About this file
This specification covers cantilever racks to be installed at the Engineering Housing Maintenance Shop at Camp Santiago Joint Training Center in Salinas, Puerto Rico. The racks must be designed to withstand seismic loads and comply with ANSI MH16.3 standards. They are to include arms rated at 500 pounds each, 72-inch tall columns spaced at 3 feet 6 inches, and bases with anchorage for a single-side arm configuration. The steel components will be powder coated in a color selected by the Contracting Officer. Installers must be qualified and approved by the rack manufacturer. The contractor must provide engineered designs, product data, shop drawings, product schedules, and seismic certification for the racks.

CAMP SANTIAGO, PUERTO RICO AMENDMENT 01
1.6 QUALITY ASSURANCE
A. Installer Qualifications: An authorized representative who is trained and approved by manufacturer.
1.7 FIELD CONDITIONS
A. Environmental Limitations: Do not deliver or install cantilever rack until spaces are enclosed and weathertight, wet work in spaces is complete and dry, and temporary HVAC system is operating and maintaining ambient temperature and humidity conditions at levels intended for building occupants during the remainder of the construction period.
PART 2 - PRODUCTS
2.1 PERFORMANCE REQUIREMENTS
A. Delegated Design: Design cantilever rack, including comprehensive engineering analysis by a qualified professional engineer, using performance requirements and design criteria indicated.
B. Seismic Performance: Cantilever rack shall withstand the effects of earthquake motions determined according to ASCE/SEI 7.
1. Seismic Component Importance Factor: 1.5.
2.2 CANTILEVER RACK
A. Cantilever rack: Complying with ANSI MH16.3; field-assembled from factory-formed components; arms, columns, bases, and bracing, B. Manufacturers: Provide all components from a single manufacturer. Manufacturer must have supplied similar shelving systems for at least five years.
C. Arms: level, 42 inches long, 500 lb. capacity each, raised retainer at end.
D. Columns: 72" high, attachment for arms at 3 inch spacing, 3 per rack unit.
1. Column spacing: 3'-6".
E. Bases: to fit with columns and arms, with anchorage for single side arm configuration.
F. Steel Finish: Baked enamel or powder coat.
1. Color and Gloss: As selected by Contracting Officer from manufacturer's full range

CAMP SANTIAGO, PUERTO RICO AMENDMENT 01
2.3 ANCHORS
A. Floor Anchors: Galvanized-steel,post-installed expansion anchors. Provide number per unit recommended by manufacturer unless additional anchors are indicated in calculations.
2.4 FABRICATION
A. Fabricate cantilever rack components to provide field-assembled units that are square and rigid, with columns plumb and true and free of dents or distortion. Fabricate connections to form a rigid structure, free of buckling and warping.
B. Weld corners and seams continuously to develop strength, minimize distortion, and maintain the corrosion resistance of base metals. At exposed locations, finish welds and surfaces smooth and blended so surface is smooth after finishing and contour of welded surface matches that of adjacent surface. Weld before finishing components to greatest extent possible. Remove weld spatter and welding oxides from exposed surfaces before finishing.
PART 3 - EXECUTION
3.1 EXAMINATION
A. Examine areas, with Installer present, for compliance with requirements for installation tolerances and other conditions affecting performance of the Work.
B. Examine floors for suitable conditions where cantilever rack will be installed.
C. Examine walls to which cantilever rack will be attached for properly located blocking, grounds, or other solid backing for attachment of support fasteners.
D. Proceed with installation only after unsatisfactory conditions have been corrected.
3.2 INSTALLATION
A. Install cantilever rack level, plumb, square, rigid, true, and with shelves flat and free of dents or distortion. Make connections to form a rigid structure, free of buckling and warping.
1. Install braces, straps, plates, brackets, and other reinforcements as needed to support shelf loading and as required for stability.
2. Anchor cantilever racks to floor with floor anchors through floor plate. Shim floor plate to achieve level and plumb installation.
3.3 ERECTION TOLERANCES
A. Erect cantilever rack in accordance with industry standards.

3.4 ADJUSTING
A. Adjust cantilever rack so that arms and other components engage accurately and securely.
B. Provide labels per standards including arm capacities.
C. Replace cantilever rack components that have been damaged beyond successful repair by finish touchup or similar minor repair procedures.
3.5 MANUALS
A. Provide manuals for care and maintenance including instruction for adjusting arm heights.
