1. INTRODUCTION

Jensen Hughes has prepared this fire protection design analysis, as required by Unified Facilities Criteria

3-600-01 for the renovation of Buildings FC550 & FC555 at MCB Camp Lejeune, North Carolina. This design analysis summarizes the applicable fire safety and building code requirements.

2. PROJECT DESCRIPTION

The project involves the renovation of Barracks FC550 & FC555 which are existing three-story buildings, with each floor having a gross footprint area of approximately 16,580-sf. The primary use of Buildings

FC550 & FC555 is as a residential facility. The buildings consist of three stories of sleeping rooms with exterior balconies and exterior stairs at each end. In the middle of each floor is a central core consisting of lounge rooms, laundry, and an interior stairway. The building has a sloped combustible roof over the existing flat concrete roof. There are two adjacent Mechanical Buildings for FC550 (FC550A & FC551) and two adjacent Mechanical Buildings for FC555 (FC555A & FC556). Mechanical Buildings FC550A, FC551, FC555A & FC556 will be classified as separate buildings.

Buildings FC550 & FC555 are currently protected throughout with fire alarm and sprinkler systems. The fire protection work involves the demolition of the existing fire alarm and sprinkler systems; the installation of a new wet-pipe fire sprinkler system per NFPA 13R throughout the buildings; and a new fire alarm/mass notification system to coordinate with the repairs to the facility. The existing sprinkler system provides coverage throughout each floor except for the bathroom within the sleeping rooms and the office areas. There is no sprinkler system within the attic.

The project involves extensive repair and replacement of existing building systems including: the replacement of all doors and windows, repainting of the exterior, replacement of bathrooms, expansion and reconfiguration of existing laundries, replacement of all interior finishes, replacement of mechanical, electrical, and fire protection systems throughout. The scope of work can be defined as a modification to the facility in accordance with LSC Section 43.2.2.1.3.

The building is constructed of non-combustible construction apart from the existing combustible roof.

Many of the interior walls have a 1-hr fire-resistance rating, and based on an assessment of the construction of the exterior load bearing walls, these have a minimum 2-hr fire-resistance rating, hence the construction type of the building can be considered as Type III-B.

3. DESIGN ANALYSIS

Edition; and o NFPA 101, Life Safety Code, 2024 Edition (LSC); and

• The Architectural Barriers Act (ABA).

2. Other UFC and NFPA codes and standards apply to the project and are referenced in these documents.

3. Buildings FC550 & FC555 will undergo modifications as defined by UFC 3-600-01 and the LSC and as such is required to comply with the requirements for new construction [LSC §43.5.1.3].

4. UFC 3-600-01 generally requires construction issues to comply with IBC criteria and life safety/egress issues to meet the requirements of the LSC. Conflicts between the IBC and the LSC related to fire resistance ratings are required to comply with the LSC criteria and applicable provisions of the UFC code [UFC 3-600-01 §3-2 & §3-3].

5. Buildings FC550 & FC555 will be protected with a NFPA 13R residential sprinkler system. IBC code allowances for fully-sprinklered buildings have not been applied for increases in building area and height. LSC code allowances for fully-sprinklered buildings have been applied for increases in travel distance and decreases in interior finish ratings.

3.1. CLASSIFICATION OF OCCUPANCY

1. The building consists of a barracks and necessary supporting facilities. The building is classified per the IBC as a Group R-2 building [IBC §310.3]. For LSC compliance, the building will be classified as a dormitory occupancy [LSC §6.1.8.1.4].

2. Rooms or spaces used for assembly purposes (e.g. lounges) and which have a design occupant load of fewer than 50 persons will be classified as residential (Group R-2) occupancies. All assembly-use spaces will have an occupant load of less than 50 persons and will be classified as residential (Group R-2) occupancies.

3. Special hazard areas including mechanical, utility, electrical, telecom, and storage areas are considered incidental to the main occupancy. These areas are required to be protected in accordance with LSC Section 8.7.1 and LSC Table 28.3.2.2.2.

