CHAPTER 7: FIRE PROTECTION & LIFE

SAFETY

7.1 Goals and Objectives

As the Fire Protection Engineer (FPE) on this project, Jensen Hughes will provide fire protection and life safety related code consulting to the project team. Additionally, we will serve as the Engineer of Record in the design of fire suppression, fire alarm and notification systems. In this role, JENSEN HUGHES will act as an advisor to the design team on internationally recognized codes and standards as well as pertinent GSA specific code requirements.

We have developed the following project code compliance approach:

● Establish fire and life safety objectives that are acceptable to the GSA and tenant agencies and are consistent with international design practices for similar buildings.

● Based on the established fire and life safety objectives, prepare a fire protection and life safety program that identifies the building features and systems to be incorporated into the design.

● Identify and resolve fire protection and life safety related code compliance issues by discussion with the GSA and coordination with the design team.

7.1.1 Responsibilities

As the FPE on the project team, we are required to be a full participant of the design team for each phase of the project from concept through design, construction, and occupancy. The FPE will perform the following.

Analysis of:

● Building construction (Existing)

If a conflict exists between GSA requirements and the GSA-adopted codes or standards, the GSA requirements take precedence. All such conflicts will be brought to the attention of the GSA project manager as appropriate for resolution.

7.3 General Design Requirements

The Bricker U.S. Building (USCH) is an existing 7 story building with a basement. The work included on this project will not change or impact the existing building construction type, height, area, allowable occupancy types, or primary egress infrastructure. These items are deemed existing to remain and compliant. The design requirements for this project consist of evaluating the new build out design for compliance with overall floor occupant loading in comparison to the available egress capacity, new work egress compliance, existing fire sprinkler system modifications, and existing fire alarm system modifications.

7.3.1 Building Construction

The existing seven-story Bricker USCH is reportedly at least a type 1B construction with a compliant overall building height and area. The new spaces will not changes the allowable occupancy types within the building. Upon completion of this project, Bricker USCH will remain a fully sprinkler protected building.

7.3.2 Occupancy Classifications

The following are the occupancy classifications in the Bricker Building:

● Group B Business – Includes Office Areas

● Group A-3 Assembly – Includes courtrooms, jury commission, library, and large lounges

● Group S-1 Moderate Hazard Storage – Includes storage rooms; secondary use group separated

B 180’ 12 UL

S-1 180’ 12 144,000

S-2 180’ 12 237,000

7.3.3 Occupancy Separations

The building is identified as non-separated mixed use building.

7.3.4 Shaft Enclosures

Shafts enclosures having a 2-hour fire resistance rating are required where floor openings connect four or more stories and may have a 1-hour fire resistance rating when connecting less than four stories.

Per IBC Section 712.1.12 and 1009.3 exception 4, unenclosed stairs connecting not more than 4 stories are permitted when the floor opening between stories does not exceed twice the horizontal projected area of the stairway and the opening is protected by a draft curtain and closely spaced sprinklers per NFPA 13.

One of the two exit stairways in the existing Bricker USCH includes an open stairway interconnecting the 1st through 4th floors. At a minimum, two enclosed exits should be provided for each story of this building. If this is a historic feature of the building, options other than a fire rated enclosure may be acceptable to the GSA.

Outstanding Item: Review options for enclosure of the open stairway in the Bricker USCH and options to remain unenclosed.

7.3.5 Special Separations

Elevator lobbies are existing and to be maintained as smoke resistive.

7.4 Means of Egress

The means of egress for the building will be designed to Chapter 7 of NFPA 101-2021 edition.

7.6 Fire Alarm and Emergency Communication

Systems

The building has an existing Siemens single hardwired, addressable fire alarm and emergency communication system to serve the Bricker Building. The installed fire alarm system present within the Bricker Building is no longer supported by the manufacturer and equipment and the system has reached the end of its useful life and the technology is changing. Fire alarm systems main components for the existing system are typically required to be second hand or aftermarket parts due to the systems age and parts are no longer manufactured for this model of system. We are aware of another GSA project that is scoped to upgrade the fire alarm system to meet the updated codes and GSA standards. It is our understanding that the existing fire alarm system, in its current state, is not able to be modified to incorporate the extensive changes needed for this project. This project shall either anticipated the upgrade of the existing fire alarm system being completed prior to the start of construction for this project as a baseline for our design documents or the fire alarm upgrade shall be incorporated into the first phase of this project. The system will be modified, designed, and installed in accordance with the requirements in NFPA 72, the IBC, GSA PBS P-100, and the GSA fire alarm system specification Section 283101 requirements for new systems. The fire alarm and emergency communication systems is a self-contained, standalone system that functions independently of other building systems. The emergency communication system will provide an automatic voice message in response to the receipt of a signal indicative of a fire emergency. Manual control with the capability of making live voice announcements will also be furnished to provide occupants notification on either a selective or all-call basis. A firefighters emergency communications system is installed in the building and will be modified as needed for this project to maintain its current level of operation. The fire alarm, emergency communication system, and

