1.3 RLB Policy, Standards, and Guidelines

USARCENT has authority delegated from Assistant Chief of Staff for Installation Management (ACSIM) to purchase RLBs and can re-delegate the authority to other General Officer level Commands. Approval is required for each Relocatable Building purchase for a specific site and unit to fulfill defined requirements. As such all U.S. Army RLB acquisitions for the CENTCOM/USARCENT Area of Responsibility (AoR) must come through the USARCENT Engineers for approval. Further guidance is available for Army Forces (ARFOR’s) and Area Support Groups (ASGs) to facilitate acquisition upon request.

2.0 Requirements

RLBs will be manufactured off site and delivered to the CENTCOM AoR. The RLB envelopes will be capable of being complexed as a single or two story structure by adding or removing envelopes as needed or where needed in a scalable manner. RLBs will be rapidly deployable, air transportable, and simple to ship, they will also be easily sustainable, low maintenance, utilize redundant parts, and require minimal spare parts. They will be designed and composed of materials to mitigate issues with termites, rot, mildew, mold and warping. No stucco, gypsum board, or magnesium oxide panels will be utilized in any of the RLBs.

2.1 Structural and Sizing

Structural Requirements will be defined in 4 RLB envelopes (which will then be defined as RC II, RC III, RC IV, and RC V). Although there are similarities to risk categories the criteria for these envelopes are defined as such to meet the maximum requirements based on any potential utilization. This will standardize the number of possible variations with packages available based on intended use of the RLB. The envelopes must have certified engineer stamped drawings for all 4 varieties. All structural components will be clearly marked with the corresponding RC stamp to ensure only like envelopes are complexed for any future applications. An identification plate is also required for the structure to indicate the model, serial number and year of production. Consideration should be given to reduce the weight of the components for ease of assembly.

Minimum gross square footage for a building envelope will be 160 sq ft (typically 8’x20’). The maximum gross square footage for a single RLB envelope will be 640 sq ft (typically 32’x20’).

The number of RLB envelopes complexed together for a single story will not exceed 6 sections which limits the greatest single story size to 3840 sq ft (typical RLB envelope sizes are 8’x20’, 10’x20’, 12’x20, and 32’x20). Exceptions are outlined in the DFAC/Kitchen Package.

2.1.1 RC II Rated

RC II rated RLB envelopes will be the standard unless otherwise specified. Seismic calculations will utilize IE 1.0, snow calculations will meet IS 1.0, ice calculations will meet Ii 1.0, wind load will meet or exceed 110 mph/177 kph, earthquake load will not exceed Ss 0.55 and S1 does not exceed 0.13. Uniform floor load will meet 6.0 kPa/125 psf with a concentrated load standard of 1.33 kN/300 lbs and roof load will meet a concentrated load of 1.33 kN/300 lbs.

2.1.2 RC III Rated

RC III rated RLB envelopes are typically standard for the following styles of structure: any occupancy that exceeds 250 personnel, boiler rooms, battery charging rooms, generator rooms, power plants, aircraft utility shops, and storage for drugs, paint, or oil. Seismic calculations will meet IE 1.25, snow calculations will meet IS 1.1, ice calculations will meet Ii 1.25, wind load will meet or exceed 115 mph/185 kph, earthquake load will not exceed Ss 0.55 and S1 does not exceed 0.13. Uniform floor load will meet 9.6 kPa/200 psf with a concentrated load standard of 1.33 kN/300 lbs and roof load will meet a concentrated load of 1.33 kN/300 lbs.

2.1.3 RC IV Rated

RC IV rated RLB envelopes are typically standard for the following style of structures: communications, operations, fire, police, air traffic, hospital/clinics, emergency shelters, manufacturing assembly area, storage of building materials, and industrial repair areas. Seismic calculations will meet IE 1.5, snow calculations will meet IS 1.2, ice calculations will meet Ii 1.25, wind load will meet or exceed 115 mph/185 kph, earthquake load will not exceed Ss 0.32 and S1 does not exceed 0.08. Uniform floor load will meet 12.0 kPa/250 psf with a concentrated load standard of 1.78 kN/400 lbs and roof load will meet a concentrated load of 1.33 kN/300 lbs.