3.2. CONSTRUCTION FEATURES

3.2.1. Minimum Construction Type

1. The minimum construction type of a structure is required to comply with the fire resistance requirements and fire area limitations in UFC 3-600-01 and the IBC. The minimum construction type of a building is typically based on the height, area, occupancy, open street frontage, and automatic sprinkler protection provided in the building.

Fire Protection Design Analysis –Final Submittal p. 5

2. The building is non-combustible construction apart from the existing combustible roof. For Type

III-B construction, the following height and area limitations in Table 1 apply to the building for verifying the minimum required construction type.

3. Building area increases for frontage must comply with IBC Section 506.3. The building perimeter has open space greater than 20-ft for 100% of it. The minimum open space is 23.5-ft between

Buildings FC550 & FC551 and 29.25-ft between Buildngs FC555 & FC555A. Based on the percentage of building perimeter and the minimum open space, the frontage increase factor is

0.5 [IBC Table 506.3.3].

4. The buildings can be classified as Type III-B construction.

3.2.2. Construction Requirements

1. The required fire resistance ratings of building structural elements as specified in IBC Table 601 are provided in Table 2 below for Type III-B construction:

Table 2: Required Resistance Ratings of Structural Elements

Building Element IBC Type III-B

Structural frame, including columns, girders, trusses a 0-hr

Bearing walls, exterior 2-hr

Bearing walls, interior 0-hr

Non-bearing walls, exteriorb 0-hr

Non-bearing walls, interiorc 0-hr

Floor construction, including supporting beams and joists 0-hr

Roof construction, including supporting beams and joists 0-hr a The structural frame is considered to be the columns and the girders, beams, trusses and spandrels having direct connections to the columns and bracing members designed to carry gravity loads.

b Based on IBC Table 705.5 for a fire separation distance of 30-ft or more.

c Not less than the fire resistance required by other section of the code.

2. Any load bearing exterior walls require a two-hour rating for Type III-B construction. An examination of the structural drawings prepared for the original construction of the building

Fire Protection Design Analysis –Final Submittal p. 6 indicates that there is a system of load bearing beams and columns along the face of the sleeping rooms; however, the end walls of the building are load bearing walls. These walls consist of 8-in thick CMU blocks with 4-in thick brick veneer. The bricks are noted as being solid with solid grout between all brick units.

a. A standard unfilled 8-in CMU block has an equivalent thickness of 4.0-in [National Concrete

Masonry Association TEK 7-1A Table 2]. IBC Table 722.3.2 lists the fire-resistance rating of concrete masonry walls based on the equivalent thickness; a 4.0-in equivalent thickness CMU wall provides a 1.75-hr fire-resistance rating (based on calcareous or siliceous gravel being the least fire-resistant aggregate). A standard brick has an equivalent thickness of 3.6-in. IBC

Table 722.4.1(1) lists the fire-resistance rating of brick walls based on the equivalent thickness; a 3.6-in brick wall provides a 1-hr fire-resistance rating. The total fire-resistance rating of the wall can be calculated using IBC Equation 7-7, which results in a 4.4-hr fire-resistance rating.

Ra = (R1

0.59 + R2

0.59)1.7 = (1.750.59 + 10.59)1.7 = 4.4-hr

3. Various interior CMU partitions require 1/2-hr and 1-hr ratings as identified in Section 3.2.4. These partitions are 8-in thick CMU blocks.

a. A standard unfilled 8-in CMU block has an equivalent thickness of 4.0-in [National Concrete

Masonry Association TEK 7-1A Table 2]. IBC Table 722.3.2 lists the fire-resistance rating of concrete masonry walls based on the equivalent thickness; a 4.0-in equivalent thickness CMU wall provides a 1.75-hr fire-resistance rating (based on calcareous or siliceous gravel being the least fire-resistant aggregate).

4. The existing roof coverings consist of the following:

a. FC550 – Shingles over felt.

b. FC555 – Standing seam; underlayment is unknown.

3.2.3. Exterior Fire Exposure

1. The requirements for providing fire resistance-rated exterior walls and openings are based on the fire separation distances between buildings and the occupancy groups within the buildings.

2. The fire separation distance is defined as the distance measured from the building face to the closest interior lot line, to the centerline of a street or public way, or to an imaginary line between two buildings on the same lot [IBC §202].

