D101001 GENERAL CONSTRUCTION ITEMS

Provide a traffic analysis.

NOTE:  Describe here the number and type of elevators required.  Hydraulic elevators are normally used for up to 4 story buildings.
Example wording:
"Provide a minimum of two hydraulic passenger elevators, located adjacent to the lobby area.  Provide one hydraulic freight elevator located in the shipping and receiving area.  Speed and rated load capacity of the elevator(s) shall be based on designer's survey of the facility user needs."

D101002 PASSENGER ELEVATORS

[Provide a minimum of [one] [two] hydraulic passenger elevator[s], located adjacent to the lobby area.  Speed and rated load capacity of the elevator(s) shall be based on designer's survey of the facility user needs.

Elevator finishes and fixtures shall be derived from manufacturer’s selections.  Coordinate finishes with the interior architectural design, and be responsive to the user’s needs and function. [Passenger elevators shall be sized to vertically transport the largest movable equipment or furniture used on the project.] [Utilize stainless steel wall panels and hard finish ceiling.] Coordinate the design of the elevator machine room with applicable codes and the elevator manufacturer’s requirements.

D101003 FREIGHT ELEVATORS

[Provide one hydraulic freight elevator located [in the shipping and receiving area]. Rated load capacity of the elevator(s) shall be based on designer's survey of the facility user needs.

The freight elevators shall provide vertical transportation for [_________]]

D101005 DUMBWAITERS

D101090 OTHER VERTICAL TRANSPORTATION EQUIPMENT

D1020 WEIGHT HANDLING EQUIPMENT

NOTE:  If cranes are required for the project, coordinate with the Structural Engineer. The Structural Engineer is responsible for the requirements for cranes.  Cranes with a capacity of 20 tons or greater must be procured through the Navy Crane Center.  Delete this part if not required.

 [The contractor shall be responsible for ensuring that the crane satisfies the testing and certification requirements detailed in Part 4 of this RFP to the satisfaction of the Navy Crane Center.  The contractor shall coordinate witness testing with the Navy Crane Center. ]

Certificates: For Load [Chain][Wire Rope] - [Submit certification of minimum wire rope breaking strength for each hoist. ][Submit factory certification of the load chain rated capacity.]

NOTE:  Edit this ESR to designate the WHE desired, i.e., a overhead electric bridge with electric hoist or a monorail with manual chain hoist.  If one type of equipment or other is desired from an operational or maintainability perspective, it needs to be stated and all reference to alternative equipment eliminated from ESR to prevent confusion.

NOTE:  Slow full-load operating speeds invariably provide improved load control and increased productivity.  The full-load speeds enclosed in brackets are recommended for most applications.  However, should other speeds be required, the following guidelines are provided:
 
Hoist:  See Tables 1 and 2 below.
 
Trolley: 50 fpm is recommended for one speed motorized trolleys.  For longer travel distances a two speed trolley with a high speed of 100 fpm is normally sufficient.  In any case, travel speed should not exceed the maximum speed that the floor walking, pendant control operator can comfortably negotiate in a work area, approximately 150 fpm.

NOTE:  The above note is strictly guidance and shall not be used for specifying requirements for hoist and trolley.
 
Survey the hoist and trolley commercial market and determine what standard hoist and trolley capacities and speeds are available that are suitable for the RFP.  RFP preparer shall ensure three commercial sources are available for the hoist/trolley capacity and speeds that are specified in the RFP.

D102001 OVERHEAD CRANES

[Provide a [__]-ton top-running [overhead] [underhung] electric traveling [bridge] crane in [    ].  The clear hook height shall not be less than [    ] m ([   ] ft.) above the finished floor.]

[Electrification – Runway track beam electrification for crane shall be of the [flat festooned type] [enclosed safety bar type] with four [continuous] copper conductors.]

D102002 MONORAILS

[Provide a monorail with a [manual] [air motor powered] [electric powered] hoist with a [1/4 ton] [1/2 ton] [1 ton] [1-1/2 ton] [2 ton] [3 ton] [4 ton] [5 ton] [6 ton] capacity located in the [_______].]  The clear hook height shall not be less than [    ] ft. ([   ] m.) above the finished floor.]

[Hoist and Trolley - Provide [electric] [air-powered] [manual] hoist and trolley.]  The hoist shall [have two operating speeds and shall] be capable of hoisting and lowering the rated load at a [high] speed of [20 feet per minute (fpm)] [_____].  [The trolley shall [have two operating speeds and shall] be capable of moving the rated load at a [high] speed of [50] [100] [_____] fpm.]  Actual speed(s) shall be within plus or minus 15 percent of those specified.

[Hoist and trolley motors shall be [single] [two] speed AC squirrel cage induction type.]

[Provide trolley with an electro-mechanical brake. Provide trolley brake with a minimum torque rating of [100] [50] percent of the drive motor rated torque.]

[Controls -- Provide [single] [two] speed magnetic control for the hoist and trolley.  [Provide reduced voltage starting, acceleration and deceleration for the trolley drive.]

[Manual hoist shall have a minimum rated capacity of [_____] tons.  The monorail system shall have a minimum rated capacity of [_____] tons.]

NOTE:  Do not specify a longer lift range than required, as this will increase the building height and hoist cost.  The average lift for manual hoist is 8 feet.  However, longer lifts are commercially available at additional cost per foot. Chain containers should be provided for lifts over 10 feet.
Survey the hoist and trolley commercial market and determine what standard hoist lift range available can be used for the project.  RFP preparer shall ensure three commercial sources are available for the hoist/trolley lift range that is the basis for the RFP.

Hook Operating Lift Range - [The hoist lift shall be at its highest point a minimum of [_____] feet above the finished floor and at its lowest point a minimum of [_____] feet below the finished floor.]
