SECTION 1: PROJECT INTRODUCTION_______________________________________________

1.1 PROJECT BACKGROUND

This project will modernize the existing elevator located that the Fort Smith National Historic Site Courthouse (Visitor Center). The elevator was originally installed in 1999 when the building underwent a completed renovation. The elevator components have reached the end of their useful life and need to be upgraded to provide safe and dependable access. The existing elevator is a hydraulic system manufactured by Schindler. It is a 3-stop hydraulic passenger lift with a basement hydraulic cylinder pit.

The elevator is located within the Park’s Visitor Center, which houses not only the displays and exhibits within the museum for the public to visit, but also the park’s administration staff, the education and interpretation staff and a bookstore. It is critical that the park modernizes the outdated elevator in order to maintain access to all floors in a manner that is consistent with the principles of universal accessibility. The Visitor center will need to remain open during the elevator modernization.

e. Provide new master door operator with the “closed loop” feature, capable of opening doors at not less than 1 ½ fps and accomplishing reversal in 2 ½ inch maximum of door movement on passenger elevator.

Doors shall open automatically when car arrives at floor to permit transfer of passengers; after timed interval, doors shall automatically close. Arrange operator so doors can be opened by hand from inside car in case of power failure, if cars are within leveling zone.

f. No Un-Necessary door Operation: The car door shall open only if the car is stopping for a car or hall call, answering a car or hall call at the present position or selected as a dispatch car.

3. Proximity Door Protection Device

The passenger car door will be protected with a 36 or more, light-ray device extending to a height of approximately 5’ 0” above the floor. The interruption of the light rays will cause the doors to remain open as long as the obstruction is in the path of one or more of the light rays.

4. Nudging

The doors shall remain open as long as the electronic detector senses the presence of a passenger or object in the door opening. If door closing is prevented for a field programmable time, a buzzer shall sound. When the obstruction is removed, the door shall begin to close at reduced speed. If the infra-red door protection system detects a person or object while closing on nudging, the doors shall stop and resume closing only after the obstruction has been removed.

The activation of any elevator lobby- sensing device shall cause the elevator to serve the lobby to return non-stop to the main floor. When the sensing device at the main floor elevator lobby is activated, the elevator that serves the lobby shall return non-stop to a predetermined alternate floor. Activation of a machine room Sensing Device shall cause the elevator to return to a predetermined landing.

The key operated switch at the main floor (described above), when turned to the RESET position, shall restore normal service independent of the sensing devices.

4. Special Service Signal:

When either the main floor key switch or a sensing device is activated and elevators are operating under a Special Service condition (including Inspection Service), both a visual and audible signal shall be activated in the cars, alerting the “attendant” to return non-stop to the main floor.

140P6219Q0019 Attachment 1 Page 20 of 22

5. Key Operated Switch in Cars:

A three-position (OFF, HOLD & ON) key operated switch shall be provided in the operating panel. It shall be effective only when the main floor key-operated switch (previously described) is in the ON position or when a sensing device has been activated and the car has returned to the main floor.

The key shall be removable in each position. When the switch is in the ON position, the elevator shall be placed on Emergency Service:

(1) The elevators shall be operable only from in the elevator.

(2) Elevators shall not respond to the elevator corridor (hall) calls.

(3) The opening of doors shall be by continuous pressure on the DOOR OPEN button. If that button is released prior to the doors reaching the fully open position, the doors shall automatically close. Fully open doors shall be closed by continuous pressure on the DOOR CLOSE button.

(4) When the switch is in the HOLD position, the car shall remain at the floor with doors open and with the DOOR CLOSE and CAR FLOOR pushbuttons inoperative.

4. An oil control valve with the following components built into single housing; high pressure relief valve, check valve, automatic unloading up start valve, lowering and leveling valve, and electro-magnetic controlling solenoids.

Install multiple oil hydraulic silencers (muffler device) at the power unit location.

The silencers shall contain pulsation absorbing material inserted in a blowout proof housing.

B. Pump: Positive displacement type pump specifically manufactured for oil-hydraulic elevator service. Pump shall be designed for steady discharge with minimum pulsation to give smooth and quiet operation. Output of pump shall not vary more than 10 percent between no load and full load on the elevator car.

C. Motor: Standard manufacture motor specifically designed for oil-hydraulic elevator service. Duty rating shall be selected for specified speed and load.

D. Oil Control Unit: The following components shall be built into a single housing. Welded manifolds with separate valves to accomplish each function are not acceptable. Adjustments shall be accessible and be made without removing the assembly from the oil line.

1. Relief valve shall be adjustable and be capable of bypassing the total oil flow without increasing back pressure more than 10 percent above that required to barely open the valve.

2. Up start and stop valve shall be adjustable and designed to bypass oil flow during start and stop of motor pump assembly. Valve shall close slowly, gradually diverting oil to or from the jack unit, ensuring smooth up starts and up stops.

3. Check valve shall be designed to close quietly without permitting any perceptible reverse flow.

4. Lowering valve and leveling valve shall be adjustable for down start speed, lowering speed, leveling speed and stopping speed to ensure smooth "down" starts and stops. The leveling valve shall be designed to level the car to the floor in the direction the car is traveling after slowdown is initiated.

5. Provided with constant speed regulation in both up and down direction.

Feature to compensate for load changes, oil temperature, and viscosity changes.

6. Solid State Starting: Provide an electronic starter featuring adjustable starting currents.

7. Oil Type: Provide a zinc free, inherently biodegradable lubricant formulated with premium base stocks to provide outstanding protection for demanding hydraulic systems, especially those operating in environmentally sensitive areas.

3.3 CLOSEOUT

3.3.1 Permits and Testing

1. At completion of installation and before final acceptance, Contractor shall perform all tests and inspections required for certification by the State of Arkansas and regulatory agency. Elevator Installer shall obtain and pay for all required inspections, tests, permits and fees for elevator installation.

2. The COR before final acceptance shall conduct test and inspection, to certify compliance with all requirements of this section.

3. Contractor shall obtain required permits and schedule tests with jurisdictional code authority.

4. Deliver to the COR upon completion and acceptance of elevator work.

3.3.2 Schematics and Capacities

1. Show equipment arrangement in the pit, hoistway and control room.

Provide plans, elevation, sections and details, erection anchorage and equipment location.

2. Indicate elevator system capacities, sizes, performances, safety features, finishes and other pertinent information.

3. Show floors served, travel distances, maximum loads imposed on the building structure at points of support and all similar considerations of the elevator work.
