity Map

2.2 Utilities

The project will not impact existing utilities.

2.3 Architectural

The primary architectural scope is limited to replacing ceiling tiles where ceiling-mounted devices are removed during demolition and replacing ceiling tiles damaged by the contractor during installation of conduit and back boxes.

Additional architectural scope will include patching and painting surfaces impacted by demolition and installation activities on gypsum board ceilings and walls to match surrounding areas.

19 December 2025 | 9

Finally, firestopping and joint sealants will be installed at through- and membrane-penetrations of fire-rated and smoke-rated construction. This project will not repair existing through- and membrane-penetrations not associated with the fire alarm system.

The contractor will protect walls, floors, carpeting, equipment and furnishings during demolition, patching and painting, to the fullest extent possible. This includes the use of clean drop cloths, plastic film and frequent debris removal during construction. Dust control measures shall be employed for all operations creating dust. All areas will be thoroughly cleaned and vacuumed by the contractor prior to installation of smoke detectors. Furnishings and equipment moved by the contractor to accommodate both demolition and new work will be returned to their original position by the contractor.

2.3.1 Ceiling Mounted Devices

The project will have minimal impact on existing lighting, air distribution, or ceiling-mounted devices. To gain access to ceiling spaces to install conduit and back boxes for the FA/MNS, the contractor may have to temporarily move ceiling-mounted devices. No acoustical ceiling grid removal is anticipated. The contractor will return ceiling-mounted devices to their original locations.

2.3.2 Roof Systems

The project will not impact existing roofing systems.

The exterior mounted omni-directional antenna will be mounted on exterior walls or at roof eaves but will not be attached to or penetrate roof coverings.

2.3.3 Ceilings

Individual existing suspended acoustical ceiling tiles will be removed, as required, to complete the demolition and installation of the FA/MNS. New replacement tiles will match existing tiles. Where the existing ceiling tiles have been discontinued, the contractor will identify a donor room from which tiles will be removed and used in other building areas to match existing tiles. All tiles within the donor room will be replaced in their entirety so that all tiles within the donor room match. No ceiling grids will be removed, replaced, re-leveled, or painted except to repair damage caused by demolition and construction.

Ceiling openings resulting from the removal of ceiling-mounted fire alarm devices will be patched, taped/floated, textured, and painted to match surrounding areas.

Cutting access openings within the existing gypsum board ceilings may be required to accommodate the installation of the new FA/MNS. The contractor will cut, patch, tape/float, texture, and paint to match surrounding ceiling areas. Where more than one opening is cut within any room, the entire ceiling will be painted from wall to wall.

2.3.4 Walls

Wall openings resulting from the removal of wall-mounted fire alarm devices will be patched, taped/floated, textured, and painted to match surrounding areas.

Cutting access openings within the existing gypsum board walls may be required to accommodate the installation of the new FA/MNS. The contractor will cut, patch, tape/float, texture, and paint to match surrounding areas. Where more than one opening is cut within a room, the entire wall will be painted from corner to corner and floor to ceiling.

2.4 Structural

The project will not impact existing structural design.

2.5 Mechanical Systems

Existing duct-mounted smoke detectors will be removed and new addressable duct-mounted smoke detectors, compatible with the FA/MNS, will be installed within the supply-air ducts of AHUs, PUs and RTUs exceeding 2,000 CFM, where capable of spreading smoke beyond the room of origin. Addressable control modules and relays will be installed adjacent to HVAC equipment and variable frequency drives (VFDs) and arranged to shut the units down upon detection of smoke.

Where ducts penetrating fire-rated barriers are equipped with fire/smoke dampers, new addressable duct smoke detectors will be installed within 5 feet of the damper assembly.

Addressable control modules and relays will be installed to close the damper upon detection of smoke within the dedicated duct detector. The installation of new fire/smoke dampers is not part of the project scope.

Duct detectors, shut down interfaces, and interlocks will be configured in accordance with the IMC, NFPA 72, and NFPA 90A/B.

