SCOPE

General scope This appendix establishes the minimum performance, design, fabrication, installation, and test requirements for a bin shelving system for the Wyoming ANG at Cheyenne. The work shall be completed in accordance with this appendix, the Cover Purchase Description (PD), and Air Force (AF) Figures 1-8. This appendix covers all equipment, materials, and labor necessary to complete installation of the system.

Definitions Back panel - Sheet steel panels attached to the two rear posts of each unit to enclose the back of the unit or form a partition between units placed back to back.

Foot plate - Formed steel plate attached to supporting posts used to anchor the shelving units to the carriages or stationary platform.

Shelf - Formed sheet steel which attaches horizontally to supporting posts and supports a load.

Shelf clip - A formed steel piece that provides for attachment of shelves and posts without the use of nuts and bolts.

Shelving unit - A single structure comprising of supporting posts, shelves, and side and back panels.

Side panel - A sheet steel panel attached to the front and rear post to enclose the side of each unit, or as a partition between units placed side by side.

Supporting post - Steel vertical upright member that supports horizontal shelves.

APPLICABLE DOCUMENTS

Applicable documents shall be in accordance with Section 2 of the Cover PD.

REQUIREMENTS

System description Storage and/or retrieval operations within the mobile storage system will be performed using a rolling ladder stand. The shelving system shall consist of:

A. Shelving units B. Nuts, bolts, anchors and any other items required to install the shelving system

Physical and Performance Characteristics Shelving layout The shelving system shall consist of shelving units in accordance with AF Figures 1-8. These shelving units shall be arranged in rows by attaching them together end-to-end and/or back-to-back.

Shelving unit design Solid steel shelving shall be secured to the supporting posts by means of positive engaging clips. All shelving, including parts and assemblies, shall be identical.

Safety factor Design and construction of each load bearing component shall assure that the component is capable of sustaining the specified load with a minimum safety factor of 1.65 to 1.

Shelf details Shelf size The shelves sizes shall be as shown on Air Force Figures 3-8.

Shelf capacity Each shelf shall be capable of sustaining a uniformly distributed static load of 400 pounds with an elastic deformation less than 0.875 percent of the unsupported span length, measured with respect to the two ends of the shelf and without any permanent deformation.

Shelf design Plain shelf edges shall be flanged down on all sides not less than 1-1/8 inch nor more than 1-1/2 inches, with not less than one additional return flange on each side.

Shelf clips Shelf clips shall be provided in sufficient quantity to secure each of the four corners of each shelf to all four supporting posts. The shelf clips shall be designed to preclude the possibility of accidental disengagement of the clips from the post or the shelves under loaded conditions. The shelf clips shall allow for the spacing of the shelf to be changed with minimum disturbance to surrounding shelves and shelving units. Shelf clips shall be capable of being changed with no more than a hammer.

Supporting posts Supporting post design Supporting posts shall be 10 feet high. Mounting holes for clips shall be provided on the supporting posts, which permit adjustment of shelf height on either 1-inch or 1 1/2-inch increments. Holes shall be provided as required for attachment of all back and end panels. Supporting posts shall be provided at all four corners of all shelving units. Common supporting posts may be used at adjacent corners of single or double faced racks.

Supporting post type The front supporting posts shall be either beaded or box type as defined by the Shelving Manufacturers Association. Supporting posts shall be continuous (no splices).

Back panels Back panels shall have either predrilled or punched mounting holes which match up to mating holes in the supporting posts. Back panels shall be made of metal and shall fully enclose the back of the shelving unit. Back-to-back shelving units shall share a single, common back panel. Back panels shall be secured to the supporting posts. Shelves shall not be used to secure the back panels into position.

Side panels Side panels shall have either predrilled or punched mounting holes to match up to mating holes in the supporting posts or shall be factory welded to supporting posts. Side panels shall be made of steel and shall fully enclose the ends of a shelving unit. Side-by-side shelving units shall share a single common side panel.

Foot plates Each supporting post shall have a foot plate attached and shall be secured to the stationary platform or carriage. Foot plates shall be positioned to not interfere with erection of adjoining units and still provide ease of access for anchoring procedure.

Freestanding structure The shelving system shall be designed to be a rigid freestanding structure and shall not be connected to any structure except the stationary platform or carriage.

Assembly The Contractor shall assemble, on site, all shelving units including bracing, panels (side and back), and shelves as specified in this appendix in the quantities necessary to meet the storage requirements specified.

Alignment Alignment of each row of shelving units shall be in all three directions, down each row of shelving units, from row to row, and vertically for each shelving unit face.

Aisle alignment Shelving unit face alignment shall be maintained down each row within 1/8 inch from one shelving unit to the next.

Shelving unit vertical alignment Each shelving unit face shall be plumb to within 1/4 inch from the bottom to the top of the unit. Each supporting post shall be plumb to within 1/4 inch when examined from any direction. All shims used shall be secured beneath the foot plate. The shims shall be the same size as the foot plate and shall have a hole(s) to correspond with the hole(s) in the foot plate for anchoring.

Color The contractor shall submit a color chart for selection by the User at the Post Award Orientation Conference.

QUALITY ASSURANCE PROVISIONS

Inspections The system shall be inspected to verify that it meets all the requirements of sections 1, 2, and 3 of this appendix and the Cover PD. These inspections shall be completed as part of the system checkout test and again as a part of the quality conformance test.

Test The following test shall be performed on the system as part of the system checkout test and again as a part of the quality conformance test.

Deflection = [(M1 - M2) / shelf width] * 100 If the deflection is greater than 0.875 or if permanent deformation exists when the loads are removed, the system shall fail.

Certifications The Contractor shall provide certification that the following requirements have been met. All certifications shall be provided in accordance with the Contract Data Requirements List.
