Typical Building Specifications

(Modular Prefabricated Hazardous Material Storage Building)

GENERAL BUILDING, CONSTRUCTION, AND PERFORMANCE

Standard Features Modular Hazardous Materials Storage Buildings are utilized when an owner/end-user requests a larger square-footage unit to be placed in a small footprint site area, where multiple stand alone buildings are not a reasonable alternative. Two or more units are shipped to the site area and erected by means of a rigging process and bolted together, for a complete installation. Modular construction may be utilized for any of our outdoor units. The portfolio includes Turfloc, Fireloc (Uni-directional and Bi-directional two hour fire rating), Superloc (Bi-directional four hour fire rating), Drumloc, Chemloc and Magloc (for both ATF and Military standards). Explosion and non-explosion proof construction is offered as directed by codes/regulations or owner requests. Due to transportation constraints, units are not to exceed 14’- 0" in width and 62’- 00" in length.

Each modular quotation is catered to the customers needs and the series construction as mentioned above. Particular attention is addressed to the accessories package as listed below. Where units have specific fire ratings or explosion proof designs, the factory installs these accessories to exacting specification and code requirements. This value-added service insures the owner/end-user that their unit is compliant and saves any outsourcing after the factory installation of the modular units has been installed.

The specification listed below is for the modular Chemloc series, with non-combustible and a non-fire rated construction. Please consult with the factory for specific specification requirements.

General Arrangement and Submittal Drawings are furnished with an engineer’s seal prior to submittal to the owner/end-user, architect or engineer. Third party and State Approvals are available in all 50 states and territories.
The Steel used to fabricate the model quoted here is the highest-grade American made steel and is free from rough edges, kinks, and sharp bends. Our manufacturing does not reduce the strength of the steel to a value less than intended by the UL design. Our manufacturing is done in a neat and precise fashion, while all bends are made by controlled means to ensure uniformity and strength. Our welding procedures are in accordance with the American Welding Society and meet standards set forth by the ASTM, and all welds are sufficient in size and shape to accommodate UL listed wall designs.

The Modular Prefabricated Locker has non-combustible weatherproof construction with welded exterior 12-gauge steel panels and 10-gauge sump for maximum durability and strength. Wall studs are 3-1/2" by 2" for superior strength, manufactured from 12-gauge steel and producing a 3-1/2" wall cavity ready to accept standard insulation if required. Continuously welded roof and sump sections provide added rigidity in transit and use.
The Roof and Ceiling have the same non-combustible weatherproof construction as building walls. It is continuously welded 12-gauge steel roof permanently attached to building and comes equipped with a rain shield over door. At the roof apex, on each unit, is C8x11.5 structural channel, with ¼"steel gussets is welded full length on the unit. The two adjoining units are pulled together at the roofline, with 5/8" A307 structural bolts 24" on center and double bolted at the ends.

The Secondary Spill Containment Sump is built in 7" deep leak-tight secondary containment sump, which surpasses FM spill containment requirements. Sumps start at 7" deep and may be increased in one-inch incremental depths to meet additional EPA requirements or other regulations. Heavy-duty construction utilizes 10-gauge steel for superior structural support. Removable galvanized steel floor grating rated 500psf for heavy drum/pallet loads. Structural steel floor supports are easily removed for clean up of spills within the sump. Each individual unit contains it’s own sump unless otherwise specified. Adjoining sumps are stitch welded together and covered with a hat channel.

The Building Base has open channel construction for under-sump inspection. The steel C-channels and hold down brackets are provided for ease of offloading and securing to site. The building base also attains seismic and wind load anchoring. Incorporated into the base is a series of steel tubes 4"x3’’x1/4" and 3"x2"x1/4" used to align and draw the separate buildings together, which in turn are bolted together at the endwalls.

The Static Grounding System has three (3) Interior grounding lugs, one (1) exterior static grounding connection and one (1) galvanized steel grounding rod for prevention of explosive sparking hazards.

In the ventilation, there are Gravity Air Flow Vents in both high and low positions, with weatherproof galvanized steel frame and louvers to provide adequate air flow and natural draft.

Installation Units are delivered to the site via flat bed trailer and off-loaded by means of crane service and rigging. All accessories are located on the drawings for review and installed for owner acceptance, in factory conditions. This includes all necessary electrical wiring, plumbing and HVAC services for a complete installation. Final plumbing, electronic media or electrical service hook-up, on the building exterior, is owner furnished.

ADDITIONAL ACCESSORIES AND APPROVALS

Listed below are standard supplied and owner/end-user requested options.

The Signage is a permanent D.O.T. metal flip placard with rust proof aluminum holder and stainless steel clips. There is also one (1) pressure sensitive NFPA 704 Hazard Rating sign on door.
Certifications include Factory Mutual (FM) Approval and Warnock Hersey labels affixed.

The Building Finish: After an extensive cleaning process the interior and exterior surfaces are protected with a high performance 2-part epoxy base coat (primer) and a high finish polyurethane top coat providing proven interior chemical resistance as well as exterior abrasion, corrosion, UV resistance and exceptional durability.