Existing ATFP emergency HVAC system shut down stations will remain. Emergency

HVAC shut-down controls will not be integrated into the FA/MNS LOC.

The new FA/MNS control equipment will not appreciably add to the building’s heat load.

2.6 Sustainability

Sustainable design is limited to material use and specification for this limited-scope project.

2.7 Life Safety and Fire Protection Systems

2.7.1 Life Safety Code Analysis

This project is defined as an Alteration Level I in accordance with IEBC. An Alteration

Level I includes the removal and replacement or the covering of existing materials, elements, equipment, or fixtures using new materials, elements, equipment, or fixtures that serve the same purpose (IEBC §602.1). IEBC also defines an Alteration Level I exceeding 50 percent of the building area as an Alteration Level III (IEBC §604.1).

Additionally, this project is defined as a Renovation in accordance with NFPA 101.

Renovations include the replacement in kind, strengthening, or upgrading building elements, materials, equipment, or fixtures that do not result in a reconfiguration of the building spaces within (NFPA 101 §43.2.2.1.2).

19 December 2025 | 11

NFPA 101 §43.4.1.4 states that a Renovation shall not make the building less conforming with other sections of the code (UFC 3-600-01 and NFPA 101) than it was before the renovation was undertaken.

This project will have no impact on occupancy classification, building occupancy loads, means of egress, fire suppression systems, and fire department access.

This project is also defined as a Major Project in accordance with UFC 3-600-01 §2-1.20.

UFC 3-600-01 §1-7.1.1 requires that a code analysis be performed for all Major Projects.

This code analysis applies only to the project’s scope (i.e., installation of a new

FA/MNS). Accordingly, this code analysis is limited to defining the code path required to achieve a compliant FA/MNS.

Building 2606 is a Mixed-Use / Non-Separated Occupancy, featuring Group A-3

Assembly and Group B Business Occupancies in accordance with IBC §303.4 and

304.1. NFPA 101 additionally defines the building occupancy as non-separated

Assembly and Business Occupancies. Accessory occupancies include Light Hazard

Storage, Mechanical, and Electrical rooms.

UFC 3-600-01 §9-18.5 requires that fire alarm and detection be provided in accordance with NFPA 101. NFPA 101 Chapters 12 and 13 apply to New Assembly Occupancies and Existing Assembly Occupancies respectfully and NFPA 101 Chapters 38 and 39 apply to New Business Occupancies and Existing Business Occupancies, respectively.

In the case of a fire alarm system replacement the alarm and detection requirements for a New Assembly and New Business are applicable. Specifically, the Detection and Alarm requirements of NFPA 101 §12.3.4 for the Assembly spaces (Sanctuary and Fellowship

Hall) and NFPA 101 §38.3.4 for the administrative office spaces are applicable to this new Fire Alarm / Mass Notification System.

Initiation of the FA/MNS will be by manual and automatic means (i.e. manual pull stations, smoke detectors and heat detectors) in accordance with NFPA 101 §12.3.4.2 and 38.3.4.2. Activation of waterflow devices from the partial sprinkler system will also initiate the FA/MNS. MHAFB has requested full area detection (smoke and heat detection) be provided throughout the building as a voluntary addition to the required annual fire alarm system. This proposed system exceeds the requirement of UFC 3-600-

01 §9-18.5.

Safety interfaces such as HVAC shut-down, fire-smoke damper closure and fire door closure will be provided in accordance with NFPA 72, NFPA 80 and NFPA 90A/B.

Occupant notification will be compliant with Public Mode (NFPA 72 §18.5) within common spaces. Audible appliances will sound with an SPL of at least 15 dB above the ambient sound level or 5 dB above the maximum sound level having a duration of at least 60 seconds, whichever is greater, when measured 5ft. above the floor in accordance with NFPA 72 §18.4.4.1.

