Types “E”, “G” and “F” pallet rack shall be located in Area B as designated on the building 2163 key plan shown on AF Drawings BFR1B0-01 and BFR1B0-02. The racks shall be capable of being assembled sidebyside, in a row, using common uprights to support the shelf beams.

Upright frames The upright frames shall be of steel, all welded construction consisting of two columns, diagonal and horizontal braces, and floor bearing plates. Each upright frame shall be capable of supporting fully loaded bays without permanent deformation. The upright frames of like racks shall be interchangeable. Upright frames shall meet the requirements listed in the table below, as a minimum.

Safety factor: 1.92 to 1

Columns The columns shall be a continuous channel, box channel, rectangular, square or other formation approved by the Contracting Officer or Technical Representative (COTR). Each column shall have openings to readily accommodate beam connectors, end-to-end, at corresponding heights through the height range of the column openings. The openings at the bottom shall allow for the tops of shelf beams to be installed at six inches above the ground and shall continue upward to the top of the column by 2 inch increments. All openings of each column shall be identical to each other and identical to the openings of all other columns. The position of all corresponding openings of the columns shall not vary more than 3/32 inch as measured from the bottom of the bearing plates. The arrangement of the openings and the fastening devices of the beams shall be such that the tops of the beams are flush, within 3/8 inch, with the top of the column. The width of the column, facing the aisle, shall be a minimum 2 7/8 inches.

Bearing plates The bottom of each column shall have a load bearing plate securely attached. Each bearing plate shall be sufficiently sized to disperse the maximum load imposed by the column. Each bearing plate shall have a minimum of two punched holes to accept minimum 1/2-inch anchor bolts in accordance with 3.2.6.

Diagonal/horizontal bracing The columns shall be braced by horizontal and diagonal braces. Each end of all braces shall be securely welded to the columns. The braces shall not protrude beyond the sides of the columns or obstruct the attachment of the shelf beams to the columns, at any height on the columns. The centerline of the bottom horizontal brace shall not be located more than 12 inches from the bottom of the upright frame, and the centerline of the top horizontal brace shall be located not farther than 12 inches from the top of the upright frame. Other diagonal and horizontal braces shall be uniformly spaced between the top and bottom horizontal braces.

Shelf beams Shelf beams shall be the box or step type. Any openings in the shelf beam construction shall face inward, they shall not face the aisle. The connector shall not be welded to the column. Shelf beamtocolumn connection shall be of the locking type. Each pair of shelf beams shall provide a bay width of 108 inches for Types “E” and “G”; 96 inches for Type “F”, with a uniformly distributed load of 6,000 pounds per bay, there shall be no permanent deformations, and elastic deflections shall not exceed 0.56 percent of the unsupported span, measured with respect to the two ends of the beam. Shelf beams shall be designed with a safety factor of 1.65 to 1. If cross-ties are used they shall be the drop-in type, the use of mechanical fasteners or welding is unacceptable.

Connectors Each end of the shelf beams shall have a multiple prong slipfit or slipjoint type shelf beamtocolumn connector. Separate shelf beams and connectors are unacceptable. The connectors shall be adjustable, allowing the shelf beams to be moved with no more than the use of a soft hammer. The connector shall be capable of transferring all loads and external forces of the shelf beam to the column without failure of the connection, or damage to the column or connector. The prongs shall be of sufficient number, size, and strength to withstand repeated loading and unloading of the rack, and to continually sustain the rated shelf beam load. The prongs shall engage with the openings of the columns in such a manner to prevent lateral rotation of the beam, with each prong contributing to the support of the beam. The prongs shall engage with the openings of the columns to ensure a snug metaltometal fit between the horizontal and vertical load carrying members. The prongs shall be of the same design as the opening.

Shelf beamtocolumn safety lock Each shelf beamtocolumn connection shall have a safety lock which shall lock the shelf beam to the column. The design and manner of construction of the device shall prevent accidental disengagement of the shelf beamtocolumn connection during movement or shifting of the assembled rack unit due to impact to the upright frame or shelf beam from horizontal or vertical directions. The safety locking device shall be an integral, attached part of the shelf beam. The safety lock shall be employed without the use of tools, and no part thereof shall obstruct or restrict the loading or unloading of the racks.

Leveling shims Leveling shims shall be provided with the rack units where necessary. The shims shall have holes corresponding to the holes in the bearing plate, and shall anchor or lock with the bearing plate when the rack is erected. Shims shall be equal in width and length to the bearing plate under which it is installed. Shims shall be of varying thickness so no more than five shims are installed at any point. Slotted shims shall be unacceptable.

Anchoring the structure The rack system shall be anchored to resist all design shear and uplift forces. The rack units shall be designed to be a rigid freestanding structure and shall not be connected to any existing building structure except the floor. Each bearing plate shall be securely anchored to the floor with minimum one 1/2-inch diameter anchor bolt. The minimum embedment of the anchor shall be in accordance with 3.3.2.3 of the Cover PD.

Assembly The assembled pallet rack system shall be rigid, stable, and without deformation or skewing when each bay is loaded to the capacity of the design loads. The pallet rack system shall assemble so that the columns are perpendicular to the beams and parallel to each other. Shelf frames shall be straight and square. All horizontal members shall be level to within 1/8 inch per 10 feet measured over any distance in the rack system.

Pallet supports A minimum of four steel pallet supports per bay shall be installed. The top of each pallet support shall be flush with the tops of the front and back shelf beams to within 1/8 inch. Each pallet support shall be capable of supporting a minimum safe load of 1,500 pounds. All pallet supports shall be flanged at the front and back of the support to inhibit accidental dislodging of pallet supports. Pallet supports shall be designed with a safety factor of 1.65 to 1.

wire Decking Wire mesh decking shall be installed in all bays between all parallel shelf beams and uprights. The decking shall be heavy duty welded steel wire with integral support channels capable of supporting a uniformly distributed load of 6,000 pounds per bay. The decking shall be designed with a safety factor of 1.65 to 1. The decking shall not exhibit permanent deformation and elastic deformations shall not exceed 0.56 percent of the unsupported span. The decking shall be plated or galvanized to protect against corrosion. Decking shall be the appropriate type to interface with the type shelf beam being provided. The ends of the wire mesh decking shall bend over the shelf beam to provide a secure load supporting deck and keep the decking from accidentally disengaging from the shelf beams. Where building columns are located within the pallet racks and where decking is required, the Contractor shall provide a useful decking bay by cutting the decking to fit around the building column.

QUALITY ASSURANCE PROVISIONS

Inspection 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.

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

3.1. and 3.2.3.

Three pallet bays, picked at random, shall each be loaded with two 3,000-pound pallets (total 6,000 pounds) to ensure the pallet beams are set in place. The loads shall then be removed. The distance from the top of each designated shelf beam to the top of the shelf beam above it shall be measured and recorded as M1. The 3,000-pound pallets shall then be put back into the designated pallet bays. The loads shall be left for a minimum of four continuous hours. The distance from the designated shelf beams to the top of the next shelf beam shall be measured again and recorded as M2. The following formula shall be used to determine the deflection amount:

Types “E” and “G” Deflection = [(M1 - M2) / 108] * 100 Type “F” Deflection = [(M1 - M2) / 96] * 100 If the deflection is greater than 0.56 or if permanent deformation exists when the loads are removed, the system shall fail.

Types “E” and “G” Deflection = [(M1 - M2) / 108] * 100

Type “F” Deflection = [(M1 - M2) / 108] * 100

If the deflection is greater than 0.56 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.