3. The fire separation distance is a measure of the separation to a point along a line between buildings, not the actual distance between buildings. The fire separation distance is measured at right angles from the face of the wall.

4. Once the location of the lot line is established, all future provisions must be based on this lot line and applied to both buildings. Where the lot line is not parallel to the exterior wall of a building, the required fire resistance rating may vary along the building side.

Fire Protection Design Analysis –Final Submittal p. 7

5. For building sides not fronted by a street, the fire separation distance is measured to an imaginary line between the buildings assuming the buildings are located on the same property (i.e., an interior lot line).

6. Where a new building is erected on the same lot as an existing building, the code requires the assumed property line to be located such that the existing building complies with exterior wall and opening protection criteria [IBC §705.3].

7. The fire-resistance rating of exterior walls with a fire separation distance of 10-ft or less shall be rated for exposure to fire from both sides [IBC §705.5].

8. The exterior walls are required to extend the full height of the building and be constructed to remain in place for the duration of time indicated by the required fire-resistance rating [IBC

§705.6].

9. The code requirements for the fire-resistance rating and exterior wall openings are provided in

Table 3.

10-ft ≤ FSD < 30-ft 1 0

FSD ≥ 30-ft 0 0

10. The distance between Building FC550 and Mechanical Building FC551 is 23.5-ft. This provides a fire separation distance from Mechanical Building FC551 to the imaginary property line of 3.5-ft and a fire separation distance from Buildings FC550 to the imaginary property line of 20-ft.

a. The wall of Mechanical Building FC551 is required to have a 1-hr fire resistance rating.

b. The wall of Building FC550 along XO Office 112 and CO Office 114 is required to have a 1-hr fire resistance rating.

11. The distance between Building FC550 and Mechanical Building FC550A is greater than 40-ft. This provides a fire separation distance from Mechanical Building FC550A to the imaginary property line of 10-ft and a fire separation distance from Building FC550 to the imaginary property line of at least 30-ft. There is no fire resistance rating required for the exterior walls of Buildings FC550

& FC550A based on the fire separation distance.

12. The distance between Building FC555 and Mechanical Building FC555A is 29.25-ft. This provides a fire separation distance from Mechanical Building FC555A to the imaginary property line of

4.25-ft and a fire separation distance from Buildings FC550 to the imaginary property line of 25-ft.

a. The wall of Mechanical Building FC555A is required to have a 1-hr fire resistance rating.

Fire Protection Design Analysis –Final Submittal p. 8

b. The wall of Building FC555 along Kitchenette 116, XO Office 118, and Sleeping Room 120 is required to have a 1-hr fire resistance rating.

13. The distance between Building FC555 and Mechanical Building FC556 is greater than 40-ft. This provides a fire separation distance from Mechanical Building FC556 to the imaginary property line of 10-ft and a fire separation distance from Building FC555 to the imaginary property line of at least 30-ft. There is no fire resistance rating required for the exterior walls of Buildings FC555

& FC556 based on the fire separation distance.

14. The openings of the exterior walls of the buildings are required to comply with IBC Table 705.8

[IBC §705.8.1].

a. The 1-hr fire-rated exterior wall of FC550 is permitted to have 45% unprotected openings.

b. The 1-hr fire-rated exterior wall of FC551 is not permitted to have unprotected openings.

c. The 1-hr fire-rated exterior wall of FC555 is permitted to have 70% unprotected openings.

d. The 1-hr fire-rated exterior wall of FC555A is not permitted to have unprotected openings.

3.2.4. Barriers and Partitions

3.2.4.1. Vertical Exit Enclosures

1. Exit stairways and utility shafts connecting less than four (4) stories are required to be enclosed with 1-hr fire-resistance rated construction [LSC §8.6.5]. LSC Section 7.1.3.2.1(2) requires the supporting construction for fire barrier walls, including shaft enclosure walls, to be protected to afford the required fire-resistance rating of the fire barrier supported. Thus, the supporting construction for all 1-hr fire-resistance rated walls must have a minimum 1-hr fire-resistance rating except 1-hr fire barriers for incidental use areas required by LSC Section 8.7.1 and LSC Table

28.3.2.2.2 [LSC §8.2.3.3].