2.1.4 RC V Rated

RC V rated RLB envelopes are typically standard for the following style of structures: air defense artillery sites, dishwashing rooms, electrical or engine overhaul shops, dry provision or hardware storage, refrigeration units, or critical national defense assets. Seismic calculations will meet IE 1.0, snow calculations will meet IS 1.5, ice calculations will meet Ii 1.5, wind load will meet or exceed 140 mph/225 kph, earthquake load will not exceed Ss 0.32 and S1 does not exceed 0.08. Uniform floor load will meet 14.4 kPa/300 psf with a concentrated load standard of 2.22 kN/500 lbs and roof load will meet a concentrated load of 1.33 kN/300 lbs.

2.2 Finishes

External RLB surfaces will be moisture and corrosion resistant and should not attract destructive pests. External RLB components will be #33446 in color per Federal Standard 595C to maximize reflection of solar radiation within the desert while also blending with existing background colors. Federal Standard 595 #33446 is further defined by the color coordinates for hex triplet #B49D80, RGB 180/157/128, CMYK 30/40/60/0, HSV 33.5/28.9/70.6. Color of the RLBs will be imbedded in the outer material so as to negate having to re-paint them. Baked on paint is acceptable if the exterior skin is metal and will not rust or corrode to require repair and repainting. The paint coating utilized will be low absorptivity with high surface emissivity. UFGS 09 90 00 “Paints and Coatings for Minimum Dry Film Thickness” (DFT) ensure the typical applications of paints, varnishes, primers, enamels, undercoats, and other coatings are to a minimum dry film thickness of 0.038 mm (1.5 mil) each coat when not using galvanized finishes. Finishes similar to Kynar 500 (http://www.kynar500.com/en/product-information/kynar-500-fsf-pvdf/) are acceptable. The paint coating utilized will be low solar absorptivity with high surface emissivity.

2.3 Thermal Efficiency

RLBs will have a minimum thermal efficiency of R-17+ (floor), R-15+ (walls) and R-17+ (roof). Designs that overlap and/or interlock panels is preferred to reduce or eliminate thermal bridging at seams. They will also have a minimum fire resistance of Type II non-combustible in accordance with the International Building Code (IBC).

2.4 Environmental

All equipment will be designed to endure the USCENTCOM/USARCENT Area of Operation (AOR) environment. The USCENTCOM/USARCENT AOR spans from Egypt to Kazakhstan, and Pakistan to Yemen, while encompassing all the middle-east nations. Characteristics of this environment include rugged terrain, extremely high temperatures, high humidity, sand/dust storms, extreme shifts in temperature and heavy but infrequent rainfall. RLBs should be able to withstand inclement weather to include; but not limited to, exposure to water/rain and ambient temperatures from -10 degrees C to 55 degrees C and storage temperatures up to 70 degrees C. Maximum ambient temperature is expected to be 65 degrees C in storage. Little or no shade will be available so the proposed design will be able to withstand even higher surface temperatures of 65 degrees C due to absorption of solar radiation within a desert environment.

2.5 Acoustics

All panels will have acoustic deadening properties. See Figure 4-2 in UFC 3-101-01 “Sound Isolation” for sound transmission class (STC) standards. These standards have been lowered for the RLB envelopes. Walls, partitions and floor/ceiling assemblies separating dwelling units and sleeping units from each other or from public service areas shall have a sound transmission class of not less than 40, or not less than 35+ in field testing for air-borne noise. Penetrations or openings in construction assemblies for piping; electrical devices; recessed cabinets; bathtubs; soffits; or heating, ventilating or exhaust ducts shall be sealed, lined, insulated or otherwise treated to maintain the required ratings. This requirement shall not apply to entrance doors; however, such doors shall be tight fitting to the frame and sill. Overall the RLBs will target a STC rating of 35+ in field testing. STC is an established way to average how much sound is stopped by something. STC ratings are used for windows, doors, walls and most building materials. Interior wall panels shall contain no voids.

2.6 Rain Mitigation

RLBs and all of the components will be able to withstand heavy but infrequent rainfalls of less than 3 inches while remaining water tight throughout the useful lifespan of the RLB. Due to outstanding drainage issues in theater standing water of less than 6 inches could be expected after heavy rainfalls, therefore after the structure is leveled the interior floor of RLBs will be located at least 7 inches above ground level. The roofing system and roof edges will be water tight and capable of shedding water to the exterior of the structure to ensure runoff. The roofing system will be designed and panels overlapped to be impermeable to wind driven water between the roofing panels. If an architectural flashing system is utilized as the primary means for rain and moisture control, then the roof edging will be finished with Type I Non-Sag silicone based sealant (ref para 2.10) as a secondary means for rain and moisture control to further control condensation and beading of water permeating insulated roof or wall panels to reduce the possibility of mold or mildew.