Because B2606 occupancy load exceeds 10 full-time DoD personnel, mass notification is required throughout to provide timely notification to building occupants, in accordance with UFC 4-010-01 §2-3.5. Accordingly, the requirements of UFC 4-21-01 are applicable in addition to the Life Safety requirements identified in UFC 3-600-01 and NFPA 101.

The contractor will satisfy the design requirements of UFC 4-021-01, including the installation of a Local Operators Console (LOC), as well as speaker placement to ensure that voice intelligibility is achieved throughout.

MHAFB is equipped with an existing wide area mass notification system (WAMNS), also referred to as a “Giant Voice” system. MHAFB does not desire the interfacing of the new in-building mass notification system with the Giant Voice system.

2.7.2 Means of Egress

The project will have no impact on the means of egress. Additionally, all means of egress will be maintained during construction.

2.7.3 Passive Fire/Smoke Protection features

All through- and membrane-penetrations through fire-rated barriers and smoke partitions will be performed in a manner that maintains the fire-resistance and smoke ratings. All abandoned penetrations resulting from the existing fire alarm conduit demolition will be closed and/or sealed to restore fire-resistance and smoke ratings. All firestopping materials and systems will require the use of UL Solutions or FM Global approved materials.

Additionally, any access openings cut into ceilings and walls to accommodate the

FA/MNS installation will be repaired in a manner that maintains the fire-resistance and smoke ratings.

2.7.4 Interior Finishes

All required patching and painting of ceilings and walls will maintain current ceiling and wall finish classifications.

2.7.5 Fire Alarm and Mass Notification

The existing fire alarm system will be demolished in its entirety and replaced by a new code compliant, addressable FA/MNS. MHAFB has designated the Silent Knight

6820EVS Series Fire Alarm and Mass Notification System model for installation for all future FA/MNS installation projects. Auxiliary control equipment includes the Silent

Knight EVS-RCU remote command center (Local Operators Console), Silent Knight EVS

Series Remote amplifier, available in both 50-watt and 125-watt models, and Silent

Knight 5895 intelligent remote power supplies. Datasheets for the above-mentioned control equipment are provided in Appendix C.

MHAFB currently monitors existing fire alarm and FA/MNS with a Monaco D-21 Base-

Wide Monitoring System with primary and secondary receivers located within the

Command Post of Building 1501 (B1501) and at the MHAFB Fire Station (B206), respectively. MHAFB plans to remove the Monaco D-21 monitoring system from service in a phased approach, with all new FA/MNS systems being monitored by the new AES

Intellinet 2.0 Base-Wide Monitoring System currently under procurement. Presumably, the new AES Intellinet 2.0 monitoring system will be operational prior to the B2606 fire alarm repair project going out to bid.

19 December 2025 | 13

The contractor will be required to provide all necessary hardware, software, interfaces, and programming to establish remote monitoring of the FA/MNS system installed for this

B2606 project. This includes AES 7707P-88-ULP-M IntelliNet 2.0 Fire Subscriber transmitter, omni-directional antenna, LMR-400 coaxial cable, surge suppressor and antenna mounting hardware.

The control equipment for the new FA/MNS system will be relocated from its present location due to the fact that the existing Mechanical Room is not environmentally controlled. The new control equipment will be installed within the large conditioned

Mechanical Room located adjacent to the Fellowship Hall kitchen. Dedicated 120 VAC will be provided for the new FA/MNS system in accordance with UFC 3-520-01.

The new FA/MNS will be equipped with manual pull stations located at all building exits.

Photoelectric beam smoke detectors will be installed within the Sanctuary. The

Chaplaincy Administrative Office will feature addressable heat detectors within offices and storage rooms and addressable smoke detectors within the corridors. Unsprinklered portions of the Fellowship Hall will be equipped with addressable heat detectors. Spot smoke detectors will be installed over system control equipment, including the main

FMCU, remote amplifiers and remote power supplies.

The new FA/MNS will monitor the valve tamper switches and water flow switches of the existing automatic sprinkler system currently serving only the Fellowship Hall Kitchen and Mechanical Room. Addressable monitor modules will be installed to monitor the backflow preventer tamper switches and water flow switch.