3.2.4.2. Special Hazard Areas

1. A special hazard area is an area or room having a degree of hazard greater than that normal to the general occupancy of the building. LSC requires separation and/or protection by automatic fire suppression systems for these spaces [LSC §8.7.1.1].

2. Special hazard areas will be protected with automatic sprinklers. The following spaces as shown in Table 4 are required to have fire barriers or non-fire-rated smoke partitions in accordance with

LSC Section 8.7.1.2.

Table 4: Incidental Use/Special Hazard Area Requirements

Occupancy Required Fire

Barrier Separation Code Reference

Fuel-fired Heater Rooms 1-hr LSC Table 28.3.2.2.2

Laundry Rooms > 100-sf 1-hr LSC Table 28.3.2.2.2

3.2.4.3. Sleeping Room Separations

1. Each sleeping room within a suite shall be separated from other sleeping rooms by walls and floors

Fire Protection Design Analysis –Final Submittal p. 9 constructed as fire barriers having a fire-resistance rating of not less than 1/2-hr [LSC §28.3.7.2].

One door from a sleeping room to the shared bathroom within each suite is required to have a fire-resistance rating of not less than 20-min and shall not be required to be self-closing

[LSC §28.3.7.3].

2. Separation of the exterior exit access balcony is not required since dead end conditions do not exist on the balcony [LSC §7.5.3.3]. Doors from the sleeping rooms to the exterior exit access balcony are required to be self-closing and self-latching [LSC §28.3.6.2.3].

3.2.5. Opening Protection

1. Openings in fire resistance rated barriers and walls are required to comply with applicable IBC

[Table 716.1(2)] and LSC [Table 8.3.3.2.2] criteria. Per UFC 3-600-01, fire protection rated doors shall comply with NFPA 80 and must be listed by Underwriters Laboratories, approved by Factory

Mutual, or listed by a nationally recognized testing laboratory.

2. The fire-protection ratings for door and window openings in fire barriers and fire and smoke partitions are provided in Table 5 [LSC Table 8.3.3.2.2; IBC Table 716.1(2)].

Table 5: Required Fire-Protection Ratings for Openings

Type of Assembly Required Fire-Protection Rating

1-hr fire barriers enclosing shafts and exit enclosures 1-hr

Other 1-hr fire barriers and 1-hr fire-resistance rated exterior walls 3/4-hr

1/2-hr fire barriers 1/3-hr

3.2.6. Concealed Spaces

2. Draftstopping and fireblocking are required in accordance with IBC Section 718 for combustible concealed spaces based on the anticipated construction type.

3. Fireblocking is required to be installed to cut off concealed draft openings (both vertical and horizontal) and to form an effective barrier between floors, between a top story and a roof or attic space.

a. As the majority of the building is non-combustible, construction fireblocking is not required.

4. Draftstopping shall be provided in attics or concealed roof spaces of Group R-2 buildings with three or more sleeping units. Occupancies in Group R-2 that do not exceed four stories the attic shall be subdivided by draftstops into areas not exceeding 3,000-sf or every two sleeping units, whichever is smaller. Draftstopping shall be installed above, and in line with, sleeping unit separation walls that do not extend to the underside of the roof sheathing above.

a. Given that the sleeping units are fire separated by a concrete ceiling from the combustible attic space, the provision of draftstops in-line with the sleeping units below does not appear to be a reasonable requirement.

Fire Protection Design Analysis –Final Submittal p. 10

3.3. HVAC SYSTEMS

1. Air handling, HVAC, and exhaust systems, including fire/smoke dampers, are required to comply with NFPA 90A except as modified by UFC 3-600-01 [UFC 3-600-01 §28-1.1].

2. Fire dampers are required in ductwork or air transfer openings that penetrate fire resistance rated assemblies. NFPA 90A permits the deletion of fire dampers in fully ducted penetrations of 1-hr fire resistance-rated partitions.

a. Class I Dynamic Fire Dampers are required at duct penetrations of the Mechanical Room floors.

