STATEMENT OF OBJECTIVES

ACTIVRAC STORAGE SOLUTION

I. INTRODUCTION: The 736th Security Forces Squadron (SFS) seeks a High Density Mobile Storage solution that will maximize space utilization for the 736 SFS supply room warehouse, which has limited available space.

II. SCOPE: The 736 SFS requires mobile pallet racks with customized, modular and component-based storage solutions in order to provide more efficient storage for the mission. The system will enhance transferability of stored assets to deploy in a manner that maximizes utilization of finite space, enhances overall utility, and conforms to physical security and safety standards. The solution shall enhance equipment readiness, increase asset accountability, maximize space utilization, aid/assist in issue/recovery, and solve problems associated with current deficiencies in properly storing items required for the 736 SFS’s mission.

III. SYSTEM REQUIREMENTS

General: The system consists of storage units mounted on manufacturer’s track-guided carriages to form a compact storage system. System design permits access to any single aisle by manually moving units until the desired aisle is opened. The carriage/rail system provides uniform carriage movement along the total length of travel, even with unbalanced loads.

Carriage System Design and Features: The carriage system consists of a formed structural steel frame with machined and balanced wheels riding on unleveled steel rails [recessed] [surface] mounted to the floor. Rails shall be type selected by the manufacturer to ensure smooth operation and self-centering of mobile storage units during travel without end play or binding. Rail types, quantities and spacing shall be selected by the manufacturer to suit installation conditions and requirements. All bearings used in the drive mechanism shall be permanently shielded and lubricated.

Movement Controls: Triple arm operating wheels with rotating hand knobs shall be provided on the accessible (drive) ends of shelf units, centered on the stanchion, located approximately 40 inches (1051MM) from the base of each unit to permit units to be moved to create a single aisle opening. Turning the handle transmits power through chain drive to drive wheels on each carriage.

Drive System: The system shall be designed with a positive type mechanically-assisted drive, which minimizes end play, ensures there is no play in the drive handle, and that carriages will stop without drifting.

System shall include a chain sprocket drive system for each movable carriage to ensure that carriages move uniformly along the total length of travel, even with unbalanced loads. All system components shall be selected to ensure a smooth, even movement along the entire carriage length. Drive system gearing shall be designed to permit 1 lb. of force applied to the drive handle to move a minimum of 4,000 lbs. of load.

A tensioning device shall be provided on each chain drive with provision for adjusting tension without removing stanchion covers.

All bearings used in the drive mechanism shall be permanently shielded and lubricated.

Safety Features:

Color-coded visual indicators shall provide verification that carriages are in a locked or unlocked mode.

A single safety lock button, mounted on each operating wheel hub, will permit moving a carriage in either direction to create a new access aisle when pulled out (unlocked), or locking the carriage when pushed in.

Finishes:

Fabricated Metal Components and Assemblies: Manufacturer’s standard powder coat paint finish.

The information provided in Attachment l is for guidance purposes to help depict the direction of the requiring activities vision. Alternate proposed storage solutions will be accepted and evaluated if within the scope of this contract.

IV. 2.3 MANUFACTURED COMPONENTS

A. Rails:

1. TOP MOUNT: Rail shall be ASTM/AISI 4140 steel bar 4 1/2” (114mm) wide x 3/8” (9.5mm) high. Rail edges shall be beveled down to a maximum of 3/16” (4.8mm) to allow for the rail to be transverse by material handling equipment. Rail shall disperse the wheel point loads to structural slab. Rail shall have two permanently mounted floor anchors maximum 15” (381mm) on center. Rails shall be installed on top of concrete slab and laid in a manor such that rail joints are staggered across all adjacent rail runs. Rail and carriage design allows concrete slab to be unleveled at the following maximum variation of 3/16” (4.8mm) over any 2’ (0.6m) rail run and 1/4” (6.4mm) maximum variation over any 10’ (3.04m) rail run.

B. Carriages:

1. Assembled structural steel carriage base will have a minimum capacity of 7,000 lbs. (3,175 kg) Each wheel assembly shall be equipped with two wheels, minimum 5” (127mm) diameter steel wheels. Wheels are equipped with two permanently lubricated and shielded radial ball bearings. Wheel capacity 3,500 lbs (1,587kg) each. Wheels have solid steel axles of 1” in (25.4mm) diameter. Wheels shall be dual flange, all wheel guided. All carriage sections between wheel assemblies have integral cross bracing to maintain accepted tolerances for function of systems. Side profiles shall provide and maintain wheel assembly alignment and squareness. These profiles shall be pre-drilled at the factory but are bolted and assembled on the job site as integral carriage members.

2. Structural steel side profiles shall be minimum 5.084” (129mm) high, 10 gauge (2.5mm).

3. Finish shall be powder coat paint.

4. Provide manufacturer's design movable carriages fabricated or bolted steel construction. Galvanized structural components and/or riveted carriages are unacceptable.

C. Drive / Guide System:

1. Design: Provide drive system which prevents carriage whipping, binding and excessive wheel/rail wear under normal operation.

2. Shafts: Solid steel tube.

3. Shaft Connections: Secured couplings.

4. Bearing Surfaces: Provide rotating load bearing members with ball or roller bearings. Provide shafts with pillow block or flanged self-aligning type bearings.

V. PERFORMANCE REQUIREMENTS

A. Ease of Movement: Provide mechanically assisted units capable of being moved by exerting a maximum horizontal force of 5 -10 pounds on the operating wheel.

B. Seismic Performance: Provide mobile storage units capable of withstanding the effects of earthquake movement when required by applicable building codes.

VI. 2.1 MANUFACTURERS REQUIREMENTS

A. General: Products are based upon mobile shelving system products manufactured by Spacesaver Corporation. Contingent on meeting specification requirements, other acceptable manufacturers may be included.

VII. PLACE OF PERFORMACE

1. The primary place(s) of performance is as follows:

736 SFS

Andersen Air Force Base Guam Bldg 23022

APO, AP 96543

a. The primary place of performance refers to the location of 736 SFS Supply Warehouse North West Field, which will be the designated location for design site visits, delivery, installation, and any required follow-on support.