Electromagnetic door holders will be provided for the existing fire doors and will be configured to release doors upon the initiation of any fire alarm detection device.

The new FA/MNS will provide complete occupant notification via strobes and speakers/strobes within all common spaces, and with weatherproof high output speakers located immediately outside of principal building entrances.

Mass Notification Messages will be distributed throughout the buildings as a single zone.

Mass Notification pre-recorded and live messages will be initiated by the Local Operators

Consoles located within the Sanctuary Lobby. The LOC will be equipped with a thumb latch allowing any building occupant to initiate MNS messages.

Per MHAFB request the following voluntary additions exceeding UFC 3-600-01 and

NFPA 72 requirements will be provided:

a. All exterior weatherproof speakers are upgraded to weatherproof speaker strobes.

b. Full area detection where automatic sprinkler protection is not provided consisting of both area smoke and area heat detection.

c. Photoelectric beam smoke detectors within the sanctuary, The contract documents will demonstrate the design intent, with the final design and development of shop drawings delegated to the contractor. The contractor will complete the design, in accordance with UFGS Div 28 31 76 specifications. The contractor’s shop drawings and calculations will be prepared by an individual having a minimum

Certification of National Institute for Certification in Engineering Technologies (NICET)

Level III in Fire Alarm Systems. The contractor will also secure the services of a Qualified

Fire Protection Engineer (QFPE), as defined by UFC 3-600-01 §2-1.16.2. Prior to submittal to the Government, the contractor must submit drawings, calculations and material submittals to the QFPE for review, in accordance with UFC 3-600-01 §9-18.2.

After thorough review and application of the QFPE’s review stamp the design may be submitted to the Government.

Contractor qualifications include minimum 5-years' experience installing similar systems as well as being factory trained on the Silent Knight EVS series system. Additionally, the contractor is required to develop a detailed and comprehensive testing and acceptance plan. Pretesting includes megger testing, loop resistance testing as well as audibility and intelligibility testing to ensure that audio messages are audible and intelligible throughout the building.

2.7.6 Fire Suppression

Only the Kitchen and Mechanical Room of the Fellowship Hall are equipped with automatic sprinkler protection. Other than interfacing the FA/MNS with the existing valve tamper and water flow switches, this project will not impact on the existing automatic sprinkler system.

Building 2606 features multiple construction types ranging between Type III to Type V.

UFC 3-600-01 §9-7.2.1.3 requires all single-story buildings with Type III, IV or V construction types and a gross building area exceeding 5,000 sq. ft. to be equipped with automatic sprinkler protection throughout. B2606 does not currently meet this requirement. This Pre-Existing / Non-Conforming condition will remain after this project is completed.

2.7.7 Fire Department Access

The project will have no impact on Fire Department Access.

2.8 Electrical

2.8.1 Electrical System

The electrical scope includes removing the existing dedicated 120 VAC power for the existing fire alarm system control equipment, as well as any high-voltage mechanical system interfaces to allow for the demolition of the existing fire alarm system.

Additionally, the electrical scope includes installing dedicated 120 VAC for the new

FA/MNS control equipment to include main FMCU, remote amplifiers, remote NAC power supplies, LOC, etc. Dedicated 120 VAC power shall be provided in accordance with UFC 3-520-01. Where the systems loads require more than one dedicated 120 VAC circuit, a dedicated sub-panel having no less than six circuits will be installed adjacent to the FA/MNS control equipment. Breakers will be factory-painted red and breaker locks will be installed. Each piece of control equipment shall have its respective 120 VAC power circuit prominently displayed on the exterior of each enclosure, using engraved labels.

19 December 2025 | 15

The electrical scope also includes the installation of Surge Protective Devices (SPDs) for

120 VAC circuits. SPDs will be installed within a separate enclosure adjacent to FA/MNS control equipment. The electrical grounding system will be extended as required to provide suitable low resistance ground for SPDs.