3. Smoke dampers are required in systems with a capacity greater than 15,000-cfm to isolate the air-handling equipment, including filters, from the remainder of the system in order to restrict the circulation of smoke, except where air-handling units are located on the floor they serve and serve only that floor, or air-handling units are located on the roof and serve only the floor immediately below the roof [NFPA 90A §4.3.10.2].

4. The installation of duct detectors is required to comply with NFPA 90A. Smoke detectors listed for use in air distribution systems shall be located as follows:

a. Downstream of the air filters and ahead of any branch connections in air supply systems having a capacity greater than 2,000-cfm [NFPA 90A §11.4.2.1(1)].

b. At each story prior to the connection to a common return and prior to any recirculation or fresh air inlet connection in air return systems having a capacity greater than 15,000-cfm and serving more than one story [NFPA 90A §11.4.2.1.(2)].

5. Plenum spaces may be used as part of an air handling system where the plenums comply with

NFPA 90A.

3.4. INTERIOR FINISH MATERIALS

1. Interior walls and ceiling finishes are required to comply with UFC 3-600-01 Section 8-1 which requires wall and ceiling finishes, and movable partitions to conform to the requirements of the

LSC. The LSC restricts the use of certain materials as interior finishes on walls and ceilings based on the flame spread rating and smoke development rating of the material. Interior wall and ceiling finishes shall be classified in accordance with ASTM E-84.

2. The interior finish materials shall be grouped in the following classes, based on their flame spread rating and smoke developed rating [LSC §10.2.3.3]:

• Class A – Flame spread 0-25, smoke developed 0-450

• Class B – Flame spread 26-75, smoke developed 0-450

• Class C – Flame spread 76-200, smoke developed 0-450

3. Table 6 summarizes the interior finish requirements for Buildings FC550 & FC555 [LSC Table

4. The codes also specify requirements for interior floor finish and floor covering materials. Interior floor finish materials shall be classified in accordance with NFPA 253, Standard Method of Test for

Critical Radiant Flux for Floor Covering Systems Using a Radiant Heat Energy Source as follows

[LSC §10.2.7.4]:

• Class I – Critical radiant heat flux ≥ 0.45 W/cm2

• Class II – Critical radiant heat flux ≥ 0.22 W/cm2

5. There are no additional interior floor finish requirements for fully sprinklered Dormitory

Occupancies [LSC Table A.10.2.2, Note 6].

3.5. MEANS OF EGRESS

1. Means of egress are defined as continuous and unobstructed paths of travel in a building that led to a street, alley, or other parcel of land open for public use. Examples of means of egress include, but are not limited to, doors, corridors, ramps, or stairs. Means of egress may include both interior and exterior components. Means of egress are required to comply with the LSC.

3.5.1. Occupant Load

1. The design occupant load for an area or space is calculated based on the anticipated use of the space and the appropriate factors specified in LSC Table 7.3.1.2. The following occupant load factors are applicable to the project:

• Sleeping Rooms – 2 persons per room

• Residential use, including laundry and related spaces – 200-sf/person

• Assembly (less concentrated with tables and chairs) – 15-nsf/person

• Offices – 150-sf/person

• Mechanical/electrical equipment rooms – 500-sf/person

2. The building is being designed with an occupant load of 2 persons per sleeping room.

3. Table 7 summarizes the design occupant loads for the building per floor.

3.5.2. Number & Capacity of Means of Egress

1. The minimum number of exits required from an area or building is based on the design occupant load [LSC §7.4.1.2]. A minimum of two exits is required from areas with an occupant load of less than 500-persons. A single exit is permitted for areas where the exit access is less than the allowable common path of travel [LSC §28.2.4.2].

2. Based on the calculated design occupant load for the building, the building is required to have a minimum of two exits from each floor. The First Floor has an exit from each sleeping room and mechanical rooms. The Second and Third Floors are each provided with two remote exterior exit stairs and one interior exit stair.

3. The capacity of the means of egress is required to comply with LSC Section 7.3. The egress capacity of the exits must be sufficient to accommodate the calculated occupant loads. For level components (e.g., doors) and ramps, the egress capacity is based on 0.2-in/person for doors and

0.3-in/person for stairs [LSC Table 7.3.3.1].