Page 07-11 firefighter’s emergency communication system control equipment is located on the first floor of the building within the separated control room in the first-floor lobby space. All new fire alarm and emergency communication system power supplies will be supplied with power provided by conditioned power from the emergency power circuits. Secondary power supplies (batteries) will be rated at 150% of the requirements specified by the NFPA 72.

Drawings delineating areas to be classified as Preservation zones with historic finishes will be referenced when coordinating pathways, fire alarm appliances and devices.

All fire alarm signals (i.e., alarm, supervisory, and trouble signals) are automatically transmitted to a supervising station. The communication methods used to transmit signals to the supervising station meet the GSA’s requirements for existing systems. All new fire alarm wiring will be solid copper and installed in conduit. Conduit systems will be rigid metal or electrical metallic tubing, with a minimum inside diameter of 19 mm (3/4 inch) that utilizes compression type fittings and couplings.

The existing fire alarm system in the building will remain fully operational while areas are being renovated. The old fire alarm equipment in renovation areas will be supported and remain operational.

The new fire alarm equipment will be installed and tested but be tagged “NOT IN SERVICE” until the new fire alarm equipment is accepted by the government, then the tags on the new equipment will be removed and tags will be placed on the old fire alarm equipment and will be removed.

7.6.1 Manual Fire Alarm Boxes

Manual fire alarm boxes will be installed in accordance with the requirements in NFPA 72 and the IBC.

7.6.2 Waterflow Switches

Waterflow switches will be installed on each floor and each fire area protected by sprinkler systems. Each waterflow switch will be separately annunciated at the main fire alarm control unit and all required annunciators. Waterflow switches will be installed in accordance with the requirements in NFPA 13, NFPA 72, the IBC, and the manufacturer’s requirements. Zero-time delay water flow switches without time-delay capabilities will be installed where required.

7.6.3 Smoke Detectors

Multi-Criteria Technology Smoke Detectors will be installed in accordance with the requirements in NFPA 72 and the IBC. Smoke detectors will be installed where required to serve fire safety functions such as elevator recall, and door closures for fire/smoke barriers. Area smoke detectors will not be installed in any of the following rooms: mechanical equipment rooms, electrical closets, telephone closets, and emergency generator rooms. Area smoke detectors will be installed specifically for the protection of the fire control unit(s), notification appliance circuit power extenders, and supervising station transmitting equipment. Smoke detection appropriate for the application will be installed in each of the following:

uninterruptible power service rooms, electrical switch gear rooms, transformer vaults, telephone exchanges, and information technology equipment rooms. When smoke detection is installed in rooms having high voltage equipment, the smoke detection will not be installed directly above the high voltage equipment. Duct smoke detectors will be installed to meet the requirements in NFPA 90A. Operation of a duct smoke detector will not activate the fire alarm evacuation signals and will initiate a supervisory signal.

7.6.4 Audible Notification Appliances

Performance, location, and mounting of audible notification appliances will be installed in accordance with the requirements in NFPA 72. The performance of the audible notification appliances will meet the voice intelligibility requirements in each designated acoustically distinguishable space (ADS). The design for achieving the required minimum dBA levels will take into consideration all building construction materials such as carpeting, hard surfaces, walls, doors, etc., and any other materials that can cause sound level attenuation and/or clarity problems in the placement and location of all audible notification appliances.

Fire alarm speakers will be installed in each elevator car and exit stairways; however, they must only be activated to broadcast live voice messages (e.g., manual announcements). The automatic voice messages must be broadcast through the fire alarm speakers on the appropriate floors, but not in stairs or elevator cars. Audible notification appliances located in the vicinity of the systems manual microphone shall be installed and controlled by a separate initiation circuit so that it can be disabled through the systems programming while a live voice announcement is being made to avoid audio system feedback and clear voice transmissions.

7.6.5 Visible Notification Appliances

Placement and spacing of visible notification appliances will be in accordance with the requirements in NFPA 72. Visible notification appliances will be installed only in public and common areas. Public and common areas include public restrooms, reception areas, building core areas, conference rooms, open office areas, and so on. Visible notification appliances are not required to be installed in individual offices.