2.9 Cybersecurity

This section assumes a baseline level of understanding of the Risk Management

Framework (RMF) and, more specifically, the Unified Facilities Criteria (UFC) for

Cybersecurity of Facility-Related Control Systems (FRCS), UFC 4-010-06. The design, relative to the FRCS incorporated herein, is tailored to the requirements of the UFC. This criterion supports the RMF, which outlines the DoD’s process for securing information systems (IS) and modern-day industrial control systems (ICS) and devices.

Although the UFC’s application will not result in the issuance of an authorization-to-operate (ATO), implementation of the resulting secure configuration baseline onto FRCS, which operates at Platform Information Technology (PIT) Levels 1 or higher, will produce a system that is appropriately adapted for a favorable authorization decision. FRCS, which operates at PIT Level 0, will be identified as well. However, security will take the form of physical access control because, while they will not communicate over the network, devices may cause physical damage. An example of this would be a valve that is left in the “open” position. Where these devices and/or conditions are identified, such will be documented within the Control Systems Description Section below.

Coordination among client representatives, other AE disciplines, and the cybersecurity designer is necessary to ensure that essential details are adequately captured as early in the design process as possible. Even so, early submittals may lack substantive details.

Late-stage deliverables, however, with the selection of the starting CCI list and confirmation of the C-I-A Impact Level(s), will yield a tailored set of risk mitigation measures and edited UFG 25 05 11 Specifications for incorporated FRCS, with the designer’s guidance for implementing relevant security controls.

Control systems are categorized based on the impact of loss to a system’s confidentiality, integrity, and availability (C-I-A) on the organization's mission, which may be classified as High, Moderate, and Low. These levels are determined jointly by the

System’s Owner (SO) and Authorizing Official (AO) for the respective control system. In the event C-I-A impact levels are not provided and a facility classification is identified, levels may be derived from a default list of FRCS. If neither the C-I-A impact levels nor facility classification is provided by the client, the designer may make assumptions based on UFC 4-010-06 guidance and the rationale for any hypotheses will be recorded within this document.

The project includes the design and execution of cybersecurity requirements for B2606’s

Fire & Life Safety (FLS) equipment. The existing Fire Alarm Panel at B2606 is antiquated and is to be replaced with a new Fire Alarm and Mass Notification System.

2.9.1 Applicable Codes and Standards

The design is based on, but not limited to, the publications and codes listed in Section

1.6 of this Design Analysis.

2.9.2 Organizational Design Criteria

Selection of Security Controls for this project will use the Cybersecurity Design Process as outlined by UFC 4-010-06, Section 3-1.2, Definition of “Organization,” unless otherwise indicated. The Security Controls will be tailored for the Contractor to implement according to this Organization’s Design Criteria.

Per the Statement of Work (SOW), submittals are to be in accordance with U.S. Air

Force criteria. Therefore, the final accepting Organization for this design for all Facility

Related Control Systems (FRCS) identified below shall be AIR FORCE.

For this reason, the additional organizational design requirements listed in Section 1.6 of this Design Analysis are considered to be applicable.

Network Architecture Design Basis

The Air Force has not formalized a Platform Enclave approach. And, although the Civil

Engineering (CE) Community of Interest Network Enclave (COINE) is deployed at most sites, the accreditation does not extend to all CE control systems. Therefore, for this project, all control systems, their sub-systems, and associated devices are designed according to UFC 4-010-06 Appendix C, Figure C-1, 5-Level Control System

Architecture, as indicated in the figure below.

Control System Description

Fire & Life Safety (FLS) Systems

The scope for the FLS systems includes the replacement of the existing Fire Alarm

System with an addressable Fire Alarm and Mass Notification System. The Fire Alarm and Mass Notification System will transmit trouble, supervisory, and alarm signals to the existing Fire Alarm Reporting Systems (FARS) at the MHAFB Fire Department via an

AES 7707P-88-ULP-M IntelliNet 2.0 Fire Subscriber transmitter. The AES Intellinet 2.0 base-wide monitoring system is currently under procurement and will constitute the

FARS.

