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 shelving area will be performed manually, using stock-picking ladders. The shelving system shall be located so personnel can operate safely in the aisles without damage to shelving units, property stored, or injury to personnel. 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 Drawing ATY0B9-01. These shelving units shall be arranged in rows by attaching them together end-to-end and/or back-to-back.

Shelving unit design 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 shall be 36 inches wide and 24 inches deep.

Shelf capacity Each 36-inch wide by 24-inch deep 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 size The supporting posts shall be 123 inches high.

Supporting post capacity Each front and back supporting post shall have a minimum capacity of 1,400 pounds based on 19 inch shelf spacing without any visible evidence of permanent deformations.

Supporting posts design Mounting holes for clips shall be provided on the supporting posts. Mounting holes shall 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 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 for any shelving unit under 147 inches high. Supporting post splices shall not interfere with the specified shelf placement.

Assembled dimensions The following tolerances shall apply to the assembled dimensions of the shelving units:

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 from the stationary platform and mobile carriages to the top of the unit. Overlapping of two or more back panels will be acceptable in lieu of one continuous panel from top to bottom for backs over 87 inches high. Back-to-back shelving units shall share a single, common back panel between each unit. The back panels shall be secured to the supporting posts. Shelves shall not be used to secure the back panels into position. Screws used to secure the back panel shall not prohibit the installation of shelves. Back panels of a single row of shelving, not against a wall, shall include extra screws or equivalent to prevent gaps and ripples vertically and horizontally between other back panels and/or the supporting posts.

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 fully enclose the ends of a shelving unit and shall extend from the top of the shelving unit to the stationary platform and mobile carriages. Overlapping of two or more side panels will be acceptable in lieu of one continuous panel from top to bottom for ends over 87 inches high. Side-by-side shelving units shall share a single common side panel between each unit.

Base strip A steel strip shall be provided and installed on each shelving unit between the bottom shelf and the stationary platform and mobile carriages.

Foot plates Each supporting post shall have a foot plate attached and shall be secured to the fixed platforms and mobile carriages with anchor bolts. The foot plates shall distribute the weight of a fully loaded shelving unit over the fixed platforms and mobile carriages. Foot plates shall be positioned to not interfere with erection of adjoining units and still provide ease of access for anchoring procedure. Foot plates shall be concealed behind the base strips.

Freestanding structure The shelving system shall be designed to be a rigid freestanding structure and shall not be connected to any existing building structure except the stationary platform and mobile carriages. The shelving units shall be designed to resist all shear and uplift forces.

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 After assembly, the shelving units shall be capable of maintaining the same position in a loaded, partially loaded, or empty capacity. 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 stationary platform and mobile carriages 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 approval by the COTR as a part of the shop drawing submittal.

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) / 36] * 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.