2.7 Toxicity

Use of recyclable non-toxic free of volatile organic compounds (VOCs), persistent organic pollutants (POPs), and formaldehyde materials is required to ensure life, health, and safety to building occupants and ecological system of the local environment. The absence of hazardous materials eliminates any special handling requirements and disposal procedures.

2.8 Fasteners

All fasteners will be galvanize coated to reduce corrosion. All panels, connections, and fasteners will be suitable for all environments, require no maintenance, and be non-binding in cold or hot desert conditions.

2.9 Exterior Seal

The RLBs will provide a tight seal to prevent water infiltration and minimize air-infiltration to include all seams. If necessary a water tight seal will be provided around the perimeter, adjoining areas, and seams of the exterior wall panels. The seal should be able to last a minimum of 15 years and be able to be reattached and reused. Adhesive based seals are not preferred. Foam or rubber weather proof strips placed between panels before connection to provide a seal system similar to a car door or a refrigerator are preferred. The connection of the two envelopes together must keep pressure to ensure a water/air tight seal.

2.10 Sealant Type I NS Silicone

If necessary due to structural design, all RLBs will include enough Type I Non-Sag silicone based sealant to allow for 3 liberal coats for joints and substructures as detailed in the assembly guide. Sealant should remain flexible, mildew resistant, water and proof with a life expectancy of at least five years. Sealant will be applied correctly on the outside in accordance with the assembly instructions to provide a weather seal and continuous bead with a second application on the exterior. Sealant will also be applied on the inside as a third and final seal to prevent seepage on the inside.

2.11 Foundation and Structure

RLB envelope design will be suitable for installation in a desert environment on semi-level surfaces such as a compacted sand gravel mix with minimum site preparation. They will be capable of being leveled and situated on existing, minimally prepared, roughly graded, packed sand/gravel surfaces. RLBs will not require a foundation and will utilize a structural leveling system with a +/- 3” adjustability on each footer. Varying thickness weather proof shim plates large enough to span 2 footers will be provided for multiple RLB envelopes erected as one structure. Shim plates will not be any variation of wood or wood based product. The footers will be able to withstand and widely disperse the weight of the structure, lockers, equipment, and soldiers while withstanding occasional heavy rainfall. All horizontal and vertical joints will be seamless in appearance and tolerant to variations in square and leveling as envelopes are complexed to a larger structure.

2.12 Transportability

The base of the RLB envelope will have a steel channel with sub floor top-plate installed where the fork lifting points will be located. The steel plates will run the length of the forklift points to prevent damage to the subfloor if the RLB is handled with short forks versus long forks of the forklifts. Four lifting points will be provided on the base and top corners of any envelope design to accommodate structural integrity for crane lifting operations and allow movement by a WRTCH container handler or similar.

2.13 Ease of Installation

RLBs envelopes must be easily assembled by highly trained military personnel with no special experience or training in assembling RLBs while also being ruggedized to withstand rough handling during assembly/disassembly. A single RLB envelope will be portable, scalable, and allow for rapid assembly/disassembly of no greater than 192 man-hours, +/- 64 man-hours with an 8 person crew for a single RLB envelope regardless of envelope size while using a minimal set of hand tools with nothing larger than a ladder. Each RLB structure will ship with one set of hand tools per envelope of which the structure is comprised. When complexing multiple envelopes as a larger two-story structure material handling requirements i.e. forklifts, scissor-lifts, etc. should be kept to a minimum other than the equipment necessary for safety precautions.

2.14 Flexible Configuration

RLB design will utilize wind load cross bracing that doesn’t restrict the complex-ability of the structure in any horizontal direction to facilitate flexibility for open floor plan layouts. When complexing multiple RLB envelopes the walls can be removed to have larger rooms without the wind load cross bracing unnecessarily separating the rooms. When configured in a multi-story arrangement the wind load bracing will not be utilized across the ceiling. Loss of vertical space when in a multi-story arrangement is unacceptable. All UFC requirements to include seismic and wind load standards will still be met.

