3) Repair Thermal Envelope: The Contractor shall execute a continuous interior thermal envelope retrofit (Metal Building Liner System) on the roof and specified perimeter walls. The installation shall enclose the existing structural purlins and girts to establish a complete thermal break and a monolithic Class-A vapor barrier.

a) Site Preparation and Surface Remediation:

(1) Vapor Barrier Mitigation (Critical HVAC Requirement): Because the interior space will be mechanically air-conditioned (cooled) against the humid exterior climate of IECC Zone 3A, vapor drive will push moisture inward. To prevent condensation from being trapped against the exterior

SOW for PR 012-26 Page 4 of 23 skin, the Contractor SHALL NOT bypass the mitigation step. The Contractor must systematically slit, perforate, or entirely remove the white vinyl facing on the existing 3-inch insulation on both the roof and walls prior to installing the new interior liner system. Failure to defeat the existing vapor barrier will result in immediate rejection of the work.

(2) Steel Cleaning & Rust Remediation: All structural steel contact points (main columns, base angles, eave struts, and door jambs) must be wiped clean of dust, grease, and manufacturing oils using an approved solvent to ensure 100% adhesion of vapor barrier tapes. Any active, flaking rust encountered on the structural steel must be mechanically wire-brushed and treated with a commercial-grade rust-inhibiting primer prior to concealment.

b) High-Reach Equipment & Safety Logistics:

(1) Elevation Requirements: The facility features a 32-foot eave height and an approximate 42-foot roof peak. The Contractor must provide appropriate high-reach access equipment (e.g., articulating boom lifts) capable of safely navigating the 5-foot purlin/girt spacing and reaching all interior elevations without compressing the insulation materials. Field verify all elevations.

(2) Bridge Crane Coordination: The Contractor shall account for the presence of an active overhead bridge crane when planning lift equipment, scaffolding, and installation logistics. If the Contractor intends to utilize the bridge crane as a work platform, they must submit a formal Fall Protection and Lockout/Tagout (LOTO) safety plan to the COR for review and approval prior to the commencement of overhead work.

(3) OSHA Compliance: The Contractor must strictly adhere to all applicable OSHA fall protection and aerial lift safety regulations, as well as USACE EM 385-1-1 requirements.

c) Interior Metal Building Liner System (e.g., Simple Saver or equivalent):

(1) Roof Retrofit Installation (Target Assembly: ~R-29)

i. The Contractor shall install a high-tensile steel banding grid (spaced max 30" on-center) securely fastened to the bottom flanges of the roof purlins.

ii. A continuous, Class-A fire-rated fabric vapor barrier liner shall be stretched taut across the banding grid, completely concealing the purlins from the floor view.

iii. New 6-inch (R-19) un-faced fiberglass batts shall be installed within the purlin cavities above the fabric liner, resting firmly against the existing roof insulation.

(2) Wall Retrofit Installation (Target Assembly: ~R-21)

i. Face-Applied Thermal Break: Because the existing insulation is exterior to the girts, the new 3.5-inch (R-11) un-faced fiberglass and fabric liner shall be installed continuously across the interior face of the 8-inch girts. The insulation shall not be tucked into the girt cavities.

ii. The system shall be supported by vertical steel banding (spaced max 30" on-center), securely fastened to the base angle and

SOW for PR 012-26 Page 5 of 23 eave strut, pulling the insulation and liner drum-tight against the face of the girts.

d) Air Sealing & Mechanical Terminations:

(1) Monolithic Seal: The new fabric liner must create a 100% airtight, monolithic boundary between the conditioned interior space and the unconditioned exterior/structural cavities.

(2) Seams and Penetrations: All fabric liner seams must overlap by a minimum of 6 inches and be continuously sealed with an approved, high-adhesion vapor barrier tape. All penetrations for electrical conduit, HVAC ductwork, or fire suppression pipe drops must be meticulously taped and sealed directly to the penetrating object.

(3) Thermal Bridging Prevention: The Insulation Contractor shall ensure the steel banding and fabric liner are tensioned tightly to pull the insulation firmly against the interior face of the girts and purlins. The structural steel frame must be entirely enclosed within the insulated cavity to prevent the steel from reaching the dew point of the conditioned interior air, which would cause active condensation and corrosion.

(4) Main Column Terminations (Exposed Columns): The main structural I-beam / tapered columns shall remain exposed to the conditioned interior space. The Contractor shall terminate the wall and roof liner systems at each main column. The Contractor must make precise cuts to fit the fabric liner around the column profile, securely seal the fabric directly to the clean steel using approved vapor barrier tape, and mechanically fasten the liner to the column using termination bars or steel banding to ensure a continuous, air-tight vapor seal at every column junction.

(5) Mechanical Fastening: The fabric liner must be mechanically fastened (using metal termination bars or steel banding with self-tapping screws) to all main building column frames, corners, base angles, and the perimeters of all roll-up and pedestrian doors. Relying solely on tape or adhesive for structural terminations is strictly prohibited.

