Price Supervisor’s Office Mobile Shelving project SECTION 105626 – CUSTOM SIZED HIGH-DENSITY MOBILE STORAGE UNITS (MECHANICALLY ASSISTED MOVEMENT)

1.0 DESCRIPTION OF WORK

Contractor shall supply and install custom mobile shelving unit in a designated room in the Manti La Sal Forest Service Office at 599 West Price River Drive in Price, Utah. The room has glued on carpet over a concrete floor. Contractor shall field verify dimensions and conditions of the room for the mobile shelving install prior to bid.

Contractor shall submit manufacturer’s specification and profile and elevation drawings of proposed mobile storage unit with cost proposal.

Each shelving units shall be 48”L x 15”W x 6’-10” H and will have 6 evenly spaced shelf levels. There shall be 8 shelving units per each mobile section. There shall be a total of 3 mobile sections. The total length of the system shall not exceed 195 inches. The system shall have safety features including an anti-tip rail and fully self-contained safety brake. The mobile shelving unit shall be installed such that the system can be anchored to the existing carpeted/concrete floor without the construction of a raised subfloor. See attached drawing for room layout with proposed mobile storage unit.

1.1 MEASUREMENT AND PAYMENT

2.0 PRODUCT DESCRIPTION

General: High density mobile storage system consisting of storage housings mounted on wheeled carriage assemblies riding on multiple steel rails. Purpose is to allow multiple ranges of storage housings to be accessed by means of on roving aisle, thus greatly reducing floor space requirements from that of conventional rows of storage housings.

A. Carriage: The carriage shall be formed of a welded structural steel frame with machined steel wheels mating and/or aligning to corresponding steel rails. All bearings shall be permanently lubricated and shielded. Rail shall have an anti-tip feature.

B. Drive Controls: Triple arm operating control with ergonomic user-friendly knobs shall be provided on the drive ends. A minimum of one operation knob per carriage shall be within ADA reach guidelines at all times.

C. Front Drive control consisting of chain, sprocket and upper drive bearing assembly shall be completely self-contained and enclosed within a steel housing independent of the face panel and shall be an integral part of the carriage structure. Carriage end panel drive assemblies which merely attach to the face panel and are not supported by a dedicated structure shall be unacceptable.

D. All bearings in drive system shall be permanently lubricated and shielded.

E. Safety Items: A user activated safety locking mechanism shall be provided at every carriage control to prevent unintentional carriage movement. Also a fully self-contained safety brake requiring no battery or external power source which activates a carriage brake by means of a side sweep panel on the carriage.

F. Finishes on Metal Components: All components shall be finished with an electrostatically applied Gloss-Tek powder coat, or equal. Finish shall consist of a non-glare raised surface that provides scuff and scratch resistance. Finish shall be a non-VOC emitting hybrid powder coat which meets or exceeds ASTM test criteria for adhesion, flexibility, hardness, and humidity resistance. A minimum of 29 standard manufacturer’s colors shall be submitted to the CO for review and selection.

G. Finishes on Laminate Panels: High pressure laminate finish shall be selected from the manufacturer’s standard high pressure Wison Art , or equal, available colors and patterns. Finish shall be submitted to the CO for review and selection.

3.0 SUBMITTALS

A. Product Data: Submit manufacturer’s product literature and installations instructions.

B. Drawings: Provide dimensional layout of complete system including elevations and room dimensions and details.

C. Samples: Provide 3 inch square sample of each color and texture selected.

D. Warranty: Submit a copy of manufacturer’s warranty E. Maintenance Data: Provide manufacturer’s operation manual, maintenance and care instructions, and instructions for care and cleaning of the finish.

4.0 INSTALLATION

A. Installer Qualifications: Provide an experienced installer who is authorized by the manufacturer to install a high density mobile system and has a minimum of 1 year experience doing so.

B. Installer shall deliver and install the mobile shelving unit at an approved date and time by the Contracting Officer. Installer shall clean up site upon completion of the project.

C. Field measurements and conditions: Verify all dimensions of perimeter area and proposed system at project site prior to manufacture of mobile shelving system. Ensure existing flooring is level and suitable for the mobile shelving system prior to bid.

5.0 MANUFACTURED COMPONENTS

A. RAIL:

Rail shall be ASTM/AISI Type 1045 steel and manufactured to carry a load of 1,000 pounds per lineal foot of carriage length Rail shall be designed to be anchored to a concrete floor Rail shall be positioned, leveled and grouted in accordance with the manufacturer’s instructions providing a minimum of 7/16 inch of grout under the rail from the high spot on the floor. Void under leveled rail shall be completely filled with a non-shrink grout.

Rail shall be positioned, leveled and grouted in accordance with the manufacturer’s instructions providing a minimum of 7/16 inch of grout under the rail from the high spot on the floor. Void under leveled rail shall be completely filled with a non-shrink grout.

Shimming of rail is not acceptable either as a means of support or for leveling. Rail shall be drilled and tapped to accommodate leveling screws adjacent to all anchor holes. Each rail must extend completely under all stationary ranges.

RAMP

Ramp shall be constructed of stainless steel or galvanized steel Ramp shall not extend beyond the end of the carriage if at all avoidable. The vertical transition from the ramp edge to the floor shall be a maximum of 1/8 inch with ramp having a maximum slope of 9 degrees.

Ramp shall extend under all mobile and stationary carriages

CARRIAGE

Carriages are to welded steel construction. Riveted or bolted carriages shall be unacceptable. Galvanized components are unacceptable. Components of unlike finish or material are unacceptable.

Carriage shall be designed for a capacity of 1,000 pounds per linear foot.

Carriage construction shall provide for shelving to be securely anchored with vibration-proof fasteners.

Carriages designed to recess the shelving or storage housing, thus causing the carriage to protrude beyond the plane of the face of the shelving or storage housing shall be unacceptable.

Carriages shall be powder coat finished inside and out. Galvanized components are unacceptable.

Carriages shall be straight and square. There shall be no movement in any splice or welded joint when loaded to recommendation and normal operation is applied.

WHEELS

All wheels whether load or driven shall be a minimum of 5 inches in diameter, constructed of cast ductile iron , and precision machined for smooth operation and to ensure compatibility to the corresponding rail.

Bearings shall be permanently lubricated and shielded.

Dynamic load rating on wheel bearings shall be a minimum of 4,400 pounds per wheel.

GUIDANCE

Guide design: a minimum of 2 guide rails shall be required to ensure precise carriage tracking alignment All guide rails shall have a convex top surface to provide friction-free self-centering alignment with the carriage guide wheels All carriage guide wheels shall have a concave load surface which aligns with the guide rail to provide precise carriage tracking.

Roller guide and dual flange wheel methods of guidance which have play between the guide points and the rail sides shall be unacceptable.

DIRECT DRIVE

Shaft shall be a minimum of ¾ inch diameter solid steel Drive shaft shall be a non-load bearing member of the drive mechanism for ease of movement Couplers shall be securely keyed into place to prevent looseness in the drive mechanisms Drive shaft must drive all wheels on one side of the carriage

OPERATION

Operator handles shall be provided in an ergonomic three-spoke design with rotating knobs.

All operator handles shall be provided with a minimum 1.75” diameter ergonomic push-pull knob (aisle safety lock) located at the center of the operator handleto secure adjacent carriages in place while an aisle is being occupied.
