PROJECT TITLE: Building 153 Secure Caging, High-Density Mobile Storage, and Architectural Finishes Modernization

FACILITY LOCATION: Building 153 (WRNMMC Logistics / Warehouse Facility) Scope of Work Key requirements include:

Mechanical surface preparation (sanding/diamond grinding) and installation of a commercial-grade, high-gloss "showroom shine" non-slip epoxy/polyaspartic floor coating system.

Two-tone architectural wall coating (half-wall dark gray lower wainscot and off-white upper wall).

Procurement, assembly, and anchoring of six to eight (6–8) modular heavy-duty wire partition storage cages equipped with digital keypad access control locks.

Procurement and installation of a rail-less, overhead-suspended mobile high-density shelving system.

Electrical tie-ins and integrated overhead LED lighting inside all secure cage enclosures.

Operational Context Building 153 supports logistics, turn-in operations, and specialized medical/readiness materiel staging (including Medical Equipment, Medical Sets/Kits, CBRNE gear, and Non-Class VIII inventory) for the Walter Reed National Military Medical Center (WRNMMC) operational footprint. Modernizing the space is essential to maximize vertical storage density, enhance physical security, prevent slip-and-fall hazards, and provide a clean, professional, high-durability operational environment.

SPECIFIC REQUIREMENTS AND TASKS

Task 1: Concrete Floor Mechanical Preparation & Non-Slip Showroom Coating Apply a multi-coat, industrial-grade resinous floor system designed to withstand heavy foot and material-handling traffic while maintaining a mirror-reflective, high-gloss "showroom shine" coupled with an OSHA-compliant non-slip safety profile.

Surface Assessment & Moisture Mitigation:

Conduct ASTM F1869 (calcium chloride) or ASTM F2170 (in-situ relative humidity) testing to verify concrete moisture levels before application.

Remediate oil, grease, old sealers, chemical residues, and contaminants.

Mechanical Surface Profiling (Sanding & Grinding):

Mechanically grind/sand the designated concrete slab area using planetary diamond grinders and edge sanders equipped with HEPA-filtered vacuum containment systems.

Achieve an International Concrete Repair Institute (ICRI) Concrete Surface Profile (CSP) of #2 to #3.

V-groove, clean, and fill all dynamic control joints, cracks, divots, and spalls using an approved structural polyurea/epoxy joint elastomeric filler flush with the adjacent slab.

Primer & Base Coats:

Apply a high-penetration 100% solids epoxy moisture-blocking primer coat.

Apply a high-solids pigmented epoxy body coat (color selected by Government; neutral/light aircraft gray recommended) to achieve a uniform, opaque, level substrate.

Non-Slip Additive & Showroom Topcoat:

Incorporate fine micronized spherical polymer or aluminum oxide non-slip aggregate evenly broadcast or suspended into the intermediate/topcoat to provide dynamic slip resistance (minimum Wet Dynamic Coefficient of Friction [DCOF] per ANSI A326.3).

Apply a UV-stable, chemical-resistant high-gloss polyaspartic or urethane topcoat that provides exceptional clarity, abrasion resistance, and a reflective "showroom shine" without diminishing slip resistance.

Install/replace vinyl or rubber cove base along perimeters where applicable.

Task 2: Architectural Wall Preparation & Painting Prepare and repaint the interior perimeter warehouse wall running along the build-out span (~80 linear feet):

Surface Preparation:

Clean to remove dust, scuffs, grease, and drywall imperfections. Patch nail holes, dents, and surface abrasions with drywall compound; sand smooth.

Two-Tone Scheme Execution:

Lower Section (Half-Wall Wainscot): Apply two (2) coats of premium commercial semi-gloss acrylic enamel paint in Dark Gray up to 48–54 inches from finished floor level (exact datum line coordinated with Contracting Officer Representative [COR]).

Upper Section: Apply two (2) coats of premium commercial satin/semi-gloss acrylic enamel in Off-White/Neutral from the wainscot line up to the ceiling transition/deck.

Establish a crisp, laser-straight transition line dividing the dark gray and off-white coats.

Task 3: Secure Modular Wire Partition Caging The Contractor shall engineer, supply, and assemble modular, floor-anchored wire partition enclosures dividing the ~80 ft. wall length into six to eight (6–8) discrete, secure cage compartments matching the layout plan (e.g., Bulk Storage, Loose Storage, Kit Storage, Medical Equipment, Non-Class VIII, CBRNE, and Desk workspace separation).

Wire Partition Specifications:

Panels: Minimum 10-gauge steel wire woven or welded in a or square mesh pattern, framed in structural steel angle frames.

Posts/Mullions: Minimum 2" square tube posts with welded baseplates securely anchored into the concrete floor using heavy-duty wedge anchors.

Height: Minimum 8 to 10 feet nominal height (or full floor-to-joist enclosure as coordinated with facility fire clearance).

Finish: Factory powder-coated finish (Industrial Gray, Platinum, or Black).

Doors & Access Control:

Provide one (1) sliding or heavy-duty swing door per partitioned cage bay (minimum 36" clear opening width for equipment carts).

Equip each cage door with a self-contained, battery-powered or hardwired commercial digital keypad electronic lock (e.g., Trilogy, Simplex, or equivalent enterprise keypad latch).

Locks must support multi-user PIN assignment, mechanical key override, and audit capabilities.

Task 4: Rail-Less High-Density Mobile Storage System To maximize storage capacity without drilling tracks into the freshly coated showroom floor, install an overhead-suspended, rail-less mobile shelving system (e.g., Spacesaver Levpro Series 8/10/12 or equivalent).

System Architecture:

Overhead track and trolley design suspended from heavy-duty structural steel pallet rack uprights or self-supporting bridge beams.

Zero floor tracks: the finished showroom floor must remain completely unobstructed and smooth underfoot for cart movement and cleaning.

Dimensions & Capacities:

Shelf widths: 18" to 24" deep shelves configured within 8-ft, 10-ft, or 12-ft system modules.

Total system weight capacity: Minimum 4,200 lbs to 4,800 lbs per bay section; individual shelf load ratings must exceed 150–600 lbs per level.

Wire mesh decking or solid steel shelves with ergonomic handles on movable sections for smooth lateral gliding.

Safety & Stability:

Overhead trolley anti-tip and mechanical stop mechanisms to prevent derailment.

Footings shimmed, plumbed, and securely bolted to avoid vibration or racking.

Task 5: Cage-Dedicated LED Illumination Integrate dedicated interior lighting for all 6–8 caging bays:

Fixtures:

Industrial LED strip or linear high-bay fixtures (minimum 4000K–5000K daylight, CRI , minimum 50 foot-candles at shelf working surfaces).

Fixtures shall be UL-listed, energy-efficient, and encased in impact-resistant polycarbonate or acrylic diffusers.

Electrical Integration:

Run wiring in rigid metal conduit (EMT) secured along wire partition frames in compliance with NFPA 70.

Provide independent local wall/toggle switches or PIR occupancy motion sensors within each cage to maximize energy efficiency.

Terminate circuits in the designated Building 153 distribution panel, verified and labeled by a licensed journeyman electrician.

Total duration shall be 45 calendar days from Notice to Proceed (NTP).

Standard Work Hours: Monday through Friday, 0700 to 1600 hours, excluding Federal holidays, unless after-hours work is requested in advance