(6) Decommissioning of Gable Exhaust Fans: The facility is being converted to a fully conditioned (HVAC) machine shop. The two (2) existing exhaust fans located in the gable ends shall be decommissioned. The Insulation Contractor shall construct rigid framing within the fan openings, insulate the cavities to a minimum of R-19, and install the continuous fabric vapor barrier over the openings to permanently seal them against air infiltration, ensuring the integrity of the HVAC thermal envelope. Refer to electrical section for demolition coordination of electrical connection of exhaust fan.

(7) HVAC & Ductwork Coordination: The Insulation Contractor shall coordinate with the Mechanical (HVAC) Contractor. Where new HVAC ductwork or source-capture exhaust systems penetrate the thermal envelope, the Insulation Contractor shall construct rigid "picture frames," mechanically fasten the fabric liner to the framing, and provide a 100% continuous vapor seal around the penetrations using approved tape and/or mastic.

(8) Trade Coordination & Phasing (Penetrations): The facility will undergo concurrent mechanical, electrical, and fire suppression upgrades. The

SOW for PR 012-26 Page 6 of 23

Insulation Contractor shall coordinate their installation schedule with all other trades. All major penetrations through the thermal envelope (HVAC ductwork/exhaust, explosion-proof conduit, and fire suppression drops, etc.) must be rough-installed by the respective trades prior to the Insulation Contractor finalizing the fabric liner in those zones.

(9) The Insulation Contractor retains sole responsibility for constructing the rigid framing ("picture frames") around these penetrations and executing the final 100% vapor seal (using approved tape/mastic) connecting the fabric liner directly to the penetrating infrastructure.

e) Obstruction & Infrastructure Integration

(1) West Wall Electrical Infrastructure (Hybrid Approach):

i. Demolished Zones: Coordinate with the Electrical Contractor to install a continuous liner over bare girts where the main panel is removed. The new panel shall be mounted via standoffs penetrating the new liner (penetrations to be taped).

ii. Existing Panels & Dense Conduit (Rigid Box-Outs Required):

Construct structurally sound, rigid framing ("box-outs") to the depth of the new insulation around all remaining active electrical panels and densely clustered, flush-mounted conduit. The fabric liner and insulation shall terminate and be mechanically fastened to these rigid frames, leaving the panels fully accessible to maintain NEC working/cooling clearances. All seams of the box-out shall be 100% sealed with vapor barrier tape. Fiberglass shall not be packed tightly against conduits.

(2) Roof Fire Suppression (Delegated Design Relocation):

i. The fire sprinkler system shall be modified and relocated per the

FPE Delegated Design, ensuring all sprinkler heads are repositioned to sit below the new fabric liner ceiling. As such, large rigid box-outs for sprinkler head clearance are not required.

ii. The Contractor shall install the liner system as a continuous, monolithic ceiling. Where vertical sprinkler pipe drops penetrate the new liner, the Contractor shall make precise, tight circular cuts.

iii. The fabric liner shall be 100% sealed directly to the pipe drop using approved vapor barrier tape and/or tight-fitting penetration collars to maintain the vapor seal.

iv. The Insulation Contractor must coordinate with the Fire Sprinkler Contractor to ensure the fabric liner is penetrated and sealed after the pipe drops are installed, but before the final sprinkler heads and escutcheon plates are attached, ensuring no tape or adhesive obstructs the functional sprinkler components.

4) Modernize Electrical Distribution System:

a) Upgrade Electrical Service:

(1) Demolish existing service conduit and wire back to the point of demarcation with SWEPCO’s commercial power. Coordinate with SWEPCO on point of demarcation and all other incoming service questions.

(1) Primary Hazard: The facility will house a large horizontal gantry mill dedicated to machining aluminum (generating combustible Class D chips/swarf). The mill utilizes a water-soluble coolant (Chemetall Tech Cool 35052 or similar).

(2) FPE Requirement: The Contractor shall retain a Texas-licensed Fire Protection Engineer (FPE) to evaluate the facility per NFPA 13 and NFPA 484 (Standard for Combustible Metals). The FPE must design a dual-

SOW for PR 012-26 Page 9 of 23 suppression strategy that protects the building structure while safely mitigating the risk of water-aluminum reactions at the mill.

(3) Engineering Deliverables: Prior to commencing physical work, the Contractor must submit the following for review and formal approval by the Contracting Officer's Representative (COR) and the Base Fire Chief:

(a) NFPA 484 Compliance Narrative: A formal statement detailing how the rerouted wet system and the localized clean agent system safely interact with the Aluminum hazard.

(b) Stamped Shop Drawings & Hydraulic Calculations: Detailed plans showing the rerouted overhead piping, the new drop locations/elevations relative to the 4:12 fabric liner, along with stamped hydraulic calculations proving required densities are met.