2.15 Durability

The RLBs will be capable of being assembled, disassembled, and re-assembled at least three times without degradation to functional use and provide a minimum useful lifespan of 15 years.

2.16 Finishing Kits

If necessary for a finished appearance RLBs will include a color matched finishing kit with vented pre-painted 18 gauge galvanized steel skirting for the base of the exterior and finish covering for any interior structural members to include appropriately fire rated material for any gaps through fire rated walls. The skirting shall not have any gaps and exterior finish kit must secure the area below the RLB to the surface. The exterior finish kit for the base of elevated RLB envelopes will include 2 access doors (6’ width minimum) with hasp and lock to allow access below the RLB. The RLB interior will be completed with a color matched finishing kit to provide an overall finished appearance to the interior while hiding and protecting cables (electrical and communication) that run along support members. Skirting needs venting to allow air movement to prohibit mold growth under the RLB due to trapped moisture

2.17 General Wall and Door Layout

When complexing multiple envelope assemblies to a single structure vestibules will be integrated in the design at each entrance point. Vestibules will not be utilized on emergency exits.

All RLBs configurations will have a minimum of two main points of egress. RLB envelopes procured as a system with the intent of complexing to a larger structure to meet a user requirement will identify the specific door layout required. Exterior walls will be replaceable with door panel components to further customize the RLB envelope at the user level. Replacing or changing a single wall panel should not exceed 4 man hours.

Doors will utilize a system to automatically close in order to minimize cooling/heating loss. Doors on the main entrances will open to the exterior and have cypher locks (exception billeting package paragraph 3.3.3). 6 keys will be provided per door. RLB must have standard 36” wide entry ways and a minimum hallway width of 1.219 m (48 in.) with a minimum height of 1.96 m (77 in.). There must not be any tripping hazards that would impede entering or exiting the RLB. Specifically, the threshold of all doors must be level with the rest of the RLB. The main entry will be capable of being secured and the locking device will be releasable from both the interior and exterior of the RLB.

Emergency egress exit standards will be adhered to as outlined in this document. All emergency egress doors will have panic bars installed on the interior of each door and the doors will swing outward. The emergency egress will be in a wall other than the wall of the main entry and be capable of being secured internally. As necessary for an intended use an alternate egress can be designed as a door or whole-body access hatch with a minimum opening of 66 by 76.2 cm (26 by 30 in.). If the hatch is secured from the interior of the RLB it must allow for quick exit.

Two utility rooms will be integrated in each complexed RLB envelope structure. The utility rooms will be air conditioned and heated with a 30 amp service to accommodate a communications server stack. The utility rooms must be large enough and have ample air exchange to allow for continuous operation of the server stack in either utility room.

RLB areas will be configured with floor to ceiling modular internal wall divider system to provide internal complexing flexibility. The usable interior height of the RLBs will be at least seven feet or higher. The usable interior height of the structure shall not be reduced or interfered by any structural support such as cabling.

Composite wall solutions with an air gap between the exterior and interior wall for energy efficiency are acceptable provided the exterior wall meets all fire code and the RLB structure adheres to all RLB standards.

Each RLB envelope structure will come with a number placard package to allow for proper facility numbering.

2.18 Stairs

Stairways and handrails will conform to industry standards. Stairs for the main points of entrance and exit will be free standing structures that have an adjustability of +/- 3” for a total delta of 6” to prevent tripping hazards at the door and ground level. Although free standing the stair systems are required to have a robust anchoring system to the RLB with appropriate adjustability. The stair system must meet the same structural requirements as the RLB envelope and must be able to be adjusted with standard tools and non-welding procedures during the life of the RLB to assure that the stair system adjustments can be easily made as the RLB settles. Stairs are required for all main entrance and emergency exit doors. The stairs and landing platforms will be painted to match the exterior of the building. Stairs will be finished with a durable non slip surface.

2.19 Two-Story Configurations

The RLB envelopes will be capable of being stacked and interlocked with one another to form structures two-stories in height and included stairways to reach the second floor. Two-story RLBs are intended to be grouped into blocks as required. Structures will allow for shared mezzanine/second story walkways and to minimize the quantity of stairs and reduce cost. Cost saving configurations for access to the second floor of RLBs are encouraged. For instance, using a mezzanine that runs the length of the inside and/or outside of the second floor of the RLBs. If used, internal hallway/external doors will open outward and interior doors/individual room doors will open inwards. Second story doors at fire exit openings must swing outward and not block access to the stairs from the platform. Provide potential configurations for the RLBs to be stacked which maximize operational energy and reduces the logistical and environmental footprints for sustainment of the RLB for 15 years and include the building life-cycle costs analysis (BLCC) with each configuration plan.