Table 2-2 FLS Control System Reference Table

2.9.3 Control Correlation Identifiers (CCIs)

In response to RFI 004, the Government, on 17 July 2025, informed the AE that “…at

Bldg 2606, any cybersecurity designs are not applicable.” However, upon analysis of

DAFGM 2024-32-01 and UFGS 25 05 11, which are applicable directives that MHAFB follows, it was determined that the Fire Alarm/Mass Notification System, specifically the

FMCU, requires coverage under UFC 4-010-06. Therefore, the Cybersecurity Design

Process, outlined in UFC 4-010-06 Section 3-1.3, is to be followed to mitigate risk to the system and the enclave IAW DoD RMF Process. As such, UFGS 25 05 11 and associated CCIs have been tailored for the FLS and included within the design due to the nature of the Fire Alarm and Mass Notification System’s PIT Level 1 communications.

The requirements of the final CCI tailoring process are in accordance with UFC 4-010-06

Section 3-1.3. This part of the Cybersecurity Design process is coordinated with the other Discipline Leads throughout the Design of the Project.

2.9.4 Concept Design

The Mountain Home FRCS Cybersecurity Installation Design Guideline is based on the

2017 version of UFC 4-010-06, which contains fewer requirements than the updated version, released on 10 October 2023. To align with current standards, the 2023 version of UFC 4-010-06 was used as the design basis for the FLS Security Control Set, CCIs, and UFGS Division 25 tailoring to ensure that FRCS Cybersecurity complies with the latest requirements.

The following table lists the UFGS Specification required for the control system identified and its associated CCI List, which can be found in the appendices listed.

Based upon the Control System identified as indicated in Control System Description

Section, the table below summarizes the contractor and government boundaries for provision and installation of equipment and control system configuration. Delineation of

Roles and Responsibilities are as follows:

19 December 2025 | 21

Gov = Government – The Government is responsible to execute

Con = Contractor – The Contractor is responsible to execute

N/A = Not Applicable – The execution of these responsibilities is not applicable

Cor-N = Coordinate-New - If a new system is being added locally and will be connected to an existing base-wide Monitoring and Control (M&C) system, then the government is responsible for reviewing all existing M&C software that will be modified to provide available or unused addressing, naming, and configuration information to the contractor to facilitate the integration of new equipment, within the scope of the project. This is to avoid conflicts between the new equipment being added with the existing system equipment. The Contractor is responsible for providing the device and system information to the government to allow the government to add the new equipment and configuration information of the new equipment in the project to the existing M&C system software. The contractor is responsible for any deconfliction and resolution of integrating the new equipment that might be discovered during the integration process.

As of October 2025, the materials for 95% Design Issuance, relevant to the

Cybersecurity Design for all identified FRCS, have been provided as stated.

3 Economic Summary The cost estimate will be provided under a separate cover.

4 Hazardous Material Survey IHR conducted a hazardous materials inspection focused on asbestos containing materials (ACM) and lead-based paint (LBP). ACM is defined as containing greater than one percent asbestos. LBP is defined as quantities greater than 1.0 mg/cm2. The inspection was conducted on 20 September 2018. The complete asbestos and lead inspection report is in Appendix D.

ACM inspection was performed on cove base and mastics, drop ceiling tiles, drywall and wallpaper, duct mastic on HVAC system, and carpet mastics in rooms and hallways.

Black mastic under vinyl floor tile in the fellowship hall contained greater than one percent asbestos. A 10-day notification must be filed with the EPA prior to any renovation requiring the removal of asbestos above the threshold of 160 square feet or 260 linear feet. Al ACM should be abated by a qualified contractor utilizing AHERA trained workers.

No LBP was found on surfaces in the chapel kitchen and fellowship hall.

5 QFPE Final Design Review and Certification The QFPE reviewed the complete 100 percent design drawings and specifications and documented in writing that the design complies with UFC 3-600-01 §1-7.3. The design compliance document is provided in Appendix E.