Visible notification appliances will not be installed in exit enclosures (e.g., exit stairs) or elevator cars. All new visible notification appliance will be labeled with the word “ALERT” in a contrasting factory labeled red or white lettering.

7.6.6 Occupant Notification

Transmission of an alarm signal from any fire alarm system initiation device to notify the occupants throughout the building will be accordance with the requirements in NFPA 72 and the IBC. All alarm signals transmitted from any fire alarm system initiation device will activate the respective building audible and visible notification appliances to notify the occupants. Duct smoke detectors will not activate the fire alarm system notification appliances.

7.6.7 Fire Alarm Notification Strategies for the Building

The fire alarm and emergency communication system modifications will be designed to be able to maintain the systems operation for selective evacuation. Fire alarms in the building will perform a complete evacuation of the building with the “fire evacuation message”. The visible alarm notification appliance circuits will be activated on all floors. L.E.D. visual notification appliances will be specified for the project and high-fidelity audible notification appliances will be specified for the project in all acoustically distinguishable spaces requiring intelligibility levels of 0.7 Sound Transmission Index (STI) or higher.

7.6.8 Survivability

The fire alarm and emergency communication system will be designed to meet the survivability requirements in NFPA 72 where the system is modified. All new circuits, including speaker/audio, SLC, network, and power necessary for the operation of the notification appliances will be protected until they enter the evacuation signaling zone they serve will be protected to meet the requirements of NFPA 72

7.7.4 Post Indicator Valve

No exterior post indicator valves will be provided as part of this project.

7.8 Automatic Sprinkler and Standpipe Systems

In areas that are documented as historically significant spaces, sprinklers will be carefully placed to minimize damage to ornamental materials. Detailed drawings will be developed for architecturally sensitive areas, showing precise sprinkler locations, and finishing notes as necessary to guide proper installation. When possible, sprinklers will be centered and placed symmetrically in relation to ornamental patterns and architectural features defining the space.

Sprinklers and escutcheons will match original architectural surfaces or hardware. Oxidized brass or bronze heads will be specified in deeply colored (unpainted) woodwork. In elaborately decorated ceilings, heads will be specified to be camouflaged by custom coating and omitting escutcheon plates where permissible. In such cases, we understand low-profile, quick-response sprinklers are preferred.

Preservation zone drawings delineating areas with historic finishes will be referenced when coordinating sprinklers.

New automatic sprinklers will be installed throughout the renovated spaces in accordance with the requirements in NFPA 13, the IBC, GSA PBS P-100, and the GSA sprinkler system specifications 213113. Locations that are specifically exempted from being provided with sprinklers by the GSA RFPE, NFPA 13, and the IBC will be separated from adjacent sprinklered rooms or areas by fire barriers having at least a two-hour fire-resistance rating. All sprinkler systems will be wet-pipe sprinkler systems, unless installed in areas subject to freezing. In areas subject to freezing, dry-pipe sprinkler systems, or dry pendent or sidewall sprinklers will be provided. The sprinkler system modifications will be designed using a minimum system design area of 1,500 sq. ft. with no area decreases permitted. Any floor openings are not classified as atriums and are enclosed on the upper level, with the enclosure opening effectively creating a high ceiling. All sprinkler system control valves will be located in accessible spaces and will not be located in above-ceiling spaces. The first floor control valves and water flow switches located above the ceiling in the elevator lobby will be relocated to an accessible location in the stairs that do not intrude into the height and area clearance requirements dedicated for egress. The dry pipe valve in the basement will be replaced when the dry pipe system for the loading dock is reconfigured for the new layouts for this project. No antifreeze sprinkler systems will be used in the buildings. No pre-action-type sprinkler systems will be installed. All new sprinklers will be provided with guards when the sprinklers are installed less than

2.1 m (7 ft.) above the floor, in elevator machine rooms, in elevator pits, in electrical closets, or in electrical equipment rooms. Any new or renovated electrical switchgear rooms or transformer vaults will be provided with separate supervised manual isolation valves and separate water flow switches located outside the protected space in an accessible location.

7.8.1 Types of Sprinklers

All sprinklers will be selected based on the design requirements for the specific hazards within the buildings to provide protection in accordance with the requirements in NFPA 13 and the IBC. Quick response sprinklers will be installed in all spaces except the elevator machine rooms. Extended coverage upright and pendent sprinklers will not be used. Flexible sprinkler fittings will not be used in these building.