2.20 General Electrical

All electrical systems will be implemented in accordance with the latest edition of International Electro-technical Commission (IEC) or British Standard 7671. All electrical materials will bear an IEC/BS/TUV listed marking or will bear a genuine CE factory mark.

2.20.1 Electrical Install Designs

Design electrical systems to meet the needs of the activity and supporting facilities in accordance with this document. At least four empty circuits will be provided for any future upgrades. Electrical installation requirements will be clearly defined in the guides (ref para 2.26) for complexing RLB envelopes to larger structures. If complexing multiple envelopes as a single structure only 1 properly sized electrical main will be utilized to support the intended use of the structure. The electrical main will be located in one of the utility rooms as described in the general configuration (ref para 2.18).

Each RLB area will have receptacles installed so that no point measured horizontally along the floor line of any wall space is more than 1.8m (6ft) from a receptacle outlet. At least one outlet will be placed at locations servicing dedicated loads. All receptacles will be duplex receptacles, Type G (BS1363 standard sockets), 240 volt, 50 Hz and the receptacles will be evenly spaced. The contractor will have no more than six receptacles per convenience receptacle branch circuit to ensure adequate capacity without nuisance tripping from overloads. The contractor will provide ground fault interrupt circuit rated at 30 ma and 40 ms protection on all convenience receptacle circuits. All outlets will be designed so that the ground pin is oriented at the top of the outlet. As per UFC 3-520-01, “Interior Electrical Systems” paragraph 3-6.1.2 (b) office, staff-support spaces, and other workstation locations require two duplex receptacles, one double duplex, or one quadraplex receptacle for each workstation with a minimum of one for every 10ft (3m) of wall space. When less than 10ft (3m) of wall at the floor line, provide a minimum of two receptacles spaced appropriately to anticipate furniture relocations. Any design will limit loads to a maximum of four (4) workstations per 20A circuit.

Bonding jumpers are required on all exposed metal inside the RLB envelope. All junction boxes will be readily accessible through any finishing kits on the interior of the envelope. Ready accessible is defined as capable of being reached quickly for operation, renewal, or inspections without requiring those whom need ready access is requisite to take actions such as to use tools (other than keys), to climb over or under, to remove obstacles, or to resort to portable ladders, and so forth. All switches will be mounted at a height of 48”, are required to come with a grounding mechanism, and light switches shall be located at all room entrances. Every fixed electric motor will have a dedicated isolation switch to provide an efficient means of switching off, readily accessible, easily operated and placed to help mitigate danger.

The interior of the RLB electric service circuit breaker panel will be readily accessible to permit use of data logger device(s) within the panel. Each RLB electrical service panel will have a main disconnect breaker, and adequate over-current protection for each branch circuit in accordance referenced British Standards. Service size for each RLB is RLB dependent, but should be three phase, 230 VAC, 50 hertz (3 Hot + 1 Neutral ref TN-C-S (PME) System in the BS 7671). Exterior waterproof utility boxes will be utilized on the side of the assembly to facilitate a communications access box, and separate electrical input box. One utility box will be a connection point for electrical with IP67 rated style connector. The other utility box will be an empty junction box that leads into the unit for communication cable access. Interior electrical panel will be flush mount, preferably in the hallway or recessed in a beam or column to provide a finished appearance while maximizing utilization of the quick disconnect electrical connectors. All cables will be quick disconnect style, of appropriately size, length, and labeled. Cables will be protected from hazards such as sharp edges when traveling through openings and will utilize a system to present a neat and organized finish. Cable mounting system will ensure secure connection to the walls. Wiring systems encroaching on escape routes shall not be within arm's reach unless they are provided with protection against mechanical damage likely to occur during an evacuation. Flexible cables shall be heavy duty type having a voltage rating of not less than 450/750 VAC or be suitably protected against mechanical damage. Interior panel locations will have a minimum of 36” + for clearance in front of the panel(s) for maintenance. All receptacles will be enumerated to correspond with the circuit in the main circuit breaker panel.

2.20.2 Genuine Equipment Required