(c) Stamped Structural Engineering Calculations (mounting localized mill suppression system).

b) Overhead Wet System Modifications & Structural Rerouting - To protect the facility structure without risking a water-to-aluminum reaction, the FPE must establish a "water exclusion zone." Note: Due to the operational envelope of an active overhead bridge crane, the construction of a physical "water exclusion canopy" or fixed deflector shield above the gantry mill is strictly prohibited.

(1) Structural Rerouting: The Contractor must physically reroute or modify the existing overhead wet pipe mains and branch lines so that no water-filled piping or sprinkler heads are positioned directly over the footprint of the gantry mill or its associated swarf collection areas.

(2) Sloped Ceiling Compliance (4:12 Pitch):

(a) The FPE shall design the layout to comply with NFPA 13 rules for

Sloped, Unobstructed Ceilings.

(b) Standard ESFR sprinklers are strictly prohibited on slopes exceeding

2:12 and must be replaced with Code-compliant CMSA or Standard Spray sprinklers.

(3) Deflector Orientation & Elevation:

(a) All overhead sprinkler drops must utilize specialized hardware to ensure the sprinkler deflectors are installed perfectly parallel to the 4:12 slope of the new fabric ceiling.

(b) Sprinklers shall not be flush-mounted; deflectors must sit securely below the new fabric ceiling within the strict distance tolerances required by NFPA 13.

(4) Thermal Envelope Coordination:

(a) The Fire Suppression Contractor shall coordinate with the Insulation

Contractor to ensure the fabric liner is penetrated safely and precisely around the new pipe drops.

(b) The Insulation Contractor shall 100% vapor-seal the fabric liner directly to the rigid pipe drop or flexible hose utilizing approved vapor barrier tape/mastic.

(c) No adhesives, tape, or fabric shall come into contact with the sprinkler head, escutcheon plate, or thermal bulb. Escutcheon plates shall be installed after the vapor seal is confirmed.

SOW for PR 012-26 Page 10 of 23

c) Localized Mill Suppression (Sequenced Floor Installation) - To protect the facility structure while preventing catastrophic water-to-aluminum reactions, the FPE shall design a highly coordinated strategy. Note: Due to the operational envelope of an active overhead bridge crane, the construction of a physical "water exclusion canopy" or fixed deflector shield above the gantry mill is strictly prohibited.

(1) System Type: The FPE shall design and specify a dedicated, localized

Clean Agent or specialized Class D system utilizing a residue-free or equipment-safe agent.

(2) Mounting & Structural Validation: Heavy agent cylinders shall be anchored to the concrete floor. The lightweight delivery piping grid suspended from the building structure must be designed to avoid the bridge crane and be validated by a stamped structural analysis to prove it does not overstress the PEMB frame. The design must include any necessary reinforcements.

(3) Sequenced Floor Mounting & Rigging Coordination: The localized suppression hardware (tanks, piping pedestals, and detection sensors) shall be designed to be anchored directly to the concrete floor.

(a) Phasing Constraint: To prevent interference with the heavy rigging and installation of the gantry mill, the Fire Suppression Contractor shall NOT install or anchor any floor-mounted suppression components until after the gantry mill has been fully rigged, placed onto its foundation, and structurally secured by the Mill Contractor.

(b) Pre-Installation Coordination: Prior to drilling or anchoring, the Fire Suppression Contractor must conduct a joint site-walk with the Mill Installation Contractor and the COR to finalize the exact placement of the floor pedestals. The placement must ensure optimal nozzle coverage for fire suppression while maintaining the required operational clearances for the mill's moving gantry, operator access paths, and routine maintenance panels.

(4) Shunt-Trip Integration: This localized system must be integrated with the facility's fire alarm panel to trigger an immediate "shunt-trip," automatically de-energizing the gantry mill and its exhaust system upon detection of a fire.

The contractor shall clean up the material spilled and dispose of said clean up material at the Contractor’s expense.)

OSHA Spill Requirements – OSHA Act, Section 5(a)(1) OSHA regulations require employers to have spill containment provisions in areas where spills may occur, including appropriate personal protective equipment (PPE) and cleanup materials. Spill kits should contain items like absorbent materials and socks, disposal bags, and PPE such as gloves and safety glasses. The specific requirements depend on the nature of the potential spill, such as oil, or chemicals, such as fuel or antifreeze. This is enforced under the General Duty Clause (Section 5(a)(1) of the Occupational Safety and Health Act).

EPA Spill Requirements – 40 CFR, Part 112 The EPA regulates spill kits primarily through its Spill Prevention, Control, and Countermeasure (SPCC) rule, which focuses on preventing oil spills from reaching navigable waters. This rule, and related regulations, requires facilities to have secondary containment systems and accessible spill kits for quick response. A basic spill kit typically includes absorbent materials (pads, socks, booms, etc.), personal protective equipment (gloves, goggles), disposal bags, and a container for easy portability. The purpose is to contain spills and prevent them from reaching soil, groundwater, or surface water.
